The average weight of 7 potted plants is 23 pounds. An 8th potted plant is added to the pallet,

cluponka [151]

Answer:

The weight of the 8th plant is 39lb

Step-by-step explanation:

Given:

Average Weight of 7 plants = 23lb

Average Weight of 8 plants = 25lb

Required:

Weight of the 8th plant

To solve this, the total weight of the initial 7 plants need to be calculated;

$Average = \frac{Sum-of-weights}{Number-of-Plants}$

Substitute 23 for Average and 7 for Number of plants

$23 = \frac{Sum-of-weights}{7}$

Multiply both sides by 7

$7 * 23 = \frac{Sum-of-weights}{7} * 7$

$161 = Sum-of-weights$

Hence, the 7 plants weigh 161

Represent the weight of the 8th plant with E

When the 8th plant is added;

The sum of the weight becomes 161 + E

And the number of plants becomes 8

The average is calculated as thus

$Average = \frac{Sum-of-weights}{Number-of-Plants}$

$25 = \frac{161 + E}{8}$

Multiply both sides by 8

$8 * 25 = \frac{161 + E}{8} * 8$

$200 = 161 + E$

Subtract 161 from both sides

$200 -161 = 161 - 161 + E$

$39 = E$

Reorder

$E = 39$

Hence, the weight of the 8th plant is 39lb

Joan poured 7/8 liter of water into a bottle. It filled 5/6 of the bottle.How many liters of water will completely fill the bott

stepan [7]

Let's set up some equations.

We know that 7/8 of a liter fills up our bottle 5/6 of the way. Thus 7/8=5/6 * b.

Now, let's divide both sides by 5/6 to get b = 21/20. However, none of the answer choices provided are correct. Let's look at each one to determine why it's not correct.

A. This answer is false because 35/48 < 7/8. If 7/8 of a liter doesn't completely fill up the bottle, there is no way that a value less than 7/8 can fill up the bottle - it's impossible.

B. Same case as answer A, but 11/38 instead of 35/48.

C. Same case as answer A, but 11/20 instead of 35/48.

D. This answer however is more than 35/48, so is it correct? No. 113/35 is just over 3. Since 7/8 of a liter almost fills the bottle but does not quite completely fill it, there is no way that adding 2 more liters can fill up the bottle just the tiny 1/6 of the way. That is disproportional and is thus wrong.
