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.

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

**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.

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.

Answer:

Kindly check the explanation section.

Explanation:

The statement given in the question or problem above is true or let's say it is correct. And the statement describes different kinds or types of push up.

Push up is a kind of excercise that is being done mainly to strengthen the arm and the cheat. The way one goes about it determines which part of the body one is strengthening.

The kind of push up in which one has to close up the gap between his or hands is known as the close push ups. This kind of push up strengthens the arm more than the other part of the body and the more one puts his or her hands closer the more problematic the push up excercise becomes.

Other types or kinds of push ups are the Slow Eccentric Push Ups, Wide Push Ups, Staggered Push Ups, T push ups, Fingertip Push Ups and many more.

**Newton's First Law of Motion **:

An object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

Here this statement is best represented by the statement : *Unbalanced forces cause an object to move.** ***[**** ****option**** ****c**** ****]**

**More**** to**** know**** ****:****-**

Newton's 3 laws of motion :-

**Newton's**** ****First**** Law**** of**** Motion**** ****:****-**

It states that an object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

**Ex**** ****-**** ** (i) We tend to fall backwards while standing in the bus , when it starts suddenly.

(ii) We tend to fall forward while standing in the bus , when it stops suddenly.

**Newton's ****Seco****nd**** Law of Motion :-**

It states that the rate of change of momentum is directly proportional to the applied force in the direction of the force . That is ∆p [tex]\propto[/tex] Force .

**Ex**** ****-**** **(i) When we push car & a truck with same force the car will have Greater acceleration due to less mass . (Imaginary case ).

(ii) We feel easy to push a empty cart than a full cart .

**Newton's ****Third**** Law of Motion :-**

It states that every action has equal and opposite reaction .

**Ex**** ****-**** **(i) We are able to walk on ground due to Newton's third law of motion .

(ii) When we push wall it also applies equal and opposite force .

"**Unbalanced **forces cause an **object **to move " is the sentence that describes **Newton's first law.**

A **body **remains in the state of **rest **or uniform **motion **in a **straight **line unless and until an **external **force acts on it.

The **object **is to be rest if the **velocity **and **acceleration **are zero. When an object is in **motion**, **velocity **is **not **equal to **zero **(v ≠ 0) but **acceleration **(a = 0) is equal to **zero**. Therefore, the **object **will continue in motion with **constant **velocity in the **same **direction.

Example:

If we **jump **from a bus while **moving**, our body will be like still moving in the same **direction **of the vehicle. When your feet hit the ground, the **grounds **act on your feet and stop moving. You will fall because the upper part of your body didn't stop and you will **fall **in the **direction **you were moving.

If the **object **have the greater **mass**, then the object will have more **inertia**. Forces can change the **object's **motion.
