Answer:
1. 6.4 meters of streamers left to make pompoms
2. He will be able to make 8 pompoms
Step-by-step explanation:
1.
4 x 1.6 = 5.6 meters were used to make decorations.
Then we do 12 - 5.6 = 6.4
2.
per one pompom it takes 0.8 meters of streamers.
6.4 is the left over so we do
6.4 divided by 0.8 = 8 pompoms you can make
Answer:
13 children and 9 adults if the total cost is $152.5
Step-by-step explanation:
Let x children and y adults
x + y = 22 (1)
5.5x + 9y = 125.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 125.5
5.5x + 198 - 9x = 125.5
-3.5x = 125.5 - 198
-3.5x = -72.5
x = 20.7
y = 22 - x = 1.3
Which is not possible
If the total cost is $152.5
x + y = 22 (1)
5.5x + 9y = 152.5 (2)
y = 22 - x
5.5x + 9(22 - x) = 152.5
5.5x + 198 - 9x = 152.5
-3.5x = 152.5 - 198
-3.5x = -45.5
x = 13
y = 22 - 13 = 9
Answer:
It is the third one down.
Step-by-step explanation:
The two smaller angles would be the same measurement because the angle bisector cuts the big angle down the middle. So, if the big angle was 90°, the two smaller angels would be 45°.
Multiply the price of a flash drive by the number he buys:
