Answer:

=10x2−8

Step-by-step explanation:

4(x2−5)+2(3x2+6)

Distribute:

=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)

=4x2+−20+6x2+12

Combine Like Terms:

=4x2+−20+6x2+12

=(4x2+6x2)+(−20+12)

=10x2+−8

Hal has a steel barrel with a diameter of 6 feet that can be filled to a depth of 4.6 feet with oil. What is the volume of the b
scoray [572]

Answer:

129.996 cubic feet

Step-by-step explanation:

Assuming that the barrel is a perfect cylinder, we can use the formula to find the volume:

\pi(r)^2(h)

First, we have to find the radius, which is:

D = 2r

So the radius is 3 feet, since it is half of the diameter. Then, we plug in the values.

3.14(3)^2(4.6)

Now, we solve. Exponents are first...

3.14(9)(4.6)

Now multiply left to right.

28.26(4.6)

129.996 cubic feet

Therefore, the barrel can hold 129.996 cubic feet of oil. Hope this helps you!

For a set of five whole numbers, the mean is 4, the mode is 1, and the median is 5. What are the five numbers? Plz help me plz
solniwko [45]
Mean is the average, mode is the number that is repeated most often and the median is the middle number.  We know there are 5 numbers so, 5 is the middle as it is the median #. The mode has to appear more than once or 5 would also be a mode.
1 1 5 _ _  
M = 1+1+5+x+y /5
4 = 1+1+5+x+y/ 5
4 = 7+x+y / 5
Average of 5 numbers is 4 therefore 4 times 5 = 20
20-7 = 13, what two numbers that are more than 5 equal 13?  Only 6 &7.
4 = 1+1+5+6+7 / 5
