Answer:

14.765 units

Step-by-step explanation:

distance formula

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(4 + 3)² + (8 + 5)²]

d = √(7²) + (13²)

d = √(49 + 169)

d = √218

d = 14.765

Answer:

1.625

Step-by-step explanation:

So you have to convert the 5/8ths into something that can go into 10.

So 100/8 is equivalent to 12.5. But you'll have to make that into decimal form, so move that 2 places to the right, to get 0.125. 0.125 times 5 is 0.625. And 1 is just 1 as a whole number. 1 plus 0.625 is 1.625.

The decimal form of the given number [tex]1\frac{5}{8}[/tex] is 1.625

In Algebra, decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point.

Given is a fractional number  [tex]1\frac{5}{8}[/tex], we need to find the decimal form of it,

Converting  [tex]1\frac{5}{8}[/tex] into fraction,

[tex]1\frac{5}{8}[/tex] = 13/8

When we divide 13 by 8, we will get 1.625

Hence, the decimal form of the [tex]1\frac{5}{8}[/tex] is 1.625

Answer:

99.4%

Step-by-step explanation: 2500 - 15 = 2485

2485/2500 = 0.994 x 100 = 99.4%

Answer:

99.4%

Step-by-step explanation:

Total number of people tested = 2500

People who had allergic reaction = 15

People who didn't have allergic reaction = 2500 - 15 = 2485

Percentage = Part of a whole / The whole

=> 2485 / 2500

=> 497 / 500

=> .994

To convert a decimal into percent:

=> We need to make the decimal point move 2 times to the right

=> .994

=> 99.4%

So, 99.4% of the people who were tested, didn't have an allergic reaction.

Answer: 42 gallons

Step-by-step explanation:

given data:

average gas mileage/day = 29miles/gallon

distance travelled each day by James = 87miles

How much gas does he use in 14days drive.

solution:

james drives 87miles daily, so in 14 days he would have travelled

= 87miles * 14

= 1218miles travelled.

gas used in 14days

1218miles distance traveled in 14 days

29miles/gallon

= 1218miles / 29miles

= 42gallons of gas have been used by janew to fuel his truck in 14days.

Answer:

6837 cm is less than 68 hm

Step-by-step explanation:

1 hectometres  = 100 meters

1 centimetres = 0.01 meters

Therefore;

6837 centimetres = 6837 × 0.01 meters = 68.37 meter

6837 centimetres = 68.37 meter

Also, we have;

68 hectometres  = 68 × 100 meters = 6800 meters

68 hectometres  = 6800 meters

Therefore,

6837 centimetres = 68.37 meter < 68 hectometres  = 6800 meters

6837 centimetres < 68 hectometres  

6837 cm < 68 hm

6837 cm is less than 68 hm.

Answer:

-2x +18 or 18 - 2x

Step-by-step explanation:

You have 3x and you have -5x so take 5 away from 3 to get -2x

Then you have +8 and +10 so add them together and you get an answer of 18

Put the two answers from the equation together and you have got 18-2x

Hope this helps :)

Start by changing the problem to 3x + 8 + -5x + 10.

Combine like terms → your numbers and your "x" terms.

So 3x + -5x is -2x and 8 + 10 is 18.

So the answer is -2x + 18.

The definition of a function is that every output (x) has only one input (y).

Here -3 gives two different outputs which contradicts the definition of a function.

Answer:

dy/dx = -b/a cot α

Step-by-step explanation:

x² / a² + y² / b² = 1

Take derivative with respect to x.

2x / a² + 2y / b² dy/dx = 0

2y / b² dy/dx = -2x / a²

dy/dx = -b²x / (a²y)

Substitute:

dy/dx = -b²a cos α / (a²b sin α)

dy/dx = -b cos α / (a sin α)

dy/dx = -b/a cot α

Answer:

13.26

Step-by-step explanation:

The computation of the height should be computed by using the Pythagoras theorem

As we know that

Hypothenuse^2 = base^2 + height^2

where,

Hypothenuse is 15 foot

And, the foot of the ladder i.e base is 7

So now placing these values

The height is

15^2 = 7^2 + height^2

225= 49 + height^2

After solving this, the height is 13.26

Answer:

AB = 10.6 cm

Step-by-step explanation:

In triangle FGH, FG = 12.3 cm, GH = 10.6 cm, m angle G=80 degrees, and m angle H=55 degrees. If triangle ABC GHF, which statement is true?

A. AB = 12.3 cm

B. AB = 10.6 cm

C. M angle C=55 degrees

D. M angle C=80 degrees

Answer:

If triangle ABC ≅ GHF, This means triangle ABC is congruent to triangle GHF.

Two triangles are congruent if the three sides and three angle of one triangle is equal to the three sides and three angle of the other triangle.

Hence the corresponding sides and angles of triangle FGH is equal to the corresponding side and angle of triangle ABC.

AB = GH

AB = 10.6 cm

m∠F + m∠G + m∠H = 180° (sum of angles in a triangle)

m∠F + 80 + 55 = 180

m∠F + 135 = 180

m∠F = 180 - 135 = 45

m∠F = 45°

m∠F = m∠C

m∠C = 45°

Answer:

[tex]\Huge \boxed{a_4=2}[/tex]

Step-by-step explanation:

The third term in an arithmetic sequence is 7.

The common difference is -5.

The common difference of an arithmetic sequence is found by subtracting a term in the sequence with the previous term.

[tex]d=a_4-a_3[/tex]

Solving for the fourth term.

[tex]a_4 = a_3 + d[/tex]

Plugging in the values and evaluating.

[tex]a_4=7+-5[/tex]

The value of the fourth term is 2.

Answer:

x = 15

Step-by-step explanation:

Angle Formed by Two Secants = 1/2(DIFFERENCE of Intercepted Arcs)

2x +15 = 1/2 (10x+20 - 80)

Multiply by 2

4x+30 = (10x+20 - 80)

Combine like terms

4x+30 = 10x-60

Subtract 4x from each side

30 = 6x-60

Add 60 to each side

90 =6x

Divide by 6

a) all integers are not rational numbers because 2/10 is a rational number but not an integer.

c) all whole numbers are not natural numbers because 0 is not a natural number.

d) all irrational numbers are not real numbers because root2 is not a real number.

b) it is true.

Statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

As we know,

The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.

It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.

A rational number is a sort of real number that has the form p/q and does not equal zero.

Thus, statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

Answer:

Option (B)

Step-by-step explanation:

If we graph the points given in the table, a straight line is obtained which shows that the table given represents a linear function.

Let the two points on the graph are (4, 31) and (8, 37)

Slope of the line passing through these points,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{37-31}{8-4}[/tex]

   = 1.5

Equation of the line passing through a point (4, 31) and slope = 1.5 will be,

y - y' = m(x - x')

y - 31 = 1.5(x - 4)

y = 1.5x - 6 + 31

y = 1.5x + 25

Therefore, Option (B) will be the answer.

Answer: p = 1/6.

Step-by-step explanation:

First, we have two fair dice, so we have two events.

The number of outcomes for each dice is 6, then the total number of outcomes for the two dice is equal to the product of the number of outcomes in each event.

C = 6*6 = 36.

Now, the combinations that have a sum larger than 10 are:

4 and 6.

6 and 4

5 and 5

5 and 6

6 and 5

6 and 6.

So we have 6 outcomes where the sum of both numbers is larger than 10.

Now, the probability will be equal to the quotient between the number of outcomes where the sum is larger or equal than 10, and the total number of outcomes:

P = 6/36 = 1/6.

[tex]\huge\boxed{3x-3}[/tex]

Step-by-step explanation:

[tex]3(x-1)=\\\\\text{Distribute: }\left \{ {{3*x=3x} \atop {3*-1=-3}} \right.\\\\3(x-1)=\boxed{3x-3}[/tex]

The distributive property is a very important property used in algebra.

It states that when we have the statement a(b + c), we can "distribute" the

a by multiplying a times both terms that are inside the parenthses.

So that would give us a(b) + b(c) or ab + bc.

The same process is done here.

Distribute the 3 through both terms to get 3(x) - 3(1) or 3x - 3.
