What percent of 67 is 33? Round to the nearest tenth of a percent

Answers

We will make a proportion:
67 : 33 = 100 : x
67 x = 33*100
67 x= 3300
x= 3300/97= 49.2537
Round to the nearest tenth:
Answer: 49.3%.

A company has a policy making the compensation of its CEO proportional to the dividends that are paid to shareholders. If the dividends increase from $72 to $80 and the CEO’s compensation is increased from $360,000 to $420,000, was the company’s policy followed? yes or no

Answers

Percentage increase of dividends:
[(80-72)/72] x 100 = 11.1% increase

Percentage increase of CEO compensation:
[(420000-3600000/3600000] x 100 = 16.67% increase

Therefore the company policy was not followed as the CEO's compensation had a greater percentage increase than the dividends to the shareholders

What is 5(x+8)=7x+38
Simplify your answer as much as possible

Answers

Answer:

5*(x+8)-(7*x+38)=0

5 • (x + 8) - (7x + 38) = 0

2 - 2x = -2 • (x - 1)

-2 • (x - 1) = 0

-2 = 0

This equation has no solution.

An odd number on a spinner with equal sized sections labeled 1-8A. a number less than 4
B. a number greater than 4
C. a multiple of 3
D. an even number

Answers

probability is
(desired outcomes)/(total possible outcomes)
total possible is 8 since 8 total spaces

A. number les than 4, there are 3 numbers (1,2,3) so
3/8 os probability

B. number greater than 4, ther are 4 (5,6,7,8), so 4/8=1/2 is probability

C. multiplule of 3, there are 2 (3,6) so 2/8=1/4 is probability

D. even number, there are 4 (2,4,6,8) so 4/8=1/2 is probability

A. 3/8
B. 1/2
C. 1/4
D. 1/2

What will be the linear equation for the shown table?

Answers

Answer:

y=2x+5

Step-by-step explanation:

To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)

So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2

Slope = 2, now find b

So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5

Put it all together y = 2x + 5
