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!!

If a stone tower is 15 meters tall and casts a shadow 8 meters long, then how long of a
shadow will be cast by a nearby radio tower that is 60 meters tall?
Answers
Answer:
32 meters long (please double-check! sometimes ppl make mistakes)
Step-by-step explanation:
the ratio of height to shadow length is 15:8, as established in the first sentence. if both sides of the ratio are multiplied by 4 then the ratio becomes 60:32.
more in depth:
if you think of it as fractions (which ratios can be written as) multiplying both the numerator and denominator by four is the equivalent of multiplying by 4/4 aka 1 so the value still stays the same (one times something is the same thing). since the ratio of height to shadow length is constant we needed to solve for the ratio in which the height is 60, so multiply each side by 4 (aka 60 divided by 15) to find the new ratio, 15(4):8(4) or 60:32. the ratio 60:32 describes height to shadow, so while the height is 60 (said in the problem) then the shadow length is 32. adding units, the answer would be 32 meters.

10x − 6 = 24
Answers
Answer:
3
Step-by-step explanation:
10x-6=24
10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)
10x= 30
x= 30/10
x= 3
The answer is 3.
Answer:
x=3
Step-by-step explanation:
10x-6=24
Subtract 6 from 6 and then add 6 to 24
10x=30
30÷10=3
Divide 30 by 10
x=3

Answer:
It’s E. 64%
Step-by-step explanation:
Based on the number of people who had a car and the total number of people surveyed, the percentage is E. 64%
Percentage of those with carsThe percentage of students with a car is:
= Number of students with cars / Number of students in total x 100%

The solution to the problem is ...
x/2 +x/6 = 2
x(1/2 +1/6) = 2 . . . . working using the given fractions
x(3/6 +1/6) = 2
x(4/6) = 2
x(2/3) = 2
x = (3/2)(2)
x = 3

What is the slope of the line?
Answers
The points represented by the table lie on a line, then the slope of the line would be; 3.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Since the Slope of parallel lines is the same. Slopes of perpendicular lines are negative reciprocals of each other.
Using any two pairs from the table of values given which are; (-4, 2) and (-3, 5):
[tex]m = \dfrac{y-q}{x-p}[/tex]
Now Plug the value into the slope formula:
m = (5 - (-4))/ (5 - 2)
m = 9/3
m = 3
Therefore, the slope of the line would be; 3.

i know she graphed it correctly but i don't know the steps she took to graph it
Answers
She graphed it correctly.
The inequality [tex]3y \le 2x[/tex] is the same as [tex]y \le \frac{2}{3}x[/tex] after dividing both sides by 3 to isolate y.
From here you graph [tex]y = \frac{2}{3}x[/tex] which is a straight line through (0,0) and (3,2). This line is made solid because of the "or equal to" as part of the inequality sign above.
We shade below the solid boundary due to the "less than" portion of the inequality sign.

Answers
Step-by-step explanation:
Table B has a proportionality relationship.Treat the values in table as (x,y) values to be plotted on a graph tool.The result is a linear function with a positive slope of 0.030.The constant of proportionality is 0.030.Given;
Volume cost($)
16 1.49
20 1.59
30 1.89
Then you have ordered pairs of points as (16,1.49) ,(20,1.59), (30,1.89) .Using a graph tool, the results is a linear graph. Find the slope of the graph as;
m=Δy/Δx
For points (16,1.49) ,(20,1.59)
m=1.59-1.49/20-16
m=0.10/4 = 0.025
You notice that the expression for the relationship is;
cost($)= 0.025* Volume +1.09
y=0.025x+ 1.09 where the y-intercept is obtained by extrapolation of the line.

What is order of operation?The order of Operations is the rule in math that states we evaluate the parentheses/brackets first, the exponents/the orders second, division or multiplication third (from left to right, whichever comes first), and the addition or subtraction at the last (from left to right, whichever comes first). In math, there might be several operations to be done while evaluating an expression, and simplification at the end yields different results. However, we can only have one correct answer for any sort of expression. To identify the correct answer we simplify any given mathematical expression using a certain set of rules. These rules revolve around all the basic operators used in maths. Operators such as addition (+), subtraction (-), division (÷), and multiplication (×).
The order of operation can be termed as BODMAS.
