Answer:

  60 ft

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

Fill in the given information and solve for h.

  8400 ft² = (1/2)(280 ft)h

  h = 8400 ft²/(140 ft) = 60 ft

The altitude of the trapezoid is 60 feet.

Mind my hand writing but I’m not sure what sign to put the “-“ or the “+” ?
Ierofanga [76]

hello!

so the answer that you put there is actually wrong and i'll tell you why and how to do it

so since you are adding the two:

-8x + 9x = x (so you got this part right)

-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)

so the final answer is x - 8

i hope this helped and have a nice day!

Amanda purchased a 30 year $10,000 bond at par value with a 4% coupon. What is the total value of the coupons
klasskru [66]

Amanda purchased a 30 year $10,000 bond at par value with a 4% coupon.

We find the coupon amount each year

Coupon amount = actual amount of bond * 4%

= 10,000 * 0.04 = 400

Coupon amount for every year = 400

Total value of coupons for 30 years = 400 * 30 = 12000

$12,000 is the total value of the coupons
