Answer:
720 gallons
Step-by-step explanation:
First, find how many gallons are cleaned per hour.
You can use a ratio:
36 gallons = x gallons
1/4 hour 1 hour
Cross multiply:
36 (1) = 1/4x
36 = 1/4x
(36 = 1/4x) (4/1)
144 = x
x = 144
Then, use this info to find how many gallons per 5 hours.
You can use a ratio:
144 gallons = y gallons
1 hour 5 hour
Cross multiply:
144 (5) = 1y
720 = y
y = 720
There are 720 gallons cleaned per 5 hours.
i need help with this also. (homework due tomorrow)
Answer:
Using Pyhagoras theoram,
(H)^2 = (B)^2 + (P)^2
B = 13 in
P = 5 in
[tex](h)^{2} = (13)^{2} + {(5)}^{2} \\ = > (h)^{2} = 169 + 25 \\ = > (h)^{2} = 194 \\ = > h = \sqrt{194} \\ = > h = 13.92[/tex]
Hence, the missing side is 13.92 inhes.
Answer:
13.93
Step-by-step explanation:
[tex]5^{2} + 13^{2} = c^{2}[/tex]
[tex]25 + 169 = 194 = c^{2}[/tex]
[tex]\sqrt{194} = c^{2}[/tex]
[tex]13.92838827718 = c[/tex]
then round up to 13.93

y=1/2(x+4)(x-2) vertex
Answer:
(-1, -4.5)Step-by-step explanation:
[tex]y=\frac12(x+4)(x-2)\quad\implies\quad x_1=-4\,,\ \ x_2=2[/tex]
vertex is (p, q) where:
[tex]p=\dfrac{x_1+x_2}2=\dfrac{-4+2}2=\dfrac{-2}2=-1\\\\q=f(p)=\frac12(-1+4)(-1-2)=\frac12(3)(-3)=-\frac92=-4.5[/tex]
So the vertex is: (-1, -4.5)

Your task is to package 36 cans of tennis balls for shipping. Each tennis ball can contain 3 tennis balls.
You must box them in two rows of 18 cans.
When you go to the box store to purchase a box, you notice that the boxes come in a variety of sizes. All dimensions are in multiples of 6” (ie. 6”, 12”, 18”, etc.). Assume the diameter of one tennis ball is 3 inches. Use 3.14 as the value of .
When talking to the shipping clerk, you find out that there is an extra charge for any extra space in the shipping box that is not taken up by the cans because they have to fill that space in with a filler. Since you are on a tight budget, you want to spend the least amount of money as possible to ship this box.
Your task:
Choose the size box that fits the cans for your shipment.
L= W= H=
2) Determine how much extra space there is in your box after you have put the cans in
Answer:
1) L = 54", W = 6", H = 9"
2) Extra Space = 1389.96 in³
Step-by-step explanation:
1)
LENGTH:
Since, there will be 18 balls along the length of box. Therefore,
Length = L = (18 balls)(Diameter of 1 ball) = (18)(3'')
L = 54"
WIDTH:
Since, there will be 2 rows of cans, and hence, 2 balls along the width of box. Therefore,
Width = W = (2 balls)(Diameter of 1 ball) = (2)(3'')
W = 6"
HEIGHT:
Since, each can can hold 3 balls along the height of box. Therefore,
Height = H = (3 balls)(Diameter of 1 ball) = (3)(3'')
H = 9"
2)
First we calculate the total volume of box:
Total Volume = L*W*H = (54")(6")(9") = 2916 in³
Now, we calculate volume of one ball:
Volume of 1 Ball = (4/3)π(d/2)³ = (4/3)π(3"/2)³ = 14.13 in³
Now, we calculate the total number of balls in box:
No. of Balls = (Balls along length)(Balls along width)(Balls along height)
No. of Balls = (18)(2)(3) = 108 balls
Now, we calculate the total volume of box occupied by balls:
Total Volume occupied by Balls = (No. of balls)(Volume of 1 Ball)
Total Volume occupied by Balls = (108)(14.13 in³)
Total Volume occupied by Balls = 1526.04 in³
Hence, the extra space will be:
Extra Space = Total Volume of Box - Total Volume Occupied by Balls
Extra Space = 2916 in³ - 1526.04 in³
Extra Space = 1389.96 in³
Which value of x makes the equation -5x-(-7-4x) =-2(3x-4 true?
Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for x
Distribute: -5x + 7 + 4x = -6x + 8Combine like terms: -x + 7 = -6x + 8Add 6x to both sides: 5x + 7 = 8Subtract 7 on both sides: 5x = 1Divide by 5 on both sides: x = 1/5Step 3: Check
Plug in x to verify it's a solution.
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5

What is the measure of angle 1 in degrees?
Answer:
73 degrees
Step-by-step explanation:
The interior angle equals to 180. 73+37+ m<2 = 180. That means angle 2 is 70 degrees.
m<1 and m<C and equal due to alternate interior angles. That means angle 1 is 37 degrees.
We know angles 1 and 2 equal to 37 and 73. That means the angles are equal to the interior triangle. 70+37= 107. 180-107= 73 Degrees

What is the range of this quadratic function?
Answer:
(negative infinity, 4]
Step-by-step explanation:
Reminder: the range is all the possible y values the function can get by plugging in x values.
Since this is a downward opening parabola, it won't have a lower boundary, which means that the answer must be (negative infinity, 4]
We can further check that's correct by seeing that the parabola has its vertex at 4, which is written in the answer.
That means the correct answer must be (negative infinity, 4]

Find the measure of each angle. Assume the lines are parallel.
Answer:
2 = 67
3 = 113
4 = 67
5 = 113
6 = 67
7 = 113
8 = 67
Step-by-step explanation:
opposite angle have to equal 180 because if you combine them they just become the line.
since the lines are parallel, measurements will be the same for the bottom set of angles as they are the top set of angles.

Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 minutes Ye is 2 miles from home. Which equation models his distance from home y, in terms of minutes, x?
Answer:
[tex]y = -\frac{1}{5}x + 5[/tex]
Step-by-step explanation:
Given
[tex]5\ minutes = 4\ miles[/tex]
[tex]15\ minutes = 2\ miles[/tex]
Required
Determine the equation
y represents distance
x represents time
So, the given parameters can be modeled (x,y) as:
[tex](x_1,y_1) = (5,4)[/tex]
[tex](x_2,y_2) = (15,2)[/tex]
First, we need to determine the slope of the function.
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 - 4}{15 - 5}[/tex]
[tex]m = \frac{-2}{10}[/tex]
[tex]m = -\frac{1}{5}[/tex]
The equation can be determined using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = -\frac{1}{5}[/tex]
[tex](x_1,y_1) = (5,4)[/tex]
[tex]y - y_1 = m(x - x_1)[/tex]
becomes
[tex]y - 4 = \frac{-1}{5}(x - 5)[/tex]
Open bracket
[tex]y - 4 = -\frac{1}{5}x + 1[/tex]
Solve for y
[tex]y = -\frac{1}{5}x + 1 + 4[/tex]
[tex]y = -\frac{1}{5}x + 5[/tex]
A frozen yogurt shop offers a rewards system for frequent customers. The graph below represents how much a rewards customer pays based on the number of ounces of frozen yogurt purchased.
A graph titled Customer Rewards. The horizontal axis shows ounces of yogurt purchased, numbered 2 to 22, and the vertical axis shows Total Spent (dollars) numbered 1 to 11. A line begins at 0, extends to 5 dollars spent at 10 to 12 ounces, and ends at 9 dollars spent at 20 ounces.
Which statement describes the total amount a rewards customer pays for 10 ounces and 12 ounces of yogurt?
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
A rewards customer pays $5 per ounce because the total amount paid is always increasing.
A rewards customer pays $20 for 10 or 12 ounces of yogurt because the total amount paid is increasing.
A rewards customer earns 5 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
Answer:
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

11) The sum of three consecutive integers is 13 greater than twice the smallest of the three integers. Find the integers.
Answer:
The sum of 3 consecutive integers is 13 more than twice the smallest integer. Find the integer.
x + (x+1) + (x+2) = 2x + 13
3x + 3 = 2x + 13:
3x - 2x = 13 - 3
x = 10 is the smallest integer:
Check: 10 + 11 + 12 = 2(10) + 13
The integers will be equal to 10, 11, and 12 respectively.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The sum of 3 consecutive integers is 13 more than twice the smallest integer. The integer will be calculated as below:-
x + (x+1) + (x+2) = 2x + 13
3x + 3 = 2x + 13:
3x - 2x = 13 - 3
x = 10 is the smallest integer:
Check: 10 + 11 + 12 = 2(10) + 13 = 33
Therefore, the integers will be equal to 10, 11, and 12 respectively.
