Answer:
x = john
x + 3 = ahmad
x + (x + 3) = 63
2x + 3 = 63
2x = 60
x = 30
john is 30 so ahmad is 33

12 x^{5} y^{7} and 7 x^{2} y^{9}
Answer:
19x^7y^16
Step-by-step explanation:
And usually means to add, so combine your like terms:
12x^5y^7 + 7x^2y^9
12 + 7 = 19
x^5 + x^2 = x^7
y^7 + y^9 = y^16
Answer:
Step-by-step explanation:
(12x⁵ y⁷) * (7x²y⁹) = (12*7) * (x⁽⁵⁺²⁾ ) (y⁽⁷⁺⁹⁾)
= 84x⁷y¹⁶
In exponents multiplication, if base are same, then add the powers.
xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾

2.5 cm of snow fall on average each hour.
What is average?
The average formula is also known as the arithmetic mean, which is the ratio of the sum of all given observations to the total number of observations. Thus, using the average formula, the arithmetic mean for any sample of data can be calculated.
The average formula for a given set of data or observations can be expressed as:
Average Formula:
Average = (Sum of Observations) ÷ (Total Numbers of Observations)
Given:
The number of millimeters that fell throughout the course of the period divided by the number of hours is the mean hourly snowfall.
At 5:00 PM,
There are 4 hours from 6 PM to 9 PM.
So, there is 2 millimeters of snowfall as of 5 p.m.
and, 12 millimeters of snowfall as of 9 p.m.
Then, the accumulation of snow rises by
=12-2
= 10 cm in those four hours.
Thus, on an average the snow fall at rate
= 10/4
= 2.5
Hence, 2.5 cm of snow fall on average each hour.

u= 5i-2j+3k v= -2i+3k
Find a vector that is in the direction of the vector v , whose magnitude is twice that of vector u
9514 1404 393
Answer:
(-4√494)/13i +(6√494)/13k ≈ -6.8388i +0j +10.2585k
Step-by-step explanation:
To answer this question, you need to know two things:
1) the direction of vector v
2) the magnitude of vector u
__
direction of v
A direction is specified by a "unit vector", one with the proper ratio of components, and a magnitude of 1. It is found from a given vector by dividing that vector by its magnitude.
The unit vector in the v direction is ...
v/|v| = (-2i +3k)/(√((-2)² +3²) = (-2i +3k)/√13
__
magnitude of u
The magnitude of vector u is ...
|u| = √(5² +(-2)² +3²) = √38
__
Then the desired vector is ...
(2|u|)(v/|v|) = 2√38(-2i+3k)/√13 = (-4√494)/13i +(6√494)/13k
_____
Additional comment
We have chosen to "rationalize the denominator" by writing √(38/13) as (√494)/13.
What percentage of the total variation in test scores is not explained by the linear relationship between years of study and test scores?
Answer:
Check explanation section.
Step-by-step explanation:
So, we have the following parameters or information from the question above:
=> that the regression equation is Score = 31.55 + 10.90 Years.
So, the regression equation is in the form of mx + c.
Thus, the coefficient that is constant = 31.55 and the coefficient that shows or represents the years = 10.90.
=> Also, we have the value which is most important in this question that is the coefficient of Determination which is represented as R-sq and has the value of 83%.
The percentage of the total variation in test scores is NOT explained by the linear relationship between years of study and test scores = 100% - 83% = 17%.
For the percentage of the total variation in test scores is explained by the linear relationship between years of study and test scores = R- sq = 83%.

Yoshiro has a new puppy. She decides to create an enclosure for her puppy in her backyard. The enclosure is in the shape of a hexagon, with one pair of opposite sides running the same distance along the length of two parallel flowerbeds. A sketch of the enclosure is shown below.
QUESTION: What do you know and what do you see?
Answer:
So, I know that we will have to find the Area of the "Shape" And I see a *Unlabeled/Unknown* Shape that we have to find the answer of/to.
Step-by-step explanation:
To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet. Volume is also how loud a sound is.
To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

========================================
Explanation:
When we add matrices, we must first make sure they are the same dimensions. In this case, both are 2x3 matrices, so we can add them.
To add matrices, you add the corresponding components.
For example, in the first row, first column, we have B+A = -2+4 = 2. So the value 2 will go in the first row, first column, of the answer matrix.
The other elements are handled in a similar fashion.

Answer:
2/6 or 1/3 simplified
Step-by-step explanation:
First multiply the numerators which is the top number of both fractions, which for this equation is 1 and 2 so 1x2=2. So your final fraction would have a numerator of 2 unless simplified. Next, multiply the denominators which are the bottom numbers of the fraction for this one its 2 and 3 so 2x3=6. Your final fraction is 2/6, if simplified 1/3.

WILL RATE THE BRAINLIST Explain how you can prove your observations in question 3 using a traditional proof. You don't need to develop the steps of the proof; simply describe an approach that you might use. Which theorems might appear in your proof? (Hint: Use the two diagonals of the parallelogram to assist you in describing an approach.)
Answer:
Rectangles are parallelograms. By definition, opposite sides are congruent and all four angles have the same measure. Drawing the two diagonals of a rectangle divides the rectangle into triangles. If I choose a pair of triangles that each have a different diagonal for a side, I can prove them to be congruent. If the triangles are congruent, the corresponding sides (diagonals of the rectangle in this case) are also congruent.
