A isn’t correct because there is 2 O’s on the left side and 3 on the right
B is incorrect because there is an S on the right but not on the left
C is incorrect because there are 2 Ca on the left side and 1 on the right
D is balanced as there are 2Na ok each side, 2Cl on each side,2H, and 1 SO4 on each side
Answer:
Area of geometric figures mentioned calculated.
Step-by-step explanation:
Square Perimeter = 4 x sides of square = 20. So, each equal side of square = 20 / 4 = 5
Area of square = ( Side )^2 = ( 5 )^2 = 25
Area of triangle = 1/2 (Base) (Height) = 1/2 x 3 x 3.5 = 5.25
Answer:
choice A because
2^(8.24) = 2^(8 + 0.2 + 0.04) = (2^8) *(2^ (2/10)) * (2^ (4/100))
Step-by-step explanation:
we have the power: 2^(8.24) = 2^(8 + 0.2 + 0.04)
notice.
2^(8 + 0.2 + 0.04)= (2^8) * (2^0.2) * (2^0.04)
2^(8 + 0.2 + 0.04) = (2^8) *(2^ (2/10)) * (2^ (4/100))
Answer:
To find the measure of angle OPQ, we have two equations...
y+5x-17=180 because angles OPN and OPQ are supplementary...
AND
x+17+2x-4+y=180 because the total degrees of a triangle must add up to 180.
The equations...
5x+y=197
3x+y=167
solce the system of equations...
x=15
y=122
Since we wanted to solve for y, 122 is the answer.
The measure of angle OPQ is 122.
We are given the angle measure, measure of hypotenuse and we are to find the base(Adjacent) side of the angle.
Cosine relates all these three as:
Rounded to nearest hundredth, the measure of side adjacent to the angle is 1.88
