Answer:
There are 33 students
Step-by-step explanation:
Because 7:4 should be in multiple of 11
Answer: w - 7
Step-by-step explanation:
The expression is simply less 7 less than w, or w - 7.
So it's part of a diameter with the 40, so you should have taken 180-40=140 then it should have been set equal to 140. So 22x+8=140 then 22x=132 then 132÷22=6 so x=6
Answer: 2.6
Step-by-step explanation:
Step 1: Calculate the mean of Shade's plant heights.
= 7+12+12+8+9+8+8+8/8
= 72/8
=9
Step 2: Calculate the range of Shade's plant heights. Range is highest minus lowest number. This will be:
12 - 7 = 5
Step 3: Calculate the mean of Sun plant heights.
19+24+20+23+24+23+23+20/8
= 176/8
= 22
Step 4: Find the range of Sun plants height.
= 24 - 19 = 5
Step 5: Find the difference of means
= 22 - 9
= 13
Step 6: Divide the difference of means by the range.
= 13 ÷ 5
= 2.6
We know that one row contains four units each and there are five rows. To find out the area of the shape, we do:
5 (row) × 4 (units) = 20 units
So the area of the shape is 20 units².
