Answer:

4 participants

Step-by-step explanation:

The name of the chart is "Participants PER race"

That means they tall you how many people did the race now all you gotta do is, Count up the numbers more than 61- So look at the 6 in the "stem" portion

it has 67, 67 they are both more than 61

Then look at the next "stem" number- 7

that has 74 which is more than 61 but less than 85

Then we look at the 8 in the "stem" it has three numbers- 84, 86, 89

but 86 and 89 are more than 85 so 84 is the only one which will go through

So the numbers are: 67, 67, 74, and 84

Thus 4 participants

I hope this explained it!

Answer:

Step-by-step explanation:

Given a parallelogram with points

X(4, 0)

W(0, -1)

Y(3, -2)

Z(-1, -3)

We want to find the perimeter, perimeter is the total sum of the lengths

So, we need to find the length of the sides using distance between two points

D = √(x2-x1)² + (y2-y1)²

So, applying this

WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17

XY = √(4-3)² + (0--2)² = √(1+4) = √5

Since the opposite sides of a parallelogram are equal, we don't need to find the other length

Then,

Perimeter = 2(WX + XY)

Perimeter = 2(√17 + √5)

Perimeter = 2√17 + 2√5

The correct answer is B.

Step-by-step explanation:

i don't know the exact name of the last two but that's what i'm assuming they're called lol

The properties used to solve the equation 4(x + 3) = 20 are the distributive property, subtraction property of equality, and division property of equality. First, the distributive property is used to expand the left-hand side, then subtraction is used to isolate 4x. Finally, division is used to find x = 2.

The question provides an algebraic equation and uses properties to solve for the variable 'x'. The steps taken demonstrate the following properties:

Answer:

The only difference is: If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

Answer:yes they are different

Step-by-step explanation:

1. An equation is an equality of two mathematical expressions. That's why it has an equal(=) sign . For example:

12x=10x +2x

Or

3x+4y=5

2. While an inequation is an inequality of two expressions and here the greater than and lower than signs are used with equal sign i.e. >,< or=

For example

4y+5a > 5

Or

8a< 7b

Work Shown:

a = x, b = 3, c = 4

a^2 + b^2 = c^2  ... pythagorean theorem

x^2 + (3)^2 = (4)^2

x^2 + 9 = 16

x^2 = 16 - 9

x^2 = 7

x = sqrt(7)

x = 2.64575131106459

x = 2.6

In a right triangle with one leg of length 3, the other leg of length 4, and the hypotenuse of length x, the Pythagorean theorem formula (3² + 4² = x²) gives the length of x as √25, or 5 units.

In Mathematics, a right triangle has one angle that is a right angle (90 degrees). In these triangles, the Pythagorean theorem applies, which says that the square of the length of the longest side (hypotenuse) is equal to the sum of squares of the other two sides (legs).

If x is a leg of the triangle, then its length can be found by rearranging the Pythagorean theorem formula. If the length of one leg is 3, the other is 4, and the length of the hypotenuse is x, then the equation is: 3² + 4² = x².

That simplifies to 9 + 16 = x², and further to x² = 25. Taking the square root of both sides gives us the length of x as 5 units.

Let w represent width of the pathway.

We have been given that a rectangular garden measuring 13 meters by 15 meters is to have a gravel pathway of constant width built all around it.

Since pathway will be on all sides, so new length and width of garden with pathway would be [tex]13+2w[/tex] by [tex]15+2w[/tex].

We are also told that there is enough gravel to cover 80 square meters. This means that area f pathway should be equal to 80 square meters.

The area of the pathway will be equal to area of garden with new dimensions minus area of garden with original dimensions.

We know that area of rectangle is width times length.

[tex]\text{Area of pathway}=(15+2w)(13+2w)-15(13)[/tex]

Since we are asked to write an inequality that represents all possible widths(w), in meters, of the pathway, so area of pathway should be less than or equal to 80 square meters.

[tex](15+2w)(13+2w)-15(13)\leq 80[/tex]

Therefore, our required inequality would be [tex](15+2w)(13+2w)-15(13)\leq 80[/tex].

Answer:

13 units

Step-by-step explanation:

Use the pythagorean theorem and find the hypotenuse.

a^2 + b^2 =c^2  

Draw the triangle by connecting the dots so you can see the legs.

one leg is 8 units and one leg is 10 units

8^2 + 10^2 = c^2

64 +100= c^2

164 = c^2

Answer:

Step-by-step explanation:

The ratio 20:40:60 is simplified by dividing each number by the greatest common divisor (GCD), which is 20, giving us the simplest form of the ratio as 1:2:3.

To write a ratio in simplest form, you have to find the greatest common divisor (GCD) of the numbers and then divide all numbers by the GCD. In the ratio 20:40:60, the GCD is 20. Therefore, when you divide each number of the ratio by the GCD you get 1:2:3. So, the ratio 20:40:60 in its simplest form is 1:2:3.

Step-by-step explanation:

Missing question:

An artist is making a rectangular canvas for a custom painting. the canvas has a width of 9 1/2 feet and a length of 13 1/4 feet . what is the area of canvas in square feet?

The area of a rectangle is given by the formula

[tex]A=L\cdot w[/tex] (1)

where

A is the area

L is the length

w is the width

In this problem, we have a rectangular canvas, so we want to find its area.

We know that:

[tex]w=9\frac{1}{2}ft[/tex] is the width, converting into an improper fraction,

[tex]w=\frac{9\cdot 2+1}{2}=\frac{19}{2}[/tex] ft

[tex]L=13\frac{1}{4}ft[/tex] is the length, converting into improper fraction,

[tex]L=\frac{13\cdot 4+1}{4}=\frac{53}{4}[/tex] ft

Substituting into eq (1), we can find the area of the canvas:

[tex]A=\frac{19}{2}\cdot \frac{53}{4}=\frac{1007}{8}=125.9 ft^2[/tex]
