The unit of metric measurement used
when measuring the width of your
pencil point is millimeters
Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²
Answer:Julie's average score was 76
Step-by-step explanation:
The formula for Average or mean is expressed as
Average = sum of terms / total number of terms.
Julie's first three test scores in biology were 65, 90 and 73.
The sum of the scores would be
65 + 90 + 73 = 228
The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,
Average = 228/3 = 76
Solving it and nearing it to the hundredth would be 9.169 :)
180
The exterior angle of a triangle + the adjacent interior angle are supplementary, that is sum to 180°, thus
the exterior angle = 180 - adjacent interior angle
