Answer:
39 feet
Step-by-step explanation:
From the question;
let length of ladder =x feet
height of ladder will be=x-3 feet
ground distance of ladder bottom to building=15 feet
Applying Pythagorean relation
a²+b²=c²
where a=15 feet b=x-3 feet and c=x feet thus
x²-15²=(x-3)²
x²-225=x²-6x+9
collect like term
x²-x²-225-9=-6x
-234= -6x
x= 39 feet length of ladder
distance from ground to top of ladder= 39-3=36 feet
7 girls on a bus, each has two legs. 7 * 2 = 14.
Each girl has 7 backpacks. So 7 * 7 = 49.
49 * 7 = 343 cats in total
343 * 4 = 1,372 cat legs.
343 * 7 = 2401 small cats
2401 * 4 = 9,604 cat legs
14 + 1,372 + 2,401, + 9,604 = 10,990 legs in total
To simplify begin by distributing the multiplication outside the parenthesis:
Answer:
1/7
Step-by-step explanation:
The list of numbers generated is; 0, 1, 2, 3, 4, 5, 6,
There are 7 possible outcomes and each outcome is equally likely. The probability or chance that each number will occur is given by;
number of times the number occurs / 7
In our case, each number occurs only once, so the chance will be;
1/7
