A caterpillar crawling in a straight line across a coordinate plane starts at point (-3, -4) and ends at point (25, 38). Counting the start point and end point, how many points with integer coordinates does the caterpillar touch?

Answers

Answer 1

Answer:

15 points

Step-by-step explanation:

The start and end point of the caterpillar path are;

Start point = (-3, -4)

End point = (25, 38)

The slope of the caterpillar's path, 'm', given the 'x', and y-coordinates of two points is given by the following formula;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, m = (38 - (-4))/(25 - (-3)) = 1.5

The equation of the caterpillar's path in point and slope form is given as follows;

y - (-4) = 1.5 × (x - (-3))

y + 4 = 1.5 × (x + 3)

y + 4 = 1.5·x + 4.5

y = 1.5·x + 4.5 - 4 = 1.5·x + 0.5

y = 1.5·x + 0.5

Given that the 0.5 is added to the product of 'x' and 1.5, the points that have both integer points for 'x', and 'y' are the points that have odd number values of 'x', as follows;

(-3, -4), (-1, -1), (1, 2), (3, 5), (5, 8), (7, 11), (9, 14), (11, 17), (13, 20), (15, 23), (17, 26), (19, 29), (21, 32), (23, 35), (25, 38)

Therefore, we have 15 points counting the start and end points with integer coordinates

.) Which ordered pair shows an equivalent ratio
of pounds to dollars?
(24,30)
(20,25)
(25, 20)
(40.36)


Answers

Answer:

I think (25, 20) is your answer. hope it helps.

The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The coordinates from graph are (5, 4), (10, 8), (15, 12) and (20, 16).

Equivalent ratios are ratios that can be simplified to the same value by dividing both the values by a common fraction.

Here,

(5, 4)=5(5, 4)=(25, 20)

(10, 8)=2(10, 8)=(20, 16)

(15, 12)=2(15, 12)=(30, 24)

(20, 16)

The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

I think the question is asking for the ratio to be simplified, if so then that's what the answer is.

Answer:

75

Step-by-step explanation:

12 : 50 :: 18 : x

In proportion, Product of extremes  = Product of means

                       12 * x = 50*18

                             [tex]x =\frac{50*18}{12}=\frac{50*3}{2}[/tex]

Caroline and Chase are working on math homework. They decide to race to see who can finish first. Caroline is on number 12 and can solve 1 math problem in 1.5 minutes. Chase is on number 16 and can solve 1 math problem in 2 minutes. How many minutes will it take before they are on the same problem?​

Answers

Answer:

It will take 24 minutes before they are on the same problem.

Step-by-step explanation:

Caroline is on number 12 and can solve 1 math problem in 1.5 minutes.

Per minute, she solved [tex]\frac{1}{1.5} = \frac{2}{3}[/tex] of a problem. So, after t minutes, she will be on the problem:

[tex]Ca(t) = 12 + \frac{2t}{3}[/tex]

Chase is on number 16 and can solve 1 math problem in 2 minutes.

Per minute, he solved [tex]\frac{1}{2}[/tex] of a problem. So, after t minutes, he will be on the problem:

[tex]Ch(t) = 16 + \frac{t}{2}[/tex]

How many minutes will it take before they are on the same problem?​

This is t for which:

[tex]Ca(t) = Ch(t)[/tex]

So

[tex]12 + \frac{2t}{3} = 16 + \frac{t}{2}[/tex]

[tex]\frac{2t}{3} - \frac{t}{2} = 4[/tex]

[tex]\frac{4t-3t}{6} = 4[/tex]

[tex]\frac{t}{6} = 4[/tex]

[tex]t = 24[/tex]

It will take 24 minutes before they are on the same problem.

12 of the students in the art class like to draw animals these 12 students make up 24% of the art class how many students are in the art class

Answers

Answer:

50 students in total or X=50

Step-by-step explanation: 12 is 24% of X

We can make this into a box-like figure

12  24

X   100          X is the missing number

We then multiply 12 by 100 which equals to 1,200.

We then divided the 1,200 by 24, this results in your X which equals to 50.

X=50 students

HELP ME Write and solve a proportion to find y.

Answers

Given:

A figure of dilation and the center of dilation is O.

To find:

The value of y.

Solution:

The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).

[tex]d'\propto d[/tex]

[tex]d'=kd[/tex]

[tex]\dfrac{d'}{d}=k[/tex]

Where, k is the scale factor or constant of proportionality.

So, the scale factor for the given dilation is

[tex]k=\dfrac{OB'}{OB}[/tex]

[tex]k=\dfrac{36}{16}[/tex]

[tex]k=\dfrac{9}{4}[/tex]

We know that,

[tex]k=\dfrac{\text{Side length of image}}{\text{Corresponding side length of original figure}}[/tex]

[tex]\dfrac{9}{4}=\dfrac{A'C'}{AC}[/tex]

[tex]\dfrac{9}{4}=\dfrac{27}{y}[/tex]

[tex]9\times y=27\times 4[/tex]

Divide both sides by 9.

[tex]y=\dfrac{27\times 4}{9}[/tex]

[tex]y=3\times 4[/tex]

[tex]y=12[/tex]

Therefore, the value of y is 12.
