Answer:
You write 75% as a decimal
which would be: 0.75
Answer:
.75 is it as a decimal
Step-by-step explanation:
When you have a percentage you always move two places to the left.
For example 67% , the decimal would be .67 ----> _6_7% the lines are showing the two places you move. Also if you have 157% as a decimal it is 1.57 always move two places to the left no matter how big the percent is!!

One yardstick for measuring how steadily—if slowly—athletic performance has improved is the mile run. In 1958, the local record for the running of a certain distance was 3 minutes, 59.3 seconds, or 239.3 seconds. In the half-century since then, the record has decreased by 0.5 seconds per year.
Answer:
They will hit 180 seconds in 118.6 year
Step-by-step explanation:
Let M be the record for the mile (in seconds)
Let x be the year after 1958
So, x=(year)-19548
We are given that In the half-century since then, the record has decreased by 0.5 seconds per year
So, slope = m = 0.5
Now we will use point slope form
y = mx+c
So, we can express M as,
[tex]M=239.3-0.5 \times x[/tex]
Now we are supposed to find when they will hit 180 seconds
Substitute M = 180 in equation
180=239.3-0.5x
x=118.6
So, they will hit 180 seconds in 118.6 year
Stock Market At the beginning of the day the stock market goes down 50 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 120 1/2 points from the at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
69 3/4
Step-by-step explanation:
The stock market goes down to 50 3/4 at the beginning of the day
At the end of the day it goes up to 120 1/2
Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows
= 120 1/2 - 50 3/4
= 241/2 - 203/4
= 279/4
= 69 3/4
Hence the total change in the stock market from the beginning to the end of the day is
69 3/4

A 12 m object is represented in a picture as being 2 cm. What is the scale?
Answer: 1:600
Step-by-step explanation:
From the question, we are informed that 12 m object is represented in a picture as being 2 cm.
To find the scale used, we needed to convert 12m to cm. Since 100cm = 1m, then 12m = 12 × 100 = 1200cm.
Therefore, a 1200cm object is represented in a picture as being 2 cm. The scale will be:
= 2/1200
= 1/600
= 1:600
This means that 1 centimeter in the picture represent 600 centimeter or 6 meters.
Can someone help me simplify this (7b2 + 7b) + (7b + 7)

Aunt Mae bakes 12 dozen muffins in 45 minutes. How long would it take her to bake 4 dozen muffins?
Answer:
15 minutes
Step-by-step explanation:
set up a proportion of dozens of muffins over minutes taken to make them. 12/45=4/x. Cross multiply to get 180=12x. 180 divided by 12 is 15.

A. Subtraction Property of Equality
B. Definition of Midpoint
C. Segment Addition Postulate
D. Symmetric Property (of= or≅)
E. Reflexive Property (of= or≅)
F. Transitive Property (of= or≅)
G. Definition of Congruence
H. Substitution Property
I. Addition Property of Equality
J. Multiplication Property of Equality
K. Division Property of Equality
As per the reflexive property two angles , lines or line segments are said to be congruent with themselves . Hence we say that QR = QR .
Clair collects seashells. At home, she has 15 shells. Every day she brings 3 back to the beach. After 5 days how many seashells will Clair have?
x= days
y= number of shells
Make a table, graph (find slope), equation, define variables, and answer the question.
The equation would be:
y = 3x + 15
1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y
2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15
3) you already defined the variables
4) 3(5)+15 = 15+15 = 30 seashells

the total cost of renting a cotton candy machine for 4 hours is $72. what equation can be used to model the total cost y for renting the cotton candy machine x hours
An equation which can be used to model the total cost (y) for renting the cotton candy machine (x) hours is y = 18x.
What is an equation?An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
What is a system of equations?A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneously.
In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let x represent the number of hours.Let y represent the total cost.Translating the word problem into an equation, we have;
y = 72/4 × x
y = 18x
