Answer:
Portion of walking in degrees = 72°
Step-by-step explanation:
The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better
First calculate the percentage of walking from a total of all activities.
Percentage of walking = 10/50 · 100%
Percentage of walking = 20%
It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.
We know that the whole circle is equals to 360°
Circle = 360°
We need to calculate 20% of 360°, which will represent the portion of walking in degrees.
Portion of walking in degrees = 20/100 · 360°
Portion of walking in degrees = 72°
Answer:
n
Step-by-step explanation:
The statement of the question tells us that 45% of the customers getting an oil change will have their car tires rotated. Therefore:
probability of both = 0.7 x 0.45
= 0.315
= 31.5%
Answer:
Statements: Reasons:
1) ∠2 and ∠4 are vertical angles given
2) limes <em>m </em>and <em>n </em>intersect at <em>P </em>definition of vertical angles
3) ∠3 and ∠4 are linear pair definition of linear pair
4) ∠2 and ∠3 are linear pair definition of linear pair
5) m∠3 + m∠4 =180 angle addition postulate
6) m∠2 + m∠3 =180 angle addition postulate
7) m∠2 + m∠3 = m∠3 + m∠4 substitution property
8) m∠2 = m∠4 subtraction property
9) ∠2 ≅ ∠4 definition of congruent(≅) angles
