1/4 as a decimal is 0.25 (divide one by four). You can also multiply 1/4 by 52, but converting it into a decimal is typically easier.
"Of" typically means multiply, so multiply 52 * 0.25 to get the product 13.
For Option A., solve for 0.25 * 52, the final result should be 13.
For Option B., convert 4% into a decimal by dividing 4 over 100, you will get 0<span>.04, multiply 0.04 * 52 to get 2.08.
</span>
For Option C., divide 52 by 4, the quotient should be 13.
For Option D., 52 over 4 is another way to write 52 divided by 4, therefore, the answer, once again, is 13.
When comparing all the answers, you will notice all the answers are equal, except option B.
2.08 is not equal to 13
Therefore, your answer is <u>B. 4% of 52</u>
Answer:
x = amount of pure acid to be added = 6.67ml
Step-by-step explanation:
George wishes to increase the percent of acid in 50ml of a 15% acid solution in water to 25% acid, how much pure acid must you add?
let
x = amount of pure acid to be added
15% of 50 + x = 25% of 50 + x
(0.15 * 50) + x = 0.25(50 + x)
7.5 + x = 12.5 + 0.25x
Collect like terms
x - 0.25x = 12.5 - 7.5
0.75x = 5
x = 5/0.75
x = 6.6666666666666
Approximately,
x = 6.67
x = amount of pure acid to be added = 6.67ml
Answer:
r = -3
Step-by-step explanation:
Performing the indicated multiplication on both sides of this equation, we get:
5r - 5 = 2r - 8 - 6
Combining the r terms: 3r - 5 = - 8 - 6.
Combining the constants: 3r = 5 - 14, or 3r = -9.
Dividing both sides by 3, to isolate r, we get: r = -3

Answer:
I thought that all races were = I thought it was fine we all loved each other and that there were protests. That the black lives matter. if a police officer kills a white man bc the white man is a threat then no one cares but if a police man kills a black man bc a black man is a threat everyone protests. I thought we were = but then black people are out there saying there lives matter. They do but white lives matter too so do blue lives and green lives and purple lives.
