What is 0.875 simplest form

### Answers

Answer:

7/8

Step-by-step explanation:

To simplify decimals is to turn them into fractions.

As we look at our benchmarks for turning decimals into fractions, we see that 4/8 = 0.5, 6/8 = 0.75, and 8/8 = 1. But we need to figure out 7/8.

We need to figure out what is between 75 and 100.

As we subtract there will be a difference of 25.

We should divide 25 in half.

25 / 2 = 0.125, then add to 0.75, 0.125 + 0.75 = 0.875.

Therefore, in simplest form, 0.875 is 7/8 and cannot be simplified to another whole number/whole number fraction.

Best of luck to you.

A golf ball is hit with an initial vertical velocity of 80 FPS. H= -16t^2+ 80t. How high is the ball after 2 seconds

### Answers

Answer:

The height of the ball after 2 seconds = 96 feet.

Step-by-step explanation:

Given:

The height of a golf ball hit with an initial velocity of 80 FPS is given by:

where represents height of the ball in feet and represents time in seconds.

To find the height of the ball after 2 seconds.

Solution:

In order to find the height of the ball after 2 seconds, we plugin t=2 in the given function of height.

We have:

At seconds

Thus, height of the ball after 2 seconds = 96 feet.

To train for a big roce. Chelsea a runs the some route each weekday morning from-her house. She runs north for 0.75 mie and west for 1 mile. Then, she runs o straight-line home. What is the total distance Chelsea will run each week?

### Answers

Based on the information given, the total distance covered will be 15 miles.

Based on the information given, we've to calculate the hypothenuse and this will be:

- c² = a²+ b²

c² = 0.75² + 1²

c² = 0.5625 + 1

c² = 1.5625

c = √1.5625

c = 1.25 miles

Therefore, the total distance covered will be:

= 1.25 + 0.75 + 1 = 3 miles.

Therefore, the total distance covered weekly will be:

= 3 × 5

= 15 miles.

Answer:

Total distance covered on each week = 5 × 3 = 15 miles

Step-by-step explanation:

She runs north for 0.75 miles and west for 1 miles . Then she runs a straight line home. The illustration will form a right angled triangle. The straight line she runs home will be the hypotenuse of the triangle.

Using Pythagoras's formula one can calculate the hypotenuse.

c² = a²+ b²

c² = 0.75² + 1²

c² = 0.5625 + 1

c² = 1.5625

c = √1.5625

c = 1.25 miles

Total distance covered each weekday = 1.25 + 0.75 + 1 = 3 miles

Total distance covered on each week = 5 × 3 = 15 miles

Note that weekdays are Monday to Friday

Solve for z.

42 = -7 (z - 3)

z = ?

### Answers

Answer:

To solve for z you need to get it by itself and have the other half of the equal sign simplified.

42=-7(z-3)

42=-7z+21 (you would distribute the -7 through the parentheses.)

21=-7z ( you would then subtract 21 from both sides)

-3=z ( last your would divide -7 to both sides to get z by itself)

z=-3

Step-by-step explanation:

You divide by -7 on both sides then add three to both sides and the answer is -3

What is absolute value? can you solve problems using the absolute value?

### Answers

Answer:

Absolute value is a numbers distance from zero. It keeps positive numbers and turns negative numbers positive.

Yes, you can solve problems using the absolute value. For example,

|4| - |1| = 4-1 = 3

An absolute value is positive value of any value. So the abs value of -28 is 28. The abs value of 67 is 67. Makes sense?

If it were |27-3| for example, treat the inside of a abs as parenthesis, so you must complete PEMDAS inside of it to reduce the equation to |24|, unless you wanted it to become |27| - |3|.

For functions, this becomes slightly different and more difficult, especially when adding a variable such as x. Look below for a sample equation.

|2x-3|=1

This equation will actually have (and most others) 2 solutions for x. To find these, you’ll need to multiply the inside of the abs by -1 for one equation, and leave it as it is for the other!

2x-3=1 -(2x-3)=1

Now you have to solve BOTH equations to get your correct x-value answers.

For the first listed equation:

2x=4

x=2

For the second listed equation:

-2x+3=1

-2x=-2

x=-1

So you get the x-values -1 and 2 which both make the parent function true!
