Answer:
A: 39.1304348% OR 39%
B: 33.3%
Step-by-step explanation:
Part A:
find the total amount of children: 90+20+80+40=230
90-20=50
i got this from taking away the amount that like watching tv and not reading so from this you know 50 of those 90 that like watching tv also like tv and reading.
80-40=40
(same explanation as 90-20=50)
then do 50 +40 which equals 90
now you need to turn it into a percentage.
90/230=
9/23
=39.1304348%
if you need round it, do so!
Part b:
40+20=60
20/60= 2/6
=1/3
=33.3%
Answer:
ft
Step-by-step explanation:
We know that the height of the object and the height of the shadow it casts are proportional. Therefore, if we let the length of the tree be
, we can set up the following proportion to solve for it:

Solving for
, we get:

(Cross-Products Property)
(Simplify)
(Divide both sides of the equation by 8 to get rid of
's coefficient)
(Simplify)
Therefore, the tree is
ft tall. Hope this helps!

Answer:
a) 50,000 bottles
b) x = 45
Step-by-step explanation:
We are given the following in the question:
The annual revenue of sun block depends on how much they sell.
Let x be the quantity of 5 oz. bottles of sun block that they make and sell each year measured in 1000 's of bottles.
For x = 10,
10,000 bottles were made and sell each year.
For x = 25,
25,000 bottles of sun block were made and sell each year.
a) x = 50

Thus, 50,000 bottles of sun block does Scura make and sell.
b) Scura produces and sells 45000 bottles of sunblock
We have to find the value of x

Thus, x = 45 if Scura produces and sells 45000 bottles of sunblock.
