Question 10 options:
A marine biologist is researching the population density of dolphins. The marine biologist counts 175 dolphins within a radius of 2.5 miles of a half-circle off of Clearwater Beach.

What is the population density of the dolphins?

Use 3.14 for pi, and round to the nearest whole number.

Answers

Answer:

Density = 9 dolphins / mi^2 This is the result.

Step-by-step explanation:

Number of dolphins = 175

Radius = 2.5 mi

1. - Calculate the area

Area = pi* r^2

Area = 3.14*2.5^2

Area = 3.14*6.25

Area = 19.625 mi^2

2. - Calculate the density

density = dolphins/mi^2

- Substitution

density = 175 / 19.625

Result

density = 8.9 dolphins/mi^2

Rounding to the nearest whole number

Density = 9 dolphins / mi^2

Answer:

Area of half circle = 1/2 x π x r^2

= 1/2 x 3.14 x 2.5^2

= 9.8125 miles²

For the density divide the number of dolphins by the area:

Density =population/area= 175/9.8125 = 17.83 dolphins/mile²

the population density of the dolphins is 18dolphin/miles²

Suzy makes 20 dollars an hour at her job. Bill only makes 10 dollars an hour but he has a starting bonus of 20. When will Suzy and Bill make the same amount of money for the same number of hours worked? How much will they both earn at the same time?

Answers

Answer:

2 hours

Suzy would earn $40

Bill will earn $40

they will both earn $80

Step-by-step explanation:

The total amount suzy earns is a function of the total hours worked. Let t represent time

total income of suzy = $20t eqn 1

Bill's income = starting bonus + variable pay

= $20 + $10t

We are looking for when they would earn the same amount :

20t = $20 + $10t  eqn 2

collect like terms and solve for t

10t = $20

t = 2 hours

Substitute for t in either eqn 1 or 2

20(2) = $40

Suzy would earn $40

Bill will earn $40

they will both earn $80

If there is a boy to girl ratio of 3:4, how many girls are there if there
are 18 boys? Complete the table to determine the answer.
Boys
Girls

Answers

Answer:

24 Girls

Step-by-step explanation:

3/4 = 18/x

3*x = 18*4

3x=72

3x/3=72/3

x=24

24 girls.
Because the ratio of boys to girls is 3:4, for every 3 boys there are 4 girls. 3 goes into 18 6 times and because the number of boys has increased by 6x, all we need to do is multiply 4 by 6 which is 25

Help pls! (4c+4)(2c-3)

Answers

Answer:

8c2 - 4c - 12

Step-by-step explanation:

Answer:

8c^2-4c-12

Step-by-step explanation

So you have to multiply 4c into 2c and -3 first and then 4 into 2c and -3.

(4c+4)(2c-3)

4c X 2c is 8c^2

(4c+4)(2c-3)

4c X -3 is -12c

So for the 4c multiplying in you would get 8c^2 and -12c, but we still have to multiply in the 4

4 X 2c is 8c

(4c+4)(2c-3)

4 X -3 is -12

So then we would get 8c^2-12c+8c-12, however we can still combine the -12c and the 8c.  Combining those would get -4c.  So the final answer is 8c^2-4c-12

A large square is divided into 4 smaller squares; then small left square is
divided into 4 smaller squares as well. What fraction of the large square is
shaded?

OPTIONS

4 over 5
3 over 8
4 over 9
1 over 3
1 over 2​

Answers

Answer:

The total fraction shaded is 1/2

Step-by-step explanation:

Here, we want to know the fraction shaded

As we can see, the box is originally divided into 4

So each of the 4 parts are 1/4

for the first part, we have 4 divisions;

This means each of the divisions with respect to the whole fraction will be 1/4/4 = 1/16

Now, two of these are shaded, making 1/16 and 1/16

Secondly, we have half of the 1/4 : So with respect to the whole, we have 1/4/2 = 1/8

for the third part, the whole 1/4 is shaded

and lastly, we have an unshaded 1/4

so, the total fraction shaded will be ;

1/16 + 1/16 + 1/4 + 1/8

= (1 + 1 + 4 + 2)/16 = 8/16 = 1/2
