Answer:
Step-by-step explanation:
so they used a total of 560 units
we are next told that if the units of usage are 360 or less use the 1st formula, but there is morn than 360 units in the given amount so use the 2nd formula
0.1(x-360+54)
0.1(560-360) + 54 = monthly bill
20+54 = monthly bill
74 = monthly bill
answer D looks good
1) Using your compass, draw a circle and label the center O.
2) Using your straightedge, draw a diameter of the circle, labeling the endpoints A and B.
3) Construct the perpendicular bisector of the diameter.
4) Label the points where the bisector intersects the circle as C and D.
Answer:
∠1=54°
∠2=54°
∠3 = 126°
Step-by-step explanation:
We need to find ∠1, 2 and 3
Since a traversal cut parallel lines we would use supplementary angles , congruent angles rules to solve the problem.
Angle 1 and 126 are supplementary angles.
They add up to make 180
So, ∠1 + 126 = 180
∠1 = 180-126
∠1 =54
We get ∠1=54°
Now, ∠1 ≅ ∠2, because they are corresponding angles and if traversal cut parallel lines, corresponding angles are congruent.
So ∠1 ≅ ∠2 therefore, ∠2=54°
Now, for finding measure for ∠3, we know that 126 and ∠4 are corresponding angles and corresponding angles are congruent.
So, ∠4 = 126°
We know that ∠3 and ∠4 are vertical angles.
And if traversal cut parallel lines, vertical angles angles are congruent.
So, ∠3 = 126°
Answer:
Option 3,4,5 are correct.
Step-by-step explanation:
The system of equations are:
Multiply equation (2) with -3 and add with equation (1)
Value of y is 3
Putting value of y in eq(2)
Value of x is -2
So, Option 3,4,5 are correct.
