Answer 1

Answer:

Answer:

B. $13.75.

Step-by-step explanation:

To find the bill for lunch before the tip was added, we can set up an equation using the given information.

Let's assume the bill for lunch is represented by the variable "x".

We know that Mrs. Chin paid a 20% tip on the bill, which is equivalent to 0.20x.

According to the question, the tip amount is $2.75.

So we can write the equation as:

0.20x = $2.75

To solve for x, we need to isolate it.

Divide both sides of the equation by 0.20:

x = $2.75 / 0.20

Simplifying this gives us:

x = $13.75

Therefore, the bill for lunch before the tip was added is $13.75.

A wheel has a circumference of 7 5/6 feet. How many times does it turn in 423 feet.

Answers

the length of one full turn is the same as it's circumference.

circumference x turns = total length

to find the number of turns, you have to divide total length by it's circumference.

423 / (7 5/6) = 423 / (47/6)
= 54

75/6=12.5
and it will rotate 33.84 times to complete 423 ft

Which of the following equations is an equation formed when completing the square on y 2 - 12y = -27?(y - 6) 2 = -27
(y - 6) 2 = 9
(y + 6) 2 = 9

Answers

Answer: The correct option is

(B) $(y-6)^2=9.$

Step-by-step explanation: We are given to select the equation that is formed when completing the square on the following equation :

$y^2-12y=-27~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We will be using the following formula :

$a^2-2ab+b^2=(a-b)^2.$

From equation (i), we have

$y^2-12y=-27\n\n\Rightarrow y^2-2* x*6=-27\n\n\Rightarrow y^2-2* x* 6+6^2=-27+6^2\n\n\Rightarrow (y-6)^2=-27+36\n\n\Rightarrow (y-6)^2=9.$

Thus, the required equation that is formed is $(y-6)^2=9.$

Option (B) is CORRECT.

Hello,

You should write y²-12y=-27 or y^2-12y=-27

y²-12y=-27
==>y²-2*6y+6²=-27+36
==>(y-6)²=9

What is the solution to this equation? X-7 = 18

A. X = 25
B. x= 35
C. x = 11
D. X = 9

Answers

Answer:

Step-by-step explanation:

x - 7 = 18

Adding 7 to both sides (to get rid of the -7 on the left side) gives us:

x - 7 + 7 = 18 + 7

x = 25

Answer:

25 is the correct answer

Determine the value of A1 withreason/s

Answers

Answer:A1 = a If A1 represents a variable in an equation, we need the equation and any additional information to solve for its value. Once we have the equation and any given values, we can substitute those values into the equation and solve for A1. Without more context or information, it is not possible to determine the value of A1. If you can provide the equation or any additional details, I will be able to help you further in determining the value of A1.

Joseph drove for hours at the speed of 40 km per hours he changed his speed to 65 km for the next 2 hours how far had Joseph driven in km

Answers

Answer:

The answer to your question is 450 km

Step-by-step explanation:

Data

First stage Second stage

speed 1 = 40 km/h speed 2 = 65 km/h

time 1 = 8 h time 2 = 2 h

Process

1.- Write the formula to calculate the speed

speed = distance / time

-Solve for distance

distance = speed x time

2.- Calculate the distance of the first stage

distance 1 = 40 x 8

distance 1 = 320 km

3.- Calculate the distance of the second stage

distance 2 = 65 x 2

distance 2 = 130 km

4.- Calculate the total distance

Total distance = 320 + 130

= 450 km

Answers

A fraction which represents the ratio 9 to 6 in simplest form is $(1)/(2)$ .

Given the following data:

Numerator = 9.

Denominator = 6.

What is a fraction?

A fraction is a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.

The parts of a fraction.

In Mathematics, a fraction comprises two (2) main parts and these include:

Numerator

Denominator

Next, we would divide the numerator by the denominator as follows:

$Ratio = (9)/(6)$

Simplifying further by dividing both sides by 3, we have:

$Ratio = (3)/(2)$
