Answer:
Cost of table is $237
Step-by-step explanation:
Cost of chair, table and lamp = $562
Cost of lamp = x
Cost of chair = 4x (The chair costs 4 times as much as the lamp)
Cost of table = 4x-23 (the table costs $23 less than the chair.)
We need to find the cost of table.
We know that:
Cost of chair, table and lamp = $562
We can write:
[tex]x+4x+4x-23=562[/tex]
First, we need to find value of x by solving the equation.
[tex]x+4x+4x-23=562\\9x=562+23\\9x=585\\x=\frac{585}{9}\\x=65[/tex]
So, we get x = 65
Now, we can find cost of table:
We are given:
Cost of table = 4x-23
Cost of table = 4(65)- 23 = 237
So, Cost of table is $237

Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 5 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Answer:
2 hours 15 minutes
Step-by-step explanation:
Given that :
Ben's speed = 3 mi/hr
One and half hours after Ben leaves = 1.5 hours
Ben's distance = 3 mi/hr * 1.5 = 4.5 miles
Amanda's speed = 5 mi/hr
Time taken before Amanda catches up:
Let time taken = x
Distance = speed * time
Ben's distance = Amanda's distance
4.5 mi + (3 * x) = 5 * x
4.5 + 3x = 5x
4.5 = 5x - 3x
4.5 = 2x
x = 4.5 / 2
x = 2.25 hours
Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes
It would take Amanda 2.25 hours to catch up with Ben
Speed is the ratio of distance to time. It is given by:
Speed = distance/time
Given that Ben covers a distance d at time t, hence:
3 = d/t
d = 3t
Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5
5 = d/(t - 1.5)
d = 5t - 7.5
Since they catch up, hence:
3t = 5t - 7.5
2t = 7.5
t = 3.75 hours
Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours
Hence it would take Amanda 2.25 hours to catch up with Ben.

A loan of $7,000 was approved for 36 weeks. Total amount (principal and interest) was paid as S 7388 charged with an 8% annual rate of interest. What is the value of t time in years?
Answer:
.7
Step-by-step explanation:
I'm going to assume that there will just be one final payment at the end. I am also going to discard the fact that the loan was approved for 36 weeks becuase I don't know what to do with that information
I will be using the following formula
[tex]FV=PV(1+i)^n[/tex]
Plugging in the numbers we get
7388=7000(1+.08)^n
We we divide by 7,000 and simplify what we can to get
1.0554=1.08^n
We then write the following log
log(1.0554)/log(1.08)=n
Compute this and get n= .7
A cylinder is 12 feet high and has a diameter of 10 feet. in cubic feet, what is the approximate volume of the cylinder
Answer:
300π or 942.477796077 cubic feet
Step-by-step explanation:
25π*12=300π
The approximate volume of the given cylinder is 942.48 ft³.
What is the volume of the cylinder?The volume of the cylinder is the density which signifies the amount of substance it can hold.
Mathematically,
V = πr²h
where, r is the radius of the cylinder
and h is the height of the cylinder.
It is given that,
Height h of the cylinder = 12 ft
Diameter d of the cylinder = 10 ft
⇒ Radius r = d/2
⇒ r = 10/2
⇒ r = 5 ft
Now, Volume of the cylinder V = πr²h
Putting the values of r and h of given cylinder. We get,
⇒ V = 3.14 × (5 ft)² × 12ft
⇒ V = 3.14 × 25 ft² × 12 ft
⇒ V = 3.14 × 300 ft³
⇒ V ≈ 942.48 ft³
The approximate volume of the given cylinder is 942.48 ft³.

A school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping. How much did they make selling balloons?
Answer:
OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.
Step-by-step explanation:
The school club made $298.08 by selling the balloons.
What is Profit?Profit is calculated as total revenue less total expenses.
Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.
Cost of balloons when they brought them = 1.29*150 = $193.5
Total cost = $193.5 + (shipping price) = $193.5 + $8.92
Total cost = $202.42
Cost at which they sold the balloons = 143*$3.50 = $500.5
Therefore, their total profit = $500.5 - $202.42 = $298.08
Hence, The school club made $298.08 by selling the balloons
