Alicia´s gross monthly pay is 1,700. Alicia pays 1.25% of her monthly salary for Medicare. how much dose she pay
Answer:
$21.25
Step-by-step explanation:
1700 x 1.25% = 1700 x 0.0125 = 21.25
So Alicia's paying $21.25 of her monthly salary to Medicare.
Answer:
$21.25
Step-by-step explanation:
If Alicia´s gross monthly pay is 1,700 and she pays 1.25% of her monthly salary for Medicare, she would pay $21.25.
In order to find this, you must multiply the gross monthly pay by the percent.
1,700 x 1.25 = 21.25

Answer:
y = -5
Step-by-step explanation:
To solve this, we simply plug in 4 into x and then solve for y. We have:
[tex]-3x+9y=-57\\[/tex]
Now we put 4 into x and do some algebra and solve for the value of y:
[tex]-3x+9y=-57\\-3(4)+9y=-57\\-12+9y=-57\\9y=-57+12\\9y=-45\\y=\frac{-45}{9}\\y=-5[/tex]

A box is 8 1/2 inches wide 12 3/4 inches long in 5 1/2 inches tall what is the total surface area of 3 such boxes
Step-by-step explanation:
Surface Area Formula: SA=2lw+2lh+2hw
SA is surface area. l is length, w is width, h is height. Make sure to follow PEMDAS and keep multiplication together before adding.
Now substitute values
2(12 3/4*8 1/2)+ 2(12 3/4 * 5 1/2)+ 2(5 1/2*8 1/2)
SA=450.5 inches squared
To find the total surface area of three identical boxes with given dimensions, calculate the surface area of one box using the formula for a rectangular prism and then multiply by three. The total surface area of three boxes is 1351.5 square inches.
Calculating the Total Surface Area of Three Boxes
The question involves finding the total surface area of three identical boxes, each with the dimensions 8 1/2 inches wide, 12 3/4 inches long, and 5 1/2 inches tall. To calculate the surface area of one box, we use the formula for surface area of a rectangular prism:
SA = 2lw + 2lh + 2wh
where SA is the surface area, l is the length, w is the width, and h is the height. Convert fractions to decimals for easy calculation:
Width (w) = 8.5 inches
Length (l) = 12.75 inches
Height (h) = 5.5 inches
Applying the dimensions:
SA = 2(12.75)(8.5) + 2(12.75)(5.5) + 2(8.5)(5.5)
Calculate and add up the areas for each pair of sides:
SA = 2(108.375) + 2(70.125) + 2(46.75)
SA = 216.75 + 140.25 + 93.5
Sum to find the total surface area for one box:
SA = 450.5 square inches
To find the total surface area for three boxes, multiply the surface area of one box by 3:
Total SA = 450.5 * 3
Total SA = 1351.5 square inches
The total surface area of three such boxes is 1351.5 square inches.

Petra is raking leaves in her backyard. Petra’s backyard is rectangular and has an area of 476 square feet. One side of the backyard is 28 ft. How long is the other side?
Evaluate (b+c) if a=2,b=-5 and c= -3
It’s a good idea to get into the habit of using parentheses
when substituting numbers in for variables.
If you have parentheses in your original problem, change them to brackets as you substitute (to avoid confusion).
Now plug in the values for b and c into the problem.
So we have [(-5) + (-3)].
Simplifying inside the brackets, we get [(-8)].
So -8 is the answer.

a poster is 8in by 6in what are the dimensions if the poster is enlarged by a factor of 7/2
Answer:
[tex]21\ in[/tex] by [tex]63\ in[/tex]
Step-by-step explanation:
we know that
To find the dimensions of the enlarged poster, multiply the original dimensions of the poster by the scale factor
so
[tex]18(\frac{7}{2})=63\ in[/tex]
[tex]6(\frac{7}{2})=21\ in[/tex]
therefore
The dimensions of the enlarged poster are [tex]21\ in[/tex] by [tex]63\ in[/tex]

the graphs below have the same shape. What is the equation of the blue graph?
Option: C is the correct answer.
The equation of the blue graph i.e. function G(x) is:
C. [tex]G(x)=(x+3)^2+1[/tex]
Step-by-step explanation:We are given a parent function F(x) as:
[tex]F(x)=x^2[/tex]
Now after looking at the graph of the transformed function G(x) we see that the graph of G(x) is obtained by shifting the graph of F(x) 3 units to the left and 1 units upward.
Hence, the equation of the transformed function G(x) is given by:
[tex]G(x)=(x+3)^2+1[/tex]
Otis had a salad for $4.50, a sandwich for $6.25, and a drink at his favorite restaurant. The tax for the entire meal was $0.54. What was the price of the drink?
Answer:
Price of the drink = $1.25
Step-by-step explanation:
4.5% * ( $4.5 + $6.25 + drink) = $0.54
4.5/100 * ( $4.5 + $6.25 + drink) = $0.54
0.045 * ( $4.5 + $6.25 + drink) = $0.54
0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045
( $4.5 + $6.25 + drink) = $12
10.75 + drink = $12
drink = $12 - $10.75
drink = $1.25
The price of the drink is $1.25
How to determine the price of the drink?The given parameters are:
Tax amount = $0.54
Salad = $4.50
Sandwich = $6.25
Let the price of the drink be x.
Given that the sales tax is 4.5%, we have:
4.5% * ( $4.5 + $6.25 + x) = $0.54
Divide both sides by 4.5%
( $4.5 + $6.25 + x) = $12
Evaluate the sum
$10.75 + x= $12
Subtract $10.75 from both sides
x = $1.25
Hence, the price of the drink is $1.25

Does the point (3,-1) lie on the circle (x+1)2 +(y-1)2=16?
Final answer:
After substituting the x and y values of the point (3,-1) into the circle's equation, it is determined that (3,-1) does not lie on the circle since the equation does not hold true.
Explanation:
To determine if the point (3,-1) lies on the circle given by the equation [tex](x+1)^2 + (y-1)^2[/tex]=16, we must substitute the x and y values of the point into the equation and see if the equation holds true.
Let's plug in x = 3 and y = -1:
[tex](3+1)^2 + (-1-1)^2[/tex]= 16
[tex](4)^2 + (-2)^2[/tex] = 16
16 + 4 = 20
Since 16 + 4 does not equal 16, the point (3, -1) does not lie on the circle

If point A is located at (-9,2)on the coordinate plane and point B is located at (-9,10)what is the distance between the two points?
Answer:
8 units
Step-by-step explanation:
The x coordinates don't change so you just subtract 2 from 10 to get the distance.
Answer:
8
Step-by-step explanation:
To calculate the distance d, using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 9, 2) and (x₂, y₂ ) = B(- 9, 10)
d = [tex]\sqrt{(-9+9)^2+(10-2)^2}[/tex]

A fruit punch contains 20% fruit juice is combined with 100% fruit juice how many ounces of each should be used to make 40oz of a mixture that is 60% fruit juice
Final answer:
To make a 40-ounce mixture that is 60% fruit juice, equal amounts (20 ounces each) of 20% fruit juice and 100% fruit juice should be used.
Explanation:
Calculating the Fruit Juice Mixture
To solve this problem, we'll use a system of equations. Let's assume that the amount of 20% fruit juice used is x ounces, and the amount of 100% fruit juice used is y ounces. We are trying to make 40 ounces of a mixture that is 60% fruit juice.
First, the total amount of the mixture should be 40 ounces:
x + y = 40
Second, the total percentage of fruit juice in the mixture should be 60%:
0.20x + 1.00y = 0.60 * 40
Now, let's solve these equations step-by-step:
From the first equation, we can say y = 40 - x.
Substitute y in the second equation: 0.20x + 1.00(40 - x) = 24.
Simplify: 0.20x + 40 - x = 24.
Combine like terms: 40 - 0.80x = 24.
Subtract 40 from both sides: -0.80x = -16.
Divide both sides by -0.80 to find x: x = 20.
Substitute x back into y = 40 - x to find y: y = 20.
Therefore, to achieve a 60% fruit juice mixture, 20 ounces of the 20% fruit juice and 20 ounces of the 100% fruit juice should be combined.
