Answers

Answer 1

Answer:

x = -6

Step-by-step explanation:

30 = -5x

30/-5 = -5x/-5

-6 = x

Divide 30 by -5 to solve for x

Answer 2

Answer:

Divide both sides by -5.

x = 30/-5 = -6

bill is $75. tip is 18% what is the total bill

Answers

Answer:

Total bill = $88.50

Step-by-step explanation:

Amount of bill = $75

Tip = 18%

Amount of tip = [tex]\frac{18}{100}*75[/tex]

Amount of tip = [tex]0.18 * 75[/tex]

Amount of tip = $13.50

Total bill = Bill + Tip

Total bill = 75 + 13.50

Total bill = $88.50

18% of 75 is 13.5 and 13.5 plus 75 is 88.50. Therefore the total is $88.50

Answers

276-534 = -258
x = -258

Answer:

x=−258

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+534=276

Step 2: Subtract 534 from both sides.

x+534−534=276−534

x=−258

The value of the expression [tex]log_b(4b) = 3.[/tex]

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use logarithmic rules to solve this problem.

First, we know that log_b(8) = 3.

Using the definition of logarithms, this means that b³ = 8.

Solving for b, we find that b = 2.

Next, we know that log_b(0.5) = -1.

Using the definition of logarithms, this means that b^(-1) = 0.5.

Solving for b, we find that b = 2.

Since both expressions have the same base, we can use the logarithmic rule that states log_b(xy) = log_b(x) + log_b(y) to simplify log_b(4b) as follows:

[tex]log_b(4b) = log_b(4) + log_b(b)[/tex]

We can use the logarithmic rule that states:

log_b(b) = 1 to simplify log_b(b):

[tex]log_b(4b) = log_b(4) + 1[/tex]

Now, we can use the logarithmic rule that states:

[tex]log_b(x) = log_c(x)/log_c(b)[/tex]

To convert log_b(4) to a base 2 logarithm:

[tex]log_b(4) = log_2(4)/log_2(b) = 2/1 = 2[/tex]

Substituting this into the expression we found earlier, we get:

[tex]log_b(4b) = log_b(4) + 1 = 2 + 1 = 3[/tex]

Therefore,

[tex]log_b(4b) = 3.[/tex]

Hope this helps

Option B is correct, No, j = 9 is not a solution to the inequality j+1>10.

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

We can substitute j = 9 into the inequality j + 1 > 10 and see if it is true or false.

j plus one greater than ten.

j + 1 > 10

We have to check whether j=9 is the solution of the given inequality.

Substitute j equal to 9 in the above inequality.

9 + 1 > 10

10 > 10

The inequality is not true when j = 9. Therefore, j = 9 is not a solution to the inequality.

Hence, Option B is correct, No, j = 9 is not a solution to the inequality j+1>10.

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors

Answers

Complete question :

In a class of 125 students, 27 are computer science majors, 51 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major.

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

Answer:

0.039

Step-by-step explanation:

Total = T = 125

Computer Science = S = 27

Mechanical Engineering = M = 51

Civil Engineering = C = 12

General engineering, G = 125 - (27 + 51 + 12) = 35

Probability that none out of six chosen at random are Mechanical Engineering major :

Probability = required outcome / Total possible outcomes

Non mechanical engineering majors = 125 - 51 = 74

Probability none of 6 selected are mechanical engineering majors :

74C6 / 125C6

Recall :

nCr = n! / (n-r)! r!

, using calculator :

74C6 / 125C6 = 185250786 / 4690625500

Walter buys 5 large boxes of oat porridge and some small ones too.
In total, he buys 4175g of porridge.
Work out the number of small boxes of oat porridge Walter buys.
Note: Make your final answer clear by writing ... small boxes.
Total marks: 3

Answers

Answer:

3 boxes of small porridge

Step-by-step explanation:

625g x 5 = 3125

4125-3125=1000

1000 divided by 350 = 2.8

so there will be 2 full boxes of small porridge and 1 not full box of porridge.

Walter buys 3 small boxes of oat porridge.

What is an expression?

When used to represent a quantity or a mathematical relationship, symbols and/or numbers are combined to form an expression in mathematics. It may contain exponents, brackets, variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.

To begin, let's determine how much porridge is contained in the five enormous boxes:

5 x 625 = 3125g

Determine how much porridge is contained in the little boxes since we know that Walter purchases 4175g in total.

4175 - 3125 = 1050g

Assuming that there are 350g of porridge in each small box, we can calculate the number of small boxes by dividing the total weight of the porridge by the weight of each small box:

1050 / 350 = 3

Therefore, Walter buys 3 small boxes of oat porridge.
