Nathaniel participated in an 18-mile race. He ran 1 2 mile in 1 6 hour. If he ran the entire race at the same pace, how long, in

Softa [21]

Answer:

24 hours

Step-by-step explanation:

set up a ratio:

12 miles = 16 hours

------------- ------------

18 miles = x hours

cross multiply

12m * x = 16h * 18 m

solve for x

x=16h * 18m / 12m = 24 hours

I need help with basic math. “Kara wrote a series of numerical expressions to generate a number pattern. 50-1 , 50-2, 50-3.... W

Let a, b and c be the first three terms of the sequence which are represent by the input of the table given in the attachment in the question and let p, q and r be the output of the table.

We need to check which table make the following equations TRUE.

$50-a=p\\ \\ 50-b=q\\ \\ 50-c=r$

Option A

$50-8=42\\ \\ 50-21=29\\ \\ 50-32=18\\ \\$

The output doesn't matches, so option A is not the right option.

Option B

$50-9=41\\ \\ 50-23=27\\ \\ 50-34=16$

The output doesn't matches, so option B is not the right option.

Option C

$50-11=39\\ \\ 50-24=26\\ \\ 50-35=15$

The output does matches, so option C is the correct option !

Which graph represents the circle given by the equation x + y - 4x + 9y -7 = 0?

PSYCHO15rus [73]

The graph of the circle equation is graph (d)

<h3>How to determine the circle?</h3>

The equation is given as:

x^2 + y^2 - 4x + 9y -7 = 0

Rewrite as:

x^2 - 4x + y^2 + 9y = 7

Express (x^2 - 4x) and (y^2 + 9y) as perfect squares.

So, we have:

(x - 2)^2 + (y + 3)^2 = 7 + 4 + 20.25

Evaluate the sum

(x - 2)^2 + (y + 3)^2 = 31.25

A circle equation is represented as:

(x - h)^2 + (y - k)^2 = r^2

Where

Center = (h, k)

Radius = r

So, we have:

(h, k) = (2, -3)

r^2 = 31.25

r = 5.5

The circle that has a center of (2, -3) and a radius of 5.5 is graph d

Hence, the graph of the circle equation is graph (d)

I NEED HELP ASAP MARK THEM WITH DOTS!!!

Given data:

$$1 \frac{4}{9} \text { and } 2 \frac{1}{3}$

Plot the points $1 \frac{4}{9} \text { and } 2 \frac{1}{3}$ on the number line.

Let us plot the first point $1\frac{4}{9}$ .

1 unit is completed. So count after 1 (indicated) in the number line.

point after 1 is $1\frac{1}{9}$

point after $1\frac{1}{9}$ is $1\frac{2}{9}$

point after $1\frac{2}{9}$ is $1\frac{3}{9}$

point after $1\frac{3}{9}$ is $1\frac{4}{9}$ .

So, move 4 points after 1 in the number line is $1\frac{4}{9}$ .

Now plot the point $2\frac{1}{3}$ .

To make the denominator 9, multiply and divide numerator and denominator by 3.

$$2 \frac{1}{3}=2 \frac{3}{9}$

2 unit is completed. So count after 2 (indicated) in the number line.

point after 2 is $2\frac{1}{9}$

point after $2\frac{1}{9}$ is $2\frac{2}{9}$

point after $2\frac{2}{9}$ is $2\frac{3}{9}=2\frac{1}{3}$

So, move 3 points after 2 in the number line is $2\frac{1}{9}$ .

The number line is attached below.
