Answer: 23x3y

step 1 ((2 • (x2)) • (y3)) • 22xy(-2)

step 2 (2x2 • y3) • 22xy(-2)

step 3 3.1 x2 multiplied by x1 = x(2 + 1) = x3

3.2 y3 multiplied by y(-2) = y(3 + (-2)) = y1 = y

Multiplying exponents:

3.3 21 multiplied by 22 = 2(1 + 2) = 23

A system of equations is shown below. Which of the following statements describes the graph of this system of equations in the (

Mamont248 [21]

Answer:

Option C. will be correct.

Step-by-step explanation:

The equations of straight lines are given as

3y - 5x = 15 ........... (1)

And, 6y - 10x = 30 ......... (2)

If we divide the equation (2), by 2 then we will get 3y - 5x = 15 which is nothing but the equation (1).

Therefore, those two equations (1) and (2) represents the same straight line.

Now, from equation (1), we can write $y = \frac{5}{3} x+ 5$ .

This is an equation of a straight line in slope-intercept form and here slope is positive.

Therefore, Option C. will be correct. (Answer)

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins th

Cloud [144]

Answer:

The mistake in Kevin's calculation is when calculating P(Red or Green).

Step-by-step explanation:

Given

$Sections = 10$

$Spins = 180$

$Red, Blue, Green, Yellow, Purple = 2\ each$

Required

Spot the mistake in Kevin's calculation

From the question, we have that:

Kevin's calculation

$P(Red\ or\ Green) = \frac{2}{10}$

Number of times;

$Times = \frac{2}{10} *180 = 36$

The mistake in Kevin's calculation is when calculating P(Red or Green).

$P(Red\ or\ Green) = \frac{Number\ of\ red\ or\ green}{Total}$

He considered only one section instead of both sections

The correction is:

Since, there are 2 green sections and 2 red sections.

The equation becomes

$P(Red\ or\ Green) = \frac{2 + 2}{10}$

$P(Red\ or\ Green) = \frac{4}{10}$

And the number of times is:

$Times = \frac{4}{10} * 180$

$Times = \frac{720}{10}$

$Times = 72$

Tyler bought 3 7/16 pounds of oranges write this amount using a decimal

morpeh [17]

Alright, lets get started.

Tyler bought pounds of oranges = $3\frac{7}{16}$

The order we have given is called mixed fraction.

Mixed fraction means a whole number combined with a fraction.

Means oranges = $3\frac{7}{16}=3 + \frac{7}{16}$

Means oranges = $3 + 0.4375$

Means oranges = 3.4375 pounds

So, the answer in decimal is 3.4375 pounds. : Answer

Hope it will help :)
