Answer:
The volume of the cylinder is 1,728·π cm³
Step-by-step explanation:
The given parameters are;
The radius of the cylinder, r = 12 cm
The location of the hemisphere = Inside the cylinder
The size relationship between the hemisphere and the cone = Snuggly fit
Therefore, we have;
The radius of the hemisphere = The radius of the cylinder = 12 cm
The height of the cylinder, h = The radius of the hemisphere = 12 cm
The volume of the cylinder, V = π·r²·h
Where;
h = 12 cm
r = 12 cm
Therefore;
V = π·r²·h = π × (12 cm)² × 12 cm = (12 cm)³·π = 1,728·π cm³
The volume of the cylinder, V, in terms of pi (π) is, V = 1,728·π cm³.
Which type of triangle will always have at least 1-fold reflectional symmetry?
right triangle
obtuse triangle
acute triangle
isosceles triangle
Answer:
Isosceles triangle I think
Step-by-step explanation:
The triangle that will always have at least 1-fold reflectional symmetry is the isosceles triangle. That is option D.
What is reflectional symmetry?Reflectional symmetry is found in geometric shapes that can be folded over onto itself along a line.
The isosceles triangle has only one line of symmetry or 1-fold reflectional symmetry.
Therefore, the triangle that will always have at least 1-fold reflectional symmetry is the isosceles triangle.

Melanie invested $3,800 in an account paying an interest rate of 2 % compounded
quarterly. Sebastian invested $3,800 in an account paying an interest rate of 2%
compounded monthly. After 6 years, how much more money would Sebastian have in
his account than Melanie, to the nearest dollar?
Answer:
.85
Step-by-step explanation:
Compound interest formula
[tex]PV(1+\frac{i}{n})^{nt}[/tex]
Melanie:

How do I round 2726.821341 to the nearest cent
Answer:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.

Rounding calculator to round numbers up or down to any decimal place. Choose ones to round a number to the nearest dollar. Choose hundredths to round an amount to the nearest cent.
Rounding Numbers
Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:
Rounding to the nearest hundred is 800
Rounding to the nearest ten is 840
Rounding to the nearest one is 838
Rounding to the nearest tenth is 838.3
Rounding to the nearest hundredth is 838.27
Basic Rules of Rounding
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Round to the Nearest Hundred: 3250
Identify the hundreds digit: the 2 in 3250
Identify the next smallest place value: the 5 in 3250
Is that digit greater than or equal to five? Yes, so round up.
Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.
3250 rounded to the nearest hundred is 3300
Round to the Nearest Ten: 323.5
Identify the tens digit: the 2 in 323.5
Identify the next smallest place value: the 3 in 323.5
Is that digit greater than or equal to five? No, so round down.
The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.
323.5 rounded to the nearest ten is 320
Round to the Nearest Ten: 499
Identify the tens digit: the first 9 in 499
Identify the next smallest place value: the second 9 in 499
Is that digit greater than or equal to five? Yes, so round up.
The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.
499 rounded to the nearest ten is 500
Round to the Nearest Tenth: 0.74
Identify the tenths digit: 7 in 0.74
Identify the next smallest place value: the 4 in 0.74
Is that digit greater than or equal to five? No, so round down.
The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.
0.74 rounded to the nearest tenth is 0.7
Round to the Nearest Hundredth: 3.141
Identify the hundredths digit: the 4 in 3.141
Identify the next smallest place value: the second 1 in 3.141
Is that digit greater than or equal to five? No, so round down.
The hundredths digit stays the same at 4. Drop the digits to the right of 4.
3.141 rounded to the nearest hundredth is 3.14

HELPPPPPP MEEEEE
Answer:
this is a confusing one
Step-by-step explanation:
Substitute each variable to determine whether the inequality statement is true or false 16>f if f=17
Answer: The statement is false.
Step-by-step explanation:
We have the statement:
(16 > f) if f = 17
In this case:
f = 17 is the hypothesis.
16 > f is the conclusion.
Then assuming that the hypothesis is true, we need to check if the conclusion is also true.
Then:
16 > f means "16 is larger than f"
Now let's assume that the hypothesis is true, then f = 17, and we can replace this in the inequality above, now we get:
16 > 17
This says "16 is larger than 17"
This is clearly false, then when the hypothesis is true, the conclusion is false.
This means that the statement:
" 16>f if f=17 "
is false.

Solve the equat: n. -2x+3)+5x=-39
Answer:
x=-11
Step-by-step explanation:
-2(x+3)+5x: 3x-6

=-2x-6+5x
-2x-6+5x: 3x-6
3x-6=-39
Add 6 to both sides
3x-6+6=-39+6
Simplify
3x=-33

6.
2x + 5y = 14
4x + 2 y = -4
Answer:
x=−3 and y=4
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(2x+5y=14)
1(4x+2y=−4)
Becomes:
−4x−10y=−28
4x+2y=−4
Add these equations to eliminate x:
−8y=−32
Then solve−8y=−32for y:
−8y=−32
−8y
−8
=
−32
−8
(Divide both sides by -8)
y=4
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2x+5y=14
Substitute4foryin2x+5y=14:
2x+(5)(4)=14
2x+20=14(Simplify both sides of the equation)
2x+20+−20=14+−20(Add -20 to both sides)
2x=−6
2x
2
=
−6
2
(Divide both sides by 2)
