you would have 32 multiplication and 16 addition I believe because.
2 2x2 matrices Is 8 multiplication and 4 addition
4/3 times 5/2 is 20/6, or 10/3. 3 1/3 pounds is the answer
Answer: 75 students.
Step-by-step explanation:
In the data set we have a total of 10 + 8 + 7 + 5 = 30 students.
of those, 10 want to go to the park, the percentage is:
(10/30)*100% = 33.3%
Then, out of the 225, we can expect that a 33.3% (or 0.333 in decimal form) want to go to the park, this is:
N = 225*0.333% = 74.925
We can roud it up, and get N = 75
So Sally can expect that 75 students want to go to the park
By the Pythagorean Theorem, the longest side of a right triangle squared is equal to the sum of the squared sides...
h^2=x^2+y^2, where h=hypontenuse, and x and y are the side lengths...
87^2=w^2+63^2
w^2=87^2-63^2
w^2=3600
w=√3600
w=60 in
So the base of the frame is 60 inches wide.
An 8% slope up is 422.4 feet up in one mile.
An 8% slope down is 422.4 feet down in one mile.
1 mile = 5,280 feet
8% of 1mile = 0.08 x 5,280-ft = 422.4-ft
