please help I cant get the answer ​

Answer:

15 cm and 25 cm

Step-by-step explanation:

First let's mark the width with the letter b, and the length with a:

width: b

length: a = (2b - 5)

Then we have an inequality (P = 2a + 2b):

2 × (2b - 5) + 2b ≤ 80

4b - 10 + 2b ≤ 80

6b ≤ 80 + 10

6b ≤ 90 / : 6

b ≤ 15

a ≤ 2 × 15 - 5

a ≤ 25

Answer:15 cm and 25 cm

Step-by-step explanation:

The surface area of a solid is the area of its faces. The surface area of a cube is just 6*side length^2 since the faces are the same and the faces are squares. So, we have 6 * 11^2 = 726.

Answer:

complementary

Step-by-step explanation:

if you add angle 1 and 2 they equal 90 degrees that means it's complementary

Answer:

Step-by-step explanation:

To start, we need to recognize that absolute value is a way of expressing the magnitude of a number, regardless of its sign. Thus, to get rid of the absolute value, we need to consider the two cases in which the expression can have either a positive or a negative sign.

For the case of a positive sign, we can simply write the expression as: 14-(x-6)

For the case of a negative sign, we can multiply both sides of the equation by -1 to get: -14 + (x-6)

Overall, we can express the expression without the absolute value symbol as:

14-(x-6) or -14 + (x-6)

Answer:

Each book cost 15 dollars.

Here’s the work: Sara had 136 dollars and spent some money on 8 books. After buying them she had 16 dollars left. So she spent 136 - 16 = 120 dollars on books. Since she bought 8 books with that money, each book cost her 120 / 8 = 15 dollars.

[tex]\large\boxed{\textsf{See Below.}}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked which expressions are equivalent to 10}^{\tt -6}.[/tex]

[tex]\textsf{We are given that we need to use the \underline{Negative Exponent Rule}.}[/tex]

[tex]\large\underline{\textsf{What is the Negative Exponent Rule?}}[/tex]

[tex]\textsf{The Negative Exponent Rule is a rule that describe how to evaluate negative}[/tex]

[tex]\textsf{exponents.}[/tex]

[tex]\large\underline{\textsf{How do we use the Negative Exponent Rule?}}[/tex]

[tex]\textsf{We use the negative exponent rule to multiply the denominator of a number by}[/tex]

[tex]\textsf{itself how many times the value of the exponent is.}[/tex]

[tex]\underline{\textsf{Example of the Negative Exponent Rule;}}[/tex]

[tex]\tt 10^{-2}. \ \textsf{Start with 10}^{\tt 1}, \ \textsf{then continue.}[/tex]

[tex]\tt 10^{1} = \frac{10}{1} \rightarrow 10^{\tt 0} = \frac{10}{1 \times 10} = \frac{10}{10} \rightarrow 10^{\tt -1} = \frac{10}{10 \times 10} = \frac{10}{100} \rightarrow 10^{\tt -2} = \frac{10}{100 \times 10} = \boxed{ \frac{10}{1000} }[/tex]

[tex]\large\underline{\textsf{Use the Negative Exponent Rule for our given expressions;}}[/tex]

[tex]\tt \frac{1}{10 \times 10 \times 10 \times 10 \times 10 \times 10} \overset{\textsf{is the same as}} \rightarrow \frac{1}{10^{6}}[/tex]

[tex]\textsf{There is a fraction for this expression, meaning that the exponent is negative.}[/tex]

[tex]\tt \frac{1}{10^{6}} = 10^{\tt -6}[/tex]

[tex]\large\boxed{\tt \frac{1}{10 \times 10 \times 10 \times 10 \times 10 \times 10} = 10^{\tt -6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt 10^{\tt -3} \times 10^{\tt 2}[/tex]

[tex]\textsf{Remember that when exponents multiply, they're going to add together due to}[/tex]

[tex]\textsf{this expression having at least 2 constants.}[/tex]

[tex]\tt 10^{\tt -3} \times 10^{\tt 2} \rightarrow 10^{\tt -3+2} \rightarrow 10^{\tt -1}[/tex]

[tex]\large\boxed{\tt 10^{\tt -3} \times 10^{\tt 2} \neq 10^{\tt -6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt 10^{\tt -3} + 10^{\tt -3}[/tex]

[tex]\textsf{We should know that adding exponents is not like adding whole numbers/terms.}[/tex]

[tex]\textsf{We will need to evaluate 10}^{\tt -3} \ \textsf{using the Negative Exponent Rule.}[/tex]

[tex]\tt 10^{\tt 0} = \frac{10}{10} \rightarrow \tt 10^{\tt -1} = \frac{10}{10 \times 10} = \frac{10}{100} \rightarrow \tt 10^{\tt -2} = \frac{10}{100 \times 10} = \frac{10}{1000} \rightarrow \tt 10^{\tt -3} = \frac{10}{1000 \times 10} = \boxed{\frac{10}{10000}}[/tex]

[tex]\tt \frac{10}{10000} \ \textsf{can reduce to} \ \boxed{\tt \frac{1}{1000}}[/tex]

[tex]\underline{\textsf{We are now adding;}}[/tex]

[tex]\tt \frac{1}{1000} + \frac{1}{1000} = \frac{2}{1000} \rightarrow \boxed{\frac{1}{500} }[/tex]

[tex]\textsf{This does \underline{not} evaluate to 10}^{\tt -6}[/tex]

[tex]\large\boxed{\tt 10^{\tt -3} + 10^{\tt -3} \neq 10^{\tt -6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt \frac{1}{10^{\tt 6}}[/tex]

[tex]\textsf{Because there's a fraction, the exponent is negative.}[/tex]

[tex]\large\boxed{\tt \frac{1}{10^{\tt 6}} = 10^{\tt -6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt \frac{10^{\tt 3}}{10^{\tt 9}}[/tex]

[tex]\textsf{Remember that when dividing exponents, they are going to subtract due to both}[/tex]

[tex]\textsf{of these numbers are constants.}[/tex]

[tex]\tt \frac{10^{\tt 3}}{10^{\tt 9}} \rightarrow \tt 10^{\tt 3-9} = 10^{\tt -6}[/tex]

[tex]\large\boxed{\frac{10^{\tt 3}}{10^{\tt 9}} = 10^{\tt -6}}[/tex]

[tex]\large\underline{\textsf{Hence;}}[/tex]

[tex]\large\boxed{\tt \frac{1}{10 \times 10 \times 10 \times 10 \times 10 \times 10} = 10^{\tt -6}}[/tex]

[tex]\large\boxed{\tt 10^{\tt -3} \times 10^{\tt 2} \neq 10^{\tt -6}}[/tex]

[tex]\large\boxed{\tt 10^{\tt -3} + 10^{\tt -3} \neq 10^{\tt -6}}[/tex]

[tex]\large\boxed{\tt \frac{1}{10^{\tt 6}} = 10^{\tt -6}}[/tex]

[tex]\large\boxed{\frac{10^{\tt 3}}{10^{\tt 9}} = 10^{\tt -6}}[/tex]

Answer:

A. n ≤ 10

Step-by-step explanation:

Corinna wants to buy a $229 plane ticket. She currently has $64, so she needs to save up $229 - $64 = $165. Since she earns $15 per hour, we can set up the equation n * 15 = 165, where n represents the number of hours Corinna needs to work. Solving for n, we get n = 11.1, which we can round down to 11 hours. Therefore, Corinna must work at least 11 hours to save up enough money to buy the $229 plane ticket. Answer choice A is the correct answer.

Note: Rounding down to 11 is not required, as long as we do not round up to 12. Rounded or unrounded, 11 is the smallest integer greater than or equal to 11.1, so it is the minimum number of hours Corinna would need to work to save up enough money for the plane ticket.
