Kevin can travel 22 1/2 miles in 1/3 hour. what is his average speed in miles per hour

klemol [59]

We know that speed * time = distance

Before we start we need to make sure the units for all three numbers are right

The time is 1/3 of a hour, 1/3*60 = 20 minutes

x * 20 = 22.5

x *2 * 10 = 22.5

2x = 2.25

x = 1.125

PLEASE HELP WITH GEOMETRY IM STUCK!?}

Ilya [14]

Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

$cos(37)=\frac{11}{x}$

step 1 multiply each side by x

$cos(37)*x=xcos(37)\\\frac{11}{x} *x=11$

now we have $xcos(37)=11$

step 2 divide each side by cos(37)

$\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\$

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8

Alinara [238K]

Answer:

37.5

Step-by-step explanation:

WHY???

All others have numbers that add up to 6 (1+0+5+0)

It is a decimal

All others can be divided by 5

All others are at least 3 digits

All others don't contain a seven or a three

lesya [120]

Answer:

I believe the answer is C.

Step-by-step explanation:

if you distribute it would just be c^5D^5, just another way of multiply.

Hope my answer has helped you and if not I am sorry.
