Step-by-step explanation:

Answer:

a) 2/7 cup

b) k = 2/7

Step-by-step explanation:

2 cups of red paint (R) require 7 cups of white paint(W)

We can write this as a proportion equation:
R = k.W

where k is the constant of proportionality

Given R =2 when W = 7 we get

2 = k . 7

k = 2/7

Constant of proportionality = 2/7

So for 1 cup of White paint we will need
R = 2/7 x 1 = 2/7 cup

Answer:

27 found this answer in ohio

Step-by-step explanation:

We want to multiply the following 2 fractions:

3

4

x

36

1

Multiplying 2 fractions involves multiplying both numerators divided by both denominators.

Numerator 1 x Numerator 2

Denominator 1 x Denominator 2

In this case, Numerator 1 = 3, Denominator 1 = 4, Numerator 2 = 36, Denominator 2 = 1, so we have:

3 x 36

4 x 1

108

4

Now that we have our preliminary answer, we need to reduce it down as much as possible.

From our GCF Calculator, we see that the highest number that reduces 108 and 4 down to an integer is 4.

This number, 4, is called our Greatest Common Factor (GCF), and will be used to reduce both numerator and denominator as seen below.

Reducing the numerator gives us: (1/4) x 108 = 27

Reducing the denominator gives us: (1/4) x 4 = 1

Our answer is just the reduced numerator divided by the reduced denominator.

Since our reduced answer is a whole number, we remove the one from the denominator and write it as:

Answer = 27

Answer:

As a mixed number it would be 1 3/7

2 different fractions could be 20/14 and 40/28

10/7 x 2 = 20/14

10/7 x 4 = 40/28

Answer:

54 mph

Step-by-step explanation:

Since Car B travels 9 more miles in 10 more minutes, you would need to multiply  10 by 6 and 9 by 6 to get 54 miles per 60 minutes or 54 mph. And this would work because Car A would travel 36 miles and Car B would travel 45 miles and 45 - 36 is 9.

The slope of a line can be found using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line.

Plugging in the given points, we get:

m = (-4 - (-7/2)) / (2 - (-3)) = 3/2 / 5 = 3/10

So, the slope of the line is 3/10, which is equal to one tenth.

Therefore, the answer is "one tenth."

Answer:

6 remainder of 5

Step-by-step explanation:

59 does not divise cleanly so you to the closest number that does and that number is 6 then you minus 59 from 54 bc 9 times 6 is 54 and 59 minus 54 is 5 so five is what remains meaning it becomes remainder 5

Answer:

b

Step-by-step explanation:

if its located after 1 it would need to be between 1 and 2 on the line so b is the only one that is there

====================================================

Explanation:

Let's label the given points A, B and C

To move from B to C, we do two things in either order:

This motion of "down 2, right 7" is copied or mirrored when we go from A to D. This is to ensure that BC is parallel to AD.

Start at point A and go down 2 units to get to (-6, -4). Then move 7 units to the right to arrive at (1, -4) which is the location of point D. You can use a tool like GeoGebra to verify the answer is correct.

Answer:

27 cm squared

Step-by-step explanation:

r = half of the diameter = 8 cm

area of circle = pi(r)^2 = 3.14 x (8 cm)^2 = 200.96 cm squared

area of rectangle = 16 cm x 8 cm = 128 cm squared

area of shaded region = area of the rectangle - (half of the area of the circle)

half of the area of the circle = 100.48 cm squared

therefore, area of shaded region = 128 cm squared - 100.48 cm squared

= 27.52 cm squared

Answer:

B) 72

Step-by-step explanation:

The value of 80-2n when n=4 can be found by substituting n=4 into the expression and simplifying. Therefore:

80-2n = 80 - 2(4) = 80 - 8 = 72

Therefore, the answer is B) 72.

Put n = 4
