The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.

Answers

Answer 1

Answer:

147 cats

Step-by-step explanation

There are 3 dogs/ 7 cats

3x + 7x = 210

10x = 210

210 ÷ 10 = 21

Therefore,

x = 21.

dogs would be 3x (3 x 21) = 63

cats would be 7x (7 x 21) = 147

The regular price of a pair of Rothy's (water bottle shoes) is $145. They are on sale for 38% off. What is the sale price?

Answers

Answer:

$89.90

Step-by-step explanation:

38% corresponds to the decimal fraction 0.38.  

The amount of the discount is 0.38($145), or $55.10.  Subtracting this amount from the regular price yields $145 - $55.10 = $89.90.

A faster way of doing this problem is to subtract 0.38 from 1.00, obtaining 0.62, and then multiplying $145 by this 0.62:  $89.90.

Use a Pythagorean Triple to find x.

Answers

Answer:

x = 51

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )

x = [tex]\sqrt{2601}[/tex] = 51

Answer:

x = 51.

Step-by-step explanation:

The triple you require is 17-15-8

We have x-45-24

- that is three times each number in the triple.

So x = 3*17 = 51.

A line with a slope of -2 is written in the form y=mx+b.
what is the value of b If the line passes through the point (5,-7)?​

Answers

Answer:

b = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 2 , then

y = - 2x + b ← is the partial equation

To find b substitute (5, - 7 ) into the partial equation

- 7 = - 10 + b ⇒ b = - 7 + 10 = 3

Answers

Answer:The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness  of a line and the y-intercept is the point where the line intersects  the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)
