Answer:

zero

Step-by-step explanation:

If the same sum is received for the sale of 20 apples at price p as is received for the sale of 140 apples at price p, then we must have ...

20p = 140p

120p = 0 . . . . . . subtract 20p

p = 0 . . . . . . . . . divide by 120

The price was zero.

Answer:

Price was 1 unit of money per each 7 apples and 3 units of money per each extra apple
Each woman received 20 unit of money

Step-by-step explanation:

This is the tricky one

I think 'The Seven Apple' is the hint. Let's see what the numbers have to do with 7:

20 = 7*2 + 6
40 = 7*5 + 5
60 = 7*8 + 4
80 = 7*11 + 3
100 = 7*14 + 2
120 = 7*17 + 1
140 = 7*20 + 0

Assume each '7 apples' sold for a fixed price x and each 'extra' apple sold for a different price y. Since all add up to make same amount, we get:

2x + 6y = 5x + 5y = ... = 20x

Let x = 1, then we get y = 3

<u>So we get the sold price:</u>

20 apples cost: 2*1 + 6*3 = 20
40 apples cost: 5*1 + 5*3 = 20
...
140 apples cost: 20*1 = 20

So each apple woman got 20 units of money for their apples.

Price was 1 unit of money per each 7 and 3 units of money per each extra apple

Multiply. write the product as a mixed number. 4×5/8

just olya [345]

Answer: 2 1/2

Step-by-step explanation:

Multiply 4*5/8 and you should get 20/8

Next, find the gcf , which should be 4 and divide 20/8 by 4 and you should get 5/2 as your answer.

Last turn 5/2 into a mixed number to do so do this:

5/ 2 = 2 · 2 + 1/2

= 2 · 2/ 2

+ 1/2

= 2 + 1/ 2

= 2 1/2

PLEASE HELP AS SOON AS POSSIBLE!!!!WILL GIVE BRAINLY TO CORRECT ANSWER!!!!

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Which pair of angle measures satisfy the condition sin J = cos K? A. 15°, 40° B. 45°, 90° C. 60°, 30° D. 80°, 100° E. 70°, 110°

vaieri [72.5K]

Sin J = cos K
sin J = cos (90 - J)
K = 90 - J

sin 60 = cos (90 - 60) = cos 30

Therefore, 60°, 30° satisfy the condition sin J = cos K.
