According to business insider, you can make an average of $0.01 to $0.02 for each sponsored view on TikTok. So if you have a video with 100,000 views, you can make 1000 dollars in sponsorships. After you have built a following on the app, you can reach out to brands and offer your services.He said that a creator with one million followers and good engagement should charge between $5,000 and $10,000 for a sponsorship on TikTok. That number is constantly shifting, however, as the platform matures.

Answer:

As

RS is corresponding to TX

Hence, we conclude that:

Step-by-step explanation:

Given

△RST ≅ △TXY

To determine:

RS = ?

As

△RST ≅ △TXY

So the triangles △RST and △TXY are congruent to each other.

We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that:

We need to determine RS

as

RS is corresponding to TX

i.e. RS  = TX

Hence, we conclude that:

you cannot divide by 0

so solve

y(z+5)=0

y=0 and z+5=0

y=0 and z=-5

excluded values are y=0 and z=-5

Have a great day

Answer:

If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). A solution to a system of equations means the point must work in both equations in the system.

Answer:

2/3

Step-by-step explanation:

Since you need to find the mising number, I will give it the variable (v)

So the equation is now:

1½v is the same as 1½ x v

3½ + (1½v) = 4½

I need to undo addition so I subtract.  To undo you need to look at the sign at the front of the number, since there was no negative sign I can infer that 3½ is positive.  I need 3½ to cancel out and become 0, so I subtracted 3½ with 3½.  What you do to one side of the equal sign, do to the other.  4½ subtract 3½ is 1.

The equation is now:

1½v = 1

I need to undo multiplication, so I divide 1½ by 1½.  It cancels out, and I what you do to one side of the equal sign, you do to the other. 1 divides by 1½ is 2/3.  (I used a calculator for this part)

Step-by-step explanation:

w = 3(2a + b) - 4

Answer:

[tex]x+y\geq 1[/tex]

[tex]x\geq 2y[/tex]

[tex]x\geq \frac{1}{4}[/tex]

Step-by-step explanation:

In order to solve this problem, we just need to translate mathematically what the problem is talking about. First, we know that:

x=# of hours she spent running on her wheel.

y = # of hourse she spent scratching at her cage.

So, let's split the problem into little chunks of information that will be easier to translate. This is split it into sentences.

So first:

Julie's pet hamster Zoe kept Julie awake for at least an hour running on her exercise wheel and scratching at the corner of her cage. This means that the least amount of time Julie was awake as an hour in total, so this can be written as an inequality like this:

time spent running + time spent scratching is less than or equal to 1 hour

[tex]x+y\geq 1[/tex]

next,

Zoe ran on the wheel at least twice as long as she scratched at the quarters of her cage.

This is:

[tex]x\geq 2y[/tex]

and finally, she spent more than 1/4 of an hour running on her wheel.

[tex]x\geq \frac{1}{4}[/tex]

so the system of inequalities is the following:

[tex]x+y\geq 1[/tex]

[tex]x\geq 2y[/tex]

[tex]x\geq \frac{1}{4}[/tex]

Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To make green paint, Andre uses a ratio of 5 cups yellow paint to 2 cups blue paint.

To make the same shade of green using 8 cups of blue paint, we need to use the same ratio of yellow paint to blue paint as before.

So we can set up a proportion:

5/2 = x/8

where x is the amount of yellow paint Andre needs.

Solving for x, we get:

x = (5/2) x 8 = 20 cups

Andre needs 20 cups of yellow paint to make the same shade of green using 8 cups of blue paint.

To make the same shade of green using 15 cups of yellow paint, we can set up another proportion:

5/2 = 15/y

where y is the amount of blue paint Andre needs.

Solving for y, we get:

y = (2/5) x 15 = 6 cups

Therefore,

Andre needs 6 cups of blue paint to make the same shade of green using 15 cups of yellow paint.
