A traffic sign casts a shadow 7m long at the same time a person 1.6m tall casts a shadow 4m long. Find the height of the sign.​

Answers

height of sign = x

length of sign shadow = 7m

For sign:-

[tex]tan \theta = \frac{p}{b} = \frac{height}{shadow} = \frac{x }{7} [/tex]

height of man = 1.6m

length of man shadow= 4m

For man :-

[tex] \tan\theta = \frac{p}{b} = \frac{height}{shadow} = \frac{1.6}{4} [/tex]

tanθ is same bez sun is at same level (angle) for both of them

So according to questions :-

[tex] \tan( \theta) = \frac{x}{7} = \frac{1.6}{4} \\ \frac{x}{7} = \frac{ \cancel{1.6}^{ \: \: 0.4} }{ \cancel4} \\ x = 7 \times 0.4 \\ x = 2.8m \: [/tex]

so we can say height of the sign = x = 2.8 m

What is the inverse of the conditional statement?

If a polygon has five angles, then it is a pentagon.

If a polygon is a pentagon, then it has five angles.
If a polygon is not a pentagon, then it does not have five angles.
If a polygon does not have five angles, then it is not a pentagon.
If a polygon has five angles, then it is not a pentagon.

Answers

(A.) If a polygon is a pentagon, then it has five angles.

The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

Option C is the correct answer.

What is a pentagon?

A pentagon is a polygon that has five sides and five angles.

The sides and angles of a pentagon are not all equal unless it is a regular pentagon.

A regular pentagon has five equal sides and five equal angles.

We have,

The inverse of a conditional statement is formed by negating both the hypothesis and the conclusion.

In this case, we negate the statement "a polygon has five angles" to "a polygon does not have five angles," and negate the statement "it is a pentagon" to "it is not a pentagon."

Thus,

The inverse of the conditional statement "If a polygon has five angles, then it is a pentagon" is "If a polygon does not have five angles, then it is not a pentagon."

A cell phone plan charges a base fee of $65 and an overage charge of $30 per gigabyte of data that exceed 2 gigabytes. If C represents the cost and G represents the total amount of gigabytes of data. What equation could represents this plan when more than 2 gigabytes are used

Answers

Answer:C =$65 + $30G

Step-by-step explanation:

Given that :

Base fee charge = $65

Overage charge = $30 / per gigabyte for data that exceeds 2 gigabyte

C = cost ; G = total amount of gigabyte

Equation to represent plan; if more than 2 gigabyte are used :

Cost (C) = Base charge + (average charge * amount of gigabyte)

C = $65 + ($30 * G)

C =$65 + $30G

The line parallel to line B has a slope of

Answers

Convert to x in terms of y.

3x + 6y = 12

Divide by 3.

x + 3y = 4

Subtract x.

3y = -x + 4

Divide by 3.

y = (-1/3)x + 4

The slope is -1/3 here. A parallel line would have the same slope.

So the slope of the parallel line is -1/3

Keisha's fish tank has 13 liters of water in it. She plans to add 4 liters per minute until the tank has at least 41 liters. What are the possible numbers of minutes Keisha could add water? Use t for the number of minutes. Write your answer as an inequality solved for t.

Answers

Answer:

7≥t

Step-by-step explanation:

The tank already has 13litres of water in it.

Keisha plans on increasing the quantity of the water to 41 litres. Hence,

41 litres - 13litres = 28litres

The above implies that she needed 28litres to be added to the fish tank.

She adds 4 litres per minute

Now, the question can now be reframed as how many minutes will be needed to add 28litre.

Considering to proportion method

4litres = 1 minute

28litres = t minutes

4litres × t minutes = 28litres

t = 28/4

t = 7 minutes

Hence, at least 7 minutes will be needed to increase the quantity of the tank water from 13litres to 41litres

But since we are to write the answer in an inequality form.

41≥ 13+4t

Solve for t

41≥13+4t

41-13≥4t

28≥4t

Divide both sides by 4

28/4≥4t/4

7≥t
