Hello.
First, let's recall the Properties of Exponents:
[tex]\displaystyle(\frac{a}{b} )^{m}[/tex]= [tex]\displaystyle\frac{a^{m} }{b^{m}}[/tex]
Let's use this property to simplify the given expression:
[tex]\displaystyle(\frac{9}{16} )^\frac{1}{2}[/tex]
[tex]\displaystyle\frac{9^{\frac{1}{2} } }{16\x^{\frac{1}{2} } }[/tex]
Now, the [tex]\frac{1}{2}[/tex] power means "square root of"
The square root of 9 is 3, and the square root of 16 is 4.
Thus, we have
[tex]\displaystyle\frac{\sqrt{9} }{\sqrt{16} } \\\displaystyle\frac{3 }{4}[/tex]
Therefore, the answer is
[tex]\displaystyle\frac{3}{4}[/tex]
I hope it helps.
Have a nice day.

The mean for Sophia's Basketball is 8. 5 points and the mean for Valerie's Basketball games is 15. 5 points. The mean absolute deviation of both distributions is 2 points
Part A: The mean number of points scored by Valerie is 2 or 7 or 8. 5 or 15. 5 greater than the mean numbers of points scored by Sophia.
Part B: What multiple of the mean absolute deviation represents the difference in the mean number of points scored by Sophia and Valerie in the first 10 basketball games?

3. 0
3. 5
4. 0
The mean number of points scored is the average of points scored
The mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.
How to interpret the mean?The given parameters are:
Mean for Sophia's = 8.5 pointsMean for Valerie's = 15.5 points. Mean absolute deviation of both = 2 pointsCalculate the difference (d) between the mean values
d = 15.5 - 8.5
Evaluate the difference
d = 7
Hence, the mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.
The multiple of the mean absolute deviation?In (a), we have:
Mean absolute deviation of both = 2 points
Difference = 7
Express as products
Difference = 2 * 3.5
Hence, 3.5 is a factor of the difference between the mean

glue bottles did the classroom have?
Answer:
7 bottles of glue
Step-by-step explanation:
63/9= 7
every time there are 9 sticks, there is one bottle.
Answer:
7 glue bottles
Step-by-step explanation:
Ratio of glue sticks to glue bottles = 9 : 1
Therefore, 9x : 1x
If there are 63 glue sticks in total:
⇒ 9x = 63
⇒ x = 7
Therefore, glue bottles = 1x = 1 × 7 = 7

One number is 3 less than 4 times a second number. The difference of the first number and twice the second number is 7. What are the two numbers?
Answer:
x = -11, y = -2
Step-by-step explanation:
There's two equations. Let's say the first number is x, and the second number is y. Then, there is 4y-3 = x, and 2y-x = 7. We plug in 4y-3 for x into the second equation, and we get 2y - (4y-3) = 7. Solving more gets us -2y + 3 = 7. thus, -2y = 4, meaning y = -2. We plug back into the second equation, getting -4 - x = 7. This 11 = -x, or x = -11.
A bicycle store cost 4500$ per month to operate. The store pays an average of 35$ per bike. The average selling price of each bike is 125$.How many bicycles must the store sell each month to break even
Answer:

Find x
Answer:
x=-2
Step-by-step explanation:
[tex]14+5x=3\left(-x+3\right)-11[/tex]
[tex]3\left(-x+3\right)-11[/tex] ← ( Expand)
[tex]14+5x=-3x-2[/tex]
[tex]14+5x-14=-3x-2-14[/tex] ← ( Subtract 14 from both sides)
[tex]5x=-3x-16[/tex]
[tex]5x+3x=-3x-16+3x[/tex]
[tex]8x=-16[/tex]
[tex]\cfrac{8x}{8}=\cfrac{-16}{8}[/tex] ← ( Divide both sides by 8)
[tex]x=-2[/tex]
~
Answer:
-2Step-by-step explanation:
In the question we have given with an equation that is 14 + 5x = 3 ( -x + 3 ) - 11 .
And we are asked to find the value of x.
Solution : -
[tex] \longmapsto \: 14 + 5x = 3( - x + 3) - 11[/tex]
Step 1 : Solving parenthesis on right side :
[tex] \longmapsto \: 14 + 5x = - 3x + 9 - 11[/tex]
On further calculations we get :
[tex] \longmapsto \: 14 + 5x = - 3x - 2[/tex]
Step 2 :
Subtracting 14 from both sides :
[tex] \longmapsto \: \cancel{14} - \cancel{14 }+ 5x = -3x -2 - 14[/tex]
On further calculations we get :
[tex] \longmapsto \: 5x = - 3x - 16[/tex]
Step 3 : Adding 3x on both sides :
[tex] \longmapsto \: 5x + 3x = - \cancel{ 3x} + \cancel{3x} - 16[/tex]
On further calculations we get :
[tex] \longmapsto \: 8x = - 16[/tex]
Step 4 : Dividing by 8 on both sides :
[tex] \longmapsto \: \frac{ \cancel{8}x}{ \cancel{8}} = \cancel {\frac{ - 16}{8} }[/tex]
We get :
[tex] \longmapsto \: \red{\boxed{ \mathfrak{x = - 2}}}[/tex]
Therefore , value of x is -2 .Verifying :We're verifying our answer by substituting value of x in given equation . So ,
14 + 5x = 3 ( -x + 3 ) - 11 14 + 5 ( - 2 ) = 3 { -( -2 ) + 3 ) - 1114 - 10 = 3 ( 2 + 3 ) - 11 4 = 3 ( 5 ) - 114 = 15 - 114 = 4L.H.S = R.H.SHence , Verified .Therefore , our value for x is valid .

A. 44/8
B. 5 1/2
C. 5 1/5
D. 5.500
Answer:
C. 5 1/5
Step-by-step explanation:
A, B, and D are all 5.5 and C alone is 5.2
Answer:
C is the odd one.Step-by-step explanation:
Let's verify each option.
Option A
44/8 = 40/8 + 4/8 = 5 1/2 = 5 + 0.5 = 5.5Option B
5 1/2 = 5 + 0.5 = 5.5Option C
5 1/5 = 5 + 0.2 = 5.2Option D
5.500 = 5.5Looking at the options, we can see that the result of Option A, B, and D are same.
This means that the odd one is Option C.
x + y = 95. and y is 2/3 of x. find x and y.
Answer:
{x,y}={60,35}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = y + 25
// Plug this in for variable x in equation [1]
[1] (y +25) + y = 95
[1] 2y = 70
// Solve equation [1] for the variable y
[1] 2y = 70
[1] y = 35
// By now we know this much :
x = y+25
y = 35
// Use the y value to solve for x
x = (35)+25 = 60
Answer:
x=57
y=38
Step-by-step explanation:
(1): x+y=95
(2): y=2/3x
substitute y=(2/3)x in equation (1):
x+(2/3)x=95
Multiply both sides by 3
3x+2x=285
5x=285
Divide both sides by 5
x=285/5
x=57
substitute x=57 in equation (2):
y=2/3×57=38
hence: x=57 , y=38

The spinner has 3 equal sections for each color: green, purple, and orange.
What is the probability of landing on a color other than green?
Enter your answer as a fraction, like this: 42/53
Answer:
2/3
Step-by-step explanation:
so, you have a circle and if you divide it into 3 equal sections each of those sections take only 1/3 of the circle.
1/3 + 1/3 + 1/3 = 1
if one of the thirds is green then the probability of it landing on another color would be 2/3 being the other two colors.
