Answer:

V=180

Step-by-step explanation:

volume of the triangle =b×h

B means that the base of the prism.

to find the base use heron's formula.

and multiple with hight.

s=A+B+C/2

s=5+12+13/2=15

A=root over 15 (15-5)(15-12)(15-13) = 30

V=b×h

V=30×6

V=180

⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2

A street sign is 104 inches tall. How tall is it in feet and inches.
ikadub [295]

Answer:

8 ft 8 in

Step-by-step explanation:

104/12 = 8.666...

This shows that there are 8 total feet because there are 12 inches in a foot

Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.

Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

Ms. Lane borrowed $1,000 from her bank for one year at an interest rate of 10 percent. During that year, the price level went up
Lunna [17]

Answer:

Consider the complete question is,

'Ms. Lane borrowed $1,000 from her bank for one year at an interest rate of 10 percent. During that year, the price level went up by 15 percent. Which of the following statements is correct?

a. Ms. Lane will repay the bank fewer dollars than she initially borrowed.

b. Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.

c. Ms. Lane's repayment will give the bank greater purchasing power than it originally loaned her.

d. Ms. Lane's repayment will give the bank the same purchasing power that it originally loaned her.'  

Solution :

We have,

The borrowed amount, P = $ 1,000,

Interest rate, r = 10% = 0.1,

Time, t = 1 year,

Thus, the returned amount,

A=P(1+r)^t=1000(1+0.1)^1=1000(1.1) = \$ 1100

∵ A > P

⇒ Ms. Lane will repay the bank greater dollars than she initially borrowed.

Now,  the price level went up by 15 percent,

∵ 1000 + 15% of 1000 = 1000 + 150 = 1500

And, 1500 > 1100

⇒ Ms. Lane's repayment will give the bank less purchasing power than it originally loaned her.
