Alaska occupies 17.22% of the surface area of the United States. Rounding to the nearest whole number, we get 17%. Hence, the answer is:17%

We are given that the surface area of the United States is 3.797 million square miles and the state of Alaska occupies 655,400 square miles. We need to determine what percentage of the surface area of the United States is occupied by Alaska using ratios.To find the percentage, we need to first find the ratio of Alaska's surface area to the surface area of the United States. We can do this by dividing the surface area of Alaska by the surface area of the United States. That is,655,400 / 3,797,000 = 0.1722We can express this ratio as a percentage by multiplying by 100. That is,0.1722 × 100 = 17.22%

Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs

Answer:

y=11x

Step-by-step explanation:

we use formula y2-y1/x2-x1 with 2 of the order pairs

22-11/2-1

11/1

11 is the slope

We find y intercept by finding when x is equal to zero and we subtract 11 until we find the 0 x unit since it goes down 11 every time

When x is zero y is zero so we write it like this

Y=11x

The length of the longer side of the rectangle is: 5.21 cm

We are told that a quarter-circle is drawn onto one of the shorter sides of a rectangle.

The shorter side of the rectangle measures 4 centimeters.

Thus, radius of circle is 4 cm.

The area of the quarter circle is:

A = ¹/₄πr²

A = ¹/₄ * 3.14 * 4²

A = 12.56 square centimeters

Area of rectangle = 33.4 - 12.56

A = 20.84 square centimeters

Length of longer side = 20.84/4

the x values are also called the domain lets assume -4 0 4. this is substituted into the equation 3x - 2y > 2 to get the values in the y direction.

3x - 2 > y

y < 3x - 2

for x = -4

y < 3 * -4 - 2 = -14

for x = 0

y < 3 * 0 - 2 = -2

Step-by-step explanation:

GOOD LUCK WITH BRAINLY I HOPE I HELPED :)

The expressions demonstrates the distributive property is

3(-8 + 1) = 3(-8)+ 3(1).

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

We know the standard forms for distributive property as

For addition: a x (b+ c) = a x b + a x c

For Subtraction: ax (b- c)= a x b - a x c

1. 3+ 4+ 5 = 4 + 3 + 5 is Associative Property.

The angles are formed by a transversal and two parallel lines in the figure. By applying congruent angles and vertical opposite angle property, ∠1 ≅∠3 ≅ ∠5 ≅ ∠7; ∠2 ≅ ∠4 ≅ ∠6 ≅ ∠8. Therefore option B is correct.

Congruent angles are identical to each other and have the same measure. The angles formed by the transversal in corresponding corners are called corresponding angles and they are congruent.

Therefore, ∠1 ≅ ∠5, ∠3 ≅ ∠7----------(1)

At a vertex if two angles are opposite to each other, then they are vertically opposite angles, they are equal and congruent to each other.

Therefore, ∠1 ≅ ∠3, ∠5 ≅ ∠7----------(2)

Combining (1) and (2), we get:

∠1 ≅∠3 ≅ ∠5 ≅ ∠7

Average rate of change is the change in the function per unit in a given interval. The average rate of change from x = 5 to x = 7  is -4.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, The graph of y = f(x)

See attachment for the points on f(x) that links x = 5 to x = 7

The line segment is represented by a green line

To determine the average rate of change using the line segment; we have the following values.

When x = 5: y = 8

When x = 7: y = 0

So, the average rate of change (m) is:

m = Δy/Δx

Where:

Δy = y₂ - y₁

Δy = 0- 8

Δy = -8

Δx = x₂ - x₁

Δx = 7 -5

Δx = 2

So, we have:

m = Δy/Δx

m = -8/2

m = -4

Hence, the average rate of change from  x = 5 to x = 7  is -4

Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.

Comparing the two circles, the length of segment AD is 4 cm. On the first circle, the diameter is BAE is 8cm.

We should know that a circle is a figure in which all distances are equal from the center and the line from the center to the circumference is called radius.

The diameter is the line that passes through the center of the circle dividing the circle into two equal parts.

The given information are that the circles are the same

Diameter of the circles = 8cm

Radius = D/2= 8/2

Radius = 4 cm in each circle

Since the two circles shave the same diameter of 8cm and segments are different because the second has 3 segments while the first has 2 segments

The length of the segment AD = 4 because its from center to circumference that is radius

The first circle BAE is a diameter because it divides the circle into two equal halves

Therefore the length of segment AD is 4cm because it is a radius.

the diameter is BAE is 8cm.
