Answer:
62° and 54°
Step-by-step explanation:
The exterior angle of a triangle is equal to the 2 opposite interior angles.
116° is an exterior angle of the triangle, thus
2x + 4 + 3x - 13 = 116, that is
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Thus
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°
∠ B = 2x + 4 = 2(25) + 4 = 50 + 4 = 54°

Answer:
91
Step-by-step explanation:
There is a rule that says that 129 = 38 + x
so x = 129 - 38
x = 91
Answer:
x = 91.
Step-by-step explanation:
129 = x + 38
First, we can subtract 38 from both sides to get:
91 = x
So the solution is x = 91.

6 times _ equals 9
12 times _ equals 3
Answer:
6 times 1.5 equals 9. Essentially, this is just 1 and a half of 6, meaning you have 6, and half of 6, 3, together.
12 times 0.25 equals 3. Multiplying something by 0.25 has the same effect as dividing by 4, as both results in a quarter of the original number. Since 3 is a quarter, or 1/4 the size of 12, that means that multiplying it by 1/4 or 0.25 will give us 3.

Match the following items by evaluating the expression for x = -2.
x ⁻²
x ⁻¹
x ₀
x ¹
x ²
Options: 4, 1/4, -1/2, -2, and 1 (you can use them more than once)
Step-by-step explanation:
Using x = -2, we can evaluate each expression as follows:
x ⁻² = (-2)⁻² = 1/(-2)² = 1/4
x ⁻¹ = (-2)⁻¹ = -1/2
x ₀ = -2
x ¹ = -2
x ² = (-2)² = 4
Matching these values with the given options, we get:
x ⁻² = 1/4
x ⁻¹ = -1/2
x ₀ = -2
x ¹ = -2
x ² = 4
So the match is:
x⁻² = 1/4
x⁻¹ = -1/2
x₀ = -2
x¹ = -2
x² = 4
Answer:
1/4-1/21-24Step-by-step explanation:

Answer the questions below.
(a)
The perimeter of the rectangular garden is 330 m.
If the width of the garden is 77 m, what is its length?
Length of the garden: [] m.
(b)
The area of a rectangular window is 6734 cm².
If the length of the window id 91 cm, what is its width?
Width of the window [] cm.
Answer:
(a) 88 m
(b) 74 cm
Step-by-step explanation:
You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.
(a) PerimeterThe perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Filling in the given values, we can find the unknown.
330 = 2(L +77)
165 = L +77 . . . . . . . divide by 2
165 -77 = 88 = L
The length of the garden is 88 meters.
(b) AreaThe area of a rectangle is given by the formula ...
A = LW
Filling in the given values, we can find the unknown.
6734 = 91W
6734/91 = 74 = W
The width of the window is 74 cm.

Answer:
Step-by-step explanation:
The number 1032 is called the numerator or dividend, and the number 43 is called the denominator or divisor.
The quotient of 1032 and 43, the ratio of 1032 and 43, as well as the fraction of 1032 and 43 all mean (almost) the same:
1032 divided by 43, often written as 1032/43.
1032 divided by 43 in decimal = 24
1032 divided by 43 in fraction = 1032/43
1032 divided by 43 in percentage = 2400%
Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 1032 and 43, of course.
Repetends, if any, are denoted in ().
The conversion is done automatically once the nominator, e.g. 1032, and the denominator, e.g. 43, have been inserted.
The quotient and remainder of 1032 divided by 43 = 24 R 0
The quotient (integer division) of 1032/43 equals 24; the remainder (“left over”) is 0.
1032 is the dividend, and 43 is the divisor.

why isn't m^3=512 ±8, but just 8? I went onto 2 diff websites and the answer book (yes i have an answer book) and it says 8.
Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.
A rectangle has a length of 26 inches and a width of 14 inches. If 1 inch = 2.54 centimeters, find the area of the rectangle in centimeters. Round the answer to the nearest tenth.
560.4 cm2
56.4 cm2
2,348.4 cm2
924.6 cm2
The solution is Option C) 2348.4 cm²
The area of Rectangle in centimeters is 2348.4 cm²
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
The length of the rectangle = 26 inches
= 26 x 2.54
= 66.04 centimeters
The width of the rectangle = 14 inches
= 14 x 2.54
= 35.56 centimeters
The area of the rectangle = length of the rectangle x width of the rectangle
So ,
The area of the rectangle = 66.04 centimeters x 35.56 centimeters
= 2348.3824 cm²
≈ 2348.40 cm²
Therefore , the area of the rectangle is 2348.4 cm²
Hence , the area of the rectangle in centimeters is 2348.4 cm²

To make things easier, this solid can be divided in 3 parts:
- the first one is 2in long, 5in wide and 8in tall
- the second one is 2in long, 8in wide and 3in tall
- the third one is just like the first one, so 2in long, 5in wide and 8in tall
In order to find the volume of the solids, we need to multiply their dimensions:
1st: 2.5.8 = 80\(in^{3}\)
2nd: 2.8.3 = 48\(in^{3}\\\)
3rd: 2.5.8 = 80\(in^{3}\)
The volume of the big solid is equal to (80 + 48 + 80)\(in^{3}\)
V = 208\(in^{3}\)

Marsha and Tian are making table decorations for a party. Marsha made 2/9 of a decoration in half and hour. Tian made 2/3 of a decoration in the same amount of time. How much more of a decoration did Tian make in a half and hour?_______
How much would they make in a half hour if they worked together?______
Answer:
4/9 and 8/9
Step-by-step explanation:
\(\frac{2}{3}\) and \(\frac{2}{9}\) you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer.
