If pq=3 and pq+rs=5, then 3+rs=5 is an example of the _________.

1 answer:

8 0

<span>This is an example of the substitution property of equality, meaning that if pq = 3, you may substitute 3 for pq in another related equation. So if pq+rs=5 is true, then 3+rs=5 is true as well.</span>

Answer:

As shown in picture, the circle is divided into 2 arcs, one of them is 142 deg.

Then the other one A is 360 - 142 = 218 deg (property of sum of all arcs on circle).

As the property of angle created by a tangent line:

x = (1/2) x arc A = (1/2) x 218 = 109 deg

Hope this helps!

MAY SOMEONE PLEASE HELP ME!??

1) Option C is correct

2) Option B is correct

Step-by-step explanation:

Question no 1:

We need to find the constant of proportionality

The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.

Finding k:

x = Hot pepper corn

y = chedder corn

So, y/x = 10/4 = 2.5

y/x = 20/8 = 2.5

y/x= 30/12= 2.5

So, Constant of proportionality is k = 2.5

Hence Option C is correct.

Question No 2

Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.

Baby rabbits = 5

female rabbits = 1

Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5

So, ratio of baby rabbits to female rabbits is 5

Option B is correct.

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.
