Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:

Dam A

f(t) = 5t – 7t – 1

Dam B

g(t) = 3t 2 + 4t + 9

Which function represents the difference in the amounts of water released, h(t) = f(t) – g(t)?

h(t) = 3t 2 – 5t + 11t + 10
h(t) = 2t 2 – 11t – 10
h(t) = 5t – 3t 2 – 3t + 8
h(t) = 5t – 3t 2 – 11t – 10

Children get a 15% discount on tickets to an amusement park. Jun had a coupon for 5% off any two tickets. He used the coupon for himself and his 4-year-old son, Jack. If regular admission for a ticket was $60, what did Jun pay for the two tickets?

Answers

The amount that Jun paid for the two tickets given the discount rate and the coupon rates is $105.45.

How much was paid for the two tickets?

Discounts and coupons reduce the price of an item.

Cost of the child's ticket after the discount = (100 - 15%) x 60 = $51

Cost of both tickets after the coupon = (100 - 5) x (51 + 60) = $105.45

Answer:

Step-by-step explanation:

Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .

3/1 1/2 (3 divided by one and one-half)

to get: 2

Then multiply it by the scale factor of 4

2*4= 8

But remeber, this is only ONE side of the garden, so multiply this by 4

8*4=32  

Next we want to see the number of links it takes to build the garden

Since one link measures 2 2/3 feet you have to divide

32/ 2 2/3 (32 divided by two and two-thirds)

to get an answer of : 12 links

Answers

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

Match each number with its opposite

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.

Answers

Answer: 5508$

Step-by-step explanation:

So to find interest your formula is this:

Int=interest rate (percent)*principal

So your problem would be: int=.02*1800

This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.
