Answer:
15.62
Step-by-step explanation:
The length XY is found from the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((4 -(-8))² +(-6 -4)²) = √(12² +(-10)²) = √244
d ≈ 15.62 . . . units
The length of XY is approximately 15.62 units.
Answer:
Fraction: 50/100
Percentage: 50%
Step-by-step explanation:
Find the total amount of marbles:
30+50+20=100
Number of blue marbles: 50
Fraction: 50/100
Percentage: 50%
5:3
5units:3units
5+3=8
8 units
4qt=8units
divide by 8 both sides
1/2qt=1unit
red=5unit
red=5*1/2
red=5/2qt
d
lime green=3unit
lime green=3*1/2
lime green=3/2qt
not sure what the ratio of the blue paint to the yellow paint is
I do know that
when b=amount of blue paint in quarts
yo need 5/2qt red, b qt blue, and y qt yellow, where b+y=3/2qt
and the ratio is
5:b:y, where b+y=3
can't solve fully without ration of the the blue to yellow
Answer:
3 tiles left
Step-by-step explanation:
You can only use a maximum of 9 tiles to make a perfect square. You would need 7 more tiles to make a larger square. Having used 9 tiles, you will have 3 leftover. (12 - 9 = 3)
Hope I helped!
If we consider it as a combination problem, then we could calculate the how many combinations are there if we pick up three nodes out of six nodes, and then we have:
And the answer should be 20
