What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The graph is given below.
The geometry is defined by the combination of rectangular prism and half-cylinder. Then the volume of the composite geometry will be
Volume = [(πr²/2) + a x b] x h
Volume = [(π x 4.5²/2) + 9 x 2] x 16
Volume = [10.125π + 18] x 16
Volume = 48.808 x 16
Volume = 796.938

How do I solve for 4h=57.6
Pls explain bc I don’t understand Does h = 14.4
Answer:
h = 14.4
Step-by-step explanation:
4h=57.6
Divide each side by 4
4h/4 = 57.6/4
h = 14.4
Answer:
See explanation
Step-by-step explanation:
Always divide the constant by itself and the value it equals.
1) Divide both sides by 4.
[tex]h=\frac{57.6}{4}[/tex]
2) Simplify [tex]\frac{57.6}{4}[/tex] to [tex]14.4[/tex].
h = 14.4
To check our answer,
4h = 57.6
1) Let h = 14.4
4 * 14.4 = 57.6
2) Simplify 4 × 14.4 to 57.6.
57.6 = 57.6

Question Bill needs 864 tiles to tile a bathroom. He can buy tiles individually for $0.40 each, and he can buy them in boxes of 100 for $32.50 per box. What is the least amount that Bill must pay to buy the tiles he needs
The least amount that Bill must pay to buy the tiles he needs is $292.50
What is the least amount?The total cost of buying the tiles individually is : cost per tile x total tiles needed
$0.40 x 864 = $345.60
The total cost of buying the tiles in a box of 100 is : $32.50 x 9 = $292.50

Reflect the figure over the line x = 0.
The coordinate of J’ is ?
The coordinate of K’ is ?
After the reflection over the line x = 0, the coordinates will be:
J' = (2, 1)
K' = (0, 4) = K
How to find the coordinates after the reflection?For any point (x, y), if we apply a reflection across the line x = 0, the image after the reflection will be (-x, y).
So it only changes the sign of the x-component.
In the graph, we can see that J = (-2, 1). So after the reflection, we will have:
J' = (2, 1).
And we also can see that K = (0, 4), then after the reflection, we have:
K' = (-0, 4) = (0, 4) = K
So point K does not change under that reflection.

Given the following formula, solve for I.
P = 2(1 + 6)
PLEASE HELP!!!
Step-by-step explanation
Here ...I'm not too sure about the question as you have written
P = 2 ( 1 + 6 ) and ask to solve for L ...
.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.
...So let me correct the question....
P = 2 ( l + 6 )
P = 2l + 12
P - 2l = 12
- 2l = 12 - P
- 2l = - P + 12
Change the sign of both side of the equation...
2l = P + 12
divide both side by the same number...
L = ( P + 12 ) ÷ 2
[tex]l = \frac{1}{2} p - 12 \times \frac{1}{2} \\ [/tex]
Calculate the product of rational numbers...
[tex]l = \frac{1}{2} p - 6 \\ [/tex]

groups, A and B, of size 10. In the simulations, group A always plays the role of the treatment group and group B the role of the control group.
After each simulation, she subtracts the average for group A from the average for group B. The distribution of the differences for all 100 simulations is shown in the histogram.
In the original experiment, the average for the treatment group was 1.6 lower than the average for the control group.
In what percentage of simulations is the average for group A at least 1.6 lower than the average for group B?
The percentage of simulations where the average for group A is at least 1.6 lower than the average for group B is 48%.
Data points where the average for group A is at least 1.6 less than BThe following are the data points from the histogram where the average of group A is at least 1.6 less than average of group B.
At least -1.6 lower implies -1.6, -1.5, -1.4, -1.3, -1.2, -1.1, 0, 1, etc.
the first point = (-1.6 - 1.2) (number of simulation = 1)second point = (-1.2, -0.8) (number of simulation = 8)third point = (-0.8, -0.4) (number of simulation = 16)fourth point = (-0.4, 0) (number of simulation = 23)Outcome of simulations = 1 + 8 + 16 + 23 = 48

Find the surface area of the figure?
Step-by-step explanation:
the surface area consists of 6 individual areas :
front and back (both are equal)
left and right (both are equal)
top and bottom
front and back are trapezoids.
the area of a trapezoid is
(base 1 + base 2)/2 × h
the bases are the 2 parallel sides.
in our case the area of one trapezoid is
(5 + 19)/2 × 12.1 = 145.2 ft²
front and back together then are 290.4 ft².
left and right are 8×14 rectangles:
8×14 = 112 ft²
together they are 224 ft².
the bottom is a 5×8 rectangle :
5×8 = 40 ft²
the top is a 19×8 rectangle :
19×8 = 152 ft²
so, the total surface area is
290.4 + 224 + 40 + 152 = 706.4 ft²

(a) m/SQT =
(b) m/RQS =
Using the tangent theorem and the inscribed angle theorem, we have:
a. m∠SQT = 74°; b. m∠RQS = 16°.
What is the Tangent Theorem?Angle formed at the point of tangency between the tangent and the radius of a circle = 90 degrees based on the tangent theorem.
What is the Inscribed Angle Theorem?The inscribed angle theorem states that, measure of inscribed angle = 1/2(measure of intercepted arc).
a. Find m(SQT):
m∠RQT = 90° [tangent theorem]
m(QR) = 180° [semicircle]
m(QRS) = 212° [given]
m(RS) = m(QRS) - m(QR) = 212 - 180 = 32°
m∠RQS = 1/2[m(RS)] [inscribed angle theorem]
m∠RQS = 1/2(32)
m∠RQS = 16°
m∠SQT = m∠RQT - m∠RQS = 90 - 16
m∠SQT = 74°
b. m∠RQS = 1/2(32)
m∠RQS = 16°

How many solutions does this system

6x+3y = 9
2x + y = 3
Answer:
The system of equation has infinite solution.
Step-by-step explanation
2x + y = 3
6x = 9 – 3y
First we re-write the second equation in standard form
So, we add 3y both sides
6x+3y=9 ---------------- (2)
2x+y = 3----------------- (1)
3(2x)+3y = 3(3)
6x+3y=9
6x-6x + 3y-3y = 9-9
0=0

A. 8m/4
B. 9m/4
C. 3m+24/4
