Answer:
729 square units
Step-by-step explanation:
If the width of the square is 27, then the length is also 27. After all, this is a square with four equal sides.
The area of a square is A = s^2, where s is the length of one side.
Here, A = 27^2 = 729 square units.
1/4 = 16/t.....1 elephant to 4 tigers = 16 elephants to t tigers
cross multiply
(1)(t) = (16)(4)
t = 64 <=== 64 tigers
Answer: A solid 4% chance of picking a yellow
brainliest plz
Step-by-step explanation: We first should combine 300 and 75 because those are the total values of the candies in the bag. After, we should divide the different candies by the total amount of them getting the numbers .8 for red and .2 for yellow. Since the question is that the yellow occurs but not the red and you can miss the bag you would want to calculate what the probability would be to have B happen but not A. The equation for that is:
(1 - P(A)) × P(B)
where P(A)=.8 and P(B)=.2
plugging in all things it would be
(1-.8)*.2
which equals .04 or 4%
Answer:
w = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar, then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
5w = 3(w + 2) ← distribute
5w = 3w + 6 ( subtract 3w from both sides )
2w = 6 ( divide both sides by 2 )
w = 3
Answer:
Step-by-step explanation:
Let x = the current of the river
Then 21 + x = the speed going downstream (with the current)
a nd 21 - x = the speed going upstream (against the current)
Distance = speed × time
d = st
t = d/s
Time going downstream = time going upstream
