Patrick wants to use a gift certificate to buy some songs and videos
from an online media store.
• Songs (s) cost $1 each.
• Videos (v) cost $2.50 each.
• Patrick has a gift certificate for $25 for the store.
Which inequality represents the number of songs and videos Patrick
can buy using only his gift certificate?

Answers

Answer:

i think songs it might be correct but im not sure

The inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

Let's suppose the number of songs is 's' and number of videos is 'v'

Total cost for songs = $s

Total cost for videos = $2.50v

Patrick has a gift certificate for $25

Then the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is:

s + 2.50v ≤ 25

Thus, the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

Which number produces an irrational number when added to 0.4?
O A. 0.444...
B. 9

Answers

Answer:  C) 3pi

pi is irrational, and so is 3pi

The expression 3pi+0.4 is overall irrational as well.

If x is irrational and y is rational, then x+y is irrational

This is why choice C is the answer.

The other answer choices are rational values which would make the sum rational, so that's why we can rule them out.

Which list gives all the factors of 8? 2, 4, 6, 8 8, 16, 24, 32 1, 3, 5, 7 1, 2, 4, 8

Answers

Answer:

{1,1,2,2,4,4,8,8}

Step-by-step explanation:

In Finding The Factor Of A Number You Need To Find A multiplication of Two Numbers That Gives The Product 8.

So keeping this in mind you can make multiples of numbers which has an outcome of 8. So;

1×8=8 {So 1 is a factor of 8 and note that any number multiplied by 1 is the number itself}

2×4=8{Two multiplied by four is going to give you 8 that's why it's a factor of 8}

3×?=8{There is no number which can be multiplied by 3 which has it's outcome as 8 so 3 isn't a factor}

4×2=8{4 multiplied by 2 is the same as 2 multiplied by 4 so you can see that when you multiply two numbers and it has it's product as 8 those two numbers that you multiplied to get the 8 is a factor of 8}

5×?=8{With the number 5 you can see that there is no number which can be multiplied by 5 which has its outcome as 8 so 5 is not a factor of 8}

6×?=8{With the number 6 you will not get any number which can be multiplied by 6 to give you 8 so 6 isn't a factor of 8}

7×?=8{With the number 7 too you won't get any number to be multiplied by 7 which is going to give you 8 that's why it isn't a factor of 8}

8×1=8{With the number 8 you can clearly see that when 8 is multiplied by 1 the product is 8 so that makes it its factor}

After finding the multiplication of Two Numbers that are going to give you 8, you can conclude that you have found the factors of 8 and note that any number above 8 can't be a factor of 8.

So we can conclude that the Factors of 8 are;

store y has the better buy.

Answers

Answer: 10

Step-by-step explanation:

The value of k is 10.5.

What is meant by angle ?

An angle is a shape created by two rays or lines that meet at the same terminal.

Here,

∠XZY = (4k + 5)°

∠YXZ = (6k + 10)°

The exterior angle M = 115°

Therefore,

∠XYZ = 180 - 115

∠XYZ = 60°

So, we can write that,

∠XZY + ∠YXZ + ∠XYZ = 180°

(4k + 5)° + (6k + 10)° + 60° = 180°

10k + 75° = 180°

Therefore,

k = 105/10

k = 10.5

Hence,

The value of k is 10.5.
