Answer:

Figure 1 = 94m^2

Figure 2 = 89.1

Step-by-step explanation:

Figure 1:

Break the figure into pieces and then add. 24 + 30 + 40 = 94

Figure 2:

8 * 8 = 64

then using C = 2 pi r you get 25.13

64 + 25.13 = 89.13

In 1846 the depth of the river was 2.5 feet deep. In 1847 it rose 9%. This year, 1848, it dropped 6%. How deep is the river now?

Answers

Answer:

So the answer is 2.5615 feet.

Step-by-step explanation:

So the river is 2.5 feet deep, and when you find that 9% is, using the cross-multiplication formula to find the percent then 9% of 2.5 is 0.225, and when you add that to 2.5 you get 2.725, and when you find 6% of 2.725, you get 0.1635, and since it dropped, you subtract, and you end up with 2.5615

Hope I helped

The depth of the river in 1848 is 2.5615 feet.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

The % formula is used to calculate a percentage of a whole in terms of 100. You may use this formula to express a number as a fraction of 100. If you look closely, calculating percentages indicated above can be readily computed using the formula below:

Percentage = (Value/Total Value) × 100

To solve this problem, we can start by finding the depth of the river in 1847 after it rose by 9%.

Depth in 1847 = 2.5 + (9% of 2.5)

Depth in 1847 = 2.5 + 0.225

Depth in 1847 = 2.725 feet

Next, we need to find the depth of the river in 1848 after it dropped by 6%.

Depth in 1848 = 2.725 - (6% of 2.725)

Depth in 1848 = 2.725 - 0.1635

Depth in 1848 = 2.5615 feet

Therefore, the depth of the river in 1848 is 2.5615 feet.

Pedro bought 7 tickets to a basketball game. He paid a total of $147. Enter an equation, using x as your variable, to determine whether each ticket cost $21 or $22. Then enter the cost of the ticket.

Answers

Answer:

7 . x = 147

Step-by-step explanation:

7 • x= 147
7 multiplied by x equals 7x
( 7•x=7x)
then you need to get rid of the 7 so you divide by 7 on both sides.
(7x/7=x) (147/7=21)
x=21
