Colin put a pie in the oven at 1:35 p. M. He took the pie out at 2:17 p. M. How long was the pie in the oven?
bulgar [2K]

Answer:

42 minutes

Step-by-step explanation:

there are 60 minutes in one hour.

from 12 pm, 1 hour and 35 minutes have passed to get to 1:35 pm

from 12 pm, 2 hours and 17 minutes have passed to get to 2:17 pm

we are trying to figure out the start to end time, or the difference between the times

2 hours and 17 minutes - 1 hour and 35 minutes

1 hour = 60 minutes

if we convert everything to minutes we can get a definitive time in one single unit

2 hours = 1 hour * 2 = 60 minutes * 2 = 120 minutes

1 hour = 60 minutes

plug these in

(120 + 17) minutes - (60 + 35) minutes

= 137 minutes - 95 minutes

= 42 minutes as our answer

Point Find the length of segment CD with C(2,3) and D (-3, 15​
gladu [14]

Step-by-step explanation:

so, if the text is correct, the 2 points are

(2, 3) and (-3, 15).

the length of the line segment is the distance between both points.

did this we use Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.

so,

distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169

distance = sqrt(169) = 13 = length of line segment

3x to the power of two minus x<br> Factor by gcf
algol13

Answer:

After factorizing the given expression we get the value as x(3x-1).

Step-by-step explanation:

Given:

3x^2-x

We need to factorize the given expression using GCF.

Solution:

3x^2-x

Now GCF means Greatest common factor.

From the given 2 numbers we need to find the greatest common factor.

3\times x\times x- 1 \times x

In the given expression GCF is 'x'.

Hence we can say that;

x(3x-1)

Hence After factorizing the given expression we get the value as x(3x-1).
