Answer:
34 weeks
Step-by-step explanation:
As given,
Wage of 1 hour = $12
⇒1$ = hour
⇒$3000 = = 250 hour
As given,
1 week = 5 days
And he works
hour in 1 day
⇒5 days = 5× = hours
⇒1 week = hours
⇒1 hour = week
⇒250 hour = = 33.34 weeks ≈ 34 weeks
∴ we get
He has to Approximately work for 34 weeks with the extra hour per day to reach your goal.
Answer:
BA = 25π,
LA = 25√2π,
TA = 25π + 25√2π,
V = 41 and 2 / 3π
Step-by-step explanation:
We need to determine the height here, as it is not given, and is quite important to us. The height is a perpendicular line segment to the radius, hence forming a 45 - 45 - 90 degree triangle as you can see. Therefore, by " Converse to Base Angles Theorem " the height should be equal in length to the radius,
( Height = 5 inches = Radius
______
Now knowing the height, let's begin by calculating the base area. By it's name, we have to find the area of the base. As it is a circle, let us apply the formula " πr^2 "
- Base Area = 25π
______
The lateral area is simply the surface area excluding the base area, the surface area having a formula of " πr^2 + πrl. " Thus, the lateral area can be calculated through the formula " πrl, " but as we are not given the slant height ( l ) we have to use another formula, -
- Lateral Area = 25√2π
______
And the surface area is the base area + lateral area -
- Surface Area
______
The volume of a cone is 1 / 3rd that of a cylinder, with a simple formula of Base * height. Therefore, we can conclude the following -
- Volume = 41 and 2 / 3π
Answer:
$19.25
Step-by-step explanation:
4/4-1/4=3/4
=3/4×40
=30-5
=25-5.75
=$19.25
Answer:
C. x + 2y = 10
-4x - y = 2
Step-by-step explanation:
A. quickest way is to plug in -2, 6 and see which one works
B. this is the other way
1. x + 2y = 10
-4x - y = 2
2. multiply 4 with x + 2y = 10 so i can get 4x + 8y = 40
i want +4x so i can cancel with the -4x in -4x - y = 2
3.
4x + 8y = 40
-4x - y = 2
--------------------
7y = 42
y = 6
4. then plug in 6 into an equation to get x
-4x - y = 2
-4x -6 = 2
-4x = 8
x = -2
