<em>Answer:</em>
for question 4 the asnwer is 1.7
for question 6 the answer is 2
<em>Explanation: </em>
The volume of 4 is 18 length × width × height so 3 × 3 × 2 = 18
The mass 32kg divided by the volume 18 = 1.777777778
-----------------------------------------------------------------------------------------------
The volume of 6 is 90 length × width × height so 10 × 3 × 3 = 90
The mass 180kg divided by the volume 90 = 2

You were given the data as statistics so that you can predict the number of a certain type of fish through ratio and proportion. The main focus here is then number of bluegill fish. From the given statistics, the number is 87. The total number of fishes at that time was 52+61+87 = 200. So, assuming that this composition is uniform in the said lake. We can then use the ratio from the given statistics to know the proportion of bluegills to the total fishes. Hence, we equate the two ratios:
87/200 = x/800
where x is the number of bluegills among the 800 total fishes that is in proportion to the gathered statistics. Solving for x, we determine the answer to be
x = 348
That means there are:
1,130 females
&
1,370 males.
Answer:
160 cups of lemonade and 80 packages of cookies.
Step-by-step explanation:
l = lemonade
c = cookies
l+1.5c=280
2c=l
Substitute.
3.5c=280
Simplify.
c=80
Substitute into the second equation.
l=160.
Plug it back into the equations to check.
