Answers

Answer: D

Step-by-step explanation: We first need to solve the inequality.

First subtract 10 from both sides to get -x < -8.

Now divide both sides by -1, but watch out.

If you multiply or divide both sides of an inequality by

a negative number, you must switch the direction of the inequality sign.

So we have x > 8.

Start with an open dot at 8 and draw and arrow to the right.

We use an option dot since x is greater than but not equal to 8.

So option D is your answer.

Answer:

The correct answer is D

When Dalvin runs the 400 meter dash, his finishing times are normally distributed with a mean of 65 seconds and a standard deviation of 1 second. Using the empirical rule, what percentage of races will his finishing time be between 64 and 66 seconds?

Answers

Answer:

68%.

Step-by-step explanation:

Dalvin's finishing time is normally distributed with a mean of 65 seconds and a standard deviation of 1 second.

Under the empirical rule, 68% of the results will be within 1 standard deviation.

Since the standard deviation is 1 second, 68% of Dalvin's finishing time will be between 64 and 66 seconds.

3x − x − 1 = 15
What is x

Answers

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8

Answer:

3x-x=15+1

2x=16

x=16/2

x=8

Which of the following equations are equations of a direct variation? Choose all that apply.
(a) x=−2y
(b) x+2y=12
(c) 3x−2y=0
(d) 5x^2+y=0
(e) y =0.3x +1.6
(f) y−2=x

Answers

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2 2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y 3x - 2y = 0

Answer:

(a) x = -2y

Step-by-step explanation:

You can tell if an equation is a direct variation equation if it can be written in the format y = kx.

Note that there is no addition and subtraction in this equation.

Let's put these equations in the form y = kx.

(a) x = -2y

y = x/-2 → y = -1/2x

This is equivalent to multiplying x by -1/2, so this is an example of direct variation.

(b) x + 2y = 12

2y = 12 - x

y = 6 - 1/2x

This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.

-2y = -3x

y = 3/2x

This follows the format of y = kx, so it is an example of direct variation.

(d) 5x² + y = 0

y = -5x²

This is not in the form of y = kx, so it is NOT an example of direct variation.

(e) y = 0.3x + 1.6

1.6 is being added to 0.3x, so it is NOT an example of direct variation.

(f) y - 2 = x

y = x + 2

2 is being added to x, so it is NOT an example of direct variation.

The following equations are examples of direct variation:

x = -2y

3x - 2y = 0

Kathy uses 8.6 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

Answers

Answer:Kathy uses 1.72 pint of white paint

Step-by-step explanation:

Total amount of paint ( Blue and white paint)= 8.6 pints

Amount of blue paint=4/5 x 8.6 = 6.88 Pints

amount of white paint = Total amount of paint - amount of blue paint

= 8.6 pints - 6.88 pints

=1.72 pint of white paint

express 4.67 as a mixed number

Answers

Answer:

4.671 = (4.67 × 100)(1 × 100) = 467100.

Step-by-step explanation:

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 467100 is also equal to 467100 when expressed as a mixed number.

Answer:

4 67/100

Step-by-step explanation:

From the info we have, we now that the whole number is 4.

.67 ends in the hundredths place which means it will be a decimal over 100.

Now you have 67/100 and since 67 is prime it can't be simplified.

Put them together and you get 4 67/100
