Answer:

18 minutes

Step-by-step explanation:

Sophie can peel all potatoes in 45 minutes, in 1 minute she can peel:

  • 1/45 of all the potatoes

Simon can peel all potatoes in 30 minutes, in 1 minute he can peel:

  • 1/30 of all the potatoes

Together, in 1 minute they can peel:

  • 1/45+1/30= 2/90+3/90= 5/90= 1/18 of all the potatoes

To peel all the potatoes they need:

  • 1 ÷ 1/18= 1 × 18= 18 minutes

So it will take them 18 minutes to peel all the potatoes

100 pointsPLEASE HELP SUPER TIRED!!solve the inequality. 4+|t+2|<11
dolphi86 [110]

Answer:

- 9 < t < 5

Step-by-step explanation:

Isolate | t + 2 | by subtracting 4 from both sides

| t + 2 | < 7

Inequalities of the type | x | < a always have a solution of the form

- a < x < a, hence

- 7 < t + 2 < 7 ( subtract 2 from all 3 intervals )

- 9 < t < 5

Say that you (or your parents) are purchasing a new car for $22,358. The sales tax is 6.45%, the down payment is 10% of the tota
Nastasia [14]

9514 1404 393

Answer:

  (a)  $133.88

Step-by-step explanation:

The addition of tax multiplies the purchase price by 1+6.45% = 1.0645. The payment of the down payment means the loan amount will be only 1-10% = 0.90 times the amount with tax. So, the loan amount is ...

  $22,359(1.0645)(0.90) = $21,420.08

The loan is a secured loan (secured by the vehicle). So, the interest charged is that for a poor credit rating: 7.5%.

One month's interest is ...

  I = Prt . . . . . interest on principal P at rate r for t years (1 mo = 1/12 yr)

  I = $21,420.08(0.075)(1/12) = $133.88

The correct answer will be the first one, (-1,0). Since it gives you the points the first point will be x and the second point will be y. All you have to do is plug those points into the equation and see if it is the correct answer if not go onto the next points until you reach the correct one.
