PLEASE HELP!!!!!
Vesna [10]

Answer:

$289,169.84 (to the nearest cent)

Step-by-step explanation:

Compound interest is based on the principal amount and the interest that accumulates on it in every period.

Compound Interest = P (1 + r)^n

where P = principal amount, r = annual interest rate (as a decimal), n = term, in years​

So for this problem:

P = 185000

r = 1.4 ÷ 100 = 0.015

n = 30

Therefore,  

Compound Interest = P (1 + r)^n

                                = 185000 x (1 + 0.015)^30

                                = 185000 x (1.015)^30

                                = 289169.8408...

                                = $289,169.84 (to the nearest cent)

One of the sides of a parallelogram is 4.2 cm and the altitude to that side is 3.6 cm. Find the perimeter of the parallelogram i
adelina 88 [10]
The product of side length and altitude is area. The area remains the same regardless of how you measure it.

From the first side and altitude,
.. area = side*altitude = (4.2 cm)*(3.6 cm) = 15.12 cm^2
From the second side and altitude
.. area = side*altitude
.. 15.12 cm^2 = side*(2.4 cm)
.. side = (15.12 cm^2)/(2.4 cm) = 6.3 cm

The perimeter is the sum of the measures of all sides. Opposite sides are of equal measure.
.. perimeter = 2*(4.2 cm +6.3 cm) = 21.0 cm

Salsk061 [2.6K]

Answer:

BADC

Step-by-step explanation:

-4x + 7 \geq 27  Subtract 7

-4x \geq 20  Divide both sides by -4

x \leq -5  B

3x - 10 < -25  Add 10

3x < -15  Divide by 3

x < -5  A

5(x - 2) > -15  Use distributive property

5x - 10 > -15  Add 10

5x > -5  Divide by 5

x > -1  D

x - 9 < -10  Add 9

x < -1  C

1. Tickets to a concert were $5 for children and $10 for adults. If attendance at one show was 800, and the total receipts for t
stellarik [79]

Answer:

The number of adults attended was 600

Step-by-step explanation:

Let

x ----> the number of children attended

y ----> the number of adults attended

we know that

x+y=800 -----> equation A

5x+10y=7,000 ----> equation B

Solve the system by graphing

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (200,600)

see the attached figure

therefore

The number of children attended was 200 and the number of adults attended was 600
