The table shows the results of a spinner with four colored sections. Use the table to answer the question.The spinner is spun 50 more times. Which is the best prediction for the number of times the spinner will stop on white? A)5

B)10

C)25

D)40

I would have to say b because you have 4 colors and there are a total of 50 spins and each color has a possible chance of each color getting landed on 12.5 times each spin

You have already read 117 pages of a book. You are one third of the way through the book. Write and solve an equation to find the number of pages in the book.

So if 117 pages equals 1/3 of the book then you have 351 pages in the book so... 1/3 x 117 = 351 or 351 / 1/3 = 117

What is the common difference for the arithmetic sequence?

4.7, 6, 7.3, 8.6, 9.9, …

The common difference of th AP will be 1.3.

What is the formula to calculate the nth term of an Arithmetic Sequence ?- The formula to calculate the nth term of an Arithmetic Sequence is aₙ = a + (n - 1)d

- The common difference [d] can be obtained as → d = a – a₁ = a₃ – a₂ or d = aₙ – aₙ ₋ ₁

- The Arithmetic Sequence can also be written in terms of common differences → a, a + d, a + 2d, a + 3d, a + 4d.

- The sum of [n] terms of an Arithmetic sequence will be :

Sₙ= n/2[2a + (n − 1) × d]

We have the arithmetic sequence as -

4.7, 6, 7.3, 8.6, 9.9, …

The common difference of th AP will be -

d = 6 - 4.7

d = 1.3

Hence, the common difference of th AP will be 1.3.

Jake earned $430 in interest on a $2500 investment after 18 months. What was the annual interest rate? (round to the nearest whole percent)

I=PRT

I=interest

P=principal=investment

R=rate in decimal

T=time in years

remember 12 months per year

given

I=430

P=2500

R=?

T=18/12 years=1.5years

430=2500 times r times 1.5

430=3750r

divide both sides by 430

0.1146666=r

11.4666%

PLEASE ANSWER ASAP!!!!!!!!!!!!!!! The perimeter of a rectangle is at most 80 inches. The length of the rectangle is 25 inches. The inequality 80 - 2w > 50 can be used to find w, the width of the rectangle in inches. Solve the inequality and interpret the solution. How will the solution change in the width must be at least 10 inches and a whole number?

Answer:

(1). The solution of inequality is 15>w. It means the width of the rectangle is less than 15 inches.

(2) The solution set is w={10,11,12,13,14}.

Step-by-step explanation:

The given inequality is

50" alt="80-2w>50" align="absmiddle" class="latex-formula">

where, w is the width of the rectangle in inches.

Add 2w on both sides.

50+2w" alt="80-2w+2w>50+2w" align="absmiddle" class="latex-formula">

50+2w" alt="80>50+2w" align="absmiddle" class="latex-formula">

Subtract 50 from both sides.

50+2w-50" alt="80-50>50+2w-50" align="absmiddle" class="latex-formula">

2w" alt="30>2w" align="absmiddle" class="latex-formula">

Divide both sides by 2.

w" alt="\frac{30}{2}>w" align="absmiddle" class="latex-formula">

w" alt="15>w" align="absmiddle" class="latex-formula"> ... (1)

The solution of inequality is 15>w. It means the width of the rectangle is less than 15 inches.

The width must be at least 10 inches and a whole number.

.... (2)

Using (1) and (2), we get

Therefore the solution set is w={10,11,12,13,14}.

W=15 Subtract 80 from both sides then you divide by -2w.

I don’t know this question

I don't see an extraneous value there, -7 checks out well if you plug it in the original equation, and so does 3.
