Answer:
$147
Step-by-step explanation:
so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.
in this case 122.50/100= 1.225, 1.225x20 = 24.5
24.5 + 122.50 = 147
Subtract . What is the difference in lowest terms?
One-half
Four-eighths
Three-fourths
Six-eighths
5/8 - 1/8
4/8
1/2
Hope this helps! :)
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
Answer:
$1343
Step-by-step explanation:
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
You need to turn 15% into a decimal.
Move the decimal point to the left 2 spaces.
15 ---> 1.5 ---> 0.15
Now multiply 0.15 by $1,580.
0.15 × $1,580
Which is $237.
Now subtract $1580 - $237.
Which is $1343.
Answer:
$1580*15/100=$237that is discount rate.
$1580-237=$1343 actually pay

simplify the expression
The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c
Combined likely terms,
⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3
⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12
⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12
⇒ (42/24)c + 1/12
⇒ (21/12)c + 1/12
Hence "The simplification of the given is (21/12)c + 1/12".

Question about finding intercepts from a table. Hope someone can answer!
I need help due today
Answer:
Step-by-step explanation:
y=mx+b b= y-intercept y-intercept=where the line crosses the y-axis m=slope slope== rise/run or slope formula, m=y2-y1/x2-x1
For example, number 1's slope is 5/3. On a graph, you would go up 5 (not in block, but in numerical value) and right 3. The y-intercept is -2. This is where your line starts on the graph.

1/7 of ___ is 1/35
help me plz :)
The value of unknown number would be equal to 1/5
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the unknown number.
A negative divided by a negative is positive, then;
1/7 of x is 1/35
1/35 divided by 1/7
1/7 of x 1/5 = 1/35.
x = 1/5
Therefore, The value is x = 1/5

Mr. Aba builds a circular patio with a diameter of 12 feet. He covers the patio with paving stones. The cost of the paving stones is $10.50 per square foot. To the nearest dollar, how much do the paving stones cost.
Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.
Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?
A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )
Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D

13,860.42
Which best represents the greatest amount of change that took place from one day to the next day over the four-day period?
a loss of 93.98 points
a loss of 72.47 points
a gain of 72.47 points
a gain of 93.98 points
Answer:
C) a gain of 72.47 points
Step-by-step explanation:
because on 1/28 it has 13,881.93 and the next day 1/29 it has 13,954.4
subtract 13,954.4 - 13,881.93= 72.47
72.47 is the greatest amount change
And it can’t be 93.98 because in the instructions it said one day to the next not 2 day’s in advance

Two linear functions are represented in different formats.
Function 1:
x y
0 5
2 11
5 20
8 29
Function 2: (image below)
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
Answer:
Function 1 has a greater Y intercept than that of function 2
Step-by-step explanation:
Y intercept can be found by replacing x by 0 or
x = 0 0f the given function.
in this case Function 1 has a Y intercept of 5 when x =0
on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.
you can now clearly see that
y = 5 > y = -1
---> 5>-1
so that's why we conclude that 1 has a greater Y intercept.
