Answer:
The value of rate per annum is R = 12.5 %
Step-by-step explanation:
Principal amount = 576
Interest = 153
Amount after 2 years = 576 + 153 = 729
We know that
![A = P [1 + \frac{R}{100} ] ^{T}](https://tex.z-dn.net/?f=A%20%3D%20P%20%5B1%20%2B%20%5Cfrac%7BR%7D%7B100%7D%20%5D%20%5E%7BT%7D)
Put all the values in above equation
![729 = 576 [1 + \frac{R}{100} ]^{2}](https://tex.z-dn.net/?f=729%20%3D%20576%20%5B1%20%2B%20%5Cfrac%7BR%7D%7B100%7D%20%5D%5E%7B2%7D)
R = 12.5 %
This is the value of rate per annum.
Answer:
252 candies
Step-by-step explanation:
Let A = 8x
Let B = 5x
Let C = 10x
10x = 8x + 24 Subtract 8x from both sides
10x - 8x = 24 Do the subtraction
2x = 24 Divide by 2
2x/2 = 24/2 Do the division
x = 12
So Adrian has 8*12 = 96 candies.
Ben has 5 * 12 = 60 candies
Charli<u>e has 10*12 = 120 candies</u>
Total = 276 candies
Answer:
Lesser r = - 7 - √11 or -10.32 to nearest hundredth.
greater r = - 7 + √11 or -3.68 to nearest hundredth.
Step-by-step explanation:
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x + 7 = ±√11.
Answer:
14cm
Step-by-step explanation:
the area of a triangle is base x height / 2.
if you have the area and base, you can use basic algebra to get the answer.
168 = 14 x h / 2,
then you multiply both sides by 2,
2 x 168 = 14 x h,
then you divide both sides by 14 to isolate h,
<u>2 x 168</u> = h,
14
then input the values into a calculator and you should get: 14
