Answer:

6 different sized paving stones,$16

Complete question:

What if the 360 cubic-inch paving stones are 4 inches thick and any whole number length and width are possible? How many different paving stones could be made? Suppose that the cost of having stone is $2.50, plus $0.15 for every 4 cubic inches of concrete how much would each paving stone cost?

Step-by-step explanation:

V= B x h

B= V / h=> 360 / 4  

B= 90 sq inch

Considering the factors of 90: 1,2,3,5,6,9,10,15,18,30,45,90

Now, make table with base height and volume for each pair of factors. (see figure in the attachment)

We'll have 6 different sized paving stones.

As each stone has a vol of 360 inches³. Diving by 4 in order to find how many 4 inch³ per stone

Concrete=$0.15 x (360/4) => $0.15 x 90

Concrete= $13.5

The cost of the stone plus the concrete will be:

cost= $2.50 + concrete

cost= $2.50 + $13.5

cost=$16

4*10^6 is how many times as large as 1*10^4?
maxonik [38]
So you want to know how many times  4*10^6 fits inside 1*10^4, if so, here's the answer:

First we see that 4*10^6 is equal to <span>4,000,000, and</span> 1*10^4 is equal to 10,000.

Then we divide \frac{4,000,000}{10,000}, and we get 400, so.

The answer is 400.

Hope this helped! c:

Find the value of x, which makes the area of this triangle equal 72.
Ghella [55]
Area of a triangle=1/2(base x height)
Area=72, Base=8, Height=2x-3
Plug it in.
72=1/2(8 x (2x-3))
72=1/2(16x-24)
72=8x-12
84=8x
x=10.5

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi
PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

10^2+b^2=26^2

Solve the exponents

100+b^2=676

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

100-100+b^2=676-100

b^2=576

Take the square root of both sides

\sqrt{b^2}=\sqrt{576}

b=24

So, the other leg is 24 mm
