If the figure below is a regular polygon, find the value of x.
(9x - 18)

Answer:

x = 18

Step-by-step explanation:

Complementary means the angles add to 90

x + 4x = 90

5x = 90

5x/5 = 90/5

x = 18

The larger angle is 4*18 = 72

Answer:

240 lbs

Step-by-step explanation:

Each gorilla eats a total of 40lbs (found that by dividing the number of gorillas by the pounds, 4/160, which is 40.)

So now that you know the number of pounds for each gorilla, you multiply the pounds by your gorillas ( 40 * 6, which is 240)

Hope this helps!

Answer:

240 he would need 240 to feed 6 gorillas every day

Answer:

divide 2 by 9

the result is 0.2 (repeats so need a bar over the 2) is a repeating decimal.

divide 3 by 10

the result is 0.3, is a terminating decimal.

both are rational and real numbers

Answer:

To change 2/9 to a decimal, divide 2 by 9.

The result, 0.222..., is a repeating decimal.

To change 3/10 to a decimal, divide 3 by 10.

The result, 0.3, is a ____ decimal. (I don't know the answer choices, but it would be the one that is the decimal not repeating).

Both 2/9 and 3/10 are irrational numbers.

Answer:

20 ft

Step-by-step explanation:

area of square = (side)^2

area of square = 25 ft^2

(side)^2 = 25 ft^2

side = 5 ft since (5 ft)^2 = 25 ft^2

The side of the square measures 5 ft.

All around the square is the perimeter.

perimeter = 4 * side

perimeter = 4 * 5 ft

perimeter = 20 ft

Answer: 20 ft

[tex]\frac{-(-3)+/-\sqrt{(-3^2)-4(-16)} }{2}=\frac{3+/-\sqrt{9-64} }{2}=\frac{3+/-\sqrt{-55} }{2}=\frac{3+/-\sqrt{55i^2} }{2} =\frac{3+/-i\sqrt{55} }{2}[/tex]

Answer:

115 square yards

Step-by-step explanation:

yeah-ya....... right?

The area of the figure is 115 yd².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

A figure:

This can be assumed to have two rectangles and one square.

Two rectangles are equal with dimensions:
Length = 9 yd

Width = 5 yd

The square has side = 5 yd.

Now,

Area of the figure.

= 2 x area of rectangle + area of the square

= 2 x (length x width) + side²

= 2 x (9 x 5) + 5²

= 2 x 45 + 25

= 90 + 25

= 115 yd²

Thus,

The area is 115 yd².

Step-by-step explanation:

A good way to look at multiplying 11 is that the number, if it’s under 10, will then be two of that number. For instance, 4 x 11 = 44, 6 x 11 = 66, and so on and so forth.

Answer:

Not here.

Step-by-step explanation:

F. The converse of the conditional.

The converse would state the following:

"If it is January, then it is winter in the United States" (Original).

"If it is winter in the United States, then it is January" (Converse).

It is not true, as it can be December, January, or February during the winter season.

G. The inverse of the conditional.

The inverse would state the following:

"If it is January, then it is winter in the United States" (Original).

"If it is not January, then it is not winter in the United States" (Inverse).

Again, as the above states, the winter season encompasses more than just the month of January.

H. The contrapositive of the conditional.

The contrapositive would state the following:

"If it is January, then it is winter in the United States" (Original).

"If it is not January, then it is not winter in the United States" (Contrapositive).

Again, there is more than just January in the winter season.

Answer:

f(x) = 2x^2 - 3x + 1

Step-by-step explanation:

The root 1 is associated with the factor (x - 1).

The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)

The quadratic in question is f(x) = (x - 1)(2x - 1).  To write this in standard form, perform the indicated multiplication:

f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1

Answer:

Step-by-step explanation:

Given, 5:3 = 5 to 3

1. 40/5 (40 divided by 5) 8

(You would divide to know what to do next.

You would also divide by the 5 because the ratio of the cars are red to blue, and the question asks if there were 40 red cars, how many blue cars were there.)

2. Because 5 red cars grouped into 8 were 40, multiply 3 by 8.

3. 3 x 8 = 24.

Answer: 24.

Using a system of linear equation to represent the problem given, there are 12 incorrect answers given

Let :

We could create an equation thus:

5(c) - 3(40 - c) = 104

Expand

5c - 120 + 3c = 104

8c = 104 + 120

8c = 224

c = (224 ÷ 8)

c = 28

Number of incorrect answers = 40 - 28 = 12

Therefore, there are 12 incorrect answers

Answer:

The correct option is C. (x=2)

Step-by-step explanation:

Given

Length of the hypotenuse of the right angled triangle (h) = 2.5 cm

Length of one of the side (a) = 1.5 cm

Let the length third side be 'b' cm

By Pythagoras theorem

h² = a² + b²

Adding Values on both sides

⇒ (2.5)² = (1.5)² + b²

⇒ 6.25 = 2.25 + b²

⇒ 6.25 - 2.25 = b²

⇒ 4 = b²

⇒ √4 = b

⇒ 2 = b

⇒ b = 2
