Answer:

9 * l = 54

Step-by-step explanation:

You don't need to worry because you are not the smartest, everyone are different, some concepts might be difficult, but will become easy soon....

Here is the answer to your question,

area of a rectangle = length * width

( * = multiplication symbol, specifying as many feel confused )

A = l * w

Here..... A = 54 m², w = 9m

54 = l * 9 or...

9 * l = 54

Brad bought 70.030m of this chain to make a necklace, then he used 0.667m of it to make one, and how much he had left, the key word ''used'' and have left'' means subtract so all we have to do is subtract 70.030m minus 0.667m and we get the answer.

Answer: 69.363m of his chain is left.

You deposit the same $10,000 into a bank account at 4% annual interest. How long will it take for the $10,000 to compound to $30

Answer:

time = 28 years

Step-by-step explanation:

Given,

principal amount = $10,000

rate = 4%

total amount = $30,000

According to compound interest formula

$A\ =\ P(1+r)^t$

where, A = total amount

P = principal amount

r = rate

t = time in years

so, from the question we can write,

$30000\ =\ 10000(1+0.04)^t$

$=>\ \dfrac{30000}{10000}\ =\ (1+0.04)^t$

$=>\ 3\ =\ (1.04)^t$

by taking log on both sides, we will get

=> log3 = t.log(1.04)

$=>\ t\ =\ \dfrac{log3}{log1.04}$

=> t = 28.01

So, the time taken to get the amount from 10000 to 30000 is 28 years.

Answer: 10 units²

Step-by-step explanation:

We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.

We can get each triangle's area using the formula $A = \frac{1}{2}bh$
