Answer 1
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!

restaurant serves three types of omelettes. Surveys were taken of the last two days of orders and are displayed in the table below. Approximately 200 omelettes are served each day. What is the average number of ham and cheese omelettes served each day?
Answers
120 is the average number of ham and cheese omelettes served each day.
What is Statistics?
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that a restaurant serves three types of omelettes.
ham and cheese , Mexican and Vegeterian.
We have to find the the average number of ham and cheese omelettes served each day.
In survey 1, ham and cheese served are 7 out of 12 and in survey 2 they are 11 in number out of 18.
7/12 of 200
7/12×200=116.67
11/18 of 200
11/18×200=122.22
Average=116.67+122.22/2
=120 per day.
Hence, 120 is the average number of ham and cheese omelettes served each day.
