pPLSSSS4. You need to heat 7.59 g of water from 5.2 ºC to 368 K. How much heat is
needed? Give answer in Joules and calories.
_____J
_____cal
Answers
Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk

help please !! easy question i believe :))
Answers
Solution
x is an angle hence we are gonna use the formula Sin
Sin 0 = opp/hyp
0 represents theta.
Sin 0 = opp/hyp
Sin 0 = 27/33
Put 27/33 in decimal form
= 0.8181
Transpose to make 0 the subject
Sin 0 = 0.8181
0 = Sin-1 0.8181
When adding Sin from one side to another it becomes Sin inverse.
0 = Sin-1 08181
Now we find the answer
0 = Sin-1 0.8181
= 54.89 degrees
Therefore x is equal to 54.9 to the nearest tenth.

In the function f(x) = (x^2 -6x + ___) + 20, what number belongs in the blank to complete the square?
Answers
Answer:
blank = -11
Step-by-step explanation:
The given function is :
[tex]f(x) = (x^2 -6x+x)+20[/tex]
We need to find the number x such that it forms the complete square.
If x = -11, then it will becomes,
[tex]f(x) = (x^2 -6x+(-11))+20\\\\f(x)=x^2-6x+9[/tex]
We can write it as follows :
[tex]f(x)=x^2-2(1)(3x)+(3)^2[/tex] ..(1)
We know that,
[tex](a-b)^2=a^2-2ab+b^2[/tex] ...(2)
Comparing (1) and (2).
[tex]f(x)=(x-3)^2[/tex]
So, if we put the blank equals -11, then it will become the perfect square.
what is 65% of 80 ??????????????
Answers
Answer:
Step-by-step explanation:
65% of 80 is
65*80/100=52
Answer:
52
Step-by-step explanation:
Calculate percentage:
'Percentage' is obtained by multiplying 80 by 65%.
65% × 80 =
(65 ÷ 100) × 80 =
(65 × 80) ÷ 100 =
5,200 ÷ 100 =
52
Checking:
How do we check the result?
If 65% × 80 = 52 =>
Divide 52 by 80...
... And see if we get as a result: 65%.
Calculate the percent value:
52 ÷ 80 =
0.65 =
0.65 × 100/100 =
(0.65 × 100)/100 =
65/100 =
65%

-11 + 6 equals -5.
This is because there is more negative than positive, so -11 would cancel out 6 positive, leaving behind 5 negatives.

Answers
Answer:
x=55
Step-by-step explanation:
Since the two lines are parallel the two angles are same side exterior. This means their sum is 180. So to solve put them equal to 180, x+9+2x+6=180.
First, combine like terms
3x+15=180
Then, subtract 15 from both sides
3x=165
Finally, divide the entire equation by 3
x=55
