The cone and cylinder above have the same radius and height. The volume of the cylinder is 48 cm3. What is the volume of the cone?
A.
24 cm3
B.
16 cm3
C.
96 cm3
D.
144 cm3
Answer:
Option B (16 cm³)
Step-by-step explanation:
GIVEN :-
Both cone and cylinder have same radius and height.Volume of cylinder = 48 cm³TO FIND :-
Volume of coneFACTS TO KNOW BEFORE SOLVING :-
Volume of a cylinder having radius 'r' and height 'h' is [tex]\pi r^{2} h[/tex]Volume of a cone having radius 'r' and height 'h' is [tex]\frac{1}{3} \pi r^{2} h[/tex]Hence ,
Volume of cylinder = Thrice the volume of cone
[OR]
Volume of cone = One third of volume of cylinder
PROCEDURE :-
Volume of cone = [tex]\frac{1}{3} (Volume \: of \: cylinder) = \frac{48}{3} = 16cm^3[/tex]

We have to given that;
Green Frog convenience store supplies two types of protein bars.
And, One protein bar has 320 calories in the 2-ounce size.
Now,
For 1 ounce size, calories in One protein bar = 320 / 2
= 160
Hence, We get;
For 3 ounce size, calories in One protein bar = 160 x 3
= 480
Thus, There are 480 calories are in the 3-ounce size of the bar.

⚠️THIS IS DUE TODAY⚠️ USE DISTRIBUTIVE PROPERTY
Answer:
4x + 8
-45 - 5x
7x - 21
Step-by-step explanation:
For the first one
4(x + 2)
for distributive property you multiply the number or symbol next to the outside of the parenthesis, by everything inside the parenthesis.
4(x+2)
4*x = 4x
4*2 = 8
So, this is 4x + 8
-5(9+x)
-5*9= -45
-5*x=-5x
So, this is -45 - 5x
7(x-3)
7*x= 7x
7*-3= -21
This will be 7x - 21

If a factor of a polynomial is x-5, what is the zero?
Answer:
x = 5
Step-by-step explanation:
Because the factor of the polynomial is x - 5, we can infer that the zero would be the solution of this equation: x - 5 = 0
Therefore, the zero is x = 5.

What is the value of x in the figure?
The sun of the first 3 terms of an arithmetic sequence is 21 while their product is 315 determine these three terms?
Answer:
The terms of the sequence are x=5 and a=2:
[tex] x + (x + a) + (x + 2a) = 21 [/tex] → [tex] 5 + (5 + 2) + (5 +2*2) = 21 [/tex]
[tex] x*(x + a)*(x + 2a) = 315 [/tex] → [tex] 5*(5 + 2)*(5 + 2*2) = 315 [/tex]
Step-by-step explanation:
We can find the terms of the following sequence:
[tex] x + (x + a) + (x + 2a) = 21 [/tex]
[tex] 3x + 3a = 21 [/tex]
[tex] x + a = 7 [/tex] (1)
The product of that sequence is:
[tex] x*(x + a)*(x + 2a) = 315 [/tex] (2)
Solving equation (1) for x:
[tex] x = 7 - a [/tex] (3)
And by entering (3) into (2):
[tex] (7 - a)*(7 - a + a)*(7 - a + 2a) = 315 [/tex]
[tex] 7*(7^{2} - a^{2}) = 315 [/tex]
[tex] 343 - 7a^{2} = 315 [/tex]
[tex] a = 2 [/tex]
Now, by entering "a" into equation (3):
[tex] x = 7 - 2 = 5 [/tex]
Therefore, the terms of the sequence are x=5 and a=2.

So first you would have to find the slope using the two points and the equation: y2-y1/x2-x1, which in this case means you take 6+4/3+1, which would be a slope of 10/4 or 5/2, or 2.5. Using this, we can take a point, use point slope form, and rearrange it. So:
y-6=2.5(x-3)
y-6=2.5x-7.5
-2.5x+y=1.5

Jim borrows $210 from his sister at an 8% interest for seven years. How much interest does Jim have to pay?
Answer:
$117.6
Step-by-step explanation:
Formula:
I = Prt
Given:
P = 210
r = 8% = 0.08
t = 7
Work:
I = Prt
I = (210)(0.08)(7)
I = 117.6
Answer:
Step-by-step explanation:
So with 8% interest, Jim will have to pay 8% more each year. For the first year we need to multiply 210 with 1.08 to find the amount that Jim would have had to pay to his sister if he had gotten an 8% interest for 1 year. Every time the year increases we need to multiply the previous number with 1.08 because we are looking for the 8% increased value of the previous one, therefore our equation is:
P(t) = 210*(1.08)^t --> (t=time in years, P(t)=amount of money Jim need to pay back with respect to time)
Since Jim gets an 8% interest for 7 years we have to put in 7 for t.
P(7)=210*(1.08)^7
which is approximately $359.903

The minute hand of a clock moves from 12:10 to 12:30 a. How many degrees does the minute hand move during this time? b.How many radians does it move during this time?
Answer:
a. 120 degrees
b. 2.0944 radians
Step-by-step explanation:
From 12:00 to 12:15 there forms a 90 degree angle. If we divide this by 3 we get that every 5 minutes the hand moves 30 degrees. Since in this scenario, the minute hand moved from 12:10 to 12:30 it, therefore, moved a total of 20 minutes so we can do the following math
20 / 5min = 4 times
4 * 30 degrees = 120 degrees
We can see that in this time it moved a total of 120 degrees. Now we can use this value to turn it into radians using the degree to radians formula
degrees * [tex]\pi /180[/tex] = radians
120 * [tex]\pi / 180[/tex] = radians
2.0944 = radians
