Final Answer:

The magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Explanation:

To find the magnitude of the resultant force when two forces are acting at an angle to each other, we can use the law of cosines. In this scenario, we have two forces each of 10 pounds acting on an object with an angle of 135° between them. Let's denote the forces as F1 and F2, both of which have magnitudes of 10 pounds. The angle between them is θ = 135°.

The formula for the resultant force R when two forces act at an angle θ is:

[tex]\[ R = \sqrt{F1^2 + F2^2 + 2 \cdot F1 \cdot F2 \cdot \cos(θ)} \][/tex]

In our case:

[tex]\[ F1 = F2 = 10 \, \text{pounds} \][/tex]

[tex]\[ θ = 135° \][/tex]

Plugging these values into the formula, we get:

[tex]\[ R = \sqrt{10^2 + 10^2 + 2 \cdot 10 \cdot 10 \cdot \cos(135°)} \][/tex]

[tex]\[ R = \sqrt{100 + 100 + 200 \cdot \cos(135°)} \][/tex]

The cosine of 135° is -√2/2 (since 135° is in the second quadrant where the cosine is negative):

[tex]\[ R = \sqrt{200 - 200 \cdot \frac{-\sqrt{2}}{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100\sqrt{2}} \][/tex]

[tex]\[ R = \sqrt{200 + 100 \cdot 1.414} \] (Since √2 is approximately 1.414)[/tex]

[tex]\[ R = \sqrt{200 + 141.4} \][/tex]

[tex]\[ R = \sqrt{341.4} \][/tex]

[tex]\[ R \approx 18.47 \text{ pounds} \][/tex]

Therefore, the magnitude of the resultant force when two 10 pound forces act on the same object 135° apart is approximately 18.47 pounds.

Step-by-step explanation:

120 and 56

The students spent 5% of their $500 budget on props, calculated by dividing $25 by $500 and then multiplying by 100.

To determine the percentage of the total budget that was spent on props for the student film, we need to use the formula for calculating percentages. The formula is
(amount spent / total budget)
* 100 = percentage spent.

Applying this formula to the given values:

Therefore, the students spent 5% of their total budget on props.

(x+4)(x-5)

Step-by-step explanation:

You need to find two numbers that multiply to be -20 but add up to be -1.

Answer:

( x - 5 ) ( x + 4 )

Step-by-step explanation:

When solving quadratic equations it's important to remember that they have 2 solution. We need to work out the factors, sum and the products to successfully factorise the quadratic and solve it. So,

x² - x - 20 = 0

Sum = -1

Product = -20

So we need two numbers that sum to -1 and multiply together to make -20

Factors = -5 and 4

x² - 5x + 4x - 20

Factor x² - 5x and 4x -20 separately

x² - 5x = x ( x - 5 )

4x - 20 = 4 ( x - 5 ) So

x ( x - 5 ) + 4 ( x - 5 )

We can see a common factor of  ( x - 5 ) and the other bracket would be       ( x + 4)

( x - 5 ) ( x + 4 )

Answer:

0.8 kilograms of fertilizer

Step-by-step explanation:

Looking at the data given to us in a fraction form, we can imagine:

4 kilograms / 5 weeks

To find out how many kilograms of fertilizer was used each week, we're going to divide that fraction out, so we're going to do 4 divided by 5. Dividing this will give you:

0.8 kilograms

Therefore your answer is that they use .8 kilograms of fertilizer each week.

Here is what the equation should look like when replaced with the numbers (it will be a fraction) :

                                     [tex]\frac{8 - (-20)}{5 - 3}[/tex]

We know that two negatives cancel out and make a positive, so the numerator would actually be 8 + 20.

Answer:

There will be $2288.98 in the account after 6 years

Step-by-step explanation:

We are given that $1750 is put into an account that pays an annual rate of 4.5%  compounded quarterly.

So, Principal = $1750

Rate of interest = 4.5%

No. of compounds per year = 4

Time = 6 years

Formula :[tex]A =P(1+\frac{r}{n})^{nt}[/tex]

Where A = Amount

P = Principal

r = rate of interest

n = no. of compounds per year

t = time

Substitute the values in the formula :

[tex]A =1750(1+\frac{4.5}{400})^{4 \times 6}[/tex]

A=2288.98

Hence There will be $2288.98 in the account after 6 years

Final answer:

To find the numbers Ali picked, we identify the lowest number (11), calculate the highest number using the range (11 + 13 = 24), and confirm that the median (17) fits between these two numbers. Thus, the numbers are 11, 17, and 24.

Explanation:

Ali picked three numbers, and we have been provided with three pieces of information about these numbers: the lowest number was 11, the range was 13, and the median was 17. We can use this information to determine the three numbers Ali picked.

Step 1: Identify the Lowest Number

We know the lowest number is 11. This is our starting point.

Step 2: Determine the Range

The range of a set of numbers is the difference between the highest and the lowest numbers. Since the range is 13, we add this to the lowest number to find the highest number: 11 + 13 = 24. So, the highest number Ali picked is 24.

Step 3: Find the Median

The median is the middle number in a set of numbers that has been arranged in order. We are told the median is 17, which fits perfectly between our lowest and highest numbers, confirming that our calculations are correct.

Therefore, the numbers Ali picked, in order from lowest to highest, are: 11, 17, and 24.

Question;

1) The shaded plants set has greater variability because more data is clustered around the median.

2) The sets are equally variable because the ranges of the data sets are equal.

3) The full sun plants set has greater variability because the IQR for full sun plants is greater.

Answer:

The correct option is;

3) The full sun plants set has greater variability because the IQR for full sun plants is greater

Step-by-step explanation:

To answer the question, we present the dot plot as follows;

Heights of Shaded plants (inches)

          0       4      3       2      0       0             1

0       1.5      2     2.5     3     3.5     4           4.5

We calculate the five numbers as follows;

Max = 4.5

Min = 2

1st quartile = (10+1)/4 th term = 2

2nd quartile (Median) = (10+1)/2 th term = 2.5

3rd quartile = 3×(10+1)/4 th term = 3

Interquatile range (IQR) = Q₃ - Q₁ = 3 - 2 = 1

Where:

Q₁ = 1st quartile

Q₃ = 3rd quartile

Heights of Full Sun plants

0     1      0      2      0       4         3

1.5   2    2.5    3     3.5     4        4.5

We calculate the five numbers as follows;

Max = 4.5

Min = 2

1st quartile = (10+1)/4 th term = 3

2nd quartile (Median) = (10+1)/2 th term = 4

3rd quartile = 3×(10+1)/4 th term = 4.5

Interquatile range (IQR) = Q₃ - Q₁ = 4.5 - 3 = 1.5

The interquartile range, IQR, is a measure of variability

Therefore, the full sun plants set has greater variability because the IQR for full sun plants is greater.

Answer:

the and should be step 3

Step-by-step explanation:

Answer:

The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.

I guess that we want to find the expected value in one spin:

number 1: wins $1

number 2: wins $3

number 3: wins $5

number 4: wins $7

number 5: losses $8

number 6: loses $8

The expected value can be calculated as:

Ev = ∑xₙpₙ

where xₙ is the event and pₙ is the probability.

We know that the probability for all the events is 1/6, so we have:

Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0

So the expected value of this game is $0, wich implies that is a fair game.

The question is a probability problem in Mathematics. It requires calculating the expected value of a game based on the potential winnings and losses and their respective probabilities. On average, Ivanna will lose a dollar each time she plays.

The subject matter of this question is a probability problem within Mathematics. One way to approach the problem would be to calculate the expected value of Ivanna's winnings from a single spin of the spinner. Each outcome (1, 2, 3, 4, 5, 6) has an equal chance of being chosen, which is 1/6, because there are 6 equally likely outcomes.

The formula for the expected value is the sum of all potential outcomes multiplied by their respective probabilities. Numerically, this would be (1*$1 + 1*$3 + 1*$5 + 1*$7 - 2*$8) / 6, which equals -$1.

Therefore, on average, Ivanna will lose a dollar each time she plays this game.

We have been given that a cone has a radius of 12 inches and slant height of 20 inches. We are asked to find the volume of the cone.

We will use volume of cone formula to solve our given problem.

[tex]V=\frac{1}{3}\pi r^2\sqrt{l^2-r^2}[/tex], where

V = Volume of cone,

r = Radius,

l = Slant height.

Upon substituting our given values in volume formula, we will get:

[tex]V=\frac{1}{3}\pi\cdot 12^2\cdot \sqrt{20^2-12^2}[/tex]

[tex]V=\frac{1}{3}\pi\cdot 144\cdot \sqrt{400-144}[/tex]

[tex]V=48\pi\cdot\sqrt{256}[/tex]

[tex]V=48\pi\cdot16[/tex]

[tex]V=2412.743157[/tex]

[tex]V\approx 2412.74[/tex]

Therefore, the volume of the cone is approximately 2412.74 cubic inches.
