Mr. Baker moves 2 meters per second while standing on the moving sidewalk, and he walked 20 meters to get to the moving sidewalk. which is the correct answer would be an option (C).

Distance is defined as the product of speed and time.

The function shows Mr. Baker's distance (d), in meters, from the check-in counter while he has been standing on the moving sidewalk for s seconds. d = 2s + 20.

Here He travels at a speed of two meters per second while standing on the moving sidewalk, and he walked 20 meters to get there.

Thus, Mr. Baker moves 2 meters per second while standing on the moving sidewalk, and he walked 20 meters to get to the moving sidewalk.

Hence, the correct answer would be option (C).

The Solution to the trigonometry expression is 1/2

Trigonometry expression

A trigonometric expression is one that contains a trigonometric function with a variable. It can also be in terms of the sine and cosine functions.

cos75°cos15° + sin75°sin15°

Using the relation  Cos (θ) = Sin( 90° - θ)

Sin (θ) = cos (90° - θ)

Sin ( 2θ) = 2 sin θ cos θ

So:

cos75° cos15° + sin75° sin15° = Sin 15° cos 15°  +  Sin 15°  cos 15°

Sin 15° = 1/2

Therefore, the expression cos75°cos15° + sin75°sin15° = 1/2.

The confidence is 66%. We are 66% confident that the mean score for the students is in the given interval

Given: standard deviation(s) = 16, number of sample(n) = 110, margin of error(E) = 1.471

E = z x s /√n where z is z-score

1.47 = (z x 16)/√110

z = (1.471x√110)/16 = 0.96

Use the z-score to check the value of p in the table for Area under normal curve (image attached) to determine:

p(-0.96 < z< -0.96)

The value shows that about 66.3% of area under the curve is between -0.96 and 0.96

Therefore, confidence level is 66%. So we are 66% confident that the mean score for all students taking the exam is in the interval

The following properties of equality are used to solve the given equation:

division property, multiplication property, addition property, Subtraction Property, distributive property

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

Equation:

2((2/5) x+8)=4(14-(1/5)x)

1. The division property of equality states that if both sides of an equation are divided by a common real number that is not equal to 0, the quotients remain equal .

2((2/5) x+8)/2=4(14-(1/5)x)/2

(2/5) x+8=2(14-(1/5)x)

2. multiplying a quantity by the sum of two or more terms is the same as adding together the products of the original quantity and each term

(2/5) x+8=28-(2/5) x

3. when the same quantity is added to both sides of an equation, it produces an equivalent equation

(2/5) x +(2/5) x+8=(2/5) x+28-(2/5) x = 28

4. The Subtraction Property of Equality states that an equal value subtracted or removed from two equal items will result in a new equal amount

(4x)/5+8-8=28-8=20

5. The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.

*5(4x)/5= 20*5

4x=100

6.  The division property of equality states that if both sides of an equation are divided by a common real number that is not equal to 0, the quotients remain equal .

The volume of the cylinder is the extension of the base area throughout its length thus the volume of the given cylinder will be 198.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of the cuboid = length × height × width.

As per the given cylinder,

The radius of the base of the cylinder = 3

Height = 7

Base area = π(radius)²

Base area = π(3)²

Base area = 9π

The volume of the cylinder = Base area × Height

Volume = 9π × 7 = 198.

To prove both triangle similar ratio of their sides must be equal

AC/GI = BC/HI

Therefore last option is correct .

The difference between congruence and similarity can be examined mathematically. These two words are defined by  shape, proportion, and angle.

Congruent shapes have the same dimensions and overlap when stacked. Two congruent objects have the same size and shape, but different orientations and placements in  space. This doesn't change the fact that they are the same as they have the same physical properties, angles and dimensions.

Similarity means similar but not identical. A shape can be mathematically equivalent in its base form as follows: B. Circles, but different sizes.

The perimeter of the right triangle would be 66.6 cm.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a right triangle with side 19 centimeters and side 20 centimeters.

Using the Pythagoras theorem, we get -

h² = (19 x 19) + (20 x 20)

h² =  761

h = 27.6 cm

The perimeter will be -

P = [h] + [p] + [b]

P = 27.6 + 19 + 20

P = 66.6 centimeters

a) What is the slope of the line parallel to it?

Parallel lines will never intersect, meaning they have equivalent slopes, so the answer to this part is -(6/5).

b) What is the slope of the line perpendicular to it?

Perpendicular lines will intersect, creating a 90-degree angle, meaning all values in the graphs have been flipped. Thus, the slope of any perpendicular line is the negative reciprocal of the given slope (-1/x). The negative reciprocal of -(6/5) is 5/6, so that is the answer.

The sections on the dice are given as

S = {1, 2, 3, 4, 5, 6}

These sections mean that:

n(3) = 1 and n(4) = 1

Recall that:

A be the event that the number rolled is a 3 or a 4.

So, we have

P(A) = P(3) + P(4)

This gives

P(A) = 1/6 + 1/6 = 1/3

Also, we have

Coin = {Head, Tail}

Where

B be the event that a head is flipped.

This means that

The equation is x = 4f - 148 and value of f is 62 degree Fahrenheit.

Given,

In the question:

The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.

The equation x= 4f - 148 relates the number of chirps per minute x and the outside temperature in degrees Fahrenheit f.

Now, According to the question:

Let x = number of Chirps.

f = temperature in Fahrenheit

Equation Connecting the two is

x = 4f -148

When, x = 100

100 = 4f - 148

100 + 148 = 4f

248 = 4f

f = 248/4

f = 62

Hence, The equation is x = 4f - 148 and value of f is 62 degree Fahrenheit.
