Assuming that a 90° arc has an exact length of , find the length of the radius of the circle.

1 answer:

7 0

If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π

Fill in the exact length for "s" in the formula and compute to find the radius.

You deposit $1,200.00 into an account and in three years of simple interest you have $1,380. What interest rate are you receivin

Tcecarenko [31]

Since simple interest doesn't involve compounding, the same amount gets added on every year. So, the equation for the simple interest received is $I = Prt$ , where $I$ is the total interest, $P$ is the original deposit (or "principal"), $r$ is the interest rate, and $t$ is the time passed in years.

Plugging in our values, we can solve for the interest rate:

$I = Prt$
$\$1380 - \$1200 = (\$1200)(r)(3 years)$
$\$180 = (\$1200)(r)(3 years)$
$r = .05 = \bf 5 \%$

The sum of two numbers is 61. The larger number is 13 more than the smaller number. What are the numbers?

patriot [66]

Answer: 24 and 37

Step-by-step explanation:

Let the numbers be x and y . Also let us pick x as the larger number.

From the first statement :

x + y = 61 ............................ equation 1

From the second statement :

x = y + 13 ............................equation 2

Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then

x + y = 61 becomes

y + 13 + y = 61

2y + 13 = 61

2y = 48

y = 24

Substitute y = 24 into equation 2 , then

x = y + 3 becomes

x = 24 + 13

x = 37

Therefore the numbers are 24 and 37
