Answer:

Lake Eyre is higher by 242 meters.

Step-by-step explanation:

Jericho = -258

Lake Eyre = -16

-258 - (-16) = -242

Lake Eyre is 242 meters higher than Jericho below sea level.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The city of Jericho, in the Middle East, has the lowest elevation of any city on Earth. It is 258 meters below sea level,
Lake Eyre, the lowest point in Australia, is only 16 meters below sea level.
Difference in the elevation = 258 - 16 = 242

Thus, Lake Eyre is 242 meters higher than Jericho below sea level.

We can write this as

9×8×7×6×5×4×3×2×1=9!

. We can also write this as a permutation, with the general formula being:Pn,k=n(n−k

And so we'd get:

P9,9=9!(9−9)!=9!1=9!

Answer:
1. 1,314 in^2
2. 465in^2
3. 464in^2
4. 157.5in^2

Step-by-step explanation:

The steps to this is easy. since they give you the nets.
1. The formula for finding the surface area of a cuboid is 2(LB + LH + BH). Where L is the length, B is the breadth or width and H is the height. In this question, the length is 26 in, width is 17 in and height is 5 in. Therefore, the equation will be 2(26in(17in) + 26in(5in) + 17in(5in)). From there its simple application of the rules of BODMAS.

2. Since the net of this pyramid is given, the surface area is simply the area of the base plus the areas of all the individual triangular faces.

3.The net has been given so we apply the same method here. we find the area of the rectangular and the triangular faces and sum them up. ( For this question, it seems that there isnt any possible answer that matches mine. So I apologise for the inconvenience.)

4.We find the area of just one of the triangular faces and multiply it by 4 to get our answer.

Hope this helps

Step-by-step explanation:

Probability of dime:

There are 14 coins.

3 of which are dimes

you would put it over 14: 3/14 and cross multiply it with x/100

then you would get 300 and 14x

Divide 300 by 14 approximately 21. 4%

Probability of nickel:

There are 14 coins.

same thing as the top one,

you put 4/14 and times it by x/100

you get 400 and 14x

divide 400 by 14

and get about 27.7%

Answer:

X coordinate

Y coordinate

rectangle

Step-by-step explanation:

The  statements is true about the graph of these points is

The coordinates of the ordered pairs satisfy the equation .

The slope of a line is the measure of the steepness and the direction of the line. The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Slope = m = tan θ = (y2 - y1)/(x2 - x1)

where, m is the slope, and θ is the angle made by the line with the positive x-axis.

According to the question

The set of points (–3, 7), (0, –3) and (6, 1) are plotted in the coordinate plane.

Conditions which are true in options for set of points .

a> They do not represent a linear function.

A linear function is defined as a function that has either one or two variables without exponents.

This statement is false they do represent the linear function.

b>The slopes of the lines between each pair of points are equal.

slopes between (–3, 7), (0, –3)

Slope = (y2 - y1)/(x2 - x1)

Slope = (7 - (-3))/( (-3))

Slope = [tex]\frac{-10}{3}[/tex]

slopes between (0, –3) and (6, 1)

Slope = (y2 - y1)/(x2 - x1)

Slope = (1 - (-3))/(6- (0))

Slope = [tex]\frac{2}{3}[/tex]

Hence, this statement is false .

c>The first coordinate of each ordered pair is always less than the second coordinate.

This statement is false as in both ordered pair  (0, –3) and (6, 1)  first coordinate is bigger than second

d>The coordinates of the ordered pairs satisfy the equation .

This is true as ordered pairs satisfy the equation .

y = mx +c

Hence, the  statements is true about the graph of these points is

The coordinates of the ordered pairs satisfy the equation .
