what single decimal multiplier would you use to decrease by 7% followed by a 20% decrease

Answer:

G. 12 cm

Step-by-step explanation:

Length of one leg of right triangle = a = 9 cm

Length of hypotenuse = c = 15 cm

Length of the other leg = b = ?

Applying pythagorean theorem, c² = a² + b², we have:

15² = 9² + b²

15² - 9² = b²

144 = b²

b = √144

b = 12

Answer:

A

Step-by-step explanation:

The volume of a rectangular prism is:

[tex]V=\ell wh[/tex]

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

[tex]V=(2)(2)h=4h[/tex]

So, we can write:

[tex]V=4h[/tex]

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.

So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

[tex]\displaystyle V=4\Big(\frac{2}{3}\Big)t=\frac{8}{3}t[/tex]

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

[tex]\displaystyle 64 = \frac{8}{3} t[/tex]

Solve for t:

[tex]\displaystyle t=\frac{3}{8}(64)=3(8)=24\text{ minutes}[/tex]

The correct answer is A.

Answer:

The variables are A and B. A for Andy, and B for Brett. B=18, and A=26

Step-by-step explanation:

A+B=44

A=B+8

B + 8 + B = 44

2B+8=44

2B = 36

B = 18

A = 26

D.

Step-by-step explanation:

Answer:

the answer to this question is d.

Answer:

Below.

Step-by-step explanation:

In a right triangle:

sin x = opposite side / hypotenuse

cos x = adjacent side / hypotenuse

tan x = opposite side / adjacent side

In this triangle the hypotenuse = 12 and the adjacent side = h

so we use cos 47

cos 47 = h / 12

h = 12 cos 47

h = 8.2 cm.

Answer:

h = 18.88 inches

Step-by-step explanation:

Given that,

The circumference of a cylinder is 20 inches

The volume of the cylinder, V = 600 cubic inches

We need to find the height of the cylinder. We know that the volume of a cylinder is given by :

[tex]V=\pi r^2h[/tex]

r is radius

We know that,

circumference = 2πr

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{20}{2\pi}\\\\r=3.18\ \text{inches}[/tex]

So,

[tex]h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{600}{\pi\times (3.18)^2}\\\\h=18.88\ \text{inches}[/tex]

So, the height of the cylinder is 18.88 inches.

The area of the land is 1250 square meters.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length by the width.

So the formula for finding the area of the rectangle is

Area = Length * Width

In this case, the land is 25 meters wide and 50 meters long, so the area is:

Area = length × width

Area = 50 m × 25 m

Area = 1250 m²

Hence, the area of the land is 1250 square meters.

Answer:

3/8 + 1/4 is 5/8 and 1/10+4/5 is 1

Step-by-step explanation:

convert 1/4 to 2/8 and add to 3/8 to get 5/8

convert 4/5 to 9/10 and add to 1/10 equals 10/10 which is also 1

Answer:

9/10 (and 5/8 for question in title)

Step-by-step explanation:

To add fractions, you need to make a common denominator, which you can have a common denominator of 10.

To do this, multiply the numerator (4) and the denominator (5) by 2. You will get 8/10.

Now you can add them together: 8/10 + 1/10 = 9/10

I don't know if you wanted the question in the title answered too so here:

Same thing; common denominator. Use 8. Multiply 1 by 2 and 4 by 2. You get 2/8.

Add: 3/8 + 2/8 = 5/8
