A sphere has a diameter of 12 ft. What is the volume of the sphere? Give the exact value in terms of Pi.
Formula of volume of a Sphere is : V = 4/3 πr³
Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet
Substitute it into the formula,
V = 4/3 π(6)³
V = 4/3 *216π
V = 288π Ft² [ Answer in the term of π ]
You can also solve it for numeral value by substituting the value of π = 22/7
V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]
Answer:
288 pi ft squared

your original percentage =100percent
your new percentage:100+16
=116percent
old. new
value. 42. x
percentage 100. 116
cross multiply :x multiply by 100=42 multiplyby 116

Are the 2 lines:
y = 4x - 3 and y = (1/4)x +3
Parallel, Perpendicular, or Neither?
Please let me know an explanation would be great I hate my math teach but thank you!
Answer:
Step-by-step explanation:
Both equations are in slope-intercept form, so the coefficient of x is the slope of the line.
y = 4x-3
slope = 4
y = (¼)x + 3
slope = ¼
If the slope are the same, the lines are parallel. If the product of the slopes = -1, the lines are perpendicular.
4×¼ = 1
The lines are neither parallel nor perpendicular.
An angle measures 10° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The two angles are 85 and 95 degrees
Step-by-step explanation:
Supplementary angles add to 180
Let x be one angle
The supplement is 10 less, ( x-10)
They add to 180
x+ ( x-10) = 180
2x -10 = 180
Add 10 to each side
2x-10+10 =180-10
2x= 190
Divide by 2
2x/2 =190/2
x=95
The other angle is 95-10 = 85
The two angles are 85 and 95 degrees

Two shirts and one jumper cost £29
One shirt and one jumper cost £21
How much does one jumper cost?
£
Answer:
Jumper costs £13
Step-by-step explanation: (s = shirt j = jumper)
We know that 2s + 1j = £29
We also know that 1s + 1j = £21
29-21 = £8
This means that the shirts cost £8 each
We now need to multiply: 8 x 2 = £16 which means that the shirts in total cost £16
So, 29 - 16 = £13 which means one jumper costs £13
The cost of one jumper is $13.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, two shirts and one jumper cost £29 while one shirt and one jumper cost £21, we need to find the cost of one jumper,
Let jumper is represented by j and that of shirt by s,
Establishing the equations,
2s + j = 29
j = 29 - 2s......(i)
s + j = 21
j = 21 - s.......(ii)
Solving the equations,
21 - s = 29 - 2s
s = 8
Put s = 8 in eq (ii)
j = 21 - 8
j = 13
Hence, the cost of one jumper is $13.

What is the slope-intercept equation of a line with slope 2.5 and y-intercept -8?
Answer:
y = 2.5x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2.5 and c = - 8 , then
y = 2.5x - 8 ← equation of line
