Mike and Lilly are working together on a science project. They agreed to

meet halfway between their houses and ride their bikes to the library

together. Approximately how far will Mike and Lilly ride to the library once

they meet each other at the halfway point?

Answers

The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.

From the graph :

Mike's coordinate = (-4, 2) Lilly's coordinate = (2, - 2) Library coordinate = (4, 6)

Meeting point = Halfway point :

(x1 + x2) /2 ; (y1 + y2) / 2

X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1

Y - coordinate = (2 + (-2)) /2 = 0/2 = 0

Hence, meeting point = (-1, 0)

The distance between meeting point and library :

Distance = √[(x2 - x1)² + (y2 - y1)²]

Distance = √[(4 - (-1))² + (6 - 0)²]

Distance = √(25 + 36)

Distance = √61 = 7.8 miles

Therefore, the distance between halfway point and library ls approximately 7.8 miles

Z-49+851=100+21z /////////////////////////////////////////////////

Answers

Answer:

z=35.1

Step-by-step explanation:

Answer:

z = 351/10 or z = 35.1

Step-by-step explanation:

*Add/subtract numbers: -49 + 851 = 802

z + 802 = 100 + 21z

*Subtract 802 from both sides

z + 802 - 802 = 100 + 21z - 802

*Simplify

z = 21z - 702

*Subtract 21z from both sides

z - 21z = 21z - 702 - 21z

*Simplify

-20z = -702

*Divide both sides by -20

- 20z/20 = - 702/- 20

*Simlify

z = 351/10 or z = 35.1

A 4.0-kg cart moving due east at 9.0 m/s collides with a 3.0-kg cart moving due west. The carts stick together and come to rest after the collision. What was the initial speed of the 3.0-kg cart?

Answers

Since the carts stick together and come to rest after the collision, the initial speed of the 3.0-kg cart is 12 m/s.

Given the following data:

Mass of cart 1 = 4.0 kgVelocity of cart 1 = 9.0 m/sMass of cart 2 = 3.0 kg

To find the initial speed of the 3.0-kg cart, we would apply the law of conservation of momentum:

For a perfectly inelastic collision:

[tex]M_1V_1 - M_2V_2 = V_f(M_1 + M_2)[/tex]

When the carts stick together and come to rest after the collision, the final velocity is zero (0).

[tex]M_1V_1 - M_2V_2 = 0\\\\M_1V_1 = M_2V_2\\\\V_2 = \frac{M_1V_1}{M_2}[/tex]

Substituting the given parameters into the formula, we have;

[tex]V_2 = \frac{4(9)}{3}\\\\V_2 = \frac{36}{3}[/tex]

Initial speed = 12 m/s

Find the measure of the marked angles.
The measure of the angles is
___ degrees

Answers

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees

3 3/4 divided by 2 1/12 in simplest form

Answers

Answer: the final answer is 1 4/5 or 9/5

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

3 3/4 turns into 15/4 and 2 1/12 turns into 25/12

Second: then flip the 2nd fraction so it becomes 12/25

now multiply straight across: 15/4 x 12/25

15 x 12=180

4 x 25=100

180/100= 9/5= 1 1/4

How to divide two fractions?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

[tex]3\frac{3}{4}[/tex] can be written as [tex]\frac{15}{4}[/tex] and [tex]2\frac{1}{12}[/tex] can be written as [tex]\frac{25}{12}[/tex].

Keep 15/4 and change division sign to multiplication sign and reverse the fraction 25/12 as 12/25.

That is , [tex]\frac{15}{4} \div \frac{25}{12} = \frac{15}{4} \times \frac{12}{25}[/tex]

[tex]=\frac{3}{1} \times \frac{3}{5} =\frac{9}{5}[/tex]

So, quotient = 9/5

Therefore, simplest form of quotient of given fractions is 9/5.
