Answer:

1. unknown

2. 1/4h+3

3. a=2

4. x=8

5. p=30

Step-by-step explanation:

32k+24= not sure where you are going with this.

(3/4h+4)-(1/2h+1). you can rewrite it so it shows numbers and variables together.

(3/4h-1/2h) -(4+1).

3/4h-1/2h = 1/4h. &

the subtract changes the plus to minus, so it is 4-1= 3

So, 1/4h+3.

5a-12=-2

you want to have the letter a, by itself on one side of the = sign.

to do that, you need to do the opposite on both sides.

start with -12. (add 12 to both sides)

5a -12 + 12=-2+12

5a=10

then divide both sides by 5

5a/5=10/5

a= 2

-5(x-4)=-30

take -5 times x and -5 times -4

-5x + 20=-30 (when you multiply a negative times a negative, it is a positive. )

opposite to both sides again. -5x+20-20=-30-20

-5x=-40

then divide both sides by -5

-5x/-5=-40/-5

x=8

EXPLAIN HOW YOU WOULD USE REPEATED SUBTRACTION TO FIND 8 DIVIDED BY 2

Zepler [3.9K]

Imagine that you have 8 apples which you want to hand out to 2 people. You want each person to get an equal amount of apples, so you decide to give 2 apples at a time (one apple to each), until you run out or you don't have enough to give each of the 2 people another apple. Notice that each time you give out 2 apples, you have to subtract 2 from the total left over, and each person gets one apple. Let's see what happens:
1. 8-2=6 -- each person now has 1 apple, and there are 6 more to hand out;
2. 8-2-2=4 -- each person now has 2 apples, and there are 4 more to pass out;
3. 8-2-2-2=2 -- each person now has 3 apples, and there are 2 more to distribute;
4. 8-2-2-2-2=0 -- each person now has 4 apples and there are no more apples to pass out.
Then you hand out 8 apples to 2 people and each of the get 4 apples. This meansthat 8÷2=4.

An automobile retailer calculates that its loss on the sale of Type M cars is given by L(50) = 8,000 and L'(50) = −500, where L(

Anika [276]

Answer:

The loss on the sale of 50 type M cars is $8000, and the loss is decreasing at the rate of $500 per 50 type M car sold.

Step-by-step explanation:

Given

$L(50) = 8000$

$L'(50) = -500$

Required

Interpret

From the question, we understand that:

$x \to$ Number of cars

$L(x) \to$ Profit on x cars

Using the above as a point of reference,

$L'(x) \to$ Rate of loss per x cars

So, the interpretations are:

$L(50) = 8000$

A loss of 8000 on 50 cars

$L'(50) = -500$

The loss rate is a reduction of 500 per 50 car

A conical paper funnel of radius 4 and height 6 units is needed to make a good cup of coffee. If this funnel is made out of a se

Nimfa-mama [501]

Answer:

The radius of this circle is $2\sqrt{13}$ and the central angle of the sector is $\theta=\frac{2}{\sqrt{13}}\times360^\circ$ .

Step-by-step explanation:

Consider the provided information.

If a conical paper funnel is made out of a sector of circle then the radius of the sector becomes the slant height of the cone, and the length of the curved part of the sector becomes the circumference of the base of the cone.

First find the slant height: $l=\sqrt{r^2+h^2}$
