Answer:
y=15x+5.50
Step-by-step explanation:
the y intercept or initial fee is 5.50 as written in the problem and the slope is 15 and a key word for that is each. meaning that y=15x+5.50
Find the area of the rhombus! Please help
Answer:
120
the equation to find the area of a triangle is[tex]A[/tex] = [tex]B[/tex] · [tex]H[/tex] [tex]/ 2[/tex]
Therefore,
[tex]A=(12[/tex] · [tex]5) / 2[/tex]
[tex]A=60/2[/tex]
[tex]A=30[/tex]
There are 4 congruent triangles in this rhombus and therefore,
[tex]30[/tex] · [tex]4=120[/tex]
[tex]A=120 cm^2[/tex]

What is the value of n in the equation
3n - 8 = 32 - n?
1.) -10
2.) -6
3.) 6
4.) 10
Answer:
n = 10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3n - 8 = 32 - n
Step 2: Solve for n
Add n on both sides: 4n - 8 = 32Add 8 on both sides: 4n = 40Divide 4 on both sides: n = 10Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 3(10) - 8 = 32 - 10Multiply: 30 - 8 = 32 - 10Subtract: 22 = 22Here we see that 22 does indeed equal 22.
∴ n = 10 is the solution to the equation.

Solve for y
5y- 10x = 45
Answer:
y=9 (x=-4.5)
Step-by-step explanation:
you have to split the equation up in order to solve
5y=45
divide by 5 on both sides
y=9
-10x=45
divide by -10
x=-4.5

What is an equation of the line that passes through the points (-6, -7) and
(6,3)? Put your answer in fully reduced form.
Answer: y = 5/6x - 2
Step-by-step explanation:
Y =mx + b
Step 1 find slope also known as m:
Y2 - y1 / x2 - x1
3-(-7)/6-(-6) = 10/12 can be reduced to 5/6
Step 2 find b:
3 = 5/6 (6) + b
3 = 30/6 + b
3 = 5 + b
-5 - 5
-2 = b
Step 3 write equation:
Y = 5/6x - 2

The Orlando Solar Bears had a successful season on the ice winning 80% of their games. They won a record of 32 games. How many games are in a season?
Answer:
lool
Step-by-step explanation:
if 4 is the constant of proportionality is this equation correct? y = 4x + 2
Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.
How much paint does Brielle need to finish her room
Answer:
Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.
Step-by-step explanation:
As, this question is incomplete, so we will create similar question and complete it. '
Let's suppose Brielle's room has following dimensions:
Length of two walls = 10 ft
Length of other two walls = 12 ft
Height of the room from bottom to ceiling = 10 ft
In order to calculate the amount of paint needed, we need to calculate the surface area of the room to be painted.
So, for that, add all the lengths together and multiply it by height of the room.
SF = (L1 +L2 +L3+ L4) x H
SF = (10 + 10 + 12 + 12) x (10)
SF = 440 sq.ft = Actual footage of the room to be painted.
Now, we have convert this number in gallons to know the amount of paint required to paint Brielle's room. For this, we need to divide our SF to 350 sq.ft per gallon.
Paint Needed = 440 sq.ft / 350 sq.ft per gallon
Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.

What is the slope of the line NP
Answer:
The slope of NP is [tex]\frac{-5}{7}[/tex] ⇒ B
Step-by-step explanation:
In any square, every two opposite sides are parallel and every two consecutive sides are perpendicularParallel lines have the same slopeThe product of the slopes of the perpendicular lines is -1, which means if the slope of one m, then the slope of the other is [tex]\frac{-1}{m}[/tex] (reciprocal m and change its sign)The rule of the slope of the line which passes through the points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]In square MNPR
∵ MN and NP are adjacent sides
∴ MN ⊥ NP
∵ M = (3, 8) and N = (-2, 1)
∴ x1 = 3 and y1 = 8
∴ x2 = -2 and y2 = 1
→ Use the rule of the slope above to find the slope of MN
∴ m(MN) = [tex]\frac{1-8}{-2-3}[/tex]
∴ m(MN) = [tex]\frac{-7}{-5}[/tex]
∴ m(MN) = [tex]\frac{7}{5}[/tex]
∵ MN ⊥ NP
∴ The product of their slopes = -1
→ Reciprocal the slope of MN and change its sign
∴ m(NP) = [tex]\frac{-5}{7}[/tex]
∴ The slope of NP is [tex]\frac{-5}{7}[/tex]
Lillian thinks that 725 - 4x3 is the same as 3.22. Which statement shows that it is
NOT the same?
Answer:
The correct option is (c).
Step-by-step explanation:
Lillian thinks that 7x⁵ - 4x³ is the same as 3x².
Option (a) :
7x⁵ - 4x³ = 3x²
It is wrong, as we cannot say directly that they are equal.
Option (b):
7x⁵ - 4x³ ≠ 3x²
It is wrong, as we cannot say directly that they are not equal.
Option (c):
7(2)⁵ - 4(2)³ = 3(2)²
LHS,
7(32) -4(8) = 192
RHS, 12
Here, LHS ≠ RHS
It is correct.
Option (d) :
7(2)⁵ × 4(2)³ = 3(2)²
Here, multiplication is done instead of addition. So, it is wrong.
Hence, the correct option is (c).

A milk truck delivers 386 dozen gallons of milk to stores in 1 day. Write and solve an equation to find n, the number of gallons of milk the milk truck delivers in 1 day.
Answer:
n = 4752 gallons
Step-by-step explanation:
Given
Dilivery: 396 dozen gallon in a day
RequirEd
determine the number of the gallon in a day
we understand that:
n= 396 dozen
unit conversion
1 dozen = 12
so
n = 396 dozen gallon
n = 396× 12
n = 4752 gallons
hence 4752 gallons milk is delivered daily

Multiply 3 3/8 • 4 1/3
Answer:
14 5/8
Step-by-step explanation
1) Convert the mixed number to an improper fraction
3 3/8 = 3 x 8 + 3 / 8 = 24 + 3/ 8= 27/8
2) Convert the second mixed number to an improper fraction
4 1/3 = 4 x 3 + 1/ 3 = 12 + 1/3= 13/3
3) Multiply 27/8 x 13/3= 351/24 divided by 3 = 117/8 117/8 as a mixed number is 14 5/8
4) 14 5/8 is the final answer simplified
Answer:
[tex]\frac{117}{8}[/tex] (or [tex]14\frac{5}{8}[/tex] in mixed number form)
Step-by-step explanation:
1) First, convert [tex]3\frac{3}{8}[/tex] and [tex]4\frac{1}{3}[/tex] into improper fractions. (Multiply the denominator by the whole number at the front, then add the numerator. The number that you receive from this would be the new numerator, and the denominator would still be the same.) This would be [tex]\frac{27}{8}[/tex] and [tex]\frac{13}{3}[/tex] respectively.
2) Multiply the two improper fractions. Multiply the numbers of the numerators and denominators together:
[tex]\frac{27}{8}[/tex]·[tex]\frac{13}{3}[/tex]
[tex]\frac{351}{24}[/tex]
3) Simplify the fraction. Find a number that both 351 and 24 can divide evenly into - in this case, it is 3. Divide both 351 and 24 by 3 and receive the final answer:
[tex]\frac{351}{24}[/tex]÷[tex]\frac{3}{3}[/tex]
[tex]\frac{117}{8}[/tex]
If you need it in mixed number form, find what times 8 can get closest to the number 117 without going over it. In this case, it is 14, since 14 times 8 is 112, and 112 is the biggest number closest to 117 that is still under it. 14 would be the whole number at the front Include the remainder, or how far away 112 is from 117, which is 5, at the numerator. The denominator would stay the same. Therefore, the answer in mixed number form is [tex]14\frac{5}{8}[/tex].
