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

While Diane was visiting her sister in Kingwood, she bought a bunch of balloons that was marked down 20% from an original price
shepuryov [24]

Answer:

$4.34

Step-by-step explanation:

Given the information:

  • The original price: $5
  • Discount : 20%
  • Tax: 8.5%

We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:

= the original price (100% - discount rate)

= 5(100% -20%)

= $4

  • The tax amount she need to pay is:

= The actual price*tax rate

= $4*8.5%

= $0.34

=> the total cost of the bunch of balloons :

The actual price + tax price

= $4 + $0.34

= $4.34

Hope it will find you well.

If 1 square food of grass seed = 25cents ,then how much would grass seed cost for 55,000 square feet of grass seed
vagabundo [1.1K]
Okay. So 25 cents is expressed as 0.25. it is $0.25 for a square foot of grass seed. To find the cost for 55,000 square feet of grass seed, all you have to do is multiply the cost per square foot by the amount of square feet total. In this case, we would multiply 55,000 by 0.25. 55,000 * 0.25 is 13,750. There. The total cost would be $13,750.

weight A weighs 50 pounds. weight B weighs 100 pounds. if A is placed 6 feet from the pivot, how far must B be placed from the p
Anit [1.1K]

To achieve balance, the momentum on both sides must be equal so that it cancels out. Momentum is simply the product of mass and distance, therefore:

 

50 pounds * 6 ft = 100 pounds * X

X = 3 ft

 

Hence B must be placed 3 ft from the pivot.

The graph shows the cost of grapes at a grocery store. What is the slope of the line?
Marysya12 [62]

The slope of the line shown in the graph is 4.5 .

In the question ,

it is given that ,

the amount of grapes is represented on x axis . and

the cost for that grape in the grocery store is represented on y axis .

to find the slope we need two points on the line ,

from the graph we can take two points as (1 , 4.5) and (2 , 9) ,

the slope can be calculated using the formula

slope = (change in y coordinate)/(change in x coordinate)

slope = (9 - 4.5)/(2 - 1)

slope = 4.5/1

slope = 4.5 .

Therefore , The slope of the line shown in the graph is 4.5 .

The given question is incomplete , the complete question is

The graph below shows the cost of grapes at a grocery store. What is the slope of the line?
