Answer:
If you are trying to figure out the total cost, then I believe it would be 68.544$ (68.54$ rounded).
Step-by-step explanation:
This is true because,
8.8% of 63$ is 5.544
63$ + 5.544$ = 68.544$
I am not quite sure if it is all correct, but I hope this helps! :)
Answer:
a = 7
b = 7
c = 14 [Correct option is B. 14]
Step-by-step explanation:
Since the shape is a parallelogram, to solve this problem, use some of the properties of a parallelogram:
(i) Opposite sides are parallel and congruent. Being congruent means the sides are identical. In other words, they have the same length.
From the diagram, this means that sides PQ and SR are identical. i.e
=> PQ = SR
=> 6a + 10 = 8a - 4 [collect like terms and solve]
=> 14 = 2a
=> a = 7
(ii) Opposite angles are congruent. Angles PQR and PSR are identical. i.e
<PQR = <PSR = (9b + 2)°
Also,
<SPQ = <SRQ = (18b - 11)°
(iii) Consecutive angles are supplementary. The sum of any two angles that are not opposite to each other is 180°. i.e.
<SPQ + <PQR = 180°
<PQR + <QRS = 180°
<QRS + <RSP = 180°
.
.
.
Also,
<PSR + <SPQ = 180°
(9b + 2)° + (18b - 11)° = 180° [expand bracket and solve for b]
9b + 2 + 18b - 11 = 180
27b - 9 = 180
27b = 189
b = 7
Now, since a = 7 and b = 7;
c = a + b = 7 + 7 = 14
Therefore;
a = 7
b = 7
c = 14
Answer: it will take about 5 months for the cost to be the same
Step-by-step explanation:
Let x represent the number of months it will take for the gym memberships to cost the same amount.
A gym membership at A costs $10/month plus a one-time membership fee of $15. This means that the total cost for x months would be
10x + 15
At B, the memberships costs $4/month plus a one-time $40 fee. This means that the total cost for x months would be
4x + 40
For the costs to be the same,
10x + 15 = 4x + 40
10x - 4x = 40 - 15
6x = 25
x = 25/6 = 4.2
