Answer:
i. y = 4
ii. p = 45
iii. m = 5
Step-by-step explanation:
(a) In triangle PQR, PQ = QR. So that,
Perimeter = PQ + PR + QR
40 = (2y + 3) + (5y - 2) + (2y + 3)
= 2y + 3 + 5y - 2 + 2y + 3
40 = 9y + 4
40 - 4 = 9y
36 = 9y
y = ![\frac{36}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B9%7D)
y = 4
(b) The age of Rahim's father is p years. Since he is 29 years older than Rahim, we have;
p = 16 + 29
p = 45
Rahim's father is 45 years old.
(c) Cost of a chair = RM 5.90
Cost of m chairs = RM 5.90 x m
= RM 5.90m
Amount paid = RM 50 - RM 20.50
= RM 29.50
Thus,
RM 5.90m = RM 29.50
5.90m = 29.50
m = ![\frac{29.50}{5.90}](https://tex.z-dn.net/?f=%5Cfrac%7B29.50%7D%7B5.90%7D)
= 5
m = 5
The number of units of chairs bought is 5.
The answer is 8.8
You have to use SohCahToa to figure out the length of AB
Answer:
$48,739.50
Step-by-step explanation:
You are going to want to use the simple interest formula for this.
![I = Prt](https://tex.z-dn.net/?f=I%20%3D%20Prt)
<em>P = principal amount
</em>
<em>r = interest rate (decimal form)
</em>
<em>t = time (years)</em>
<em />
First convert 4.5% into its decimal form:
4.5% ->
-> 0.045
Next, we need to change 120 months into years:
![\frac{120}{12} =10](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B12%7D%20%3D10)
<em>(10 years)</em>
<em />
Now, plug in the values into the equation:
![I=108,310(0.045)(10)](https://tex.z-dn.net/?f=I%3D108%2C310%280.045%29%2810%29)
![I=48,739.50](https://tex.z-dn.net/?f=I%3D48%2C739.50)
The interest earned after 120 months was $48,739.50
Answer:
the first answer is D.
