a) One number is five more than another number and the sum of the two numbers is 55, what are the numbers?

10 candies treats is Kayla still keeping for herself when Kayla had twenty candies. Kayla gave her sister one-fifth of the candies.

Given that,

Kayla had twenty candies. Kayla gave her sister one-fifth of the sweets. She gave her pal 3/8 of the remaining funds.

We have to find how many treats is Kayla still keeping for herself.

We know that,

20 candies are in Kayla's candy collection.

The amount Kayla gave her sister was equal to 1/5 of 20.

= 1/5 ×20

= 4 candies

The number of sweets Kayla has left over after sharing them with her sister = 20-4 = 16 candies

From the leftover candies, the friend received 3/8 of 16 candies.

= 3/8 × 16

= 6 candies

Kayla has 16 candies left after subtracting 6 for herself.

= 10 candies.

Therefore, 10 candies treats is Kayla still keeping for herself when Kayla had twenty sweets. Kayla gave her sister one-fifth of the sweets.

Answer:

We can use trigonometry to solve this problem. The angle of elevation is the angle between the horizontal line and the line of sight from the observer to the top of the building.

We are given the angle of elevation (41°) and the distance from the observer to the building (60 feet).

We can use the tangent function to find the height of the building:

tan(41°) = height / 60

To find the height of the building we can multiply both sides of the equation by 60:

height = tan(41°) * 60

The height of the building is approximately 41.56 feet

By subtracting the sum of the two known angles from 180, we can find the measure of the unknown angle. In this example, the size of angle ABC is 105 degrees.

105 degrees

To find the size of angle ABC, use the formula 180 - (A + B) = C.

A = 30 degrees

B = 45 degrees

Therefore, C = 180 - (30 + 45) = 105 degrees

Therefore, the size of angle ABC is 105 degrees to the nearest degree.

To find the size of angle ABC, use the formula 180 - (A + B) = C. In this case, A = 30 degrees and B = 45 degrees. Therefore, C = 180 - (30 + 45) = 105 degrees. The size of angle ABC is then 105 degrees, rounded to the nearest degree. This can be useful when trying to calculate the measure of an angle in a triangle. Knowing the measure of the other two angles, you can use this formula to find the measure of the third angle. By subtracting the sum of the two known angles from 180, we can find the measure of the unknown angle. In this example, the size of angle ABC is 105 degrees.

The solution of the system of linear equations are,

1) (2.2, -1.4).

2) (1.33, 1)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, We have to given that;

Two lines, with their corresponding equations are given and we have to find the solution to the system of equations.

The given lines are:

Equation of Line 1 is,

⇒ y = - 7/4x + 5/2

And, This line passes through the points (0, 2.5) and (2.2, -1.4).

Equation of Line 2 is,

⇒ y = 3/4x - 3

And, This line passes through the points (0, -3) , (2.2, -1.4)

By looking at the graph/given data we have to find the solution of these linear equations as;

Remember that the solution of linear equations is an ordered pair, through which both the lines pass i.e. the point at which both the given lines intersect is the solution of the linear equations.

So, From the given data we can see that both the lines pass through one common point, (2.2, -1.4).

Since, both lines pass through this point, this means this is the point of intersection of the lines and hence there solution.

So, The answer to this questions is (2.2, -1.4)

For the second question;

The given equations are:

⇒ y = 1.5x - 1     .. (i)

⇒ y = 1              .. (ii)

Now, We can solve these equations by method of substitution.

So, Substituting the value of y from Equation 2, in Equation 1, we get:

1 = 1.5x - 1

1 + 1 = 1.5x

2 = 1.5x

x = 2/1.5

x = 1.33

And, y = 1

Thus, The solution of the given linear equations is, (1.33, 1)

Yes, 'Rounding to the nearest cent means to round off the amount to the hundredths place' is the correct definition for Rounding to Nearest Cent.

Rounding to the nearest cent is a method of rounding an amount to the hundredths place. This means that any decimal value will be rounded up or down depending on the value of the decimal point.

For example, if the value is 0.45, it will be rounded down to 0.00 and if the value is 0.55, it will be rounded up to 1.00. This method of rounding can be used in accounting, finance and other business calculations.

Rounding to the nearest cent is a common practice used to accurately estimate an amount. It involves rounding off the amount to the hundredths place, so if the number is something like 12.356, it would be rounded off to 12.36.

c) The area of the border can be represented by the polynomial expression 32x+2x².

What is a polynomial expression?

A polynomial expression is a mathematical expression that is a sum of terms, each term consisting of a constant coefficient multiplied by one or more variables raised to a non-negative integer power.

a.) Let x represent the width of the border. The length of the new garden space would be 24 feet + 2x (since the border is added to both the length and width). The width of the new garden space would be 16 feet + 2x (since the border is added to both the length and width).

length = 24 + 2x

width = 16 + 2x

b.) The area of the new garden space can be represented by the trinomial (24+2x)(16+2x) = (24*16) + (48x) + (4x^2)

c.) The area of the border can be represented by the polynomial expression 2x(16+x) = 32x + 2x^2.

The property states that when two vectors a and b are multiplied together, the result is equal to the negative of b multiplied by a. This can be shown by multiplying the components of both vectors and then multiplying the result by -1.

a×b = (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1)

= (−1) * (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1)

= − b × a.

The property a × b = − b × a states that when two vectors a and b are multiplied, the result is equal to the negative of b multiplied by a. This can be proven by first expanding the components of both vectors. For a vector a=(a1,a2,a3) and b=(b1,b2,b3), the expanded form of a×b is (a2*b3 - a3*b2, a3*b1 - a1*b3, a1*b2 - a2*b1). This can then be multiplied by -1 to get the expanded form of -b×a, which is (b2*a3 - b3*a2, b3*a1 - b1*a3, b1*a2 - b2*a1). Since this is equal to the original form of a×b, this proves the property.

The area between the graph of y=x^2-2 and the x-axis between x=0 and x=7 is calculated by first finding the area beneath the graph. This can be done by using the formula

A = ∫f(x)dx.

This integral is equal to

A = ∫(x^2-2)dx,

which when solved yields

A = (x^3/3)-2x.

Plugging in the values for x=0 and x=7 yields

A = (343/3)-(14)= 45.500.

To find the area between the graph and the x-axis, we subtract the area beneath the x-axis from the area beneath the graph. The area beneath the x-axis is 0, so the final answer is 45.500.This area is calculated by finding the area beneath the graph and subtracting the area beneath the x-axis.
