At a given time and place, the height of an object varies directly as the length of its shadow. If a flagpole 6 meters high cast

AfilCa [17]

Answer:

Height of the building that cast a shadow of 45 meters is 27 meters

Step-by-step explanation:

This is a direct variation and let height of the object represent H and shadow represent S

Hence H∝S

H = KS, where K=constant of proportionality

K = H/S

K = 6/10 = 0.6

Hence height of a building that cast a shadow of 45 meters

H = KS

H = 0.6 × 45 = 27 meters

What are the factors of x2+4x+3

My name is Ann [436]

Im assuming its x^2+4x+3.....for x squared right.
First get the product of two numbers that equal to 3 (+3 * +1)
But also add up to 4 (+3 + <span>+1</span>)
so you apply them to your x^2
(x+3)(x+1)

Bank robber holds up a bank and speeds off at 71 mph. Police start chasing him 10 minutes later going 78 mph. How long will it t

alexira [117]

Answer:

It takes 1.68 hours to catch up to them.

Step-by-step explanation:

The speed of robber = 71 mph

The speed of police = 78 mph

The police start 10 minutes later

by that time robber would have travelled

$distance = \frac{speed}{time}$

10 minutes =0.166667 hours

then the distance = 11.8 mph

Let them meet at distance x from the bank.

time taken by police to reach x , time = $\frac{ x}{78}$ ----------------------(1)

time taken by robber in the same time = $\frac{x-11.8}{71}$ ---------------(2)

Equating (1) and (2)

$\frac{x}{78} =\frac{ x-11.8}{71}$

$71 x = 78(x - 11.8)$

71x =78x - 920.4

920.4 = 78x - 71x

920.4 = 7x

x = 131.48

The distance where they catch up with the robber from the bank is 131.48 miles

speed of police = 78 mph

distance = 131.48 miles

time they catch up = $\frac{131.48}{78}$

= 1.68 hours
