A 45 foot ladders leaning up against a building. The base of the latter is 20 feet away from the building. What is the angle of

Tatiana [17]

Answer:

The angle of elevation to the top of the building is 63.61 degrees

Step-by-step explanation:

Here, we want to calculate angle of elevation to the top of the building.

For this, we need a triangle

Please check for this in the attachment.

From the diagram, we are to calculate the angle theta.

To do this, we use trigonometric identities.

Looking at what we have, we have the hypotenuse and the adjacent.

So the trigonometric identity to use is the cosine

Mathematically Cosine theta = adjacent/hypotenuse

Thus, Cos theta = 20/45

Cos theta = 0.444444444444444

Theta = Arc cos(0.444444444444444)

Theta = 63.61 degrees

The hands of a clock suggest an angle whose measure is continually changing. How many degrees does a minute hand move through du

katen-ka-za [31]

Step-by-step explanation:

oh, come one ! you can literally see that one ...

a full rotation on a clock is a full circle and stands therefore for 360°.

for the minute hand these 360° represent 60 minutes.

4 minutes of 60 is a fraction, a ratio, and the same ratio applies then also to 360°.

4/60 = 1/15

360 × 1/15 = 24°

so, 4 minutes represent 24°.

A company loses $780 as a result of shipping delay the 6 owners of the company must share the loss equally.

tekilochka [14]

A) Change in profit for each owner = -780/8

B) Change in profit for each owner = -$130

The total loss = $780

Number of owners = 6

The 6 owners must share the loss equally

The change in profit for each owner will be the original profit less 780/6

That is -780/6

Evaluating -780/6

Change in profit for each owner = -$130

Of all sixth graders, 70% sent a text message yesterday. Ten trials of a simulation are conducted and the data are recorded belo

Effectus [21]

Answer:

80%

Step-by-step explanation:

According to the given data, the numbers 0 through 6 represent students who sent a text yesterday while the numbers 7 through 9 represent students who did not send a text yesterday.

Based on this key, we will calculate the number of students who sent the text yesterday and the number of students who did not sent the text yesterday.

The given data is: 62072, 34570, 80983, 04292, 83150, 36330, 96268, 14077, 77985, 13511

For each group we will identify how many students sent the text and how many students did not. According to the key, a number from 0 to 6 will be counted as a student who sent the text and a number from 7 to 9 will be counted as a student who did not send the text. Students who did not sent the text are made bold in the groups below.

62072: 4 students sent the text, 1 did not

34570: 4 students sent the text, 1 did not

80983: 2 students sent the text, 3 did not

04292: 4 students sent the text, 1 did not

83150: 4 students sent the text, 1 did not

36330: All 5 students sent the text

96268: 3 students sent the text, 2 did not

14077: 3 students sent the text, 2 did not

77985: 1 student sent the text, 4 did not

13511: All 5 students sent the text

We need to find the probability that 3 or more of a group of 5 students randomly selected will send a text today.

From the given groups, the number of groups where 3 or more students sent a text = 8

This represents our number of favorable or desired outcomes.

Total number of possible outcomes is the total number of groups = 10

Since, probability is defined as the ratio of number of favorable outcomes to total number of outcomes, based on the simulated data the probability that 3 or more of a group of 5 students randomly selected will send a text today will be = $\frac{8}{10}=0.80=80\%$

Thus, based on the simulated data there is 80% probability that 3 or more of a group of 5 students randomly selected will send a text today
