Find the volume of a right circular cone that has a height of 18.5 in and a base with a diameter of 17.5 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Step-by-step explanation:
volume of cone formula: V = 1/3 πr²h
r = 1/2 d
r = 1/2 (17.5)
r = 8.75 in
V = 1/3 (π8.75²)(18.5)
V = 1483.26 in²

In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer
than Noah, and Noah scores three times as many points as Mai. If Mai
scores 5 points, how many

The coefficient is 6
Step-by-step explanation:
Solve the following system of equations using elimination
Answer:
Well elimination is basically multiplying a number to make it possible for it to cancel out
We can multiply the first equation by 2
2(x+2y=-1)
This would be
2x+4y=-2
Its still the same thing but just with non simplified numbers
We can now do any method really to solve
I will just do the subtraction method
2x+4y=-2
-2x+y=4
Solve
2x-2x=0
4y-y= 3y
-2-4= -6
3y= -6
Now solve
y=-2
To find x subsitute in “y” and find ”x”.
x+2*-2=-1
x-4=-1
x=3
y= -2
x= 3
For her birthday, Gale received $200. She would like to spend all or some of the money to take
guitar lessons. After an initial $50 fee to cover rental equipment, each guitar lesson will cost $25.
Write an inequality to determine how many lessons Gale could take using her birthday money.
Highlight your inequality in green. Then, solve the inequality.
Answer:
The inequality that can be used to determine the number of guitar lessons Gale could take using her birthday money is:
[tex]25x + 50 \leqslant 200[/tex]
The solution to the inequality is:
[tex]x \leqslant 6[/tex]
She can take at most, 6 guitar lessons
Step-by-step explanation:
Total amount Gale received is $200
For rental equipment, she paid $50
Each guitar lesson will cost $25
Let x represent the number of lessons she could take, then the total amount she will spend must bot exceed $200
The guitar lesson will cost a total of 25x
So, her total spending will be:
[tex]25x + 50[/tex]
This must be at most $200
[tex]25x + 50 \leqslant 20[/tex]
Solving the above inequality:
[tex]25x \leqslant 200 - 50 = 150[/tex]
[tex]x \leqslant \frac{150}{25} = 6[/tex]

Bart designed a logo using circles of different sizes. The diameters of three of the circles are
shown. Which measurement is closest to the area of the largest circle in square centimeters?
A 20.7 cm2
B 136.8 cm2
C 34.2 cm2
D 65.1 cm
Answer:
B 136.8 cm²
Step-by-step explanation:
Add the diameters of the three smaller circles to find the diameter of the largest circle.
D = 3 cm + 2.5 cm + 1.1 cm = 6.6 cm
area = πr²
area = 3.14 × (6.6 cm)²
area = 136.8 cm²

what is the are of this?
Answer:
Ok first of all you start out splitting the shape into seperate rectangles, in this case 2. take those 2 rectangles and find the area of them. Say we start from the smaller rectangle. 2 x 4 = 8 so the area of the smaller rectangle is 8. Keep that in mind. Next we have to multiply 10 x 5 because that is the labeled number of meters and that equals 50. So add 50 + 8 = 58
Step-by-step explanation:
Your answer is 58 meters
Really hope i helped and have a wonderful day! :)
Answer:
58 m³
Step-by-step explanation:
To find the area of irregular shapes like this, it is easy to split the shape into 2 individual shapes, find the area of both, then add the areas to find the total.
Now, we'll split it into 2 rectangles with areas of:
2 x 4
10 x 5
To find area, you multiply the length of one side by the other. The first rectangle's area is (2 x 4) and the other rectangle's area is (10 x 5).
10 x 5 = 50
2 x 4 = 8
50 + 8 = 58
The area of the figure is 58 m³.

Point S is on line segment RT. Given ST=3 and RT=20, determine the length RS.
Answer:
RS = 17
Step-by-step explanation:
Given S lies on RT , then
RS + ST = RT , that is
RS + 3 = 20 ( subtract 3 from both sides )
RS = 17
