The 5 is in the ten thousandths place
Answer:
275 m^3
Step-by-step explanation:
The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.
First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.
In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.
Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so
V=(1/3)(75/2)*22=275
Answer:
worked 4 hours tutoring = 4 hours * $25 = $100 earned
$130 needed - $100 earned = $30 needed
$30/ $10 hour babysitting = 3 hours
as for the number of hours, 4 hrs tutor + 3 hrs babysit = 7 hrs, 7 hours < 10 hours its within the requirements
Minimum # of hours babysitting = 3 hours
Step-by-step explanation:
Answer: (B) y - 3 = 2(x - 1)
<u>Step-by-step explanation:</u>
The Point-Slope formula is: y - y₁ = m(x - x₁) where
- m is the slope
- (x₁, y₁) is any point on the line
It is given that the slope (m) is 2 and a point on the line (x₁, y₁) is (1, 3), so the equation is: y - 3 = 2(x - 1)
Answer:
Approximately to the nearest cent :
$1856
Step-by-step explanation:
We are told in the above question that:
Suzie's profit increases every month by 30%
We are told that in the first month her profit is $300
Step 1
We are to find the profit for the other weeks:
First week Profit = $300
b) Second week =
$300 × 30/100 = $90
Total amount for the second week= $90 + $300
= $390
c) Third week
$390 × 30/100 = $117
Total amount for the third week = $117 + $390
= $507
d) Fourth week
$507 × 30/100 = $152.1
Total amount for the fourth week = $152.1 + $507
= $659.1
Total Amount of money she would make after 4 weeks =
Profit of the first week + Total Amount for the first week + Total Amount for the second week + Total Amount for the third week + Total Amount for the fourth week
= $300 + $390 + $507 + $659.1
= $1856.10
Approximately to the nearest cent the amount of money will she make in all over 4 weeks is :
$1856
