Answer:

D. John's boat was farther and faster

Step-by-step explanation:

The equation tells you that at x = 0, Roberta's boat was 10 miles from the dock. The words tell you John's boat started 20 miles from the dock, so his boat started farther away.

John's boat traveled a distance of (55 -20) = 35 miles in 5 hours, so the speed was (35 mi)/(5 h) = 7 mi/h. The equation tells you Roberta's boat traveled 6 miles for each hour, so John's boat was faster.

John's boat was farther and traveled more quickly

<em>Additional comment</em>

The variables in Roberta's equation are not defined. In order for the problem to make sense, we must assume that x represents time in hours, and y represents distance in miles.

-2/3 is the simplified form of the expression -1/2 ÷ 3/4.

<h3>What is the simplified form of the given expression?</h3>

Given the expression in the question;

-1/2 ÷ 3/4

To divide by a fraction, multiply by its reciprocal.

-1/2 ÷ 3/4

Reciprocal of 3/4 is 4/3

Hence

-1/2 × 4/3

Next, we cancel out the common factor of 2

Factor out 2 from 4

-1/2 × 2(2)/3

-1/1 × 2/3

( -1 × 2 ) / ( 1 × 3 )

(-2) / (3)

-2/3

Therefore, the simplified form is -2/3

The following graph represents the distance a commercial airplane travels over time, at cruising speed and an altitude of 35,000

ANEK [815]

Answer:

see the explanation

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in hours

y ----> the distance in miles

<em>Find the value of k</em>

For the point (4,2268)

$k=\frac{2,268}{4}=567\ mph$

The slope represent the speed of the airplane

The linear equation is

$y=567x$

Part 1 :

The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.

Part 2 :

The point (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours

I need help with these please... anyone?

Svetlanka [38]

The total measure of the interior angles of each figure will be:

180 (n-2) = 180 (4 - 2) = 360

Now add all those angles and set them equal to 360.

41 + 133 + 86 + x = 360

x is the unknown angle.

260 + x = 360
x = 100

The missing angle that is Not labeled in any of the figure is 100°

Hope this helps :)

Which represents a unit rate? The cost of cat food is $36 per 3 bags

coldgirl [10]

Step-by-step explanation:

To find unit rate

1 bag = 36÷ 3 = 12

So unit rate = $12
