Step-by-step explanation:
This question requires the Pythagorean theorem.
Car A travels north 100km in two hours.
Car B travels west 160km in two hours.
Imagine a triangle the line going up is 100km
the line going left is 160km
the formula for the Pythagorean theorem is
a^2+b^2=c^2
100^2+160^2=c^2
10000+25600=c
35600=c
√35600=c

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows
Answer:
C. 84
Step-by-step explanation:
To make it easier to find the total area, you should break the shape into two parts, a triangle and a rectangle.
Step 1:
To find the rectangle area we now we have to multiply <em>l * w</em>
In this case, the length is 12 and the width is 4 so 12*4 = 48
Step 2:
To find the area of the triangle you have to do the formula A = 1/2bh where b is the base 12, and h is the height (10-4) 6. So 6*12 = 72 and 72/2 is 36
Step 3:
Last you need to add the area of both the rectangle and the triangle to get the total area of 84 sq meters
Have a good day!!!
It can not be simplified because the numerator and denominator can not be divided between the same number, so that each results an integer number.
