Work out the volume of this sphere.
Give your answer to 1 decimal place.
Spheres
Vol = ener
7 cm
Answer:
Volume of the sphere ( V ) = 1436.02 cm³
Step-by-step explanation:
Explanation:-
Given that the radius of the sphere r = 7 cm
Volume of the sphere
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
[tex]V = \frac{4}{3} \pi (7)^{3}[/tex]
[tex]V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02[/tex]
V = 1436.02 cm³
Volume of the sphere
V = 1436.02 cm³
Answer:1436.8
Step-by-step explanation:
4/3πr^3
Substitute the 7 with the ”r”
4/3xπx7^3
=1436.8 (to 1 decimal place)

Jason has 34 raspberry scones and 51 blackberry scones. He wants to make as many identical bags of scones as possible. Each bag should have an equal number of raspberry scones and an equal number of blackberry scones. What is the greatest number of bags Jason can fill? Explain how you know.
Answer: The greatest number of bags Jason can fill = 17
Step-by-step explanation:
Given: Jason has 34 raspberry scones and 51 blackberry scones.
To make identical bags of scones as possible.
Each bag should have an equal number of raspberry scones and an equal number of blackberry scones.
The greatest number of bags Jason can fill = Greatest common divisor of 3
and 51.
= 17 [Since 34 = 2 x 17 , 51 = 3 x 17]
Hence, the greatest number of bags Jason can fill = 17
A. A cylinder just fits into a cube of side length 36 m Calculate the percentage
of empty space in the box.
Answer:
21.5%
Step-by-step explanation:
volume of cube: 36x36x36
volume of cylinder: πx18²x36
Cylinder percentage: (πx18²x36) / 36x36x36 = π / 4 = 0.785
percentage of empty space: 1 - 0.785 = 0.215 (21.5%)

Working together, two ants named Aran and Beatrice can build an ant hill in 10 hours. Aran and Charlie can build the ant hill in 12 hours. Beatrice and Charlie can build the ant hill in 15 hours. How long, in hours, will it take to build the ant hill if Aran, Beatrice, and Charlie work together?
Here we have a problem of rates of work, we want to know how long will take the 3 ants to build an ant hill if they work together.
We will find that working together, they need to work for 8 hours.
----------------------------------
Let's start by defining the variables that we will use:
A = rate at which Aran worksB = rate at which Beatrice works.C = rate at which Charlie works.Now let's see the given information:
"Aran and Beatrice can build an ant hill in 10 hours"
This can be written as:
(A + B)*10 h = 1 ant hill
"Aran and Charlie can build the ant hill in 12 hours"
This can be written as:
(A + C)*12 h = 1 ant hill
"Beatrice and Charlie can build the ant hill in 15 hours"
This can be written as:
(B + C)*15 h = 1 ant hill.
Then we have 3 equations:
[tex](A + B)*10 h = 1[/tex]
[tex](A + C)*12 h = 1[/tex]
[tex](B + C)*15 h = 1[/tex]
Where for commodity, I removed the "ant hill" unit.
Now we need to solve this system of equations, to do it, we need to isolate one variable in one of the equations and then replace it on another equation.
I will isolate A in the first equation:
[tex]A = \frac{1}{10h} - B[/tex]
Now we can replace it in the second equation to get:
[tex](\frac{1}{10h} - B + C)*12h = 1[/tex]
Now we can isolate C in the last equation to get:
[tex]C = \frac{1}{15h} - B[/tex]
Replacing that in the above equation we get:
[tex](\frac{1}{10h} - B + \frac{1}{15h} - B)*12h = 1\\\\\frac{1}{6h} - \frac{1}{12h}= 2*B\\\\\frac{1}{2}*\frac{1}{12h} = \frac{1}{24h} = B[/tex]
This means that Beatrice alone would construct the hill in 24 hours.
Now that we know the value of B, we can use:
[tex]C = \frac{1}{15h} - B = \frac{1}{15h} - \frac{1}{24h} = \frac{1}{40h}[/tex]
This means that Charlie needs 40 hours to finish the hill alone.
Finally, we can use [tex]A = \frac{1}{10h} - B[/tex] to find the value of A:
[tex]A = \frac{1}{10h} - B = \frac{1}{10h} - \frac{1}{24h} = \frac{7}{120h}[/tex]
Now if the 3 ants work together, the total rate at which they work is:
[tex](A + B + C) = (\frac{7}{120h} + \frac{1}{40h} + \frac{1}{24h} ) = 0.125 h^{-1}[/tex]
This means that they need to work for the inverse of that rate
[tex]\frac{1}{0.125h^{-1}} = 8h[/tex]
Working together, they need to work for 8 hours to complete an ant hill

1. Two linear functions are shown below. Which function has the greater
rate of change?
Answer:
Function A
Step-by-step explanation:
Function A rate of change:
Using two given pairs of values, (4, 32) and (8, 44):
Rate of change = ∆y/∆x
= (44 - 32)/(8 - 4)
= 10/4
Rate of change = ⁵/2
Function B rate of change:
Using two points on the line, (2, 4.5) and (4, 6.5):
Rate of change = ∆y/∆x
= (6.5 - 4.5)/(4 - 2)
= 2/2
Rate of change = 1
Function A has the greater rate of change
Function A has the greater rate of change.
Here, we have,
Function A rate of change:
Using two given pairs of values, (4, 32) and (8, 44):
Rate of change = ∆y/∆x
= (44 - 32)/(8 - 4)
= 10/4
=5/2
Rate of change = 5/2
Function B rate of change:
Using two points on the line, (2, 4.5) and (4, 6.5):
Rate of change = ∆y/∆x
= (6.5 - 4.5)/(4 - 2)
= 2/2
Rate of change = 1
Function A has the greater rate of change.

Use the Law of Cosines to solve for the side BC. Round your answer to the point
nearest whole number. Write the value only *
Answer:
BC = 50
Step-by-step explanation:
Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cosy (c is BC)
c^2 = 30^2 + 21^2 - 2(30)(21)cos123
c^2 = 900 + 441 - 1260*(-0.888)
c^2 = 1341 - (-1118.841)
c^2 = 2459.841
c = 49.597

Paul won 37 super bouncy balls playing hoops at county fair. At school he gave two to every student in his math class. He only had 3 remaining. How many students are in his class?
Answer:
17 students
Step-by-step explanation:
If he started with 37 and ended with 3 we have to subtract those three first so that we know how many we are actually working with so, 37-3=34. 34 balls is the amount distributed among the class. 34/2 is 17.

f(x)=2x+3
f(x)=0
2x+3=0
2x=-3
x=-3/2
x=-1.5
when x=0,y=f(x)=2(0)+3=3
so one point is (0,3)
when x=2,y=f(x)=2(2)+3=4+3=7
so point is (2,7)
Draw a line through (0,3) and (2,7)
see where it cuts x-axis.
it is the zero of the linear equation.
