Answer:

x = 3

Step-by-step explanation:

(8x + 4) + (- 11x + 5)

= 8x + 4 - 11x + 5

= 8x - 11x + 5 + 4

= - 3x + 9

- 3x + 9 = 0

- 3x = - 9

x = - 9 ÷ - 3

x = 3

Answer:

No choices, but 3(2x) is simplified to 6x

Step-by-step explanation:

3(2x) = 3 × 2x = 6x

Answer: The expression that is equivalent to (2x)3 is 6

Step-by-step explanation: The answer is 6 because x is equal to 3 so 3*2=6

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.

Answer:

[tex]\frac{2}{3}[/tex]

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:

Yes and no solution :)

Step-by-step explanation:

No explanation needed for the first part.

2 as a fraction is 2/1

So rewrite as 2/1 + 2/1

We can multiply the whole equation by lets say.... 428

Now we have 856/428 + 856/428

Now we can put 0 at the other side of the equation... because... yes

856/428+856/428 = 0

Now lets just move one of these to the other side of the equation :)

856/428 = -856/428

Now I dont know, how about we cancel out the denominators.

856=-856

now if we move the right side back to the left... we get

1712=0

This equation is not true therefor 2+2 has no solution

Answer:

9/16

Step-by-step explanation:

Use the Part = 18, as the numerator and use the Whole = 32, as the denominator. The part-to-whole fraction is 18/32

Meaning:

The Part is 18/32 of the Whole

Reducing the fraction, it is also true that:

The Part = 9/16 of the whole

Answer: 169π

Step-by-step explanation:

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:

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:

Step-by-step explanation:

The yellow rectangle is an enlargement of the blue one, and is a positive dilation.  The blue rectangle is shrunken from the yellow one and is a negative dilation.

Answer:

A = 216.314

C = 52.124

Step-by-step explanation:

We know the radius so now we need to know the diameter. So multiple the radius by 2.

R = 8.3

D = 16.6

Let's find the area first

A = 3.14×r²

A = 3.14×68.89

A = 216.314

Now find the circumference

A = 3.14×d

A = 3.14×16.6

A = 52.124

Answer:

two unequal real roots

Step-by-step explanation:

35 - 5(4)(-3) simplifies to 35 + 60, or 95.

Because the discriminant is positive, the quadratic has two unequal real roots.

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!

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)
