3(the fee per hour) * 5(the number of hours) = 15
15 + 10(the initial fee) = 25
The answer is true.
When ANY number is multiplied by its own reciprocal, the product is ' 1 '.
Answer:
Correct choices are a, b, e
Step-by-step explanation:
As per diagram, the circles are equal.
<u>Since the distance AB is the radius of both circles:</u>
- AB = AC = BC = BD = AD = r
<u>So the answer choices:</u>
a. AC = BC
b. AC = BD
C. CD = AB
- Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3
d. ABCD is a square
- Incorrect. ACBD is rhombus
e. ABD is an equilateral triangle
- Correct, all three sides are equal to r
f. CD = AB + AB
Answer:
• linear angles
• supplementary angles (all linear angles are supplementary)
Step-by-step explanation:
If the angles share a side and are measured in opposite directions from that side, the non-common edges of these angles form a straight line, so these angles are sometimes called "linear" angles.
Since their sum is 180°, they are always "supplementary" angles. (Supplementary angles need not share a vertex or a side.)
