Sofia has 25 coins in nickels and dimes in her pocket for a total of $1.65 how many of each type of coin does she have?

Simora [160]

Answer:

She has 23 nickels and 5 dimes.

Step-by-step explanation:

Let n = the number of nickles and d = the number of dimes.

The number of each = 28. Set up the equation:

n + d = 28

Solve for n:

n = 28 - d

The total amount is $1.65 or 165 cents:

5n + 10d = 165

Substitute:

5(28 - d) + 10d = 165

140 - 5d + 10d = 165

140 + 5d = 165

5d = 165 - 140

5d = 25

d = 5, the number of dimes.

Solve for n:

n = 28 - d

n = 28 - 5 = 23, the number of nickles.

Proof:

5n + 10d = 165

5(23) + 10(5) = 165

115 + 50 = 165

165 = 165

In a right triangle, the measures of the two smaller angles are (3x+6) and (2x - 1)º. Find the measure of the smallest

Scilla [17]

Answer:

B is the answer

Step-by-step explanation:

Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.

$3x + 6 + 2x - 1 = 90$

$5x + 5 = 90$

$5x = 85$

$x = 17$

Plug 17 into both to find the smaller angle

$3(17) + 6 = 57$

$2(17) - 1 = 33$

$33 < 57$

So 33 is the answer or B

To pay off an insurance settlement you must make monthly payments of $2500 for 6 years. How much should you invest in an account

ANEK [815]

Answer:

The principal which should be invested in account is $125,698.324

Step-by-step explanation:

Given as :

The monthly payment amount = $2500

The time period = 6 years = 6 × 12 = 72 months

So, The payment for 72 months = $2500 × 72 = $180,000

The rate of interest compounded monthly = 6%

The investment amount in account = P

Now,<u> From compounded method </u>

Amount = Principal × $(1+\frac{Rate}{12\times 100})^{12\times Time}$

$180,000 = P × $(1+\frac{6}{12\times 100})^{12\times 6}$

Or, $180,000 = P × $(1.005)^{72}$

Or, $180,000 = P × 1.432

∴ P = $\frac{180,000}{1.432}$ = $125,698.324

Hence The principal which should be invested in account is $125,698.324 . Answer
