Answers
Answer:
Hello! answer: 6.25
Step-by-step explanation:
With these we will cross multiply so 12.5 × 3.6 = 45 so now that we have that we can just divide by 7.2 for h! so... 45 ÷ 7.2 = 6.25 so h = 6.25 HOPE THAT HELPS and heres a visual picture

Find the surface area of the equilateral triangular pryamid.
15 cm
10 cm
Answers
Answer:
268.3 cm³
Step-by-step explanation:
Surface area of triangular pyramid = Base Area + ½*(perimeter of base)(height of pyramid)
Base area = 43.3 cm²
Perimeter of base = 10 + 10 + 10 = 30 cm
Height of pyramid = 15 cm
Plug in the values
Surface area = 43.3 + ½(30)(15)
Surface area = 43.3 + 225
= 268.3 cm³

Answer:

Step-by-step explanation:
In the formula for volume of a right cone, solve for the variable k: V = 1/3 * pi * r ^ 2 * h Note: In this formula, V is volume, h is height, and r is radius of the base of the cone
A. h = (3r ^ 2 * V)/pi
B. h = (3V)/(pi * r ^ 2)
C. h = (3pi * V)/(r ^ 2)
D. h = v/(3pi * r ^ 2)
Answers
The height of the cone can be written as h = 3V/(π × r²).
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The formula for the volume of cone is given as V = 1/3 × π × r² × h.
It can be written in terms of h by the method of solving a linear equation as follows,
V = 1/3 × π × r² × h
=> 3V = π × r² × h
=> h = 3V/(π × r²)
Hence, the expression for height from the given formula can be written as h = 3V/(π × r²).

On Monday, Courtney spent 14 minutes solving 1 math problem and 2 biology problems. On Tuesday, Courtney spent 16 minutes solving 2 math problems and 1 biology problem. Write and solve a system of equations to find how long it takes Courtney to solve each math problem and each biology problem
Answers
Answer:
the timing taken to solve each math problem and each biology problem is 4 minutes each respectively
Step-by-step explanation:
Let us assume the timing taken for math problem be x
And, the time taken for biology problem be y
Now as per the question
The following equations should be considered
x + 2y = 14 .............(1)
2x + y = 16. ...................(2)
Multiply by 2 in equation 1
So,
2x + 4y = 28
2x + y = 16
3y = 12
y = 4 minutes
So, x = 14 - 2(4)
= 12 - 8
= 4 minutes
hence, the timing taken to solve each math problem and each biology problem is 4 minutes each respectively

The maximum number of pounds p is 224
Step-by-step explanation:
Let
p ----> the maximum number of pounds he can pull without going over the weight limit
we know that
121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds
In this problem the word "at most" means "less than or equal to"
so
The inequality that represent this situation is
solve for p
subtract 121 both sides

Answer:
615.75
Step-by-step explanation:
SP and Enrich are water pump manufacturers. SP claims that its water pumps have a higher maximum discharge flow rate than Enrich water pumps with the same specifications. To test the claim, a consumer bureau selected 10 water pumps from each manufacturer by visiting the distribution sites of both SP and Enrich and blindly selecting one water pump from 10 different lots at their sites. The consumer bureau found that, on average, SP water pumps had a 4% higher maximum discharge flow rate than Enrich water pumps. Given the bureau’s data collection method and report, what conclusion can be made?
A. The collection method was unfair because SP's claim may have influenced the bureau's report.
B. The collection method was random because the selection process ensured a random representation of each manufacturer's water pumps.
C. The collection method was fair because SP water pumps had the higher maximum discharge flow rate.
D. the collection method was nonrandom because only 10 water pumps from each manufacturer were selected.
Answers
Answer:
