well, we know the actual distance is 612, however the estimate is 735, is off by 735 - 612 = 123.
now if we take 612 to be the 100%, what is 123 off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 612&100\\ 123&x \end{array}\implies \cfrac{612}{123}=\cfrac{100}{x}\implies \cfrac{204}{41}=\cfrac{100}{x}\implies 204x=4100 \\\\\\ x = \cfrac{4100}{204}\implies x = \cfrac{1025}{51}\implies x \approx 20.098](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%20612%26100%5C%5C%20123%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B612%7D%7B123%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B204%7D%7B41%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20204x%3D4100%20%5C%5C%5C%5C%5C%5C%20x%20%3D%20%5Ccfrac%7B4100%7D%7B204%7D%5Cimplies%20x%20%3D%20%5Ccfrac%7B1025%7D%7B51%7D%5Cimplies%20x%20%5Capprox%2020.098)
Answer: 53 degrees
Step-by-step explanation:
Complementary angles add up to 90 degrees. Subtract Za from the 90. 90-37=53.
Answer:
here, you are simply asked to find perimeter
so add all sides to find it. soln is below
a+5+2a-1+3a-7 = 6a-3= 3(2a-1) ans
First arrange all of the distances as fractions
1 2/3 miles = 5/3
1 3/4 miles = 7/4
Now you have to make them common denominators
5/3 = 20/12
7/4 = 21/12
Now add them
20/12 + 21/12 = 41/12 miles
Now to find the distance in the last 1/2 hour.
41/12 x 1/4 = 41/48 miles
Now we have to add them, but first make them have common denominators.
41/12 = 164/48
Now to add it all up.
164/48 + 41/48 = 205/48 miles
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 5) and (x₂, y₂ ) = (- 1, 5)
m =
=
= 0
This means that the line is horizontal and parallel to the x- axis
