Answer:
gradient = 1
Step-by-step explanation:
Calculate the gradient using the slope formula
m =
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (2, 3)
m = = 1
The answers tell you the y-intercept is zero, so all you need to do is choose the appropriate slope. Since y/x = -4, ...
.. selection A is appropriate.
From the prefix centi-, we know that there are 100 centimeters in a meter. Therefore, to convert into meters, we should divide by 100.
64.5/100=.645.
Answer:
D. 49 sq. units
Step-by-step explanation:
Find the area of the triangle up top first then multiply it by 4 to get the area of the rhombus up top:
4 x 3 = 12
12/2 = 6
6 x 4 = 24
now solve the lower square:
5 x 5 = 25
now add the two together:
25 + 24 = 49
