Answer:
Hours of work= 3.5
Step-by-step explanation:
Giving the following information:
Allowance= $5
Hourly pay= $7.5
Desired profit= $31
<u>To calculate the number of hours to work, we need to use the following formula:</u>
Hours of work= shoveling pay / hourly pay
Hours of work= (31 - 5)/7.5
Hours of work= 26/7.5
Hours of work= 3.5
<h3>
Explanation:</h3>
There is a theorem :
Proof: open the brackets on right side of equality by using distributive property
RHS = a(a+b) - b(a+b)
RHS = 
RHS = 
= LHS
Using the above theorem you can solve every question you asked:
To find the answer. you have to use the pythagorean theorem.
a² + b² = c² where "a" and "b" are the legs and "c" is the hypotenuse.
24² + b² = 26²
576 + b² = 676
b² = 676 - 576
b² = 100
√b² = √100
b = 10 so 10 is the number of the second leg.
hope this helps, God bless!
Answer:
y=x-4
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
m = (1--9)/(5--5)
m = (1+9)/(5+5)
= 10/10
= 1
The slope is 1
We have the slope and a point,so we can use point slope form
y-y1 = m(x-x1)
y-1 = 1(x-5)
y-1 = x-5
Add 1 to each side
y-1+1 = x-5+1
y=x-4
This is slope intercept form (y= mx+b)
