Answer:
C = $137.50
Step-by-step explanation:
Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.
Now, let's make an equation:
C = 50 + 25(3.5)
Now, multiply 25 and 3.5 together:
C = 50 + 87.5
Now we just combine the like terms:
C = $137.5
Hope this helps :)
For this case we have that by definition, the area of a triangle is given by:

Where:
b: It is the base of the triangle
h: It is the height of the triangle
According to the statement data we have:

Substituting we have:

We divide between 2 on both sides:

We factor by looking for two numbers that, when multiplied, are obtained -88 and when added together, +3 is obtained.
These numbers are +11 and -8.

We have two roots:

We choose the positive value.
Thus, the base of the triangle is:
Answer:
The base of the triangle is 22 units.
A polygon is a 2-dimension figure....
The sample space will be: {1, 2, 3, 4, 5, 6}
Event A is: {Rolling 1,2 or 3}
Complement of event A will contain all those outcomes in the sample space which are not a part of event A.
So, complement of event A will be: {Rolling a 4,5 or 6}
Thus option A gives the correct answer
The easiest way to do this is to multiple 7 and 3, which gives you 21. Julie will spend $21 on the gifts.
