The school you want to go to has an acceptance rate of 15% 15%. That means that 15% 15% of the students who apply to the school get in. The school took in 1800 1800 students last year. How many students applied?

Answers

Answer 1
Answer: n x 0.15 = 1800
n = 1800 / 0.15
n = 12,000

Therefore 12,000 students applied for the school.

NEED HELP!A.Yes, Francisco made a reasonable amount because he made 1.5 L more so he had 6 L of juice (4.5 + 1.5 = 6).B.No, Francisco did not make a reasonable amount because he needed a total of 10.5 L (4.5 + 6 = 10.5).C.No, Francisco did not make a reasonable amount because he needed a total of 7.5 L of juice (6 + 1.5 = 7.5).

What is the next number in this pattern?4,16,64,256,_

A 260
B 448
C 504
D 1024

Answers

The answer to the question is B

Answer: D

Step-by-step explanation: Its multiplying by 4 so 4X16 equals 64, and 64X4 equals 256 so 256X4 equals d 1,024.

What precent does this change $16 to $4

Answers

Answer:

Percentage change=75% .

Step-by-step explanation:

Given : $16 to $4    

To find:  What is the percent change .

Solution: We have given that   $16 to $4  .

Change = final value - initial value .

Change   = $16 - $4 

                  =$12

percentage change = (change)/(original value) *100

                               =    (12)/(16) *100

On dividing both number by 4

percentage change=. (3)/(4) *100

percentage change=. [tex]\frac{300}{4} .

percentage change=75% .

Therefore, percentage change=75% .
The percent change is 25%,because 4 divided by 16 is 0.25,and to convert a decimal to a percent,I multiplied 0.25 by 100,and the product,(the answer when 2 or more numbers are multiplied)was 25 and then i added the percent sign to 25,and so the percentage is 25%

Choose the equation that represents a line that passes through points (−6, 4) and (2, 0). x + 2y = 2 2x − y = −16 x + 2y = −8 2x + y = 4

Answers

Answer:

x + 2y = 2

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

================================================

We have the points (-6, 4) and (2, 0).

Substitute:

m=(0-4)/(2-(-6))=(-4)/(8)=-(1)/(2)

Put the value of the slope and coordinates of the point (2, 0) to the equation of a line:

0=-(1)/(2)(2)+b

0=-1+b          add 1 to both sides

1=b\to b=1

The equation of a line in the slope-intercept form:

y=-(1)/(2)x+1

Convert to the standard form Ax+By=C

y=-(1)/(2)x+1           multiply both sides by 2

2y=-x+2             add x to both sides

x+2y=2

Answer:

Option 1.

Step-by-step explanation:

It is given that the line passes through the points (-6,4) and (2,0).

If a line passes through two points, then the equation of line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

Using the above formula the equation of line is

y-(4)=(0-4)/(2-(-6))(x-(-6))

y-4=(-4)/(8)(x+6)

y-4=(-1)/(2)(x+6)

Muliply both sides by 2.

2y-8=-x-6

x+2y=-6+8

x+2y=2

Therefore, the correct option is 1.
