Answer:
6583.5 cm³
Step-by-step explanation:
[tex]\boxed{volume \: of \: hemisphere = \frac{2}{3}\pi {r}^{3} }[/tex]
[tex]\boxed{volume \: of \: cylinder = \pi {r}^{2} h}[/tex]
Thus, volume of half cylinder= ½πr²h
Since both has a radius of 10.5cm, substitute r= 10.5 into both formulas. The value of h is 24 since it is given that the height of the half cylinder is 24cm.
Volume of composite solid
[tex] = \frac{2}{3}( \frac{22}{7})(10.5^{3} ) + \frac{1}{2} ( \frac{22}{7} )( {10.5}^{2} )(24) \\ = 2425.5 + 4158 \\ = 6583.5 \: cm^{3} [/tex]

Which of these lengths is the greatest?
8 feet or 100 inches
Answers
Answer:
100 inches is greater..
Step-by-step explanation:
1 foot = 12 inches 8 feet = 96 inches (100 inches is longer than 8 feet ). 100 inches is greater than 8 feet which equals 96 inches.
They both round up to 8 feet, so they're equal.
If you're asking for an exact answer though, it'd be 100 inches since it's 4 inches above 8 feet.

The problem has been started for you. 8 StartLongDivisionSymbol 468 EndLongDivisionSymbol minus 40 = 68. 68 minus 64 to get a remainder of 4 and a quotient of 58. What is the quotient?
Answers
Answer:
Quotient = 58
Step-by-step explanation:
We are to find the quotient of the expression using long division method. This is as shown in the attachment.
The expression is expressed as;
468/8
This can be expressed as ;
468/8 = 58 + 4/8
Note that according polynomials are expressed as;
P(x) = Q(x) + R(x)/D(x)
Where;
Q(x) is the quotient
R(x) is the remainder
D(x) is the divisor
Comparing with the expression 58 4/8, you will see that Q(x) is 58.
Hence the quotient when 8 is divided by 468 is 58.

If T is the circumcenter of MNP, find the indicated measure:
Find MN
Answers
Answer:
MN = 55
Step-by-step explanation:
Since T is the circumcenter of ∆MNP, it follows that the perpendicular bisector of side MN divides MN into two equal parts.
Therefore:
MR = RN
MR = 10x -13
RN = 17x - 41
Thus:
10x - 13 = 17x - 41
Collect like terms
10x - 17x = 13 - 41
-7x = -28
Divide both sides by -7
x = 4
MR + RN = MN
(10x - 13) + (17x - 41) = MN
Plug in the value of x
(10(4) - 13) + (17(4) - 41) = MN
(40 - 13) + (68 - 41) = MN
27 + 27 = MN
54 = MN

Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9A a few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
Answers
Given :
Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9 sign a few weeks from now.
Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
To Find :
Least possible number of times that Miranda has been to the store.
Solution :
It is common to see that :
7 dollar/visit ×9 visits = $63
9 dollar/visit ×7 visits = $63
Therefore, minimum number of times Miranda has been to the store is 9.
Hence, this is the required solution.
