Volume of a Cone
15cm
V= 7r2h
3
14cm
V
V~ [?]cm3
Answer:
171 cm³
Step-by-step explanation:
The object is composed of a cone and a cylinder.
Volume of the object = volume of cone + volume of cylinder
✔️Volume of Cone = ⅓πr²h
r = ½ of 6 = 3 cm
π = 3
h = 5 cm
Volume of cone = ⅓×3×3²×5
Volume of cone = 45 cm³
✔️Volume of cylinder = πr²h
π = 3
r = ½ of 6 = 3 cm
h = 14 cm
Volume of cylinder = 3×3×14
Volume of cylinder = 126 cm³
✔️Volume of the object = 45 + 126 = 171 cm³

The side lengths of A'A and B'B are 18 and 9 respectively.
What are similar triangles?When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.
Given that, segment A'B' is parallel to segment AB.
Let A'A =x and B'B = y.
Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.
As per the property of similar triangles, it follows:
12/8 = (12 + x)/20
12 + x = (12/8)20
x = 18
And,
6/8 = (6+y)/20
6 + y = (6/8)20
y = 9
Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

Help on number two and plz
Answer:
The awnser would be 9 because its under the sum of 10
Answer:
9 (see below)
Step-by-step explanation:
So, for a triangle, if you add any two sides, it will always be greater than the third side.
So if a triangle has sides of 1, 1, and 1:
1 + 1 > 1
1 + 1 > 1
1 + 1 > 1
So this is a triangle.
For a triangle with the sides of 3, 3, and 9:
3 + 9 > 3
9 + 3 > 3
3 + 3 > 9 (this one is not true)
So, these can't be the values of the sides of a triangle.
For your situation, you have a triangle with sides of 4, 6, and x.
We need to find out what x is, so:
4 + 6 > x
4 + x > 6
6 + x > 4
Isolate x to one side and simplify all the inequalities. You will get:
x < 10
x > 2
x > -2
So, -2 < x < 10.
If you plug in your answer choices, it will be 9.
You have $1,000 of birthday money in a savings account that earns 8% simple interest. If you have not spent any of it for 5 years, what is your TOTAL balance? (Balance = Principal + Interest)
Answer:
Your Balance Would Be $1400.
How I Found The Answer:
$1000 Is 100%
$1000 ÷ 100 = $10
$10 Is 1%
$10 × 8 = $80
$80 × 5 = $400
$1000 + $400 = $1400
Your Balance Would Be $1400.

When Groundhog Day is
on a weekday,
around15,000 people
attend the events in
Punxsutawney, PA. If two-
thirds take the shuttle bus
to the park for $5 and the
rest pay $25 for parking,
how much money does
the city earn?
====================================================
Work Shown:
2/3 of 15,000 = (2/3)*15000 = 10,000
This means 10,000 people take the shuttle bus to the park. If each person pays $5 to take the bus, then the city earns 5*10,000 = 50,000 dollar through this option.
The rest pay for parking, so 15,000-10,000 = 5,000 people pay for parking. At $25 each, this amounts to 25*5,000 = 125,000 dollars earned through this option.
Overall, the city earns a total of 50,000+125,000 = 175,000 dollars
Side note: this assumes that the remaining 5,000 people all take separate cars and no single car has more than one person. This is very unrealistic as there are likely to be families or carpools of some kind. So in reality, the answer shown above is an upper estimate of the total revenue.

3х + Зу = -x+5y ordered pair
Answer:
2x-y=0
x=1/2y
Step-by-step explanation:
Answer:
Your solution is (1/2, 1).
Step-by-step explanation:
3х + Зу = -x + 5y
First we want to look at each side of the equation separately.
3х + Зу ⇒ This expression is fully simplified because you cannot add different variables together.
-x + 5y ⇒ This expression is fully simplified because you cannot add different variables together.
3х + Зу = -x + 5y
Now, let's bring the like terms together.
[add x to both sides]
x + 3x + 3y = -x + x + 5y
4x + 3y = 5y
[subtract 3y from both sides]
4x + 3y - 3y = 5y - 3y
4x = 2y
We want to solve for one variable at a time, so let's isolate x.
[divide both sides by 4]
4x/4 = 2y/4
x = 1/2y
Now we have an expression for x. Plug this expression in to your original equation.
3х + Зу = -x + 5y
3(1/2y) + 3y = -(1/2y) + 5y
According to PEMDAS (parentheses/exponents | multiplication/division | addition/subtraction), we should multiply first.
3(1/2y) + 3y = -(1/2y) + 5y
3/2y + 3y = -1/2y + 5y
Now let's add on each side.
9/2y = 9/2
Now we need to isolate y by dividing both sides by 9/2 (or multiplying by its reciprocal 2/9 ← This is often easier to understand when written)
[tex]\frac{2}{9} (\frac{9}{2} y) = \frac{9}{2} (\frac{2}{9} )[/tex]
In this form, we can see that the fractions cancel each other out.
y = 1
Now that we have the value of y, plug it into our equation for x.
x = 1/2y
x = 1/2(1)
Multiply.
x = 1/2
Your solution is (1/2, 1).
You're almost done! Check your answer by plugging in both these values in to your original equation.
3х + Зу = -x + 5y
3(1/2) + 3(1) = -(1/2) + 5(1)
Multiply.
3(1/2) + 3(1) = -(1/2) + 5(1)
3/2 + 3 = -1/2 + 5
Add.
9/2 = 9/2
This equation is true, therefore your answer is correct!
Hope this helps!

Fifteen unit squares are arranged in a 5 by 3 rectangle as shown. What percent of the largest rectangle is shaded gray?
PLS PLS TELL WHY THE ANSWER IS TRUE!!
Answer:
40%
Step-by-step explanation:
There's a total of 15 squares.
So the percentage that is gray would be [tex]\frac{6-gray-squares}{15-total-squares}[/tex] which simplifies to [tex]\frac{2}{5}[/tex] in fraction form or 40%
What percent is represented by the shaded area?
Answer:
30%
Step-by-step explanation:
There are 6 shaded squares out of 20 squares. That is the same as 30 out of 100. 30/100=30%

discount amount=d%ofmp=5/100×0.25cp=0.0125cp
sp=mp-discount=1.25cp-0.0125cp=1.2375cp
