What is the distance between −3 and 0? I dont know I got confused

Answers

Answer:

The distance between -3 and 0 is 3.

Step-by-step explanation:

1. First off, draw a number line. Be sure to plot -3 and 0.

2. Count how many numbers are between -3 and 0.

You will see that there is 3.

-3, -2, -1, and then 0.

1, 2, 3 distances apart.

The answer is 3 because the length from 0 to -3 would be 3.

Which expressions are equivalent to 4(9+3)?

a
4(12)
b
36 + 3
c
36 + 12
d
4 + (9 + 3)
e
(9 + 3) + (9 + 3) + (9 + 3) + (9 + 3)

Answers

Answer:

b

Step-by-step explanation:

using the distributive property you get b

I believe the correct answer is C) 36+12

The equation is 4(9+3). Because of the fact that the four is on the outside, you can distribute the it so both the 9 and the 3.

9 x 4=36
4 x 3= 12

After doing this you set up your new equation which is 36 + 12!

That’s how I got this answer, hope it helps lol.

Help Me With Functions Part 4.

Answers

Answer:

for this one, your answer will be B.X

Step-by-step explanation:

It is X because each element in x is mapped to exactly one element in y.

In X 6 maps to 4,2; in y 6 maps to 6,2; in Z 7 maps to 2,8.

so every element in x should map to exactly one element in y and it is possible only in the set X so the answer is X.

Answer:

A.)  x=25

Step-by-step explanation:

since these are vertical angles, that means they equal the same

  -  75= (4x-25)

add 25 to both sides in order to isolate 4x

  -   100=4x

divide both sides by 4 in order to isolate the x

  -    25=x or x=25

Answer:

[tex]\huge\boxed{x = 25}[/tex]

Step-by-step explanation:

In these two lines that intersect, we can see that 4 angles are opposite from each other. This means that they are vertical angles and therefore equal. 2 of these angles have values next to them, which happen to be across from each other.

Based on this, we know that they are equal. If we write this as an equation, we can solve it to find the value of x.

75º = (4x - 25)º

Add 25º to both sides of the equation

100º = 4x

Divide both sides of the equation by 4 to isolate x

x = 25

Here are two patterns made using identical rhombuses. Without using a protractor, determine the value of a and b.

Answers

Answer:

a = 60°

b = 120°

Step-by-step explanation:

First, you can find measure a by using the first shape. There are six rhombuses, and you can use the innermost a of each one to form a circle. A full circle is 360°, so divide 360 by six. The answer is sixty. So on the next shape, the a measurements add up to 120°. Subtract that from the circle: 360 - 120 = 240. And since there are two measurements for b, you would divide 240 by two. The answer is 120.

To check your work, use the knowledge that circles are 360° (the four interior corners of a rhombus will also add up to 360°. 2(120) + 2(60) = 360. Hope this helps! Feel free to ask any questions!

Is the probability of Janessa winning an independent event or dependent event? Why?
A. Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.
B. Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
C. Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.

Answers

Answer:

I know for number 2 its- D. Her probability of winning is an independent event because it depends on the results of her friends’ rolls.

Step-by-step explanation:

ill edit to find the rest of the answers

a) The sample space for Janessa's calculation is [ 5 , 6 ]

b) Her probability of winning is a dependent event because it depends on the results of her friends' rolls.

c) The number of desired outcomes for Janessa's probability is 2.

d) There are 29 possible outcomes

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

a)

Since Janessa needs to roll a number higher than both her friends to win the game, the possible outcomes for her roll are limited to 5 and 6, since these are the only numbers that are higher than 4 and 3. Therefore, the sample space for Janessa's calculation consists of the numbers 5 and 6, which can be written as [5, 6]

b)

The probability of Janessa winning is a dependent event because it depends on the results of her friends' rolls. If one of her friends had rolled a higher number, then the probability of Janessa winning would be 0. Therefore, the outcome of Janessa winning is dependent on the outcomes of her friends' rolls.

Hence , her probability of winning is a dependent event because it depends on the results of her friends' rolls.

c)

Janessa needs to roll a number higher than both friends, and the only numbers that meet this criteria are 5 and 6. Therefore, the number of desired outcomes for Janessa's probability calculation is 2.

d)

There are a total of 8 + 7 + 14 = 29 pens in the bag. When Denato pulls a pen from the bag, there are 29 possible outcomes since he can choose any of the 29 pens in the bag.

Hence , the probabilities are solved

What is the total surface area of the prism below? (Can I pls get the whole problem solved step by step, most of it!)

Answers

Answer:

672

Step-by-step explanation:

Okay so, the surface area of a figure is just all the areas of the faces added together. The front face ( 9x16 ) would be 144. The back face would be 12x9 or 109. The base would be 20x9 or 180. Now, this is where it might get tricky. The triangles will be 12x20x0.5 or 1/2. The answer for that would be 120. Now since there are two, multiply the 120 by two. ( Technically, since there are two of the same triangles you would not need to multiply by 0.5, but just to be safe i'll do it here. )  Finally, add all the areas together. The final answer is 672. Hope this helps!

672 is the answer sorry if wrong
