Answer:
7
Step-by-step explanation:
A square has 4 sides, all of equal length. We can simply find the square root of the area to find the length and width, or length of each side. So to find the length, you find the square root of the area.

Factorize -6m plus 9
Answer:
[tex]3(-2m + 3)[/tex]
Step-by-step explanation:
Given
[tex]-6m + 9[/tex]
Required
Factorize
Expression: [tex]-6m + 9[/tex]
Start by expressing the expression as a sum of products.
[tex]-6m = 3 * -2m[/tex] and
[tex]9 = 3 * 3[/tex]
So;
[tex]3 * -2m + 3 * 3[/tex]
Notice that constant 3 is common in both terms.
This can then be factorizes as:
[tex]3(-2m + 3)[/tex]
Hence:
[tex]-6m + 9 = 3(-2m + 3)[/tex]
Answer:
3(-2m+3)

Blake is working two summer jobs, making $9 per hour washing cars and making $22 per hour tutoring. In a given week, he can work no more than 16 total hours and must earn no less than $220. If x represents the number of hours washing cars and y represents the number of hours tutoring, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
9x + 22y ≥ 220
x + y ≤ 16
Step-by-step explanation:
First x is number of hours washing cars and y is number of hours tutoring.
He makes $9 per hour on cars, $22 per hour tutoring. So we use variables as substitutes for actual values.
That is 9x + 22y. He can't make less than 220, so use the sign greater or equal to 220.
He also must work no more than 16 hours. Total hours is x+y, and no more than 16 means use the sign less than or equal to.

The number of hours washing cars and number of hours tutoring, if Blake is working two summer jobs, making $9 per hour washing cars, making $22 per hour tutoring, are 10.2 and 5.85 respectively. The graph is also attached below.
What is equation?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in, 3x + 5 Equals 15, instances.
Given:
Blake is working two summer jobs, making $9 per hour washing cars, making $22 per hour tutoring,
Total working hour = 16
Total money to be earned = $220
Write the equation of the above statement as shown below,
x + y = 16
9x + 22y = 220
Solve the above equation using a graph,
y = 5.85 and x = 16 - 5.85 = 10.2

The diagonals of square LMNP intersect at K. Given that LK = 1, find the measure of MP.
Answer: MP = 2
========================================================
Work Shown:
LK = 1 is given
LK = KN since the diagonals of a parallelogram bisect one another. The same can be said about PK = KM.
Since all squares are a rectangle, this means LN = MP. Any rectangle has its diagonals be congruent.
So,
LN = LK+KN
LN = 1+1
LN = 2
MP = LN
MP = 2

❀ Explanation :
✑ Let's Know about A.M ( Arithmetic Mean )
In statistics , a single number can be calculated from a group of data which shows the character of the whole data. This number is called the average of the while data. An average is also called the arithmethic mean or simply mean which is a measure of central tendency.
☄ To calculate the average of the given type of data ( discrete series ) , follow the steps given below :
Make the table of 3 columns .Write down the items or observations ( x ) in the first column in ascending order and the corresponding frequency ( f ) in the second column.Multiply the data ( x ) by their corresponding frequency ( f ) and write down the product in third column of fx.Find the sum of f - column and fx - column separately.Divide the sum of fx by the sum of f , the quotient so obtained is the required mean.✐ Remember :
[tex] \underline{ \boxed{ \sf{mean \: = \frac{Σfx}{Σf} \: or \: \frac{Σfx}{n}}}} [/tex]
Where , Σf = N = Sum of the frequency and the symbol ' Σ ' ( sigma ) means " summation of " .

Answer:
The answer is B.
Step-by-step explanation:
Let us first set up an equation.
(3x - 7) + (2x + 3) = 90
5x - 4 = 90
5x = 94
x = 18.8
Hope this helps!
Please mark as brainliest.
Answer:
D m<A = 49.4 deg
Step-by-step explanation:
Since the lines are perpendicular, the sum of the measures of angles A and B is 90 deg.
m<A + m<B = 90
3x - 7 + 2x + 3 = 90
5x - 4 = 90
5x = 94
x = 18.8
m<A = 3x - 7 = 3(18.8) - 7 = 56.4 - 7 = 49.4
Answer: D m<A = 49.4 deg
a conical tank with vertex down is 10 feet across the top and 12 feet deep. If water is flowing out of the tank at a rate of 12 cubic feet per minute, find the rate at which the water level is dropping when radius of water level is 4ft.
Answer:
The water level is dropping at a rate of 0.24 ft/s
Step-by-step explanation:
Here, we simply want to calculate the change in depth (height of the cone) , given the volume change
Mathematically, we have the volume of a cone as;
V = 1/3 * π * r^2 * h
we are given dv/dt as 12 ft^3/m
dv/dh = 1/3 * π * r^2
Substituting the value for the radius, we have
dv/dh = 1/3 * 22/7 * 4^2 = 50.29
dh/dt = dh/dv * dv/dt
dh/dv = 1/(dv/dh) = 1/50.29
Thus,
dh/dt = 1/50.29 * 12
dh/dt = 0.24 ft/s
6x - 7 = 11 show the step as well please
Answer:
x = 3
Step-by-step explanation:
6x - 7 = 11
First, add 7 to 11 which gets you 6x = 18
Then, divide 18 by 6 to solve for x which gets you 3
This means that x = 3
(hope this helps)
Answer:
Step-by-step explanation:
6x-7+11
(add 7 to both sides, canceling out the negative 7 on the left, and resulting in a sum of 18 on the right)
6x=18
(divide both sides by 6, which should isolate x because the sixes will cancel each other out, and give you a quotient of 3 on the right side)
x=3

If you have two 6-sided dice, each with the numbers 1-6 on a side, what is the theoretical probability of rolling 3 and 3 when both die are rolled together?
Answer:
The probability is 1/36
Step-by-step explanation:
Since we have two dies rolled together, the sample space is 36
What we mean by the sample space is the number of total possible results
So the total number of results that we can get is 36
Out of all our result, 3,3 can only appear once
so the probability of getting 3,3 on both dice is 1/36
Answer:
1/36

There are 27 students in Mrs. Augello’s math class. The number of boys is three less than the number of girls. Write a system of equations that represents the number of boys and girls.
Answer:
x + y = 27
y = x - 3
Step-by-step explanation:
x = # of girls
y = # of boys
first there are a total of 27 students so # of girls plus # of boys has to be 27.
then number of boys is 3 less than number of girls. This means x - 3 = y or y = x-3
