Answer - Part A:

I would say "whole".

Step-by-step explanation:

So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.

Where, the original price is the total price. So, the means that it is the whole price.

Just to help:

Answer - Part B: The original cost of the jeans are $80.

Step-by-step explanation:

If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.

So, see? 30% of 80 is $24.

(This can also be used to show your work)

Hope this helps! :)

V=s^2+1/2sh solve for h

wariber [46]

First, you separate the h variable by subtracting s^2 on both sides of the equation, getting
V - s^2 = sh/2
Then, all you have to do is divide both sides by s/2, so you get
h = 2*(v - s^2)/s as your final answer.

How many solutions does the following equation have? -4(+5) = -4- 20

Rus_ich [418]

Answer:

Step-by-step explanation:

Try looking at it in 2 ways- left side and right side. On the left side we have -4*5, which equals -20. On the right we have -4-20, which equals -24. so then when we add it all together (not literally) we get -20=-24. Since -20 and -24 obviously do not equal eachother, there is no solution.

Let x be the length of each side

Turn it into an algebraic expression: $x^{2} = 196$
14 × 14 = 196
So, x = 196

Sketch one cycle of the cosine function y= cos 2θ

Liula [17]

Based on function transformations, the graph of y= cos(2θ), is the same as the graph of y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs

well the period for this function will then be $\bf \cfrac{2\pi }{B}\iff \cfrac{2\pi }{2}\implies \pi$

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally

4 (negative one-half x + 7) + 5 x = 15

Ronch [10]

Answer:

Step 3 is incorrect

Step-by-step explanation:

4(-1/2x + 7) + 5x = 15

-2x + 28 + 5x = 15

3x + 28 = 15

3x + 28 - 28 = 15 - 28

3x = -13
