How fast is the train going if it can travel 100 miles in 30 minutes?

Mathematics
1 answer:
DerKrebs [107]2 years ago
4 0

30 min = 30/60 hr = 0.5 hr

d = rt

100 = r*0.5

100/0.5 = r

200 = r

r = 200 mph.

We know that Rate = distance/time

(30 minutes is .5 hour)

Rate=100 mile/.5 hour

Divide and we get:

Rate=200 MPH

(Hint: MPH is Miles per Hour---Per means "for each")

Make sense?

(50 POINTS!!!) find the total surface area and volume, then multiply by $0.004. please show your work!!
mrs_skeptik [129]

The Total surface area of the square pyramid = 115.2 in.²

The Volume of the square pyramid = 1,024 in.³.

<h3>What is the Total Surface Area of a Square Pyramid?</h3>

The total surface are of a square pyramid is given as: TSA = SA = 1/2(P × l), where:

P = perimeter of the square base

l = slant height of the pyramid

<h3>What is the Volume of a Square Pyramid?</h3>

The volume of a square pyramid = 1/3(a³ × h), where:

a = edge of the square base

h = height of the pyramid

Find the Total surface area of the Pyramid:

P = 4(a) = 4(8) = 32 in.

l = 7.2 in.

Total surface area of the square pyramid = 1/2(32 × 7.2)

Total surface area of the square pyramid = 115.2 in.²

Volume of the square pyramid:

a = 8 in.

h = 6 in.

Volume of the square pyramid = 1/3(8³ × 6)

Volume of the square pyramid = 1,024 in.³

Which graph represents the function f(x) =-lx-2l-1​
zimovet [89]

It’s the second one from the right

Since there’s a - behind x it means it has to be facing down so it’s either 2 or 4

Now it’s x-2 and we know that x moves the opposite so it needs to move 2 to the right so the answer is 2

Which expression is equivalent to log3(x + 4)?
solmaris [256]
ANSWER

The third option is the correct answer

log3(x + 4)   =  log(3)  +  log(x + 4)


EXPLANATION

The expression given to us is

log3(x + 4)   =  log(3)  +  log(x + 4)


This logarithmic expression is of the form

log(A \times B)


So we use the multiplication law of logarithm which is given by



log(A \times B) =  log(  A )  +  log( B )


We therefore set

A  = 3

B = x + 4


The given expression now becomes,


log3(x + 4)   =  log(3)  +  log(x + 4)
