Find the simple interest paid to the nearest cent for each principal, interest rate, and time. $570,2%, 4 years.

1 answer:

6 0

The answer is 45.6. You multiply the beginning amount to the interest rate to understand how much interest you get. Then multiply that by the amount of years the interest is gathered. 570 * .02 = 11.4 * 4 = $45.6 interest. Add this to 570 for the original amount of 615.6.

Jason bought 10 of the 30 raffle tickets for a drawing. What is the probability that Jason will win all 3 of the prizes if once

anastassius [24]

For the first drawing, there are 30 tickets altogether, and Jason
has 10 of them. The probability that one of his tickets will win is

   10 / 30 .

For the second drawing, there are 29 tickets altogether, and Jason
has 9 of them. The probability that one of his tickets will win is

   9 / 29 .

For the third drawing, there are 28 tickets altogether, and Jason
has 8 of them. The probability that one of his tickets will win is

   8 / 28 .

The probability that all three of these things will happen is

(10/30) x (9/29) x (8/28) = 720 / 24,360

   = 6 / 203 = 2.96 percent (rounded)

What is the perimeter of a rectangle if the length is (3x + 2) and the width is (2x - 5)

Vikki [24]

Answer: 10x-6

Step-by-step explanation:

we know that perimeter P is 2L+2W

2L= 2(3x+2)=6x+4

2W=2(2x-5)=4x-10

P=6x+4+4x-10=10x-6

In a different dimension, cows have $x+3$ legs, with 3 toes on each leg. Chickens have $2x-4$ legs, with 7 toes on each leg. If

Juli2301 [7.4K]

Answer:

20x-10

Step-by-step explanation:

Cows have $x+3$ legs and 3 toes on each leg, if we want to find the number of toes of ONE cow we have to multiply the legs by the toes giving the following:

$3(x+3) \quad (1)$

But we have two cows so (1) we have to multiply it by 2 giving a total of:

$2(3(x+3))\\6(x+3)\\6x+18 \quad (2)$

By the other hand chickens have $2x-4$ legs and 7 toes on each leg, if we want to find the number of toes we have to multiply the legs by the toes giving the following:

$7(2x-4)\\14x-28 \quad (3)$

To find the total amount of toes we have to add (2) and (3)

$(6x+18)+(14x-28)\\20x-10$

The hyperbola with center at (4, 5), with vertices at (0, 5) and (8, 5), with b = 2.

galina1969 [7]

The standard form of hyperbola is:
(x-h)²/a²-(y-k)²/b²=1
center:(4,5)
Length of the horizontal transverse axis: 8-5=3=2a
thus
a=3/2
a²=9/4
b=2
b²=4

Hence the equation will be:
(x-4)²/(9/4)-(y-5)²/4=1
simplifying this we get:
[4(x-4)²]/9-(y-5)²/4=1
