Answer:

Similar - Top center, bottom left

Not similar, different shape - Top left, bottom right

Not similar, different ratio of side lengths - Top right, bottom center

Step-by-step explanation:

We can see automatically that the top left and bottom right are not similar because they are a triangle and a trapezoid, not a rectangle.

Top right is not similar because of its different ratio of sides. The ratio for the sides of the original rectangle is 3:7, while the ratio of the top right is 2:3.5 .

Bottom center is not similar because of its different ratio of sides as well, as its ratio is 6:12

Jim’s Gym has an initial fee of $300 to join the gym and then charges $3 per visit. Sally’s Salon has an initial fee of $250 and

aksik [14]

The system of equation is y = 300 + 3x and y = 250 + 5x and the number of visits is 25

<h3>The system of equations </h3>

The given parameters are:

Jim's Gym

Initial fee = $300
Charges = $3 per visit

Sally's Salon

Initial fee = $250
Charges = $5 per visit

The equation is calculated as:

Total (y) = Initial * Charges * Number of visits (x)

So, the system of equation is

y = 300 + 3x

y = 250 + 5x

<h3>Number of visits before the plans are equal</h3>

We have:

y = 300 + 3x

y = 250 + 5x

Substitute y = 300 + 3x in y = 250 + 5x

300 + 3x = 250 + 5x

Evaluate the like terms

-2x = -50

Divide by -2

x= 25

Hence, the number of visits is 25

Can someone help me with the first 3 as it is my first time doing it ? I need help

Fed [463]

You problem is you don't have any problem. You have a bunch of formulas for the perimeter and area of some shapes.

As for using the formulas, usually you're given all but one of the variables and you can solve for the remaining one.

Notice how the triangle result doesn't have area as a function of a, b and c. That's called Heron's formula and is usually not taught to secondary school students. I don't like to teach it either because Archimedes' Theorem is so much better:

The sides a,b,c and area S of a triangle satisfy

$16S^2 = (a+b+c)(-a+b+c)(a-b+c)(a+b-c) = 4a^2b^2-(c^2-a^2-b^2)^2 = (a^2+b^2+c^2)^2 - 2(a^4+b^4+c^4)$

An airplane at 30,100 feet above the ground into sending at the rate of 2150 feet per minute. Write and solve a linear equation

Art [367]

Answer:

30,100 - 2150m = 0 m = 14

Step-by-step explanation:

First, the linear equation to find how long it will take would be 30,100 - 2150m , with m being the number of minutes it took. m = 14, because 2150 × 14 equals 30,100, and 30,100 - 30,100 equals 0.

Komok [63]

Answer:

The correct option is a) $H_0$ : m ≤ 30, $H_a$ : m > 30

Step-by-step explanation:

Consider the provided information.

A pizza shop advertises that they deliver in 30 minutes or less or it is free.

People who live in homes that are located on the opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.

$H_0$ : Pizza shop makes and delivers the pizza ≤ 30 minutes.

$H_a$ : Pizza shop makes and delivers the pizza m > 30 minutes.

Hence, the correct option is a) $H_0$ : m ≤ 30, $H_a$ : m > 30
