1 gallon = 231 in3, 1 inch = 2.54 cm)

1 answer:

7 0

1 gallon = 231 in
1 inch = 2.54 cm

Honestly, I would say it will fill up because if your solving for the amount of centimeters in a gallon then the gallon would fill up. It just makes sense to me, don't know if it's correct because what I did was take the amount of centimeters in a inch and multiply it by the total amount of inches in a gallon.

HOPE THIS HELPS! ^_^

Joe earns $14 an hour and Blaine earns $18 per hour. Joe receives a raise of $1.75 every six months, and Blaine receives a raise

Katarina [22]

After 4 interval of six months, Joe to earn same hourly rate as Blaine

Solution:

Given that,

Amount earned by Joe = $ 14 per hour

Amount earned by Blaine = $ 18 per hour

Lets assume the number of six month intervals be "x"

Joe receives a raise of $1.75 every six months

Therefore,

Joe earning: 14 + 1.75(number of six month intervals)

Equation for Joe earning: 14 + 1.75x ------- eqn 1

Blaine receives a raise of $0.75 every six months

Therefore,

Blaine earning: 18 + 0.75(number of six month intervals)

Equation for Blaine earning: 18 + 0.75x ------------ eqn 2

The number of six-month intervals it will take Joe to earn the same hourly rate as Blaine,

Eqn 1 must be equal to eqn 2

$14+1.75x = 18+0.75x\\\\1.75x-0.75x = 18-14\\\\1x = 4\\\\x = 4$

Thus after 4 interval of six months, Joe to earn same hourly rate as Blaine.

Whats is the answer to this question below?

uysha [10]

Hey there. So first we need to know what the point slope form looks like.

It is Y-Y1=M (X-X1)

Knowing this you just plug in the given information.

M is equal to 1/6. So in this case all of the options have the correct m. Next we look at the Year value. We know Y is a positive 4. So the beginning of the equation is going to look like

Y+4=1/6 ( X-X1).

Nown plug in x. It would be a negative 5. Now your final answer would be option A. Hope the explanation helped.. :)

If 55% of a number is 132 and 25% of the same number is 60, find 80% of that number.

UNO [17]

Answer:

192

Step-by-step explanation:

It is always wise to look carefully at the question to see what information is given, and what information you are asked for. You are given two different fractions of the same number, and you want the value of a third fraction of that number. That third fraction is the sum of the other two.

The value of 80% of the number will be the sum of 55% and 25% of the number.

n×80% = n×55% +n×25%

n×80% = 132 +60

n×80% = 192

80% of the number is 192.

Additional comment

Your first clue that there may be something special about this problem lies in the fact that one fraction of a number is all you need in order to find any other fraction. Here, we're given two fractions (55% and 25%), so that is more information than we need. Why? Because it simplifies the problem to one of addition. No proportions need to be solved.

If you were interested, you could determine 100% of the number to be ...

132/n = 55/100 ⇒ n = 132(100/55) = 240

60/n = 25/100 ⇒ n = 60(100/25) = 240

Then ...

0.80n = 0.80(240) = 192 . . . . 80% of the number

Or, you could write proportions for the 80% value:

80%/55% = n/132 ⇒ n = 132(80/55) = 192 . . . . 80% of the number

80%/25% = n/60 ⇒ n = 60(80/25) = 192 . . . . 80% of the number

"Look carefully" includes thinking about the ways the givens and the finds are related.

Find the sum of the measures of the interior angles of the polygon. 15-gon A. 2340° B. 2520° C. 2160° D. 1170°

Thepotemich [5.8K]

Answer:

2340

Step-by-step explanation:

Formulae for sum of interior angles is 180(n-2)

Whereby n=number of sides

$180(15 - 2) \\ 180(13) \\ = 2340degrees$
