A roller coaster climbs 120 feet from ground level then drops 75 feet before climbing another 105 feet. How far above ground is
Ostrovityanka [42]

Answer:

The roller coaster is 155 feet above the ground.

Step-by-step explanation:

Given:

The roller coaster climbs 120 feet from ground level.

Then drops 75 feet

Then again climbs 105 feet

To find distance of roller coaster above the ground now we will subtract the drop in level from the rise and then add the second rise to the difference.

This can be evaluated as:

125\ ft-75\ ft+105\ ft

⇒ 50\ ft + 105\ ft

⇒ 155\ ft

Thus the roller coaster is 155 feet above the ground.

Twice a number plus twice a second number is 310. The difference between the numbers is 55. Find the numbers by writing and solv
yan [13]

The numbers are 105 and 50

<em><u>Solution:</u></em>

Let "x" be the first number

Let "y' be the second number

Twice a number plus twice a second number is 310

Therefore,

twice of x + twice of y = 310

2x + 2y = 310 ---------- eqn 1

The difference between the numbers is 55

x - y = 55 -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 2,

x = 55 + y ------ eqn 3

<em><u>Substitute eqn 3 in eqn 1</u></em>

2(55 + y) + 2y = 310

110 + 2y + 2y = 310

4y = 310 - 110

4y = 200

<h3>y = 50</h3>

<em><u>Substitute y = 50 in eqn 3</u></em>

x = 55 + 50

<h3>x = 105</h3>

Thus the numbers are 105 and 50

Scrat [10]

Volume of 1/4 gal

= Volume of 2/3 bin


Volume(x gal)

= Volume( 1 bin)


So, (1/4)/(2/3)

= x/1


(1/4)/(2/3)

= x



(1/4)/(3/2)

x = 3/8 (Total balance required to fill the entire bin)




In order to fill the bin, the additional gallons need to be added to the initial 1/4 gallon



Therefore, 3/8 - 1/4 = 1/8 gallons










Hope that helps!!!!
