1. A rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit

kykrilka [37]

Answer: The rabbit is hopping at 3 feet/ sec in speed

Step-by-step explanation:

Step 1

Let the The number of feet of the rabbit be expressed as N

AND time rabbit spends hopping can be expressed as t

From the question, The number of feet varies directly with the time rabbit spends hopping can be expressed as

N α t

Let us introduce a constant of proportionality ,S which represents speed in this case, we now have that

N = St

STEP 2 -- SOLVING

If the rabbit hop 6 feet in 2 seconds, Then speed =

N = St

6= S X2

S = 6/ 2

S = 3

also

If the rabbit hop 12 feet in 4 seconds, Then speed =

N = St

12= S X 4

S = 12/ 4

S = 3

Also recall

that Speed = Distance / time

Pluging the values in the first case,

speed = 6 feet/ 2 secconds = 3 feet/ seconds

in the second case

Speed= 12 feet/ 4 second s= 3 feet/ secs.

Pleases help with 4-9!

Serhud [2]

Step-by-step explanation:

The answer is

4_

$m = \frac{4 - 0}{0 - ( - 2)} = \frac{4}{2} = 2$

9_

$m = \frac{3 - 0}{0 - 4} = \frac{ - 3}{4}$

3(x-5)<=30how do you solve this problem

earnstyle [38]

The way that it is written is odd.

If the problem was 3(x-5)=30, it would be 3x-15=30.

Add 15 to both sides.

3x=45

Divide both sides by 3.

x=15

If it's supposed to be 3(x-5)<30, your answer would be the same, except:

x<15.

I'm not sure why it has both signs, especially next to each other.

I hope this helps :)

Triangle DEF is similar to triangle D'E'F'.Triangle D E F is rotated about point F and is shrunk to form triangle D prime E prim

Leviafan [203]

Answer:

The answer is "Rotation and dilation".

Step-by-step explanation:

The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

The vertex angle of an isosceles triangle is 20° less than the sum of the base angles. Which system of equations can be used to

WINSTONCH [101]

The answer to the above question can be explained as under -

We know that, the sum of angles of triangle is 180°.

So, vertex angle plus base angles are equal are equal to 180°.

Let the vertex angle be represented by "v" and base angles be represented by "b".

Thus, v + b + b = 180°

So, v + 2b = 180°

Next, the question says, the vertex angle is 20° less than the sum of base angles.

Thus, 2b - 20° = v

<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
