Answer: 90 degrees

============================

Explanation:

Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.

Consequently, we can replace y with x and solve for x like so:

x+y = 180

x+x = 180 .... y is replaced with x since y = x

2x = 180

2x/2 = 180/2

x = 90

This means y = 90 as well. As a check, note how

x+y = 90+90 = 180

which verifies our answer.

Which of the following is equivalent to (5)^7/3

kifflom [539]

The answer is $\sqrt[3]{ 5^{7} }$ 

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical ( $5^{7}$ is called the radicand because it is located in the radical) and the denominator in front of the radical, where it would be called the index.

Here's what a formula would look like: $( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }$

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

The value of the solid's surface area is equal to the value of the solid's volume. Find the value of x.

USPshnik [31]

Volume = (l * w * h) or (11 * 3 * x) which will equal surface area. Volume is 33x for now

Surface Area = 2 (x * 11) + 2 (x * 3) + 2 (11 * 3)

Set Volume equal to surface area. I simplified SA already.
33x = 22x + 6x + 66

33x - 28x = 66

5x = 66

x = 66/5 or 13.2

What are the slope and y-intercept for the graph of y – 3x = -1?

Liula [17]

Answer:

Slope (m) = 3, y-intercept (b) = -1

Step-by-step explanation:

First, we need to write the equation in y = mx + b.

To do this, add 3x to both sides.

y = 3x - 1 is your result.

Now, we have everything we need to do determine our slope and y-intercept in just this equation alone.

Remember, m = slope and b = y-intercept.

In this equation:

m = 3

b = -1

So your slope is 3, and your y-intercept is -1

Answer:

The graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.

Step-by-step explanation:

This can be determined using the formula for calculating the future value (FV) formula as follows:

FV = PV * (1 + r)^n ................................. (1)

Where;

FV = Future value or the amount the graduate will have at end of 36 months = ?

PV = Present value or the total amount invested = Cash gifts from friends and relatives + Amount of 3 scholarships he received = $900 + $250 + $300 + $1,400 = $2,850

r = daily interest rate = 1% / 360 = 0.01 / 360 = 0.0000277777777777778

n = number of days = 36 months * 360 days = 12,960

Substituting the values into equation (1), we have:

FV = $2,850 * (1 + 0.0000277777777777778)^12,960

FV = $2,850 * 1.43332224806396

FV = $4,084.96840698229

Approximating to the nearest cent as required, we have:

FV = $4,084.97

Therefore, the graduate will have $4,084.97 when he cashes in the CD at the end of the 36-months.
