The area of the rectangle with 8 and 3 1/2 units is 28 sq. units.

The region occupied by a rectangle within its four sides or boundaries is known as its area. The area of a rectangle is determined by its sides. Essentially, the formula for area is equal to the product of the rectangle's length and breadth.

It is given that the length of the rectangle is 8 units and the breadth 3 1/2 units.

the area of the rectangle = length x breadth = 8 x 3 1/2 = 8 x 7/2 = 28 sq. units

So, the area of the rectangle is 28 sq. units.

Answer:

102 adults, 165 children

Step-by-step explanation:

Let a be the number of adults, and let c be the number of children. We set up and solve this system of equations:

a + c = 267---------> 7a + 7c = 1869

12a + 7c = 2379------->12a + 7c = 2379

-----------------------

5a = 510

a = 102, c = 165

Step-by-step explanation:

Percentages represent the fraction over 100.

Answer:

(-1, 3)

Step-by-step explanation:

We could imagine the point G and H are points on a straight line.

We know that:

Point G is at (-10, 14)

Midpoint at M (-4.5, 5.5)

To calculate the x coordinate of the mid-point, we suppose to subtract x coordinate of H from coordinate x of G, divide by 2 to get the x coordinate of the midpoint m, which is -4.5

To calculate the y coordinate of the mid-point, we suppose to subtract y coordinate of H from y coordinate of G, divide by 2 to get the x coordinate of the midpoint m, which is 5.5

Therefore, x coordinate of H:

(- 10 - x) / 2 = -4.5

-10 - x = -9

- x = 1

x = - 1

And y coordinate of H:

(14 - y) / 2 = 5.5

14 - y = 11

- y = -3

y = 3

The law that was illustrated by the following 0 + 12 m is the same as 12 m is addition of zero.

The addition of zero law can be described as the law that says that whenever a particular number is been added to zero then the result of that addition will be that particular number.

It should be noted that this Identity Law of Addition can be seen in the given example where zero is added to 12m which gives the result of 12m which implies that the particular number 12m is added to zero and it gives the particular number 12m as the answer.

Answer:

720

Step-by-step explanation:

Formula: P (n,r) = n! ÷ (n - r)!

n = Total number of objects in a set

r = The number of items you choose

Mark knows the account number includes the numbers 2,3,5,7,8, and 9. There are obviously 6 numbers in total in this set and 6 he must choose in order to have a 6 digit account number, which the problem also directly states he has.

That means P(n,r) = P(6,6)

!/Factorial = Product of all positive numbers less than or equal to the given positive number

Therefore, 6! = 1 x 2 x 3 x 4 x 5 x 6

P (n,r) = P(6,6) = 6! ÷ (6-6)! = 720

The number such that when 3/4of it is added to 3 whole number 1/2 the sum is the same as when 2/3 of it is subtracted from the 6 whole number 1/2 is 36/17

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as the one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator that is displayed below (or after) the line on which the numerator is shown. Compound fractions, complicated fractions, and the mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.

The numerator and denominator of the positive common fractions are both natural integers. The denominator tells how many of those equal parts make up single unit or fraction, whereas the numerator represents the number of equal parts. Since a whole can never be made up of zero parts, denominator cannot be zero.

Answer:

Find x first.

Since angle EOG = 90°,

x = 90 - 54 = 36°

Angle AOD = angle COB = 156° (vertically opposite angles)

y + 54 + 36 + 2y = 156

3y + 90 = 156

3y = 66

y = 22°

Answer:

43.2 inches

Step-by-step explanation:

Hello!

According to the question Miami Beach and similar coastal regions are experiencing sea levels at a rate of 12 inches every five years how many inches will the sea level rise in the next 18 years if this rate remains constant

Firstly find rate per year

In order to find rate per year, divide 12inches by 5

➟ 12/5

➟ 2.4

Lastly Multiply 2.4 by 18

➟ 2.4 • 18

➟ 43.2

So, The sea level rise in the next 18 years is 43.2 inches

SOLUTION:

If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the y- axis. This is because the bounding lines of the function are the lines y = x and y = -x. Thus, when a varies from -1 to 1, the graph gets farther from the y-axis.

Final answer ;

Based on the calculations, the length (L) of this rectangle is equal to 5 feet.

A rectangle can be defined as a type of quadrilateral in which its opposite sides are equal and all the angles formed are right angle.

Mathematically, the area of a rectangle can be calculated by using this formula:

A = LW

Where:

Given the following data:

Area of rectangle, A = 35 square feet.

Width of rectangle, W = (L + 2) feet.

Substituting the given parameters into the formula, we have;

35 = L(L + 2)

35 = L² + 2L

L² + 2L - 35 = 0

Solving the quadratic equation by using the factorization method, we have:

L² + 7L - 5L - 35 = 0

L(L + 7) - 5(L + 7) = 0

(L + 7)(L - 5) = 0

Therefore, the length (L) of this rectangle is equal to 5 feet since the dimension can not be negative.

Answer: F. $1.25

Explanation:

First, we need to find the probability of the coin landing faceup and facedown. We know that landing faceup is 3 times the probability of landing facedown. Since the highest probability is 1 (100%):

With this, we know that:

probability of the coin landing faceup = 3×0.25 = 0.75

probability of the coin landing facedown = 0.25

To find the expected value of each toss, we need to solve for the total of each value multiplied by its probability:

Therefore, the expected value of each toss of Coin C is $1.25

We will say that x is the salary before the raise, to calculate how much the salary grows, we just have to take the given percent from x, in this case, the payment increased by 4% (0.04 expressed in decimal form) then the increased amount would be x times 0.04.

Salary increase = x*0.04 = 0.04x

Adding 0.04 x to the original salary x (before applying the increase) we get the actual monthly salary, $2,496, then we can formulate the following expression:

Current salary = original salary + salary increase

2,496 = x + 0.04x

From this equation, we can solve for x like this:

1. Factoring x on the right side of the equation:

2,496 = x(1+0.04)

2. making the sum inside the parentheses:

2,496 = x*1.04

3. Dividing both sides by 1.04:

2,496 / 1.04 = x * 1.04 / 1.04

2400 = x

x = 2400

Then, Linda was making $2400 before the pay increase

The given functions are

r(x) = - 2x - 2

s(x) = x^2 + 2

To find s(r(4)), the first step is to substitute x = - 2x - 2 into s(x) = x^2 + 2. Thus, we have

s(r(x)) = (- 2x - 2)^2 + 2

s(r(x) = (- 2x - 2)(- 2x - 2) + 2

s(r(x) = 4x^2 + 4x + 4x + 4 + 2

s(r(x)) = 4x^2 + 8x + 6

Finally, we would substitute x = 4 into s(r(x) = 4x^2 + 8x + 2. Thus, we have

s(r(4)) = 4(4)^2 + 8(4) + 6

s(r(4)) = 64 + 32 + 6

s(r(4)) = 102

y = 11

EXPLANATION

wo lines are parallel if they have the same slope and diffenrent y-intercepts.

In this case, we have to write the equation of a line parallel to the line y = 8, which is a line with a slope of 0 - i.e. it is a horizontal line. Therefore, the equation of the line we have to find must have the same form - y equal to a constant. This constant is the y-coordinate of the point where the line must pass through, (-3, 11).

Hence, the equation of the described line is y = 11.
