If it takes a sloth 10 minutes to climb 7.5 feet what’s its climbing speed in miles per hour

qwelly [4]

Answer:

.009 miles/hour

Step-by-step explanation:

$\frac{7.5}{10}\frac{feet}{minutes} * \frac{1}{5280} \frac{miles}{feet} *\frac{60}{1}\frac{minutes}{hour}$

This is the method you should take with unit conversions in general, just set up fractions so the units cancel out, like the 7.5 feet cancels out with the feet in the 1/5280 so miles is left on top.

PLEASE HELP FOR 48 POINTS PLEASE!<br><br><br><br> show/explain your answer and work

pentagon [3]

Answer:

c This is the direct variation

Step-by-step explanation:

The equation for direct variation is y= kx

Solving this for k

y/x =k

So y/x must be a constant

a. 9/3 =3

2/7 does not =3 so this is not a direct variation

b 1/2 = .5

-3/6 = -.5

This is not the same so this is not a direct variation

c. 27/9 =3

18/6 =3

9/3 =3

This is a direct variation with a constant of 3

d 5/-7 = -5/7

1/-3 = -1/3

This is not the same so this is not a direct variation

Evaluate csc(-315°).

Maru [420]

Answer:

$\frac{2}{\sqrt{2} } = \sqrt{2}$

Step-by-step explanation:

Notice from the attached image that -315 degrees is the same as 45 degrees.

Recall as well that the csc function is defined as the reciprocal of the sine function: $csc(x)=\frac{1}{sin(x)}$

Then, you need to evaluate $\frac{1}{sin(45)} = 1/\frac{\sqrt{2} }{2} = \frac{2}{\sqrt{2} } =\sqrt{2}$
