When you ask what 75 minutes is in decimal, we assume you want to know what 75 minutes is in terms of hours.

There are 60 minutes in an hour. Therefore, 75 minutes in decimal is 75 minutes divided by 60 minutes (75 / 60), which equals 1.25. Thus, the answer to "What is 75 minutes in decimal?" is as follows:

75 minutes = 1.25 hours


When you ask what 174 minutes is in decimal, we assume you want to know what 174 minutes is in terms of hours.

There are 60 minutes in an hour. Therefore, 174 minutes in decimal is 174 minutes divided by 60 minutes (174 / 60), which equals 2.9. Thus, the answer to "What is 174 minutes in decimal?" is as follows:

174 minutes = 2.9 hours

Answer: 6 days

Explain the steps of graphing 2x + 4≤ 12.

Answers

Answer:

Step-by-step explanation:

First, you want to simplify so the equation would be x+2≤6 or x≤4

Because you are solving for x you want to graph a vertical line on 4.

Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.

I recommend using Desmos graphing calculator.

Answers

you can use the formula of pythagoras theorem to know what of them is wrong

in the first case

-5^2 + 12^2 =169

 13^2=169         ( it's a right equation so it can be lengths of right angle tri )

in the second case

_9^2 + 12^2 =225

  17^2 not equal 225

so these are the lengths that can't be a right angle triangle

In one part of a kennel, 5/8 of the 24 dogs are male. In another part of the kennel, 4/5 of the 30 dogs are male.
How many male dogs are in the two parts of the kennel?

Answers

Answer:

39

Step-by-step explanation:

The computation of the number of male dogs in the two parts of the kennel is shown below:

In one part, the male dogs are

= 24 × 5 ÷ 8

= 15

In the another part, the male dogs are

= 30 × 4 ÷ 5

= 24

So, the total male dogs is

= 15 + 24

= 39

A third line goes through the same point. How would that show up in a table representing the relationship for the third line?

Answers

Answer:

Most likely the table will contain one pair of values that correspond to the coordinate where the previous lines intersect.

Step-by-step explanation:

It may be possible that the table before the third line contains values on either side of the point of intersection, but the slope will produce a line that connects those values and passes through the previous intersection.

The lines shown below are perpendicular. If the green line has a slope of
2/5 , what is the slope of the red line?

Answers

Answer:

-5/2

Step-by-step explanation:

for perpendicularity;

[tex]m1 = \frac{ - 1}{m2} [/tex]

where m1 is first slope

and m2 is second slope

so here, let m1 be green line slope

and m2 be red line slope

thus,

[tex]m2 = \frac{ - 1}{m1} [/tex]

[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]

[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]

Pls help with #6 pls pls!!!

Answers

Answer:

Answers in explanation.

Step-by-step explanation:

Finding angle 1:

52 + angle 1 = 180

angle 1 = 128

Finding angle 2:

128 (angle 1) + angle 2 = 180

angle 2 = 52

Finding angle 5:

52 + 47 + angle 5 = 180

angle 5 = 81

Finding angle 3:

angle 2 + angle 3 + angle 5 = 180

52 + angle 3 + 81 = 180

angle 3 = 47

Finding angle 4:

angle 3 + angle 4 = 180 OR angle 4 + 47 = 180

47 + angle 4 = 180

angle 4 = 133
