Which angle is vertical to DEA?
Answer:
[tex]\large\boxed{\tt \angle BEC}[/tex]
Step-by-step explanation:
[tex]\textsf{We are asked for which angle is \underline{Vertical} to} \ \tt \angle DEA.[/tex]
[tex]\large\underline{\textsf{What are Vertical Angles?}}[/tex]
[tex]\textsf{Vertical Angles are 2 angles that are opposite from each other, and are formed}[/tex]
[tex]\textsf{by the same intersecting lines. Vertical Angles also have to share a common Vertex.}[/tex]
[tex]\textsf{*Vertical Angles are also congruent to each other.}[/tex]
[tex]\large\underline{\textsf{What is a Vertex?}}[/tex]
[tex]\textsf{A Vertex marks the point where 2 lines intersect. This is the point where angles}[/tex]
[tex]\textsf{are formed.}[/tex]
[tex]\large\underline{\textsf{Finding the Vertical Angle;}}[/tex]
[tex]\textsf{Our primary focus should be} \ \tt \angle DEA. \ \textsf{Remember that Vertical Angles are primarily angles}[/tex]
[tex]\textsf{opposite from each other. This only leaves one option which is} \ \tt \angle BEC. \ \textsf{Note how}[/tex]
[tex]\textsf{both angles are opposite from each other, and they share a common vertex point.}[/tex]
[tex]\textsf{Lastly, they are formed by the same intersecting lines, which guarantees they're}[/tex]
[tex]\textsf{vertical angles.}[/tex]

Negative Exponent Rule: Which expressions are equivalent to 10−6? Select all that apply.
Answer:
[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]

Find the surface area of the cube shown below.
a. 625 cm2
b. 1121 cm2
c. 726 cm2
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.

Sara had 136 dollars to spend on 8 books. After buying them she had 16 dollars. How much did each book cost ?
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.

The length of a rectangle is 5cm less than twice it's width. If the perimeter of the rectangle is no more than 80cm, what are the maximum possible dimensions?
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

The total number of questions in the biology test are 40.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
For one biology test, Jhon correctly answered 14 questions. This gave him a score of 35%.
Let the total number of questions be w.
Now, 35% of w=14
35/100 ×w=14
35w=1400
w=1400/35
w=40
Therefore, the total number of questions in the biology test are 40.

write each expression without using the absolute value symbol |14-(x-6)|
THIS IS 15 POINTS PLSSSSSSSSSSSSSS HELP
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)
