The kinetic energy, K, of an object due to its motion is given by K = mv2, where m is the mass of the object and v is its velocity. What is the mass of the object, m, in terms of its kinetic energy and velocity?
Answer:
Step-by-step explanation:
First of all, your formula isn't right. In general, the KE = 1/2 m * v^2
KE = 1/2 m * v^2 Multiply both sides by 2
2*Ke = m * v^2 Now divide by v^2
2*Ke/v^2 = m
Pablo has 7 dogs. • Pablo feeds his dogs a total of 20 pounds of dog food each week. • Pablo feeds each dog an equal amount of dog food each time he feeds them. Which statement is true? Each dog is fed between 5 and 7 pounds of dog food each week. Each dog is fed between 5 and 7 pounds of dog food each week. Each dog is fed between 4 and 5 pounds of dog food each week. Each dog is fed between 4 and 5 pounds of dog food each week. Each dog is fed between 1 and 3 pounds of dog food each week. Each dog is fed between 1 and 3 pounds of dog food each week. Each dog is fed between 0 and 1 pound of dog food each week. Each dog is fed between 0 and 1 pound of dog food each week.
Answer: I believe its the one that says "each dog is fed between 1 and 3 pounds of dog food each week"
Step-by-step explanation:
To give each dog an equal amount you'd have to divide 20 by 7.
20 / 7
when you do that is doesn't come out to a whole number
20 / 7 = 2.8571428571
anything higher than 2.8 pounds would go over his limit of 20 pounds
so true statement I think would be the one that says between 1 and 3.

Answer:
x = 15
Angle ABC = 57°
Step-by-step explanation:
Hi there!
We're given:
⇒ ABD is a straight line
⇒ Angle ABC = 5x-18 degrees
⇒ Angle DBC = 8x+3 degrees
ABD is a straight line, meaning it measures an angle of 180 degrees.
Angles ABC and DBC create line ABD, so therefore, their sum is equal to 180 degrees:
[tex](5x-18)+(8x+3)=180[/tex]
Open the parentheses:
[tex]5x-18+8x+3=180[/tex]
Combine like terms:
[tex]13x-15=180\\13x=195[/tex]
Divide both sides by 13 to isolate x:
[tex]x=15[/tex]
Therefore, x = 15.
To find angle ABC, replace x with 15 in 5x-18:
[tex]5x-18\\=5(15)-18\\=75-18\\=57[/tex]
Therefore, the measure of angle ABC is 57 degrees.
I hope this helps!

||x-2|-6|=8
Answer:
x = -12 or x = 16
Step-by-step explanation:
| x - 2 | - 6 =8
+6 +6
------------------------
| x - 2 | = 14
---> we get x = -14
---> we get x = 14
so, x = -12, or, x = 16
Subtract 45 from the sum of 243 and 6.
And a numerical expression for the calculation with parentheses
Explanation:
(243 + 6) - 45
It says add 243 and 6 so you add them together. Then it says subtract 45 from that. When it says from, you usually put the stuff your subtracting it from in parentheses.

Where would radicals come in the order of operations? Explain why.
Answer:
exponents, multiplication division addition and subtraction and radicals. They're gonna come right here with exponents on.
Step-by-step explanation:
The reason for this is because radicals, for example, X to the power or this very day vaccine is the same as X to the power of one. The humor to perhaps is the same as actually the power of 1/3. So really any radical can be expressed is an exploded as well. So this is why radicals are grouped with exponents right here. So after Grant sees in priority, but before multiplication and division
Radicals are expressions with roots (e.g. square roots, cube roots, etc.)
Radicals should be evaluated after all grouping symbols, but before any other arithmetic operators.
The grouping symbols are: brackets and parentheses
The other arithmetic operators are: addition, subtraction, division and multiplication.
Take for instance:
[tex]\mathbf{2\sqrt{4} + (5 \times 3) - 2}[/tex]
First, we evaluate the expressions in brackets
[tex]\mathbf{2\sqrt{4} + (5 \times 3) - 2 = 2\sqrt{4} + 15 - 2}[/tex]
Next, we evaluate the radical
[tex]\mathbf{2\sqrt{4} + (5 \times 3) - 2 = 2 \times 2 + 15 - 2}[/tex]
Then, we solve the remaining expressions.
