Answer:

128×5=640

640×5=3200

Multiply by 5

The pattern is a recurring sequence of digits, forms, colors, etc. It's also known as a sequence of numbers that relate to per in a specified way.

value = 128, 640, 3200

⇒ 128

Multiply by 5 into 128 so we get the value that is 640.

⇒ 128 × 5=640

After getting the value that is 640 again, multiplied by 5, we get the value that is 3,200.

⇒ 640 ×  5 = 3200

To find the pattern, we multiply the given value by 5, which is equal to 128, 640, and 3200.

Answer:

C

Step-by-step explanation: it's a negative slope, the y-intercept (b) is -1, and the rise over run is -4/1

The data in the scatterplot on monthly sales and advertising costs, show that:

In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.

In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

Answer:

Dennis's score = 104

Step-by-step explanation:

Let us represent:

Dennis's score = x

Amanda's score = y

Jorge's score = z

Three friends go bowling.​

Dennis's score is 46 points greater than​ Amanda's score.

x = 46 + y

​ Amanda's score is 70 points less than​ Jorge's score.

y = z - 70

If​ Jorge's score is​ 128

z = 128

what is​ Dennis' score?

Step 1

we solve for y = Amanda's score

y = z - 70

z = 128

y = 128 - 70

y = 58

Step 2

We solve for Dennis's score

x = 46 + y

x = 46 + 58

x = 104

Dennis's score = 104

Step-by-step explanation:

7:4 and 350:x

350/7 = 50

40 times 50 = 200

350:200

Plus, 350/50 = 7

        200/50 = 7

The solution is, 200 ducklings (350:200) ducklings are there​.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

here, we have,

given that,

The ratio of ducks to ducklings at a park is 7:4.

If there are 350 ducks,

let , x ducklings are there​

Answer:

The side opposite 30 is 9 ft.

The side opposite 60 is 15.59 ft.

Step-by-step explanation:

Below are pictures of how I got the answer.

I will provide steps to accompany each corresponding picture to further explain what I am doing.

1. This picture simply illustrates what the triangle looks like. The Hypotenuse is 18, as described in the problem.

2. I am showing how the sin will work. What is the opposite side and what is the hypotenuse. I picked this particular angle because it allow me to divide it by a number I already have, 18. I show that sin of 30 is 0.5

3. Now, we know what the side value is, 9. We can easily find the remaining side using Pythagorean theorem.

9^2 + y^2 =18^2

81 + y^2 = 324

y^2 = 243

y = 15.59

Answer: $467.21

Step-by-step explanation:

8% of 600 = 48

600 - 48 = 552

8% of 552 = 44.16

552 - 44.16 = 507.84

8% of 507.84 = 40.6272

8% of 507.84 ≈ 40.63

507.84 - 40.63 = 467.21

The amount that you save each month is half of the total tank value, $20.70.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Since, We know that a gallon of gasoline costs $2.56,

And, the tank holds 15 gallons.

Then to fill the tank, you need to pay:

= 15 × $2.76

= $41.40

Now, you have two friends, and each of the friends pays one-quarter of a full tank per month, then you only pay a fraction of the total, which would be one-half.

($41.40)/2 = $20.70

The amount that you save is:

S = $41.40 - $20.70

S = $20.70

So, the correct answer is, $20.70
