Why do elephants have ivory tusks?

Answers

Answer 1

Cause god made it that way lol

Answer 2

Elephants have ivory tusks, which are elongated incisor teeth, primarily for digging, stripping bark, and defense, and they may have evolved for sexual selection and competitive interactions among males.

Elephants have ivory tusks because they are actually elongated incisor teeth. These tusks are composed of dentine and are covered by a layer of enamel, just like our teeth. Elephants use their tusks for various purposes, such as digging for water, stripping bark from trees, and as a weapon for defense. However, the primary reason they have tusks is not entirely understood. It's believed that tusks might have evolved for sexual selection and display, as well as for competitive interactions among male elephants.

Write an equation of the line that is perpendicular to y = −4x + 8 and passes through the point (5, 1)

Answers

Hello,

To start, we have to identify the slope of the perpendicular line. Perpendicular lines have opposite reciprocal slopes. Therefore, the slope of our new line will be 1/4.

Now, just substitute in the given point with our new slope and we can solve for B.

y = (1/4)x + b
1 = (1/4)5 + b
1 = 5/4 + b
-1/4 = b

Now that we have the slope and the y-intercept, we can put together our equation.

It is: y = (1/4)x - 1/4

if a=37 degrees and b=6, find a.
A. 3.4
B. 4.5
C. 6.1
D. 2.5

Answers

To find the value of 'a' when a = 37 degrees and b = 6, trigonometry principles are used to calculate 'a' as approximately 34.08 degrees.

Given: a = 37 degrees and b = 6. To find a.

Using trigonometry: We can use the trigonometric ratio tangent to find a. tan(a) = b/c, where c is the hypotenuse. So, tan(37) = 6/c. Therefore, c = 6/tan(37) = 8.37. Hence, a = tan-1(b/c) = tan-1(6/8.37) ≈ 34.08 degrees.

Answer: Therefore, a = 34.08 degrees.

Divide £24.50 in the ratio 3:4

Answers

Step 1: Add the ratios

Step 2: Divide the money to be shared by the answer (this gives you the value of 1 share)

Step 3: Multiply the value of 1 share by each bit of the ratio

the answer is the £24.50 in the ratio 3:4 is £10.50:£14.00.

Final answer:

24.50 divided in the ratio 3:4 gives £10.50 and £14.00.

Explanation:

To divide £24.50 in the ratio 3:4, you first need to add the parts of the ratio together, which gives you 3 + 4 = 7 parts in total.

Then, you should divide the total amount of money by the total number of parts to find the value of one part.

In this case, £24.50 ÷ 7 = £3.50 per part.

Since the ratio is 3:4, you multiply the value per part by the number of parts for each portion of the ratio.

For the first part of the ratio, you multiply £3.50 by 3, giving £10.50. For the second part, you multiply £3.50 by 4, giving £14.00.

Hence, £24.50 divided in the ratio 3:4 gives £10.50 and £14.00.

5.The total area of the two small circles will equal that of the large circle.
6.The total area of the two small circles will be one-half of the area of the large circle.

Answers

Answer:

The answer is: 1, 2, and 6

Step-by-step explanation:

Answer with Step-by-step explanation:

Diameter of larger circle=8

Diameter of smaller circles=4

We know that radius is half times the diamketer

and Area=πr² where r is the radius

Radius of larger circle=4

Radius of smaller circles=2

Area of larger circle=π×4²

=16π

Area of two smaller circles=2×π×2²

= 8π=one-half the area of larger circle

Area of one small circle=π×2²

=4π=one fourth the area of larger circle

Hence, the correct options are:

1.The radius of the large circle is 4.

2.The radii of the small circles are each 2.

6.The total area of the two small circles will be one-half of the area of the large circle.

Ms Hendricks is buying a rectangular piece of land that is 2/5 mile on one side and 5/6 mile on an adjacent side. What is the area of the piece of land. help me please I don't get this

Answers

Hi there!

To find the area of an object, we need to multiply the two sidelengths together.

2/5 × 5/6 = 10/30

Now, we simplify.

10/30 = 1/3

So, your answer is 1/3 miles squared.

Hope this helps!

Final answer:

To find the area of Ms. Hendricks' rectangular land, multiply the lengths of the sides (2/5 mile and 5/6 mile), resulting in an area of 1/3 square mile.

Explanation:

The area of a rectangular piece of land is calculated by multiplying the length by the width. For Ms. Hendricks' piece of land, which measures 2/5 mile on one side (length) and 5/6 mile on an adjacent side (width), you would calculate the area by multiplying these two dimensions together:

Convert the fractions to have a common denominator if needed.Multiply the numerators of the fractions to find the numerator of the area.Multiply the denominators of the fractions to find the denominator of the area.Simplify the fraction if possible to find the final area in square miles.

So, the calculation for the area would be:

(2/5) mile * (5/6) mile = (2*5)/(5*6) square miles = 10/30 square miles = 1/3 square mile.

Therefore, the area is 1/3 square mile.

how do I do identify calculate the area and perimeter for quadrilaterals

Answers

length times width for area and add all the sides up for perimeter

To calculate the area and perimeter of a quadrilateral, you need to know the shape of the quadrilateral and the lengths of its sides. The area can be calculated using different formulas depending on the shape, such as trapezoid, rectangle, parallelogram, or square. The perimeter is calculated by adding the lengths of all the sides.

To calculate the area and perimeter of a quadrilateral, we need to know the shape of the quadrilateral and the lengths of its sides.

1. Area:

Trapezoid: The area of a trapezoid can be calculated using the formula A = (base1 + base2) × height / 2, where base1 and base2 are the lengths of the parallel sides, and height is the distance between the parallel sides.Rectangle: The area of a rectangle is calculated by multiplying its length by its width, so A = length × width.Parallelogram: The area of a parallelogram is calculated using the formula A = base × height, where base is the length of one side and height is the perpendicular distance between the base and the opposite side.Square: The area of a square is calculated by multiplying the length of any side by itself, so A = side × side.

2. Perimeter:

Trapezoid: The perimeter of a trapezoid is calculated by adding the lengths of all its sides.Rectangle: The perimeter of a rectangle is calculated by adding the lengths of its four sides, so P = 2 × length + 2 × width.Parallelogram: The perimeter of a parallelogram is calculated by adding the lengths of its four sides.Square: The perimeter of a square is calculated by multiplying the length of one side by 4, so P = 4 × side.

------------------------------
d = 1/4x - 17

I just realized that this is not the answer you are looking for. It's an equation, not a value. Sorry about that.

Answer:
d = -9

Explanation:
The slope of the line can be calculated using the following formula:
slope = [tex] \frac{y2-y1}{x2-x1} [/tex]

We are given:
slope = [tex] \frac{1}{4} [/tex]
point (9,-8) representing (x1,y1)
point (5,d) representing (x2,y2)

Substitute with the givens in the above equation and solve for d as follows:
slope = [tex] \frac{1}{4} [/tex]
[tex] \frac{1}{4} [/tex] = [tex] \frac{d-(-8)}{5-9} [/tex]
[tex] \frac{1}{4} [/tex] = [tex] \frac{d+8}{-4} [/tex]
4(d+8) = -4
d + 8 = -1
d = -1 - 8
d = -9

Chris is twice as old as Don, and next year the sum of their ages will be four times as much as Don’s age last year. Find their present ages.

Answers

Answer:

Chris is 12 years old and Don is 6 years old.

Step-by-step explanation:

;)

The present age of Don is 6 years old and Chris age is 12 years.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let's denote Don's current age as x.

As Chris is twice as old as Don, Then, Chris's current age is 2x.

Next year, their ages will be x+1 and 2x+1 respectively.

The sum of their ages will be four times as much as Don’s age last year.

(x+1) + (2x + 1) = 4(x-1).

Expanding and solving for x:

3x + 2 = 4x - 4

x = 6

So, Don is 6 years old and Chris is 2×6 = 12 years old.

Hence, the present age of Don is 6 years old and Chris age is 12 years.

First Answer:
A)fails the vertical line test at (2,3) and (2,-2)

Second Answer:
B) not a function
=========================================

Further Explanation:

It is possible to pass a single vertical line through this red curve. So it is not a function because it fails the vertical line test. One specific line goes from (2,3) to (2,-2) but there are infinitely other lines to choose from. In order to pass the vertical line test, it must be impossible to pass a vertical line through more than one point on the curve. A function is where any given input leads to exactly one output. In the case of (2,3) and (2,-2), the input x = 2 leads to more than one output (y = 3 and y = -2) at the same time
