The correct option regarding the number of bags filled by Nina, using proportions, is given as follows:

Between 20 and 30 bags.

A proportion is a fraction of an amount, and this fraction is combined with the unit rates of the problem and basic arithmetic operations, especially multiplication and division, to find the desired amounts in the context of the problem.

In this problem, a proportion is applied to find the number of bags filled by Nina, which is given by the division presented as follows:

Number of bags = Number of treats / Treats per bag.

The values of these parameters are given as follows:

Hence the numeric value of the expression is:

Number of bags = 78/3 = 26.

Which is a number between 20 and 30.

The problem states that Nina had 78 treats, and each bag has 3 treats, then it asks the correct option regarding the number of bags.

Yes, they make sense outside the context of temperature.

Step-by-step explanation:

If you are standing in a line, and mark your current position as 0 then if you take two steps ahead it can be counted as positive and if you take two steps back from your current position it can be counted as negative. The positive and negative can denote your forward and backward movement respectively.

If we denote the growth in companies revenue as positive and dip as negative then it would also make sense. A positive number would mean profit for the company while a negative sign would show loss.

Answer:

10 kg

Step-by-step explanation:

In 3% concentration of 20 kg of seawater, there will be \(\frac{20*3}{100}=0.6\) kg of salt.

So, if it is a 2% solution of seawater,

Then 2 kg salt will be there in 100 kg solution.

So, 0.6 kg salt will be there in \(\frac{100*0.6}{2}=30\) kg of solution.

So, to make a solution from 3% to 2% we have to add (30 - 20) = 10 kg of water with a 20 kg solution. (Answer)

500,000 + 7,000 + 20 + 1

Step-by-step explanation:

Answer:

The expanded form of 507,021 is 500,000 + 7,000 + 20 + 1.

Step-by-step explanation:

500,000 + 7,000 + 20 + 1

Explanation:

When writing numbers in expanded form, you are essentially breaking the number apart so that the value of every individual digit is shown.

Here are some examples of a number and its expanded form:

· 874,923 = 800,000 + 70,000 + 4,000 + 900 + 20 + 3

· 3,905 = 3,000 + 9,000 + 5

· 42,069 = 40,000 + 2,000 + 60 + 9

* note:

if the number you are going to write in expanded form includes a zero (ex: the number 42,069), you do not need to include the zero when writing each digits value. However, if you or your instructor prefers to include the value of zero, you may. To solve this problem, I will not be including the value of zero.

we understand what expanded form is, let's write 507,021 in expanded form.

Start by writing a list for the values of each individual digit:

· 500,000

· 7,000

· 20

· 1

Next, write the numbers so that they show they must be added.

500,000 + 7,000 + 20 + 1

Answer:

4.5in, 8in

Step-by-step explanation:

So, what is radius?

Well, diameter is the distance from one side of a circle to the other.

Radius is half of diamater, or the distance from any side to the middle of the circle.

Problem #1:

In this case, the distance from side of the circle to the other side is 9.

Since this is side to side, it must be diameter. We know that radius is half of diameter, so radius is:

9/2

=

4.5

This is your radius.

Problem #2:

In this case, the distance from the one side to the other side of the circle is 16. Again, this is the diameter. So the radius will be half of 16:

16/2

=

8

So this is your radius.

Hope this helps!

Answer:

4.5 in. and 8 ft. respectively

Step-by-step explanation:

The diameter of a circle is the product of the radius and 2. So, the radius would be the quotient of the diameter and 2.

Answer:

To form a rectangle, the piece of wire will have two sides of length x and two sides of length (18 - 2x)/2 = 9 - x. Therefore, the perimeter of the rectangle is given by:

2x + 2(9 - x) = 18 - 2x

The area of the rectangle is given by:

A = x(9 - x)

Expanding this expression, we get:

A = 9x - x^2

To find the dimensions of the rectangle with maximum area, we can differentiate the area expression with respect to x:

dA/dx = 9 - 2x

Setting this equal to zero to find the maximum:

9 - 2x = 0

x = 4.5

So, one side of the rectangle is x = 4.5 cm and the other side is (18 - 2x)/2 = 4.5 cm. Therefore, the dimensions of the rectangle with maximum area are 4.5 cm by 4.5 cm.

To calculate the maximum area, we can substitute x = 4.5 into the area expression:

A = 9(4.5) - (4.5)^2 = 20.25 cm^2

Step-by-step explanation:

Answer:

y = -16

Step-by-step explanation:

y = kx for proportion questions like this

y = kx

y = 64, x = -8

64 = -8k

Divide by -8 on each side

64/-8 = -8k/-8

-8 = k

Then to find y when x = 2, use y = kx again

y = kx

k = -8

x = 2

y = 2(-8)

y = -16

At x = 2 , the value of y will be ; y = -16.

It is given that y is directly proportional to the value of x and at x = - 8 , value of y is ; y = 64.

We have to calculate the value of y at x = 2.

What will be the value of y ; if x = 4 in equation x - y = 2 ?

The value of y will be , y = 2 .

Let's assume ;

y = k × x  ----- ------ ------ -------- ------ ----- ---- -------- Equation 1

It is given in the question that ;

at x = -  8 , y = 64

Putting these values in equation 1 to find the value of k.

⇒ 64 = - 8 × k

Dividing on both sides by - 8

⇒ k = - 8

Now , to find value of y at x = 2, we need to use equation 1 again ;

⇒ y = - 8 × 2

⇒ y = -16

Thus , at x = 2 , the value of y will be ; y = -16.

g(x) = x + 1

f(3) = x = 3

Step 2: Find f(3)

f(3) = 2(3)² - 3

f(3) = 2(9) - 3

f(3) = 18 - 3

f(3) = 15

g(15) = 15 + 1

g(15) = 16

g(f(3)) = 16

The number of Jim's model car is 48

From the question, we have the following parameters that can be used in our computation:

Ratio of the number of model cars that Jim owns to the number of model cars Terrence owns is 8 : 6

This means that

Jim : Terrence = 8 : 6

Also from the question, we have

Terrence owns 36 models cars

This means that

Terrence = 36

Substitute the known values in the above equation, so, we have the following representation

Jim : 36 = 8 : 6

Multiply by 6

Jim : 36 = 48 : 36

So, we have

Jim = 48

The measure of the inscribed angle G in the circle is 85 degree.

An inscribed angle is simply an angle with its vertex on the circle and whose sides are chords.

The relationhip between an an inscribed angle and intercepted arc is expressed as:

Inscribed angle = 1/2 × intercepted arc.

Since the circle equals 360 degrees, we can determine the intercepted arc DF.

Hence:

Arc DF = 360 - ( 70 + 120 )

Arc DF = 360 - 190

Arc DF = 170°

Now, plug the value into the above formula:

Inscribed angle = 1/2 × intercepted arc.

Inscribed angle G = 1/2 × 170°

Inscribed angle G = 85°

Therefore, angle G has a measure of 85 degree.

There are no solutions to the system of inequalities Option (d)

Inequalities are a fundamental concept in mathematics and are commonly used in solving problems that involve ranges of values.

A system of two inequalities is a set of two inequalities that are considered together. In this case, the system of inequalities is

y > 3x + 1

y < 3x - 3

The inequality y > 3x + 1 represents a line on the coordinate plane with a slope of 3 and a y-intercept of 1. The inequality y < 3x - 3 represents another line on the coordinate plane with a slope of 3 and a y-intercept of -3. We can draw these lines on the coordinate plane and shade the regions that satisfy each inequality.

The first line has a positive slope and goes through (negative 2, negative 5) and (0, 1). Everything to the left of the line is shaded. The second line has a positive slope and goes through (0, negative 3) and (1, 0). Everything to the right of the line is shaded.

We can start by analyzing the inequality y > 3x + 1. This inequality represents the region above the line with a slope of 3 and a y-intercept of 1. Therefore, any point that is above this line satisfies this inequality.

Next, we analyze the inequality y < 3x - 3. This inequality represents the region below the line with a slope of 3 and a y-intercept of -3. Therefore, any point that is below this line satisfies this inequality.

To determine which values satisfy both inequalities, we need to find the region that satisfies both inequalities. This region is the intersection of the regions that satisfy each inequality.

When we analyze the regions that satisfy each inequality, we see that there is no region that satisfies both inequalities. Therefore, there are no values that satisfy the system of inequalities shown.

There are no solutions to the system of inequalities y > 3x + 1 and y < 3x - 3 by analyzing the regions that satisfy each inequality on a coordinate plane. The lack of a solution is determined by the fact that there is no region that satisfies both inequalities.
