Help me with my math​

Mathematics

Georgia [21]4 years ago

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount invested.

P represents the principal or amount invested.

R represents interest rate

T represents the duration of the investment in years.

From the information given,

P = 10000

R = 4%

In the first year, the simple interest would be

I = (10000 × 4 × 1)/100 = $400

The compound interest in the first year is also $400

In the second year, the simple interest would be

I = (10000 × 4 × 1)/100 = $400

For the compound interest in the second year,

P = 10000 + 400 = $10400

I = (10400 × 4 × 1)/100 = $416

The table would be

Simple interest compound interest

1) 400 400

2). 400 416

Total 800 816

An online furniture store sells chairs for $150 each and tables for $400 each. Every day, the store can ship no more than 30 pie
ivolga24 [154]

Answer:

minimum of 13 chairs must be sold to reach a target of $6500

and a max of 20 chairs can be solved.

Step-by-step explanation:

Given that:

Price of chair = $150

Price of table = $400

Let the number of chairs be denoted by c and tables by t,

According to given condition:

t + c = 30 ----------- eq1

t(150) + c(400) = 6500 ------ eq2

Given that:

10 tables were sold so:

t = 10

Putting in eq1

c = 20 (max)

As the minimum target is $6500 so from eq2

10(150) + 400c = 6500

400c = 6500 - 1500

400c = 5000

c = 5000/400

c = 12.5

by rounding off

c = 13

So a minimum of 13 chairs must be sold to reach a target of $6500

i hope it will help you!

Anika [276]

Answer:

A = <u>40</u> mm^{2}

Step-by-step explanation:

The equation for finding the area of a trapezoid is A= \frac{a + b}{2}h.

In this equation, a=4, b=6, h=8.

A = \frac{4 + 6}{2}8.

4+6=10
10/2=5
5x8=40

Hope this helps!

arsen [322]

Answer:

18 square centimeters

Step-by-step explanation:

Notice that if e is the midpoint of the side CB, and angle \angle x = 45^o, then this rectangle is in fact two squares of side 3 cm put together. therefore, side CD has a length of 6 cm, and as a result, the area of the figure is given by the product base times height = 6 x 3 = 18 cm^2
