What is the value of n?

Answer:

16 x 12 = 192

192 x 2 = 384

10 x 8 = 80, 80 divided by 2 = 40

40 x 2 = 80

10 x 16 = 160

Add all given areas:

384 + 80 + 160 = 624 cm2 is your answer.

A fraction is a piece of a whole. In math, the number is communicated as a remainder, in which the numerator is separated by the denominator. In a basic fraction, both are numbers. A perplexing fraction has a fraction in the numerator or denominator

A fraction is a numerical value that is a piece of a whole. It is assessed by partitioning a whole into a number of parts. For instance, ½ addresses half of a whole number or a thing.

Answer:

15x12=180 good luck

Step-by-step explanation:

15x12=180

If the normal price is x and the normal price is reduced by 12%

0.12x = 9 ⇒ x = 75

The normal price of the coat was £75 in the clothes shop.

The percentage is defined as a ratio expressed as a fraction of 100.

A clothing store is having a sale. Normal prices are discounted by 12% during the sale. In the sale, the price of a coat is decreased by £9.

We have to determine the normal price of the coat.

Let the normal price of the coat would be £x

We have to evaluate 12% of x = 9

So, 12% of x = 9

12%  is expressed as 12/100 in fractional form

⇒ (12/100)(x) = 9

12/100  is expressed as 0.12 in decimal form

⇒ (0.12)(x) = 9

⇒ x = 9/0.12

Apply the division operation, and we get

⇒ 75

Thus, the normal price of the coat was £75.

The first equation is incorrect.

The second equation is correct.

The third equation is correct.

Let's go through each equation and determine whether it is correct or incorrect:

(b²+7b-9)+(4b-6b²) = -8b² + 14b-9

To determine if this equation is correct, we need to simplify both sides and check if they are equal.

On the left side:

(b²+7b-9)+(4b-6b²) = b² - 6b² + 7b + 4b - 9 = -5b² + 11b - 9

On the right side:

-8b² + 14b - 9

Comparing both sides, we can see that -5b² + 11b - 9 is not equal to -8b² + 14b - 9. Therefore, the equation is incorrect.

(4a+6)-(3a²-9a+1)=-3a²+ 13a +5

Again, we need to simplify both sides of the equation and check if they are equal.

On the left side:

(4a+6)-(3a²-9a+1) = 4a + 6 - 3a² + 9a - 1 = -3a² + 13a + 5

On the right side:

-3a² + 13a + 5

Comparing both sides, we can see that -3a² + 13a + 5 is equal to -3a² + 13a + 5. Therefore, the equation is correct.

(12c-8c²)+(5c²- 10c) = -3c²+2c

Again, let's simplify both sides and compare them.

On the left side:

(12c-8c²)+(5c²- 10c) = 12c - 8c² + 5c² - 10c = -3c² + 2c

On the right side:

-3c² + 2c

Comparing both sides, we can see that -3c² + 2c is equal to -3c² + 2c. Therefore, the equation is correct.

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.

In base seven, we have the following conversions:

1 long = 1 unit

1 flat = 10 units

1 block = 10 flats

To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.

So, the fewest number of multibase blocks required would be 2 flats.

Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.

In base three, we have the following conversions:

1 long = 1 unit

1 flat = 3 units

1 block = 3 flats

To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.

So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

The measure of angle GPE, considering the two tangents that intersect, is given as follows:

m < GPE = 27º.

The two-secant theorem states that when two secant lines of a circle intersect at a point outside a circle, the measure of the angle of intersection is given by half the difference between the arc length of the far arc by the arc length of the near arc.

Hence the equation is given as follows:

y = (far arc - near arc)/2.

The parameters for this problem are given as follows:

Hence angle GPE is the angle of intersection of the two secant segments, given as follows:

m < GPE = (97 - 43)/2

m < GPE = 27º.

Step-by-step explanation:

Given

The Swings: h > 24 and h <48

The Twister: h> 42 and h < 60

First, we need to list out the range of values of both ride categories

The Swings: h > 24 and h <48 implies that:

h = 25, 26, 27,28,.......,47

The twister: h > 42 and h < 60 implies that

h = 43, 44, 45,. 46,..........., 59

Next, is to compare each height to the height categories above.

Tracey: h= 47 inches

47 inches can be found in both categories; hence, Tracey can ride on the swings and the twister

Mark: h= 70 inches

70 inches is out of range in both categories. Hence, Mark can't ride in any of the ride categories.

Marissa: h = 28 inches

28 inches can be found in the swings category; hence, Marissa can ride on the swings only.

Number of scoops allowed per student = 2

If we are to write the total number of scoops that all the students will recive in linear form:

let the total number represent y

A linear form has the form:

y = mx + c

In this question:

y = 2x

Since there is no constant, the c = 0

m= 2 scoops per person

x = number of persons

The constraint that can affect the equation is the number of scoops.

Since we are told each person will only have 2 scoops.

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.

The functions f(x) =  (x + 3)/2 and g(x) = 2x - 3 are inverse functions of each other.

The function is the mathematical statement that shows the relationship between one variable and other variable. If one variable is independent variable then other variable is dependent variable.

The functions are

f(x) = (x + 3)/2

g(x) = 2x - 3

The value of f(g(x)) = ((2x-3) + 3) / 2

= (2x - 3 + 3) / 2

= 2x / 2

= x

The value of g(f(x)) = 2( (x+3)/2) - 3

= (2x + 6)/2 - 3

= x + 3 -3

= x

Therefore, f(x) and g(x) are inverse function of each other
