I really need a picture to answer this question.
Answer:
36
Step-by-step explanation:
Hey There!
So if you didn't know all of the angles in a triangle add up to equal 180
so to find the missing angle we subtract the given angles from 180
180-90-54=36
therefore the missing angles is 36
Answer:
c(12 + 9 + 6)
12(2.25c)
Step-by-step explanation:
12c + 12 (3/4c) + 12 (1/2c)
12(1c) + 12(3/4c) + 12 (1/2c)
12(c + 3/4c + 1/2c)
12(2 1/4c)
12(2.25c)
Or
12c + 12 (3/4c) + 12 (1/2c)
12c + 9c + 6c
c(12 + 9 + 6)
Answer:
The x intercept would be -4
Step-by-step explanation:
First, get your numbers into slope intercept form, y = mx + b. This would be y = -1/2x - 2. Then, replace y for 0, which would be 0 = -1/2x - 2. Add 2 on both sides to get 2 = -1/2x. then, multiply each side by -2, you end up with -4 = x, which means -4 is your x intercept.
When you're doing scientific notation you move the decimal between two numbers to make the numer between 1-9.
a)
in this case you have 12,820,000 you move the decimal between 1 and 2 so you have 1.282 then you count the number of places you've moved the decimal, which is 7, therefore your answer is 1.282×10 to the 7th power.
b)
since its 3.5 times further you multiply 12,820,000 by 3.5 and you get 44,870,000. so you don the same thing you did before you move the decimal between 4 and 4, so you get 4.487 and since you moved the decimal and since you've moved that 7 places also you get 4.487×10 to the seventh power
it's easy once you understand it but mainly you've got to move the decimal in between two numbers, which is less than 9 and greater than 1.
