Thus, from the all given expressions, the number of servings Riley will ve using is 15/2 ÷  3/4.

Once kids have a firm grasp on proper fractions, they are introduced to mixed numbers and incorrect fractions. A mixed number combines an integer (whole number) and a fraction. It is also sometimes referred to as a mixed fraction (part of a whole number).

The composite number's fractional component needs to be a legal fraction (less than one whole). The numerator (top number) of a correct fraction is less than its denominator (bottom number),

Given data:

Convert the mixed fraction 7 1/2 in the proper fraction:

= 7 1/2

= (7*2 + 1)/2

= 15/2

Number of serving cups =  Total amount of salsa / Serving cup size

Number of serving cups =  15/2 ÷  3/4

Thus, from the all given expressions, the number of servings Riley will ve using is 15/2 ÷  3/4.

Answer:

The speed of the helicopter is 160mph.

Step-by-step explanation:

The speed of the helicopter is 160mph.

Speed

Speed =Distance/Time

450miles/s-35mph = 702miles/s+35

450×s+35 = 702×s-35

450s+15,750 = 702s-24,570

Collect like terms

702s-450s = 15,750 + 24,570

252s= 40,320

Divide both side by 252s

s= 40,320/252

s= 160mph

Inconclusion the speed of the helicopter is 160mph.

Finding the total volume of a composite figure requires breaking it down into simpler shapes and then adding up their volumes.

To find the total volume of a composite figure, you'll need to break it down into simpler shapes and calculate their individual volumes.

Then, you can add up these volumes to get the total volume of the composite figure.

Here are the general steps you can follow:

Identify the simpler shapes: Look for the individual shapes that make up the composite figure, such as cubes, rectangular prisms, pyramids, cylinders, or spheres.

Calculate the volume of each shape: Use the appropriate formula for each shape to find its volume. For example, the volume of a cube is calculated by multiplying the length, width, and height of the cube.

Add up the volumes of all the simpler shapes: Once you have found the volume of each simpler shape, add them up to get the total volume of the composite figure.

Adjust for overlapping shapes: If there are any overlapping shapes, subtract the volume of the overlapped portion to avoid double-counting.

Check your work: Double-check your calculations and make sure your final answer makes sense based on the dimensions of the composite figure.

Overall, finding the total volume of a composite figure requires breaking it down into simpler shapes and then adding up their volumes.

67/12 cups of rice

Step-by-step explanation:

We Know

Jayden has 8 5/6 cups of rice.

8 5/6 = 53/6

He uses 3 1/4 cups to make dinner.

3 1/4 = 13/4

How many cups of rice does Jayden have left?

So, Jayden has  67/12 cups of rice left.

The value of the bond is multiplied by the factor [tex](1 + 0.04)[/tex], which is the same as multiplying by 1.04. After t years, the value of the bond will be multiplied by this factor t times, giving the formula:

[tex]100(1.04)t[/tex].

So, the value of the bond after t years is given by 100 • 1.04t.

A factor in mathematics is an expression or number that divides another expression or number without producing a residue. In other terms, a factor is a unit of measurement that may be multiplied by another unit of measurement to yield a specific outcome.

For example, 2 and 3 are factors of 6, because 2 multiplied by 3 equals 6. Similarly, (x + 1) and (x - 3) are factors of the expression [tex]x^2 - 2x - 3[/tex], because when these factors are multiplied together, they produce the expression:

[tex](x + 1) \times (x - 3) = x^2 - 2x - 3[/tex]

The bond is worth $100 initially, and it grows in value by 4% each year. This means that after one year, the value of the bond will be:

[tex]100 + 0.04(100) = 100(1 + 0.04) = 100(1.04)[/tex]

In other words, the value of the bond after one year is the initial value (100) multiplied by a factor of 1.04.

Similarly, after two years, the value of the bond will be:

[tex]100(1.04) + 0.04(100)(1.04) = 100(1.04)^2[/tex]

After three years, the value of the bond will be:

[tex]100(1.04)^2 + 0.04(100)(1.04)^2 = 100(1.04)^3[/tex]

In general, after t years, the value of the bond will be:

a. The probability that a randomly selected American who moved in 2004 was an owner is 0.31. b. 0.38 c. 0.03 .

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. For example, the probability of flipping a fair coin and getting heads is 0.5, because there are two equally likely outcomes (heads or tails).

a. Probability that a randomly selected American who moved in 2004 was an owner:

Total number of Americans who moved in 2004 = (11.7 + 2.8 + 0.3 + 18.7 + 4.5 + 1.0) million = 38 million

Number of Americans who moved in 2004 and were owners = 11.7 million

Therefore, the probability that a randomly selected American who moved in 2004 was an owner is:

11.7 million / 38 million = 0.31 (rounded to the nearest hundredth)

b. Probability that a randomly selected American who moved in 2004 moved within the same state:

Total number of Americans who moved in 2004 = (11.7 + 2.8 + 0.3 + 18.7 + 4.5 + 1.0) million = 38 million

Number of Americans who moved in 2004 and moved within the same state = 11.7 million + 2.8 million

Therefore, the probability that a randomly selected American who moved in 2004 moved within the same state is:

(11.7 million + 2.8 million) / 38 million = 0.38 (rounded to the nearest hundredth)

c. Probability that a randomly selected American who moved in 2004 was a renter who moved to a different country:

Total number of Americans who moved in 2004 = (11.7 + 2.8 + 0.3 + 18.7 + 4.5 + 1.0) million = 38 million

Number of Americans who moved in 2004 and were renters who moved to a different country = 1.0 million

Therefore, the probability that a randomly selected American who moved in 2004 was a renter who moved to a different country is:

A restaurant borrows $15,700 for two months from a nearby bank. For this loan, the neighbourhood bank charges simple interest at a yearly rate of 10%. Suppose a month is one-twelfth of a year.

a) $218.06 in interest will be due after two months.

b) In the event that the restaurant doesn't pay, the balance due after two months is $15,918.06.

a) To find the interest that will be owed after 2 months, we first need to calculate the monthly interest rate:

r = (10%)/12 = 0.00833333...

We can use the formula for simple interest to find the interest owed:

I = Prt

where P is the principal (the amount borrowed), r is the interest rate per period, and t is the time in periods. Since the loan is for 2 months, we have t = 2/12 = 1/6 years.

Substituting the values, we get:

I = 15700 * 0.00833333... * (1/6) = 218.0555...

Rounding to the nearest cent, the interest owed after 2 months is $218.06.

b) The total amount owed after 2 months is the sum of the principal and the interest. Using the same values as above, we have:

The total amount owed = Principal + Interest

= 15700 + 218.0555...

= 15918.0555...

Rounding to the nearest cent, the amount owed after 2 months is $15,918.06.

Answer:

To find the sum of money that amounts to Rs- 3450 in 4 months at the rate of 4.5% per annum, we can use the formula for simple interest:

Simple Interest = (Principal * Rate * Time) / 100

Where,

Principal = the sum of money borrowed or invested

Rate = the rate of interest per annum

Time = the time period in years

Since the time period given is 4 months, we need to convert it to years by dividing it by 12:

Time = 4/12 years = 1/3 years

Now, we can plug in the given values and solve for Principal:

Simple Interest = (Principal * Rate * Time) / 100

3450 = (Principal * 4.5 * 1/3) / 100

3450 * 100 = Principal * 4.5 * 1/3

11500 = Principal * 1.5

Principal = 11500 / 1.5

Principal = 7666.67 (rounded off to two decimal places)

Therefore, the sum of money that amounts to Rs- 3450 in 4 months at the rate of 4.5% per annum is Rs- 7666.67.

STANDARD FORM is [tex]3x^2 + 24x + 32y + 192 = 0[/tex] ,parabola has a maximum point at its vertex, which is (2, -3).

to write the equation for the given parabola in standard form, we need to use the vertex form of the equation of a parabola, which is:

[tex]y = a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola and 'a' is the coefficient that determines the shape and direction of the parabola.

We know that the x-intercepts of the parabola are -2 and 6. This means that the parabola intersects the x-axis at these two points. Therefore, the roots of the quadratic equation are -2 and 6.

We also know that the y-intercept of the parabola is -48, which means that the point (0, -48) lies on the parabola.

Since the parabola is symmetric about the vertical line passing through its vertex, the x-coordinate of the vertex is the midpoint of the x-intercepts, which is (6 - 2)/2 = 2.

Therefore, the vertex of the parabola is (2, k), where k is the y-coordinate of the vertex.

Now we can use the vertex form

[tex]y = a(x - 2)^2 + k[/tex]

We need to determine the values of 'a' and 'k' to complete the equation.

Since the parabola passes through the point (0, -48), we can substitute x = 0 and y = -48 into the equation:

[tex]-48 = a(0 - 2)^2 + k[/tex]

-48 = 4a + k

Similarly, since the x-intercepts are -2 and 6, we can substitute x = -2 and x = 6 into the equation to get:

[tex]0 = a(-2 - 2)^2 + k[/tex]

0 = 16a + k

0 = a(6 - 2)^2 + k

0 = 16a + k

Solving these three equations for 'a' and 'k', we get:

a = -3/8 and k = -3

Substituting these values into the vertex form equation, we get:

[tex]y = (-3/8)(x - 2)^2 - 3[/tex]

Therefore, the equation for the parabola in standard form is:

[tex]3x^2 + 24x + 32y + 192 = 0[/tex]

This parabola has a maximum point at its vertex, which is (2, -3).

the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).

What is axis reflection ?

An axis reflection is a transformation in geometry that involves reflecting a point, a line, or an object across a given axis. In two dimensions, there are two axes of reflection: the x-axis and the y-axis.

When reflecting over the x-axis, all points stay in the same horizontal position but change their vertical position, so a point (x,y) is reflected to (x,-y).

When reflecting over the y-axis, all points stay in the same vertical position but change their horizontal position, so a point (x,y) is reflected to (-x,y).

Axis reflections can be used to transform geometric shapes such as polygons, circles, or lines. These transformations have important applications in various fields, including physics, engineering, computer graphics, and art.

To find the composition of transformations that map ABCD to EHGF, we first need to determine the individual transformations that are needed.

Reflecting over the y-axis will change the x-coordinates of the points, but leave the y-coordinates unchanged. So, to reflect over the y-axis, we negate the x-coordinates of the points.

The translation (x+4, y+7) will move each point 4 units to the right and 7 units up.

Therefore, the composition of transformations is:

Reflect over the y-axis by negating the x-coordinates:

A'(-2, 3), B'(-4, 2), C'(-4, 0), D'(-2, -1)

Translate by (4,7):

A''(2, 10), B''(0, 9), C''(0, 7), D''(2, 6)

Therefore, the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).
