Answer
4.5 centimeters2
Step-by-step explanation:
There are a couple ways to do this. The easiest is probably to set up a proportion.
(3.5/2800)=(6/x)
Cross multiply.
3.5x = 6(2800)
3.5x = 16800
Divide both sides by 3.5
X = 4800miles
Answer:
X = -1/3, 1/3
Step-by-step explanation:
6x^2 - x = 1
(subtract 1 from both sides)
6x^2 - x - 1 = 0
(factor)
(6x - 3) (6x + 2)
(simplify)
(2x - 1) (3x + 1)
(Solve for x in each parentheses)
2x-1= 0 and 3x+1=0
X= -1/2 X= -1/3
Seeing as they’re asking us only the total amount of ribbon (not the amount of just red or just yellow ribbon), all we have to do is add these two together.
512+212 = 724, so she used 724ft of ribbon in total (red + yellow). (I really don’t know why she would need that much, but hey, that’s her business, I guess :) )
Answer:
=20.5
Step-by-step explanation:
1. use the Pythagorean theorem: a^2+ b^2=c^2 (arms+legs squared=hypotenuse)
2. plug in the numbers to the equation:
14^2+15^2=c
225+196=c^2
421=C^2
the square root of 421 is 20.5 which is the hypotenuse of the triangle
