Answer:
All pair COMBINATION are supplementary (Opposite)
Step-by-step explanation:
According to theorem about inscribed quadrilateral
- The opposite interior angles of an inscribed quadrilateral are supplementary .
- I.e there sum is equal to 180°
<O+<Q=180
<P+<R=180
Okay, so supplementary angles = 180 degrees.
Starting equation : 4y + 7 + 9y + 4 = 180
Combine like terms : 13y + 11 = 180
Subtract 11 from both sides : 13y = 169
Divide 13 from both sides : y = 13
Insert y value into original m<2 equation : 9(13) + 4
Solve : 121 degrees
If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.
4(13) + 7 = 59
59 + 121 = 180
Y = 1/(x - -2)
y = 1/(x + 2)
I moves the graph 2 units to the left
Answer:
D. 2/7
Step-by-step explanation:
We assume that the intention is that one of the places is chosen at random from the list of 7 places.
2 of those are cities in North America, so the probability that a place randomly chosen from this list is a city in North America is ...
P(A & B) = 2/7
(a)The ratio of the number of machine to the number of crates packed is 1:4.5
(b) crates of oranges in 90 pack per day by machine is 405.
What is Ratio?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
Given that;
40 identical machines in a factory pack 180 crates of oranges per day
So,
a) The ratio of the number of machines to the number of crates packed per day is:
40/180 = 1:4.5
b) crates of oranges would 90 of these machines pack per day is
40/180 = 90/x
x = 4.5 x 90
x = 405
