A cone - shaped building has a height of 6 meters and a base with a diameter of 10 meters. The building will be filled with road salt that costs $25 per cubic meter. How much will it cost to fill the building with road salt? Use 3.14 for π Round to the nearest hundredth HELP ME ASAP!!!!
Answers
.. V = (1/3)*π*r^2*h
The radius (r) is half the diameter, so is 5 m. Fill in the numbers and do the arithmetic.
.. V = (1/3)*3.14*(5 m)^2*(6 m) = 157 m^3
The cost will be $25 for each of those cubic meters, so is
$25*157 = $3925.00.
V= (1/3) pi r^2 h
r = d/2 = 10/2 = 5
h = 6
pi = 3.14
V = (1/3) * 3.14 * 5^2 * 6
V = (1/3) * 471
V = 157 cubic meters.
1 cubic foot cost $25
157 cubic feet cost x Cross multiply.
x = 25 * 157
x = 3925 dollars.

justin can type w words per minute. melvin can type 4 times as many words as justin. write an expression that represents the rate at which Melvin can type
Answers
w = Words per min that Melvin can type
w = m*4
Melvin's typing rate can be expressed as 4w words per minute by multiplying Justin's rate by 4.
To determine how many words Melvin can type per minute, we need to use Justin's typing rate as a reference.
Since Justin can type w words per minute, and Melvin can type 4 times as many words as Justin, we multiply Justin's rate by 4.The expression for Melvin's typing rate is 4w words per minute.For example, if Justin types 50 words per minute (w = 50), then Melvin would type 200 words per minute (4 * 50 = 200).

Angle JKL and MKQ are complementary angles.
The measure if angle JKL is twice the measure of angke MKQ.
Write one equation to find x, the measure if angle MKQ, and then solve for x
Enter your equation and your solution in the space provided
Answers
The equation of the complementary angles can be represented as 2x + x = 90° and the measure of ∠MKQ is 30 degrees.
What are complementary angles?
Complementary angles are angles that sum up to 90 degrees. The angles complement each other.
Therefore,
∠JKL + ∠MKQ = 90°
let
∠MKQ = x
Hence,
∠JKL = 2x
Therefore,
2x + x = 90°
3x = 90
divide both sides by 3
3x / 3 = 90 / 3
x = 30

Answers
Final answer:
The area of a triangle with a base of 166 mm and height of 930.0 mm is found by converting the measurements to meters and using the formula A = 1/2 × base × height. It calculates out to be 0.07719 m² and should be reported as 0.0772 m² to match the least number of significant figures provided in the measurements.
Explanation:
To calculate the area of a triangle, you use the formula A = 1/2 × base × height. Given the base is 166 mm and the height is 930.0 mm, first, you need to convert the measurements to meters by dividing them by 1000 (since there are 1000 millimeters in a meter), which gives us 0.166 m for the base and 0.930 m for the height. Then you plug these values into the formula:
A = 1/2 × (0.166 m) × (0.930 m)
So the area of the triangle is:
A = 1/2 × 0.15438 m²
A = 0.07719 m²
This result should be reported with the proper number of significant figures. Given that the base was provided to three significant figures and the height to four, the area should also be reported to three significant figures since the number of significant figures in the answer is determined by the measurement with the fewest significant figures. Therefore:
Area = 0.0772 m²

Which number is an irrational number?

B: 0.1257486
C: 0.12121212
D: 0.111111
Answers
So 0.1257486 is the answer.
Final answer:
The irrational number in the given options is C: 0.12121212, as it repeats the sequence '12' infinitely without any pattern.
Explanation:
An irrational number is a number that cannot be expressed as a simple fraction (i.e. a ratio of two integers) and has an infinite number of non-repeating decimal places. Out of the given options, the number C: 0.12121212 is an irrational number because it repeats the sequence '12' infinitely without any pattern. The other options, A: 0.12, B: 0.1257486, and D: 0.111111, can all be expressed as fractions and have either a finite decimal representation or a repeating decimal pattern.
Jordan and Roman travel the same route to work. Jordan leaves work one morning and drives at a rate,r, of 56 mph. Roman leaves the house soon after, when Jordan has already traveled 2 mo. Roman drives at a rate of 60 mph. How long after Jordan leaves home well Roman catch up to her? How many miles into the commute Will this occur
Answers
Explanation:
1) Data:
Jordan's speed: r1 = 56 mi / h
Roman's speed: r2 = 60 mi / h
Jordan's initial position: 2 miles
Roman's initial position: 0 miles
2) Formula:
Both motions are at constant speed, so rate = distance / time
Position = Initial position + distance run = initial position + rate * time
3) Solution:
Jordan's position, x1 = 2 mi + 56 mi / h * t
Roman's position, x2 = 0 mi + 60 mi/h * t = 60 mi / h
They start driving at the same time, so their times are equal.
When Roman catch up Jordan their position are equal => x1 = x2
=> 2 + 56t = 60 t
=> 60t - 56t = 2
=> 4t = 2
=> t = 2/4 = 0.5 hours
Now you can calculate the position of both in the commute:
From Jordan's rate: x1 = 2 mi + 56 mi /h * 0.5 h = 2mi + 28mi = 30 mi
From Roman's rate: x2 = 60 mi/h * 0.5 h = 30 mi
Answer: Roman will catch up Jordan after 0.5 h, and they will be 30 miles into the conmute.
A 1 1/2-pound piece of turkey costs $7.98. A 6-ounce package of the same sliced turkey costs $2.49. What is the difference in price per 3-ounce serving?
Answers
The difference in price per 3-ounce serving package is $0.2475.
Price Per Serving CalculationFirst, we need to determine the cost per 3-ounce serving for each type of turkey packaging. Since there are 16 ounces in 1 pound, a 1 1/2-pound piece of turkey is equivalent to 24 ounces.
Cost per ounce for the 1 1/2-pound turkey: $7.98 \/ 24 ounces = $0.3325 per ounce.
Cost per 3-ounce serving for the 1 1/2-pound turkey: $0.3325 x 3 = $0.9975.
The 6-ounce package costs $2.49, so:
Cost per ounce for the 6-ounce package: $2.49 \/ 6 ounces = $0.415 per ounce.
Cost per 3-ounce serving for the 6-ounce package: $0.415 x 3 = $1.245.
The difference in price per 3-ounce serving between the two types of turkey is: $1.245 - $0.9975 = $0.2475.
