Pete's Pizza Parlor sells pizzas for $7 each. Pete's has a $5 fee for all delivery orders. What equation could be used to find C, the total cost, based on p numbers of pizzas?
Answer:
C = 5 + 7p
Step-by-step explanation:
Pete's Pizza Parlor sells pizzas for $7 each. Pete's has a $5 fee for all delivery orders.
Let p = Total number of pizzas
Hence:
The total cost C is written as:
C = $5 + $7 × p
C = 5 + 7p
Therefore, the equation that could be used to find C, the total cost, based on p numbers of pizzas is:
C = 5 + 7p

Order the numbers from least to greatest.
-0.25, 1/4,1/3,0.3
Answer: −0.25, 1/4, 1/3, 0.3
Step-by-step explanation:
Convert all numbers to decimals
−0.25 = −0.25
1/4 = 0.25
1/3 = = 0.3333...
0.3 = 0.3
Arrange the numbers in ascending order
−0.25, 0.25, 0.3333.., 0.3
Replace the numbers with the original numbers
−0.25, 1/4, 1/3, 0.3
A Family travels at a constant rate and drove 420 miles in 7 hours.If they drive at the same speed ,How many miles will they drive in the next four hours.?
Answer:
240 miles
Step-by-step explanation:
Step 1
We find the constant rate at which the family travels
Speed(Rate) = Distance/Time
A Family travels at a constant rate and drove 420 miles in 7 hours.
Speed(Rate) = 420 miles/7 hours
= 60 miles per hour
Step 2
If they drive at the same speed ,How many miles will they drive in the next four hours.?
We are to finally calculate the distance for the next 4 hours
Distance = Speed × Time
Speed = 60 miles per hour
Time = 4 hours
Distance = 60 miles per hour × 4 hours
Distance = 240 miles
Therefore, for the next 4 hours the number of miles they would drive is 240 miles

The length and width or a rectangular courtyard is 40 feet and 30 feet, respectively. In order to make the courtyard larger, an additional 15 feet is being added to the width
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet

3. The density of an object can be found with this formula...
D = M/V
D = Density, M = Mass, and V = Volume
Choose the correct equation for an object that has...
Density = ?, Volume = 10cm, Mass = 500g
Explanation:
Density = Mass/Volume
D = M/V
D = 500/10
D = 50 grams per cubic cm
Your teacher should have written cm^3, cc, or cubic cm instead of just "cm" to represent the volume. The abbreviation "cc" stands for "cubic cm" which you may hear a lot in hospital settings when it comes to medicine dosages.

Exactly 150 years ago, students planted a tree in front of their school. Since then, the tree has grown 33 meters taller and the distance around the trunk has increased by 3 meters. Use pencil and paper. Describe how you can use this information to find at least two different unit rates. Then find these unit rates.
Step-by-step explanation:
There are 2 different unit rates here:
The increase of the tree's height per year The increase of the tree's trunk per yearRate of tree's height per year
= 33m / 150 years = 0.22m per year.
Rate of tree's trunk per year
= 3m / 150 years = 0.02m per year.
wayne's country has a sales tax rate of 5%. How much does mike's car cost before tax if the total cost of the car plus tax is 13,032.60?
A percentage is a way to describe a part of a whole. The cost of the car is $12,412.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that Wayne's country has a sales tax rate of 5%. The total cost of the car plus tax is $13,032.60. Therefore, the total cost of the car can be written as,
The total cost of the car = Cost of the car + Tax on the car
$13,032.60 = Cost of the car + 5% of the cost of the car
Let the cost of the car be represented by x.
$13,032.60 = x + 5% of the x
$13,032.60 = x + 0.05
$13,032.60 = 1.05x
x = $13,032.60 / 1.05
x = $12,412
Hence, the cost of the car is $12,412.

Answer:
C. the slope of f(x) is less ...
Step-by-step explanation:
"Slope" is a signed number, so comparison using words like "less than" or "greater than" are expected to be used as they are in the context of signed numbers.
The slope of f(x) is the "rise" divided by the "run" of the graph. From left to right, the two points on the graph of f(x) have a "rise" of -2 for a "run" of +1. The slope of f(x) is ...
m = rise/run = -2/1 = -2
The slope of g(x) is the coefficient of the x-term, -7.
__
In the context of signed numbers, the slope of f(x) is -2 and the slope of g(x) is -7. We know -2 is greater than -7, so the slope of f(x) is greater than the slope of g(x).
However ...
In the real world, the slope of a hill is measured in the same way: rise is divided by run. The slope of a hill is always a positive number, because we're not concerned about what compass direction we're going. We're only concerned with how high we need to raise our foot to take the next step up the hill. That is, we're concerned with the "steepness" of the slope, its magnitude.
In that sense, the function g(x) changes 7 units for a change in x of 1 unit, and the function f(x) changes 2 units for the same change in x. Considered in this way, the "steepness" of the g(x) line is greater than that of the f(x) line. We can say the slope of f(x) is less than the slope of g(x).
_____
If the question is asking about the algebraic relation of the slopes of the lines, then the answer is ...
A. The slope of f(x) is greater ... (-2 > -7)
If the question is asking about the steepness of the lines, as we expect is the case, then the answer is ...
C. The slope of f(x) is less ... (2 < 7)

Answer:
x=2,y=5
Step-by-step explanation:
y=8x-11 ----(1)
y=-7x+19----(2)
Replace (1) in (2)
8x-11 =-7x+19
8x+7x=19+11
15x =30
x =30÷2
x =2
If x=2,then replace x=2 in (1)
y=8(2)-11
y=16-11
y=5
A triangle with sides of 14 15 and 29 does it form a right triangle 
Answer: No.
Step-by-step explanation: This triangle does not form a right triangle because it does not have a 90 degree angle.
Answer:
No
Step-by-step explanation:
Use Pythagorean Theorem: (a^2 + b^2 = c^2)
a^2 + b^2
(14)^2 + (15)^2
196 + 225 = 421
Now for c:
29^2 = 841
841 does not 421 so its not a right triangle
