Sam deposits $1,000 into an account that pays 6% simple interest annually. He plans to take the money out after 3.5 years. What
lara31 [8.8K]
Well, the formula for simple interest is 

I=prt

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.

If you substitute the numbers, you get

I=1,000(0.06)(3.5)

When you multiply them together, you get 

I=210

So, the simple interest for 3.5 years is $210.

But, in order to get the total balance, you have to add the interest and the principal together.

B=1000+210 \\ B=1210

So, the balance after 3.5 years is $1,210.

Given f(x) = -3x + 21, find x when f(x) = 6.
Ainat [17]

Answer:

x = 5

Step-by-step explanation:

Given

f(x) = - 3x + 21 and f(x) = 6, then equating gives

- 3x + 21 = 6 ( subtract 21 from both sides )

- 3x = - 15 ( divide both sides by - 3 )

x = 5

8. In the figure, ADC is a straight line.
dlinn [17]

Answer:

a). ΔABC ~ ΔBDC

b). m(BD) = 6 units

Step-by-step explanation:

If ΔABC ~ ΔBDC,

a). Ratio of the corresponding sides of both the triangles will be equal.

\frac{AB}{BD}=\frac{BC}{DC}=\frac{AC}{BC}

\frac{BC}{DC}=\frac{AC}{BC}

\frac{12}{9}=\frac{7+9}{12}

\frac{4}{3}=\frac{4}{3}

Since Ratio of the corresponding sides are same, therefore, both the triangles are similar.

b). \frac{AB}{BD}=\frac{BC}{DC}

\frac{8}{BD}=\frac{12}{9}

BD = \frac{9\times 8}{12}

BD = 6
