find the volume of the sphere
The volume of the sphere is 22/ 336 cubic units
How to determine the volumeThe formula for volume of a sphere is expressed as;
Volume = [tex]\frac{4}{3} \pi r^3[/tex]
Where;
π = 22/ 7radius, r = 1/ 4Substitute the values into the formula;
Volume = 4/ 3 × 22/ 7 × (1/ 4)³
Volume = 4/ 3 × 22/ 7 × 1/ 64
Multiply through
Volume = 88/1344
Volume = 22/ 336 cubic units
Thus, the volume of the sphere is 22/ 336 cubic units

A television screen, length is 16 1/2 inches, width is w inches, and area is 462 square inches. Select all THREE equations that represent the relationship of the length, width, and area of the television.
Answer:
it's B, C, and D
Step-by-step explanation:
A. w ⋅ 462 = 16 1/2
not A
w * a ≠ l
B. 16 1/2 ⋅ w = 462
is B
l * w = a
C. 462 ÷ 16 1/2 = w
is C
a / l = w
D. 462 ÷ w = 16 1/2
is D
a / w = l
E. 16 1/2 ⋅ 462 = w
not E
l * a ≠ w

3x+2y=7 y=3x-19 could someone show me a step by step for this equation for substitution
Answer:
[tex]\boxed {\boxed {\sf (5,-4)}}[/tex]
Step-by-step explanation:
We are given the equations:
[tex]3x+2y=7 \\y=3x-19[/tex]
Since we know what y is equal to, we can substitute that expression in for y in the first equation.
[tex]3x+2(3x-19)=7[/tex]
Distribute the 2. Multiply each term inside the parentheses by 2.
[tex]3x+(2*3x)+ (2*-19)=7[/tex]
[tex]3x+6x+-38= 7[/tex]
Combine the like terms (the terms with variables).
[tex]9x-38=7[/tex]
Since we are solving for x, we must isolate the variable. 38 is being subtracted and the inverse of subtraction is addition. Add 38 to both sides.
[tex]9x-38+38=7+38 \\9x=7+38\\9x=45[/tex]
Now x is being multiplied by 9. The inverse of multiplication is division. Divide both sides by 5.
[tex]9x/9=45/9\\x=45/9\\x=5[/tex]
Now we know what x is equal to and can substitute the value into the second equation.
[tex]y=3x-19[/tex]
[tex]y=3(5)-19[/tex]
Multiply.
[tex]y=15-19[/tex]
Subtract.
[tex]y= -4[/tex]
Coordinate points are written as (x,y). Therefore, the solution is (5, -4).
Answer:
x=5,y=-4
Step-by-step explanation:
[[tex]\frac{3x+2y=7}{y=3x-19}[/tex]][3x+2(3x-19)=7][9x-38=7]y=3 · 5 - 19x=5,y=-4Froyo, a frozen yogurt store, has designed a cylindrical container for a new vanilla

Find the missing dimension use the scale factor 1:12 model 32 cm find the actual in m
Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.
[tex]\dfrac{1}{12}=\dfrac{32}{x}[/tex]
On cross multiplication, we get
[tex]x=32\times 12[/tex]
[tex]x=384\ cm[/tex]
[tex]x=3.84\ m[/tex] [tex][\because 1\ m=100\ cm][/tex]
Therefore, the actual dimension is 3.84 m.
2 Find the area of circle with al
diameter of 28 meters (m). Use
3.14 for pi.
(28m
Answer:
615.44
Step-by-step explanation:
The area of a circle is pi x r^2
To get the radius (r) you divide the diameter (28) by 2. Which would be 14.
Then you just fill in the numbers into the formula
3.14 x 14^2
Which is 615.44
Which situation is best represented by the equation y=5x + 10?
Answer:
x=1/5y-2
Step-by-step explanation:
Step 1: Flip the equation
5x+10=y
Step 2: Add -10 to both sides
5x+10+-10=y+-10
5x=y-10
Step 3: Divide both sides by 5.
5x/5 =y-10/5
x=1/5y-2

This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid! Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.
IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid
The volume of a square pyramide is .....
V = side² × (height / 3)
The volume of a rectangular pyramide is .....
V = base area × (height / 3)
= length × width × (height / 3)
= 12 × 6 × 10 / 3 cm³ BUT REMEMBER we want only HALF of the
= [12 × 3 × 10] divide by 2 cm³ Rectangular pyamid
Volume of the image shown in the diagram is ....
= 360 / 2 cm³
= 180 cm³ <----------------- Final Answer

Determine the number of terms n :
a 1 = 15, a n = 79, S n = 423
Answer:
The number of terms in the sequence is 9
Step-by-step explanation:
We want to get the number of terms
Mathematically, we have the formula for the sum of terms in an arithmetic sequence as
[tex]sn = \frac{n}{2} (a + 1)[/tex]
a represents the first terms, and i represent the last term
[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Alright so we just need to find the percentage values of the discount and tax
What is 10%?:
x/800 = 10/100
8000 = 100x
x = 80
800 - 10%
800 - 80 = 720
What is 8%?:
x/800 = 8/100
6400 = 100x
x = 64
720 + 8%
720 - 64 = 784
