Answer:

0.6 inch

Step-by-step explanation:

The volume of a sphere is calculated through the equation,

V = 4πr³/3

Which means that the radius is calculated by the equation,

(3V/4π)^(1/3) = r

Substituting,

Sphere A, (3x30/4π)^(1/3) = r = 1.927 in

Sphere B, (3x10/4π)^(1/3) = r = 1.336 in

When we subtract the radius, we get an answer of 0.59 inch. Therefore, the answer to this item is approximately 0.6 inch.

Beyonce is solving a system of equations: 2x – 3y = -2
4x + y = 24

She decides to use the elimination method to find the solution. She multiplies the second equation by 3 and adds it to the first equation to find 14x = 70, showing her that x = 5. Beyonce finds that y = 4.

Step 3: 4x + y = 24

4(5) + y = 24

20 + y = 24
-20 -20

y = 4

Step 1: 3(4x + y = 24) → 12x + 3y = 72
Step 2: 2x – 3y = -2
Solution: (5, 4)

+ 12x + 3y = 72
14x = 70

→ x = 5

Thinking about this process, Beyonce says out loud, “There are lots of ways I could go about solving this problem. I could do the method above or I could multiply the first equation by -2 and add the second.

Step 3: 4x + y = 24

4x + 4 = 24
-4 -4

4x = 20

x = 5

Step 1: -2(2x – 3y = -2) → -4x + 6y = 4
Solution: (5, 4)

Step 2: -4x + 6y = 4
+ 4x + y = 24
7y= 28

→ y = 4

“I seem to find that there is only one solution to the two equations, but I wonder if I will get the same solution if I use a different method?”

If Beyonce uses a different method, would she get the same solution? Be sure to show work or explain your reasoning.

Dee's solution is incorrect because her equation is incorrect. Write the correct equation she could use to find x

mx + 40 + 60 = 180
mx + 100 = 180
mx = 180-100

mx = 80

Answer:

21°

Step-by-step explanation:

We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.

5x+6=16x-27

Continue to solve . . .

33 = 11x

x=3

Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get

(16 x 3) - 27, which is equal to 21°.

A loan of $2,000 dollars is being paid off over time. You have automatic payments set up to pay $50 towards the loan each month. You also work and save money in your bank account. You currently have $500 in the bank and save an additional $100 per month. What is the earliest you could pay off you loan?

Answers

Answer:

10 months

Step-by-step explanation:

2000 - 500 = 1500.

You can pay 100 + 50 = 150 per month

1500 / 150 = 10 months

108 degrees

Step-by-step explanation:

Given the following angle measures in triangle QRS

m<Q = 1x

m<R = 3x

m<S = 6x

Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees

The sum of angle in a triangle is 180 degrees

m<Q + m<R + m<S = 180

1x + 3x + 6x = 180

10x = 180

x = 180/10

x = 18

The obtuse angle is 6x

Measure of the obtuse angle = 6x

Measure of the obtuse angle = 6(18)

Measure of the obtuse angle = 108 degrees

Hence the measure of the obtuse angle is 108 degrees
