The diagonal length of his current TV is 65 inches.

Pythagoras theorem states that for a right-angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude. It can be used to find the diagonal of a rectangle if we know the length and the width.

As per the given data:

Length of the TV (l) = 56 inches

Width of the TV (b) = 33 inches

To find the diagonal length (d) of the TV:

From Pythagoras theorem:

[tex]d = \sqrt{l^2 +b^2}\\d = \sqrt{(56)^2 +(33)^2}\\d = \sqrt{3136 +1089}\\d = \sqrt{4225}\\d = 65 inches[/tex]

The measure of x from the angles of the parallel lines are solved

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

In response to the aforementioned query, we may say that The future interest value of the loan, or the total amount due after three months, is $8140.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

The following formula can be used to determine a loan's future value A:

[tex]A = P + Prt[/tex]

When P is the principal borrowed, r denotes the interest rate in decimal form, and t denotes the length of time in years.

P equals $8,000, r equals 0.07 (because the interest rate is specified as 7%), and t equals 3/12 to 0.25 years in this example (since the time period is given in months and we need to convert it to years).

With these values entered into the formula, we obtain:

[tex]A = $8000 + $80000.070.25\\A = $8000 + $140 \sA = $8140[/tex]

The future value of the loan, or the total amount due after three months, is $8140.

Answer:

[tex](r \;\circ\;q)(4) = \boxed{5}\\\\(q \;\circ\;r)(4) = \boxed{13}\\[/tex]

Step-by-step explanation:

We have the following functions

[tex]q(x) = x^2+4\\\\and\\\\r(x) = \sqrt{x+5}\\\\[/tex]

1. To find
[tex](r \;\circ \;q)(4) = r(\;q(4)\;)[/tex]

First find
[tex]q(4) = 4^2 + 4 = 16 + 4 = 20[/tex]

Substitute this value for x in r(x)

[tex]r(20) = \sqrt{20 + 5} = \sqrt{25} = 5[/tex]

So
[tex]\bold{(r \;\circ \;q)(4) = 5}[/tex]

2. To find

Here we have the two functions:

q(x) = x² + 4

r(x)=  √(x + 5)

We want to find the two compositions:

(r o q)(4) = r(q(4))

First let's find:

q(4) = 4² + 4 = 16 + 4 = 20

Then:

r(q(4)) = r(20) =  √(20 + 5) = 5

And the other composition is:

(q o r)(4) = q(r(4))

To solve for x in the equation:

11.6% = x × 17.8% + (1 - x) × 8.4%

We can first convert the percentages to decimal form:

11.6% = 0.116

17.8% = 0.178

8.4% = 0.084

Substituting these values into the equation, we get:

0.116 = x  0.178 + (1 - x) × 0.084

Next, we can simplify the equation by distributing the (1 - x) term:

0.116 = x × 0.178 + 0.084 - x × 0.084

Simplifying further by combining like terms, we get:

0.116 = 0.178x + 0.084 - 0.084x

0.116 = 0.094x + 0.084

Subtracting 0.084 from both sides of the equation, we get:

0.032 = 0.094x

Finally, dividing both sides of the equation by 0.094, we get:

x = 0.3404 or approximately 0.34

Therefore, x is approximately 0.34

There are 37 pupils in the class.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, the ratio of girls to boys is 4:3, this means that for every 4 girls, there are 3 boys.

We can use this ratio to find the number of boys in the class. Let's set up a proportion:

4 girls : 3 boys = 21 girls : x boys

The solutions to the quadratic equation [tex]X^2 + 7X = 0[/tex] are X = 0 and X = -7.

What is quadratic equation?

A quadratic equation is a polynomial equation of the second degree, which means it contains one or more terms that are raised to the power of two. The standard form of a quadratic equation is:

[tex]ax^2 + bx + c = 0[/tex]

where a, b, and c are constants, and x is the variable. The value of x that satisfies the equation is called the root or solution of the quadratic equation.

Quadratic equations can have one, two, or no real solutions, depending on the value of the discriminant [tex]b^2 - 4ac[/tex]. If the discriminant is positive, the equation has two real solutions; if it is zero, the equation has one real solution; and if it is negative, the equation has no real solutions but two complex solutions.

To solve the quadratic equation [tex]X^2 + 7X = 0[/tex] by factoring, we first write it in the standard form:

[tex]X^2 + 7X = 0[/tex]

Next, we factor out the common factor X:

X(X + 7) = 0

Now, we can apply the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. In this case, we have:

X = 0 or X + 7 = 0

Solving for X in each equation, we get:

X = 0 or X = -7

Therefore, the solutions to the quadratic equation X^2 + 7X = 0 are X = 0 and X = -7.

We can say that approximately 4.29 inches of rain fell in 15 minutes.

We can apply a proportion to determine the amount of rain that fell in 15 minutes.

We can calculate the proportion because we know that 12 inches of rain fell in 42 minutes:

x inches in 15 minutes equals 12 inches in 42 minutes.

where x is how much rain fell in 15 minutes.

We can cross-multiply and simplify to find x's value:

42 minutes equals 12 inches times 15 minutes (x inches)

180 = 42x

x = 180 / 42

To convert a degree of likelihood to a probability value, we use the formula:

probability = number of favorable outcomes / total number of possible outcomes

In this case, the chances of encountering a car crash on the road are stated as "5 in 17", which means there are 5 favorable outcomes (encountering a car crash) out of 17 possible outcomes (driving on the road).

So, the probability of encountering a car crash can be calculated as:

probability = 5/17

This fraction can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case. Therefore, the probability of encountering a car crash on the road is:

probability = 5/17 ≈ 0.2941

Since the probability value is between 0 and 1 inclusive, we can express the indicated degree of likelihood as a probability value of approximately 0.2941.

The tenth place becomes 10 + 0 - 3 = 7.

89.600 - 47.131 = 42.469

Finally, subtract the hundredth place (9 - 1), which gives 8.
