What is the volume of this cylinder? 40yd 11yd
Use ≈ 3.14 and round your answer to the nearest hundredth.
Volume of the cylinder is 15197.60(to the nearest hundredth).
What is cylinder?
In mathematics, Cylinder is the basic 3d shapes, which has two parallel circular bases at a distance. The two circular bases are joined by a curved surface, at a fixed distance from the center which is called height of the cylinder.
Given that the radius of the cylinder is 11yd.
and the height of the cylinder is 40yd.
Formula for the volume of cylinder is π × r² × h where π=3.14, r= radius and h= height.
Putting the values we get,
Volume of the cylinder is = 3.14 × (11)² × 40 cubic yd.
= 15197.6
Hence, Volume of the cylinder is 15197.60(to the nearest hundredth).

Find the value of a $3,000 certificate in 2 years, if the interest rate is 10% compounded annually.
Answer:
600$
Step-by-step explanation:
3000×2×.10=600
the 10 percent needs to be changed to .10
The value of a \(\$3,000\) certificate in \(2\) years, if the interest rate is \(10\%\) compounded annually will be \(\$3630\).
What is compound interest?Compound interest is the addition of interest to the principal of a loan plus interest.
Amount\(= Principal(1+\frac{Rate}{100} )^{Time}\)
We have,
Principal \(=\$3,000\)
Rate \(= 10 \%\)
Time \(=2\) years
So, using above mentioned formula;
Amount\(= Principal(1+\frac{Rate}{100} )^{Time}\)
\(= 3000(1+\frac{10}{100} )^{2}\)
\(=3000 \ * (\frac{11}{10}) ^{2}\)
\(=\$3630\)
So, the amount after two year will be \(\$3630\) , which we find out using above mentioned formula.
Hence, we can say that the value of a \(\$3,000\) certificate in \(2\) years, if the interest rate is \(10\%\) compounded annually will be \(\$3630\).

Artificial grass sells for $10.98 per square yard final cost to buy and install 69.2 square yards if the seller charges $5.15 per square yard for labor round to the nearest cent
Answer:
$1,116.19.
Step-by-step explanation:
Given that artificial grass sells for $ 10.98 per square yard, to determine the final cost to buy and install 69.2 square yards if the seller charges $ 5.15 per square yard for labor, round to the nearest cent, the following calculation must be performed:
69.2 x (10.98 + 5.15) = X
69.2 x 16.13 = X
1,116,196 = X
Thus, the cost to purchase and install 69.2 square yards of artificial grass is $ 1,116.19.

Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,

Step-by-step explanation:
The equation of parabola is,
y = - 1/2x²
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
We have to given that;
In a parabola,
Vertex = (0, 0)
Since, We know that;
Standard form of equation of parabola is,
y = a (x - h)² + k
Where, (h, k) = (0, 0) = vertex
Hence, We get;
y = a (x - 0)² + 0
y = ax²
Here, A point on parabola is, (2, - 2)

A car with 12 gallons of gasoline drives 312 miles until the tank is empty.
Write a linear equation that describes the amount of gas left in the car, y, after driving x miles.
The linear equation is ________________. (Type your answer in slope-intercept form. Use integers or simplified fractions for any numbers in the expression.) *
Answer:
The linear equation is 312 - (312/12) X = Y.
Step-by-step explanation:
Given that a car with 12 gallons of gasoline drives 312 miles until the tank is empty, to determine a linear equation that describes the amount of gas left in the car, Y, after driving X miles, the following calculation must be performed:
312 - (312/12) X = Y
312 - 26X = Y
So, for example, if you were driving 4 miles, the equation would work as follows:
312 - 26 x 4 = Y
312 - 104 = Y
208 = Y

A, what was the total amount latoya ended up paying for the machinery. (including down payment and monthly payments)
B. How much interest did latoya pay on the loan
The total amount that Latoya ended up paying for the machinery, was $ 13, 080 .96
The amount of interest that Latoya paid was $ 980.96
How to find the total amount paid ?The total amount paid by Latoya for the machinery can be found as :
= Down payment of the machinery + ( Monthly payments x Number of months per year x Number of years )
= 1, 800 + ( 313. 36 x 12 x 3 )
= $ 13, 080 .96
The total interest paid on the loan was :
= ( Monthly payments x Number of months per year x Number of years ) - Worth of the machine - down payment
= ( 313. 36 x 12 x 3 ) - 12, 100 - 1, 800

a) Sketcheachsandbox.Includeitsdimensions.
b) Compare the designs. For each design, calculate the area

it will hold.
c) Whichsandboxshouldbebuilt?Justifyyouranswer.
The volume of the first and second designs are 2.7 m³ and 2.64 m³ so, the second design will hold more sand.
What is volume?
The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.
Given:
One design is 3 m by 3 m by 30 cm,
A second design is 3.25 m by 3.25 m by 25 cm,
Calculate the volume for the first design as shown below,
Volume of first design = 3 × 3 × 30/ 100 (1 m = 100 cm),
The volume of the first design = 270 / 100
The volume of the first design = 2.7 m³
Calculate the volume of the second design as shown below,
The volume of the second design = 3.25 × 3.25 × 25 / 100
The volume of the second design = 264.06 / 100
The volume of the second design = 2.64 m³
The difference in the volume of both designs = The volume of the first design - The volume of the second design
The difference in the volume of both designs = 2.7 - 2.64
The difference in the volume of both designs =0.06 m³
Thus, the first design will hold more volume of sand.

A music service chargers a $2.99 monthly membership fee plus $0.05 for each song purchased. If Naomi charges for the month was $10.89 how much songs did she purchase
Answer:
158
Step-by-step explanation:
10.89-2.99 = 7.90
.5/7.90=158
Answer:
158 songs
Step-by-step explanation:
Monthly membership = 2.99
Each song cost = .05
Total Amount spent after 1 month = 10.89
S = Songs purchased
=> 2.99 + .05S = 10.89
=> 2.99 - 2.99 + .05S = 10.89 - 2.99
=> .05S = 7.9
=> .05S / .05 = 7.9 / .05
=> S = 158
So, she purchased 158 songs that month.
