In the measurement of the length of a cylinder, the main scale reading of a vernier caliper is 2.8 cm, the vernier reading is 4, and the least count of the vernier is 0.01 cm. Find the reading of the length of the cylinder.

Answers

Answer 1

Answer:

the reading of the length of the cylinder is 2.84 cm

Step-by-step explanation:

Given the data in the question;

the main scale reading = 2.8 cm

the Vernier reading = 4

the least count of the Vernier = 0.01 cm

the reading of the length of the cylinder = ?

To determine the reading of the length of the cylinder, we simply say;

Reading length = main scale reading + ( Vernier reading × least count )

so we substitute in our given values

Reading length = 2.8 cm + ( 4 × 0.01 cm )

Reading length = 2.8 cm + 0.04 cm

Reading length = 2.84 cm

Therefore, the reading of the length of the cylinder is 2.84 cm

If I had 4 eggs
A thief gave me 3 eggs

How many eggs do I have?

Answers

8 because it says you HAD 4 eggs, you don’t have them anymore

Using basic operations, it is found that you have 12 eggs.

----------------------------------

Initially, you had 4 eggs.When the thief gave you 3 eggs, these 3 eggs were added to your amount, thus, you had 4 + 3 = 7 eggs.When the farm rooster laid 5 eggs, these 5 eggs were added to your amount, thus, at the end, you ended up having 7 + 5 = 12 eggs.

C. If the team does not win the game, then the team will not advance to the playoffs.
D. If the basketball player makes the shot, then the team will advance to the playoffs.

Answers

Answer:

if the basketball player makes the shot, then the team will advance to the playoffs (option d)

Explanation:

statement a is incorrect because the reverse of a statement is not always true. for example, all girls are humans but not all humans are girls. as such, we do not know that if the basketball player does not make the shot, the team will not win the game.

statement b is also incorrect, and uses a similar line of reasoning as statement a.

statement c is incorrect as well, and also uses the same reasoning as statements a and b.

statement d is correct. the reasoning used here is that if [x], then [y]. if [y], then [z]. thus, if [x], then [z].

What is the reference angle for the angle with the measure 2x/3

Answers

The reference angle for the angle with the measure 2x/3 is 54⁰

How to determine the reference angle?

You should understand that a reference angle is the acute angle to a given angle.

The given angle is 2x/3

We should understand that since the angle has the variable x

= x + 2x/3 = 90⁰

Simplifying the fraction to have

(3x+2x)/3 = 90

Cross and multiply we have 5x=270⁰

Making x the subject

x= 270/5

x=54⁰

Therefore, the reference angle with the measure 2x/3 is = 54⁰

1ei. (x-4)(x+1)>0

Answers

Answer:

1ai. x is less than or equal to 8

1ei. x > 4 and x > 1

Step-by-step explanation:

Steps for solving 1ai

Factor x² less then or equal to 8 you would do this by finding two numbers the product is equal to zero and the sum would equal to zero. You would find all factors that would equal to your terms like for example x² has the factors x•x and the factors of 0 are 0 so it would be (x+0)(x+0) is less than or equal to 8Split the factoed terms into two inequalities since you're dealing with polynomial inequalities you will either have one or more solutions. For example you will have to solve x + 0 is less than or equal to 8 Solve for x by doing the inverse operation in this case the addition will become subtraction so it will be x + 0-0 is less than or equal to 8 - 0 which would be x is greater than or equal to 8

Steps to solve 1ei

Split the factored terms into 2 inequalities so (x-4) (x+1) >0 will become x-4>0 and x+1>0 Solve for x in this case x-4>0 will become x-4+4> 0+4 which is x>4 and x+1>0 will be x+1-1>0-1 which is x>-1

The maximum number of poles required to drive the load is 8.

full load speed = 120*f/p

since no. of poles are even so

p = 8

if number pole p = 8

Let (-3, 4) be a point on the terminal side of 0. Find the exact values of sin 0, csc 0, and cot 0.

Answers

Therefore, sin θ = 4/5, csc θ = 5/4, and cot θ = -3/4 using trigonometric ratio.

Trigonometric ratio calculation.

We know that the point (-3, 4) is on the terminal side of the angle θ, and we can use the Pythagorean theorem to find the value of the hypotenuse:

r² = x² + y²

r² = (-3)² + 4²

r² = 9 + 16

r² = 25

r = 5

Now we can find the values of sin θ, csc θ, and cot θ:

sin θ = y/r = 4/5

csc θ = r/y = 5/4

cot θ = x/y = -3/4

Therefore, sin θ = 4/5, csc θ = 5/4, and cot θ = -3/4.

7x + 33 = 180 subtract 33 from both sides
