how to write 2.31818 as a mixed fraction
Answer:
[tex]2\frac{15909}{5000}[/tex]
Step-by-step explanation:
To make [tex]2.31818[/tex] into a fraction, you must first move it to the numerator and make 1 the denominator.
[tex]\frac{2.31818}{1}[/tex]
And then you multiply it by [tex]10,000[/tex] or you can say [tex]10^5[/tex]
[tex]\frac{2.31818}{1}*\frac{100000}{100000}[/tex]
After you multiply you divide the numerator and denominator by 2.
[tex]\frac{231818/2}{100000/2}[/tex]
And now this equals:
[tex]2\frac{15909}{5000}[/tex]
Hope this helps!
The number before the decimals always represents the whole number of a mixed number and the number after the decimals represents the fraction part of the mixed number.
2.31818 = 2.0 + 0.31818
In 2.31818
2 represents the whole number and
0.31818 represents the fraction 31818/100000
Dividing the fraction 31818/100000 by 2 gives
15909/50000 which cannot be further reduced.
2.31818 = 2 [tex]\frac{15909}{50000}[/tex]

How do you do this question?
Answer:
-30√(t/a) cos(√(at)) + 30/a sin(√(at)) + C
Step-by-step explanation:
∫ 15 sin(√(at)) dt
Use substitution:
If x = √(at), then:
dx = ½ (at)^-½ (a dt)
dx = a / (2√(at)) dt
dx = a/(2x) dt
dt = (2/a) x dx
Plugging in:
∫ 15 sin x (2/a) x dx
30/a ∫ x sin x dx
Integrate by parts:
If u = x, then du = dx.
If dv = sin x dx, then v = -cos x.
∫ u dv = uv − ∫ v du
= 30/a (-x cos x − ∫ -cos x dx)
= 30/a (-x cos x + ∫ cos x dx)
= 30/a (-x cos x + sin x + C)
Substitute back:
30/a (-√(at) cos(√(at)) + sin(√(at)) + C)
-30√(t/a) cos(√(at)) + 30/a sin(√(at)) + C

Evaluate A² for A = -3
Answer:
9
Step-by-step explanation:
If A = - 3, than A^2 is equal to (-3)^2
If a number is squared (to power of 2), it is multiplied by itself (there are two of that number being multiplied together) so it is - 3x-3
-3 x - 3 = 9,
Because 3x3 =9 and a negative multiplied by a negative makes a positive.
Hope this helped!
Answer:
9
Step-by-step explanation:
(A)^2 is a better way to write it. That way the answer is unambiguous (-3)^2 = -3 * - 3 = 9

If uw =6x-35, find uw
Answer:
The value of uw is 67
Step-by-step explanation:
Given that,
If uw= 6x-35...(I)
Line segment consists of points u,v,w
u to v is 19
v to w is 4x-20
We need to calculate the value of x
Using given data
[tex]uw=6x-35[/tex]
[tex]uv+vw=6x-35[/tex]
Put the value of u and w
[tex]19+4x-20=6x-35[/tex]
[tex]19+35-20=6x-4x[/tex]
[tex]34=2x[/tex]
[tex]x=\dfrac{34}{2}[/tex]
[tex]x=17[/tex]
We need to calculate the value of uw
Put the value of x in equation (I)
[tex]uw=6\times17-35[/tex]
[tex]uw=67[/tex]
Hence, The value of uw is 67
What is the empirical formula of an oxide of chromium that is 48 percent oxygen by mass?
Answer:
CrO₃.
Step-by-step explanation:
We'll begin by calculating the percentage of chromium in the oxide. This can be obtained as follow:
Oxygen (O) = 48%
Chromium (Cr) =?
Oxide of chromium contains only chromium and oxygen. Therefore, the percentage of chromium in the oxide is given by:
Cr = 100 – percentage of oxygen
Cr = 100 – 48
Cr = 52%
Finally, we shall determine the empirical formula of the oxide as follow:
Chromium (Cr) = 52%
Oxygen (O) = 48%
Divide by their molar mass
Cr = 52/52 = 1
O = 48/16 = 3
Divide by the smallest
Cr = 1/1 = 1
O = 3/1 = 3
Therefore, the empirical formula of the oxide is CrO₃.
Write an equation in slope-intercept form (y = mx + b).
Parallel to 3x + 5y = 18 passing through (-10, -4).
Answer:
y= [tex]\frac{-3}{5}x -2[/tex]
Step-by-step explanation:
find the gradient by rearranging the equation, y= [tex]\frac{-3}{5}x[/tex] +[tex]\frac{18}{5}[/tex]
from here we can see that the slope or gradient is [tex]\frac{-3}{5}x[/tex]
now using the equation y-y2 = f'(x1)(x-1) we find the equation by subbing
= y- (-4) = [tex]\frac{-3}{5}[/tex] (x - [-10])
= y + 4 = [tex]\frac{-3}{5}x -6[/tex]
= y= [tex]\frac{-3}{5}x -2[/tex]

Mr. Lowe is setting up his room for art class. He has 6 boxes of crayons with 24 crayons each, 3 packages of pencils with 20 pencils each, and 9 packages of paint brushes with 15 brushes each. What is the difference between the total number of crayons and the total number of paint brushes?
so first we need to find the total number of crayons
to do that we're going to multiply 6 by 24 cause each box has 24 crayons
24 × 6 = 144
so the answer of total number of crayons is 144 crayons
next we're going to find the total number of paint brushes
to do that we're going to multiply 9 by 15 cause each package has 15 paint brushes
9 × 15 = 135
so the answer of total number of paint brushes is 135 crayons
finally we're going to calculate the difference
so its 144 crayons subtracted by 135 paint brushes
144 - 135 = 9
so the difference of total number of crayons and total number of paint brushes is 9
hope that helped :))

125 feet in 25 seconds what’s the unit rate?
Answer:
The unit rate is 5 ft/1 second
Step-by-step explanation:
Unit rates must always be a fraction with a denominator of 1
Our unit rate is 125/25
To get to a denominator of 1 divide 25 by 25
25 ÷ 25 = 1 second
What we do to one side we have to do to the other so also divide 125 by 25
125 ÷ 25 = 5 ft
frank liked to buy packs of baseball cards. on 3 different days, he bought 3 packs. on 3 other days, he bought 4 packs each day. After that he splits his packs with his 2 brothers. How many packs will they each have. Choose the expression that best matches this situation.
Answer:
First, frank buys 3 packs on 3 different days, so in those first 3 days he buys:
3*3 = 9 packs.
Then on other 3 days he buys 4 packs each day, so he has:
3*4 = 12 packs.
In total he haves:
9 + 12 = 21 packs.
Now he divides the packs with his 2 brothers (So we divide 21 packs between 3 people)
Then each brother gets:
N = 21/3 = 7 packs each.
Which of the following represents “ 10 times the sum of a number and 14 is equal 9 times the number”?
Answer:
The expressión is:
10(a+14) = 9a
and the number is:
-140
Step-by-step explanation:
The expression is:
10(a+14) = 9a
then:
10*a + 10*14 = 9a
10a + 140 = 9a
10a - 9a = -140
a = -140
Check:
10(-140+14) = 9*140
10*-126 = 1260
