Answer:
480
Step-by-step explanation:
We can set up a proportion:
#students that eat carrots / #students surveyed=#students that eat carrots / #students surveyed
x will equal the number of students in Sarah's school who eat carrots.
30/50 = x/800
We can simplify
3/5=x/800
We cross multiply
5x=3*800
5x=2400
x=480
Hope this helps!
Answer:
B
Step-by-step explanation:
draw a right angled triangle with the right angle in the bottom left
label P as the bottome left corner and write its coordinates next to it
do same with Q
the length of the triangle is 4 (8-4 = 4)
the height is 10 (12-2 = 10)
use pythagoras to work out the hypotenuse:
Answer:
the room is -1m by 14m
Step-by-step explanation:
what you do to find it is first find x.
the perimeter is 26, and one side is 15 meters longer than the other(twice).
So the equation is:
x + (x + 15) + x + (x + 15) = 26
2x + 2(x + 15) = 26
2x + 2x + 30 = 26
4x + 30 = 26
26 - 4x = 30
26 - 26 - 4x = 30 - 26
-4x = 4
-4x/-4 = 4/-4
x = -1
Now we have two sides of the room. Now we want the 15m longer ones...
-1 + 15 = 14
so the dimensions are -1 by 14, or -1x14

If not, hope it helps anyway.
Use zeroes as place holders
0.02468
0.02400
so clearly 0.02468 is greater than 0.02400
so yes, 0.02468 is greater than 0.024
but remember don't use those extra zeroes in ur actual answer.
