Find the volume of the cone. Round your answer to two decimal places.
Answer:
Step-by-step explanation:
Volume of the cone, V=1/3*Π*r^2*h
we have the slant height, and we need to find the h, height
a^+b^2=c^2
where c is 13
169=25+h^2
h^2=144
h=12
V=1/3*3.14*25*12=100*3.14=314.15 ft^3

x is greater than or equal to 3. x ≥ 3
Step-by-step explanation:
Answer:
x ≥ 3
Step-by-step explanation:
The arrow goes to the right, the dot is shaded in and x is at 3.
Therefore, x ≥ 3.
How am I supposed to do this?
For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)
#9-Step by step
Q=25[tex]\pi[/tex]h
divide 25[tex]\pi[/tex] on both sides of the equation
Q/25[tex]\pi[/tex]=h
h=Q/25[tex]\pi[/tex]
Since his can't be simplified any further this is your answer
#11. y=7m+6
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
#13 A=(Z+7)3
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
(A/3)-7=Z
#17. (2x/5)-9=6
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2
x=75/2
x=37.5
one number is equal to 4 times another number. their difference is 12. find the numbers
Answer:
[tex]x=16 \ \ and \ \ y=4[/tex]
Step-by-step explanation:
Suppose the numbers are x and y
One number say x is equal to 4 times another number say y
[tex]x=4y[/tex] ---------------- (1)
Their difference is 12
[tex]x-y=12[/tex] ------------(2)
Put x=4y in equation (2)
[tex]4y-y=12[/tex]
[tex]3y=12\\y=4[/tex]
Put y=4 in equation (1)

A theatre has the capacity to seat people across two levels, the Circle and
the Stalls.
The ratio of the number of seats in the Circle to the number of seats in
the Stalls is 3:5
Yesterday, the audience occupied of the seats in the Circle and
all the 1520 seats in the Stalls.
Work out the percentage of occupancy of the theatre yesterday.
You must show how you get your answer.
Answer:
C:S--------> 3:5
1520/5=304
3 x 304= 912
912+1520=2432
1520/2432 x 100
Ans = 62.5% seats occupied

The picture graph below displays the number of miles for
each leg of a triathlon, in which the participants swim 2.4
miles, bike 112 miles, and run 26.2 miles.
Triathlon Legs
= 1 mile
No, because the pictures accurately represent the
number of miles for each leg of the triathlon.
O No, because the height of each column corresponds
to the number of miles for each leg of the triathlon.
O Yes, because the pictures do not accurately
represent the proportions of the distances for each leg
of the triathlon.
O Yes, because the height of each column does not
represent the number of miles for each leg of the
triathlon.
$ = 28 miles
* = 8 miles
Number of Miles
Answer:
C.)Yes, because the pictures do not accurately represent the proportions of the distances for each leg of the triathlon.
No, because the height of each column corresponds to the number of miles for each leg of the triathlon. Then the correct option is A.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The picture graph below displays the number of miles for each leg of a triathlon, in which the participants swim 2.4 miles, bike 112 miles, and run 26.2 miles.
Then the number swim, bike, and the run symbol will be
Swim = 2.4 / 1 = 2 and 0.4
Bike = 112 / 28 = 4
Run = 26.2 / 8 = 3 and 0.275
No, because the height of each column corresponds to the number of miles for each leg of the triathlon. Then the correct option is A.

Answer:
1,600 dollars
Step-by-step explanation:
The easiest way to solve it is to find the dollar for 1 percent.
Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

5/6 = 20/24

A group of nine friends go to a baseball game. The group buys 6 hotdogs and 3 hamburgers for a total of $27.75. A hamburger costs $1.75 more than a hot dog. What is the cost of a hamburger?
Answer:
let x be cost of a hotdog
let y be cost of hamburger
so,
5x + 4y = 17.75 eq. 1
4x + 5y = 18.25 eq. 2
manipulate eq. 1 so solve for x:
5x = 17.75 - 4y
x = 17.75/5 - (4/5)y
x = 3.55 - (4/5)y eq. 3
substitute eq. 3 to eq. 2:
4(3.55 - (4/5)y) + 5y = 18.25
14.2 - (16/5)y + 5y = 18.25
14.2 + (9/5)y = 18.25
(9/5)y = 18.25 - 14.2
4.05= (9/5)y
y = 2.25
x = 3.55 - (4/5)(2.25)
x = 1.75
hotdog costs $1.75
hamburger costs $2.25

I put a ladder 1.5m away from a tree. the ladder is inclined at 70 degrees about the horizontal. What is the height of the tree?
Answer:
4.121216129m
Step-by-step explanation:
use sohcahtoa
tan(70) x 1.5m = 4.121216129m
The height of the tree is 4.12 m.
Given,
I put a ladder 1.5m away from a tree.
The ladder is inclined at 70 degrees about the horizontal.
We need to find out what is the height of the tree.
What is the formula for tangent in trigonometry?
It is given by:
Tan Ф = Perpendicular / Base
Draw a figure of the given statement.
/ | A
/ |
(ladder) / | (tree)
/. |
/. |
C /_70°_______ | B
<--------1.5m-------->
Find the AB.
AB = height of the tree.
TanФ = AB / CB
Tan 70° = AB / 1.5m
2.7474 = AB / 1.5m
AB = 2.7474 x 1.5m
AB = 4.12 m
Thus the height of the tree is 4.12 m.
