Answer:
x + (x +3) + (x +7) = 37
3x = 27
x = 9
Longest side = x + 7 = 16 cm
Step-by-step explanation:
Answer:
16cm
Step-by-step explanation:
x + x + 3 + x + 7 = 37 (make all sides equal 37)
3x + 10 = 37 (Add x's and coefficiants together)
-10 -10 (subtract 10 from each side)
3x = 27 (divide 27 by 3)
x = 9 (answer)
x, x + 3, x + 7 (finding longest length)
9, 9 + 3, 9 + 7 (Substitute 9 for x)
9cm, 12cm, 16cm (add each together)
16cm (answer)
Overall, divorce rates have declined in the last 20 years, but among middle-aged couples, the rates are rising. Do an internet search to find what current statistics are available for different groups of individuals, then describe three factors that contribute to contemporary rises in middle-aged divorce rates.
Answer:
The current divorce rate is about 7% based on the survey.
Step-by-step explanation:
The divorces occur when two person fails to accept each other as a life partner. In the country the divorce rate is about 7% of which mostly couples are at the age of 20 - 25. The people of age 30 plus are less likely to get divorced as they have matured mind sets which accepts each other differences and tries to adjust the situation.
Divorce describes a form of marital separation which is usually undertaken by a court. It occurs when one or both partners decide to quit being married.
The middle age divorce rate continues to rise, as it is being reported in various channels. Currently the middle age divorce rate stands at about 17% per 1000 married person.The causes of rising divorce rates among middle - aged may include :
Rising cases of infidelity as spouses continue to find it difficult to be committed in marrige. Sacrifices which helps foster lasting partnership can no longer be undertaken.
Also, the need to be independent as taken over at this time, as partners begin to see marriage as a bond age which prevents or curtails them from what they would love to indulge in.

A system of equations is graphed on the grid.
Which system of equations does the graph represent?
Answer:
y = x + 4
y = -2x - 4
Step-by-step explanation:
Since equation of the line having slope 'm' and y-intercept 'b' is given by,
y = mx + b
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of line passing through (1, 5) and (-1, 3),
m = [tex]\frac{5-3}{1+1}[/tex] = 1
y-intercept 'b' = 4
Therefore, equation of the line is,
y = 1.x + 4
y = x + 4
Now slope of another line passing through (-4, 4) and (-1, -2) will be,
m = [tex]\frac{4+2}{-4+1}[/tex]
m = -2
y-intercept 'b' of this line = -4
Equation of the other line,
y = (-2)x - 4
y = -2x - 4
Therefore, system of equations is,
y = x + 4
y = -2x - 4
The system of equations is given by: y = x + 4 and y = -2x - 4
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
The first line passes through point (-1, 3) and (1, 5) hence:
[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{5-3}{1-(-1)} (x-(-1))\\\\y=x+4[/tex]
The second line passes through point (-4, 4) and (-1, -2) hence:
[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4=\frac{-2-4}{-1-(-4)} (x-(-4))\\\\y=-2x-4[/tex]
The system of equations is given by: y = x + 4 and y = -2x - 4

Answer:
x = 168.75°
Step-by-step explanation:
Angle Measurement Units
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:
[tex]\displaystyle x=\frac{15}{16}\pi[/tex]
Multiplying by 180/π:
[tex]\displaystyle x=\frac{15}{16}\pi\cdot \frac{180}{\pi}[/tex]
Simplifying:
[tex]\displaystyle x=\frac{15*180}{16}[/tex]
x = 168.75°

Step-by-step explanation:
Raju and Ann saved a total of $1560. After Raju gave Ann $50, Raju had 5 times as much money as Ann. How much did Raju have at first?
Step-by-step explanation:
let amt of money Raju has be r and Ann be a.
a + r = 1560
a = 1560 - r --(1)
r - 50 = 5(a + 50)
r = 5a + 300 --(2)
sub (1) into (2):
r = 5(1560 - r) + 300
r = 8100 - 5r
6r = 8100
r = 1350
therefore he has $1350 at first.

What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.
We have,
Let the amount of money Raju = R
Let the amount of money Ann = A
Now,
Raju and Ann saved a total of $1560.
This statement can be written as:
R + A = 1560 ____(1)
After Raju gave Ann $50, Raju had 5 times as much money as Ann.
This statement can be written as:
R - 50 = 5 ( A + 50 )
R - 50 = 5A + 250
R - 5A = 250 + 50
R - 5A = 300 _____(2)
From (1)
R = 1560 - A _____(3)
Putting (3) in (2),
1560 - A - 5A = 300
1560 - 6A = 300
1560 - 300 = 6A
1360 = 6A
A = 1260 / 6
A = 210
Putting A = 210 in (3) we get,
R = 1560 - A
R = 1560 - 210
R = 1350
Thus the amount of money Ann has at first is $1350.

You are rolling one die. Let event A = rolling a six and let event B = rolling a number less than
four. What is the probability of A or B?
Answer:
2/3
Step-by-step explanation:
A = rolling a six
B = rolling a number less than 4
Probability of A or B
P(A) or P(B) = P(A) + P(B) - P(AnB)
Probability = (number of required outcome / Total possible outcomes)
P(A) = 1 / 6
P(B) :
Required outcomes = (3, 2, 1) = 3
P(B) = 3/6 = 1/2
P(AnB) = A={6} ; B = {1,2,3} ; AnB = {}
P(AnB) = 0
Hence,
P(A) or P(B) = 1/6 + 1/2 - 0
= (1 + 3) / 6
= 4/ 6
= 2/3

Find the Unit Rate: If 12 50.7 FI. Oz. bottles cost $84 how much does one bottle cost? Find the init Rate.
Your statement is a little ambiguous due to type mistake, so I am assuming you meant to say:
'if 12 fl. oz. bottles cost $84 how much does one bottle cost? Find the Unit Rate.
so I am solving based on '12 fl. oz.' bottles costing $84.
Answer:
unit rate = 7 $ per fl. oz.
Therefore, the 7 $ per fl. oz is the unit rate.
Step-by-step explanation:
We know that a unit rate is basically a fraction (also called ratio) between two different units with a denominator of 1.
For example, kilometers per hour, and heartbeats per minute, etc.
Here, I assume, by 'unit rate' means you mean to say 'cost per fl. oz.'
Given
The cost of 12 fl. oz. bottlers = cost $84
The cost of 1 bottle cost = $84 ÷ 12 oz = 7 $ per fl. oz.
Hence,
unit rate = 7 $ per fl. oz.
Therefore, the 7 $ per fl. oz is the unit rate.
Which of the following best describes the graph above?
A. Function only
B. Relation only
C. Both relation and function
D. Neither relation nor a function
Answer: C
Step-by-step explanation:
We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.
So, basically, if a graph is a function, it is a relation as well.
Let’s check if this is a function.
We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function
In our case, it passes the vertical line test.
Therefore, it is both a function and a relation, which corresponds to letter C.

A 48 ft rope is cut into 5 pieces according to the
ratio 2:2:3:4:5. What is the length. In feet, of the
longest piece?
A. 3
B. 6
C. 9
D. 15
please Answer ASAP
Answer:I think it d
Step-by-step explanation:
The length of the longest piece will be 15 ft.
We have a 48 ft rope is cut into 5 pieces according to the ratio →
2 : 2 : 3 : 4 : 5.
We have to determine the length in feet of the longest piece.
A rope of length 'y' ft is cut in the ratio 2:5. What is the length of smallest piece?Now -
2x + 5x = y
x = [tex]$\frac{y}{7}[/tex]
Smallest piece is of length → 2x → [tex]$\frac{2y}{7}[/tex]
According to the question, we have -
Length of rope = 48 ft
Ratio in which they are cut = 2 : 2 : 3 : 4 : 5.
Therefore -
2x + 2x + 3x + 4x + 5x = 48
16x = 48
x = 3
Length of the longest piece = 5x = 5 x 3 = 15ft
Hence, the length of the longest piece will be 15 ft.
