Answers

Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15

Dr. Wong has a table of data in her veterinary office that shows the average lifespans and weights of several popular dog breeds. Alfonso made a scatterplot of these data for a math project.

Answer the questions to make predictions about the lifespan of a specific breed of dog.

1. Describe the association shown by this scatterplot.

2. Alfonso is thinking of getting a bloodhound. Bloodhounds usually weigh about 90 pounds. Based on the data, estimate for the lifespan of a bloodhound. Explain how you made your estimate.

3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:

1. Alfonso didn't use a good estimation method,
2. Dani doesn't remember Ol' Sniffy's age correctly, or,
3. Ol' Sniffy lived an unusually long time?

Justify your answer.

Answers

Answer:

1. The heavier the dogs are, the shorter lifespan they have.

2. The lifespan of a bloodhound is on average 10 years long

3. Number 2

Step-by-step explanation:

#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.

#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.

#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)

what is 5.5x + 1−(1.5x+17)?

Answers

Answer:

4x - 16

Step-by-step explanation:

5.5x + 1 - (1.5x + 17)

5.5x + 1 -1.5x -17

Combine like terms

4x + 1 -17

4x -16

The Simplified Expression is 4x - 17.

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

5.5x + 1−(1.5x+17)

Now, simplifying the expression

5.5x + 1 - 1.5x - 17

Now, combining the like terms

= (5.5 x - 1.5x ) + 1 - 17

= 4x - 17

What is the approximate area of the figure below?

A. 27 square units
B. 29 square units
C. 30 square units
D. 36 square units

Answers

The approximate area of the actual figure is 29 square units

How to approximate the area?

From the complete question, the figure has the following shapes and dimensions:

Rectangle: 4 units by 5 unitsTriangle: Base = 3 units; Height = 6 units

The area of the figure is then calculated using:

Figure = Area of rectangle + Area of triangle

So, we have:

Figure = 4 * 5 + 0.5 * 3 * 6

Evaluate

Figure = 29

Hence, the approximate area of the figure is 29 square units

Answers

Answer:

Answers

First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.
