To divide fractions, you need to follow these steps:

Flip the second fraction (the one you want to divide by) upside down (this is called taking the reciprocal).

Multiply the first fraction by the reciprocal of the second fraction.

Simplify the resulting fraction if possible.

Here is an example:

1/3 ÷ 2/5

Step 1: Flip the second fraction: 2/5 becomes 5/2.

Step 2: Multiply the first fraction by the reciprocal of the second fraction: 1/3 x 5/2 = 5/6.

Step 3: Simplify the resulting fraction if possible: 5/6 is already in its simplest form.

Step-by-step explanation:

All the sides of a rhombus are the same. Therefore, if you want to find AD its the same as AB which is 6

The length BC of the bisected line segment is: 11.5

Usually a line that bisects a segment usually divides that segment into two equal parts.

Now, we are told that DE bisects Line AC at point B where AB = 3a + 4.

Thus, from the idea of a bisected segment, we can easily say that:

2(3a + 4) = a + 23

6a + 8 = a + 23

6a - a = 23 - 8

6a = 15

a = 15/6

a = 5/2

a = 2.5

Thus:

AB = BC = 3(2.5) + 4

BC = 11.5

This question is incomplete, the complete question is;

Your friend Mona claims that the average student debt immediately after graduation in the United States is $24,500. You want to see if your university has lower student debt at graduation. To test this, you randomly collect data from 40 students who recently graduated. The average of your sample is $22,413, with an associated standard deviation of $7,312. Using this data to perform the hypothesis test; H₀ : μ = 24,500 vs Hₐ : μ < 24,500.

What is the p-value of this test and conclusion at ∝ = 0.05  

Answer:

a) p-value = 0.0394

b) Since p value ( 0.0394 ) is less than ∝ ( 0.05 ), We reject the null hypothesis.

Hence, There is insufficient evidence at ∝ = 0.05 to claim that  the average student debt immediately after graduation in the United States is $24,500.

Step-by-step explanation:

Given the data in the question;

sample size n = 40

sample mean x' = 22413

level of significance ∝ = 0.05

standard deviation s = 7312

Hypothesis;

Null Hypothesis             H₀ : μ = 24,500

Alternative Hypothesis Hₐ : μ < 24,500

Test Statistics;

t = (x' - μ) / ( s/√n)

we substitute

t = (22413 - 24500) / ( 7312 / √40)

t = -2087 / 1156.1287

t = -1.805

Degree of Freedom DF = n - 1 = 40 - 1 = 39

With t = -1.8052 and df = 39

p( t < -1.805 ) = 0.0394

p-value = 0.0394

Since p value ( 0.0394 ) is less than ∝ ( 0.05 ), We reject the null hypothesis.

Hence, There is insufficient evidence at ∝ = 0.05 to claim that  the average student debt immediately after graduation in the United States is $24,500.

a) The simplified ratio is 2:7.

b) 70 machines would pack approximately 245 crates of apples per day.

a) The ratio of the number of machines to the number of crates packed per day can be calculated by dividing the number of machines by the number of crates packed. In this case, there are 40 machines packing 140 crates per day. Thus, the ratio can be expressed as:

40:140

However, we can simplify this ratio by dividing both numbers by their greatest common divisor, which is 20:

40 ÷ 20 : 140 ÷ 20

2:7

So, the simplified ratio is 2:7.

b) If 40 machines pack 140 crates per day, we can use this information to determine how many crates 70 machines would pack. We can set up a proportion to solve for the unknown value:

40 machines / 140 crates = 70 machines / x crates

To solve for x, we can cross-multiply:

40 * x = 140 * 70

Dividing both sides by 40:

x = (140 * 70) / 40

x ≈ 245 crates

Therefore, 70 machines would pack approximately 245 crates of apples per day.

Answer:

70

Step-by-step explanation:

Step-by-step explanation:

there are several formulas that could play a role.

but in our case, where we have velocities and the deceleration, we are going to use

fV = iV + at

fV = final velocity (0 on our case)

iV = initial velocity (40 m/s in our case)

a = acceleration (-15 m/s² in our case)

t is the time it takes to reach fV.

0 = 40 + (-15)t = 40 - 15t

15t = 40

3t = 8

t = 8/3 = 2.666666666... seconds

so, it takes 2.6666666... or 2 2/3 seconds to bring the vehicle to a standstill.

To graph this equation, start at the origin (0,0) since there is not y-intercept.

Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.

Because the rise (up and down, numerator) is 1, we know that we will go up one unit.

The run (side to side, denominator) is 4, so we will go to the right 4 units.

This makes the first point (4, 1).

Step-by-step explanation:

The correct answer is true. If you know that the relationship between quantities is proportional, you can use proportions to find missing quantities.

Step-by-step explanation:

N = 50 000   and  N = 1000 * 2^t

so

50 000 = 1000 2^t      divide both sides of the equation by 1000

50 = 2^t      LOG both sides

log 50 = t log 2

log 50 / log 2 = t = 5.64 hours

We have

0 < π/12 < π/2

and

tan(π/12) = sin(π/12) / cos(π/12)

Both sin(x) and cos(x) are positive for 0 < x < π/2, so we expect tan(π/12) to also be positive.

Recall the double-angle identities for cosine,

cos²(x) = (1 + cos(2x)) / 2

as well as the Pythagorean identity,

tan²(x) = sec²(x) - 1

and by definition,

sec(x) = 1 / cos(x)

Putting everything together, we have

tan(x) = √(1 / cos²(x) - 1)

tan(x) = √(2 / (1 + cos(2x)) - 1)

Let x = π/12. Then 2x = π/6, and cos(π/6) = √3 / 2, so that

tan(π/12) = √(2 / (1 + cos(π/6)) - 1)

tan(π/12) = √(2 / (1 + √3 / 2) - 1)

tan(π/12) = √(4 / (2 + √3) - 1)

tan(π/12) = √(4 / (2 + √3) - (2 + √3) / (2 + √3))

tan(π/12) = √((2 - √3) / (2 + √3))

tan(π/12) = √(7 - 4 √3)

Step-by-step explanation:

similar triangles.

each triangle is created by the object height, its shadow length, and the invisible distance between the top of the object and the end of the shadow.

in similar triangles the angles in both triangles are the same. and the ratio of sidelights of a pair of corresponding sides in both triangles is the same for every pair of corresponding sides.

so the ratio of the shadows of both objects must be the same as the ratio of the height of both objects.

36.4 / 1.15 = height / 2.8

height = 36.4 × 2.8 / 1.15 = 101.92 / 1.15 = 88.62608696...

so, rounded, the building is 89 meters tall.
