Answer:

11. Triangles to rectangles: \frac{1}{4} or 1:4

    For each triangle there are 4 rectangles.

12. Soccer balls to footballs: \frac{3}{5} or 3:4

    For every 3 soccer balls there are 5 Footballs.

13. - Kittens to puppies: \frac{3}{1} or 3:1

       For every 3 kittens there is a puppy.

    - Puppies to kittens: \frac{1}{3} or 1:3

      For each puppy there are 3 kittens.

Step-by-step explanation:

To express a counting problem as a ratio you should divide the number of things before the word "to" by the number of things after the word "to". A ratio can be expressed as a fraction or separating the two numbers with a colon (a:b).

Let's apply this to each one of our problems.

11. Here we have triangles to rectangles, so we are going to divide the number of triangles by the number of rectangles.

We can count 2 triangles and 8 rectangles from our picture, so

Triangles to rectangles = \frac{NumberofTriangles}{NumberifRectangles} =\frac{2}{8}

Notice that both numerator and denominator of our ratio are divisible by 2, so simplify it, we just need to divide them both by 2:

\frac{2}{8} =\frac{\frac{2}{2} }{\frac{8}{2} } =\frac{1}{4}

So the ratio from triangles to rectangles is \frac{1}{4} or 1:4

which means that for 1 triangle there are four rectangles.

12. Here we have soccer balls to footballs, so we are going to divide the number of soccer balls to the number of footballs and simplify our resulting fraction. We have 6 soccer balls and 10 footballs in our picture

Soccer balls to footballs = \frac{NumberofSoccerBalls}{NumberofFootballs} =\frac{6}{10} =\frac{\frac{6}{2} }{\frac{10}{2} } =\frac{3}{5}

For every 3 soccer balls there are 5 Footballs.

13. Here we have kittens to puppies or puppies to kittens. We know that there are 36 Kittens and 12 puppies.

- Kittens to puppies = \frac{NumberofKittens}{NumberofPuppies} =\frac{36}{12} =\frac{\frac{36}{12} }{\frac{12}{12} } =\frac{3}{1}

For every 3 kittens there is a puppy.

- Puppies to kittens = \frac{Number of Puppies}{NumberofKittens} =\frac{12}{36} =\frac{\frac{12}{12} }{\frac{36}{12} } =\frac{1}{3}

For each puppy there are 3 kittens.

Write the equation of the line that passes through the points (-3, -3) and (8,7).
Verizon [17]

Answer:

y + 3 = 10/11(x + 3)

Step-by-step explanation:

Given the points (-3, -3) and (8, 7), we can use these coordinates to solve for the slope of the line using the formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (-3, -3)

(x2, y2) = (8, 7)

Substitute these values into the slope formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{7 - (-3)}{8 - (-3)} = \frac{10}{11}

Thus, slope (m) = 10/11.

Next, using the slope (m) = 10/11, and one of the given points (-3, -3), we'll substitute these values into the point-slope form:

y - y1 = m(x - x1)

Let (x1, y1) = (-3, -3)

m = 10/11

y - y1 = m(x - x1)

y - (-3) = 10/11[x - (-3)]

Simplify:

y + 3 = 10/11(x + 3) this is the point-slope form.

Determine The mean,median,mode, and range for each data set A. {2,2,7,9,10}​
Zarrin [17]

Answer:

Mean: 6, Median: 7, Mode: 2, Range: 8

Step-by-step explanation:

<h3>Mean:</h3>

The mean is the average of the data set.

Add all the terms together:

2+2+7+9+10=\\4+7+9+10=\\11+9+10=\\20+10=\\\boxed{30}

Divide the sums by the number of terms:

There are 5 terms in the data set.

30/5=6

<u>The mean is 6.</u>

<h3>Median:</h3>

The median is the middle value of the data set.

The data set given already has the numbers in ascending order.

Seven appears to be in the middle of the set.

{2,2,<u>7</u>,9,10}​

<u>The median is 7.</u>

<h3>Mode:</h3>

The mode is the number that appears the most in a data set.

The number two appears twice in the data set, and all other numbers (7, 9, and 10) appear once.

<u>The mode is 2. </u>

<h3>Range:</h3>

The range is the difference between the largest data value in the set and the smallest data value in the set.

In the given set, 10 is the biggest and 2 is the smallest.

10 - 2 = 8

<u>The range is 8. </u>

B^2-4b-12=0 please help me
Olegator [25]

Answer:

Step-by-step explanation:

 b² - 4b - 12 = b² - 6b + 2b - 2*6

=b*(b -6) + 2*(b - 6)

= (b - 6) (b + 2)

 b² - 4b - 12 = 0

(b - 6) (b + 2) = 0

b - 6 = 0     or b + 2 = 0

b = 6           or b =  -2
