Answer:

1/9

Step-by-step explanation:

This is basically 1/3*1/3. The way you do this is multiply the top numbers together and then the bottom numbers, so 1*1=1 and 3*3= 9 so your answer is 1/9. Hope this helps you!

Answer:

$8.05(7.5)= $60.375

Step-by-step explanation:

Just multiply the two together.

I think you would round to $60.38

but 60.375 is the exact answer

Calculating the Least Common Multiple

3.1    Find the Least Common Multiple

     The left denominator is :       16

     The right denominator is :       12

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

2 4 2 4

3 0 1 1

Product of all

Prime Factors  16 12 48

     Least Common Multiple:

     48

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 3

  Right_M = L.C.M / R_Deno = 4

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      117 • 3

  ——————————————————  =   ———————

        L.C.M               48  

  R. Mult. • R. Num.      47 • 4

  ——————————————————  =   ——————

        L.C.M               48  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

117 • 3 - (47 • 4)     163

——————————————————  =  ———

        48             48

Final result :

 163          

 ——— = 3.39583

Answer:  The slope is 0

Step-by-step explanation:

The slope is the difference between the y coordinates divided by the difference between the x coordinates.

Y:  9 - 9 = 0

x: -7-2 =   -9

0/-9= 0  

Answer:

28

Step-by-step explanation:

If an area of a square is 49 units that means the length and the width are 7 units. Since a square has 4 sides that means 7*4=28. So there are 28 units.

Answer:

A: 492 km

B: 120 m

Step-by-step explanation:

Since it's a 1:x scale, just multiply it.

120 x 4.1 = 492

Then add the unit.

Same thing for B.

4 x 30 = 120.

120 m

Answer: the second function

Step-by-step explanation:

In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .

= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )

= 25 + 25 = x²

= 50 = x²

= 7.0710678119 = x

But they have given that we have to round it off to the nearest tenths , so ;

= 7.0710678119 will be equal to = 7.10

= 7.1 = x

Therefore , the length of the unknown side x = 7.1 .

Answer:

y=1/5x+12/5

Step-by-step explanation:

The slope is the same

First off there is not any choices, second off the answer is it would take

165.5 minutes

It will take the balloon 165 minutes 30 seconds to reach an altitude of 11,000

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A weather balloon is launched in Texas from an altitude of 240 feet above sea level, and the balloon rises at a constant rate of 65 feet per minute.

Let the height of the balloon is h(t) where t represents time in minutes.

∴ The function that represents the height of the balloon at any point of time is h(t) = 65t + 240.

So, time required to reach the balloon an altitude of 11,000 feet is,

11000 = 65t + 240.

65t = 11000 = 240.

65t = 10760.

t = 10760/65.

t = 165.5 minutes or 165 minutes 30 seconds.

Answer:

x = 7

Step-by-step explanation:

Given

3(2x - 9) = 15 ( divide both sides by 3 )

2x - 9 = 5 ( add 9 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Answer:

a. 13.7084 oz.

Step-by-step explanation:

Formula for Lower Control Limit =

(LCL = x-bar - A²R-bar)

x - bar = 14 oz

A2 = 0.729

R - bar = 0.4 oz

= 14 - 0.729 × 0.4

= 14 - 0.2916

= 13.7084oz
