Answer:

Fish and mammals are related, even though adult fish and adult mammals do not look alike.

Explanation:

Adult fish and adult mammals look very different. But the embryos of fish and mammals share a number of similarities. So, Mariam can conclude that fish and mammals are related, even though adult fish and adult mammals do not look alike.

I realized that the fish and mammals don't look alike but their embryos do so Fish and mammals are related, even though adult fish and adult mammals do not look alike.

Hope this helps if it does give it a thumbs up and a heart so I know it's right if it's wrong tell me what it was!!

WILL NAME THE BRAINLIEST! An airplane undergoes the following displacements: It first flies 72 km in a direction of 30° East of

nekit [7.7K]

Answer:

82.1 km

Explanation:

We need to resolve each displacement along two perpendicular directions: the east-west direction (let's label it with x) and the north-south direction (y). Resolving each vector:

$A_x = (72) sin 30^{\circ} =36.0 km\\A_y = (72) cos 30^{\circ} = 62.4 km$

Vector B is 48 km south, so:

$B_x = 0\\B_y = -48$

Finally, vector C:

$C_x = -(100) cos 30^{\circ} =-86.6 km\\C_y = (100) sin 30^{\circ} = 50.0 km$

Now we add the components along each direction:

$R_x = A_x + B_x + C_x = 36.0 + 0 +(-86.6)=-50.6 km\\R_y = A_y+B_y+C_y = 62.4+(-48)+50.0=64.6 km$

So, the resultant (which is the distance in a straight line between the starting point and the final point of the motion) is

$R=\sqrt{R_x^2+R_y^2}=\sqrt{(-50.6)^2+(64.6)^2}=82.1 km$

A skateboarder who travels 60 meters in 30 seconds has a speed of

natulia [17]

2m/s

Explanation:

Given parameters:

Distance traveled = 60m

time taken = 30seconds

Unknown:

Speed of skateboarder = ?

Solution:

Speed is the rate of change of distance with time taken. It is a scalar quantity that only revers magnitude;

Speed = $\frac{distance}{time}$

Speed = $\frac{60}{30}$ = 2m/s

Two brothers, Frank and Dion, are on roller skates and standing still when they push off from one another. Frank's mass is 103.4

tigry1 [53]

Around -3.5 ( might not be completely right ) Frank has a greater mass to he has a low velocity at first, Dion is around half of his weight so he doesn’t have to use as much force to get more than Frank
