Answer:
a) 55°
b) 125°
c) 55°
d) 55°
Step-by-step explanation:
a) 180-(90+35) = 55
b) this angle forms a straight angle with ∡a
c) this angle is vertical, and congruent, with ∡a
d) 180-(70+55) = 55
First we need to know the meaning of a rational number. A rational number is any number that terminates and doesn't repeat as a decimal, and can be represented as a fraction.
I would say it's 3/6, 4/6, and 5/6, you can also have 2/6 since they can be expressed as a ratio and are between 1/3 and 5/6. (1/3 is equal to 2/6)
6+0.3=6.3+0.02=6.32
6+0.02=6.02+0.02=6.04
that is correct because the answer is 6.32>6.04
Answer:
![6[\frac{5}{6}x+\frac{2}{3}]=-9*6](https://tex.z-dn.net/?f=6%5B%5Cfrac%7B5%7D%7B6%7Dx%2B%5Cfrac%7B2%7D%7B3%7D%5D%3D-9%2A6)


Step-by-step explanation:
we have

Solve for x
Multiply by 6 both sides to remove the fractions
![6[\frac{5}{6}x+\frac{2}{3}]=-9*6](https://tex.z-dn.net/?f=6%5B%5Cfrac%7B5%7D%7B6%7Dx%2B%5Cfrac%7B2%7D%7B3%7D%5D%3D-9%2A6)

Subtract 4 both sides


Divide by 5 both sides


We can use fraction to solve this problem. Since Jean can fill the pool in 8 hours and Mark in 12 hours, we can use the formula X/8 + X/12 = 1 where X/8 stands for Jean's job and X/12 for Mark's.
X - total number of hours Jean and Mark can fill the pool
To add the two fractions, we need to have the same denominator which is 24.
The equation will be (3X + 2x) / 24 = 1, which will give us a simplified formula of 5X / 24 = 1.
To get X, we need to multiply 24 to both sides (5X/24 and 1) so that the equation will be 5X = 24. We only need to solve for X, so we will remove 5 from X by dividing it to 24, giving us the equation 5X/5 = 24/5.
The final answer will be X = 24/5 hours or 4.8 hours.
Therefore, the supervisor is incorrect since Jean and Mark can fill the pool in less than 10 hours.
