Answer:
Step-by-step explanation:
Pretend you see a right triangle here. From the lower end of the line go up 5 and you will be on the same horizontal as the upper end of the line. Go over 6 units and you close your triangle. This is a right triangle with legs 5 and 6 units long. We are looking for the hypotenuse of this triangle. Use Pythagorean's Theorem:
25 + 36 = ??² and
61 = ??² so
?? = √61
Formula for area of rectangles is A=lw
so Use that formula for the rectangles and use the formula for trapezoids which is A=1/2h(b1+b2)
Answer:
276 papers
Step-by-step explanation:
Make 230 into 10%=23. Multiply 23 by 2 to get 20%. Add that sum (46) to 230, to get how many more papers you graded this week=276.
Answer:
v = 13
b = 23
Step-by-step explanation:
To solve this system of equations, we can negate one equation and add it to other to cancel out one variable.
Looking at v and b, the coefficients are 6, 4 and 13, 9, respectively.
It would be easier to use the LCM of 6 and 4
Those are not equivalent.
