-8.0 is classified as?Select all that apply * Natural Number Whole Number Integer Rational Number
grigory [225]

Answer:

Integer and Rational Number

Step-by-step explanation:

Natural numbers are positive numbers starting at 1 and going onward.  Since -8.0 is not a positive number, it is not a natural number.

Whole numbers are natural numbers and 0 altogether.  -8 is not greater than zero or positive, so it is not a whole number.

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.  -8.0 can also be written as -8/1, so it is a rational number and an integer, since every integer is a number over 1 and also a rational number.

If 3 quarts of paint are needed for 50 ft of fence, how many quarts are needed for 300 ft of fence?
Zina [86]

Answer:

18

Step-by-step explanation:

First, you would do a proportion

\frac{3}{50}=\frac{x}{300}

Then you would cross multiply, getting 50x=900.

After that, you would do 900/50, which is 18.

Previous studies on sleep tendencies report that, on average, an adult American will sleep for 6 hours each night with a standar
Tom [10]

Answer: One sample z test for means

Step-by-step explanation:

From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = population standard deviation

The probability value would be determined from the normal distribution table.

Therefore, the hypothesis test that should be used is

One sample z test for means

An electrician has 4.1 meters of wire how many strips 7/10 m can he cut . How much wire will he have left
kogti [31]
7/10 m= 0.7 m

4.1÷0.7=5.85 

You would round down 5.85 to just 5, because he cannot cut less than a whole strip.

To find the exact amount of wire used in 5 strips:

5×0.7= 3.5

4.1-3.5= 0.6 m will be leftover.

How long can the run be made?
defon

Answer:

L=15\ m

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

P=2L+2W

In this problem we have

P=42\ m

W=6\ m

substitute in the formula and solve for L

42=2L+2(6)

simplify

21=L+(6)

L=21-6=15\ m
