Answer:
7.1 miles
Step-by-step explanation:
From the park to the library is a diagonal line. We can use pythagorean theorem.
Change in y - 7
Change in x - 1
7^2 + 1^2 = x^2
(x is the distance between the library and park)
49 + 1 = x^2
50 = x^2
That's around 7.
When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get
which equals
Answer:
A = 36 units ^2
Step-by-step explanation:
The area of the polygon is given by
A = b*h
the base is 9 and the height is 4
A = 9*4
A = 36 units ^2
There would be 203,759 total registered doctors that year.
Answer:
x = -6
y = 8
Step-by-step explanation:
Using substitution method.
2x + y = -4 -----------(I)
y = - 4 - 2x -----------(II)
5x + 3y = -6 -------------------(III)
Substitute y = -4 -2x in equation (III)
5x + 3(-4-2x) = - 6
5x - 12 - 6x = -6
5x - 6x - 12 = -6
Combine like terms
-x - 12 = -6 {Add 12 to both sides}
-x = -6 + 12
-x = 6 {Multiply by (-1)}
x = -6
Substitute x = -6 in equation (II)
y = - 4 - 2*(-6)
= -4 + 12
y = 8
