Step-by-step explanation:

Calculate the time from 9.25 pm on Monday until midnight, then add on time from midnight until 4.10 am on Tuesday, that is

9.25 pm → midnight = 2 hours 35 minutes , then

2 hours 35 minutes + 4 hours 10 minutes

= (2 + 4) + (35 + 10)

= 6 hours 45minutes

Answer:

30, +11, 11, -1

Step-by-step explanation:

-10 + 30 = 10, 40 - 30= 10

-3 + 11 = 8

5 + (1.5 x 4) = 11

5 - (1.5 x 4) = -1

Answer:

4800

Step-by-step explanation:

x is the number of total students

x * 9/20 = number of female students

x * 9/20 = 2160

Multiply each side by 20/9

x * 9/20 * 20/9 = 2160 * 20/9

x =4800

Answer:

a = 2.5, a = 0.5

Step-by-step explanation:

6a - 5 = 4a, and 6a - 5 = -4a

6a -5 = 4a

Subtract 6a from both sides

-5 = -2a

a = 2.5

6a - 5 = -4a

Subtract 6a from both sides

-5 = -10a

a = 0.5

Answer:

a=1/2 and a=5/2

Step-by-step explanation:

6a-5=4a:

Subtract 4a from both sides, ending up with 2a-5=0

Add 5 to both sides, ending up with 2a=5

Divide both sides by 2, ending up with a=5/2

6a-5=-4a

Add 4a to both sides ending up with 10a-5=0

Add 5 to both sides ending up with 10a=5

Divide both sides by 10 ending up with a=1/2

In conclusion, there are two possible solutions to the equation; 1/2 and 5/2

Answer:

a) y = [tex]\frac{1}{2} x[/tex]

b) y = [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

I. If y = 9 and x = 18

  so x is double value of y or y * 2

  y will be half of x value

 that makes y = [tex]\frac{1}{2}[/tex] x

II. If x = 5, replace x with 5

    y = [tex]\frac{1}{2}[/tex] (5)

    y = [tex]\frac{5}{2}[/tex]

Answer:

(a).

[tex]{ \boxed{ \sf{y = \frac{1}{2}x }}}[/tex]

b).

[tex]{ \boxed { \sf{y = \frac{5}{2} }}}[/tex]

Step-by-step explanation:

explanation for (a):

[tex]{ \sf{y \: \alpha \: x}} \\ { \sf{y = kx}} [/tex]

when y is 9, x is 18

[tex]{ \sf{9 = (k \times 18)}} \\ { \sf{k = \frac{1}{2} }}[/tex]

therefore equation is:

[tex]{ \sf{y = \frac{1}{2}x }}[/tex]

explanation for (b):

when x is 5:

[tex]{ \sf{y = \frac{1}{2}x }} \\ \\ { \sf{y = \frac{1}{2} \times 5}} \\ \\ { \sf{y = \frac{5}{2} }}[/tex]

Answer:

25

Step-by-step explanation:

let x = 36

y =  9

x2 = 100

y2 = y2

y : x :: y2 : x2

We know,

Product of means = Product of extremes

That is,

y(x2) = x(y2)

Substituting the values,

9(100) = 36(y2)

=> 36(y2) = 900

=> y2 = 900/36

=> y2 = 25

so when x = 100, y =25

Answer:

C. x^2 + 6x + 9

Step-by-step explanation:

(x+3)^2

using formula (a+b)^2= a^2 + 2ab + b^2,

(x)^2 + 2(x)(3) +(3)^2

=> x^2 + 6x + 9

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Table A

input is 5 and output is 9

Using the 2 given rules

Increase the input by 4 to get output , then

5 + 4 = 9 ← correct output

Multiply input by 2 and subtract 1 to get output , then

2 × 5 - 1 = 10 - 1 = 9 ← correct output

Table A works for both rules

Answer:

6, because the slope is equivalent to the value of a / 4. you see the run is 4, double of two, so the answer that makes sense is 6 as it is double of three.

Answer:

$30

Step-by-step explanation:

To find the median, arrange numbers from smallest to largest

The # of data points in this scenario are 5, which is odd.  If the # of data points is odd, the median is the data point in the center.

$28, $28, $30, $36, $40

if you wanted to find the median with an even # of data points, it's the average of the two middle data points.

The median price of the sport jerseys is : $30

Given the prices :

$28, $36, $40, $30, $28

To find the median price, we need to arrange the values in order :

Ordered prices = $28, $28, $30, $36, $40

The median formula = 1/2(n+1)th term

n = number of terms = 5

Hence,

Median price = 1/2(5 +1)th term

Median price = 1/2(6) = 3rd term

The 3rd term = $30.

Hence, the median price is $30
