The amount a spring will stretch varies directly with the amount of weight attached to the spring. If a spring stretches 2.1 inc

aleksklad [387]

Answer:

$1.05\ in$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

x -----> the amount of weight

y ----- the amount a spring will stretch

we know that

For x=80 lb, y=2.1 in

<em>Find the value of k (constant of proportionality)</em>

$k=y/x$

substitute the values

$k=2.1/80$

The linear equation is

$y=(2.1/80)x$

How far will it stretch when 40 pounds is attached?

For x=40 lb

substitute the value of x in the linear equation and solve for y

$y=(2.1/80)(40)=1.05\ in$

While painting the side of his house, Jason positioned his ladder so that the top was 16 feet

kenny6666 [7]

Answer: $8.71\ ft$

Step-by-step explanation:

Given

Ladder is 16 ft from bottom and 12 away from the base of the wall

In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall

In both the cases the length of ladder remains the same

Using Pythagoras theorem, we can write

$\Rightarrow 16^2+12^2=L^2\ldots(i)\\\Rightarrow 18^2+x^2=L^2\ldots(ii)\\\text{From (i) and (ii)}\\\Rightarrow 16^2+12^2=18^2+x^2\\\Rightarrow x^2=256+144-324\\\Rightarrow x^2=76\\\Rightarrow x=\sqrt{76}\\\Rightarrow x=8.71\ ft$

The histogram represents the number of gallons of gasoline that drivers purchase weekly. Which bar represents the number of gall

padilas [110]

Answer:

option B) Bar 2

Step-by-step explanation:

The histogram represent the number of gallons of gasoline on x axis.

The number of drivers purchase weekly on y axis.

In this histogram 5 Bars are shown.

First bar represents = 5 drivers

Second bar represents = 6 drivers

Third bar represents = 1 driver

Fourth bar represents = 3 drivers

Fifth bar represents = = 4 drivers

So the second bar represents the the number of gallons most drivers purchased during the week.

Therefore, option B) Bar 2 is the correct answer.
