Answer:

16 cm

Step-by-step explanation:

4 cm represents 5 km. There is a total length of 20 km, so you do 20/5=4. Since you have to multiply 5 by 4 to get 20, you also multiply 4cm by 4, and you get 16, or the amount of cm that represents 20 km.

Answer:

\(4 \sqrt{5} \)

Hi there!

\(4\sqrt{5}\)

⇒Using the law of radicals

\(\sqrt{a}\) × \(\sqrt{b}\) ⇔ \(\sqrt{ab}\)

⇒ \(\sqrt{80}\)

⇒ \(\sqrt{16} \times 5\)   \(= \sqrt{16}\) × \(\sqrt{5}\) \(= 4\sqrt{5}\)

Total slack is calculated by the late finish minus early finish and the late start minus the early start

Total slack is simply the amount of time taken for a task to be delayed before the project finish date is delayed. It can be positive or negative.

It is calculated as the calculated as the value of the Late Finish minus the Early Finish field, and the Late Start minus the Early Start field.

Total slack = Late finish - early finish + late start - early start

Thus, the total slack is calculated by the late finish minus early finish and the late start minus the early start.

Answer:

y = 5, y = -5

Step-by-step explanation:

In this question, you would have to solve the equation for "y".

Solve:

-3y² = -75

Divide both sides by -3.

y² = 25

Square root both sides to cancel out the exponent.

√y² = √25

y = ±√25

Simplify the square root for both positive and negative terms.

y = 5

y = -5

Your final answer would be y = 5 and y = -5

The number of weeks are 0 1 2 4 7 12

The balances are 24 32 40 56 80 120

The rate of change of the balance of the student's savings account in dollars and cents per week is also referred to as the slope of the graph that can be potted with these values. The formula for slope is expressed as

Slope = (y2 - y1)/(x2 - x1)

y1 and y2 would be consecutive values of the balance

x1 and x2 would be consecutive values of the number of weeks

When x1 = 0, y1 = 24

When x2 = 1, y1 = 32

Slope = (32 - 24)/(1 - 0)

Slope = 8

The rate of change of the balance of the student's savings account in dollars and cents per week is 8 dollars per week. Converting to cents, it would be 800 cents per week

Answer:

the vertex form :

4(x − (-2))² - 64

Step-by-step explanation:

4x²+16x-48

= 4(x² + 4x) - 48

= 4(x² + 4x + 4 - 4) - 48

= 4(x² + 4x + 4) - 4×4 - 48    

= 4(x + 2)² - 16 - 48

= 4(x + 2)² - (16 + 48)

= 4(x + 2)² - 64

= 4(x − (-2))² - 64

Answer:

480,496 liters

Step-by-step explanation:

To calculate the amount of water needed to produce the beef consumed by one person in a more developed country per year, we need to first determine the amount of beef consumed per year and then multiply it by the water required to produce a given amount of beef.

The average person in a more developed country consumes 85 grams of beef per day. To find the annual consumption, we multiply this value by the number of days in a year:

Annual beef consumption = Daily beef consumption * Number of days in a year

Annual beef consumption = 85 grams/day * 365 days/year

Annual beef consumption = 31,025 grams/year

Now, we need to convert the beef consumption from grams to liters of water. It takes 1,750 liters of water to produce 113 grams of beef:

Water required per gram of beef = 1,750 liters / 113 grams

To calculate the total water needed per year, we multiply the water required per gram of beef by the annual beef consumption:

Water needed per year = Water required per gram of beef * Annual beef consumption

Water needed per year = (1,750 liters / 113 grams) * 31,025 grams/year

Calculating this value:

Water needed per year ≈ 480,496 liters/year

Answer:

9 cm

Step-by-step explanation:

Arc length = θ/360 × 2πr

A circle has an arc with a measure of 120 degrees and a lenght of 3π cm. What is the diameter of the circle

Hence,

3π = 120/360 × 2πr

Diameter = 2r

3π = 1/3 × 2πr

Cross Multiply

9π = 2πr

2r = 9π/π

Note that :

Diameter = 2r

Hence,

Diameter = 9 cm

Step-by-step explanation:

Draw a line representing the height of the triangle, and divide it into 2 triangles.

Apply Pythagoras Theorem on one of the smaller triangles first.

\(h = \sqrt{ {36}^{2} - {(36 \div 2)}^{2} } \\ h = \sqrt{ {36}^{2} - {18}^{2} } \\ h = \sqrt{972} \\ h = 31.17691...\)

The solution of the inequality x − y < z is x < z + y.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality,

x − y < z.

To solve for x:

Add y to both sides,

x < z + y

Therefore, the solution is x < z + y.

Answer:

14/5

Step-by-step explanation:

Given data

We have the function

f(x)= (3x+2)/5

We want to find  f(4)

Hence, let us place x= 4 in the function

f(4)= (3(4)+2)/5

f(4)= (12+2)/5

f(4)= (14)/5

f(4)=14/5

Hence f(4)=  14/5

they are all rational..

The variance of a population is less than 5. Null hypothesis reflects the initial presumption or claim that something is true in this case and true option is : σ^2 ≥ 5.

In hypothesis testing, the null hypothesis (H0) represents the assumption or claim that is initially presumed to be true. In this scenario, we are interested in testing whether the variance of the population is less than 5.

The notation σ^2 represents the population variance, and the symbol ≥ denotes "greater than or equal to." Therefore, the correct null hypothesis is that the population variance is greater than or equal to 5 (σ^2 ≥ 5).

The other options listed are not correct for this scenario:

- σ < 5: This alternative hypothesis suggests that the population variance is strictly less than 5, which is not the hypothesis we want to test.

- σ < 25: This alternative hypothesis suggests a different value for the population variance, which is not what we are interested in.

- σ^2 ≥ 25: This alternative hypothesis sets a higher threshold for the population variance, which is not the hypothesis we want to test.

Therefore, the correct null hypothesis is σ^2 ≥ 5, indicating that the population variance is greater than or equal to 5.
