Hello!
To find this you have to divide the total number of hours studied by the time spent studying social studies
This can be done by does 4 * 0.25 = 1
The answer is 1 hour
Hope this helps!
Answer:
D
Step-by-step explanation:
3x and 30 are vertically opposite angles and congruent, then
3x = 30 ( divide both sides by 3 )
x = 10 , thus
3x = 3 × 10 = 30°
x = 10 ; angle measure is 30° → D
Ok, there is an equation you can use to solve it.
n is a number.
p is also a number, but different to n.
Therefore:

So all together there were 54 girls and 42 boys in the theatre.
54 + 42 = 96
That's 96 children in total. (Answer)
7:9 = 42:54
Let x be the length of one side of the smaller square
Let y be the length of one side of the larger square
4x would be the perimeter of the smaller square, as it has 4 sides
Therefore 4x = y + 10, as the perimeter of the smaller square is 10 inches bigger than one side of the larger square.
We're going to solve this question using simultaneous equations. This means we need another equation to compare the first one to.
Since we know that one side of the larger square is 2 inches bigger than the first one, we can make the equation
y = x + 2
Know that we know the value of y in terms of x, we can introduce this value to the original equation to find:
4x = (x + 2) + 10
Therefore:
4x = x + 12
3x = 12
x = 4
Now that we know the size of the sides on the smaller square, we can figure out the size of the larger square by using our second equation (y = x + 2)
y = 4 + 2
y = 6
Therefore, the length of each side of the larger square is<u> B.6</u>
