if you work 35.6 hours and get paid $7.85 a hour how much is that in total
Answers
Answer:
$279.46
Step-by-step explanation:
to solve this equation you have to multiply 35.6 to 7.85
35.6 * 0.05 = 1.78
35.6 * 0.8 = 28.48
35.6 * 7 = 249.2
1.78 + 28.48 + 249.2 = $279.46

Jen ran directly toward school at a constant velocity for 36 seconds. In one-third of that time, she ran 120 meters. What was her velocity?
Answers
Answer is 10 m/s
Step-by-step explanation:-First, we need to calculate one-third of 36 seconds :
[tex] \frac{1}{3} \times 36[/tex]
[tex] \frac{36}{3} [/tex]
[tex]12[/tex]
Now, to find velocity, let's divide the distance by time :
[tex]velocity = \frac{distance}{time} [/tex]
[tex]velocity = \frac{120}{12} [/tex]
[tex]velocity = 10 \: m/s[/tex]
Therefore, Jen's velocity is 10 m/s .

The perimeter of a rectangle is 34 units. Its width is 6.5 units.
1. Write an equation to determine the length (l) of the rectangle.
2. Find the length of the rectangle.
Answers
Answer:
10.5 unitsStep-by-step explanation:
Given
Perimeter P = 34 unitsWidth w = 6.5 unitsLength l = ?Equation, in terms of l:
2(l + 6.5) = 34l + 6.5 = 17l = 17 - 6.5l = 10.5Answer:
Equation:6.5 + 6.5 + L +L =34
Answer: 10.5
Step-by-step explanation:
To find perimeter you need L+W+L+W. You have a width of 6.5. When you plug that into the equation you get 6.5 + 6.5+ L+L=34. Combine like terms (6.5 +6.5). That leaves you with 13 + 2L = 34. Now, you want to subtract 13 from both sides to isolate the L. You now have 2L = 21. Now you should divide everything by 2. 21/2 = 10.5

If JM=30 and LM=8, what is KM?
Answers
If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.
How to determine the length of side KM?In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;
Side JL = [(30 + 8) × x]/2
Side JL = 38x/2
Side JL = 19x.
Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;
19x = √[(30² + x²)(x² + 8²)]/2
38x = √[(30² + x²)(x² + 8²)]
By taking the square of both sides, we have:
38²x² = (900 + x²)(x² + 64)
38²x² = 900x² + 57,600 + x⁴ + 64x²
38²x² = 964x² + 57,600 + x⁴
(x² - 240)² = 0
x² = 240
x = √240
x = 15.49 units.

PLS MARK BRAINLIEST
Step-by-step explanation:
m= y2 - y1/ x2 - x1( slope of a line)
m = 8 -0 / 7- 0
8/7 = m
m = 1.1
since m =y - y1/ x - x1
1.1 = y - 0/ x-0
1.1 = y/x(cross multiply)
y = 1.1 x
y -1.1 x = 0
or
y - 8/7 x = 0
