If a sphere fits snugly inside a cube with 34-in edges. What’s is the approximate volume of the space between the sphere and cube
Answers
The volume of the space between the sphere and cube is equal to the volume of the sphere subtracted from the volume of the cube:
The volume of a cube is:
s is the length of each edge in the cube
The volume of a sphere is:
The diameter of the sphere is equal to the edge of the cube, then, its radiusr is:
Then, the volume of the space between the sphere and cube is:
s is 34 in

did he walk in one hour?
A 14,520 ft
B 21,120 ft
C 29,040 ft
D 58,080 ft
Help?
Answers
Answer:
A. 14,520 ft
Step-by-step explanation:
To start off this problem, we need to find how many miles James walks per hour. To do that, lets divide 11 by 4.
Next, since 5,280 feet are in a mile, we need to multiply 2.75 by 5,280:
James walked 14,520 ft. in one hour.

% off= 20%
Sale $= $680
STEP 1:
Find discount amount
Discount Amount= % off * Original $
= 20% * x
change % to decimal (% ÷ 100)
= 0.20 * x
= 0.20x
STEP 2:
Find sale price
Sale Price= Original $ - Discount
= x - 0.20x
= 0.80x
STEP 3:
Sale= $680= 0.80x
Solve for x
$680= 0.80x
divide both sides by 0.80
$680/0.80= x
$850= x
ANSWER: The original price is $850

Which of the following could represent the measures of the three angles?
Ox, 2%, 4%
OX, 2x, 3x
OX, 2x, 2x
Answers
Answer:
x, 2x, 3x
Step-by-step explanation:
If we have angle x as one angle, and the 2nd angle is twice the angle, the 2nd angle will be 2x. If the 3rd angle is the sum of the 1st angle and the 2nd angle, we have 2x + x, which equals 3x.

ANSWE,LET two numbers be A and B then
A+B=52
A-B=14....linear equation in 2 variable
adding 2 eqns
2A=66... dividing both side by 2
A=33
and put A=33 in eqn A+B=52
B=52-33
B=19.
SO. LARGER NUMBER=33
Smaller number=19
1-5x-2y =-22
a) (-4,-6)
b) (6,4)
Answers
According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:
x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
