Answer:

No, it is not correct.

Step-by-step explanation:

Here, the given problem,

17 × 24

∵ 17 = 10 + 7

And, 24 = 20 + 4

Thus, 17 × 24 = (10 + 7)(20 + 4)

= 10 × 20 + 10 × 4 + 7 × 20 + 7 × 4

= 200 + 40 + 140 + 28

= 408

By comparing the above steps and Sebastian's model,

It is clear that he did incorrectly multiply 7 by 20,

i.e. he must write 140 instead of 40 while adding.

Sebastian's model is not correct because 20x7 does not equal 14.

The endpoints of are A(2, 2) and B(3, 8). is dilated by a scale factor of 3.5 with the origin as the center of dilation to give
goldfiish [28.3K]

Answer:

The given line segment whose end points are A(2,2) and B(3,8).

Distance AB is given by distance formula , which is

if we have to find distance between two points (a,b) and (p,q) is

=  \sqrt{(p-a)^2+(q-b)^2}

AB= \sqrt{(3-2)^2+(8-2)^2}=\sqrt{1+36}=\sqrt{37} = 6.08 (approx)

Line segment AB is dilated by a factor of 3.5 to get New line segment CD.

Coordinate of C = (3.5 ×2, 3.5×2)= (7,7)

Coordinate of D = (3.5×3, 3.5×8)=(10.5,28)

CD = AB × 3.5

CD = √37× 3.5

     = 6.08 × 3.5

= 21.28 unit(approx)

2. Slope of line joining two points (p,q) and (a,b) is given by

m=\frac{q-b}{p-a}

m= \frac{8-2}{3-2}=6

As the two lines are coincident , so their slopes are equal.

Slope of line AB=Slope of line CD = 6

Please help me out! I keep getting the wrong answer
Tamiku [17]

The total amount of people who ordered a large is 5 + 12 + 8 = 25 people.

The amount of customers who bought a large cold drink is 5.

The probability that someone bought a large cold drink is 5 out of 25 people.

This is 5/25 which is 1/5 which is .2

Convert the decimal to a fraction by multiplying by 100 and adding a percent sign at the end.

.2 x 100 = 20%

Edit:

The probability was supposed to be if the customer ordered a cold drink based on people who ordered large.

The amount of people who ordered a large drink is 22 + 5 = 27.

The amount of people who ordered a cold large is 5.

To find the percent, divide the people who ordered cold large by the total people who ordered large.

This would be 5/27 which in decimal form is .185185

To convert to a percent, multiply by 100 and add a percent sign after it.

.185185 x 100 = 18.5185%

The question says to round to the nearest percent so your answer is:

19%

Find the slope of each line
Kaylis [27]

Answer:

10

Step-by-step explanation:

You have to go up 10 places to get from the first point to the second

You also have to go 1 place to the right

Since the slope is Y/X, the slope of this line is 10/1
