Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.

Gavin, Harry and Isabel each earn the same monthly salary.
Each month,
Gavin saves 28% of his salary and spends the rest of his salary
3
Harry spends
of his salary and saves the rest of his salary
4
the amount of salary Isabel saves: the amount of salary she spends = 3:-
Work out who saves the most of their salary each month.
You must show how you get your answer.
Answer:
isabel saves the most of their salary each month
Step-by-step explanation:
Let us assume the Salary of Gavin, Harry & Isabel be $100
Since
Gavin saves 28%
So his saving amount is Gavin
= 28% of $100
= $28
As harry spends 3 ÷ 4 of his salary
So Harry Spenings is
= (3 ÷ 4) of $100
= $75
Now
Harry Saving is
= $100 - $75
= $25
Also the ratio between isabel saves, and spend is 3:7
3k + 7k = 10k = 100S
k = $10
Now
the amount of salary isabel saves
= 3k
= 3 × $10
= $30
Now
$30 > $28 > $25
i.e.
isabel Saving > Gavin Savings > Harry Savings
Hence, isabel saves the most of their salary each month

Casey bought 9 tickets to a concert. The total charge was $104, including a $5 service charge.
a) Write and equation you can solve to find c, the cost of one ticket.
b) Solve the equation you wrote in part a.
981
Step-by-step explanation:
Add 104$ by 5$, then, because she bought 9 tickets, multiply 9 by 109 you get 981
Enter an equation for the word sentence. Use the variable c for the cost.
Three times the cost is $27
Answer:

9(x + 10) -99
Answer:
9x - 9Step-by-step explanation:
9(x + 10 ) -99
9x + 9 × 10-99
9x + 90-999x - 9
Answer:
9(x-1)
Step-by-step explanation:
9(x + 10) - 99
=> 9x + 90 - 99
=> 9x - 9
=> 9(x-1)
Find the area and the circumference of a circle with diameter 8yd
Answer:
25.12
Step-by-step explanation:
c = 2 pi r
d = 8 so r = 4
c = 2 * 3.14 * 4
c = 25.12
Answer:
Step-by-step explanation:
Given
Diameter (d) = 8 yd
radius (r) = d/2 = 8/2 = 4
Now
Area = π * r²
= 3.14 * 4²
= 50.24 yd²
Circumference
= π * d
= 3.14 * 8
= 25.12 yd

Can someone help me out with this question as I’m completely stuck
Answer:
Step-by-step explanation:
∠BEF = ∠ABE {Alternate interior angle}
∠BEF = 60
∠EQR = ∠ BEF {Corresponding angles}
∠EQR = 60
In ΔEQR
∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}
80 + 60 +x = 180
140 + x = 180
x = 180- 140
x = 40

Given parallelogram CASE, CE = x + 23, and AS = 2x + 10, find CE
Answer:
CE = 36
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
AS = CE , substitute values
2x + 10 = x + 23 ( subtract x from both sides )
x + 10 = 23 ( subtract 10 from both sides )
x = 13
Then
CE = x + 23 = 13 + 23 = 36

Here are two similar solid toys. The ratio of surface area of toys R: surface area of toy B is 7:9. The volume of toy B is 20cm^3. Work out the volume of toy A. Give your answer to 3 significant figures 
Answer:
13.7
Step-by-step explanation:
The computation of the volume of toy A is shown below:
7 × k^2=9
k^2= 9 ÷ 7
k=√9 ÷ 7
k = 1.133893419
Now
= 20 ÷ 1.133893419³

Find the annual interest rate. $I=\$160$ , $P=\$2000$ , $t=8$ months The annual interest rate is %.
Answer:
[tex]1\%[/tex]
Step-by-step explanation:
Simple interest (I) = $160
Principal amount (P) = $2000
Time period (t) = 8 months
Let R denotes rate of interest.
Relation between simple interest, principal amount, time and rate of interest is given by [tex]I=\frac{PRT}{100}[/tex]
[tex]160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%[/tex]
Answer:
12
Step-by-step explanation:
It would be: r = I * 100 / P * R
r = 160.67 * 100 / 2000 * 2/3
r = 16067*3 / 4000
r = 48201 / 4000
r = 12
