8. 11/12 gallons of paint
10. 23/24 gallons of drink mix
Step-by-step explanation:
Note: When denominators are different, you must find a common denominator between the two fractions by multiplying both values
Ex: 1/3 and 1/4 = 4/12 and 3/12 common denominator is 12
8. Find the common denominator, 3/4 and 1/6, multiple the first denominator, 4, with three to get 12. Now multiply the numerator by the same number. 9/12 is our new fraction. Since the new denominator is 12, we have to get the other denominator to be 12 as well. Multiply 6 from 1/6 by 2 to get 12. Now do the same with the numerator. 2/12 is our new fraction, and all that's left is to add them together to find how much paint Damon has in total, which is 11/12 gallons.
10. Same concept as the above, 1/12 and 7/8 have a common denominator of 24, multiply 1 and 12 by two to get 2 and 24. Multiply 7 and 8 by 3 to get 21 and 24. 2/24 and 21/24 are our new fractions to add together. 23/24 is our answer.

Evaluate the expression for x = -4, y=-2, and z=-3.
x(y+z)^2?
Answer:
- 100
Step-by-step explanation:
x (y + z)²
= (-4) [(- 2) + (- 3)]²
= - 4 * (-5)²
= - 4 × 25
= - 100
Hope it helps ⚜
Step-by-step explanation:
we take the values given and we substitute in the equation above.
value of x=-4
y=-2
z=-3
hence we can solve for the equation above
-2(-2+-3)^2
we for everything in brackets first
(-2+-3)=-5
(-5)^2=25hence after solving we multiply by -2
-2(25)=-50
indeed that is my solution.
Suppose that the radius is expanding at a rate of 0.6 inches per second. How fast is the volume changing when the radius is 2.8 inches? Use at least 5 decimal places in your answer.
Answer:
59.11221 in^3/s
Step-by-step explanation:
Given dr/dt = 0.6 in/s
Find dV/dt when r = 2.8 in.
[tex]V=\frac{4\pi r^3}{3}\\[/tex]
so [tex]\frac{dV}{dr}=4\pi r^2\\[/tex]
[tex]\frac{dV}{dt}=\frac{dV}{dr}\cdot\frac{dr}{dt}=4\pi r^2\cdot\frac{dr}{dt}[/tex]
Use r = 2.8 in and dr/dt = 0.6 in/s
get
[tex]\frac{dV}{dt}=59.11221 in^3/s[/tex]

Answer:
2. P= 12
Step-by-step explanation:
Remember that if you have an exponent in your variable , what you have to do is to cancel it out by putting a square root in both sides :
√p ^2 = √144 the exponent will cancel out and then just square root 144
p = 12 that's your answer :)

An electron on an energy level has an energy of 16.32 x 10−19 J. It moves to another level by releasing 5.4 x 10−19 J of energy. Which of the following descriptions mostly likely explains what occurred?
The electron moved down to an energy level and has an energy of 10.92 x 10−19 J.
The electron moved down to an energy level and has an energy of 21.72 x 10−19 J.
The electron moved up to an energy level and has an energy of 10.92 x 10−19 J.
The electron moved up to an energy level and has an energy of 21.72 x 10−19 J.
Answer:
The electron moved down to an energy level and has an energy of
[tex]10.92 \times 10^{-19} \textsf{J}[/tex]
Step-by-step explanation:
[tex]\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}[/tex]
[tex]\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}[/tex]
A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.
Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.
[tex]\triangle E=E_2-E_1[/tex]
[tex]\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1[/tex]
[tex]\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}[/tex]
[tex]\implies E_1= 10.92 \times 10^{-19}[/tex]

The electron moved down to an energy level and has an energy of

What’s the correct answer for the question?
Step-by-step explanation:
the dosage information bases only on age, on weight and the level of the fever. but we have no information about the fever.
so, we assume the fever is below 102.5° F.
the age is with 18 month in the valid range (0.5 to 2 years old) for the dosage.
so, all is left is to do the calculation about the weight.
24 pounds is based on the given information (1 kg ≈ 2.2 pounds) :
24/2.2 = 10.909090909... kg
this is rounded to full kg : 11 kg
the child should get 5 mg per kg, so this child has to get

convert 2FA.C8 base 16. express in Octal form, Quinary or pental form and Binary form
Using base conversion method, 2FA.C8 base 16 can be expressed as:
1372.628 in octal11022.3423120034 in pental1011111010.11001 in binaryWhat is 2FA.C8 base 16 expressed in Octal form?To express 2FA.C8 in octal form, it is first converted to a decimal form as follows:
where:
F = 15
A = 10
C = 12
2FA.C8 = 2 × 16^2 + F × 16^1 + A × 16^0 + C × 16^-1 + 8 × 16^-2
2FA.C8 = 762.7812510 in decimal.
Then, convert 762.7812510 to octal as follows:
First the integral part is converted to octal by repeated division by 8.The fractional part is converted to octal by repeated multiplication by 8 until we get to zero (here, we calculate up to ten digits)add the integral and fractional part together762 / 8 = 95 remainder 2
95 / 8 = 11 remainder 7
11 / 8 = 1 remainder 3
1 / 8 = 0 remainder 1
762 = 1372
Then;
0.78125 × 8 = 6 + 0.25
0.25 × 8 = 2 + 0
0.78125 = 0.62
Therefore, 762.78125 in decimal = 1372.628 in octal
What is 2FA.C8 base 16 expressed in pental form?To convert 2FA.C8 base 16 to pental form, we use its value in decimal for conversion.
2FA.C8 base 16 = 762.7812510 base 10Then, convert 762.7812510 to pental as follows:
First the integral part is converted to pental by repeated division by 5The fractional part is converted to pental by repeated multiplication by 5 until we get to zero (here, we calculate up to ten digits)add the integral and fractional part together762 / 5 = 152 remainder 2
152 / 5 = 30 remainder 2
30 / 5 = 6 remainder 0
6 / 5 = 1 remainder 1
1 / 5 = 0 remainder 1
762 in decimal = 11022 in pentalThen 0.78125 to pental:
0.78125 × 5 = 3 + 0.90625
0.90625 × 5 = 4 + 0.53125
0.53125 × 5 = 2 + 0.65625
0.65625 × 5 = 3 + 0.28125
0.28125 × 5 = 1 + 0.40625
0.40625 × 5 = 2 + 0.03125
0.03125 × 5 = 0 + 0.15625
0.15625 × 5 = 0 + 0.78125
0.78125 × 5 = 3 + 0.90625
0.90625 × 5 = 4 + 0.53125

190 / 2 = 95 remainder 0
95 / 2 = 47 remainder 1
47 / 2 = 23 remainder 1
23 / 2 = 11 remainder 1
11 / 2 = 5 remainder 1
5 / 2 = 2 remainder 1
2 / 2 = 1 remainder 0
1 / 2 = 0 remainder 1
762 base 10 = 1011111010 base twoThen 0.78125 to binary:
0.78125 × 2 = 1 + 0.5625
0.5625 × 2 = 1 + 0.125
0.125 × 2 = 0 + 0.25
0.25 × 2 = 0 + 0.5
0.5 × 2 = 1 + 0
