Answer:

It would be C , 7 root 2

Step-by-step explanation:

you would have to find the Sin of 45. So you set up a proportion ( you can do this on a calculator)

sin 45=7/x and then calculate that and solve.

If you dont have a calc then the sin of 45 is 1/root2

Penny is going to fly her plane to her sister's house, which is 544.32 miles away. Penny's airplane flies at an average speed of

Sedbober [7]

Answer:

0.81 hour

Step-by-step explanation:

Given data

Distance= 544.32 miles

Speed= 672 miles per hour.

We know that

Speed= distance/time

Substitute

672= 544.32/time

cross multiply

time*672= 544.32

time= 544.32/672

time= 0.81 hour

25 POINTS!!! The equation y=470x represents the relationship between x, the time that a plane flies in hours, and y, the distanc

sineoko [7]

Answer:

Step-by-step explanation:

For plane A,

Equation that represents the relationship between time 'x' and distance 'y' is,

y = 470x

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = slope = 470

b = 0

Here, slope represents the speed of plane A.

Therefore, speed of plane A = 470 mi per hour

For plane B,

From the given table,

Slope of the graph = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{960-480}{2-1}$

= 480

Speed of plane B = 480 miles per hour

Since, speed of plane B is more than plane A,

Plane B is flying faster.
