Answer:3x^2 each coefficient is divisible by 3 and and you can take x^2 from both of them
Answer:
n = 3.3167 moles
Step-by-step explanation:
The number of mole in water
H2O
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
Given :
Mass = 59.75g
Mm of H2O
H - 1.00784
O - 15.999
Mm
H = 2 * 1.00784 = 2.01568
O = 15.999
Mm of H2O = 15.999 + 2.01568
= 18.01468
insert the values into the formula
n = m/Mm
n = 59.75/18.01468
= 3.3167moles
Answer:
550 miles
Step-by-step explanation:
Assuming the vertex of the triangle shown is the center of the pentagon, and the line segment shown is an altitude of the triangle:
If we join the center of (the circumscribed circle and of) the pentagon to the 5 vertices, 5 isosceles triangles are formed, all congruent to the one shown in the figure. It is clear that these triangles are congruent, so to find the area of the pentagon, we find the area of one of these triangles and multiply by 5.
The base of the triangle is 22.3 in, and the height is 15.4 ins, thus the area of the pentagon is:
5(Area triangle)=5*[(22.3*15.4)/2]=<span>858.55 (square inches).
Answer: </span>858.55 (square inches).
If you would like to know how many students will be allowed to attend recess on Friday, you can calculate this using the following steps:
7/8 of 24 students = 7/8 * 24 = 7 * 3 = 21 students
Result: 21 students will be allowed to attend recess on Friday.
