Answer:
850 red beads
Step-by-step explanation:
One way to do this problem is to set a proportion.
red beads/red beads = total beads/total beads
Let x = the no. of red beads in the bag
x/17 = 7500/150
x = 17(7500)/150 = 850 red beads
Answer:5 2/3
Step-by-step explanation:
add 2 and 3
then you add 1/3 and 1/3
2+3=5
1/3 + 1/3=2/3
5 2/3
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5

The area of an equilateral triangle is (1/2)bh. The base is 5, so using the Pythagorean theorem we get h by:
5² = (5/2)² +h²
h = √18.75
h = 4.33
So the area of one face is (1/2)(5)(4.33) = 10.825m²
The total area is 4(10.825m²) = 43.3m²
