Answer: a) Equation y= 20+ 1.50n.</h3><h3>b) Melia have $644 to spend on her 18th birthday.</h3>
Step-by-step explanation: We are given that Melia put $20 initially in piggy bank.
Each week amount added in piggy bank = $1.50.
Let us assume total number of weeks be n Melia added amount in piggy bank and get y amount after n weeks.
a) Therefore, total amount after n weeks = Initial amount + 1.50 times n weeks.
y= 20+ 1.50n.
b) On 18th birthday, there would be total 8 years after 10th birthday.
And in 8 years there would be 52 × 8 = 416 weeks.
So, in order to find the total amount after 8 years or 416 weeks, we need to plug n= 416 in the equation we got in a part.
Therefore,
y = 20+ 1.50(416)
y = 20 + 624 = 644.
<h3>Therefore, Melia have $644 to spend on her 18th birthday.</h3>
Answer: B = 18 degrees
C = 48 degrees
Step-by-step explanation:
Complimentary angles are angles whose sum is 90 degrees.
Angle A, angle B, and angle C are complementary angles. This means that
A + B + C = 90- - - - - - - - - - - - -1
The measure of angle C is twice the measure of angle A. If the measure of angle A is 24 degrees, it means that the measure of angle C would be 2 × 24 = 48 degrees.
Substituting A = 24 and C = 48 into equation 1, it becomes
24 + B + 48 = 90
72 + B = 90
B = 90 - 72
B = 18 degrees
