Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her
to set up a beach volleyball court in their back yard. A standard beach volleyball court is approximately
26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand.
Sand A = 60Ibs = $5
Sand B = 150lbs = $12
Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer.. Answer:
For Sand A should would need:
$11.266.67
Step-by-step explanation:
From the above question, we can assume that: her court is 1 cubic foot and can be filled with 100 pounds of sand
First we find the volume of the box
52ft × 26ft × 1 ft
= 1352 ft³
100Ib = 1 ft³
1352 ft³ × 100 Ib/ft³
= 135200Ibs
Sand A = 60Ibs = $5
Hence, $1 = 60Ibs/5
= 12Ibs
To purchase enough sand using Sand A to fill the court
= 135200Ibs/12lbs
= $11.266.67

They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars. There are seven scholars on the team and they agree to each sell the same number of boxes. How many boxes will each scholar have to sell in order to raise enough money to cover the team's travel expenses?
Answer:
Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
Step-by-step explanation:
Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.
Number of scholars = 7
Total number of boxes [tex]=7x[/tex]
Total number of chocolate bars [tex]=(7x)(30)=210x[/tex]
Price of 1 chocolate bar = $2
Price of [tex]210x[/tex] chocolate bars [tex]=210x(2)=\$420x[/tex]
Also,
Total amount to be raised for travel expenses = $1680
So,
[tex]1680=420x\\x=\frac{1680}{420}\\ x=4[/tex]
Therefore,
each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Is 27.5 and 11.5 irritation or rational and why
Answer:
rational because they end
Step-by-step explanation:
Answer:
27.5 and 11.5 are both rational numbers.
Step-by-step explanation:
This is because they do not continue on forever. You know what they are. So numbers like 1, 1.5, 1.234, and 100 are rational. Numbers like pi, 1/3 (1.33333 forever) are irrational.
Approximately how deep below the ground are they capable of digging in meters?
a migrating bird flies 468 miles in 13 hours. how many miles does it fly in 3 hours?
Answer:
The answer is 108mi
Step-by-step explanation:
to solve this problem, we need to write a ratio.
[tex]\frac{468mi}{13hrs}[/tex]
to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.
[tex]\frac{36mi}{1hr}[/tex]
now we have a unit rate that represents distance covered per hour.
to solve for 3, we need to multiply the numerator and denominator by 3.
[tex]\frac{108mi}{3hrs}[/tex]
the question is asking for miles. therefore, the bird can fly 108mi in 3 hrs.
hope this helps!
Answer:
108 miles
Step-by-step explanation:
For this problem you can create a proportion:
[tex]\frac{468 miles}{13 hours}[/tex]
To find how many miles it flies in 3 hours, we need to find the unit fraction. Do this by making the denominator (bottom number) 1:
here, we must divide by 13:
[tex]\frac{468 miles}{13 hours}[/tex]÷[tex]\frac{13}{13}[/tex]= [tex]\frac{36 miles}{1 hour}[/tex]
Each hour, they fly 36 miles.
To find how many miles they fly in 3 hours, make a proportion:
[tex]\frac{36 miles}{1 hour}[/tex]=[tex]\frac{x miles}{3 hours}[/tex]
Then, solve:
use cross multiplication:
36·3=108
x·1=x
108=x
3. Each month, Arnold receives $1,050 for working part-time at his uncle's camera store.
For each camera that he sells, he earns a $125 bonus. Which equation can be used to
find Arnold's total monthly paycheck, P(x), based on the number of cameras that he
sells, x?
Answer:
$1,050*125x=P(x). I just need more characters.
Step-by-step explanation:
The equation that represents Arnold's total monthly paycheck is
P(x) = 125x + 1050.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, Each month, Arnold receives $1,050 for working part-time at his uncle's camera store so it is a constant income.
For each camera that he sells, he earns a $125 bonus.
Let P(x) be the monthly check and no. of cameras sold be x.
∴ Arnold's total monthly paycheck P(x) selling x cameras is,
P(x) = 125x + 1050.

On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent. what is the cost per message? ___ dollars
which graph best approximates Jerry's text message plan? (on the y-axis each mark is $1
The cost of each message is $0.015.
Option C graph best approximates Jerry's text message plan.
Given,
On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent.
We need to find what is the cost per message in dollars.
How do we find the unit cost of an item?We divide the total cost by the number of items.
Example: 10 pieces cost $20
1 pieces cost = $20/10 = $2
We have,
$0.30 for every 20 messages.
The cost of each message:
= $0.30/20
= $0.300
= $0.015
We can see that in the graph x-axis represents the number of messages and the y-axis represents the cost of each message.
We have,
$0.30 = 20 messages
3 x $0.30 = 3 x 20 messages
$0.90 = 60 messages.
We need a graph that has a point that intersects $0.90 and 60 messages.
We see that in the graph of Option C.
Option C graph best approximates Jerry's text message plan.
Thus,
The cost of each message is $0.015.
Option C graph best approximates Jerry's text message plan.

When x+2 = 1/5y is written in standard form, what is the value or B
Answer:
B=-1
Step-by-step explanation:
Standard form is Ax+By=C.
In this case, Ax is x, By is 1/5y, and C is +2.
To isolate the 2 (the C), subtract x from both sides of the equation:
x+2=1/5y
-x -x
2=-x+1/5y.
Now, the value of B, the x value, is -1.
