$21.45 x 6 = $128.7
$128.7 + $10.60 = $139.3

The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
Answer:
(-8)(1) = -8
Step-by-step explanation:
The expression that uses utilizes a multiplicative inverse is (-8)(1) = -8
A multiplicative inverse is such that when an identity element such as the number 1 multiplies another, it does not change it in any way.
The expression where we see this is the option C;
(-8)(1) -8 multiplied by 1 does not change -8, it is still -8.
Hey there! I'm happy to help!
We see that the ladder reaches a height of 6m from the ground while being 2.4 m from the wall. The ratio of the height to the length from the wall is 6:2.4 which can actually just simplify to 2.5 because 6m to is 2.4*2.5.
This person is 80 cm from the ladder's base. We just saw that you can take the distance from the wall (in this case, our wall is the human as the human is touching the height) and multiply it by 2.5 to find the height of the ladder at that specific point. So let's do that.
80*2.5= 200
We are looking for meters though. Since there are 100 centimeters in a meter, this is just going to be 2 meters.
Have a wonderful day! :D
Let the line that contains the point (2,1) be x.
Slope of the line y=3x-4 is 3
Since line y=3x-4 is parallel to x, the slope of x is also 3.
