Answer 1

Answer: T(n)=2n+3
it is easy :) you should just plug in 3 to the n and it is the answer :)

T(3)=2×3+3
=9 IT IS THE ANSWER
hope you understand it!

Answer 2

Answer: $T(3)=2\cdot3+3=6+3=9$

Adam wants to buy a video game system that costs $100.00. He has $28.35 in one piggy bank and $31.90 in another piggy bank. How much more money does Adam need before he can buy the video game system? How can estimation be used to make sure the answer is reasonable?

A.
Answer: Adam needs $160.25 more.
Estimation: $28 + $32 = $60.
$100 + $60 = $160.
Adam needs about $160 more to buy his video game system.

B.
Answer: Adam needs $39.75 more.
Estimation: $28 + $32 = $60.
$100 – $60 = $40.
Adam needs about $40 more to buy his video game system.

C.
Answer: Adam needs $30.13 more.
Estimation: $28 + $32 = $60.
$60 ÷ 2 = $30.
Adam needs about $30 more to buy his video game system.

If 3 dice are rolled at the same time, what is the probability of all 3 dice showing even facevalues? (i.e. all 3 dice showing 2, 4, or 6)

Answers

Total possible outcomes of 3 dice = 6 x 6 x 6 = 216

Total number of ways for all 3 to show even numbers:
222
224
226
242
244
246
262
264
266
.
.
etc. There 27 of them.

Probability = 27 / 216 = 1/8 = 12.5 percent .

A pool shaped like a rectangle prism is 40 feet long 20 feet wide and 4 feet deep attached to the side of the pool is a hot tub with 1/4 the volume of the pool what is the total volume of the pool and hot tub?

Answers

V=legnth times width times height
pool=40 by 20 by 4
pool=40 times 20 times 4
pool=3200 ft^3
hot tub is 1/4 of pool
hot tub=1/4 times 3200=800

total is pool+hot tub=3200+800=4000 ft^3

What values of x make the equation x^2 + 9x – 22 = 0 true? Check all that apply.–11

–2

0

2

11

Answers

If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:

x^2 + 9x - 22 = 0
(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11

The correct result would be x = 2 and x = - 11.

Answer:

x = 2 , - 11.

Step-by-step explanation:

Given : x² + 9x – 22 = 0

To find : What values of x make the equation.

Solution : we have given x² + 9x – 22 = 0

On factoring

x² + 11x - 2x – 22 = 0 .

Taking common x from first two term and -2 from last two terms.

x ( x +11) - 2 (x +11) = 0.

On grouping

(x -2) (x +11) = 0

For

x - 2 =0

x = 2 .

For

x + 11 = 0

x = -11.

Therefore, x = 2 , - 11.

How would I do this problem. It says to solve and check 5/k? -6?= -3

Answers

You would first move the 6 onto the other side by adding it. Then you would end up doing -3+6 which is 3. Then your equation will look like: 5/k=3. You would then do opposite operation again to the 5 this time. You do the opposite of dividing, so multiplying. You multiply the 5 on both sides which you would end up doing 5 x 3 which is 15. Your equation will then be looking like k=15. To check if you did it right, just simply plug in the 15 as k. So the equation to check should look like this: 5/15-6=3. Solve it, and you should end up as the answer being equal to 3.
