❖ 20% as as a fraction in lowest terms is
Percents are out of 100% so write 20% out of 100% as a fraction:
Both the numerator and denominator can be divided by 20 so once divided, you get
~ ʜᴏᴘᴇ ᴛʜɪꜱ ʜᴇʟᴘꜱ! :) ♡
~ ᴄʟᴏᴜᴛᴀɴꜱᴡᴇʀꜱ
So we will be using dimensional analysis to solve it as such:
In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.
Yes for the first two, no for the rest i think x
Answer:
$600.00
Step-by-step explanation:
15% as a decimal is 0.15
multiply 0.15 by 1000 to get the 15% of their sales
0.15×1000=150
add 150 to their weekly pay, 450
450+150=600
Answer:
y = ≈ 8.24
Step-by-step explanation:
Let's put some values of x and y into the equation to solve for a and b. We'll go with (60, 7) and (90, 4).
(60, 7): 7 = a * + b ---- by basic trig, cos(60) = 1/2, so:
7 = 0.5a + b
(90, 4): 4 = a * cos(90) + b ---- by basic trig, cos(90) = 0, so:
4 = b
We know b, so we can solve for a:
7 = 0.5a + 4
a = 6
Now, we have: y = 6cos(x) + 4
We can put 45 in for x and solve for y:
y = 6cos(45) + 4 ---- by basic trig, cos(45) =
y =
Thus, y = ≈ 8.24.
Hope this helps!
