Her answer is wrong because the product of 78.112 = 8736.
Answer:
Step-by-step explanation:
Answer:
171 degrees
Step-by-step explanation:
If angle POS is 39 degrees, then the measure of arc PS is 39 degrees
You can apply this to arc SQ and QR
So:
39+90+42= measure of arc RPQ
171 degrees= measure of arc RPQ
Answer:
Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin
Step-by-step explanation:
Given
x - y
5 - 10
10 - 20
15 - 30
Required
Determine if the data are proportional
The dataset is small; so, we can derive the relationship by observation.
By observing the x and y values, the relationship is:
y = 2x --- i.e. multiply x values by 2.
This is further proven by:
y = 2 * 5 = 10
y = 2 * 10 = 20
y = 2 * 15 = 30
y = 2 * 0 = 0 --- the origin
Hence, the dataset is proportional and it passes through the origin.
