my mom homeschools me and she has this thing called desmos so I'm trying to figure this out
Answer:
250 gallons of water are being pumped out each hour
Step-by-step explanation:
It tells us that W is the amount of water in the pool at a time. It also tells us that at the start there is 9000 gallons in the pool. We also know t is the time in hours so 1 t = 1 hour.
W=9000-250t
We can substitute in what we know
The amount of water in the pool = 9000 gallons - 250 gallons times 1 hour
so that means if one hour passes 250 gallons are removed, and if 2 pass then 500 are removed showing that for every hour the pump is on 250 gallons of water are being sucked from the pool

The given recipe makes 8 bags.
To make 16 bags, Lily needs twice as many ingredients because 8 + 8 = 16.
Since 1 cup of raisins makes 8 bags, 2 cups of raisins will make 16 bags.
To show the mathematical way:
Variable w = number of cups of raisins
1/8 = w/16
Cross multiply
1 × 16 = 8 × w
16 = 8w
2 = w
2 cups of pretzels makes 8 bags so 6 cups of preztels will make how many bags?
Set up an equation:
Variable x = number of bags
2/8 = 6/x
Cross multiply
2 × x = 8 × 6
2x = 48
x = 24
6 cups of pretzels will make 24 bags.
If 0.5 cup of pecans = 2.5 cups of crackers, then 1 cup of pecans = y cups of crackers?
Variable y = number of cups of crackers
Set up equation:
0.5/2.5 = 1/y
Cross multiply
0.5 × y = 2.5 × 1
0.5y = 2.5
y = 5
1 cup of pecans will need 5 cups of crackers
2 cups of pretzels = 8 bags, so 1 cup of preztels = z bags?
Variable z = number of bags
Set up equation:
2/8 = 1/z
Cross multiply
2 × z = 8 × 1
2z = 8
z = 4
Simplify the expression below.

Pl help it’s for a grade
Step-by-step explanation:
Given,
1. The given expression is [tex]\sqrt[10]{x^9}[/tex].
We need to write it into exponential form.
We know that,
[tex]\sqrt[a]{x} =x^{1/a}[/tex]
Here, a = 10
So,
[tex]\sqrt[10]{x^9}=(x^9)^{1/10}\\\\=x^{9\times \dfrac{1}{10}}\\\\=x^{9/10}\\\\=x^{0.1}[/tex]
2.
[tex](\sqrt[4]{3y} )^3\\\\=((3y)^3)^{1/4}\\\\=3^{3\times \dfrac{1}{4}}\times y^{3\times \dfrac{1}{4}}\\\\=3^{3/4}y^{3/4}[/tex]
Hence, this is the required solution.
the local market is selling a pound of bananas for $0.55. if you bought 8 bananas for $1.44, what is the unit rate?
Answer:
$0.18
Step-by-step explanation:
Given that :
Number of bananas purchased = 8
Cost at which the 8 bananas were purchased = $1.44
The unit price of bananas can be obtained using the relation :
Total Cost of bananas / number of bananas
Unit price = $1.44 / 8
Unit price = $0.18
Price per unit of banana = $0.18

3. A student answers 90% of the
questions on a math exam correctly, how
many questions are on the exam?
Answer:
its kind of a vague question, it could be 9/10 or it could be 90/100 ??
Step-by-step explanation:
What is the missing value?
54
30%
100%
?
Answer:
the missing value is 18.
Step-by-step explanation:
First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.
For the equation
543=x1
The cross product is
54×1=3×x
Solving for x
x=54×13
and reducing
x=18
Solution by Proportion
Since the equation is an equality
If
3 ÷ 1 = 3
Then it is true that
54 ÷ x = 3
Solving for x
x = 54 ÷ 3
x = 18

Answer:
the area of the porch is 5 times larger
Step-by-step explanation:
Area of a rectangle = length x width
Original area = 15 x 6 = 90 square feet
length of width after it was enlarged 5 times = 5 x 6 = 30
New Area = 30 x 15 = 450 square feet
change in area = 450 / 90 = 5

Lin opened a lemonade stand during the summer. She
noticed that she sold more lemonade on warmer days.
For each day she sold lemonade, she plotted the point
(t,c), where t represents high temperature and c
represents cups of lemonade sold.
b. A computer program found that the line c= 2t - 89
is a good fit for the data. Use this equation to predict
how many cups of lemonade Lin might sell on a day
when the high temperature is 74 degrees.
c. the high temp this Sunday is expected to be 5 degrees warmer that the high temp this Saturday. using the line c = 2t - 89 how many more cups of lemonade should lin expect to sell on Sunday than Saturday? explain or show your reasoning
Answer:
59 cups ;
10 cups
Step-by-step explanation:
Given that he fitted model :
c = 2t - 89
Where, c = cups of lemonade sold ; t = high temperature
On a day when high temperature is 74 degrees ; cups of lemonade sold
Hence,
c = 2t - 89
c = 2(74) - 89
c = 148 - 89
c = 59 cups
Sunday is expected to be 5 degree warmer than on Saturday :
The number of cups sold on Sunday using the fitted model should be :
Difference in temperature between Saturday and Sunday multiplied by the slope value
Slope value from the model = 2
Temperature difference = 5
Difference in Number of cups :
2 * 5 = 10 cups
Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
Answer: 59 cups
Step-by-step explanation:
its 59 cause yea
The manufacturer of a certain brand of aluminum foil claims that the amount of foil on each roll follows a Normal distribution with a mean of 250 ft2 and a standard deviation of 2 ft2. To test this claim, a restaurant randomly selects 10 rolls of this aluminum foil and carefully measures the mean area to be ¯ = 249.6 ft2
Find the probability that the sample mean area is 249.6 ft2 or less if the manufacturer’s claim is true
Answer:
Given that the manufacturers claim is true, the probability that the sample mean area is 249.6 ft.² or less is 0.42074
Step-by-step explanation:
The manufacturer claims that mean amount of foil on each roll, μ = 250 ft²
The standard deviation of the measured amount of foil per roll, σ = 2 ft.²
The number of rolls tested by the restaurant, n = 10 rolls
The mean measured by the restaurant, [tex]\overline x[/tex] = 249.6
Taking the sample means as individual score, we have;
The z-score, of the sample mean is given as follows;
[tex]z=\dfrac{\overline x -\mu }{\sigma }[/tex]
At [tex]\overline x[/tex] = 249.6, we have;
z = (249.6 - 250)/2 = -0.2
Therefore, the probability for a mean less than or equal to 249.6, we have;
The probability, P = P(z < -0.2) = 0.42074
The probability that the sample mean area is 249.6 ft.² or less given that the manufacturers claim is true, P = 0.42074.
