The expression -x^2 + 70x -600 represents a companys profit for selling x items. For which number of items sold is the companys profit equal to zero?

Answer:

Reduction

Step-by-step explanation:

Whenever you see a shape graphed where the points have ' after the letter, then that is the RESULT. So, the yellow parallelogram ABCD is the original, and the blue parallelogram A'B'C'D' is the result, which is obviously smaller than the original. So that means that it's a reduction.

I hope this made sense and helped! :)

Answer:

The number of paperclips decreased by 12.5%

Step-by-step explanation:

72-63=9

9/72 = .125 or 12.5%

Answer:

Step-by-step explanation:

To get percentage change, we use the formula:

Percentage change =

Here,

the new value is the later value of 63 and the old value is the first value of 72

Plugging in the values in the formula gives us:

Percentage change =

The percent change is 12.5% (we can also say that it is a decrease of 12.5% since negative)

Answer:

A: More than half of the scores were 85% or greater.

E: At least one score was exactly 85%

Step-by-step explanation:

Here the 5 test would be taken in science so 85% would be the result of one of the test

Also 85% represent the median so it means there are 2 values more and 2 values less

So there are 3 results with 85% or greater

Hence, the option A and Option E is correc

And, the rest of the options are wrong

Answer:

A and E

Answer:

This is not a right triangle(No)

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

If you use Pythagorean Theorem, you can determine whether or not these measurements make a right triangle. The hypotanuse is always the longest side, or c, in this equation.

a^2+b^2=c^2

14^2+23^2=25^2

196+529=625

725=625

Obviously, this set of measurements do not make a right triangle. Hope this helped!

Question:

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

[tex]Total = (-8) +(-8) +(-8) +(-8)[/tex]

Step-by-step explanation:

Given

[tex]Rungs = -4[/tex] --- It is negative because he is climbing down

[tex]Steps = 8[/tex]

Required

An expression for the number of rungs climbed

To do this, we simply multiply the number of rungs by the steps taken.

[tex]Total = Rungs * Steps[/tex]

[tex]Total = -4 * 8[/tex]

This can be rewritten as:

[tex]Total = -8 * 4[/tex]

The product, when written as sum is:

[tex]Total = (-8) +(-8) +(-8) +(-8)[/tex]

Answer:

In the triangular prism calculator you can easily find out the volume of that solid. A general formula is volume = length * base_area; the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. Our triangular prism calculator has all of them implemented, isn't it awesome?

The specific formulas look as follows:

Length * Triangular base area given triangle base and height

It's this well-known formula mentioned before:

volume = length * 0.5 * b * h

Length * Triangular base area given three sides (SSS)

If you know the lengths of all sides, use the Heron's formula to find the area of triangular base:

volume = length * 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )

Length * Triangular base area given two sides and the angle between them (SAS)

You can calculate area of a triangle easily from trigonometry:

volume = length * 0.5 * a * b * sin(γ)

Length * Triangular base area given two angles and a side between them (ASA)

You can calculate that using trigonometry:

volume = = length * a² * sin(β) * sin(γ) / (2 * sin(β + γ))

Answer:

F = (7,-5)

Step-by-step explanation:

Coordinates are written as:

(x, y)

So the x value, ( the number on the horizontal axis) is 7

The y value, ( the number on the vertical axis) is -5

So lets input.

F = (7,-5)

Answer:

male= 1/3 brown =1/2, both 1/6

Step-by-step explanation:

there is 2 males and 6 total, simplified is 1/3. there are 3 browns and 3 whites, so simplified is 1/2 instead of 3/6. There is only one brown male, so you cannot simplify it more than 1/6.

We are assuming that only one puppy is given away!

Step-by-step explanation:

6 puppies in total

4/6 are female 2/6 are male

2/6 female and brown 2/6 female and white 1/6 male and brown 1/6 male and white

We want all of the male population which is 2/6 and the 2/6 of the female population that are brown added together

[tex]\frac{2}{6} + \frac{2}{6} = \frac{4}{6} = \frac{2}{3}[/tex]

Answer:

21,800

Step-by-step explanation:

Total costs is $16,700 x 4 years = 66,800

He saved 21,000 + receives 24,000 (6,000x4) grants for a total of 45,000 saved.

costs of 66,800 - receipts of 45,000 = 21,800 needed.

Answer:

Step-by-step explanation:

Answer:

A and B (answer #2)

Step-by-step explanation:

right triangles: c^2 = a^2 + b^2

c is the largest side

for A: c = 5, a = 3, b = 4

5^2 = 3^2 + 4^2

25 = 25, so A is a right triangle

for B, c = 13, a = 5, b = 12

13^2 = 5^2 + 12^2

169 = 169, so B is a right triangle

for C, c = 4, a = 2, b = 3

4^2 = 2^2 + 3^2

16 ≠ 13, so C is not a right triangle

So, A and B are right triangles.
