There 400 students in sixth grade of these students 180 are boys what percent of sixth graders are girls.

1 answer:

7 0

To solve this, you need to subtract 180 from 400: (400-180=220). After that (I used the fraction/proportion/variable way, but there are others), so 220/400=%(p)/100. Multiply diaganolly, so 400*p=400p, which is equal to 220*100=22000. Therefore, 400p=22000. Now, you have to isolate the variable by dividing both sides by 400: 400p/400=p, and 22000/400=55. Therefore, p=55, or %=55, so the answer is 55%, or C.

Solve the equation -25p – 2 = 48 for p. A. -2 B. 1 C. 3 D. 8

konstantin123 [22]

Answer:

A. -2

Step-by-step explanation:

-25p - 2 = 48

First, add 2 to both sides

That gives you

-25p = 50

Then, divide both sides by -25. Then that leaves the answer.. p = -2

Megan is sitting in her car in a parking lot. The car next to her pulls forward. If Megan is looking only at the car next to her

Zina [86]

Answer:Backward

Step-by-step explanation:

If the car next to Megan is being Pulled Forward and Megan is seeing only the pulled car then her car appears to be moving backward.

This can be said by using the concept of relative velocity which states that the speed of the body with respect to the other is considered to be at rest.

Here Megan's car appears to move backward with respect to the car next to her due to the existence of relative velocity.

Answer:

7.(1,0) and (-4,0)

8. (-3,0) and (-2,0)

Step-by-step explanation:

When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are 1 and -4

(1,0) and (-4,0)

8. When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are -3 and -2

(-3,0) and (-2,0)

Step-by-step explanation:

In parallelogram, opposite sides are parallel and equal

3x + 7 = 5x -17

3x - 5x = -17 - 7

-2x = - 24

x = -24 /-2

x = 12

5) A positive plus a negative will (always, sometimes, never) be negative.

GREYUIT [131]

Hello logan693616!

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

A positive plus a negative will (always, sometimes, never) be negative.

Give an example that proves your answer:

$\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}$

A positive plus a negative will sometimes be negative.

Suppose, we take a positive number whose value is greater than that of the negative number. While adding them, we'll take the sign of the greater number, which in this case is positive, so our answer will be a positive number. For example, +4 + (-3) = +1.
Now, if we take a negative number which is greater than the positive number, the sum of the two numbers will be negative. For example, (-4) + 3 = -1.
So, the answer can actually depend based on the value of the numbers used.
Hence, our answer is ⇨ A positive plus a negative will sometimes be negative.
