Final answer:

The unit rates in lawns per day for Michael, Trina, and Vanessa are 8/3, 5/2, and 9/4 respectively. The unit rates are in order from least to greatest.

Explanation:

To find the unit rate in lawns per day for each person, we will divide the number of lawns mowed by the number of days it took for each person.

For Michael, he mowed 8 lawns in 3 days, so the unit rate is 8/3 lawns per day.

For Trina, she mowed 5 lawns in 2 days, so the unit rate is 5/2 lawns per day.

For Vanessa, she mowed 9 lawns in 4 days, so the unit rate is 9/4 lawns per day.

Placing the unit rates in order from least to greatest, we have:
Trina: 5/2 lawns per day
Michael: 8/3 lawns per day
Vanessa: 9/4 lawns per day

Answer:

28.8 million barrels.

Step-by-step explanation:

The percentage of production of Gasoline and Kerosene from Crude oil are 34% and 14%.

So, the Gasoline and Kerosene is totally produced by (34 + 14) = 48%.

If the production of Crude oil is 60 million barrels, then the production of Gasoline and Kerosene combined from this amount of Crude oil will be

[tex]60 \times \frac{48}{100} = 28.8[/tex] million barrels. (Answer)

By taking the sum of the percentages of Gasoline and Kerosene from the total crude oil production, we find that 48% of the 60 million barrels produced was Gasoline and Kerosene, which equates to 28.8 million barrels.

The total production from Crude oil is given as 60 million barrels. The total percentage of Gasoline and Kerosene is obtained by adding the individual percentages. Gasoline is 34% and Kerosene is 14%, so the total is 48%.
To find the total production of Gasoline and Kerosene, we must multiply this percentage by the total production.

Calculation: 48/100 * 60 million = 28.8 million barrels

So, the total production of Gasoline and Kerosene combined was 28.8 million barrels.

Answer:

The height is 5 in

Step-by-step explanation:

V = l*w*h

Substitute in what we know

360 = 24 *3*h

360 = 72h

Divide each side by 72

360/72 = 72h/72

5 = h

The height is 5 in

Answer:

The height is 5 inches

Step-by-step explanation:

Knowing that he volume of a rectangular prism is V = L*W*H, it is given that V = 360, L = 24, and W = 3. Substitute these values into the equation and get 360 = 24*3*H. This can simplify to 360 = 72*H and by dividing both sides by 72, you get H = 5. This means that he height is 5 inches.

Step-by-step explanation:

The volume of a regulation softball with given diameter is 14 cubic inches.

The volume of sphere is the measure of space that can be occupied by a sphere.  If the radius of the sphere formed is r and the volume of the sphere is V. Then, the volume of the sphere is given by: Volume of Sphere, V = (4/3)πr³.

Given that, diameter of a softball is 3 inches.

Here, radius = 3/2 = 1.5 inches

Now, volume = 4/3 ×3.14×1.5³

= 14.13 cubic inches

≈ 14 cubic inches

Therefore, the volume of a regulation softball with given diameter is 14 cubic inches.

Answer:

x=-7

Step-by-step explanation:

9x + 16 = 4x - 19

Subtract 4x from each side

9x-4x + 16 = 4x-4x - 19

5x+16 = -19

Subtract 16 from each side

5x+16 -16 = -19-16

5x = -35

Divide each side by 5

5x/5 = -35/5

x = -7

Answer:

x = -7

Step-by-step explanation:

in order to solve this , make x the subject of formula:

9x + 16 = 4x - 19

9x + 16 - 4x = -16

5x = -19 - 16

5x =-35

x = -35 / 5

Exponential growth is the process through which quantity rises over time. The population of the birds will reach 100,000 in 16.6 years from 2001.

Exponential growth is the process through which quantity rises over time. It happens when the instantaneous rate of change of a quantity with respect to time is proportionate to the amount itself.

In 2000, the total amount of a certain bird population (species of bird of paradise) was recorded at 47,000 in a city. In 2005, the same survey was made and the same bird population was estimated at 59,000.

As per the given information the population of the bird changed from 47,000 to 59,000 in five years, therefore, we can write,

59,000 = 47,000(1+r)⁵

(59/47) = (1+r)⁵

1.046528 = 1+r

r = 0.046528

Now, the time it will take for the population to reach 100,000 will be,

100,000 = 47,000(1+0.046528)ⁿ

[tex]\dfrac{\log(\frac{100}{47})}{\log{1.046528}} = n\\\\n = 16.6019[/tex]

Thus, the population of the birds will reach 100,000 in 16.6 years from 2001.

Final answer:

Using the given data, the bird population is increasing at a rate of 2,400 birds per year. If this rate continues, the population is expected to reach 100,000 by the year 2022.

Explanation:

The question involves calculating the year when the bird population will reach a certain number, assuming a consistent growth pattern. Based on the data provided:

First, determine the annual growth rate over the 5-year period from 2000 to 2005:

Growth = 59,000 - 47,000 = 12,000 birds

Annual growth rate = Growth / 5 years = 12,000 / 5 = 2,400 birds/year

Next, calculate the number of years needed for the population to grow from 59,000 (in 2005) to 100,000:

Number of years = (Target population - Population in 2005) / Annual growth rate

= (100,000 - 59,000) / 2,400

≈ 17.08 years

To find the target year, add the number of years to 2005 and round to the nearest year:

Target year = 2005 + 17.08 ≈ 2022

Therefore, if the trend continues, the bird population is predicted to reach 100,000 in 2022

OK.

Alexandra bought 3 apples and 6 bananas

Number of apples = a

Number of bananas = b

From the information given, the equation to use will be:

a + b = 9 ....... i

1.75a + 0.40b = 7.65 ...... ii

From equation i, a = 9 - b ...... iii

Put equation iii into ii

1.75a + 0.40b = 7.65

1.75(9 - b) + 0.4b = 7.65

15.75 - 1.75b + 0.4b = 7.65

Collect like terms

-1.75b + 0.4b = 7.65 - 15.75

-1.35b = -8.1

b = 8.1/1.35

b = 6

She bought 6 bananas

Number of apples bought = 9 - 6 = 3 apples.
