the remainder is 58

Step-by-step explanation:

when you use long division and can't fit what you are dividing by into the number, that is your remainder.

Using it's concept, it is found that there is a 0.5 = 50% probability that one of the fair number cubes is a 1.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

The outcomes of the pair of cubes that result in a sum of 5 are as follows:

(1,4), (2,3), (3,2), (4,1).

Of those 4 outcomes, 2 involve a number 1, hence the probability is given by:

p = 2/4 = 0.5.

The time and electricians it would take the remaining 3 electricians 8 hours to complete the job if one electrician does not report.

More people to do a task means less time it will take.

Less people to do a task means more time it will take.

Thus, they are inversely related.

If x men take y time for a work,

We can define a constant as "Manpower" needed for doing that specific work.

Let we define:

Manpower needed for a work = y + y + y + .. + y = Time per man × count of men

Manpower needed for a work = xy

We are given that;

Number of electricians= 4

Number of hours= 6

Now,

We can use the formula:

workers × time = work

where "workers" is the number of electricians, "time" is the number of hours they work, and "work" is the amount of work done.

In this case, we know that 4 electricians can complete the job in 6 hours. So:

4 × 6 = work

work = 24

This means that the total amount of work required to complete the job is 24 "units".

Now, if one electrician doesn't show up, we have only 3 electricians to do the work. Let's call the time it takes for the 3 electricians to complete the job "t".

So we have:

3 × t = 24

Dividing both sides by 3, we get:

t = 8

Therefore, by work and time answer will be 3 electricians and 8 hours.

THe value of the expression using BODMAS rule is 26

The abbreviation BODMAS, which stands for "Brackets, Order of powers or roots, Division, and Multiplication," is followed by the BODMAS rule. A stands for addition and S for subtraction. According to the BODMAS rule, multi-step mathematical statements must be solved in the BODMAS order from left to right.

The order of operations, or BODMAS, is a method for carrying out operations in an arithmetic statement. Math is all about logic, and there are several established laws that help us with our calculations. BODMAS is one of the established rules for consolidating multiple operator expressions.

An expression or equation in mathematics has two parts:

A character known as an operator joins two integers to form an expression or equation. The four most often used operators in mathematics are addition (+), subtraction (-), multiplication (*), and division (*/*). Finding the solution to mathematical statements or equations with just one operator is usually rather easy.

The expression is 14 + 2 + 3(4) - (6-1-3) = 14 + 2 + 12 - 2 = 26

The true statement about the function is C. function f and function g are not inverse because f{g(x)} = g{f(x)} .

An inverse function or an anti function, which can reverse into another function.In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.

now the given functions are,

f(x) = √(2x + 2) and

g(x) = (x^2 -2)/2

Now,

f{g(x)} = f{(x^2 -2)/2}

         = √(2(x^2 -2)/2 + 2)

         = √ x^2 -2 + 2

f{g(x)} = √ x^2

f{g(x)} =  x

Now,

g{f(x)} = g{ √(2x + 2)}

         = (√(2x + 2)^2 -2)/2

         = (2x + 2) -2 /2

         = 2x/2

f{g(x)} = x

Here we see that ,

f{g(x)} = g{f(x)}

Hence f and g are not inverses.

∴The true statement about the function is C. function f and function g are not inverse because f{g(x)} = g{f(x)} .

Answer:

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

As this is a right angle triangle.

using trigonometric identity:

tanA= Perpendicular/Base

In the given figure :

Perpendicular P= √5

Base B =O

so, Tan 30°= P/B

  1/√3 = √5/

doing cross multiplication we have:

 O= √5×√3

 O=√15

To find value of Hypotenuse, we will trigonometric identity:

Cos 30°= Base/ Hypotenuse

 √3/2 = √15/p

doing cross multiplication we get:

√3×p = √15×2

p = (√15 × 2)/ √3

p= (√5 × √3 × 2)/√3

p= 2√5

Hence, the Base is √15 and Hypotenuse p is 2√5.

For the given equation, when a is \(2\), the expression \(9-(7+3a)^2\) evaluates to \(-160\)

What is equation?

In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically contains variables, which are placeholders for unknown values that can take on different values.

In mathematics, an expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, and division.

According to given information:

The expression \(9-(7+3a)^2\) is a mathematical expression that involves an operation of squaring, subtraction, and addition.

Let's break it down step by step:

First, we have the expression (\(7+3a\)). This means we add \(7\) to \(3a\).

Then, we square the expression (\(7+3a\)) by multiplying it by itself. This gives us \((7+3a)^2.\)

Next, we subtract the result of the squared expression from \(9\). This gives us \(9 - (7+3a)^2.\)

In other words, \(9-(7+3a)^2\) is equivalent to subtracting the square of \(7+3a\) from \(9\).

For example, if a is \(2\), then we have:

\((7 + 3a) = (7 + 3(2)) = 13\\\\(7 + 3a)^2 = (13)^2 = 169\\\\9 - (7+3a)^2 = 9 - 169 = -160\\\\\)

Therefore, when a is \(2\), the expression \(9-(7+3a)^2\) evaluates to \(-160\)

Hence, He had to pay $ 18.11 for the tip on a restaurant bill.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Josiah ate dinner at a restaurant and his bill was $15.75,

He wanted to leave  15% tip,

Then He had to pay,

=15.75+15 % of 15.75

=15.75 + 0.15*15.75
