Answer:

$\cos\theta=\frac{10}{\sqrt{116}}$

Step-by-step explanation:

To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.

$\cos\theta$ is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.

We can use Pythagorean's Theorem to find the hypotenuse (let $c$ represent the length of the hypotenuse):

$10^2+4^2=c^2$

$100+16=c^2$

$116=c^2$

$c=\sqrt{116}$

Thus, we know the adjacent is 10, and the hypotenuse is $\sqrt{116}$ . This means $\cos\theta=\frac{10}{\sqrt{116}}$ .

Hope this helps!

DedPeter [7]

Answer:

She needs to finish in 48.7 percent of the time it normally takes her

Step-by-step explanation:

6th grade math problem

swim 15 minutes 45 seconds

bike ride 45 minutes

She want to complete the 3 events in 70 minutes

swim + bike + run = 70

15 minutes 45 seconds + 45 minutes + run = 70 minutes

Combine like terms

60 minutes 45 seconds + run = 70 minutes

Subtract 60 minutes 45 seconds from each side

60 minutes 45 seconds - 50 minutes 45 seconds + run = 70 minutes - 60 minutes 45 seconds

run = 9 minutes 15 seconds

Her training run was 19 minutes

The percent of time she needs to take is time to finish / training run time

percent = 9 minutes 15 seconds/ 19 minutes

We need to put this in minutes. There are 60 seconds in 1 minute

9 minutes 15 seconds = 9 minutes 15/60 = 9.25 minutes

percent = 9.25 minutes / 19 minutes

percent = .486842105

percent = 48.7 percent

She needs to finish in 48.7 percent of the time it normally takes her

So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
