60. You just multiply them :)
Suppose Julia made x dollars in 2015, and Anna made y dollars.
in 2016, Julia made (x+30,000) and Anna made (y+10,000)
In 2016, after they paid 50% tax, they still had 80,000, which means before tax they had a total of 160,000, so
(x+30,000)+(y+10,000)=160,000
simplify: x+y=120,000
in 2015, Julia earned 20,000 more than Anna, so x=y+20,000. Plug it in the above equation: y+20,000+y=120,000
y=50,000
x=y+20,000=70,000
Julia made 70,000 dollars in 2015.
Answer:
12 cups of water
Step-by-step explanation:
This question has to do with conversion
We are told that she buy 1 quart and 1/2 gallon of water.
Hence,
1 quart of water = 4 cups of water
1 gallon of water = 16 cups of water
1/2 gallon of water = x
Cross Multiple
x = 1/2 × 16 cups of water
x = 8 cups of water.
Therefore, the total cups of water that she bought = 4 cups of water + 8 cups of water = 12 cups of water
For a right triangle, the sine of an angle is the ratio of the length of the side opposite to it and the hypotenuse and the its cosine is the ratio between the side adjacent to it and the hypotenuse. From the given choices, the angle being referred to is letter B. 45°.
The height is 20 so plug in the area equation and your answer is 150 units squared
