What are the perimeter and area

A. P= 24 in., A = 24 in.?
B. P= 144 in., A = 48 in.2
O
C. P = 24 in., A = 144 in.2
O
D. P= 48 in., A = 144 in.2

Answers

Answer: P = 48 in, A = 144 in.2

Step-by-step explanation: Since a square has equal sides and we know one side length is 12 inches, then all the sides are 12 inches. For perimeter, we add all sides, which would equal 48 and for area, we multiply 2 of the sides, which would be 144.

Maria is 4 ft 2in tall. To find the height of a flagpole, she measured her shadow and the pole's shadow . What is the height h of the flagpole?

Answers

Answer:

25 ft

Step-by-step explanation:

The height of the flagpole, using trigonometric ratio is 25feet.

The tangent of angle C will be the ratio of Maria's height to her shadow.

What is the tangent of an angle?

The tangent of an angle is the ratio of opposite side to the adjacent side.

It is given that,

Her height = 4 ft 2 inch = 25/6 feet

Length of her shadow =10/3 feet

So, tan C = (25/6)/(10/3)

tan C = 5/4

We know that ∠C and  ∠T will be equal

So, tan C = tan T = h/20

5/4 = h/20

h =25

Therefore, The height of the flagpole, using is 25feet.

Two angle measures in a triangle are 47° and 43°. What type of triangle is it?

Also, I just wanted to say that I can only give brainliest if two people answer. Thank you!

Answers

Answer:

Right triangle

Step-by-step explanation:

Answer:

Right triangle

Step-by-step explanation:

To find the third angle, we add the two known angles.

47 + 43 = 90

The sum of all the angles of a triangle is always 180.

Therefore, we subtract 90 from 180 to find the third, unknown angle.

180 - 90 = 90

Because 90 degrees is the third angle, and 90 degrees is a right angle, this is a right triangle.

Darren has traveled
2/3
of his total trip. He has traveled 21 miles so far. How many more miles does he have to travel?

Answers

Answer:

The answer is 7 miles

Step-by-step explanation:

2/3 × 21 = 14

21-14 = 7

The answer is 10.5 miles because if 2/3 is 21 then 1/3 would be half of that which is 10.5 miles, and since there is only 1/3 left of the trip then he has to travel 10.5 more miles

Where does the graph of cosine begin?

Answer:

Step-by-step explanation:

The cosine function is defined for all real numbers. A graph of it can exist on any interval from -∞ to +∞. Since you make the graph, and it is impossible for you to graph x = -∞, the left side of the graph (where it "begins") will be the point you decide to use to start graphing.

The lengths of nails produced in a factory are normally distributed with a mean of 4.95 centimeters and a standard deviation of 0.05 centimeters. Find the two lengths that separate the top 5% and the bottom 5%. These lengths could serve as limits used to identify which nails should be rejected. Round your answer to the nearest hundredth, if necessary.

Answers

Answer:

The length that separates the bottom 5% is of 4.87 centimeters.

The length that separates the top 5% is of 5.03 centimeters.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 4.95 centimeters and a standard deviation of 0.05 centimeters.

This means that [tex]\mu = 4.95, \sigma = 0.05[/tex]

Bottom 5%:

The 5th percentile, which is X when Z has a pvalue of 0.05. So X when Z = -1.645.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.645 = \frac{X - 4.95}{0.05}[/tex]

[tex]X - 4.95 = -1.645*0.05[/tex]

[tex]X = 4.87[/tex]

The length that separates the bottom 5% is of 4.87 centimeters.

Top 5%:

The 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{X - 4.95}{0.05}[/tex]

[tex]X - 4.95 = 1.645*0.05[/tex]

[tex]X = 5.03[/tex]

The length that separates the top 5% is of 5.03 centimeters.
