X = 10.72 (not sure if its completely right)

25^2 - 16^2 = 369
sqrt369 = 19.21
22^2 - 19.21^2 = 114.98
sqrt114.98 = 10.72

The Garzas plan to invest $2,000 for 5 years. What annual simple interest rate must the investment earn in order for the Garzas

insens350 [35]

Answer:

r=20%

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=5\ years\\ P=\$2,000\\ A=\$4,000\\r=?$

substitute in the formula above

$4,000=2,000(1+5r)$

solve for r

$2=(1+5r)$

$5r=2-1\\5r=1\\r=\frac{1}{5}=0.20=20\%$

Find the value of 7 + 32 (-5 + 1) ÷ 2.<br> A. 25<br> B. 32<br> C. -11

kobusy [5.1K]

Answer:

as written, -57
as perhaps intended, C. -11

Step-by-step explanation:

The expression shown evaluates as ...

7 + 32(-5 +1)/2 = 7 +32(-4)/2 = 7 -128/2 = 7 -64 = -57

_____

If we assume your "32" is supposed to be 3², or 3^2, then the expression evaluates differently:

7 +3²(-5 +1)/2 = 7 + 9(-4)/2 = 7 -36/2 = 7 -18 = -11 . . . . matches choice C

_____

When in doubt, you can have the Google calculator evaluate your expression. However, you do have to write it properly and with all the required parentheses.
