Write 12/7 as a mixed number.
Answer: 1 5/7
Step-by-step explanation:
Answer:
1 5/7
Step-by-step explanation:
To get a mixed number, you subtract the denominator from the numerator as many times as you can. In this case, 12 - 7 = 5, and that's all you can do. You did that once, so you get 1 whole number, and 5 seventh's left over, or 1 5/7.

Answer:
No, Yes, Yes, No
Step-by-step explanation:
The most clear aspect of right triangles is, the sum of square value of two of its legs is equal to square value of hypotenuse (the longest side)
for the first option:
10, 15, 20 : No
10^2+15^2 = 325 while the suare value of 20 is equal to 400.
we don't have to check the following values:
8,15,17 : Yes
5,12,13 : Yes
Because these are the side lengths of special right triangles according to Pythagoras
as for 4,5,6
4^2 + 5^2 = 41 while the square value of 6^2 = 36

Answer:
\(k^4+10k^2+21\)
Step-by-step explanation:
\(k^2 (k^2)\) is the same as saying \((k)(k)(k)(k)\) and so it'll be \(k^4\). Combine \(7k^{2}\) and \(3k^{2}\) by adding them both to get \(10k^{2}\). Then multiply 7 by 3 to get 21. Therefore the area of the entire rectangle written in standard form as a polynomial is \(k^4+10k^2+21\). Write the polynomial with the highest degree being first to the lowest degree and that's how you write the polynomial properly.

The price of eggs is projected to increase by 150% over the next year. A dozen eggs currently costs $1.80. What is the projected cost of a dozen eggs one year from now?
A. $2.70
B. $4.50
C. $1.90
D. $3.60
Answer:
what this means is that the price increases 50% the next year, 1/2 of 1.80 is .90 so if we want to know what the price will be next year we just add 1.80+0.90=2.70
The price of a dozen eggs next year will be 2.70
Answer:
A. $2.70
Step-by-step explanation:
So, to do this, 100% of the price of a dozen eggs and to find out what it means that it will raise to 150%, you need to start by finding what 1% is. $1.80÷100%= $0.018 (this is 1% of the price). Now, to find 150% of this, you have to multiply $0.018 by 150%.
$0.018 * 150= $2.70

Which choice when added to | −5 + 7 | will equal zero?
| +5 − 7 | [ 2] − | −5 + 7 | [3] | −( −5 + 7 ) | [4] | 7 − 5 |
i know the anwser is two but how do you get it
i need it by 5/1/23 at 8pm
Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
oints (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:
A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2.
Which statement best describes the relationship between the positions of the two players? (4 points)
a
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
b
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different.
c
Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
d
Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.
Answer: B
Explanation:
Correct way to write down co-ordinates: x,y
Dog 1's position: (-6,3)
Dog 2's position: (-6,-3)
Similarity: Both co-ordinates have -6 on the X axis (left to right line)
Difference: Dog 2's Y co-ordinate is NEGATIVE 3 while dog 1's Y co-ordinate is POSITIVE 3
The position is going to be reflected across the X axis because their X co-ordinates are the same, so dog 1 will be on the positive section for the Y axis (line that goes up and down) while Dog 2 will be on the negative section of the Y axis since it has negative 3 as its Y co-ordinate.
Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.
Answer: 37.5%
