This is as close as it can be considering that the picture is a bit blurry. It should be almost exact, but your teacher might want you to round up.
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°
Answer: 480 mL, 600 mL
Step-by-step explanation:
Given
The concentration of the first acid is 75%
The concentration of the second acid is 30%
The final mixture has a concentration of 50%
The final volume is 1080 mL
Suppose x and y be the volume of the first and second acid
Solving the above equations we get
So, the quantity of the first acid is 480 mL and 600 mL for the second mixture.
Answer:
From least to greatest, the correct order is: 
; -7.666....; -7.64; and 
.
Step-by-step explanation:
Since is the only positive number, that means that it will be the greatest number on the list. is equivalent to -7.85, which makes it the smallest number. So you can conclude that the correct order is ; -7.666...; -7.64; and .
