For this case we have the following multiplication:

5 * 216

We can rewrite this multiplication in the following way:

5 * (200 + 16)

From here, we apply the distributive property.

We have then:

(5 * 200) + (5 * 16)

Therefore, Jack's strategy is:

Write the number in an expanded form and then apply the distributive property.

The <em>correct answer</em> is:

He used the distributive property.

Explanation:

To rewrite a product using the distributive property, break one of the numbers up into two smaller, easier to multiply numbers. In this problem, Jack broke 216 into (200+16). He then multiplied by 5:

5(200+16)

Using the distributive property, we multiply the number outside by both factors inside:

5(200) + 5(16) = 1000+80 = 1080

This makes the number easier to multiply quickly.

Angle D has a measure between 0° and 360° and is coterminal with a –920° angle. What is the measure of angle D?
topjm [15]
Take -920/360 = -2.55555
Take the fraction part -0.5555555 * 360 = -200
The positive of that would be 160 degrees

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval. What
dezoksy [38]

Answer:

29.49% probability that a production time is between 9.7 and 12 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d, in which d is greater than c, is given by the following formula.

P(c \leq X \leq d) = \frac{d - c}{b-a}

Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval.

This means that a = 8, b = 15.8

What is the probability that a production time is between 9.7 and 12 minutes?

d = 12, c = 9.7.

So

P(c \leq X \leq d) = \frac{d - c}{b-a}

P(9.7 \leq X \leq 12) = \frac{12 - 9.7}{15.8 - 8} = 0.2949

29.49% probability that a production time is between 9.7 and 12 minutes

How can 1/5x − 2 = 1/3x + 8 be set up as a system of equations? a . 5y − 5x = −10. 3y − 3x = 24 b. 5y − 5x = −10. 3y + 3x = 24 c
VMariaS [17]
The answer is d. 5y − x = −10. 3y − x = 24

\frac{1}{5}x-2=  \frac{1}{3}x+8=y
⇒   y= \frac{1}{5}x-2
      y= \frac{1}{3}x+8
________________________
y= \frac{x}{5} -2= \frac{x}{5} - \frac{10}{5} = \frac{x-10}{5}
y= \frac{x}{3} +8= \frac{x}{3} + \frac{24}{3} = \frac{x+24}{3}
________________________
y= \frac{x-10}{5}            ⇒     5y=x-10
y= \frac{x+24}{3}           ⇒     3y=x+24
________________________
5y-x=-10
3y-x=24

which of the following correctly names a ray shown in the figure? my answer is D but i need it checked. Brainliest for correct a
Verdich [7]
The correct answer is actually 'B'. D does not name the ray because the way it is formatted, the line would go in the opposite direction it is facing currently and wouldn't be a ray. For D to be correct, it would have to be
