Answer:

3p(5p + 8t)

Step-by-step explanation:

15p^2 + 24pt

3(5p^2 + 8pt)

3p(5p + 8t)

The completely factored form of 15p^2 + 24pt is 3p(5p + 8t).

To factorize the expression 15p^2 + 24pt using superscripts, we can follow the same steps as before.

First, let's find the GCF of the coefficients 15 and 24, which is 3:

GCF(15, 24) = 3

Next, we'll look for the GCF of the variables p^2 and pt, which is p:

GCF(p^2, pt) = p

Now, we can factor out the GCF from each term:

15p^2 + 24pt = 3p(5p + 8t)

Therefore, the completely factored form of 15p^2 + 24pt is 3p(5p + 8t).

Step-by-step explanation:

Answer:

A) 10-14

B) 45

C) 6.7%

Step-by-step explanation:

A) The interval that contain the most values can be gotten by looking at the histogram and selecting the interval with the highest frequency. Hence the interval 10-14 contains the most values because it has a frequency of 20.

B)The total number of swimmers is gotten by summing all the frequency of each individual lap. Hence:

Total swimmers on team = 10 + 12 + 20 + 0 + 3 = 45 swimmers

C) The percentage of swimmers who swam more than 14 laps = (number of swimmers that swam more than 14 laps/total swimmers) * 100%

The percentage of swimmers who swam more than 14 laps = [(0 + 3)/45] * 100% = (3/45) * 100% = 6.7%

[tex]P(New\ House) = \frac{1}{6}[/tex]

Step-by-step explanation:

Given

See attachment

Required

[tex]P(New\ House)[/tex]

This is calculated as:

[tex]P(New\ House) = \frac{New\ House}{Total}[/tex]

From the attachment, we have:

[tex]New\ House = 60^o[/tex]

[tex]{Total}= 360^o[/tex] --- total angle in a pie chart

Note that the measurements must be converted to degrees (if not already in degrees).

So, we have:

[tex]P(New\ House) = \frac{60}{360}[/tex]

Simplify

[tex]P(New\ House) = \frac{1}{6}[/tex]

Answer:

THE ANSWER IS NOT C / 3

THE ANSWER IS "A"

Step-by-step explanation:

all the "hard" work is done (the numbers)...

lets start with the "units" at the end of the problem you have to have mm/day... so just start crossing out "top to bottom" when you see the same unit on the top and bottom... if you se day in the numerator and day in the denominator cross them out...

Do that and the one that has mm on the top and day on the bottom is the answer...

Step #2 ... two of the answers have that ... so now look for "silly fractions"

something like 1 year/ 999 days... your problem does not have totally silly things like that , but the WRONG answer has  1mm/ 10 cm (or something like that ) there is 10 mm in 1 cm, you choices has that opposit in one answer.

Answer:

x + y = 248

Step-by-step explanation:

Using the property : Sum of co- interior angles = 180

[tex]\angle y + 56 = 180\\\\\angle y = 180 - 56 = 124\\\\\angle x + 56 = 180\\\\\anle x = 180 - 56 = 124\\\\\angle x + \angle y = 124 + 124 = 248^\circ[/tex]

The value of 'x' and 'y' are 124° and 124°, respectively. Thus, the value of the expression x + y will be 248°.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides and angles are parallel and equal.

According to the definition, the value of 'x' and 'y' will be equal.

And the sum of adjacent angles will be 180 degrees. Then the equation is given as,

x + 56° = 180°

x = 124°

The sum of 'x' and 'y' is given as,

x + y = 124° + 124°

x + y = 248°
