Answer:

k=45

Step-by-step explanation:

Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that $45+2k+k=180$ . 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have $45+3k=180$ . Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides $45-45+3k=180 -45 \\3k=135$ as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

*will give brainlist**okay so u want to know how much diapers u will use for 3 years basically and then the details to help u ea

pochemuha

ok so divide 1500 by 250 to determine how many boxes you need to by in 1 year

so that equals 6 then you multiply that by $30 to find the total cost of all the diapers per year so the is $180 per year and then multiply that by 3 to find the cost of all 3 years

So the answer is you will spend $540 in total

Answer:

A. $\frac{3}{7}$

Step-by-step explanation:

The given equation is

$3x-7y=14$

We solve for y by subtracting 3x from both sides to obtain;

$-7y=14-3x$

We now divide through by -7 to get;

$y=\frac{-3}{-7}x+\frac{14}{-7}$

This simplifies to;

$y=\frac{3}{7}x-2$

This equation is now in the form y=mx +c, where $m=\frac{3}{7}$ is the slope.

Find the value of annuity if the periodic deposit is $250 at 5% compounded quarterly for 10 years

mylen [45]

Answer:

The value of annuity is $P_v = \$ 7929.9$

Step-by-step explanation:

From the question we are told that

The periodic payment is $P = \$ 250$

The interest rate is $r = 5\% = 0.05$

Frequency at which it occurs in a year is n = 4 (quarterly )

The number of years is $t = 10 \ years$

The value of the annuity is mathematically represented as

$P_v = P * [1 - (1 + \frac{r}{n} )^{-t * n} ] * [\frac{(1 + \frac{r}{n} )}{ \frac{r}{n} } ]$ (reference EDUCBA website)

substituting values

$P_v = 250 * [1 - (1 + \frac{0.05}{4} )^{-10 * 4} ] * [\frac{(1 + \frac{0.05}{4} )}{ \frac{0.08}{4} } ]$

$P_v = 250 * [1 - (1.0125 )^{-40} ] * [\frac{(1.0125 )}{0.0125} ]$

$P_v = 250 * [0.3916 ] * [\frac{(1.0125)}{0.0125} ]$

$P_v = \$ 7929.9$
