Pamela drove her car 999999 kilometers and used 999 liters of fuel. She wants to know how many kilometers (k) right parenthesis she can drive with 121212 liters of fuel. She assumes the relationship between kilometers and fuel is proportional.How many kilometers can Pamela drive with 121212 liters of fuel?

Answer:

The length can be 5 and the width 10.

Step-by-step explanation:

perimeter is equal to 2L + 2W

area is equal to L * W

you get 2 equations:

30 = 2L + 2W

50 = L*W

we'll solve by substitution.

you can use either equation to solve for either variable.

we'll use the second equation to solve for L.

second equation is:

50 = L*W

divide both sides of this equation by W to get:

L = 50/W

we now have a value of L that we can substitute in the first equation which we can then use to solve for W.

the first equation is:

30 = 2L + 2W

replace L with 50/W to get:

30 = 2*(50/W) + 2W

simplify to get:

30 = 100/W + 2W

multiply both sides of this equation by W to get:

30W = 100 + 2W^2

subtract 30W from both sides of this equation to get:

2W^2 - 30W + 100 = 0

factor this equation to get:

(2W - 20) * (W - 5) = 0

solve for W to get:

W = 10 or W = 5

if W = 10, then use the equation of 50 = L*W to get L = 5

if W = 5, then use the equation of 50 = L*W to get L = 10

you have 2 possible solutions.

L = 5 and W = 10 or:

L = 10 and W = 5

both are plausible so we'll test them both out.

when L = 5 and W = 10:

the first equation becomes 2*5 + 2*10 = 10 + 20 = 30

the second equation becomes 5*10 = 50

both equations confirm that the solution of L = 5 and W = 10 is good.

when L = 10 andW = 5:

the first equation becomes 2*10 + 2*5 = 20 + 10 = 30

the second equation becomes 10*5 = 5

both equations confirm that the solution of L = 10 and W = 5 is good.

the ticket can have either:

a length of 5 and a width of 10 or:

a length of 10 and a width of 5.

since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.

alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.

mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.

Step-by-step explanation: it would be josh has 2 jars of jelly

The number of coins in the red jar is 83 and the number of coins in the red jar is 110.

The blue jar has 27 more coins than the red jar. There are total of 193 coins.

The number of coins in each jar can be calculated as follows:

Using equation,

let

x = coins in the red jar

Therefore,

coins in the blue jar = 27 + x

Therefore,

total coins in the jars = x + 27 + x

193 = x + x + 27

193 - 27 = 2x

166 = 2x

divide both sides by 2

x = 166 / 2

x = 83

Therefore,

number of coins in the red jar = 83

number of coins in the blue jar = 83 + 27 = 110

Answer:

theoretical- what is expected to happen, 1/2

experimental- what actually happened, 1/10

Step-by-step explanation:

theoretical does not always mean that it will happen, such as flipping a coin.

it will say there is a 1/2 chance to get heads or tail.

experimental is what actually happens when you test it out. say you flip a coin 10 times and only get heads 3 times. if it was the theoretical possibility then it would say 5 heads and 5 tails.

Step-by-step explanation:

7 whole enchiladas he can make with 5/6 jars of sauce.

Given that, Tony is making chicken enchiladas. He needs 1/8 jar of sauce for each enchilada.

We need to find out how many whole enchiladas can he make with 5/6 jars of sauce.

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Based on the given condition we can formulate: 5/6 ÷ 1/8

=5/6 × 8

=5/3 × 4

= 20/3

=6.666≈7

Therefore, 7 whole enchiladas he can make with 5/6 jars of sauce.
