200 grams of fertilizer are used for each tree in an orchard containing 1200 trees. at $2.75 per kilogram of fertilizer, how much does it cost to fertilize the orchard ?

Step-by-step explanation:

The expression for the pressure in terms of force is as follows;

[tex]P= \frac{F}{A}[/tex]

Here, F is the force, P is the pressure and A is the area.

It is given in the problem that an object exerts 140 N of force on a surface that has an area of 2.0 meter square.

Put F= 140 N and A= 2 meter square in the above expression.

[tex]P= \frac{140}{2}[/tex]

[tex]P= 70 N/m^2[/tex]

Therefore, the pressure exerts on the object is 70 N/m^2.

The motion of air particles inside an inflated balloons:

In the inflated balloons, the molecules of air are far apart. These molecules are in random motion. They collide each other inside the surface of the balloons. The pressure will be exerted by the air molecules on the surface of the balloons. The pressure caused by atmospheric molecules collides with the outside the surface is equal to the pressure caused by atmospheric molecules collides with inside the surface of the inflated balloons. Therefore, the volume of the balloons remains constant.

Answer:

400ft

Step-by-step explanation:

The elevation of Waikapu, Hawaii is 400 feet, and the elevation of Denver, Colorado is 5200 feet, derived from a simple algebraic equation based on their given relationship and sum of elevations.

We are given that the elevation of Denver, Colorado is 13 times greater than that of Waikapu, Hawaii, and the sum of their elevations is 5600 ft. To find the elevation of each city, we can set up a system of equations.

Let x represent the elevation of Waikapu, then the elevation of Denver is 13x. According to the problem, we can set up the equation as follows:

x + 13x = 5600

Combining like terms gives us:

14x = 5600

Dividing both sides by 14 to isolate x gives us:

x = 5600 / 14

x = 400

Now that we have the elevation of Waikapu, we can find Denver's elevation by multiplying 400 by 13:

Denver's elevation = 13 x 400 = 5200 ft

Therefore, the elevation of Waikapu, Hawaii is 400 feet, and the elevation of Denver, Colorado is 5200 feet.

The answer is C: systematic sampling

Answer:

The awnser is C

Step-by-step explanation:

Horace need to buys 2.5 pounds of blueberries

1 pounds = 16 ounces, therefore,

3 pounds = 48 ounces (we multiply 16 and 3 = 48)

To find how many pounds he need to by = 3 ounces – [tex]\frac{2}{4}[/tex]

= 3 – [tex]\frac{2}{4}[/tex]

= [tex]\frac{3}{1}[/tex] – [tex]\frac{2}{4}[/tex] (4 is the smallest number can divide both denominator) therefore, we have

= (4 x 3) – (1 x 2) / 4

=  12 - 2 / 4

= [tex]\frac{10}{4}[/tex]

= 2.5

Thus, Horace buys 2.5 pounds of blueberries.

Step-by-step explanation:

The date set with the greater range is neither as the range is the same.

The median is not the same for both sets of data.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

Number of boys = 10

The number of hours from the 10 boys.

= 8, 10, 10, 10, 12, 13, 14, 15, 15, 20

Range = Highest value - Lowest value

= 20 - 8

= 12

Median = (12 + 13)/2 = 25/2 = 12.5

Number of girls = 10

The number of hours from the 10 girls.

= 3, 4, 4, 4, 6, 7, 8, 10, 10, 15

Range = Highest value - Lowest value

= 15 - 3

= 12

Median = (7 + 8)/2 = 15/2 = 7.5

Thus,

The range of both boys and girls is the same.

The median of boy's number of hours is 12.5.

The median of girl's number of hours is 7.5.

Final answer:

Fiona needs to mow at least 9 lawns to earn at least $135, represented by the inequality 15L ≥ 135, where L is the number of lawns mowed.

Explanation:

To determine how many lawns Fiona must mow to earn at least $135, we can set up an inequality. Fiona earns $15 for each lawn she mows, therefore if we let L represent the number of lawns mowed, then Fiona's earnings can be represented by 15L. She needs to earn at least $135, so we can write the inequality as 15L ≥ 135. To find L, we divide both sides of the inequality by 15, which gives us L ≥ 9. Therefore, Fiona must mow at least 9 lawns to earn at least $135.

The probability that she will not spin a 4 will be 0.80 or 4/5.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Sandy spun a spinner with 5 equal parts labeled 1-5. Then the total number of events will be given as,

Total events = 5 {1, 2, 3, 4, 5}

Then the favorable events are given as,

Favorable events = 4 {1, 2, 3, 5}

Then the probability is given as,

P = 4 / 5

P = 0.80

The probability that she will not spin a 4 will be 0.80 or 4/5.

Final answer:

The probability that Sandy will not spin a 4 on a spinner with 5 equal parts is 4/5 or 80%. There are 4 favorable outcomes and 5 possible outcomes in total.

Explanation:

The question asks for the probability that Sandy will not spin a 4 on a spinner that's divided into 5 equal parts, each labeled with the numbers 1-5. Since there are 5 outcomes and only one of them is the one we want to avoid, that leaves us with 4 favorable outcomes (spinning a 1, 2, 3, or 5). The probability of not spinning a 4 is therefore the number of favorable outcomes (not spinning a 4) divided by the total number of possible outcomes (spinning any number from 1 to 5).

To calculate this, we divide the favorable outcomes by the total number of outcomes. This gives us a probability of 4/5, or 80%. The calculation is as follows:

Therefore, P(not spinning a 4) = 4 favorable outcomes / 5 total outcomes = 4/5 or 0.8, which means there is an 80% chance that Sandy will not spin a 4.

Answer:

Balance = $367.5

Step-by-step explanation:

The 2.5% of $350 is,

→ (350/100) × 2.5

→ 3.5 × 2.5

→ $8.75

The balance after 2 years is,

→ $350 + (2.5%) × 2 years

→ 350 + 8.75 × 2

→ 350 + 17.5

→ $367.5

Hence, the answer is $367.5.

The balance after 2 years on principle amount of $350 at the rate of 2.5% will be $525.

The simple interest method, which adds interest to the starting principal amount at the same rate every day, is a quick and easy technique to calculate the interest on that money.

Simple interest is a way to calculate the amount of interest that will be charged on a certain amount of money at a certain rate and for a certain period of time.

As per the information in the question,

Principle amount, p = $350

Rate, r = 2.5%

Time, t = 2 years.

Use the formula of simple interest,

[tex]S.I = (p*r*t)/100[/tex]

S.I = (350 × 2.5 × 2)/100

S.I = 17500/100

S.I = 175

Now, the total amount will be,

$350 + 175 = $525

Answer : The sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]

Step-by-step explanation :

The general formula to calculate the term of binomial expression is:

[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]

where,

(r+1) = number of term

As we are given the binomial expression :

[tex](5y+3)^{10}[/tex]

For sixth term :

a = 5y

b = 3

n = 10

As, r + 1 = 6

So, r = 6 - 1

r = 5

Now put all the given values in the above formula, we get:

[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]

[tex]T_(5)=^{10}C_5a^{10-5}b^5[/tex]

[tex]T_(5)=^{10}C_5a^{5}b^{5}[/tex]

Thus, the sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]
