approximate volume of the container? Round to the nearest hundredth.
Answers
Answer:
4 181 067.1 cm3
Step-by-step explanation:
Volume = height x pi x 2r
Volume = 315 x pi x 65 x 65 = 4181067.123
4181067.123 = 4 181 067.1 cm3
Answer:
v=pi×r^2×h (315cm=3.15m and 65cm=0.65m)

Thomas is training for a 3.1-mile race by running on a circular path. He knows that it is 0.75 miles from the tree in the center of the circular path to the path. How long is the path?
Answers
Radius of circular path = distance from path to the tree in the centre
Radius of circular path = 0.75 miles
Length of path = Circumference of path(circle)
Circumference of the circular path :
[tex] = \tt2\pi r[/tex]
[tex] =\tt 2 \times 3.14 \times 0.75[/tex]
[tex] =\tt 6.28 \times 0.75[/tex]
[tex] =\tt 4.71 \: miles[/tex]
Thus, the circumference of the circular path = 4.71 miles
Therefore, the circular path is 4.71 miles long.

A box with a height (x+5) has a square base with side x. A second box with height (x+2) has a square base with side (x+5). If the two boxes have the same volume, find the value of x
Answers
Answer :
x = -1.43
Explanation :
As given ,
The first box has a height (x+5) has a square base with side x
So, the Length and Breadth of the box are x and x respectively.
Now,
The volume of first box = Length×Breadth×Height
= (x).(x).(x+5)
= x²(x+5)
⇒The volume of first box = x²(x+5)
Now,
Given that , the second box with height (x+2) has a square base with side (x+5).
So, the Length and Breadth of the box are (x+5) and (x+5) respectively.
Now,
The volume of second box = Length×Breadth×Height
= (x+5). (x+5).(x+2)
= (x+5)²(x+2)
⇒The volume of second box = (x+5)²(x+2)
Now,
Given that, the two boxes have the same volume
⇒x²(x+5) = (x+5)²(x+2)
⇒x² = (x+5)(x+2)
⇒x² = x² + 2x + 5x + 10
⇒x² - x² = 7x + 10
⇒0 = 7x + 10
⇒ 7x = -10
⇒ x = -[tex]\frac{10}{7}[/tex] = -1.43
⇒ x = -1.43
As volume of first box = x²(x+5) = (-1.43)²(-1.43+5) = 7.30 ≈ 7
As volume of second box = (x+5)²(x+2) = (-1.43+5)²(-1.43+2) = 7.26 ≈ 7
At x = -1.43, Volume of both the boxes are same.

Which one is it -28 -25.6 -22.4 or -20
Answers
Answer:
x = -20
Step-by-step explanation:
2.5(x - 4) = -60
~Distribute left side
2.5x - 10 = -60
~Add 10 to both sides
2.5x = -50
~Divide 2.5 to both sides
x = -20

In 1959, Russia sent the Luna 1 spacecraft towards the moon. It made 3.8x10 to the 5th power kilometer trip to the moon in 2.16x10 to the 3rd minutes. Write and expression for the speed of Luna 1 in kilometers/minute. Represent this expression as a quotient of two numbers expressed in scientific notation
Answers
The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.
The formula to calculate speed is Speed = distance/time.
So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.

Ryan drove 480 miles and used 20 gallons of gas. How many miles did Ryan's car get per gallon? Write an equation that would solve this problem.
Answers
Answer:
24 miles per gallon
Step-by-step explanation:
Step one:
given data
total distance covered= 480miles
The total amount of gallons used is = 20
The miles per gallon
= 480/20
=24 miles per gallon
Step two:
hence the equation that we used in solving the problem is stated as
miles per gallon= total distance/total gallon sused
Mr Dyson bought 5 gallons of paint. He used 3/4 of the 5 gallons to paint his house.
How much paint did Mr. Dyson use?
A 3 3/4 gallons
B 4 1/4 gallons
C 4 3/4 gallons
D 3 1/4 gallons
Answers
Answer:
I think 3 3/4 (A)
Step-by-step explanation:
Each gallon is 20 percent, while 3/4 is 75 percent. Divide 20 by 4, which is the denominator. The answer is 5. Every time you get a 5, that's a 1/4. For example:
25: 1 1/4
30: 1 2/4 (1/2)
35: 1 3/4
40: 2
Now, 75 is between 3 and 4 gallons, but it is lower than 4, so B and C are wrong. Let's do the math again.
65: 3 1/4
70: 3 2/4 (1/2)
75: 3 3/4
Remember, 3/4 is about 75%. which means, A is the answer!

What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
Quadratic equation,
m/(m+4) + 4/(4-m) = m²/ (m²- 16)
Simplifying,
{m(4-m) + 4(4+m)}/(4²-m²) = m²/ (m²- 16)
4m - m² + 16 + m² = m²/ (m²- 16) x (-(m²- 16))
-m² + 4m+16 = -m²
4m + 16 = 0
4m = -16
m = -4
Therefore, the value of m is -4.
