PLEASE HELP ME IMMEDIATELY

Mathematics
1 answer:
valkas [14]3 years ago
8 0

Answer:

Angle 1 = Angle 2 = 5y -23            (Vertically opposite)

We can see that we have a triangle in the figure

Since the sum of all angles of a triangle is 180,

<em>(2x + 13) + (47) + (5y -23) = 180</em>

<em>2x + 5y + 37 = 180</em>

<em>2x + 5y = 143</em>

5y = 143 -2x -----------------(1)

Assuming l and m to be parallel

<em>angle 1  = 3x (corresponding angles)</em>

<em>5y - 23 = 3x </em>

<em>From equation (1)</em>

<em>143 -2x - 23 = 3x </em>

<em>120 = 5x </em>

x = 24 ---------------------- (2)

Using (2) in (1)

<em>5y = 143 - 2(24)</em>

<em>5y = 143 - 48</em>

<em>5y = 95</em>

y = 19

Therefore,

x = 24

y = 19

John and Annie have two distinguishable ponds. Initially, each of the ponds contains four ducks and five geese. John first picks
Sladkaya [172]

Answer: 4/9

Step-by-step explanation:

The probability that annie picks a duck Pt= the probability of picking a duck without accounting for the added one (Po)+ probability of picking the added bird and it's a duck(Pi)

Pt = Po+Pi

Since the total number of birds in the right pond is 10 after the addition of one by john

Po= 4/10

Pi= the of john adding a duck × the probability of annie picking the added bird

Pi= 4/9 × 1/10

Pi = 4/90

Pt= 4/10 + 4/90

Pt = (36+4)/90

Pt=40/90

Pt= 4/9

(This implies that the probability of picking a duck remain the same even after the addition of one bird from the left ponds because they both have equal proportions of duck and geese i.e the initial number of duck and geese in both right and left ponds are 4 and 5 respectively)

Thanks.

The price of a man's shirt went from $15 to $20. What was the percent of increase of the price of the shirt? A. 25% A. , 25%, B.
dexar [7]

Answer: 33 1/3%

Step-by-step explanation:

Percentage increase of the shirt will be calculated as:

= Price Increase / Old price × 100%

Price Increase = $20 - $15 = $5

Old price = $15

Percent increase = Price Increase / Old price × 100%

= 5/15 × 100

= 1/3 × 100

= 33 1/3%
