**Answer:**

The horizontal component of the velocity of the helicopter is approximately 77.82 m/s

**Explanation:**

The given parameters are;

The speed of the helicopter, v = 95 m/s

The angle in which the helicopter is flying = 35° to the ground

The horizontal component of the velocity is given by the component of the magnitude, R, of the velocity of the helicopter in the x-direction as follows;

[tex]v = \sqrt{v_x^2 + v_y^2}[/tex]

Where;

vₓ = v × cos(θ) = The horizontal component

[tex]v_y = v \times sin(\theta)[/tex] = The vertical component

∴ The horizontal component of the velocity, vₓ, of the helicopter with 95 m/s velocity moving at an angle of 35° to the horizontal is given as follos

vₓ = 95 × cos(35°) ≈ 77.82 m/s

The horizontal component of the velocity of the helicopter ≈ 77.82 m/s.

Yodelin has fifty quarters and dimes. Their total value is $9.80. Which of these systems of equations can be used to find the number of quarters (q) and

dimes (d) Yodelin has?

**Answer:**

**q + d = 50
**

**
25q + 10d = 980
**

**Explanation:**

The equation that can be employed to determine the number of quarters(q), as well as, dimes(d) that Yodelin has would be:

q + d = 50...(1)

25q + 10d = 980...(2)

Multiplying (1) by 25

25q + 25d = 1250 ...(3)

25q + 10d = 980...(4)

subtracting (4) from (3)

15d = 270

d = 18

q = 50 - 18

= 32

The **system** of the **equations** could be

**q + d = 50**

**25q + 10d = 980**

Since Yodelin has **fifty quarters** and **dimes**. Their total value is $9.80.

So here the equations be

q + d = 50...(1)

25q + 10d = 980...(2)

Now we have to **Multiplying** (1) by 25

So,

25q + 25d = 1250 ...(3)

25q + 10d = 980...(4)

Now

subtracting (4) from (3)

15d = 270

d = 18

So,

q = 50 - 18

= 32

Three toy boats with the same mass were in a lake. Two boats were moving and one was stopped. Each boat got bumped by another boat, but not in the same direction. All the boats changed speed as a result of being bumped. Use the information in the diagram to answer. Which toy boat exprienced the strongest force when it was bumped ? How do you know ?

The answer is " The orange and gray toy boats experienced the strongest force because both gained the same force as they sped up the blue boat lost force so it slow down

**Explanation:**

Trust me I did this one for an assignment

The **boat** that will experience the** strongest force** is the boat that has the** highest speed**.

According to **Newton's second law** of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

[tex]F = \frac{mv}{t}[/tex]

where;

The **force** **experienced** by the **boats **is directly proportional to the **velocity** of their motion. Since the **boats** have the same **mass**, the force experienced by each boat will depend on the **speed** with which the boat moves.

Thus, the **boat** that will experience the** strongest force** is the boat that has the** highest speed**.

how much force is needed to accelerate 300 kg at a rate of 4 m/s/s

**Answer:**

1200

**Explanation:**

Force = Mass x Acceleration

**Answer:**

[tex]\boxed {\tt 1,200 \ Newtons }[/tex]

**Explanation:**

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass is 300 kilograms.

The acceleration is 4 meters per second squared.

[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 300 \ kg * 4 \ m/s^2[/tex]

Multiply.

[tex]F= 1200 \ kg * m/s^2[/tex]

1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.

[tex]F= 1200 \ N[/tex]

The force needed is **1,200 Newtons.**

**Answer:**

Sections 3 and 4

**Explanation:**

The correct answer would be **sections 3 and 4**.

*The velocity of an object is the speed of the object in a particular direction. In this case, the speed of the racer is constant irrespective of the distance or the direction. Hence, the sections of the race during which the racer's velocity would be the same would be the sections in which the racer faces the same direction - which is sections 3 and 4.*

Lucy and JoJo need to make 140 cupcakes for the school dance. Lucy made 35 of the cupcakes. JoJo made 42 cupcakes What fraction of the cupcakes do Lucy and JoJo still need to make?

Answer:

9/20

Explanation:

According to this question, Lucy and JoJo need to make 140 cupcakes for the school dance. Lucy made 35 of the cupcakes while JoJo made 42 cupcakes. This means that in total, (42 + 35) cupcakes has been made by both Lucy and JoJo

That is, 77 cupcakes out of 140 has been made. This is 77/140 i.e. 11/20

Since 77/140 cupcakes has been made, Lucy and JoJo still need to make;

140 - 77 = 63 cupcakes to meet up their target for the school dance.

This means that the fraction left is 63/140

63/140 in its lowest term is 9/20

Hence, 9/20 of the cupcakes still need to be made by Lucy and JoJo.
