Lucy makes green paint by mixing yellow and blue paint in the ratio 5:2. Blue paint costs

ahrayia [7]

Answer:

No, she won’t make a profit

Step-by-step explanation:

Here, we are interested in determining if Lucy made a profit or a loss.

The cost of blue paint is 30 pounds for 5 liters. This means that a liter of blue paint is 30/5 = 6 pounds per liter

The cost of yellow paint is 28 pounds per 7 liters, the cost per liter is 28/7 = 4 pounds per liter

Now, in her mixing, she mixes 5 parts of yellow paint and 2 parts of blue paint.

This means that she mixed them the ratio as follows per liter;

For yellow, we have; 5/(5+2) = 5/7

For blue we have 2/(5+2) = 2/7

Now since a liter of yellow paint cost 4 pounds

5/7 of a liter will cost 5/7 * 4 = 20/7 pounds

For the blue paint, a liter cost 6 pounds, 2/7 of a liter will cost 2/7 * 6 = 12/7

The total cost in pounds in this;

20/7 + 12/7 = 32/7 = £4.57 pounds to 2 decimal place

Now she sells her green paint product at £4.5 per liter. Since this is less than the cost price of production which is £4.57, she is running at a loss

The table shows the average weight of animals. How many more tons does a blue whale weigh than an African elephant? Explain how

AVprozaik [17]

Answer:

The African elephant weighs <u>111.5 tons</u> less than a blue whale.

Step-by-step explanation:

Given:

Animal Weight(pounds)

African Elephant 15,000

Blue Whale 238,000

Now, to find the weight of how more tons does a blue whale weigh than an African elephant.

As given, 1 ton = 2,000 pounds.

So, to convert the weight from pound to tons by dividing:

African elephant $=15000\div 2000=7.5\ tons.$

Blue whale $=238000\div 2000=119\ tons.$

Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:

$Blue\ whale - African\ elephant$

$=119 tons-7.5tons$

$=111.5\ tons$

Therefore, the African elephant weighs 111.5 tons less than a blue whale.

Express each fraction as a percent. Round your answer to the nearest whole number.

GREYUIT [131]

Answer:

60.8% which rounds to 61%

42.61% which rounds to 43%

29.14% which rounds to 29%

Step-by-step explanation:

So, there are two ways to do this, either perform the division as you see it, or make it so it is some number over 100 instead of what it is.

For the first one if you just do the division, either with long division or with a calculator you get exactly .608. The other two are not as nice, jsut a warning. From here you multiply it by 100 to get the percent. For instance with .5 (which is half) the corresponding percent is 50%, which is after you multiply .5 by 100). if you need help with the division let me know and I can work you through one.

if we go with the second way we would want to make 125 into 100. To do this we need to multiply it by something to get to 100. Or in other words, 125x=100. This winds up being .8, or 8/10 You could also see it as dividing 125 by 1.25 or 5/4, if you need help with this (or any part in particular really) let me know.

Anyway, since one part of the fraction is being multiplied or divided, the other part does too, so you would take 76 and do the same. Whichever number you use you get 60.8. You don't have to multiply this by 100 since it is already part of a fraction over 100.

Again, let me know if you need more help, I will leave the other two to you unless you need the help.
