Answer:
NRS
Step-by-step explanation:
0.5(8-2x)=3-(x-1) Set up problem
4-1x =3-x-1 Distribute
4-1x =2-x Combine like terms
+x +x Add x to both sides to isolate x
4 =2 4 does not equal 2, so there are NRS.
2x(x + y) + 2(x2 + 3xy)
Answer:
4x² + 8xy
Step-by-step explanation:
Given
2x(x + y) + 2(x² + 3xy) ← distribute both parenthesis
= 2x² + 2xy + 2x² + 6xy ← collect like terms
= 4x² + 8xy
2. Solve the following quadratic equation by factorization method. m² - 14m + 13 = 0
Answer:
M = 1 & 13M²-14m+13 = 0
m²-13m-m+13 = 0
m(m-13)-1(m-13) = 0
(m-1)(m-13) = 0
m = 1 & 13
Step-by-step explanation:
M²-14m+13=0
=> m²-13m-m+13=0
=> m(m-13)-1(m-13) = 0
=> (m-1)(m-13)=0
=> m= 1 and 13

Jack wants to know how much water a sphere can hold with a radius of 8 cm. Find the volume. Use 3.14 for pi
Answer:
268 cm³
Step-by-step explanation:
Hey There!
So the first thing we want to do is find the formula for the volume of a sphere
[tex]V = \frac{4}{3} r^2[/tex]π
so we just plug in 8 for r or radius
8²=64
[tex]64x\frac{4}{3} = 85 \frac{1}{3}[/tex]
[tex]85\frac{1}{3} * 3.14 = 267.9466667[/tex]
Then we just round
Therefore the volume of the sphere is 268 cm³

Hey There!
This is true because if you plug in 5 to n
5+6
then you get that it equals 11
So 5=n is true

(Are the two triangles similar? Explain, step by step, how you know. )
Answer:
The two triangles can be considered similar as Angle A is 70 degrees and Angle B is a congruent angle to Angle A, which can be proven by adding 70 to 110 which shows a 180 degree angle (flat angle). Therefore we know that this triangle is similar
Step-by-step explanation:
y = 2x + 1
y = x + 3
y = x + 3
y = -3x − 2
y = -x − 7
y = x + 3
y = -x − 7
y = 2x + 1
y = 2x + 1
y = -3x − 2

Amir has 48 ounces of cashews, walnuts, and pecans. He adds x ounces of peanuts to create a mixture. Write a function
M(x) that represents the number of ounces of all nuts in the mixture. Write a function N(x) that represents the number
of ounces of peanuts in the mixture. Then find (?) (x) and explain what this function represents.
Answer:
I don't know sorry
Step-by-step explanation:
ask tutor
The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, Amir has 48 ounces of cashews, walnuts, and pecans.
He adds x ounces of peanuts to create a mixture.
M(x) that represents the number of ounces of all nuts in the mixture.
M(x)=48
N(x) that represents the number of ounces of peanuts in the mixture.
So, N(x)=x
Now, (M/N)(x) = M(x)/N(x)
= 48/x
Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

Semi-Trailers are rectangular prisms.
The standard height inside the trailer is
108 inches. If it's 8 ft wide and 20 ft long,
How much toilet paper can it deliver to the
Publix near Ms. Arruda's house?
Hint: Make sure you are using the same units. 1ft = 12in
Answer:
1440ft^3
Step-by-step explanation:
Volume of a rectangular prism = Length* width * Height
Given
width = 8ft
Length = 20ft
height = 108in
Convert 108 inches to feet
1ft = 12in
x = 108in
x = 108/12
x = 9ft
Get the volume of the prism
Volume = 8 * 20 * 9
Volume = 1440ft^3
Hence the volume of toilet paper it can deliver is 1440ft^3

A farmer wants to build two fenced-off sections within his field, one in the shape of a rectangle and the other in the shape of a square. The side of the square must be equal to the width of the rectangle, x feet. The length of the rectangle must be 50 feet longer than its width. The field the farmer wants to build the two fenced sections in has an area of y square feet. The difference of the area of this field and the area of the fenced, square section needs to be at least 1,000 square feet. In addition, the sum of the fenced areas must be less than the area of the field. This is the system of inequalities that represents this situation. Which points represent viable solutions?

3.14 to approximate pi. (Show your work.)
Answer:
Answer: 284.7
Step-by-step explanation:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
