Answer:

The answers are \(\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},\) and \(\frac{10}{1}\).

Step-by-step explanation:

Proportions are fractions that can be made by using the given numbers, which in this case are 2, 5, 8, and 20. Let's pair each one with the other three and then simplify if possible.

First, let's begin with 2:

\(\frac{2}{5} = \frac{2}{5}\)

\(\frac{2}{8} = \frac{1}{4}\)

\(\frac{2}{20} = \frac{1}{10}\)

Then, let's do 5:

\(\frac{5}{2} = \frac{5}{2}\)

\(\frac{5}{8} = \frac{5}{8}\)

\(\frac{5}{20} = \frac{1}{4}\)

Note that we already have \(\frac{1}{4}\), so we do not need to include an additional one.

Now, let us do 8:

\(\frac{8}{2} = \frac{4}{1}\)

\(\frac{8}{5} = \frac{8}{5}\)

\(\frac{8}{20} = \frac{2}{5}\)

See how we already have \(\frac{2}{5}\), so we won't have to include that as well.

Finally, let's do 20:

\(\frac{20}{2} = \frac{10}{1}\)

\(\frac{20}{5} = \frac{4}{1}\)

\(\frac{20}{8} = \frac{5}{2}\)

Now see that we already have both \(\frac{4}{1}\) and \(\frac{5}{2}\), so we won't have to include both of them, as they are both extras.

Hence, the answers are \(\frac{2}{5}, \frac{1}{4}, \frac{1}{10}, \frac{5}{2}, \frac{5}{8}, \frac{4}{1}, \frac{8}{5},\) and \(\frac{10}{1}\).

To convert the fraction 2/4 to a decimal, we can perform the division 2 divided by 4 using long division or mental math.

2 ÷ 4 = 0.5

Therefore, 2/4 as a decimal is 0.5.

Answer:

Following on from step 3

0 = (x + 1)(x + 3)

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values into either of the 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1 : y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3 : y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Step-by-step explanation:

The solutions that represents the system of the equation are (- 3, 5 ) and (- 1, 9 )

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

0 = (x + 1)(x + 3)

By equating each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

Substitute these values in 2 equations for the corresponding value of y

using y = 2x + 11

x = - 1

y = - 2 + 11 = 9 ⇒ (- 1, 9 )

x = - 3

y = - 6 + 11 = 5 ⇒ (- 3, 5 )

Therefore, the solutions are (- 3, 5 ) and (- 1, 9 )

Answer:

256

Step-by-step explanation:

4*4*4*4

The solution of the expression 4⁴ is 256.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

A phrase: 4 Superscript 4

A phrase can be expressed as 4⁴.

That means,

4⁴ = 256.

Therefore, solution is 256.

Answer:

8.12

Step-by-step explanation:

Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.

We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:

A =P \((1 + r/n)^_(nt)\)

where:

A is the amount of money in the account at the end of the period

P is the principal (initial amount) in the account

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the time (in years)

We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:

A = \($500(1 + 0.075/12)^_{(12*(9/12))\) = \($532.72\)

Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

Answer:

A: 4

Step-by-step explanation:

So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)

Then simplify the terms so you end up with (4)(64) / (32) (2)

Then multiply the denominator so you end up with (4) (64) / (64)

Since both the denominator and numerator have 64, those cancel out leaving you with 4

Step-by-step explanation:

a. -11r ≥ 220

Divide both sides by -11 to isolate r.

r ≥ -20

b.

-8 ≤ -7 + (x/10)

Add 7 to both sides.

-1 ≤ x/10

Multiply both sides by 10 to cancel out the denominator of x.

-10 ≤ x

c. -1 - 6(5q - 2) ≥ -139

Distribute the -6 across the parentheses.

-1 - 30q + 12 ≥ -139

Combine like terms on the left side.

-30q + 11 ≥ -139

Subtract 11 from both sides.

-30q ≥ -150

Divide both sides by -30 to isolate q.

q ≥ 5

Answer:

No, both televisions are not similar.

Aspect ration 12:9 is similar to 4:3

Step-by-step explanation:

Lets consider it this way.

Aspect ration can be defined as a ratio of width to height.

For a television with aspect ratio 4:3

\(3-4=1\\\frac{1}{3}\cdot100=33\%\)

which means that the width will always be 33% greater than the height, which will result in a boxy image.

For a television with aspect ratio 16:9

16 - 9 = 7

\(\frac{7}{9}\cdot100=78\%\)

which means that the width will be 78% greater than the height, which will result in a rectangular image.

Hence, both are not the same.

Exact similar dimension to that of 4:3 can be 12:9 because in both, width is 33% greater than height

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

The answer would be 12 because a dice has 6 sides and you have 2 of them
