There is 3 4 of an apple pie left from dinner. Tomorrow, Victor plans to eat 1 4 of the pie that was left. Enter how much of the whole pie he will eat tomorrow.
Answer:
3/16
Step-by-step explanation:
Let the size of the whole apple be T
Given that 3/4 of the apple is left, it means the size left
= 3T/4
Since Victor plans to eat 1/4 of the pie that was left, this amounts to
1/4 * 3T/4
= 3T/16
This means that Victor will eat 3/16 of the whole pie tomorrow

you pretty much have too find the other letter that finishes the shape.
so #21 it would be P because it is for the bottom shape/base shape. and you already have M,N and O so the last one you need too finish the shape is P. and the same concept for the other awnsers
Hope this isn't too complicated and helps u out!

These numbers are common multiples of ________.
6, 12, 18, 36
A) 2 and 4
B) 2 and 3
C) 3 and 4
D) 4 and 6
From this list, we can see that all the numbers are multiples of 2 and 3. So, the correct answer is option B) 2 and 3.
What are common multiples?
Common multiples are multiples that two or more numbers have in common. In other words, common multiples are numbers that are multiples of two or more given numbers.
To find the common multiples of 6, 12, 18, and 36, we can start by finding the prime factorization of each number:
6 = 2 x 3
12 = [tex]2^2[/tex] x 3
18 = 2 x [tex]3^2[/tex]
36 = [tex]2^2[/tex] x [tex]3^2[/tex]
To find the common multiples, we need to list the multiples of the largest number, which is 36, and check which ones are also multiples of the other numbers:
Multiples of 36: 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, 396, ...
Therefore, From this list, we can see that all the numbers are multiples of 2 and 3. So, the correct answer is option B) 2 and 3.

Please help me I don't knoe
Answer:
x = sqrt(147)
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
x^2 = 147
Take the square root of each side
sqrt(x^2) = sqrt(147)
x = sqrt(147)
Answer:
[tex]7\sqrt{3}[/tex] or 12.12
Step-by-step explanation:
The pythagorean theorem states that a^2 + b^2 = c^2, with a and b representing the legs and c representing the hypotenuse.
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = [tex]7\sqrt{3}[/tex] or 12.12

What is the slope of a vertical line?
What is the slope of a horizontal line?
Answer:
The slope of a vertical line is undefined. The slope of a horizontal line is 0
Step-by-step explanation:
Slope is rise/run
and the rise of a horizontal line is zero since it neither increases nor decreases; therefore, the slope is zero. while a vertical line has undefined slope since it does not run horizontally because division by zero is an undefined operation.

Find the volume of this cylinder
Answer:
volume of cylinder= pie × radius square× height
= 22/7×4×20
=1760/7
=251.42cm
Answer:
using 3 for pi it's V = 960cm^3
Step-by-step explanation:
R is the radius, which as stated, is half the diameter.
r = 8cm / 2 = 4cm
H is the height, which is shown to be 20cm
h = 20cm
V = pi*r^2*h
V = pi*(4cm)^2*20cm
substituting 3 for pi as requested.
V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3

If a ball has a rebound ratio of 0, what does that mean?
Answer: The test is conducted with an electromagnetic or vacuum release mechanism which releases a soccer ball from a height of 2 meters. From that the height of the rebound is measured by recording the sound of the first and second bounce. The time between the first and second bounce is measured. Also During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. ... It reaches way higher than from the height it was released.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes
Answer: 10,098 votes
Step-by-step explanation:
The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.
To find the total votes, add the ratios:
= 7 + 4
= 11
4/11 are the no votes out of the total. Assuming the total is x, the formula is:
4/11x = 3,672
x = 3,672 / 4/11
x = 10,098 votes
