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: The circumference of the cylinder's base is 6 units.

Radius = 1/2(6/pi)

Volume = r2pi*h

h = (27/2) / r2pi

sin(∠BAD) = h / 6

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.

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.

[tex] \sf80 - 2n[/tex]

Put n = 4

[tex] \tt80 - 2 \times 4 \\ \tt80 - 8 \\ \boxed{ \sf\underline{ \underline{72}}}[/tex]

Step-by-step explanation:

15.4 (the original temperature) + 11.6 (the amount that the lifeguard adds) = 27, therefore the final water temperature is 27.0 degrees celsius

Answer:

The answer to your question is 27.0° C.

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:

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:

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

Volume is calculated using the formula volumes = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.

Explaining a triangle

Triangles: What are they? Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed by a point where the three are joined end to end. The triangle's three angles add up to a total of 180 degrees.

Answer: What is a triangle?

A triangle is made up of three vertices, three angles, and three sides. A triangle's internal angles add up to 180 degrees. The triangle's third side is longer than the two sides added together. where is

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

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."

Step-by-step explanation:

The inequality that shows the scores Miriam could get to pass her math class will be x ≥ 0.82y.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

To pass this year’s math class, Miriam needs to earn at least 82%.

Let 'x' be the number of marks that Miriam needs to pass and 'y' be the total marks. Then the inequality is given as,

(x / y) × 100 ≥ 82%

Simplify the inequality, then we have

(x / y) × 100 ≥ 82%

(x / y) ≥ 0.82

x ≥ 0.82y

The inequality that shows the scores Miriam could get to pass her math class will be x ≥ 0.82y.

Answer:

1 unit

Step-by-step explanation:

The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is 2/3 unit, and the width is 1/3 unit, what is the perimeter of the rectangle in units?

perimeter = 2(l + w)

perimeter = 2(2/3 + 1/3)

perimeter = 2(3/3) = 2(1)

perimeter = 1

Answer: 1 unit

Answer:1 Fraction 2 over 3 units
