HELPPP ITS ABOUt DILATION EXPLANATION NEEDED PLZZZ

Answer:

It is clear from the co-ordinates of the square that CD is parallel to X axis and BC is parallel to y-axis. So,X=8,y=7

so the co-ordinates of B=(8,7)

Now after dilation of factor 2, all coordinates will be multiplied by 2.

So B'=(16,14)

What is the area of this figure?

gladu [14]

Answer:

Step-by-step explanation:

A=B times H

Given: Parallelogram length = 11 cm triangle atop the parallelogram :

short leg = 7 cm : Right triangle inside the parallelogram :

long leg = 9cmArea of parallelogram =

base * heightA = 11cm * 9cmA = 99 cm²

Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²

Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²

A right triangle has a lleg of length 16 and a hypotenuse of length 25. The length of the other leg is (Rounded to the nearest t

Wittaler [7]

Answer:

19

Step-by-step explanation:

1st you will use a^2+b^2=c^2

next you plug them in so it would be a^2+16^2=25^2

next you would solve it to a^2+256=625

then you would get 369 and square root it

and your answer will be 19.2.

Jan spends part of her year as a member of a gym. She then finds a better deal at another gym, so she cancels her membership wit

valkas [14]

She spent 8 months in the 1st gym and 4 months in the 2nd gym

Step-by-step explanation:

Jan spends part of her year as a member of a gym.

She then finds a better deal at another gym so she cancels her membership with the first gym after x months
She spends the rest of the year, y months, with the second gym
The membership to the first gym costs $75 per month, while the membership for the second gym costs $45 per month
She ended up spending a total of $780 over the course of the year

We need to find how much time she spent at each gym

∵ She spent x months in the 1st gym

∵ She spent y months in the 2nd gym

∵ Her course is a year

- There are 12 months in a year

∴ x + y = 12 ⇒ (1)

∵ The membership to the first gym costs $75 per month

∵ The membership to the second gym costs $45 per month

∵ She ended up spending a total of $780 over the course

∴ 75x + 45y = 780 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -45 to eliminate y

∵ -45x - 45y = -540 ⇒ (3)

- Add equations (2) and (3)

∴ 30x = 240

- Divide both sides by 30

∴ x = 8

- Substitute the value of x in equation (1) to find y

∵ 8 + y = 12

- Subtract 8 from both sides

∴ y = 4

She spent 8 months in the 1st gym and 4 months in the 2nd gym
