Answer:

7/15 for dime

6/15 for pennies

Step-by-step explanation:

7/15 because 7+2+6=15 and there are 7 dimes so 7/15.

6/15 because there are 15 coins and there are 6 pennies so 6/15.

15 is the total so 7 and 6 have to go over it.

HIII!!! PLEASE HELP!!! AND EXPLAIN IT TOO!!!!

Answer:

We know that the Pythagorean Theorem is a² + b² = c².  First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.

Hope this helps :-)

A company uses two vans to transport
omeli [17]

Answer:

31 seats

Step-by-step explanation:

Let x be the smaller van, and y be the larger one.

We know that y = x + 14

We also know that 2x + y = 65

If we replace y by its value in the second equation we have:

2x + (x + 14) = 65, then we solve

2x + x + 14 = 65

3x + 14 = 65

3x = 51

x = 17

We now know the smaller van has 17 seats.

To find how many seats are in the big one, we take the first equation:

y = x + 14

y = 17 + 14

y = 31

You deposit $400 into an account that pays 2% annual interest compounded quarterly.
jeka57 [31]
A.

A = 400 (1 + (0.02)/4)^4t    where t = number of years and A = amount after t years
simplifying that becomes

A = 400 (1.005)^4t

b  amount after 5 years is

400 (1.005)^(4*5)  = 400 (1.005)^20 =  $ 441.96

What percentage increase occurs in the price of a round-trip economy plane ticket from New York to London by electing to go duri
balandron [24]
To find the percent increase, you will first find the difference in price for the peak season economy and the regular economy price.

$526.3-$440.8=$85.50

Then divide the difference by the beginning price(economy).

85.50/440.8= 0.19

The percent increase is approximately 19%.
