a man earns $140 in a 5 day week. what is his pay in 3 days?

Answer:

A conditional statement is something like:

If (a condition is true) Then (something is also true.).

What this says is that ALWAYS that the condition is met, then "something" is also true.

For example:

If A > 3, then A > 2.

This is always true, because if A is larger than 3, then A is always also larger than 2.

Now, if we find a single counter-example, then the "always" is false.

This would mean that the condition is not enough, as we found a case that meets the condition, but the second part of the conditional statement is not true.

For example, if i told you that:

If a number is greater than 234, then the number is also greater than 235.

Now, there are a lot of numbers that are larger than 234 and also are larger than 235.

But here we have a counter-example.

235 is larger than 234, so the initial condition is true, but 235 is not larger than 235.

Then we find a number that makes the statement:

"If a number is greater than 234, then the number is also greater than 235."

false.

Step-by-step explanation:

The question lacks options. Find the complete question in the comment section.

Given triangle ABC, we will use the SOH, CAH, TOA trig identity to get the correct ratio.

Given the hypotenuse BC = 18 and one of the other two sides AC = 9, we can get the third side AB using Pythagoras theorem.

BC² = AC²+AB²

18² = 9²+AB²

2² = 1²+AB²

AB² = 4-1

AB² = 3.

AB = √3

Making <ABC as reference angle, AC will be opposite and AB will be the adjacent.

Sin<ABC = opp/hyp = AC/BC

Sin<ABC = 1/2

Cos<ABC = adj/hyp = AB/BC

Cos<ABC = √3/2

Tan<ABC = opp/adj = AC/AB

Tan<ABC = 1/√3

Making <BCA as reference angle, AB will be opposite and AC will be the adjacent.

Sin<BCA = opp/hyp = AB/BC

Sin<BCA = √3/2

Cos<BCA = adj/hyp = AC/BC

Cos<BCA = 1/2

Tan<BCA = opp/adj = AC/AB

Tan<BCA = √3

Frim the above calculation, the correct options are sin<ABC = 1/2, Sin<BCA = √3/2 and Tan<BCA = √3

Answer:

The indoor pool has a higher temperature and also has the greatest absolute value.

Step-by-step explanation:

The indoor pool has a higher temperature becasue 24 is greater than 23.  It also has a bigger absolute value because the absolute value how much a number is from 0.

So the absolute value of 24 is 24.

The absolute value of 23 is 23.

24 is greater so the indoor pool also has a bigger absolute value.

Answer:

See below

Step-by-step explanation:

So we have the following six values:

[tex]77.65488139\\\sqrt{0.156}\\368. 5468432...\\253,897,615.\bar3\\14.19274128...\\\\\sqrt{\frac{4}{9} }[/tex]

And we want to determine which are irrational.

Recall what irrational numbers, are they are numbers that do not repeat nor terminate. In other words, they never end, and their digits never repeat.

So, let's go through each one.

77.65488139 is rational. Yes, it has a lot of decimal places but notice there are no ellipses after it. Thus, it terminates and is rational.

√(0.156) is about (use a calculator) 0.39496835... It is not repeating nor does it end. Thus, √(0.156) is irrational.

368.5468432... has the ellipses. Thus, it doesn't repeat and doesn't terminate. It's irrational.

253,897,615.3 has a bar over the 3 at the end. This means that this repeats. Therefore, while it doesn't terminate, it is rational.

14.19274128... has an ellipses. It doesn't repeat nor terminate. It's irrational.

Lastly, the square root can be simplified to 2/3. This is approximately .6666... While this doesn't terminate, it repeats, so it's rational.

Answer:

A. The first choice.

Step-by-step explanation:

Look at function 1.

Month 1 -----> $50

Month 2  ----> $40

The difference between month 2 and moin th 1 is 1 month.

The difference between $40 and $50 is -$10. In other words, in function 1, the amount, y, went down $10 in a month. The rate of change of function 1 is -$10/month.

Function 2

y = -9x + 60

The rate of change is the slope. The slope of function 2 is -9. In function 2, the amount of money changes -$9/per month.

Answer: A. The first choice.

Step-by-step explanation:

Total coins in the jar = 50. Number of coins with a value less than $0.05 = 20 (the pennies). ... Probability of picking a penny = 20/50 = 40%. ... 'Odds' = 3 to 2 against it.

Answer:

660 exchanges

Step-by-step explanation:

Number of relatives = 12

Number of years = 5

Since each relative gives gift to one another each year:

Then each relative hands out 11 gifts (person giving out the gift will not be counted) to the others, and others also do the same.

Therefore, yearly exchange :

(Number of relatives * number of gifts given out per person)

(12 × 11) = 132

Number of exchanges after 5 years :

(Number of yearly exchanges × number of years)

(132 × 5) = 660

Answer:

the slope of W is less than the slope of Z

Step-by-step explanation:

Function Z

find slope take two points (0,15.8)  (1,15.76)

m=y2-y1/x2-x1

m=(15.76-15.8)/1-0

m=-0.04

the equation for function z : y=-0.04x+15.8

slope of W=-0.0625 which is less than -0.04

y intercept pf W=30, is greater than the y intercept of Z=15.8

Answer: The first statement is true.

Step-by-step explanation: The slope of function Z is -0.04 or - 1/25 The slope of function W is -0.0625 or -1/16.

Tricky! The absolute values of W are larger, but that makes the slope more negative.

Answer:

Percentage error is 0.0024 %

Step-by-step explanation:

Initial average distance between Earth and moon = 384467 km  

Distance measure by the scientist = 384476 km

Total variation in the distance calculation = 384476 – 384467 = 9 km.

Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.

Percentage error = ( 9 /  384467 ) × 100 = 0.0024 %

Answer:

The number of pennies owned is 7 pennies

Step-by-step explanation:

The given parameters are;

The number of pennies left over when we break the pennies into groups of 2s = 1 penny

The number of pennies left over when we break the pennies into groups of 3s = 1 penny

Let the number of pennies owned = c

What we are given are as follows;

2 × a = c - 1

3 × b = c - 1

2 × a = 3 × b

a/b = 3/2

Therefore, if we multiply 2 by 3, and 3 by 2 we get 6

2 × 3 = 6, similarly 3 × 2 = 6

If we put 6 = c - 1, we get;

c = 6 + 1 = 7

c = 7

The number of pennies owned = 7 pennies.

Answer:

20°

Step-by-step explanation:

The sum of angles in a ∆ = 180°

Therefore, [tex] (17x - 1) + (3x - 4) + 25 = 180 [/tex]

Use this expression to find the value of x, then find the measure of angle A.

[tex] 17x - 1 + 3x - 4 + 25 = 180 [/tex]

[tex] 17x + 3x - 1 - 4 + 25 = 180 [/tex]

[tex] 20x + 20 = 180 [/tex]

Subtract 20 from both sides

[tex] 20x + 20 - 20 = 180 - 20 [/tex]

[tex] 20x = 160 [/tex]

Divide both sides by 20

[tex] \frac{20x} = \frac{160}{20} [/tex]

[tex] x = 8 [/tex]

Find measure of angle A.

Angle A is given as [tex] 3x - 4 [/tex]

Plug in the value of x and solve

[tex] A = 3(8) - 4 = 24 - 4 = 20 [/tex]

Answer: Hi!

To find the mean of a data set, you have to add the numbers in the set and then divide the sum by the number of values that are in the set.

Answer:

Option (F)

Step-by-step explanation:

Cosec of an angle is the ratio of Hypotenuse and Opposite side.

From the figure attached,

ΔABC is a right triangle.

m∠A + m∠B + m∠C = 180°

m∠A + 90 + x = 180

m∠A = 180° - (90 + x)°

        = (90 - x)°

Now csc (90 - x)° = [tex]\frac{\text{Hypotenuse}}{\text{Opposite side}}[/tex]

                            = [tex]\frac{\text{AC}}{\text{BC}}[/tex]

                            = [tex]\frac{5}{3}[/tex]

                            = 1.67

Therefore, Option (F) will be the answer.

Answer:

rational. I can't read the answer choices well.

The correct statement is: "It's rational because 6.24 repeated can be expressed as a fraction." Option A is true.

Here, we have,

To determine if 6.24 repeated is rational or irrational, we need to evaluate the options provided:

A) It's rational because 6.24 repeated = 68∕33.

To evaluate this option, we can convert 6.24 repeated into a fraction form.

Let x = 6.24 repeated.

We can multiply x by 100 to eliminate the repeating decimal:

100x = 624.24 repeated

Subtracting the original equation (x = 6.24 repeated) from the new equation (100x = 624.24 repeated), we can eliminate the repeating decimal:

100x - x = 624.24 repeated - 6.24 repeated

99x = 618

Simplifying:

x = 618/99

Now, let's check if 618/99 equals 6.24 repeated by calculating its decimal value.

Using a calculator, we find that 618/99 is approximately 6.242424..., which matches the repeating pattern.

Therefore, option A is true.

B) It's irrational because 6.24 repeated = 66∕25.

To evaluate this option, we can calculate the decimal value of 66/25 using a calculator. It turns out that 66/25 is approximately 2.64, which is not equal to 6.24 repeated. Therefore, option B is false.

C) It's rational because 6.24 repeated = 66∕25.

To evaluate this option, we can calculate the decimal value of 66/25 using a calculator. It turns out that 66/25 is approximately 2.64, which is not equal to 6.24 repeated. Therefore, option C is false.

D) It's irrational because 6.24 repeated = 68∕33.

To evaluate this option, we can convert 6.24 repeated into a fraction form. As we determined earlier, 6.24 repeated is rational. Therefore, option D is false.

The correct statement is: "It's rational because 6.24 repeated can be expressed as a fraction." Option A is true.

Answer:

Square= 12 units

Triangle long sides= 19 units

Triamgle short side= 10 units

Step-by-step explanation:

It is a square, so all sides are the same.  That means 3x+3 equals 4x.  What number can be subsituted into x to equal 4?  If x is 3, then 3x+3 would be 3(3)+3.  It equals 12.  4 times 3 is also 12.  It works!  That also means the square's side is 12 units.

Square= 12 units

So, x=3

The triangle's longer sides are 7x-2.  Subsitute x in, which is 3, and you get 7(3)-2.  It equals 19.  The two longer sides of the triangle are the same length, so both are 19 units.

Triangle long sides= 19 units

The triangles shorter side is 2x+4.  Subsitute 3 in for x and you get 2(3)+4.  It equals 10, so the shorter side is 10 units.

Triangle short side= 10 units

Answer:

Square: 12 unites

triangle shorter side: 10 units

triangle longer sides: 19 units, 19 units

Step-by-step explanation:

Hello!

First, we make the equations to find the perimeters of each shape by adding all the sides

Square: 4x + 4x + (3x+ 3) + (3x + 3)

Triangle: (7x - 2) + (7x - 2) + (2x + 4)

Since the perimeters are equal we can show that

4x + 4x + (3x+ 3) + (3x + 3) = (7x - 2) + (7x - 2) + (2x + 4)

Now we can solve for x.

Combine like terms

14x + 6 = 16x

Subtract 14x from both sides

6 = 2x

Divide both sides by 2

3 = x

Now we know what x is we can put that into the sides of the shapes

Square

4(x)

Put in x

4(3) = 12

The Square is 12 units

Triangle Short Side

2x + 4

Put in x

2(3) + 4

6 + 4

10

The shorter side of the triangle is 10 units

Triangle Longer Side

7x - 2

Put in x

7(3) - 2

21 - 2

19

The longer sides are 19 units

Answer:

The cost of producing the article is -3500 (Negative cost)

Step-by-step explanation:

The given parameters are

The ratio of the profit to material cost to production labor = 5:7:13

The amount of the material cost = 840 + Labor cost

Let the total cost = X

Therefore, we have;

The fraction of the total cost that is material cost = 7/(5 + 7 + 13) = 7/25

Therefore, the material cost = 7/25 × X

The fraction of the total cost that is labor cost = 13/(5 + 7 + 13) = 13/25

Therefore, the labor cost = 13/25 × X

However, the amount of the material cost = 840 + Labor cost, which gives;

7/25 × X = 13/25 × X + 840

7/25 × X - 13/25 × X = 840

-6/25 × X= 840

X = 840/(-6/25) = 840×(-25/6) = -3500

The cost of producing the article = -3500.

Answer:

A. 264

Step-by-step explanation:

When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs. Therefore,

60° = 1/2[(18x - 6)° - (5x +17)°]

60° * 2 = (18x - 6 - 5x - 17)°

120° = (13x - 23)°

120 = 13x - 23

120 + 23 = 13x

143 = 13x

143/13 = x

11 = x

x = 11

(18x - 6)° = (18*11-6)°= (198 - 6)° = 192°

(5x +17)° = (5*11 +17)° =(55+17)° = 72°

m (arc KNL) = (18x - 6)° + (5x +17)° = 192° + 72°

Slope of the line is = [tex] \frac{5}{2} [/tex]

y-intercept = 5

Step-by-step explanation:

Slope (m) is can be calculated using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use the coordinates of any two points located on the line. Let's use, (14, 40) and (10, 30).

Let,

[tex] (14, 40) = (x_1, y_1) [/tex]

[tex] (10, 30) = (x_2, y_2) [/tex]

Plug the above values into the formula to find the slope (m).

[tex] m = \frac{30 - 40}{10 - 14} [/tex]

[tex] m = \frac{-10}{-4} = \frac{5}{2} [/tex]

Slope of the line is = [tex] \frac{5}{2} [/tex]

Find y-intercept using y = mx + b

Where m = slope, and b = y-intercept

Use (10, 30) as (x, y).

30 = 5/2*10 + b

30 = 25 + b

30 - 25 = b

5 = b
