Answer:
(B)
Step-by-step explanation:
v^2 = v0^2 + 2ax
a = (v^2 - v0^2) / 2x
= (20^2 - 10^2) / 200
= 1.5 m/s
Answer:
that number is 100
Step-by-step explanation:
Firstly, we will find place value of 9 in 392,065.018
3<u>9</u>2,065.018
We can see that
it is at 10th thousand place
so, place value of 9 is
![=10000](https://tex.z-dn.net/?f=%3D10000)
now, we are given
a number in which the value of 9 is 1/100 the value of the 9 in the number 392,065.018
so, we can get a number as
![=\frac{1}{100}\times 10000](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B100%7D%5Ctimes%2010000)
now, we can simplify it
![=100](https://tex.z-dn.net/?f=%3D100)
So, that number is 100
First you combine like terms ( that means add up, subtract, multiply, or divide it) in this case its 2x+2. 2x+2=4x. Now remember we always do the distributive property first so now we go to the next set of parenthesis. Nowwe combine -1 and 6x. Now that we have done that we have to multiply our new numbers to the number before the parenthesis. First we do 7*4x,our product is 28x. Right now our expression looks like this. 28x-5x. But were not done yet. now we subtract 28x by 5x. Our answer is 23x. Do the same process with question 8 and remember to use PEMDAS to help you.
Part A. (x + 10) is equal to (4x - 35) because they are vertical angles, so x + 10 = 4x - 35, 45 = 3x, x = 15.
Part B. Because the other two angles are also vertical, options A and B are incorrect. Because we figured out that x = 15, plugging that into both equations gets you 25 on both equations (they are equal because they are vertical angles). 2 × 25 equals 50, and because the angles of a circle add up to 360, 360 - 50 = 310. 310 ÷ 2 = 155, so the correct answer is C.
