for every 5 coins carmen gets, she gives 2 to her brother frank. if carmen has 9 coins, how many does frank have? Explain.

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.

9:16

Step-by-step explanation:

If there are 9 dogs and 7 cats and you need to know the total number of cats and dogs add the numbers together (16) and put the number of dogs in front of it (9). So the answer is 9:16

Answer:

9:16

Step-by-step explanation:

because he ratio of cats to dogs is 9:7, so that means the 9 is how many dogs their are, 9 + 7= 16, making 9:16 (i'm wrong i'm positive i might be right)

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:

930 mph

Step-by-step explanation:

Answer:

930 miles

Step-by-step explanation:

first divide 558 by 3 to find how many miles a train travels in 1 hour. 558/3 = 186. Then multiply 186 by 5 and get 930 miles

To solve the problem we will firstly rearrange the given expressions to get like terms together.

like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

If we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

Given to us

we know to subtract an expression from another we need to find the like terms of both expressions to carry out the mathematical operation.

therefore,

[tex](8x-10) - (9x^2+7x-2)\\\\=8x-10 - 9x^2-7x+2\\\\= -9x^2 +8x-7x-10+2\\\\= -9x^2 +x -8[/tex]

Hence, if we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

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

Step-by-step explanation:

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.

Step-by-step explanation:

The correct answer is adding by 4

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.
