Answer:

B. Sometimes.

Step-by-step explanation:

We have been given a statement. We are asked to choose the option that is true for our given statement.

Statement:

If angles are supplementary, then one of the angles is an obtuse angle.

A. Always.

We know that two 90 degree angles are supplementary to each other. We know that a right triangle is not an obtuse angle, therefore, option A is not a correct choice.

B. Sometimes.

Since supplementary angles are not necessarily right angles always, one angle could be obtuse and one could be acute, therefore, option B is the correct choice.

C. Never.

We know that when an obtuse angle and an acute angle add up-to 180 degrees, they are supplementary, ex- $120^{\circ}, 60^{\circ}$ .

Since 180 degrees is an obtuse angle, therefore, option C is not a correct choice.

If a mechanic uses his credit card to pay for a compressor that costs $477.95 and does not pay on it until the second month, wha

Answer:

A. $7.17

Step-by-step explanation:

We have been given that a mechanic uses his credit card to pay for a compressor that costs $477.95 and does not pay on it until the second month.

We will use compound interest formula to solve our given problem.

$A=P(1+\frac{r}{n})^{nT}$ where,

A = Final amount after T years,

P = Principal amount,

r = Annual interest rate in decimal form,

n = Periods of compounding,

T = Time in years.

Let us multiply our given rate by 12 to get APR and convert it in decimal form.

$APR=12\times 1.5\%$

$APR=18\%$

$18\%=\frac{18}{100}=0.18$

Since 1 year equals 12 months, so 1 month will be 1/12 year.

Upon substituting our given values in above formula we will get,

$A=477.95(1+\frac{0.18}{12})^{12\times\frac{1}{12}}$

$A=477.95(1+0.015)^{1}$

$A=477.95(1.015)$

$A=485.11925$

Now let us subtract principal amount from the final amount to get the monthly interest charge at the end of 1st month.

$\text{The monthly interest charge be at the end of the first month}=485.11925-477.95$

$\text{The monthly interest charge be at the end of the first month}=7.16925\approx 7.17$

Therefore, the monthly interest charge be at the end of the first month will be $7.17 and option A is the correct choice.

FIRST PERSON TO ANSWER THIS CORRECTLY WILL BE MARKED BRAINIEST

erma4kov [3.2K]

Answer:

m<ZXY - m<WXZ = m<WXY 

Step-by-step explanation:

given:

point Z is in the interior of <WXY creating XZ.

if m<WXZ = 20

m<WXY = 100

find:

what would equation would you set up to find the missing angle measure?

solution:

Since Z is interior of <WXY

m<ZXY - m<WXZ = m<WXY

<WXY = 100 - 20 = 80°

therefore, the equation would be m<ZXY - m<WXZ = m<WXY

Determine the next term in the geometric sequence. -1, -6, -36, -216, ??

nordsb [41]

You are multiply by 6 each time.

The next term is -216 x 6

-216 x 6= -1296

-1296 is your answer
