WalMart offered a 15% discount off the regular price of a Ice Cream Maker. The amount of the discount is $5.00. What is the regular price of the Ice Cream Maker?
Answer:
$33.33
Step-by-step explanation:
We are told in the above :
WalMart offered a 15% discount off the regular price of a Ice Cream Maker.
The amount of the discount is $5.00.
The formula for Percentage Discount =
Discount/Original amount × 100
Original amount = x
Hence:
$5/x × 100 = 15%
= 5/x = 15/100
Cross Multiply
5 = 0.15 × x
5= 0.15x
x = 5/0.15
x = $33.33
Therefore, the regular price of the Ice Cream Maker is $33.33
Three cylinders have a volume of 2826 cm. Cylinder A has a height of 900 cm. Cylinder B
has a height of 225 cm. Cylinder C has a height of 100 cm. Find the radius of each cylinder.
Use 3.14 as an approximation for T.
Answer:
the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
Step-by-step explanation:
The computation of the radius of each cylinder is shown below:
As we know that
The Volume of the cylinder = πr^2h
The radius would be
[tex]=\sqrt{ \frac{V}{\pi h} }[/tex]
For cylinder A
[tex]=\sqrt{\frac{2826}{3.14\times 900} }[/tex]
= 1 cm
For cylinder B
[tex]=\sqrt{\frac{2826}{3.14\times 225} }[/tex]
= 2 cm
For cylinder C
[tex]=\sqrt{\frac{2826}{3.14\times 100} }[/tex]
= 3 cm
Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
The area of a rectangle is represented by 63x^{3}+9x and the length is represented by 7x^{2}+1 . Find the width of the rectangle in terms of x.
Answer:
Step-by-step explanation:
[tex]7x^{2} +1 = 15x[/tex] and [tex]63x^{2} +9x= 135x[/tex]
so, divide because to solve for area you multiply so the opposite of multiplication is division, Anyway so [tex]135x/15x=9x[/tex]
Hope this helps.

Answer:
(x+4)^2+(y-3)^2 = 85
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the center
r iis the radius
Get the radius
Radius is the distance between the two points
r^2 = (-3-3)^2 + (3-(-4))^2
r^2 - (-6)^2+(7)^2
r^2 = 36+49
r^2 = 85
Substitute (-4, 3) and r^2 = 85 into the formula
(x-(-4))^2 + (y-3)^2 = 85
(x+4)^2+(y-3)^2 = 85
This gives the required equation
Alex needs to fill up his fish tank with water. If the tank is 8 wide,9 long and 12 tall, how much water is required to fill the tank ?
Answer:
864 gallons, or whatever measurement, of water are required.
Step-by-step explanation:
You just have to find the volume of the fish tank, which is length x width x height. So, 8 x 9 x 12 which equals 864.

Step-by-step explanation:
ayo um can i get help Please just show your work and tell what the area is
Answer:
320 inches
Step-by-step explanation:
First, split the figures into 2. 1 short rectangle and long rectangle.
Find the area of the longer rectangle first.
Length = 16 + 8 = 24 in
Breadth = 16 - 8 = 8 in
Formula for area of rectangle = Length x Breadth
24 in x 8 in = 192 in (Area of long rectangle)
Find the area of the short rectangle.
Breadth = 16 - 8 = 8 in
16 x 8 = 128 in (Area of short rectangle)
Since they're combined,
192 + 128 = 320
I don't know if this is correct, but I hope it was helpful)

Mindy looks outside her window and sees limp tomato plants in the garden. She quickly waters the plants, and by the end of the day, the plants are upright with firm stems. How did watering the tomato plants straighten the stems?
Answer:
Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

a boat travels 45 miles east then 60 miles north how far is it from where it started
Answer:
SOLUTION: A boat travels 45 miles east then 60 miles north, how far is it from where it started. Draw this. The hypotenuse of the right triangle is the square root (45^2)+(60^2)=square root of 2025=3600=square root of 5625, or 75 miles. If you divide 45 and 60 by 15, you get 3 and 4, and the hypotenuse is 5.

1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Answer:
B
Step-by-step explanation:
x- intercept = 2 .So, Coordinate(2 , 0)
y-intercept = 8 . So, Coordinate (0, 8)
[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]
Slope y-intercept form: y = mx + b {Here, b is y-intercept}
y = -4x + 8
