Answer:
The cost of each:
1 cheese slice = c = $3.75
1 pepperoni slice = p = $2.5
Step-by-step explanation:
Let the cost:
1 cheese slice = c
1 pepperoni slice = p
Two friends are going to the mall to buy pizza.
One of the friends buys 1cheese slice and 2 pepperoni slices for $8.75.
c + 2p = $8.75.....Equation 1
c = $8.75 - 2p
Her friend purchases 2 chese slices and 3 pepperoni slices for $15.00.
2c + 3p = $15.00.....Equation 2
We substitute 8.75 - 2p for c in Equation 2
2(8.75 - 2p) + 3p = $15.00
17.5 - 4p + 3p = 15
Collect like terms
- 4p + 3p = 15 - 17.5
-p = -2.5
p = $2.5
c = $8.75 - 2p
c = $8.75 - 2(2.5)
c = $8.75 - 5.0
c = $3.75
The cost of each:
1 cheese slice = c = $3.75
1 pepperoni slice = p = $2.5
What is the slope of the line?
Answer:
-1
Step-by-step explanation:
Remember, slope is rise/run
Start from a point on the line and count up and over until you reach another point on the line.
For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.
Since the line represents a negative slope, the slope is -1.

A cylindrical water vessel of diameter 1.4 m holds 770 litres of water. find the height of the vassel
Answer:
Answer at the bottom!!
Step-by-step explanation:
Given the diameter of cylinder = 1.4 m
=> Radius = 1.4/2 = 0.7 m
We know that volume of a cylinder = πr²h
= 3.14 x 0.7² x 2.1= 3.23 m³
For the pipe radius = 3.5/2 = 1.75 cm = 0.0175m
water flows at a rate of 2 m per second
So, volume of water discharged in one second by pipe = πr²L
= 3.14 x 0.0175² x 2=0.0019
Hence time taken by the pipe to fill the cylinder
= 3.23/0.0019= 1700 sec
= 28 minutes and 20 seconds
Hence the time taken by the pipe to fill the cylinder is 28 minutes and 20 seconds.
Hope this helps!!

Step-by-step explanation:
Eddie has saved up $45 to purchase a new camera from the local store. The sales tax in his county is 7% of the sticker price. Write an equation and solve it to determine the value of the highest priced camera Eddie can purchase with his $45, including the sales tax. Round your answer to the nearest penny
Answer:
hi
Step-by-step explanation:
=================================================
Explanation:
x = price of camera before tax
1.07x = price of camera after tax
note how 1.07 is the result of 1 + 0.07
1 = 100%
0.07 = 7%
1.07 = 107%
So 1.07 means the price has gone up by 7%
Set 1.07x equal to 45 and solve for x
1.07x = 45
x = 45/1.07
x = 42.0560747663551
x = 42.06
The highest price Eddie can afford is $42.06, which is the value of the camera before tax is applied
--------------------
note how 7% of 42.06 = 0.07*42.06 = 2.9442 = 2.94
So the tax is $2.94 which adds onto the $42.06 to get
2.94+42.06 = 45

Answer:
5.61 billion dollars.
Step-by-step explanation:
4.61+1.03=5.61
Answer:
0.223
Step-by-step explanation:
Change the divisor 4.61 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
103 ÷ 461 = 0.223
and therefore:
1.03 ÷ 4.61 = 0.223
Both calculated to 3 decimal places.
I need help with this question in Geometry.
Answer:
846 in
Step-by-step explanation:
48*15+21*6
720+126=846
Answer:
846 square inches.
Step-by-step explanation:
All you have to do is find the area of the net for the seat back.
Bottom and Top
L = 21 + 3 + 21 + 3 = 48
W = 15
Area
Area = L * w
Area = 48 * 15
Area = 720
Area of the 2 sides .
L = 21
w = 3
Area =2 * L * w There are 2 of them
Area = 21*3 * 2 126
Total 846

The largest ball of yarn ever created has a radius of 6 feet. It took 30 years to create.
Using 3.14 for pi which choice is the volume of the ball of yarn nearest hundred
87.85 cubic feet
150.72 cubic feet
834.68 square feet
904.32 cubic feet
Answer:
904.32 cubic ft
Step-by-step explanation:
To find the volume of a sphere, the formula is [tex]4\pi\frac{r^3}{3}[/tex]
First, 3.14 * 4 for 12.56.
The radius is 6, and that cubed is 216.
After that, divide 216 by 3 for 72
Then, 12.56 times 72, which gets you the final answer of 904.32 cubic ft.
(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)
720 + 144 = 864
864 + 36 = 900
900 + 4.32 = 904.32

laura graphed the function below y = 1 / 2(One over two)x + 4
if the range of the function is restricted to 2 ≤ y ≤ 6, what is the domain?
Step-by-step explanation:
y = 0.5x + 4
When y = 2, x = -4. (shown in graph)
When y = 6, x = 4. (shown in graph)
Hence the domain would be -4 <= x <= 4.

When Keisha installed a fence along the 200-foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate.
.
What is the value of x, if the equation 2(x + 60) + 2(30) = 200 represents the Perimeter for the fencing of the backyard?
Answer:
Step-by-step explanation:
From the picture attached, equation of the perimeter of the fence of the backyard should be,
(x + 60) + (60) + 2(30) = 200
x + 2(60) + 2(30) = 200
x + 120 + 60 = 200
x + 180 = 200
x = 200 - 180
x = 20 ft
If the given equation for the perimeter for the fencing of the backyard (As given in the question) is,
2(x + 60) + 2(30) = 200
2x + 120 + 60 = 200
2x + 180 = 200
2x = 20
x = 10 ft
Answer:
2(x + 60) + 2(30) = 200
2x + 120 + 60 = 200
2x + 180 = 200
2x = 20
x = 10 ft

Triangles 1 and 2 are both isosceles. They each have a 30 degree angle. Explain why these triangles don't have to be similar to each other.
Step-by-step explanation:
Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.
Since they do not have all 3 congruent angles, they are not similar.

i. After how many weeks will Jennifer and William have the same amount of money in their bank accounts?
ii. How much will be in their accounts?
Answer:
5 weeks$100Step-by-step explanation:
Part iJennifer's account:
f(x) = 10x + 50William's account can be expressed as:
g(x) = 14x + 30Because the rate of change is 14 and y-intercept is 30
They will be same after x years, f(x) = g(x)
10x + 50 = 14x + 3014x - 10x = 50 - 304x = 20x = 5The accounts will be same after 5 weeks
Part iiThe amount in the accounts after 5 weeks:
f(5) = g(5) = 10*5 + 50 = $100Answer:
5 weeks
Step-by-step explanation:
Find the equation of willam's account:
1. find rate x1-x2
44-30 plug in
14 =rate 30=y-intercept starting valuse is always intercept
44+14=58 check
f(x)= 10x+50
f(x)= 14x+30 solve
10x+50=14x+30 set values together
20=4x subtract 10x and 30 from both sides
x=5
