Answer:
Step-by-step explanation:
We have the statement AB turns clockwise to coincide with BC.
= ABD + DBC
= 33.3° + 30.6°
= 63.9°
Now we have the statement a point E is drawn directly opposite point C. B, E, and C are on the same straight line
EBC is a straight line, so sum of angles =180°
ABE + ABD + DBC = 180°
ABE + 33.3° + 30.6° = 180°
ABE + 63.9° = 180°
ABE = 180 - 63.1
ABE = 116.9° ....
Answer:
3-Equalateral
Step-by-step explanation:
All the sides are all equal, which basically eliminates isosceles, isosceles acute, and scalene, therefore the answer is Equalateral.
Answer:
<u>30 people </u>
Step-by-step explanation:
The question is as following:
Here are the ingredients for pineapple sherbet for 6 people
800g pineapple 4 egg whites 1/2 lemon 100g caster sugar
Dan makes pineapple sherbet he uses 2 1/2 lemons
work out how many people he makes pineapple sherbet for?
=======================================================
1/2 lemon needed for pineapple sherbet for 6 people
2 1/2 lemons needed for pineapple sherbet for <u>x</u> people
1/2 : 6 = 2 1/2 : x
∴ x = ( 6 * 2 1/2 ) ÷ (1/2)
x = 6 * 5/2 * 2 = 30 people
<u>So, he make the pineapple sherbet for 30 people </u>
Answer:
72
Step-by-step explanation:
<u>Given:</u>
There were 120 people in total.
60% were parents.
<u>To find:</u>
Number of parents attended.
Solution:
1. 60% of 120
It can also be written as:
![\frac{60}{100}\times \frac{120}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B100%7D%5Ctimes%20%5Cfrac%7B120%7D%7B1%7D)
Simplify
![\frac{60}{100}\\\\=\frac{6}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B100%7D%5C%5C%5C%5C%3D%5Cfrac%7B6%7D%7B10%7D)
- Divide by common factor (2)
![\frac{6\div2}{10\div2}=\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B6%5Cdiv2%7D%7B10%5Cdiv2%7D%3D%5Cfrac%7B3%7D%7B5%7D)
2. ![\bold{\frac{3}{5}\times \frac{120}{1}}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cfrac%7B3%7D%7B5%7D%5Ctimes%20%5Cfrac%7B120%7D%7B1%7D%7D)
Multiply
![\frac{3\times120}{5\times1} = \frac{360}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Ctimes120%7D%7B5%5Ctimes1%7D%20%3D%20%5Cfrac%7B360%7D%7B5%7D)
Divide
![\frac{360}{5}= 360\div5=72](https://tex.z-dn.net/?f=%5Cfrac%7B360%7D%7B5%7D%3D%20360%5Cdiv5%3D72)
Therefore, 72 parents attended the game.
12 1/4 - 3 3/5 =
49/4 - 18/5 =
245/20 - 72/20 =
173/20 =
8 13/20
