find the HCF
eg. first expression = 4a -8
=4(a-2)
​

Answer:

p is 16

Step-by-step explanation:

[tex]p \: \alpha {(q + 2)}^{2} [/tex]

introduce a constant on a right hand side:

[tex]p = k {(q + 2)}^{2} - - - eqn \: (a)[/tex]

[ when q is 1, also p is 1 ]

[tex]1 = k(1 + 2) {}^{2} \\ 1 = 9k \\ k = \frac{1}{9} [/tex]

substitute for k in eqn (a):

[tex]p = \frac{1}{9} (q + 2) {}^{2} [/tex]

so, when q is 10:

[tex]p = \frac{1}{9} (10 + 2) {}^{2} \\ \\ p = \frac{1}{9} (144) \\ \\ p = 16[/tex]

Answer:

8 minutes per customer in Restaurant One.

6 minutes per customer in Restaurant Two.

7 minutes per customer in Restaurant Three.

Restaurant Two had the fastest service.

Method:

I divided the time it took – for example – 48 divided by 6. I would do this because I wanted to find out each person took (6 people), and the amount of time it took for each person to get their food. I would use division for this problem because I am finding how much each person took out of the whole time.

Answer

The 2nd restaurant is the fastest

Step-by-step explanation:

I. Compare Time per Customers

     When 1st restuarant = 48/6 = 9

                2nd restuarant = 42/7 = 6

                3rd restuarant = 63/9 = 7

Given if in 1 min, I can serve 20 customers = 1/20 = 0.05

             in 1 min, He can serve 10 customers = 1/10 = 0.1

      See the different? I can serve better than him.

So The answer is the 2nd restuarant.

Hope that help :D

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, B to A , then

scale factor = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex] ( = 1.5 )

Answer:

-2

Step-by-step explanation:

Triangle S

Triangle L

For the base you must multiply 4 by -2 to get 2. Likewise for the height you must multiply 8 by -2 to get 4. Thus the scale factor from L to S is -2

Answer:

17x² - 22x - 2

Step-by-step explanation:

Given

(5x² + 6x - 2) + 4x(3x - 7) ← distribute parenthesis

= 5x² + 6x - 2 + 12x² - 28x ← collect like terms

= 17x² - 22x - 2

Answer:

1/8 or 12.5% probability

Step-by-step explanation:

Compound probability is what you would want to use here which is the probability of the first event multiplied by the second event.

So, if 1/4 is the probability of spinning a 1 on the spinner and 1/2 is the probability of flipping heads, you would multiply 1/4 • 1/2 to get 1/8, or 12.5%

Hi

When you have a system of equation, you generally have two unknowned value.  

The trick is to express one letter as equal of something in the second letter.

We have two lines :  

(1) :  y = -5x-1

(2) :  4x-7y = 7

Here  he job is  half done as  we have already  "y" express in " x"  with line (1)  so  :   y = -5x-1  

So I can rewrite line (2)  as this  :   4x-7y = 7

                                                         as y = -5x-1 so :

                                                          4x-7y = 7  become :

                                                           4x - 7 ( -5x-1) = 7

                                                           4x-7 * (-5x) - 7* (-1) = 7

                                                            4x +35x +7 = 7

                                                             4x +35x +7 -7 = 7-7

                                                             39x = 0

                                                                  39x/39 = 0 /39

                                                                      x = 0

So if X = 0  then we have in line (1)  we have by replacing  "x" by it's value :    y = -5x-1

y = -5*0 -1  

y =  -1

Dont hesitate to ask in comments if it's still not clear.

Answer:

The circumference is the perimeter, specifically the perimeter of a circle. It can be solved by using the following formula:  

C = 2πr

C stands for circumference.

π stands for pi, or 3.14 (rounded).

r stands for radius.

The radius is the distance from the center point of the circle to any point on the circle. It is denoted by the variable, r, as stated above. It is 1/2 of the diameter.

Answer:

the radius is the line from center to perimeter and circumference is the enclosed boundary

Step-by-step explanation:

radius- is any of the line segments from a circle or spheres center to its perimeter

circumference- the enclosed boundary a curved geometric figure, especially a circle

Answer:

x= -0.5

Step-by-step explanation:

2x-4+2x+16=10

4x+12=10

4x=-2

x=-1/2

Step-by-step explanation:

(x-2) 2 +(x+8) 2 = 10

x-2 + 2× x 2×8 + 2 = 10

x - 2 + 2x + 16 + 2 = 10

x + 2x + 16 - 2 + 2 = 10

3x + 16 = 10

3x = 10-16

3x = -6

3x÷3x = 6 ÷ 3

x = -2
