For both of them you just make them into fraction.
For #2
and then you simplify it
36. ÷12 3
-----. =. --------
120. ÷12 10
After this you want to change the fraction to a percentage.Percentage are out of 100
so you simply will multiply by 10 to the top and bottom
3. 30
----. * 10 =. -----. = 30%
10. 100
The answer is 30%
For number #3
you simply put 63 over 240
63
-----
240
21
----
80
is that answer because it can't be simplified
after that
Answer:
IJ = 5.81 ft
To the nearest tenth = 10 ft
Step-by-step explanation:
ΔHIJ is a right angle triangle.
∠J=90°
∠H=71°
JH = 2
IJ = ?
∠I = 180 - (∠J+∠H)
∠l = 180-(90+71)
∠l = 180 - 161
∠l = 19°
Tan ∠l =.JH / IJ
Tan 19 = 2/IJ
0.3443 * IJ = 2
IJ = 2/0.3443
IJ = 5.81 ft
To the nearest tenth = 10 ft
Answer:
The quantity of first mixture = x = 75 pounds
The quantity of second mixture = 175 - x = 175 - 75 = 100 pounds
Step-by-step explanation:
Total quantity of mixture = 175 pounds
Let quantity of first mixture = x
Quantity of second mixture = 175 - x
From the given information
x (0.9) + (175 - x) × 1.6 = 175 × 1.3
By solving above equation we get
0.9 x + 280 - 1.6 x = 227.5
0.7 x = 52.5
x = 75 pounds
Thus the quantity of first mixture = x = 75 pounds
The quantity of second mixture = 175 - x = 175 - 75 = 100 pounds
Answer:
see explanation
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis. Let y = 0 in the equation and solve for x
5(0) = 2x - 1, that is
0 = 2x - 1 ( add 1 to both sides )
1 = 2x ( divide both sides by 2 )
The x- intercept is ( , 0 )
The y- intercept is where the line crosses the y- axis. Let x = 0 in the equation and solve for y
5y = 2(0) - 1
5y = - 1 ( divide both sides by 5 )
y = - 
The y- intercept is (0, - )
Answer:
The answer here is 3.
Step-by-step explanation:
Since 7 of the marbles are yellow and 13 of them are green, you would first add these numbers together to find the number of marbles that are not green. After doing this you will find that 20 of the marbles aren't green. Since there are 23 marbles, and 20 of them aren't green, you would subtract these two numbers to find that the number of green marbles is three.
