If 28% of a sum is 100.80 what is the sum

Answers

Answer 1

Answer: $360.00*.28= 100.80

Or do a portion

28%/100%=100.8/x

Then cross multiply

10080=28x

x=360

A. $1.500 × 12

Step-by-step explanation:

Since there are 12 months in a year, we need to multiply $1,500 by 12. To make this easy, I'll show the progression from month to month.

Multiplying is simply adding the same number a given number of times, in this case, 12. Here is a visual representation of multiplication.

1st month $1,500

add $1.500, result is same as $1,500 x 2

2nd month $3,000

add $1.500, result is same as $1,500 x 3

3rd month $4,500

add $1.500, result is same as $1,500 x 4

4th month $6,000

add $1.500, result is same as $1,500 x 5

5th month $7,500

add $1.500, result is same as $1,500 x 6

6th month $9,000

add $1.500, result is same as $1,500 x 7

7th month $10,500

add $1.500, result is same as $1,500 x 8

8th month $12,000

add $1.500, result is same as $1,500 x 9

9th month $13,500

add $1.500, result is same as $1,500 x 10

10th month $15,000

add $1.500, result is same as $1,500 x 11

11th month $16,500

add $1.500, result is same as $1,500 x 12

12th month $18,000

What system of inequalities is graphed below?

Answers

Answer:

Equations are y > x² - 4 and y < x² + 6.

Step-by-step explanation:

Given : Graph with two parabola.

To find : What system of inequalities is graphed below.

Solution : We have given graph

We can see from the given graph both are dotted line that mean it does not have equal sign .

We can see graph with vertex ( 0 , -4 ) are shaded up ( grater than sign ) that mean equation would be

y > x² - 4.

For upper parabola vertex is ( 0 , 6) and shaded down( less than sign) that mean equation

y < x² + 6.

Therefore,Equations are y > x² - 4 and y < x² + 6.

$y\geq x^2-4-blue\n\ny < x^2+6-red\n\nAnswer:\text{I think is D.}\ny\geq x^2-4\ny < x^2+6$

which of the following is an equation of a line parallel to the equation $y=(1)/(2) x+1$

Answers

Answer:

Any equation of a line having a slope of 1/2.

Step-by-step explanation:

It appears that the question gives answer choices and this problem could have many solutions, but parallel lines have equal slopes. The slope of this line is 1/2 since it is in y=mx+b form where m is the slope. So a few examples of equations of lines parallel to the given equation would be y = 1/2x - 5 or y = 1/2x + 10 etc.

RATIOS Pat's Flower shop sells 2 daisies for 1.50

a) How much would 7 daisies cost?

b) How many daisies can you get with 8.25?

Answers

You have to do unit rates. whats 1.50 divided by 2 which is 1.25. with this you can multiply it by seeven or divide it by 8.25. remember 1 daisy cost $1.25 :) hope this helped. and to one of my causes, rebel against favoritism at home and at school :)

Radius: 12
diameter: 24 inches
circumference:
area:

Answers

The formula for the area of a circle is $\pi r^(2)$

To break it up, its π×r×r=A

The radius is 12inches

So the equation is 3.14×12×12

3.14×12=37.68

37.68×12=452.16

452.16 rounded is 452

A=452inches
