Answer:
Step-by-step explanation:
<u>Use the formula for angle formed by the chords:</u>
- Angle formed by 2 chords = 1/2( sum of intercepted arcs)
<u>Let the supplementary angle of x be y</u>
- x + y = 180 (straight angle)
<u>Find the value of y, using the above mentioned formula</u>
- y = 1/2(168 + 40) = 1/2(208) = 104
<u>Find the value of x:</u>
- x = 180 - y
- x = 180 - 104 = 76
Correct choice is C
275 * .15 = 41.25
275-41.25= 233.75
233.75 * .0725 = 16.95 (I rounded to the nearest thousandths. If you are not rounding, it would be 16.94)
233.75 + 16.95 = 250.70
or
233.75 + 16.94 = 250.69
Answer:
Answer
Find out the how many minutes are spent preparing.
To proof
As given
A recipe takes 90 minutes to make.
25 percent of the time is spent preparing the ingredients.
25% is written in the decimal form
= 0.25
Time spent in preparing = 0.25 × 90
= 22.5 minutes
Therefore the 22.5 minutes are spent preparing the ingredients.
Hence proved
Step-by-step explanation:
It moves the graph 5 steps downwards on the y axis.
Answer:
Step-by-step explanation:
first it is gonna be less than 13 since 65 is greater than 35. unit rate is 5/13 since 65 divided by 5 is 13. So 5 times 7 is 35. So 20 is the answer.
