Answer:
A. 3yd
Step-by-step explanation:
There are two formulas that can be used for the circumference of a circle:
c = πd and c = 2πr
Since we want to solve for the radius, let's use c = 2πr
The circumference, 'c', is 18.84 inches
Since 'π' is an irrational number, we use its approximation of 3.14
We are trying to solve for 'r', which is the radius
The circumference, 'c', is 18.84 inches
Since 'π' is an irrational number, we use its approximation of 3.14
We are trying to solve for 'r', which is the radius
Plugging in, we get:
18.84 = 2(3.14)r
Since 'π' is an irrational number, we use its approximation of 3.14
Notice there are the same amount of decimal places (two!) in the answer as the combined amount of spaces in the numbers being multiplied!
18.84 = 6.28r
The goal is to isolate and solve for 'r', which is the radius
18.84/6.28 = 3
So we get "3 = r", which means the radius is 3 inches!
Kenna's bedroom is 12 feet long by 8 feet long. Her parents have agreed to buy new carpet for the entire bedroom.The carpet costs $15 per square meter. What will be the total cost of the new carpet? 1 foot = 0.305 meter
A. $439.20
B. $54.90
C. $133.96
D. $91.50
Answer:
C. $133.96
Step-by-step explanation:
Convert units:
12 · 0.305 = 3.66 m
8 · 0.305 = 2.44 m
Find the area of the room:
3.66 m · 2.44 m = 8.9304 m²
Find the cost:
8.9304 · 15 = 133.96

Answer:
3x + 132⁰ = 180⁰
3x = 48
x = 16⁰
Answer:
3x + 132 = 180°
Step-by-step explanation:
There are 3 x's and all of them need to be added in order to find the angle. Looking at the overall sum of the angle, a strait line would = 180°. Also, remember to use PEMDAS rules, before writing down your equation.

Jonas has 1728 copies of a 1 × 1 × 1 cube with the net
shown, where c is a positive integer and c < 100. Using
these 1728 cubes, Jonas builds a large 12×12×12 cube in
such a way that the sum of the numbers on the exterior
faces is as large as possible. For some values of c, the sum
of the numbers on the exterior faces is between 80 000 and
85 000. The number of such values of c is
(A) 39 (B) 38 (C) 37
(D) 36 (E) 35
Answer:
37 :))
Step-by-step explanation:
Look thorugh the photo B)
Sorry its diagonal
The number of such values of c is 37, whose sum
of the numbers on the exterior faces is between 80 000 and
85 000.
The correct option is (C)
What is inequality?
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Corners: (2c+100) x 8Non- corners: 10(c+100) x 4 x210 x 10x 100 x 2 =200002. Middle Layers:
Corners: (c+100)x 4 x 10Non- Corners: 100 x 10 x 4 x 10 =40000So,
(2c+100) x 8 + 10(c+100) x 4 x2 + (c+100)x 4 x 10 + 20000 + 40000
16c + 800 + 80c + 8000 + 40c + 400 + 60000
136c + 72800
As per the condition:
136c + 72800≤ 85000136c≤85000-72800c≤89
and, 136c≥80000-72800
c≥53
c= 89-53 =37
Hence, the number of such values of c is 37

Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5
Answer:
C. y = 1/2x + 5
Step-by-step explanation:
For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.
For D. it doesn't even have x in it, so basically y equals a number.
C. is a linear equation, y = 1/2x + 5
A football player attempts to kick a football across a field. The path of the football can be modeled by the function h(x) = − 1/225 x^2 + 2/3 x, where x is the horizontal distance from the kick, and h(x) is the height of the football above the ground, when both are measured in feet. How far from the kicker will the football land?
connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?
Answer:
96
Step-by-step explanation:
Step 1: Multiply 60% by 40
40 x .60 = 24
24 is 60 percent of 40
Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.
100 ÷ 25 = 4
Step 3: Multiply 4 by 24
4 x 24 = 96
The answer is 96 :)

Answer:
[tex]6\frac{1}{2}[/tex]
Step-by-step explanation:
When given the following problem:
[tex]7\frac{1}{7}-\frac{9}{14}[/tex]
Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.
[tex]\frac{50}{7}-\frac{9}{14}[/tex]
To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),
[tex]\frac{100}{14}-\frac{9}{14}[/tex]
Perform the operation, subtract one numerator from the other, leave the denominators the same,
[tex]\frac{91}{14}[/tex]
Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.
[tex]6\frac{7}{14}[/tex]
Reduce, divide the numerator and denominator by a common fraction,
[tex]6\frac{1}{2}[/tex]

Which of the following are needed to make an expression?
A. variable(s)
B. number(s)
C. equal sign
D. operation(s)
Answer:
variables is the correct answer
Answer:
ALL OF THE ABOVE
Step-by-step explanation:
An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.
It can be all of the above too. because everything is needed to make an expression.
