The amounts below show the change (measured in feet) in water level over four months. What is the
average monthly change in water level?
-0.84, 1.25, -1.59, 0.42

Answers

Answer 1
The average monthly change in the water level is a decrease of 0.19 feet, = -0.19

For an average, we add up the numbers and divide that total by how many “entries” we have.

So 1.25 + 0.42 - 0.84 - 1.59 = 1.67 - 2.43 = -0.76

-0.76/4 = -0.19

Answer:

perimeter

Step-by-step explanation:

perimeter is the distance around

volume is the amount it will hold

weight is  how heavy it is

area is the amount of space it covers

Answer:

Primeter

Step-by-step explanation:

So Weight is out of the question since you do not need to weigh anything

Area is the inside of the picture so that is also out

It is either primeter or volume

Volume is used to find the surface of an object, it takes up. It is used for 3-d objects, since this is not a 3-d piece it is not that.

It is the primeter since you will need to find out the side legnths to find out what frame will work.

Write the number in 2 equivalent forms as a​ fraction, decimal, or percent.
0.25
What is the equivalent​ fraction?

​(Type a whole number or a​ fraction.)
What is the equivalent​ percent?
%

Answers

The decimal 0.25 represents the fraction 25/100. Decimal fractions always have a denominator based on a power of 10. We know that 5/10 is equivalent to 1/2 since 1/2 times 5/5 is 5/10. Therefore, the decimal 0.5 is equivalent to 1/2 or 2/4


0.25 as a equivalent percentage is just 25% I’m pretty sure.

Which sentence correctly compares the two points shown on the number line? -1 > 0.25 , -1 < -0.25, -0.25 < -1

Answers

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Answer : -1 < -0.25,

Multiplying both sides by 100 and dividing both sides by 90,

we have x = 30 ×  100 / 90

x = 33.33
