Help please The area of the figure is blank square units
zimovet [89]

Answer:

132 square units

Step-by-step explanation:

First, I would figure out the areas of the right triangles

Left triangle:  1/2(6x8) =24 units²

Right triangle:  1/2(8x3) = 12 units²

entire rectangle between triangles: 12x8 = 96 units²

add all areas together:  24+12+96 = 132 units²

For a charity event, Jean biked at a fixed speed from Pine Bluff to Newberry. The graph shows the distance she rode along the y-
tamaranim1 [39]

Answer:

<u>The average speed or proportionality constant (y to x) of Jean biking from Pine Buff to Newberry to go to the charity event was 15 miles per hour</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance from Pine Bluff to Newberry (y axis) = 75 miles

Time it took Jean to rode her bicycle (x axis) = 5 hours

2. The proportionality constant (y to x) is?

We can calculate the answer this way:

Proportionality constant (y to x) = Distance from Pine Bluff to Newberry (y axis)/Time it took Jean to rode her bicycle (x axis)

Substituting with the real values, we have:

Proportionality constant (y to x) = 75/5

Proportionality constant (y to x) = 15 miles per hour

<u>The average speed or proportionality constant (y to x) of Jean biking from Pine Buff to Newberry to go to the charity event was 15 miles per hour</u>

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.
