34 = 2b+2h
17 = b+h
b = 17-h
30 = b*h
30 = (17-h)h
30 = 17h - h^2
h^2 - 17h + 30 = 0
(h - 15)(h - 2) = 0
h = 2 or h = 15
if h = 2 then b = 30/2 = 15
if h = 15 then b = 30/15 = 2
so one side is 15 long and one side is 2 long
by the way its not a square
Answer:
Each weighs about 0.25kg
Step-by-step explanation
This is because since 15 oranges = 3.75, you should do 3.75 / 15 which gets you 0.25.
Answer:
3
Step-by-step explanation:
First right out all the data in numerical order from left to right.
2, 2, 2, 3, 4, 5, 7
The median is the middle number in the set. If there is an even amount of data points, find the average of the two middle numbers. If there is an odd number of data points, like in this data set, just take the middle number as you median.
There are 7 data points in this set so the fourth number in the set written in numerical order would be your median.
When writing this set out in numerical order, repeated numbers must be repeated, we find that the fourth, or middle, number is 3. Therefore, 3 is the median of this data set.
Answer:
4 minutes
Step-by-step explanation:
Let the time taken for them to have the same number of strawberries be x minutes.
<u>Initially</u>
Ruby: 10 strawberries
Sapphire: 30 strawberries
<u>After x minutes</u>
Ruby: (10 +3x) strawberries
Sapphire: (30 -2x) strawberries
Since we let x minutes be the amount of time that has passed when they have the same amount of strawberries,
10 +3x= 30 -2x
Bring all x terms to one side, constant to the other:
3x +2x= 30 -10
Simplify:
5x= 20
Divide both sides by 5:
x= 20 ÷5
x= 4
∴ It will take 4 minutes.
AC = 49 centimeters, you just add AB and BC together which is 49 cm!
