The number of bears, b is 300 for the company has to sell in one day to equal its daily cost.

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

A toy company spends $1800 per day for factory expenses plus $9 to make each teddy bear.

And, They sell the teddy bears for $15 a piece.

Let number of bears for the company has to sell in one day to equal its daily cost = b

Hence, We can formulate the inequality as;

⇒ 15b = 9b + 1800

Solve for b;

⇒ 15b - 9b = 1800

⇒ 6b = 1800

⇒ b = 300

Thus, There are 300 teddy bears has to sell in one day.

An inequality to determine at what times the car will be ahead of the truck is; 63x > 55x + 30

The graph of the inequality is attached and the solution is (3.75, 236.25).

We are told that;

x represent the number of hours that the car and truck travel

The truck is traveling at an average rate of 55 mph. Thus, the expression 55x represents the distance the truck travels in x hours.

The car is traveling at a rate of 63 mph. Thus, the expression 63x represents the distance the car travels in x hours.

In the beginning, the truck was 30 miles ahead of the car. So, we need to solve the inequality:

63x > 55x + 30

Use technology to graph y = 63x and y = 55x + 30 gives us;

Answer: D - 14

Step-by-step explanation:

1 gallon = 2.15

So to find how many gallons is worth 30.10, divide by 2.15

30.10 ÷ 2.15 = 14

Answer:

Step-by-step explanation:

To find the required gallons of gas for 30.10$, you can use the following formula:

Required gallons of gas=Cost of required gallons of gas/cost of one gallon of gas

Here given that, the cost of required gallons of gas is 30.10$ and the cost of one gallon of gas is 2.15$

Now apply the formula:

Required gallons of gas = 30.10$/2.15$ = 14

Therefore, the required gallons of gas = 14

So 14 gallons of gas costs 30.10$

Option D is the correct answer.

The graph demonstrates the relationship, and it indicates that the machine can produce 1200 soda bottles every minute.

The unitary technique is sometimes useful for multiplying and dividing by fractions because it makes sense immediately and can be done mentally if the numbers add up. This makes it a good method for defending or explaining frequently employed written fractional algorithms, like division by a fraction. The unitary technique has a formula that involves finding the value of a single unit, multiplying it by the quantity of units, and then finding the desired value.

given

y=20x

The total number of bottles produced in the specified amount of time, expressed in seconds, is represented by y.

When x=1 and y=20, the machine can produce 20 soda bottles each second.

There are 60 seconds in a minute, thus when x=60, y=20*60 equals 1200 drink bottles.

The perimeter of a rectangle is given by the formula P = 2(L + W), where P is the perimeter, L is the length, and W is the width.

We know that the perimeter of the parking lot is 354 m, and the width of the parking lot is 83 m. We can use this information to find the length of the parking lot.

Substituting the known values into the formula, we get:

354 = 2(L + 83)

Simplifying the equation:

354 = 2L + 166

Subtracting 166 from both sides:

188 = 2L

Dividing both sides by 2:

L = 94

The length of the parking lot is 94 m.

Answer:

Step-by-step explanation:

Formula for perimeter = (2 * length) + (2* width) = Perimeter

2l + (83 * 2) = 354

2l + 166 = 354

2l = 354 - 166

2l = 188

l = 188/2

l = 94 m

Answer:

A) 14

Step-by-step explanation:

When a small is gear connected to a larger gear, the smaller gear makes more revolutions than the larger gear. Use the ratio of the numbers of teeth to find the ratio of the numbers of revolution.

1 gear has 9 teeth

1 gear has 27 teeth

27/9 = 3

The ratio is 3:1.

The small gear makes 3 revolutions for each revolutuion of the large gear.

The large gear makes 1/3 revolution for each revolution of the small gear.

Here, the small gear makes 42 revolutions.

42/3 = 14

The large gear makes 14 revolutions.

Answer: A) 14

The larger gear has made 14 revolutions when the smaller gear has made 42 revolutions. This is because the ratio of the teeth on the gears is 1:3, which is also the ratio of their revolutions.

The ratio of the number of teeth on the two gears is also the ratio of the number of rotations they make. In this case, the smaller gear has 9 teeth and the larger gear has 27 teeth. So, the ratio is 9:27, which simplifies to 1:3.

This means that for every one rotation of the larger gear, the smaller gear will make three rotations.

Since the smaller gear has made 42 rotations, to figure out the number of rotations the larger gear has made, you would divide 42 by 3. (because of the 1:3 ratio). The answer is 14.

Therefore, the larger gear has made 14 revolutions when the smaller gear has made 42 revolutions. So, the correct answer is A) 14.

Therefore , the solution of the given problem of triangle comes out to be a=6 and b=17.

An triangle is a polygon since it has four or more parts. It is a simple geometric shape. A square having angles A, B, and C is referred to as a triangle ABC. When the sides are not collinear, Euclidean geometry generates a single plane and square. If a triangle has three sides and three corners, it is a polygon. The corners of a triangle are where its three sides meet. The sum of the angles in a triangle is 180 degrees.

Here,

Given : A right triangle ,

=> 8²+a²= 10²

=> a² = 100 -64

=>  a² =36

Marcella would need to sell at least 40 office machines each month to earn at least $4,000.

To find the least number of office machines Marcella would need to sell each month to earn at least $4,000, we need to know the price of each office machine and the commission she receives for each sale.

We can use following formula:

Rearranging this formula to solve for the number of machines sold, we get:

Plugging in the values we know:

Number of Machines Sold = 4000 / (1000 x 0.1)

Number of Machines Sold = 4000 / 100

Number of Machines Sold = 40

If you have a grade of 54.96 and you take a summative test worth 80%, it would bring up your grade by the following calculation:

New grade = (54.96) + (80/100) * (100 - 54.96)

New grade = 54.96 + (0.8) * (45.04)

New grade = 54.96 + 36.032

New grade = 90.992

So, your new grade would be 90.992

It's worth noting that this calculation assumes that the summative test is worth 80% of your overall grade, and that your previous grade was 54.96 out of 100. If this isn't the case, the result will be different.

Janice donated 20 pants and 80 t-shirts of clothing to the Salvation Army.

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, Janice donates 100 items of clothing to the Salvation Army and the number of t-shirts were 4 times the number of pants.

Therefore, If the number of pants is 'x' then the number of t-shirts are '4x'.

So, x + 4x = 100.

5x = 100.

x = 20.

So, The number of pants are 20 and the number of t-shirts are 80.
