Find The Scale Factor For Of The Dilation Shown.A. 1/2B. 3/2C. 2D. 2/3NEED THIS BEFORE MIDNIGHT!! HELP

Answers

Answer 1
The answer is B (3/2).
Start by doing 6/4 to get 3/2.
It also works with 9/6 to get 3/2
Do what you want/What you started with.
Test it by multiplying 4 by 3/2 to get 6. It works!
Since it is a scale factor both sides grow by the same ratio. This is what we did above.

Nancy mistakenly measured the temperature of a heated liquid to be 48°C. The actual
temperature of the headed liquid was 50°C. What was the percent error?

Answers

Answer:

4.17% (nearest hundredth)

Step-by-step explanation:

What’s the length of this missing leg?

Answers

Answer:

b = 4.5 mm

Step-by-step explanation:

using Pythagoras theorem:

a² + b² = c²

4² + b² = 6²

b² = 6² - 4²

b² = 36 - 16

b² = 20

b = √20

b = 4.5

Pythagoras theorem:

a² + b² = c²

4² + b² = 6²

b² = 6² - 4²

b² = 36 - 16

b² = 20

b = [tex] \sqrt{20}[/tex]

b = 4.5

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.

x + y = 24

3x + 5y = 100

What does the solution of this system indicate about the questions on the test?

The test contains 4 three-point questions and 20 five-point questions.
The test contains 10 three-point questions and 14 five-point questions.
The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.

Answers

Answer:

10 three-point questions and 14 five-point questions.

Step-by-step explanation:

x+y = 24

3x+5y = 100

We can solve this system of equations using elimination. In order to do this, let's first multiply the first equation by 3...

3x+3y=72

3x+5y=100

Now, subtract the first equation from the second equation...

2y=28

Divide both sides by 2

y=14

Plug this back into any of the equations to solve for x...

x+14=24

x=10

There were 10 three-point questions and 14 five-point questions

Determine the slope and the y-intercept of the following equation.
2x + 7y = 8

Answers

Answer:

the slope = -2/7

the y-intercept = 8/7

Step-by-step explanation:

Rewrite the equation to a slope-intercept form:

7y = 8 - 2x

7y = -2x + 8

[tex]y=-\frac{2}{7}x+\frac{8}{7}[/tex]

so the slope = -2/7

the y-intercept = 8/7
