Answer:
108π cm^3/min
Step-by-step explanation:
At a time of t min, let the height be h cm
The volume of a cylinder;
V = π r^2 h
= 36π h
differentiating both sides with respect to t;
dV/dt = 36π dh/dt
but dh/dt = 3 cm/min
dV/dt = 36π(3) = 108π cm^3/min

1.What is the length of the altitude of an equilateral triangle with side lengths of 34 inches?
2. The bottom of a ladder must be placed 10 feet from a wall and reach a height of 16 feet. How long is the ladder?
I need help pls
Answer:
Step-by-step explanation:
Remark
Question One
It's equilateral. All three sides are equal. The base is 34 as well. So two right angles can be formed on the base by dropping the altitude from the top vertex.
Givens
altitude = h
a = 34/2 = 17
hypotenuse = 34
Formula
a^2 + h^2 = c^2
Solution
17^2 + h^2 = 34^2
289 + h^2 = 1156
h^2 +289 =1156
h^2 = 1156 - 289
h^2 = 867
sqrt(h^2) = sqrt(867)
h = 29.444
==============
Question Two
Givens
b = 10 feet
c = ?
height = h = 16
Formula
c^2 = b^2 + h^2
Solution
c^2 = 10^2 + 16^2
c^2 = 100 + 256
c^2 = 356
sqrt(c^2) = sqrt(356)
c = 18.87
A tennis shoes regularly sells for $20.00. The store advertises a 15% discount. What is the sale price of the necklace in dollars?
Answer:
Shoes with discount = $17
Necklace = Price * 0.85
Step-by-step explanation:
-If the tennis shoes store sells other things than shoes-
Shoes = $20.00
Discount = 15%
*Price expressed as a percentage*
Price without discount = 100%
Price after discount = 100% - 15%
Price after discount = 85%
*Normal price*
Price without discount = 20
Price after discount = 20 * 0.85
Price after discount = 17

What is the hexadecimal conversion of the decimal number 224?
Answer:
This is a little confusing to me this question but I think its "E0"
Step-by-step explanation:
a) Divide 224 by 16 and then separate what is on the left and right side of the decimal point.
b) Multiply the right side of the decimal point by 16 (and convert to hex if neccessary) and keep that number to the side.
c) Divide the left side of the decimal point by 16 and separate what is on the left and right side of the decimal point.
d) Repeat step b and c above until the value on the left side is 0.
e) Then simply enter the numbers you got in step b in reverse order to get the answer.
Following the instructions above, your math should look like this:
224 / 16 = 14
0 x 16 = 0
14 / 16 = 0.875
0.875 x 16 = E
Thus, 224 decimal converted to hex is as follows:
E0

Triangle ABC has 3 medians drawn creating centroid D. If a centroid creates a 2:1 ratio and one median is 24 inches, what is the larger piece?
PLS HELP ASAP! WILL MARK BRAINLEST!! THX :)
Answer: The larger piece is 16 inches
Step-by-step explanation: Median of a triangle is a line segment uniting a vertex and the midpoint of the opposite side. A triangle has 3 medians and the point where these 3 intersect is called centroid.
The ratio of one median is 2:1, which means the line segment is divides by the centroid into two parts, one the double of the other. So:
2x + x = 24
3x = 24
x = 8
Then, the larger piece is
2x = 2(8) = 16
The larger part of the median measuring 24 inches is 16 inches

Write 6.384 correct to 1 decimal place ?
Answer:
Write 6.384 correct to 1 decimal place ?=6
Answer:
6.4
Step-by-step explanation:
Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth. The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.
In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.
The number rounded to one decimal place is 6.4.

if You aren’t sure Its right then multiply 25 and 28 and you get 700
An electrician has a piece of wire that is 4 and 3/8 cm long. She divides the wire into pieces that are 1 and 2/3 cm long. how many pieces does she have? (Type out your work)
Answer:
She has approximately 3 pieces ( 2.625)
Step-by-step explanation:
To get the number of pieces, we need to divide the length of the wire by the individual length of the pieces.
To get the division done, it would be easier to convert what we have into improper fractions
For the piece of wire, the length which is 4 and 3/8 centimeters long will be 35/8 centimeters
while;
the individual length of each of the piece which is 1 and 2/3 centimeters long will be 5/3 centimeters
The number of pieces is thus 35/8 divided by 5/3 = 35/8 * 3/5 = 21/8 = 2.625 which is approximately 3 pieces
Hope this helped

Logan ate g out of 16 gumdrops. Write an expression that shows how many gumdrops Logan has left.
Answer:
16-g=x
Step-by-step explanation:
You know you need to subtract because it says ate out of. Next you don't know how many gumdrops Logan ate so they gave a the variable g. Since you don't know how many gumdrops he ate you don't know how many are left. You need another variable to represent how many gumdrops are left.
determine the axis of
symmetry for y=x²+2
Answer:
x=0
Step-by-step explanation:
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b/2a
in our case
y=x^2+2
a=1 b=0 c=2
so x=-b/2a=-0/2*1=0
x=0 is axis of symmetry

5. A life insurance policy costs $16.00 for every $1,000.00 of insurance. At
this rate, what is the total policy cost for $50,000.00 of insurance.
Answer:
800.00
Step-by-step explanation:
so you give me a hint that was for every 16.00 it was 1000.00
i did 16x50=800
i got 50 from 50 in 50000 and the 16 from 16.00 so then i times 16 from 50 which is 800
