75 students decreased by 80%. Help plz:///

Answers

So,

75 students decreased by 80%. That means that 100 - 80 = 20% remain.

To find 20% of 75 students, just find 10%, which means simply moving the decimal point one place to the left.

75 --> 7.5 = 10% of 75

Therefore,
15 = 20% = 75 because 7.5 * 2 = 15

There are 15 students left.

Terribly sorry if i am wrong.. I believe it would be about 40%

What is an equation of the line that passes through point (8,0) and is parallel to the line x+y=5

Answers

The required equation of the line is y = 8 - x.

Given that,
To determine an equation of the line that passes through the point (8,0) and is parallel to the line x+y=5

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Given equation,

x+y=5
y = -x + 5
m = -1
Since the slope of parallel lines are equals.
So the equation of the line is given as, which is passing by (8,0)
y - 0 = -1 (x - 8)
y = 8 - x

Thus, the required equation of the line is y = 8 - x.

Answer:

y = -x + 5

y - 0 = - (x - 8)

y = -x + 8

Step-by-step explanation:

Lynne bought a bag of grapefruit, 1 and 5/8 pounds of apples, and 2 and 3/16 pounds of bananas. The total weight of her purchases was 7 and 1/2 pounds. How much did the bag of grapefruit weigh?

Answers

The answer would be 3 and 11/16.
First add the 1 and 5/8 to 2 and 3/16.
Subtract this sum from the total 7 1/2 pounds. This will give the weight of grapefruit.

Let, the weight of Grapefruit = x
It would be: x + 1 5/8 + 2 3/16 = 7 1/2
x + 13/8 + 35/16 = 15/2
16x+26+35 /16 = 15/2
16x+61/16 = 15/2
2(16x+61) = 15*16
32x + 122 = 240
x = 118/32
x = 3.68
x = 3 11/18 Pound

In short, Your Answer would be 3 11/18 Pound

Hope this helps!
