If 4% of a number is 12, find 2% of that number.
Answer:
6
Step-by-step explanation:
4% = 12
1% = 12/4
2%= 2 x (12/4) = 6
Answer:
2% of the number is 6
Step-by-step explanation:
4% of a number is 12
We want to know what 2% percent of it is.
So if we divide the number 12 by 2 we will be able to find the answer.
Note: 4%/2 = 2%(which is the percent we are looking for) Which is why if we also divide 12 by 2 which is 12/2 we will get 2% of the number.
12/2=6

way point from the wall, which is 7 m away.
Find C(t).

18. The percentage of the time, Barry reached the base is 53%.
19. The percentage of the class that passed the test is 92%.
Step-by-step explanation:
a. 5% of $788,116 = $39,405.80
b. 75% of $32 = $24
c. John's earnings = $6.25 * 14 = $87.50
Taxes = 18%; therefore, take home = 82% (100 - 18)
He will keep 82% of $87.50 = $71.75
d. Population in 1980 = 95% of 4,800 = 4,560
e. 45% of 452 = 203
f. Mrs Eversole will pay $250 * 0.07 = $17.50
g. 36% of 500 = 180
h. 80% of $350 = $280
i. Actual height = 37.8/135 * 100 = 28 ft
j. If 41% = 294, then 100% = 294/41 * 100 = 717
k. Manuel's total collection = 42/12.5% * 100% = 336
l. If 32% = 1.7 ounces, then the chalk will be 1.7/32% * 100 = 5.31 ounces.
m. If 56% = 14, then Wanda shot 14/56% * 100% = 25
n. Newmark to Briton will be 160/85% * 100 = 188 miles
o. If 80% = 24, then the number of questions = 24/80% * 100 = 30
p. Anfernee missed 36 shots = 19% (36/191 * 100)
q. 36/225 * 100 = 16%
r. The percentage of the time, Barry reached the base is 342/644 * 100 = 53%
s. 23/25 * 100 = 92%

what is 5/6 x 3 in fraction form?
Answer:
The answer is 5/2
Step-by-step explanation:
5/6 times 3
15/6=
5/2
The fraction form of (5/6)×3 after simplification is 5/2.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, (5/6)×3.
= (5/6)×(3/1).
Now in fraction multiplication, we simply multiply the numerator with the numerator and the denominator with the denominator.
= (5×3)/(6×1).
= 15/6.
= 5/2.

Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8x − 2
Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
What is the slope intercept form of a line?The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through (-1, 11) and is parallel to the line -
y = − 8x − 2.
Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.
Now, in the slope intercept form, assume that the equation of line looks like -
y = - 8x + c
Now, the line passes through the point (-1, 11), we can write -
11 = -8 x -1 + c
11 - 8 = c
c = 3
Hence, we can write the equation of the line as -
y = - 8x + 3
Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

What is the slope of the line parallel to y=2/5x-1?
I really need help with this fast please
Answer:
The slope will be 2/5.
Step-by-step explanation:
[tex]y = 2/5x -1[/tex] is written in slope-intercept form.
This formula looks like:
[tex]y=mx+b[/tex]
where:
M = Slope x = independent variableb = y-interceptSo:
[tex]2/5[/tex] is our slope[tex]x[/tex] remains our independent variable[tex]-1[/tex] is our y-intercept.1 ). For two lines to be parallel they must have the same slope.
Slope would remain 2/52 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.
. Slope would become -5/2As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.
Lets check our work!
Choose a random ordered pair. I will choose (5, 6).
Now, using point slope-form we can find out if what was said above is true!
This formula looks like:
[tex]y - y1 = m (x-x1)[/tex]
Let us substitute:
[tex]y - 6 = 2/5(x-5)[/tex]
Distribute:
[tex]y-6=2/5x-2[/tex]
Add 6 to both sides:
[tex]y= 2/5x+4[/tex]
Now using both equations I will plot them on a graph to see if they a parallel.
As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.
Based on all of the evidence, the slope will be 2/5.
