Answer:

0.56 m/s

Step-by-step explanation:

The average speed of a body tells how fast is the body moving; it is calculated as:

v=\frac{d}{t}

where

d is the distance covered

t is the time elapsed

In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:

d = 1 km = 1000 m

The time elapsed to cover this distance is:

t=30 min \cdot 60 =1800 s

Therefore, Ben's average speed is:

v=\frac{1000}{1800}=0.56 m/s

How is finding volume similar to finding area?
Alenkinab [10]

Answer: finding volume is length times width times height and area is length times with so the ways they are the same are the fact that you do length times width for both and they fact that they are both solved through multiplication.

Please help ASAP<br> Trigonometry
stellarik [79]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

7)

now decide which parts we know and what we want to slove for and pick the function that has those in it

we also know that small angle down at the point b/c we can use that the inside of trianle angles add to 180

180 = 75 + 90 + X

15° = X  

where x is the angle at that sharp point on the triangle

I want to use that 15° angle in one of the above formulas as it's Opposite of that side we want to know, and also adjcent to that side we know , so i'll pick TOA  since it's got all of those in it.  Opp = x for this triangle

Tan(15) =  Opp / 15

15* Tan(15) = Opp

4.0192 = Opp

so that's x  

x = 4.0162 units , what ever they are

8)

the angle is 43° and we know the adjacent side and we want the Hypotenuse , now i'll pic  CAH  since it's got those pieces in it

Cos(43)= 31 / Hyp

some algebra just to switch Hyp out of the denominator

Hyp = 31 / Cos(43)

some tapping on my calculator

Hyp = 41.714

That's x for the second triangle

x = 41.71 units , what ever they are

A group of 4 people went to a movie. Each person bought a large drink and a small box of popcorn. They paid a total of $33.00 fo
MariettaO [177]

I'm pretty sure your answer should be $4.50 for each drink. I multiplied the price of the popcorn (3.75 including the tax) by 4, since there are 4 people, which gave me 15. Then take 15 out of 33.00 which gave me 18. Divide 18 by 4 (number of people) and get 4.5 or 4 1/2 which equals out to $4.50 for each drink.

3.75 · 4= 15

33.00 - 15= 18

18 ÷ 4= 4.5 or 4 1/2

Hope this helps! =^-^=
