Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant rate. At this rate, how many square meters can she wax per hour?
Answer:
33.3m^2
Step-by-step explanation:
If Jessica waxes 20 m^2 of the floor in 3/5 of an hour, then;
20m^2 = 3/5 hr
To get the area that she waxes in an hour
x = 1 hr
Divide both expression
20/x = 3/5
3x = 20 * 5
3x = 100
x =100/3
x = 33.3m^2
Hence she can wax 33.3m^2 in an hour

what is the factored form of -4/5(30x - 40) + (42x + 4)?
Answer:
18(x + 2)
Step-by-step explanation:
-4/5 ( 30x - 40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)
Answer:
18x+36
Step-by-step explanation:
1. Simplify \frac{4}{5}(30x-40)54(30x−40) to \frac{4(30x-40)}{5}54(30x−40).
-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4
2. Factor out the common term 1010.
-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4
3. Simplify 4\times 10(3x-4)4×10(3x−4) to 40(3x-4)40(3x−4).
-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4
4. Simplify \frac{40(3x-4)}{5}540(3x−4) to 8(3x-4)8(3x−4).
-8(3x-4)+42x+4−8(3x−4)+42x+4
5. Expand by distributing terms.
-(24x-32)+42x+4−(24x−32)+42x+4
6. Remove parentheses.
-24x+32+42x+4−24x+32+42x+4
7. Collect like terms.
(-24x+42x)+(32+4)(−24x+42x)+(32+4)
8. Simplify.
18x+3618x+36
hope this helps

Triangle ΔGHI with m∠G = 5°, m∠H = 75° and m∠I = 100°, is reflected across the y-axis to obtain ΔKLM. What is the measure, in degrees, of ∠L?
Answer:
[tex]\angle L = 100^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle G = 5^{\circ}[/tex]
[tex]\angle H = 75^{\circ}[/tex]
[tex]\angle L = 100^{\circ}[/tex]
Required
Determine the measure of L after reflection across x-axis
When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.
In other words, the measures of the angle will not change.
Hence:
[tex]\angle L = 100^{\circ}[/tex]
Write the equation of the line.
Answer:
y=2x+4
Step-by-step explanation:
First find out the slope, pick out 2 points. For ex. (-2,0) & (0,4)
Slope=4-0/0-(-2)
=4/2
=2
Y-intercept is 4.
Slope-Intercept form: y=mx+b
m is slope & b is y-intercept
y=2x+4

What is the range of possible sizes for side x in triangle side lengths of 8.0 and 4.0?
Answer:
4<x<12
Step-by-step explanation:
8.0+4.0=12.0
8.0-4.0=4.0 or 4
The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12
So therefore , 4< x < 12

Step-by-step explanation:
A rectangular garden is 5m longer
than it is wide.
The area of the garden is 600m2
Calculate the width and length of the garden.
Answer:
The width of the garden is 22.12 m and its length is 27.12 m
Step-by-step explanation:
Equations
Let x = width of the garden
The length is 5 m longer than the wide, thus:
x + 5 = length of the garden
The area of the rectangular garden is
A=x(x+5)=600
Operating:
[tex]x^2+5x-600=0[/tex]
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Where a=1 b=5 c=-600:
[tex]\displaystyle x=\frac{-5\pm \sqrt{5^2-4(1)(-600)}}{2(1)}[/tex]
Operating:
[tex]\displaystyle x=\frac{-5\pm \sqrt{25+2400}}{2}[/tex]
[tex]\displaystyle x=\frac{-5\pm \sqrt{2425}}{2}[/tex]
There are two solutions:
x = 22.12
x = -27.12
The negative solution is not valid because x is the width of the garden, thus
x = 22.12 m
And
y = 22.12 + 5 = 27.12 m
The width of the garden is 22.12 m and its length is 27.12 m
When solving the equation, which is the best first step to begin to simplify the equation?

The price of a pair of Jordans was reduced from $200 to $160. By percentage was the price reduced
help me
Answer:
20%
Step-by-step explanation:
The Jordans was reduced by 20% from $200 to $160.
1. Subtract 160 from 200 to find out the difference:
200 - 160 = $40
2. Since $40 was the difference. Divide 40 by 200 to find out the percentage:
40/200 = .2 = 20%
3. You can check this answer: 200 x .2 = 40.
