30 girls and 42 boys so idk this makes no sense and I'm older than you
Mass = 100 g
Volume = 50 cm³
Density :
D = m / V
D = 100 / 50
D = 2 g/cm³
answer A
hope this helps!.
The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224.
a=$8(7)*4
a=$56*4
a=$224
Answer:
Step-by-step explanation:
Here is a diagram of a seven sided regular polygon. You use this diagram to find out how many degrees total are in the interior of a the heptagon. There are 5 such triangles which means that since each triangle has 180o the total amount of the interior angles must be 5 * 180 = 900
Since there are 7 interior angles, the answer to how large each one of them is is found by
900/7 = 129.57 which is slightly off because it is a rounded error.
In general, the size of the angles in a regular polygon
180(n - 2 ) / n
Where n is the number of degrees in each interior angle. For example for an 8 sided figure you would get
180(8 - 2) / 8 = 180 * 6/8 = 133 degrees.
Answer:
3
Step-by-step explanation:
so you set up an equation because the sides are equal
10+x=4x+1
then you solve
10=3x+1
9=3x
x=3
