Answer:

The 1st error that Carlos made was in Step 2...

In step 2 , Carlos multiplied 14 only with 40. If he would have multiplied 14 with both 40 & 9 , then it could have been alright.....

A cab company charges three dollars per cab ride plus an additional two dollar per mile driven how long is a cab ride that cost
Sav [38]

If the ride cost $9 then the miles will be 3 miles.

Step-by-step explanation:

In this question we are given:

Cost of one cab ride R = $3

Additional Cost per mile M = $2

So, Total cost of Cab Ride = $3 + $2M

If cost of cab ride is $9 then we need to find the miles

$3 + $2M = $9

Solving

$2M = $9 - $3

$2M = $6

=> M = $6/$2

M = 3 miles

So, if the ride cost $9 then the miles will be 3 miles.

According to a survey on us population, the probability that a man will live seventy-five years is 0.62 and that he will live up
Vsevolod [243]
The answer is 3.71%

Given: .62 probability of reaching 75 years old and 0.023 probability of reaching 85 years old
   Since Mr. Clooney already reached 75 years old, we'll divide the probability of reaching 85 by the probability of reaching 75.
   <span>.023 / .62 = .0370967742 x 100 = 3.71%

Why? </span><span>Assume there are 1000 men who were born at the same time.
0.62 * 1000 = 620 of them will make it to 75.
0.023 * 1000 = 23 of them will make it to 85.
The proportion of those who will make it to 85 assuming that they already made it to 75 will be 23 / 620 = 0.0370967742 (same as above)</span>

An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole f
maria [59]

Answer:

X=49ft

Step-by-step explanation:

From the question we are told that:

Height of Eagle h=40ft

Angle of depression \theta=35\textdegree

 

Generally the trigonometry equation for diagonal X is mathematically given by

Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }

Cos\theta \textdegree=\frac{h}{X} }

X=\frac{40}{Cos 35 } }

X=48.83ft

X=49ft
