Answer:
9/1000
Step-by-step explanation:
Because 1 m = 1000 mm, the scale factor is 9/1000
For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14
Yes, you are right. the length is 3, the height is 2, and the width is 1
Answer:
58 in^2.
Step-by-step explanation:
This is the sum of the area of 4 small rectangles + the area of the 2 larger rectangles
= 2*4*1 + 2*5*1 + 2*4*5
= 8 + 10 + 40
= 58 in^2
