Answer:
Volume of a cylinder = 1,100cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
Given
π = 22/7
r = 5cm
h = 14cm
Substitute the given information in the problem.
Volume of a cylinder = 22/7 × (5cm)² × 14cm
Volume of a cylinder = 22/7 × 25cm² × 14cm
Volume of a cylinder = 1,100cm³

Mr. Chan’s lawn grows 2 1/8 inches every 2 week. He mows his lawn every 2 weeks and cuts off the top 1 3/4 inches of lawn. If Mr. Chan’s lawn was 4 inches tall at the beginning of the season, how many inches tall, in decimal form, is Mr. Chan’s lawn after 8 weeks.
Answer:
5.5 in
Step-by-step explanation:
First we will calculate the total lawn grown after 8 weeks.
Grow Rate = [tex]2\frac{1}{8} in/2 weeks[/tex]
Total lawn grown after 8 weeks = [tex]2\frac{1}{8} *4\\=8.5 in[/tex]
Next we will calculate the total lawn mown after 8 weeks.
Mowing Rate = [tex]1\frac{3}{4} in/2weeks[/tex]
Total lawn mown after 8 weeks = [tex]1\frac{3}{4} *4\\=7 in[/tex]
Lawn Height after 8 weeks = Initial Lawn Height + Total lawn grown - Total lawn mown
= 4 in + 8.5 in - 7 in
= 5.5 in

The volume of the square prism shown is 1568 cubic meters
Volume of square prismThe formula for calculating the volume of square prism is expressed as;
V = Base area * height/3
Determine the base are
B = 14 * 14
B = 196 square meters
Determine the height
h = √25² - 7²
h = √625 - 49
h = 24m
Substitute
Volume = 196. * 24/3
Volume = 196 * 8

Answer: 76.5 meters
Step-by-step explanation:
To find the side lengths you use trig ratios for 30,60,90 triangles. The ratio is n (attached to the opposite side of the 30-degree angle, or the smallest leg), n[tex]\sqrt{3}[/tex] (attached to the opposite side of the 60-degree angle, or the longest leg), 2n (attached to the hypotenuse). Using the inner triangle you can use 2n=28 to find the side opposite the 30-degree angle, 14. Then you plug 14 into every n and add the sides. the full answer is 76.4974226 but this problem said to round making your final answer 76.5 meters. always remember to give proper units.

Solve for x 3x – 2(3x – 2) = 2(4 – x) + 3
Answer:
x = -7Step-by-step explanation:
First, lets open up the parentheses.
3x - 6x + 4 = 8 - 2x + 3
Combine like terms.
-3x + 4 = 11 - 2x
Add 2x to both sides
-x + 4 = 11
Subtract 4 from both sides
-x + 4 -4 = 11 -4
Simplify
-x = 7
Divide both sides by -1
x = -7
Hope this helps! (:
Answer:
x = -7
Step-by-step explanation:
3x – 2(3x – 2) = 2(4 – x) + 3
The first step is to distribute when solving for x
3x – 6x +4 = 8 – 2x + 3
Then combine like terms
-3x+4=-2x+11
Add 3x to each side
-3x+3x+4=-2x+3x+11
4 = x+11
Subtract 11 from each side
4-11 = x+11-11
-7 = x

Calculate the area of this triangle.
[tex] [/tex]
Answer: 30
Step-by-step explanation: Formula for Area of a triangle = 1/2 Base * Height. 12*5 = 60; 60/2 = 30.
Answer:
30 cm squared
Step-by-step explanation:
This is a right angle triangle. That means that the base and height will just be the perpendicular sides of the triangle.
Our base in this case is 12 and our height is 5.
Area of a Triangle = 1/2(base)(height)
=1/2(12)(5)
=1/2(60)
=30
So, the area of this triangle is 30 cm squared.

Answer:
The distance between the poles is approximately 15.2 m.
Step-by-step explanation:
GivenTwo poles of 25 m and 30 m height,Distance between tops of the poles is 16 m.To findThe distance between the polesSolutionThe distance between the poles is the segment d which connects the top of the shorter pole with the point at 5 m from the top of the longer pole, which is the difference of lengths of poles.
The three points form a right triangle, with hypotenuse of 16 m, and legs 5 m and d.

In 11.76 months, the value of the population will be 15000.
We have given that,
At the end of January 2003, the population of my town was 11,212.
the population is increased by 322 every month
So at the end of the second-month population will be 11534.
suppose x represents the year and y represent the population
The population increased by 322 every month
Therefore the value of m =322
[tex](x_1,y_1)=(0,11212)[/tex]
We have m=332
[tex](x_2,y_2)=(x_2,15000)[/tex]
