An item is regularly priced at $45. It is on sale for 55% off the regular price.
Answer:
the answer would be $20.25

55% of 45 is 24.75 and 45 - 24.75 = 20.25
Answer:
20.25

Answer:
answer is 3 11/12
Step-by-step explanation:
1 4/6 =10/6
2 1/4=9/4
when adding fractions that are do not share a common denominatour you have to find a common multiple
which in this case is 12
so 9/4 timesed the top and the bottom by 3 gives you 27/12
and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)
Hope this helps xx
Write a linear function f with the values f(3)=2 and f(0)=6
Answer:
for f(3)=2 is y=(2/3)x
Step-by-step explanation:
y=ax
and plug x and y into the parent function.
Answer:
f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:
f(x) = -⁴/₃x + 6Write an algebraic expression for the situation.
twice a number m plus the quantity n minus 4
An algebraic expression for the situation is

A small business lost $6200 in its first year, lost $2150 in its second year, and earned $4780 in its third year. Overall, in the 3-year period, how much did the business earn or lose?
Is this the correct expression?
[(6200 - 365) + ( 2150 - 730) + (4780 + 1095)]
Answer:
-6200-2150+4780
-8350+4780
Overall, they lost $3570
Give the slope and y-intercept of the relationship shown in the table

50
25
slope: -25, y-intercept=0
slope = -1/4, y-intercept = 50
slope = 1/2, y-intercept = 25
I need help with the question!!
Answer:
slope = -1/4, y-intercept = 50
Step-by-step explanation:
x=0 y=50
x=100 y= 25
y= mx+b
b= 50
25= 100 m +50
100m = - 25
m= -1/4
where m is the slope and b is the y intercept

Quadrilateral ABCD is similar to quadrilateral A'B'C'D'. Select all statements
that must be true.
there is 4 opinion in the photo
Answer:
Option 1, 2, and 4 are correct. Option 3 is incorrect.
We can conclude that the ratios →
A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'are true.
What is similarity of triangles?Two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given is Quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
If Quadrilateral ABCD is similar to quadrilateral A'B'C'D', then we can say that all the sides and diagonals will be resized by the same scale factor of [K]. So, we can say that -
A'B'/AB = A'C'/AC is true
AD/A'D' = BC/B'C' is true
AB/CD = A'B'/C'D' is true
BD/B'D' = C'D'/CD is false.
Therefore, we can conclude that the ratios →
A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'are true.
