Answer:

Option C.

Step-by-step explanation:

Kurt started for the school at 07:35 and ends at 08:25.

Time taken by Kurt to reach the school

= 08:25 - 07:35

= (07 hours + 85 minutes) - (07 hours + 35 minutes) [Since 08 hours + 25 minutes = 07 hours + (60 + 25)minutes]

= 85 minutes - 35 minutes

= 50 minutes

Time taken by Drew to reach the school

= 08:30 - 07:55

= (07 hours + 90 minutes) - (07 hours + 55 minutes) [Since 08 hours + 30 minutes = 07 hours + (60 + 30)minutes]

= 90 minutes - 55 minutes

= 35 minutes

Difference in the time taken by Kurt and Drew = 50 - 35 = 15 minutes.

Therefore, Drew is 15 minutes faster than Kurt.

Option C. is the answer.

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.

Andrew [12]

Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as $\frac{y_2-y_1}{x_2-x_1}$ . Plugging in the following values would provide you with:

$\frac{(r)-(-5)}{(5)-(2)} =2$

$\frac{r + 5}{3} = 2$

$r + 5 = 6$

$r = 1$

Hope it helps :) and let me know if you want me to elaborate on anything.

Which is true? A 0.9919 > 0.999 B 1.4359 < 1.446 C 2.6953 = 2.75 D 4. 9395 > 5.0

Leona [35]

Option B. is true.

A isn't true because 0.9919 is lesser than 0.999.
C is false because 2.6953 is lesser than 2.75. They are not equal.
D is also false because 4.9395 is not greater than 5.0.

Answer:

B. 1.4359 < 1.446

Hope you could get an idea from here.

Please help me on questions 16 and 17 and please explain it thanks

Yuliya22 [10]

We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.

distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A

_____
There is no question 17.

_____
15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.

Whats 2/5 times 6/7 simplified

hichkok12 [17]

In order to multiply fractions, we multiply the two numerators together, and multiply the two denominators together.

$\frac{2}{5}\times \frac{6}{7} =\frac{2\times6}{5\times7} \\\frac{2\times6}{5\times7} =\frac{12}{35}$

12/35 is the answer
