Help Please! A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
F $71.43 G $60.00 H $51.23 J $8.75
Answers
Answer:
Option F: $71.43 is the correct answer.
Step-by-step explanation:
By the question we can observe that 35% of regular price is $25 so this information will be used to calculate the original price of the shoes.
Let
P be the price of shoes
and d be the discount
So
[tex]d = \$25\\P=?[/tex]
The discount is 35% of P so
[tex]d = 35\%\ of\ P\\25 = 0.35 * P\\P = \frac{25}{0.35}\\P = 71.42857...[/tex]
Rounding off to the nearest hundredth
The regular price is: $17.43
Hence, option F: $71.43 is the correct answer.

HELP QUICK I WILL GIVE BRAINLYIEST
Answers
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

B 33b12
C b2+120
D 51b−24
E 11b+187−2,756÷13
Answers
A & D
Explanation:
The expression 51b-24 has a value of 180 when b = 4. Therefore, option D is correct.
We need to select all the expressions that have a value of 180 when b = 4.
What is the expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Now, substitute b=4 in option A.
That is 87b−179+957÷87=87×4−179+957÷87=12.94.
Substitute b=4 in option B.
33b12=33×4×12=1584
Substitute b=4 in option C.
b²+120=4²+120=136
Substitute b=4 in option D.
51b-24=51×4-24=204-24=180
Substitute b=4 in option E.
11b+187−2,756÷13=11×4+187−2,756÷13=-194.23
Therefore, the expression 51b-24 has a value of 180 when b = 4.

Please guys help me :( A bell tower that is 60 yards tall casts a shadow 32 yards long. If a nearby windmill is
45 yards tall, how long will the windmill's shadow be?
Write your answer as a whole number or a decimal. Do not round.
Answers
Answer:
The shadow of the windmill will be 24 yards long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ A bell tower that is 60 yards tall casts a shadow 32 yards long
∴ The tall = 60 yards and the shadow = 32 yards
∵ A windmill is 45 yards tall
∴ The tall = 45 yards
→ By using the ratio method
→ Tall : Shadow
→ 60 : 32
→ 45 : x
→ By using the cross multiplication
∵ x × 60 = 45 × 32
∴ 60x = 1440
→ Divide both sides by 60
∵ [tex]\frac{60x}{60}=\frac{1440}{60}[/tex]
∴ x = 24
∴ The shadow of the windmill will be 24 yards long

what translation rule maps ABCD to A’B’C’D’ ?
Answers
The reason that I say this is because ABCD is going left 1 to get to A’B’C’D’, which is like saying the x value is moving in the negative direction by 1. There is not an up or down translation, so there would be no change in y value (0). With this being said, the translation is going <-1,0>, or option 1.
The translation rule applied to the quadrilateral ABCD is T(1,0). The correct option is B.
What is translation?A translation in mathematics moves a shape left, right, up, or down but does not turn it. The translated (or image) shapes appear to be the same size as the original shape, indicating that they are congruent.
Given that the quadrilateral is translated on the x-y plane from ABCD to A'B'C'D'.
The translation applied to the coordinates of the quadrilateral will be one unit to the right and zero units up or down.
The translation will be written as,
T ( 1 , 0 )
