Which one is correct

Answer:

AB = 26.5º

Step-by-step explanation:

cosA = adj/hyp

cosA = AC/AB

cos41 = 20/AB

Multiply both sides by AB

AB * cos41 = 20

Divide both sides by cos41

AB = 20/cos41

AB = 26.5º

Answer:

Explanation:

ΔABC is right in the angle ∠C

in this case AB is the hypotenuse of the triangle ABC

according to the given data we will use the length of AC which is the adjacent side to the angle ∠A and the Cosine of the angle ∠A in the following formula:

the hypothenuse = adjacent side / cosine of the angle

AB = 20 / cos(41°)

AB = 26.5

Answer:

Jackson is walking an average of 1.5 blocks per minute.

Step-by-step explanation:

6 divided by 4 is 1.5

The speed at Jackson for walking 6 blocks in 4 minutes will be equal to 1.5 blocks per minute.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the instructions provided in the question,

The distance (d) traveled by Jackson = 6 blocks

The time (t) taken to travel 6 blocks by Jackson = 4 minutes

[tex]Speed(s)=\frac{Distance(d)}{Time(t)}[/tex]

Put values in the above equation,

s = 6/4

s = 1.5 blocks per minute.

1) Fill in the Blanks

The First Blank is 1/2 because 1/2 + 1/2 = 1

The Second Blank is 3/4 because 3/4 + 1/4 = 1

The Third Blank is 1/3 because 1/3 + 2/3 = 1

2) Find the LCD

The Least Common Denominator (also known as LCD) is 60

To find this, find the number that each of the denominators can multiply to and have the same one together.

3) Find the length of the final scarf

A full scarf has a length of 150cm

We must use the fragment that is 1/2 this size

150 ÷ 2 = 75

We must use the second fragment which is 3/4 150cm

Divide the scarf into 4 pieces

150 ÷ 4 = 37.5

We need 3 1/4 fragments to = 3/4

37.5 x 3 = 112.5

The final fragment is 1/3 the length of the full scarf

We must divide the scarf into 3 sections

150 ÷ 3 = 50

The three lengths we just found were 75cm, 112.5cm, and 50cm

Add all of the lengths up to find the final length of the last scarf

75 + 112.5 + 50 = 237.5cm

The Final scarf length is 237.5cm

Answer:

x = 4

FE = 8

Step-by-step explanation:

Congruent means equal. Notice how both F and C equal 30 degrees while line AC and line DF are both equal to 9 inches. This means we can equal line CB to line FE to find the value of x:

2x = x + 4

Isolate variable x by subtracting both sides by x:

2x - x = x - x + 4

x = 4

Check your work:

2(4) = 4 + 4

8 = 8

Correct

Answer:

B

Step-by-step explanation:

I believe it is B because it is the only one that doesnt have x values that repeat and give different answers.

Ex. For a, the x value in the first and third coords gives both 1 and 3 as answers.

Every x has to have a unique y value, so

(2,10) (3,12) is ok, but (2,10) (2,12) is not.

The value of the inequality is P > -5.

Therefore the correct option is c.

Given is an inequality P - 3 > -8, we need to solve and graph it,

To solve the inequality P - 3 > -8, you can isolate the variable P by adding 3 to both sides of the inequality:

P - 3 + 3 > -8 + 3

Simplifying further:

P > -5

The solution to the inequality is P > -5, which means that P can take any value greater than -5.

To graph this solution on a number line, you can represent all values greater than -5 with an open circle on -5, and shade the region to the right of -5 to indicate the values that satisfy the inequality. Since the inequality does not include -5 itself (due to the strict inequality P > -5), the circle representing -5 should be left open.

Here's a visual representation of the graph (attached)

The shaded portion on the number line represents the values of P that satisfy the inequality P > -5.

Hence the value of the inequality is P > -5.

The sequence of transformations that maps the congruent figures are

Rotation, Reflection and Translation.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

The types of transformations that preserve congruency includes: Rotation Turns a figure around a fixed point.

Since Reflection Flip of figure over a line where a mirror image is created.

And Translation Sliding a shape to a new place without changing the figure.

Answer:

Step-by-step explanation:

A correct answer can only be obtained from a complete question.

A rotation is not always about the origin, but in the absence of information, this will be assumed.

Rotating to the right is assumed to mean rotated from the second towards the first quadrant about the origin.

Rotating any shape about the origin by 360° will always return to the original (starting) position, so the final coordinates will be (-8,2) (-8,8) (-4,2).
