Theo borrows $8,000 for college expenses. He will pay a total of $10,280 after 6 years. What percent of interest did Theo pay?

goldenfox [79]

9514 1404 393

Answer:

4.75%

Step-by-step explanation:

When simple interest is charged, the payback amount is ...

A = P(1 +rt) . . . . for annual rate r and a term of t years

Using the given values, we can solve for r.

10280 = 8000(1 +6r)

1.285 = 1 +6r . . . . . . . . divide by 8000

0.285 = 6r . . . . . . . . . . subtract 1

0.285/6 = r = 0.0475 = 4.75% . . . . . . divide by 6; express as %

Theo paid interest at the rate of 4.75%.

Ivenika [448]

570/x = 60/100. 60% of the total amount of jigsaw puzzles is 570, we could use that information to form the equation above, where x is the total amount of pieces. The total amount of jigsaw puzzles is 950.

Bill works for a large food service company. In one hour he can make 19 sandwiches or he can make 40 salads. Bill works 7 hours

wolverine [178]

Answer:

$x=216 salads$

Step-by-step explanation:

One Hour:

Salad=40

Sandwich=19

Total work time $T=7$

Generally

Time to make 30 sandwiches is

$T_s=\frac{30}{19}$

$T-s=1.6hours$

Therefore

Bill has 7-1.6 hours to make salads and can make x about of salads in

$x=(7-1.6)*40$

$x=5.4*40$

$x=216 salads$

Examine the following table, which defines the relationship y= f(x). Then, answer the question.

erastova [34]

The slope of the function is most positive either side of x=0 and x=2π.

On the interval [0, π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2})}{(\frac{\pi}{4})} = \dfrac{2\sqrt{2}}{\pi}$

On the interval [7π/4, 9π/4], the average slope is $\dfrac{(\frac{\sqrt{2}}{2}-\frac{-\sqrt{2}}{2})}{(\frac{9\pi}{4}-\frac{7\pi}{4})}=\dfrac{2\sqrt{2}}{\pi}$

The average rate of change is highest on the intervals [0, π/4] and [7π/4, 9π/4].
