If PQRS is a kite, find m angle Q
Answer:
Q = 35
Step-by-step explanation:
1. You add both (m)x values and y values making them equal to 180 creating a 2 step-equation: (7x+2) + (10x-31) making that 17x-33= 180
2. Now you have a 2 step-equation to solve: 17x-33 = 180-33=147
+-33 +-33
__________
17x = 147/17=21
/17 /17
3. From here with 21, knowing the kite must equal to 180, you add 21 to the other angle 124: 124+21=145
4. Seeing that you don't have a total of 180, you now subtract 145 from 180 in order to get the value of Q: 180-145= 35
Q= 35
Step-by-step explanation:
7x + 2 = 10x - 31
33 = 3x
x = 11
so, 7x + 2 = 7( 11 ) +2 = 79°
10x - 31 = 10( 11 ) - 31 = 79°
ΔP + ΔQ + ΔR + ΔS = 360°
79° + ΔQ + 79° + 124° = 360°
ΔQ + 282° = 360°
ΔQ = 360° - 282°
ΔQ = 78°

$73 is what percent of $125
Answer: The question $73 out of 125 is 58.40%
Step-by-step explanation:
$73 out of 125 is what percent Answer: The question $73 out of 125 is 58.40%, which is the same as 73/125 as a percent. This can be solved using this calculator above
The $73 is approximately 58.4% of $125.
To find what percent $73 is of $125, we can use the following formula:
Percent = (Part / Whole) * 100
In this case, $73 is the part and $125 is the whole.
Substituting these values into the formula:
Percent = (73 / 125) * 100
Dividing 73 by 125:
Percent = 0.584 * 100
Multiplying 0.584 by 100:
Percent = 58.4
Therefore, $73 is approximately 58.4% of $125.

Answer:
12x= 180
Step-by-step explanation:
The sum of a triangle always adds up to 180 so,
(4x-1)+ (2x-1) +6 = 180
12x=180
x=15
Answer:
The equation you could use is the 3rd solution. You need to add all of the nubers that have an x after it because you can't add a number that doesn't have x and a number that does have x. So once you add all of those, you add the 10, and keep the subtrction symbol instead of the addition symbol. And like I said before, all triangles are equal to 180.

0.98
0.925
0.88
0.7
The descending values of the numbers is 0.98 > 0.925 > 0.88 > 0.7
Given data ,
Let the numbers be represented as A
Now , the value of A is
A = { 0.98 , 0.925 , 0.88 , 0.7 }
And , arranging in the descending order means from the greatest to the least value
So , the value of A is 0.98 > 0.925 > 0.88 > 0.7
Hence , the descending order is 0.98 > 0.925 > 0.88 > 0.7

To find:
The simplified form of given expression.
Solution:
We have,
[tex]\dfrac{e\times e\times e\times f}{e\times e\times f\times f}[/tex]
The common factors in numerator and denominator are e, e, f.
Cancel out the common factors.
[tex]=\dfrac{e}{f}[/tex]
Therefore, the required expression is [tex]\dfrac{e}{f}[/tex].
One supermarket sold 72 cases of Zing soap, but only one-third as many cases of Essence soap. If each case holds 156 bars of soap, how many bars were sold in all
There will be 1334 bars sold in all if each case holds 156 bars of soap.
From the question, we are told that one supermarket sold 72 cases of Zing soap, if there is only one-third as many cases of Essence soap, then;
Amount of cases of Essence soap = one-third of 72
Amount of cases of Essence soap = [tex]\frac{1}{3} \times 72[/tex]
Amount of cases of Essence soap = 24cases
If each case holds 156 bars of soap, then we can write:
1 case = 56 bars of soap
To get the total bars that were sold. we can write:
24cases = x
DIvide both expressions:
[tex]\frac{1}{24} = \frac{56}{x} \\cross \ multiply\\1 \times x=24 \times 56\\x=1334 bars[/tex]
This shows that 1334 bars were sold in all

WWhat is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Triangle A prime B prime C prime has points (3.7, 6), (2, 5.4), (3, 1). x = 3 y = 3 y = x x = 6
Answer:
[tex]y = x[/tex]
Step-by-step explanation:
Given
[tex]A =(6,3.7)[/tex]
[tex]B = (5.4,2)[/tex]
[tex]C = (1,3)[/tex]
[tex]A' = (3.7, 6)[/tex]
[tex]B' = (2, 5.4)[/tex]
[tex]C' = (3, 1)[/tex]
Required
The equation for the line of reflection
Taking points A and A' as a point of reference:
[tex]A =(6,3.7)[/tex] and [tex]A' = (3.7, 6)[/tex]
First, calculate the midpoint (M)
[tex]M = (\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})[/tex]
[tex]M = (\frac{3.7+6}{2},\frac{6+3.7}{2})[/tex]
[tex]M = (\frac{9.7}{2},\frac{9.7}{2})[/tex]
[tex]M = (4.85, 4.85)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{6 - 3.7}{3.7 - 6}[/tex]
[tex]m = \frac{2.3}{-2.3}[/tex]
[tex]m = -1[/tex]
The midpoint of a reflection is always perpendicular to the points being reflected.
So, the slope of [tex]M = (4.85, 4.85)[/tex] is:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{-1}[/tex]
[tex]m_2 = 1[/tex]
The equation is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex](x_1,y_1) = (4.85,4.85)[/tex]
[tex]y = 1(x - 4.85) + 4.85[/tex]
[tex]y = x - 4.85 + 4.85[/tex]
[tex]y = x[/tex]
Hence, the equation of line of reflection is:
[tex]y = x[/tex]

Work out length AB.
Answer:
23.41cm
Step-by-step explanation:
Using Pythagoras theorem
a²+b² = c²
Where a and b are sides of the triangle and c is the Hypotenuse.
If we substitute the values
B= 8 cm
A= 22 cm
22²+8² = c²
484 + 64= c²
√548 = c
C= 23.41
Hence, length AB is 23.41cm

percent change in student enrollment?
Answer:
13% decrease. (13.4193548...% to be specific)
Step-by-step explanation:
The difference is 1550-1342=208. 208 as a percentage of 1550 --> 208/1550= 0.134193548... = 13% to the nearest whole number. So, it is a 13% decrease.
