Ashley painted 1/2 of her bathroom ceiling. Alex painted 1/4 of the ceiling in the school library. Who painted the larger fraction of their ceiling? Use a picture to demonstrate you answer. ​

Answer:

074°

Step-by-step explanation:

the bearing of Y from X is the measure of the angle from the north line (N) at X in a clockwise direction to Y , that is ∠ NXY

∠ NXY = 180° - 106° = 74°

the 3- figure bearing of Y from X is 074°

So

And

sin47=0.73

cos47=0.68

So meanwhile sin is greater so 6sin is also greater

Answer:

Ship 2

Step-by-step explanation:

From inspection of the diagram, the problem has been modeled as a right triangle.  Therefore, to find \(x\) and \(y\), use trigonometric ratios then compare to determine which distance is the smallest.

Trigonometric ratios

\(\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}\)

where:

To find \(x\) use the sine trig ratio:

\(\implies \sf \sin(\theta)=\dfrac{O}{H}\)

\(\implies \sin(47^{\circ})=\dfrac{x}{6}\)

\(\implies x=6 \sin(47^{\circ})\)

\(\implies x=4.39 \: \sf miles \:(2\:dp)\)

To find \(y\) use the cosine trig ratio:

\(\implies \sf \cos(\theta)=\dfrac{A}{H}\)

\(\implies \cos(47^{\circ})=\dfrac{y}{6}\)

\(\implies y=6 \cos(47^{\circ})\)

\(\implies y=4.09 \: \sf miles \: (2 \: dp)\)

As 4.09 < 4.39, ship 2 is currently closer to the coast guard.

By applying the concept of corresponding angles in similar triangles, we were able to establish the value of x as 25 in the given scenario.

In the given problem, we are provided with information about the angles in two similar triangles: triangle ABC and triangle STU. It is stated that angle UTS in triangle STU is 100 degrees, and since corresponding angles of similar triangles are congruent, we can conclude that angle STU is also 100 degrees.

Next, we examine angle BAC in triangle ABC, which is given as 4x. Using the same logic, we know that angle BAC is also congruent to angle STU. Therefore, we can equate the two angles:

angle BAC = angle STU

4x = 100

To find the value of x, we divide both sides of the equation by 4:

x = 100/4

x = 25

Hence, we determine that x is equal to 25. This method allows us to leverage the known information about one triangle to infer the measurements of corresponding angles in the other similar triangle.

Answer: I believe there would be 25 men

Step-by-step explanation: We can see there are 40 women and the ration is 5 (men) to 8 (women)

If we take 40 and divide it by 8 we get 5

so for every 8 women there are 5 men and we do that 5 times

we get: 40 women and 25 men.

Step-by-step explanation:

Follow the 68-95-99.7 rule

The answer is 2 standard deviations

Part 1

The equation is \(y=a(x+8)(x-72)\).

Using the point \((62, -490)\) to solve for \(a\),

\(-490=a(62+8)(62-72) \implies a=\frac{7}{10}\\\\\therefore \boxed{y=\frac{7}{10}(x+8)(x-72)}\)

Part 2

When \(x=-8\), \(y=0\).

When \(x=2\), \(y=-490\).

So, the average rate of change is \(\frac{-490-0}{2-(-8)}=\boxed{-49}\)

Answer:

The first sentence

Step-by-step explanation:

both sentences stay in past tense.

Answer:A

Step-by-step explanation:

Among the answer choices, the one that keeps a consistent verb tense is the following:

A. He jumped out of the airplane and deployed his parachute.

Verb tense refers to when the action takes place. It can refer to the past, the present, or the future.

A sentence has a consistent verb tense when the actions properly refer to the same time.

In other words, if all actions took place in the past, all the verbs in the sentence must be used in the past.

That is why letter A is the correct option. All the verbs, "jumped" and "deployed" are used in the Simple Past tense.

In the other options, there is no consistency.

Answer:

\(\textsf{(a)} \quad \boxed{9a-3}\)

\(\textsf{(b)} \quad \boxed{-9a-3}\)

\(\textsf{(c)} \quad \boxed{-9a+3}\)

Step-by-step explanation:

Given function:

\(f(x) = 9x - 3\)

Part (a)

To find f(a), substitute x = a into the function:

\(\implies f(a)=9a-3\)

Part (b)

To find f(-a), substitute x = -a into the function:

\(\implies f(-a)=-9a-3\)

Part (c)

To find -f(a), first substitute x = a into the function:

\(\implies f(a)=9a-3\)

Then make the function negative:

\(\begin{aligned}\implies -f(a)&=-(9a-3)\\&=-9a+3 \end{aligned}\)

a. In interval notation, Increasing intervals: (12pm, 1pm) U (1pm, 2pm) U (2pm, 3pm). Decreasing intervals: (8am, 9am) U (11am, 12pm). Constant intervals: (9am, 10am) U (10am, 11am)

b. The increase in cost between 12 noon and 3 pm is $2.

c. Yellow Cab has a lower price per 1km than Swift ride at (8am, 9am) (9am, 10am) (2pm 3pm)

Interval notation is used to represent continuous intervals of numbers or values, like ranges on a number line.

The graph shows that from 8-9am, and 11-12pm, the cost from Swift Ride decreases.

We can represent it as (8am, 9am) U (11am, 12pm).

It increases at these times (12pm, 1pm) U (1pm, 2pm) U (2pm, 3pm).

And stays constant at : (9am, 10am) U (10am, 11am)

We simply deduct the 12pm's cost from 3pm's cost.

So, we have

Cost increase = $3.5 - $1.5

Evaluate the difference

Cost increase = $2

Hence, the cost increase is $2

When you plot the points provided for Yellow cab, you'll notice that Yellow Cab has a lower price per 1km than Swift ride at (8am, 9am) (9am, 10am) (2pm 3pm)

Answer:(4,5π/4)

Step-by-step explanation:

Note that the point is on the circle whose radius is labeled 4, so r=4. The angle of the point is 5π4, so θ=5π4. Thus, the polar coordinates are (4,5π4).

The situation is a combination where 5 digit pin codes has no digit which can be repeated.

Assuming no five-digit number can begin with zero, there are 9 possible choices for the first digit. Then there are 10 possible choices for each of the remaining four digits. Therefore, you have 9 x 10 x 10 x 10 x 10 combinations, or 9 x 10^4, which is 90,000 different combinations.

Combinations are based entirely on grouping. Combinations can be used to determine how many different groups that can be created from the available items.

The techniques used to count the number of outcomes that can occur in different circumstances are permutation and combination. Combinations and permutations are also referred to as arrangements and selections, respectively.

After 1 seconds, the speed of the ball's shadow along the ground is equal to 150 ft/s.

Assuming the ball falls a distance given by this expression:

S = 16t²

Also, the height (h) of shadow of the ball 1 sec​ later is given by:

h = 30 - S

Next, we would derive an expression for the ball's shadow:

OX/30 = (20 + XQ)/30 = XQ/h

30XQ = 20h + hXQ

20h = 30XQ - hXQ

20h = (30 - h)XQ

XQ = 20h/(30 - h)

Substituting the value of h, we have:

XQ = 20(30 - S)/(30 - 30 - S)

Substituting the value of S, we have:

XQ = 20(30 - 16t²)/(30 - 30 - 16t²)

XQ = 20(30 - 16t²)/16t²

XQ = (600 - 320t²)/16t²

XQ = 600/16t² - 320t²/16t²

XQ = 600/16t² - 20

Differentiating wrt t, we have:

d(XQ)/dt = 600/16t² - 20

d(XQ)/dt = 600 (-64t/(16t²)²)

d(XQ)/dt = 600 (-64t/256t⁴)

d(XQ)/dt = 600 (-0.5/2t³)

d(XQ)/dt = -300/2t³

The cost of one portion of cauliflower to the nearest cents is 2880 cents

If you buy cauliflower at $1.80 per pound, this can be expressed as;

$1.80 = 1 pound

In order to get the cost of one portion, we need to get the cost of 6 ounces of cauliflower:

1 ounces = 0.0625 pounds

x = 1 pound

0.0625x = 1

x = 1/0.0625

x = 16 pounds

To get the price for 16 pounds

$1.80 = 1 pound

y = 16 pounds

y = 16 * 1.80

y = $28.8

The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.

The Mean is defined as the ratio of sum of numbers present in the data to the total numbers present in the data. Median is defined as the ratio of sum of middle numbers present in the data. Mode is defined as the most recurring number present in the data. Midrange is the ratio of the largest and smallest number in the data to 2.

Let's see how to calculate Mean, Median, Mode and Midrange.

Mean = 13 + 15 + 18 + 18 + 21 / 5

Mean = 85 / 5

Mean = 17

Median = 18 (as it is the middle term of the data)

Mode = 18 (as it is most recurring number)

Midrange = 21 + 13 / 2

Midrange = 34 / 2

Midrange = 17

Therefore, The Mean is 17, Median is 18, Mode is 18 and, Midrange is 17.
