Mathematics
1 answer:

Answer:

3a, 13cm 5, 1:200

Step-by-step explanation:

In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm

then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200

I had difficulties with these as well. If you need extra help with the task 3 please pm me :)

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Which is greater 12 cups or 3 quarts
Zielflug [23.3K]

Neither is greater.

1 quart = 4 cups
2 quarts = 8 cups
3 quarts = 12 cups

So they're equal.

The US standard can is 4.83 inches high, 2.13 inches in diameter at the lid, and 2.60 inches in diameter at the widest point of
rewona [7]
The first thing we must do for this case is to calculate the volume of the can using the largest diameter:
 V = pi * ((d / 2) ^ 2) * (h)
 Where,
 h: height
 d: diameter.
 Calculating we have:
 V = pi * ((2.60 / 2) ^ 2) * (4.83) = 25.64 in ^ 3
 Then, to determine the amount of liquid in millimeters, we can use a simple rule of three:
 1 in ^ 3 ---> 16.3891 milliliters
 25.64 in ^ 3 ---> x
 Clearing x we have:
 x = ((25.64) / (1)) * (16.3891) = 420.22 mm
 answer
 The amount of liquid that has been bottled in milliliters is 420.22 mm
