Answer:

5y=9x-2

y=mx-b

m=slope

y=9/5x-2/5

m=9/5=1.8 slope of pArallel

slope of pARALLEL=-1/M SLOPE OF A LINE PERPENDICULAR

m=-5/9 slope of a line perpendiculr

A square has an area of 25 cm(squared). What is the length of each side?

zloy xaker [14]

Answer:

5cm

Step-by-step explanation:

In order to find the area of a 2d regular shape such as a square, you need to do length × width = area

A square has four regular sides, which means they must all be the same length, which in turn means that we only need to find one number, and it must be the square root of 25.

5×5=25

So, the length of each side is 5cm.

Hope this helped!

3.Tracie set out from Elmhurst, IL to go to Franklin Park. On the way, she made a few stops to do errands. Each stop is indicate

fenix001 [56]

The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.

<h3>How to calculate the total distance?</h3>

The total distance is the sum of all the distance between stops.

Partial distances:

Home to stop 1: 2,000 feet
Stop 1 to 2: 4,000 feet
Stop 2 to 3: 5,000 feet
Stop 3 to 4: 4,000 feet
Total distance: 15,000 feet

However, the real distance would be 10.63 units based on the locations in the grid.

d=√(0−8)^2+(7−0)^2
d=√8^2+7^2
d=√64+49
d=√113 =10.63 units

Triangle ABC is a right triangle. If AC=12 and BC=13 find AB.

stepladder [879]

Answer:

Step-by-step explanation:

by pythagoras theorem

(hyp)^2=(leg1)^2+(leg2)^2

the hypotenuse is the side opposite to 90 degree (BC=13)

AC=leg 1 = 12

13^2=12^2 + leg 2^2

169=144+ leg 2^2

leg2 ^2=169-144

leg2^2= 25

leg2= root 25

leg2=5

the weight of an object on mars varies directly as the weight of the object on earth a 90 pound object on earth weighs 34 pounds

Mariulka [41]

We have been given that the weight of an object on the mars varies directly as the weight of the object on earth.

Let y be weight of an object on Mars and x be weight of an object on Earth.

$\\
y=kx$

We have been given that the weight of an object on Mars is 34 pounds and weight of the same object on Earth is 90 pounds.

Putting the given values in equation we get

$\\
34=k(90)\\
\\
k=\frac{34}{90}=\frac{17}{45}$

Therefore, our equation now becomes

$\\
y= \frac{17}{45}x$

Now we have been given that the weight of an object on Earth is 135 pounds and we have to find the weight of the same object on Mars,

We have been given that $\\
x=135$

Putting the given values in our equation we get

$\\
y= \frac{17}{45}(135)=\frac{17\cdot 135}{45}=17\cdot 3 = 51$

Therefore weight of the object on Mars will be 51 pounds.
