Answer:
16units
Step-by-step explanation:
Given data
The expression for the volume of a cone is given as
v=1/3πr^2h
v= 3π
r= 12
h=???
Substitute
3π= 1/3*π*12^2*h
3= 1/3*144*h
3= 144h/3
cross multiply
3*3= 144h
9= 144h
h= 144/9
h=16 units
Hence the heeight is 16units

PLS HELP ME Giving brainliest!! On Monday, 316 students went on a trip to the zoo. All 6 buses were filled and 4 students had to travel in cars. Write and evaluate an expression in terms of xx to determine how many students were in each bus.
Answer:
xx = (316 - 4) ÷ 6
xx = 52 students per bus
What is the value of BD
Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.
Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6
If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).
Is this correct???????????!!!!please gelppp
Answer:
Step-by-step explanation: it looks right to me but who knows
Answer:
Yes
Step-by-step explanation:
The line intersects the y axis at point 4 (y > 3/2 x + 4), and for every 2 squares to the right it goes 3 squares up (y > 3/2 x + 4). Also, it's the > sign, which is correct when it goes in that direction.
Solve for x: 2(2a+3)-6=5a+2
Answer:
a=-2
We move all terms to the left:
2(2a+3)-6-(5a+2)=0
We multiply parentheses
4a-(5a+2)+6-6=0
We get rid of parentheses
4a-5a-2+6-6=0
We add all the numbers together, and all the variables
-1a-2=0
We move all terms containing a to the left, all other terms to the right
-a=2
a=2/-1
a=-2
Step-by-step explanation:

Answer:
a = -2
Step-by-step explanation:
2(2a+3)-6=5a+2
distrubute the 2
4a + 6 - 6 = 5a + 2
combine like terms
4a = 5a + 2
-5a -5a
-a = 2
a = -2

Answer:
r = 3.7 cm
Step-by-step explanation:
19.02 = 1/2π(2radius) + diameter
expanding:
19.02 = 1/2(3.14)(2r) + 2r
19.02 = 3.14r + 2r = 5.14r

All you need to do is turn 33 and 44 into a fraction ([tex]\frac{33}{44}[/tex]). Then you need to simplify it and it's simplest form is [tex]\frac{3}{4}[/tex]. then you up the fraction to [tex]\frac{6}{8}[/tex] and that's your answer.
In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?
A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s
Answer:
C: 31 m/s
Step-by-step explanation:
It falls from a dam.
Thus;
Initial velocity; u = 0 m/s
Height; h = 49 m
Acceleration due to gravity is 9.8 m/s²
To solve for the final velocity this, we will use Newton's third equation of motion;
v² = u² + 2gh
v² = 0² + 2(9.8 × 49)
v = √960.5
v ≈ 31 m/s

An asteroid hit the earth and created a huge round crater. Scientists measured the distance around the crater as 26 miles. What is the area of the crater?
Answer:
53.8 mi^2
Step-by-step explanation:
First we need to determine the radius of the crater. The circumfence formula is C = 2(pi)r, and here C = 26 miles. Thus,
26 mi = 2(pi)r, so that
26 mi
r = ------------ = 4.13 miles
2pi
Then the area of the crater is A = (pi)r^2, or:
A = 3.14(4.13 mi)^2 = 53.8 mi^2

The figure is made up of a square and a rectangle. Find the area of the shaded region.
m2
please help first one correct gets barlyest
Answer:
[tex] 10 \: { \: m}^{2} [/tex]
Step-by-step explanation:
area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m
[tex] = \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2} [/tex]
Answer:
shaded region = 10 m squared
Step-by-step explanation:
Area square = 6x6 = 36 Area reatangle 4x2 = 8
both areas = 44
Now lets subtract some white parts to obtain the shaded parts
1/2 of 4x6 = 12
1/2 of 6x6 = 18
1/2 of 4x2 =4
12+18+4= 34
44-34 = 10
