Answer:
We do this by dividing 360° by the size of one exterior angle, which is 72°. The answer is 360° ÷ 72° = 5 sides. to see whether you are correct.

how do you multiply powers that have the same base
Answer:
The exponent "product rule" tells us that, when multiplying two powers that have the same base you can add the exponents in this example you can see how it works. Adding the exponents Is just a short cut! the "power rule" tells us that raise power to a power, just multiply the exponents
What is the answer to 5+(x−2)=−8
Answer:
x= -11
Step-by-step explanation:
Use Math way.
find the length of the missing side
Answer: x=12
Step-by-step explanation:
20 squared= 400 and 16 squared= 256. The Protagorean Theorm is a sqaured plus b sqaured equals c squared. You just reverse the Theorm to C sqaured minus B squared= A squared. 400-256=144 (12x12= 144)

Your weld settings are 17.5 volts and 125 amps. use ohm's law to count how much resistance is in your welding circuit.
Answer:
0.14 ohmsStep-by-step explanation:
We know that ohms law is given by the expression
V=IR
In the problem, we are given that
voltage v= 17.5volts
currents I=125 amps
Substituting our data into the expression we have
17.5=125*R
R=17.5/125
R=0.14 ohms
Hence the current is 0.14 ohms
Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width of one-half millimeter, and height of start fraction 3 over 8 end fraction millimeter. The volume is $$ cubic millimeter.
Answer:
The volume of the rectangular prism is 3/20 (or 0.15) mm³.
Step-by-step explanation:
The volume of the rectangular prism can be calculated as follows:
[tex] V = l*w*h [/tex] (1)
Where:
l: is the length = 4/5 mm
w: is the width = 1/2 mm
h: is the height = 3/8 mm
By entering the values of l, w, and h into equation (1) we can find the volume:
[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]
Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.
I hope it helps you!
What is the equation of a quadratic function that has zeros -6 and -2?
Answer:
[tex]y=x^{2} +8x+12[/tex] is the quadratic function.
Step-by-step explanation:
We know that -6 and -2 are the zeros. So, they are both equal to x.
x = -6 and x = -2
Add them to x.
(x + 6) (x + 2)
Now, multiply the two binomials together.
[tex]x^{2} +6x+8x+12[/tex]
Combine like terms.
[tex]y=x^{2} +8x+12[/tex]
[tex]y=x^{2} +8x+12[/tex] is the answer.
Let A be the event that there are at least two fives among the four rolls. Let B be the event that there is at most one five among the four rolls. Find the probabilities P(A) and P(B) by finding the ratio of the number of favorable outcomes to the total (i.e., P(A) = #A #Ω and P(B) = #B #Ω ).
Answer:
P(A) = 31/1296
P(B) = 125/1296
Step-by-step explanation:
Here, we want to find P(A) and P(B)
Let’s start with A
In a roll of a die, the probability that there will be a 5 is 1/6
The probability of not having a 5 is therefore 1-1/6 = 5/6
So out of four rolls , we want to find the probability of having at least two fives
This means there could be 2, 3 or 4 fives;
For two fives;
We have 2 fives and two non-fives
= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296
For 3 fives;
we have 3 fives and 1 non five
= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296
For 4 fives;
= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296
So the probability of at least two fives is;
1/1296 + 5/1296 + 25/1296 = 31/1296
Event B is the probability that there is at most one five among the four rolls
That means there are 3 non fives and 1 five
P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296
Which equation is true when the value of x is -12
Answer:
Which equation is true when the value of x is -12 HERE YOU GO!!
Step-by-step explanation:
tricky ... let's see ...
I notice that if we subtract xy from both sides we get
7x + xy - xy = xy - xy + 21
then
7x = 21
and
x = 21/7 = 3
so there is only one value of x that satisfies the equation
x = 3
Going back to the original equation we see that any value of y will satisfy the original equation
we can see this by rearranging things:
7x + xy - xy = 21
here, I have performed the subtraction of xy on the right side as above, but have left the left side undone
(so we don't lose the presence of y)
Note that the above can also be written as
7x + (x - x)y = 21
or
7x + 0y =21
now, since anything times zero equals zero,
y may be any number.
Let's summarize:
1) x = 3
2) y = anything
looking back at the original question;
1) the equation is true for all ordered pairs
FALSE (only one x works, not all x)
2) there are no x and y pairs for which the equation is true.
FALSE (x=3, y=anything) makes it true, i.e. (3,1)
3) For each value of x, there is one and only one value of y that makes the equation true,
FALSE for each value of x, for the one value of x, x=3, y can be any number, which is an infinite number, not one
4) for each value of y, there is one and only on value of x that makes the equation true.
TRUE!! for all the infinite values of y you may pick, there is one and only one x you may pick, x = 3

4. Is the expression (10x + 5 - 6x - 2) equivalent to (5x + 1 - (x - 2))? [True or False]
Prove this using algebra - Show work].
Answer:
true
Step-by-step explanation:
this is because
(10x+5-6x-2)
(10x-6x)+(5-2)
which equals 4x+3
then
(5x + 1 - (x - 2))
5x+1−x+2
(5x−x)+(1+2)
also equals
4x+3

The complete question is shown on the first uploaded image
Answer:
The expression are
[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]
and
[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]
Step-by-step explanation:
Generally from the diagram the energy change from state A to state B is
[tex].\ \ \Delta E_2 \ \ \ \ \ \ \ \ \Delta E_2 \\A \ \ \to \ \ \ C \ \ \ \to \ \ \ B\\[/tex]
Also
[tex].\ \ \Delta E_3 \ \ \ \ \ \ \ \ \Delta E_4 \\A \ \ \to \ \ \ D \ \ \ \to \ \ \ B\\[/tex]
So two expressions for the difference in internal energy between state a and state b are
[tex]\Delta E = \Delta E _1 + \Delta E_2[/tex]
and
[tex]\Delta E = \Delta E _3 + \Delta E_4[/tex]

Brett has consumed 1,400 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 2,000 calories per day. How many calories does he have left to consume for the day? Is 1,200 a viable solution to this problem?
I NEEED HELPP PLZZ :(
A Yes; 1,200 is less than 1,400.
B Yes; 1,200 is less than 2,000.
C No; 1,200 is more than the 400 he burned off at the gym.
D No; 1,200 will cause him to exceed 2,000.
Answer
D
Step-by-step explanation:
D is correct because 1,400-400= 1,000
so he can only consume 1,000 more calories so 1,200 will cause him to go over 2,000
