Answer:

55%

Step-by-step explanation:

For percentages, you need to divide the part by the whole, then multiply by 100.

In this case, [tex]\frac{22}{40}[/tex] = 0.55.

Then multiply by 100 to get a percentage: 0.55 x 100 = 55%

Answer:

55%

Answer:

First Question = 16 Second Question = 8

Step-by-step explanation:

First one

32+48=x(2+3)

80=5x

Divide each sides with 5 and you have x=16

Second one

32+48=4(x+12)

80=4x+48

subtract 48 from 48 and 80 and you have 32=4x.

Divide it with 4 both side and you have x=8

Answer:

16b^4-9

Step-by-step explanation:

Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9

Answer:

[tex]16b^4-9[/tex]

Step-by-step explanation:

When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).

For [tex](t_1+t_2)(t_3+t_4)[/tex], let:

[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]

In the FOIL method, the steps go:

[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]

Given [tex](4b^2+3)(4b^2-3)[/tex], we have:

[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]

Combine like terms:

[tex]\boxed{16b^4-9}[/tex]

Answer:

  5

Step-by-step explanation:

The volume of a right square pyramid is given by the formula ...

  V = 1/3Bh

where B is the area of the base.

The volume of the larger pyramid will be ...

  V' = 1/3(5B)h

So, the ratio of volumes is ...

  V'/V = (1/3(5B)h)/(1/3Bh)

  V'/V = 5

The ratio of volumes is 5.

Answer:

2y+5

Step-by-step explanation:

Lets start with an expression for how many yards Gary threw. Since y is the variable given in the problem, we'll use that.

Yards Gary threw = y

We also know that Pat threw 5 more than twice the yards Gary did. First, we multiply Gary's yards by 2, then add 5 more. We end up with the expression:

Yards Pat threw = 2y+5

Part A: Garcia mixed 4 cups of red with 1 cup of yellow.

Part B: 1/4 because 4 cups of red requires 1 cup of yellow, so 1 divided by 4 is 1/4.

Part C: $7

Hope this helps! :)

The unit price for a cup of red paint is equal to $7

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: The ratio of the number of cups of red paint to the number of cups of yellow paint that Garcia mixed to make a shade of orange paint is 4:1

For every yellow cup of paint Garcia mixed 4 cups of red paint to the mixture.

Now the ratio given here is  4:1

Thus for every 1 cup of yellow paint garcia mixes 4 cups of red paint

or for 1 cup of red paint garcia mixes 1/4 cup of yellow paint to the mixture.

Because 1:4=1:1/4

Now in a shade of orange paints there are 4 cups of red paint and 1 cups of yellow paint thus total cups of paint=5

Now 6 cups of red paint cost $42

Thus 1 cup of red paint is equal to 42/6=$7

Thus cost of each red paint is equal to $7

Hence, The unit price for a cup of red paint is equal to $7

Answer:

short base: 6 yards

long base: 8 yards

Step-by-step explanation:

Our understanding of your figure is shown below.

The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."

The short base is 6 yards.

__

The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.

The long base is 8 yards.

Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.

Answer:

Volume: 864

Surface Area: 684

Step-by-step explanation:

Volume:

[tex]\frac{1}{2}(9 * 16 * 12) = 864[/tex]

Surface-Area: (Pretty Self-explanatory)

1. Triangles - 12 * 9 = 108 (You don't need to divide it by two, just leave it as is because there are two of these triangles.)

2. Base - 16 * 9 = 144

3. Height/Base - 12 * 16 = 192

4. 15 * 16 = 240

192 + 144 + 108 + 240 = 444

The Surface Area is 684.

Answer:

12x + 8 = 12 x 6 + 8 = 80

8x-3 = 8 x 6 - 3 = 44

Step-by-step explanation:

(12x+8) + 55 + (8x-3) = 180 (Angle Sum Property)

(8+55-3) + (12x + 8x) = 180( group the variables)

(60) + (20x) = 180

20x = 180 - 60

20x = 120

x = 120/20 = 6

x=6

|a| represents Absolute value, it is the distance from zero that a number is on the number line. And we know distance cannot be negative.

So,

[tex]|-a| = a\\\\| \frac{-a}{b}| = \frac{a}{b}\\\\|\frac{a}{-b}| = \frac{a}{b}[/tex]
