Answer:
The correct answer is C. 47 3/4 oz.
Step-by-step explanation:
Since Ricki caught ten fish, and the weights of the fish were 3 2/4 oz one of them, 4 1/4 oz three of them, 4 3/4 oz two of them, and 5 2/4 oz four of them To determine their total weight, the following calculation must be performed:
3 2/4 + (4 1/4 x 3) + (4 3/4 x 2) + (5 2/4 x 4) = X
3 2/4 + 12 3/4 + 9 2/4 + 22 = X
46 7/4 = X
47 3/4 = X
Therefore, the total weight of the fish was 47 3/4 oz.
Answer:
The area is 22.5 units
The perimeter is 24.3 units
Step-by-step explanation:
The formula for the area of a triangle is A=bh(1/2)
So, base*height (5*9) is 45. Divide that by 2, and you get 22.5.
To find the perimeter, it looks like the triangle is a right triangle. To solve for that, use the Pythagorean theorem formula: a2 + b2 = c2.
5^2+9^2=c^2
25+81=106=c^2
Find the square root of 106
10.2956301
If your teacher usually asks to round, round.
I'll just round to the tenths place. 10.3
Add all the sides: 5+9+10.3
You get 24.3
Answer:
512
Step-by-step explanation:
first you would write it with the other numbers it gives which should look like this: 4+(7-5) then you do the part that is in parentheses 7-5=2 then 4x4x4x4 which equals 256 then you multiply the two together and you should end up with 512
