Answer:

The answer is B (AKA) 102

Step-by-step explanation:

180-78

one angle is 180 degrees

Answer:

102

Step-by-step explanation:

These two angles together add up to 180 degrees because they are supplementary. All you have to do to find this answer is subtract 78 from 180 to get 102.

180-72=102

Answer:

5 : 18 : 12

Step-by-step explanation:

Express the ratio B : C  in fractional form, that is

[tex]\frac{B}{C}[/tex] = [tex]\frac{6}{4}[/tex] ( cross- multiply )

6C = 4B ( divide both sides by 6 )

C = [tex]\frac{4}{6}[/tex] B = [tex]\frac{2}{3}[/tex] B , then

C = [tex]\frac{2}{3}[/tex] × 18 = 2 × 6 = 12

Hence

A : B : C = 5 : 18 : 12

Answer:

5:18:12

Step-by-step explanation:

5:18

_:6:4 --> since you multiply 6 by 3 to get 18, multiply 4 by three to get the A:B:C ratio.

Answer:

Perpendicular

Step-by-step explanation:

the lines are Perpendicular or it can also be parallel

The lines in Graph 1 is neither, graph 2 is parallel, graph 3 is parallel and graph 4 is perpendicular.

Parallel lines are those straight lines in a plane which will not intersect each other even if we extend the line to infinity.

Perpendicular lines are those lines where the two lines meet a point where the angle between the two lines is 90 degrees.

Graph 1 :

Lines are not parallel because if we extend one line it will meet the other line.

Lines are not perpendicular since the point of intersection will never make the angle between the lines as 90 degrees.

So it is neither parallel nor perpendicular.

Graph 2 :

The two lines will never intersect if we extend the line infinity.

So they are parallel.

Graph 3 :

Again the lines are parallel since they won't intersect at any point.

Graph 4 :

Since both the lines make a 90 degree angle at the point of intersection, they are perpendicular.

Hence the lines are parallel in graph 2 and 3, lines are perpendicular in graph 4 and lines are neither in graph 1.

[tex]2(n-2)<3n-6[/tex]

↝ Multiply 2 inside (n-2) as we get 2n-4

[tex]2n-4<3n-6[/tex]

↝ Inequality is almost the same as equation so you just do the same like equation.

[tex]2n-4-3n+6<0\\-n+2<0\\-n<-2[/tex]

↝ Since it's Inequality. When the variable is negative, you have to make it positive.

[tex]n<\frac{-2}{-1}\\n<2[/tex]

↝ BUT! n < 2 isn't the right answer.

↝ Because for Inequality. Taking out the negative/Move the negative variable to another side ( from -n to n and -2 to -2/-1 = 2).

↝ You have to swap the inequality symbol after taking the off the negative variable.

↝ For example, if it is -n < 2 then the answer will be n > -2

or -n < -3 then the answer will be n > 3

But if it is n>2-3 as we get n>-1, not n < -1 because the variable isn't negative at all.

Basically, we swap the inequality symbol when it's negative variable.

↝ Therefore, it's not n < 2 but it is n > 2

So the right choice is n > 2 also known as the ( D ) answer.

Answer:

each would take about 8 hours. all youd need to do is divide 100 kilo by 12 because thats how much he runs in one hour. so 100 kilometers per week would take 8.3, which is rounded to ~about~ 8

The true statement is Each treadmill session takes about 2 hours.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

He runs at a constant speed of 12 kilometers per hour for 5 days per week.

If he runs 100 kilometers per week

So, each day he runs

= 100 /5

= 20 Km

and, he runs 20 Km in

= 20 /12

= 1.666

= 2 hours approximately.

Hence, Each treadmill session takes about 2 hours.

Answer:

y = 360x+200

Step-by-step explanation:

We will use the concept of finding the equation of a line using two coordinates (x1,y1) and (x2,y2)

If after 3 months, ethan has 560 dollars in his savings, and after 6 months, he has 920 dollars, this can be represented as coordinate points (3,560) and (6,920)

The equation of a line in point slope form is expressed as;

y = mx+c

m is the slope = ∆y/∆x = 920-560/6-3

m = 360/3

m = 120

Get the intercept;

Substitute m = 120 and any of the points to get c, using the point (3,560)

x = 3, y = 560

560 = 120(3)+c

560 = 360+c

c = 560-360

c = 200

Get the required equation by substituting m and c into y = MX+c

y = 360x+200

Answer:

$34.40

Step-by-step explanation:

this equation has 3 steps

1. to find out how much the dvds cost without any discount or tax: $40

2. the price of the dvds with the 20% discount, which can be found with cross-multiplication making the price after discount $32

3. the final price of the dvds with sales tax can be found also with cross-multiplication and the final answer would be 34.4

Answer:

$34.7

Step-by-step explanation:

40 x 0.0675 to find the tax.

40 x 0.8 to find how much to pay

40 x 0.0675 = 2.7

40 x 0.8 = 32

32 + 2.7 = 34.7

Answer: See explanation

Step-by-step explanation:

a) A large pizza with one topping costs $15.50. A large pizza with 4 toppings costs $20.

A large pizza with one topping costs $15.50.

Using the formula for direct variation,

y = kx

where,

y = Cost of pizza

x = number of toppings

k = constant of proportionality

15.50 = 1k

k = 15.50

A large pizza with 4 toppings costs $20.

Using y = kx

20 = 4k

k = 20/4

k = 5

Here, the price does not vary directly with the number of toppings because the constant of proportionality is different.

b) A marathoner ran 5 miles in 40 minutes and 15 miles in 120 minutes.

Using y = kx

where,

y = 40

x = 5

y = kx

40 = 5k

k = 40/5

k = 8

Using y = kx

where,

y = 120

x = 15

y = kx

120 = 15k

k = 120/15

k = 8

The number of minutes vary directly with the number of miles. This is because the constant of proportionality is thesame in both cases.

Therefore, the second one(B) represents a direct variation and the first one (A) doesn't.

Answer:

45 feet

Step-by-step explanation:

Area of a rectangle = length × width

Area of the rectangle = 1,125 square feet

Length of the rectangle = x feet

Width of the rectangle = 25 feet.

What is the length of the parcel of land?

Area of a rectangle = length × width

1,125 = x * 25

1,125 = 25x

Divide both sides by 25

x = 1,125 / 25

= 45

x = 45 feet

The length of the parcel of land is 45 feet

Answer:

y = (1/2)x + 2

Step-by-step explanation:

Find the slope:

Take the rise over run to find this- For every unit it goes up, it goes two units across, so it will be (1/2)

Find the y-intercept:

This is the value of y where the line intersects the y-axis- (0,2), so 2

Substitute these values in for m and b:

y = mx + b

y = (1/2)x + 2

  Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.

Step-by-step explanation:

The standard form has mutually prime integer coefficients, with the leading coefficient positive. Clearing Katrarina's fraction of 2/3 can be accomplished by multiplying the equation by 3/2, as Sofiya advised.
