Answer:

23 degrees

Step-by-step explanation:

You are given a right angle, which is 90 degrees. Part of the right angle is 67 degrees, so you do 90-67=23

Hope this helps ^^

Answer:

23 degrees

Step-by-step explanation:

This is because angle B and the angle that is 67 degrees are both apart of one right angle. We can solve this through a simple equation. 90 = x +67. Subtract 67 on both sides and you get X = 23 giving you the answer 23 degrees.

The answer is 20/26 but it could also be 10/13 when simplified

What is the solution of 7x + 14 - 3x = 30?<br> O<br> A. 4<br> o<br> B. -11

max2010maxim [7]

X = 4

7(4)+14-3(4)=30

7(-11)+14-3(-11)=-30

So, 4 is the answer because when substituted for X, it gives you 30.

Find the time required for an investment of $3000 to grow to $9000 at an interest rate of 6.5% per year, compounded quarterly. (

Vanyuwa [196]

Answer:

$t=17.04\ years$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$P=\$3,000\\A=\$9,000\\ r=6.5\%=6.5/100=0.065\\n=4$

substitute in the formula above

$9,000=3,000(1+\frac{0.065}{4})^{4t}$

solve for t

Simplify

$3=(1.01625)^{4t}$

Apply log both sides

$log(3)=log[(1.01625)^{4t}]$

Apply property of logarithms

$log(3)=(4t)log(1.01625)$

$t=log(3)/[4log(1.01625)]$

$t=17.04\ years$
