A 3-gallon container of window cleaner costs $23.88. What is the price per quart?
Answer:
i think its 1.99
Step-by-step explanation:
Answer: $1.99
Step-by-step explanation:

What is the total area, in square units, of the four triangular faces of a right, square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units
Given :
Square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units.
To Find :
The total area, in square units, of the four triangular faces of a right.
Solution :
We know, area of square based prism is given by :
[tex]A = a^2 + \dfrac{ah}{2}[/tex]
Here, a is the length of square base and h is the height .
[tex]A = 6^2 + \dfrac{6\times 5}{2}\\\\A = 51 \ units^2[/tex]
Therefore, total area in square units is 51.

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

Step-by-step explanation:
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
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second. y=-16x^2+218x+75
Answer:
6.81s
Step-by-step explanation:
First you must know that the velocity of the body is zero at the maximum height.
v =dy/dx
v= -32x+218
Since v = 0
-32x+218 =0
32x =218
x= 218/32
x = 6.81s
Hence the rocket reaches its maximum height after 6.81s

Step-by-step explanation:
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!!

Answer:
240
Step-by-step explanation:
240 + 60 = 300 you can tell this by realising that ratio to have 4x one over the other would be 20 per 100, using this rate 3x, 240 and 60
Answer:
x = 60
Step-by-step explanation:
Length of small piece = x
length of large piece = 4x
x+ 4x = 300
5x = 300
x = 60

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

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.
Divide.

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.

sin^2a-sin^2b=cos^2b-cos^2a
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then sin²x = 1 - cos²x
Consider the left side
sin²a - sin²b
= (1 - cos²a) - (1 - cos²b)
= 1 - cos²a - 1 + cos²b
= cos²b - cos²a
= right side , thus verified

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.
