Answer:
4.6
Step-by-step explanation:
Use sine rule to find the number that belongs to the box.
Thus:
a = ?? (the number in the green box)
b = 5
A = 38°
B = 42°
Plug in the values
Multiply both sides by sin(38)
(nearest tenth)
Answer:
The lowest ccommon denominator (or LCD) of 1/3 and 2/5 is 15.
Step-by-step explanation:
The lowest multiple of 3 and 5 is 3*5 = 15.
In terms with the LCD, 1/3 now equals 5/15; and 2/5 now equals 6/15.
Hope this helps :)
Square root of 45 is 6.708… then the square root of 18 is 4.242… so 11?
<h2>
Answer:</h2><h2>14</h2><h2>
Step-by-step explanation:</h2>
Original Width: 10.5
Original Length: 12
Scaled Width: 3.5
Scaled Length: ?
We will be using x to find the unknown scale multiplier
<h2>
Solving for x:</h2>
3.5=10.5/x
Multiply both sides by x:
3.5•x=10.5/x•x
3.5x=10.5
Divide both sides by 3.5:
3.5x/3.5=10.5/3.5
x=3
<h2>
To find the length, we need to divide the original length by 3:</h2>
12/3=4
<h2>The area of the scaled model (Scaled Length*Scaled Width):</h2>
Scaled Width: 3.5
Scaled Length: 4
3.5•4=14
