7253(8x4v) when v = 13

Fittoniya [83]

Answer:

3039007

Step-by-step explanation:

V= 13

Substitue (v) for 13

7253(8*4(13))

Go by the rules be PEMDAS

First you the parentheses

4 times 13= 52

52 times 8= 416

Now you just multiply the two numbers

416 times 7253= 3039007

An express train travels 80km/h from Ironton to Wildwood. A local train, traveling at 48km/h, takes 2 hours longer for the same

masha68 [24]

Answer:

They are 240 kilometers apart.

Step-by-step explanation:

This question can be solved using the following relation:

$v = \frac{d}{t}$

In which v is the velocity, d is the distance and t is the time.

An express train travels 80km/h from Ironton to Wildwood.

Here we have $v = 80, t = x$ . So

$v = \frac{d}{t}$

$80 = \frac{d}{x}$

$d = 80x$

A local train, traveling at 48km/h, takes 2 hours longer for the same trip.

This means that when $v = 48, t = x + 2[tex]. So[tex]v = \frac{d}{t}$

$48 = \frac{d}{x+2}$

Since $d = 80x$

$48 = \frac{80x}{x+2}$

Applying cross multiplication

$80x = 48(x + 2)$

$80x = 48x + 96$

$32x = 96$

$x = \frac{96}{32}$

$x = 3$

So the distance is:

$d = 80x = 80*3 = 240$

They are 240 kilometers apart.

In △ABC, GE=27 in. What is the length of BE¯¯¯¯¯? Enter your answer in the box. 81 in. An acute triangle A B C is drawn. E is th

mariarad [96]

Recall that the centroid of a triangle (the point where the three medians intersect) divides each median into parts in the ratio 2:1, with the centroid being twice as close to the midpoint of a side as it is to the opposite vertex.

Thus, the ratio of segment EG to segment BG is 1 : 2

Therefore, given that segment EG = 27 in, then segment BG = 2(27) = 54 in. and segment BE = 27 + 54 = 81 in.
