We can write a proportion for this problem
10,000drops of a liquid is 10 fluid ounces
100 drops of a liquid is x fluid ounces
x=100*10/10000 =1/10 = 0.1 fluid ounces
Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40
We are given height function of the bridge
h(x) =-0.5(x-4)^2 +2.
Where height is the height of the bridge in feet and x is the distance between two bases.
We have height =0 on the base of the bridge. In order to find the both bases, we need to plug h(x) as 0 and solve for x.
-0.5(x-4)^2 +2 = 0
Taking square root on both sides, we get
We got horizontal distances 2 feet and 6 feet.
Therefore, correct option is D.
m∠8 would be the first option, which is 50°.
We know this because m∠4 and m∠8 are corresponding angles, meaning that they are formed by a shape that kind of looks like an F. Corresponding angles are equal, so if m∠4 is 50°, that means that m∠8 is as well.
I hope this helps!
