If time is four hours from now, the time left till midnight would be quarter that if it is one hour from now. What time is it now?

Answers

Answer 1

Answer:

The time now is 7 pm

Step-by-step explanation:

Suppose that now is the time T.

We know that:

"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".

Then:

if we define midnight as 12, and we assume that T is in the pm range.

Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))

With this in mind, we can write the problem as:

12 - (T + 4) = (1/4)*( 12 - (T + 1))

Now we can solve this for T.

12 - T - 4 = (1/4)*(12 - T - 1)

8 - T = (1/4)*(11 - T)

4*(8 - T) = 11 - T

32 - 4*T = 11 - T

32 - 11  = -T + 4*T

21 = 3*T

21/3 = T

7 = T

Then T = 7 pm

The time now is 7 pm

≥ means greater or equal than.

-10 is equal -10, true.

-14 is less than -10, so false.

-2 is greater than -10, true

0 is greater than -10, true

so the answer is -10, -2 and 0 can make this inequality true.

-48 ; - 16

Step-by-step explanation:

Given the expression :

X /4 = - 12

Multiply both sides by 4

X/4 * 4 = - 12 * 4

X = - 48

For the second :

X/2 = - 8

Multiply both sides by 2

X/2 * 2 = - 8 * 2

X = - 16

If a coordinate was dilated from (-3, 2) to (-6, 4), what was the scale factor used?

Answers

Given:

A coordinate pair was dilated from (-3, 2) to (-6, 4).

To find:

The scale factor.

Solution:

We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.

The value of scale factor is:

[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]

[tex]k=\dfrac{-6}{-3}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.

D

Step-by-step explanation:

Hey There!

Remember in order for the relation to be a function none of the x values can repeat

For the first one the x value 0 repeats therefore it is not a function

for the second one the x value -7 repeats thus meaning that its not a function

for the third one the x value 6 repeats hence, it is not a function

for the last one each input has a different output therefore it is a function

False

Step-by-step explanation:

Based on what is stated in the question :

Expressing the worded equation Mathematically,

(5x - 7) / 2 = y

If y = 28

(5x - 7) / 2 = 28

Cross multiply

5x - 7 = 28 * 2

5x - 7 = 56

5x = 56 + 7

5x = 63

x = 63 / 5

x = 12.6

Hence, x ≠ 9

=22+40+x

=62+x
