Simplify 10 + (8 ÷ 2)3.

Answers

The simplified value of 10 + (8 ÷ 2)3 is 22.

To simplify the expression 10 + (8 ÷ 2)3, we need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Solve inside the parentheses first: (8 ÷ 2) = 4

Step 2: Multiply the result by 3: 4 * 3 = 12

Step 3: Add 10 to the result: 10 + 12 = 22

So, 10 + (8 ÷ 2)3 simplifies to 22.

Following PEMDAS ensures that we perform the operations in the correct order. First, we address the expression inside the parentheses, then we deal with the multiplication outside the parentheses, and finally, we handle the addition.

In conclusion, the simplified value of 10 + (8 ÷ 2)3 is 22.

Tanyas boyfriend gave her a box of chocolates for valentines day. 3/4 of the chocolates were milk chocolate. 1/8 of them were white chocolate and the rest were dark chocolate. how many dark chocolate were in the box if there were a total of 16 chocolates in all?

Answers

3/4 of 16 is 12.

16-12=4

1/8 of 16 is 2.

12 of them are milk, 2 of them are white. If you know how many are white, the amount for the other is obvious because it's the same fraction.

2 are dark chocolate

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 32,800. If the population growth follows a linear model, what is the projected population for 2015?

Answers

Well,

the rate is (32,800 - 18,000) = 14,800 per 5 years
therefore :
in 2015 = 2010 + 5 years
the pop. will be :
32,800 + 14,800 = 47,600

Which decimal is equal to 1/5

A. 0.2

B. 0.15

C. 0.1

D. 1.50

Answers

If you do 1 literally divided by 5, because that's basically what it's asking for, you get .2, so it's A

1/5 can also be replaced as 20/100 you just multiply the denominator and numerator by 20. I think it is easier this way because decimals are out of 100 so if you can find an equal fraction that is out of 100 for the denominator the numerator can be turned into decimal form
