Find the volume of the beach ball and the volume of the toy ball. How many times greater is the volume of the beach ball than the volume of the toy ball?
A.THE VOLUME OF THE BALL IS 904 CUBIC INCHES. b. THE VOLUME OF THE BEACH BALL IS 678 CUBIC INCHES. c.the volume of the beach ball is 452 cubic inches
Answers:
Volume of beach ball = 904 cubic inchesVolume of toy ball = 113 cubic inchesThe beach ball is 8 times greater compared to the toy ball===============================================
Work Shown:
Beach ball
V = volume of sphere
V = (4/3)*pi*r^3
V = (4/3)*3.14*(6)^3 .... the beach ball has diameter 12, so radius is 6
V = 904.32
V = 904 cubic inches is the approximate volume of the beach ball
------------------------
Toy ball
V = volume of sphere
V = (4/3)*pi*r^3
V = (4/3)*3.14*(3)^3 .... the toy ball has diameter 6, so radius is 3
V = 113.04
V = 113 cubic inches is the approximate volume of the toy ball
--------------------------
Divide the two volumes to find that 904/113 = 8
This means that the beach ball is 8 times greater in volume compared to the toy ball
We can say
[tex]\text{Beach ball volume} = 8*\left(\text{toy ball volume}\right)[/tex]
The beach ball's volume is 7238.23and if we round that would be 7238 and the volume for the toy ball is 904.78 and if we round that it would be 905.So, it's around 7 times greater. The difference after they are rounded is 6,333.

Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake. His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet. What is the vertical distance between Dan and Jeff? Please show work.
Answer:
The vertical distance between Dan and Jeff is of 26 feet.
Step-by-step explanation:
Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.
His position is -34 feet.
His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.
Dives to 40 feet, and descends 20 more feet. So
-(40 + 20) = -60
What is the vertical distance between Dan and Jeff?
|-34 - (-60)| = |-34 + 60| = 26
The vertical distance between Dan and Jeff is of 26 feet.

Find the 89th term of the arithmetic sequence 25, 35, 45, ...
Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905

Scarlett walks along the edges of a
rectangular path from A to B to C to D, a
distance of 38 metres. Jake walks along the
same rectangle, but from B to C to D to A,
a distance of only 31 metres.
What is the area, in square metres, of rectangle ABCD?
D
С
Answer:
168 meters squared
Step-by-step explanation:
So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.
So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m
38-14=24
so now we know that the side is 24 and we can solve for the area
24*7=168
so the answer is 168 meters squared

Answer:
1) 63cm²
2)28.27cm²
(dont put the cm² in your answer though since its already there)
Step-by-step explanation:
Surface area of the cardboard part formula :
Base × Height
you have the radius going half way so add another 3cm to make it 6cm so you have the full length
6 x 10.5= 63cm²
Plastic part of the can :
[tex]\pi \: r^{2} [/tex]
3cm is your radius so.
[tex]\pi \times 3 ^{2} = 28.27433388[/tex]
but its asking you to round to the nearest hundredth so
28.27cm²

What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°
1) f(x) = x 2+ 3x - 18 2) g(x) = x 2+ 2x - 120 3) h(x) = x 2+ 7x - 17 4) k(x) = x 2+ 9x + 20.25 5) s(x) = 4x 2– 5x - 21 6) t(x) = 16x 2+ 9x + 20 7) f(x) = -2x 2+ 10x - 5 8) r(x) = -3x 2- 5x + 2
Find the product of 2/3 and 9/10
4 points
Answer:(2/3) + (9/10) = 47/30
= 1 17/30
Step-by-step explanation:
Answer:
Step-by-step explanation:
2/3 x 9/10
=(2x9)/ (3x10)
=18/30
The simplest form of 18/30 is 35.
How I got this answer: First you need to write out your equation, Then you need to multiply like so, Take the first number of your first equation and multiply it by the first number in the second equation then do that for your second like this (2x9) and take (3x10) mulitply both and you get 18 for the first then 30 for the second, if you need that in simplest form. then it will be 35. Hope this helps Have a wonderful day

Answer:
20
Step-by-step explanation:
Solve the following quadratic equation for all values of x in simplest form.
20+ 2x= 28
Answer:
x = 4
Step-by-step explanation:
To solve, we need to isolate x.
Start by moving the 20 to the other side by subtracting it from both sides.
2x = 8
Since x is being multiplied by 2, we need to divide both sides by 2 to move it to the other side.
x = 4

Make a table with the following information:
Cans: 0, 2, 4, 6
Cost:
Equation:
Answer:
$12,$11,$10,$9
Step-by-step explanation:
As the starting price is $12, the first piece of information they give you is the number of cans + the discount each one gives, meaning that the table should have two titles being cost and cans. The number of cans should be at the top with the price being put below for example.
cans: 0 2 4 6
cost: 12 11 10 9
that is the table; the equation to figure this out would be
if you say that 1 can is = to "x"
then the equation becomes much easier to write down and you can simply write it down for each price
cost = 12
cost = 12 - 2x = 11
cost = 12 - 4x = 10
cost = 12 - 6x = 9
making x worth 0.5
Answer: $12,$11,$10,$9

A classroom is arranged with 6 seats in the front row, 8 seats in the middle row, and 10 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom.
What is the probability that the first student who enters the classroom will be assigned a seat in the front row?
Answer:
[tex] \frac{6}{24} \: or \: 0.25 \: or 25\%[/tex]
Step-by-step explanation:
First add them all up to get the total amount of seats.
6+10+8=24
there are 6 seats in the front row. so that means it will be
[tex] \frac{6}{24} [/tex]
24÷6=0.25
0.25×100=25%
Probability can be answered with a fraction, decimal or a percentage, they are all correct.
Distributive Property. Show work below.
1/5(5r+10) - 3(r-2)
Answer:
The answer is -2r + 8.
Step-by-step explanation:
1) Simplify 1/5(5r + 10) to 5r + 10/ 5.
[tex] \frac{5r + 10}{5} - 3(r - 2)[/tex]
2) Factor out the common term 5.
[tex] \frac{5(r + 2)}{5} - 3(r - 2)[/tex]
3) Cancle 5.
[tex]r + 2 - 3(r - 2)[/tex]
4) Expand by distributing terms.
[tex]r + 2 - (3r - 6)[/tex]
5) Remove parentheses.
[tex]r + 2 - 3r + 6[/tex]
6) Collect like terms.
[tex](r - 3r) + (2 + 6)[/tex]
7) Simplify.
[tex] - 2r + 8[/tex]
Thus, the answer for this equation is -2r + 8.
48 is 12% of what number?
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400

Fred's car can travel 36.8 miles on one tank of gas. His gas tank holds 16 gallons. How many miles can Fred's car travel per gallon?What is the solution of the equation below? x+8.63=11.001
Answer:
Answer to Question 1: 2.3 miles per gallon
Answer to Question 2: x = 2.371
Step-by-step explanation:
Question 1 (explanation): 36.8 (miles on one tank of gas) / 16 (gallons of gas that Fred's car hold) = 2.3 (miles that Fred's car can travel per gallon)
Question 2 (explanation): 11.001 - 8.63 = 2.371

Change 60% to fraction in its simplest form
Answer: 3/5
Step-by-step explanation:
60% as a fraction is 60/100.
You can simplify 60/100 to 30/50 then simplify that further to 15/25 then using the 5 times tables you can simplify that to 3/5.
