The amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. The dishwasher uses 32 gallons of water to wash 4 loads of dishes.
How many gallons of water will the dishwasher use to wash 12 loads of dishes?
Answer:
I believe it 96.
Step-by-step explanation:
32÷4=8
4×8=32
12×8=96
Answer:
96 gallons
Step-by-step explanation:
So to wash 4 loads of dishes, you need 32 gallons. If you divide 32 by 4 you get 8. That means you need 8 gallons of water per load. Since there are 12 loads and you need 8 gallons per load, if you multiply 8 X 12 you get 96. This means you need 96 gallons of water for 12 loads of dishes. Hope it helps!

Magdeline wants to know if the number of words on a page in her computer science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9
She claims that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page. Based on the data, is this a valid inference? (10 points)
Group of answer choices
Yes, because there is a lot of variability in the computer science book data
Yes, because the mean is larger in the computer science book
No, because the mean is larger in the computer science book
No, because there is a lot of variability in the computer science book data (brainliest if its right)
Answer:
The answer is D: To know on which book, number of words is more between, Computer Science and Math
Magdeline selects 25 pages from each book, then Calculates Mean, Median, Mean Absolute Deviation of number of words on each page.
Book Mean Median Mean Absolute Deviation
Computer science 48.7 40 9.4
Math 34.2 45 1.9
Observing what Magdeline has Done,
Mean is Sum of words on each page of 25 pages divided by 25.
1. Mean of Computer Science book is more than mean number of words on pages of math book.
2.And, Median means , computer science book has more pages which contains 40 words ,and Math book has more pages which contain 45 words.
3.Now,Coming to Mean Absolute Deviation, which measures the Variability from Mean.
In computer science book ,there is more Variability that is, 9.4 and 1.9 in math book.
So, just by claiming, that because the mean number of words on each page in the computer science book is greater than the mean number of words on each page in the math book, the computer science book has more words per page appears invalid Inference, because variability from mean in computer science book is more than variability from mean in Math book because Mean Absolute Deviation measures Variability fro mean.

$15 for 5 pairs of socks; $25 for 10 pairs of socks Determine if each pair of ratios or rates are equivalent. Explain your reasoning.
Answer:
These ratios are not equivalent.
Step-by-step explanation:
If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.
So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.
You are spending more money on the 5 pairs of socks for $15.
The function is given by the formula f(x)=3x+2.
a) Find f(7)
b) Find the value of x such that f(x)=15
Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3

Make h the subject of the formula:
d=√(3h/2)
Answer:
Do you mean d = √(3h/2)?
Square both sides:
d² = √(3h/2)²
d² = 3h/2
Then, multiply both sides by 2/3 to obtain:
h = 2d²/3

The graph shows the number of quarts picked and the amount of money the customer paid.
Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?
Answer:
$3.50 for 1 quart
Step-by-step explanation:
Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).
What is the importance of graphs in our daily life?Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.
Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.
Slope of the given graph = y₂ - y₁ / x₂ - x₁
Slope of the given graph = 3.5-0 /1-0 = 3.5
As the Graph is passing through the origin point
Hence, the equation of the line will be y = mx
Where slope(m) = 3.5
thus the equation of the given graph y = 3.5 x
For another customer given, y = 8.75
Hence x = 8.75/3.5
x = 2.5
Coordinates over the graph will be(2.5, 8.75)
Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).

Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan’s height in centimeters?
Answer:
Thus the answer is 127
Step-by-step explanation:
4 feet = 48 inches. 2.54 = 1 inch.
It is found that Joan's height is 127 centimetres.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .
First we change her height to inches;
1 Foot = 12 Inches
Therefore, 4 Feet = 4 x 12 = 48 inches
The Total height in inches =48 inches + 2 Inches = 50 inches
Now, we have gotten her height in inches, change to centimetres.
We have that;
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Hence, Joan's height is 127 centimetres.
