The time (t) required to finish a certain job is inversely
proportional to the number of persons (p) on the job. If 10
persons can finish the job in 6 hours, how long will it take
for 30 persons to finish the job?​

Answers

Answer 1

18 hours

Step-by-step explanation:

6/10=0.6 hours (one person takes 0.6 hour)

0.6×30=18 hours

or another way 10 is 1/3 of 30. so

6:1/3=18

Answers

Answer: £3200000

Step-by-step explanation:

£1000 is 100%, so 5000% is x50 (5000/100) of £1000 which is £50000. Then 64x50000 is 3 200 000. Therefore you will make £3200000 from 64 piece of wood

Answer:

Yes, there should be a solution.

Step-by-step explanation:

y = -2x + 2; slope is -2.

It is graphed at (0, 2) (1, 0)

You could write this as y = -2x

y = 2x - 6; slope is 2.

It is graphed at (0, -6) (3, 0)

You could write this as y = 2x - 6

Answers

Answer:

slope is 1

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

so m=[tex]\frac{9-2}{8-1}[/tex]

m=[tex]\frac{7}{7}[/tex]

m=1

so slope is 1

Shonda has $125. She spends 35% of the money she has on a concert ticket. How much did Shonda spend on the ticket?

Answers

Answer:

she spent $43.75

Step-by-step explanation:

you basically need 35% of $125

cool trick with this is "of" always means multiplication

35% x 125= 43.75

she spent $43.75

Shonda spent the amount of $43.75 on the concert ticket.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

To find out how much Shonda spent on the concert ticket, we can use the following proportion:

(35%) × 125 = x/1

where x is the amount of money spent on the concert ticket, and we know that 35/100 (or 0.35) is 35% of 125.

Convert percent into decimal form and solve for x:

(0.35) × 125 = x

Apply the multiplication operation, and we get

x = 43.475

Therefore, she spent $43.75 on the concert ticket.

You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$

Answers

Answer:

3/24 = 7/x

c = $56

Step-by-step explanation:

A percent proportion is just basically a ratio, I could also write this as         3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.

a/b = c/d

Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
