Wilma can walk 4 miles in 30 minutes. How many miles can she walk in 3 hours?
Answer:
24 miles
Step-by-step explanation:
3 hours = 180 minutes
[tex]\frac{4}{y}: \frac{30}{180}[/tex]
y × 30 = 4 × 180
30y = 720
30y ÷ 30 = 720 ÷ 30
y = 24

Which statement about the quadratic function m(x) = -x2 + 11x - 28 is true?
A. Since m(x) =-(x - 4)(x + 7), the zeros for m(x) are 4 and -7.
B. Since m(x) = -(x - 4)(x - 7), the zeros for m(x) are 4 and 7.
C. Since m(x) = -(x + 4)(x + 7), the zeros for m(x) are -4 and -7.
D.Since m(x) = -(x + 4)(x-7), the zeros for m(x) are -4 and 7.
Answer:
D.Since m(x) = -(x + 4)(x-7), the zeros for m(x) are -4 and 7.
Step-by-step explanation:
Answer:
Step-by-step explanation:
So first you want to take the constants of -x^2 (which would be -1) and -28 and multiply them to get the product of 28.
Since the other constant of 11x is 11, you want to find 2 numbers whose sum give you 11 and whose product give you 28. That would be 4 and 7, because 4 + 7 = 11 and 4 * 7 = 28. But since you have -x^2 you will want to put a negative sign in front of one of your x variables and in front of 4 or 7, so that you still get 11x when you factor it out.
So you would set up the equation like this (-x+4)(x-7) = 0. To make it easier to find the values of x, you could just write it out as -x+4 = 0 and x-7 = 0. Than you solve for x in botn euqations.
Then you would find out that x = 4, 7.

Answer:
My answer is 8
Step-by-step explanation:
I calculate the area of all the shapes and added them together
the square comes first = the formlula = a to the power of 2 or just L x W = 2 x 2 = 4
The traingles - the formula = the height x base/2 2 x 2 /2 = 2 ( but there are two traingles so) 2 x 2 = 4
add the two shapes areas together = 4+4 = 8

A certain company’s charges for tiling a rectangular room include the cost of the material used and a flat rate for installation. The length of a certain room is 2 feet more than its width, and the company’s charges, in dollars, for tiling the room are 12.5x(x+2) + 400.
Match each part of this expression with what it represents in this context.
Available Responses:
the width, in feet, of the room
the length, in feet, of the room
the area, in square feet, of the room
the cost, in dollars, for tile per square foot
the amount of materials needed to cover the room's floor
the flat rate, in dollars, the company charges for installation
12.5 represents ______
x(x+2) represents _______
400 represents _______
Answer:
12.5- the cost, in dollars, for tile per square foot
x(x+2)- the area, in square feet, of the room
400- the flat rate, in dollars, the company charges for installation
The length and width of the rectangular room is L = x feet , W = ( x + 2 ) feet
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangular room be A
Now , the length of the room L = x feet
And , length of a certain room is 2 feet more than its width
The width of the room W = ( x + 2 ) feet
The total charge for tiling the room C = 12.5 x ( x + 2 ) + 400
Now , the area of the rectangular room A = x ( x + 2 ) feet²
So , the width, in feet, of the room = ( x + 2 ) feet
The length, in feet, of the room = x feet
The area, in square feet, of the room = x ( x + 2 ) feet²
The cost, in dollars, for tile per square foot = $ 12.50
The amount of materials needed to cover the room's floor = 12.5 x ( x + 2 )
The flat rate, in dollars, the company charges for installation = $ 400
Hence , the expressions are solved and the area of rectangle is x ( x + 2 ) feet²

Answer:
x = 22
Step-by-step explanation:
We need to find the value of x for the given equation.
[tex]\dfrac{\dfrac{1}{5}}{\dfrac{1}{11}}=\dfrac{x}{10}\\\\\dfrac{1}{5}\times 11=\dfrac{x}{10}[/tex]
Cross multiplying both sides,
[tex]11\times 10=5x\\\\x=\dfrac{11\times 10}{5}\\\\x=11\times 2\\\\x=22[/tex]
So, the value of x is equal to 22.
