Answer:
a) i) Rs 8,640
ii) Rs 12,960
iii) Rs 155,520
iv) Rs 124,416
Step-by-step explanation:
Salary = Rs 21,600 per month
a) i)
Percentage of salary spent on education = 15%
⇒ 15% of 21600 = 0.15 x 21600 = 3240
Percentage of salary spent on food = 25%
⇒ 25% of 21600 = 0.25 x 21600 = 5400
Therefore, total monthly expenses = 3240 + 5400 = 8640
ii) Monthly savings = monthly salary - monthly expenses
= 21600 - 8640
= 12960
iii) 1 year savings = monthly savings x 12
= 12960 x 12
= 155520
iv) 80% of savings = 0.8 x 155520 = 124416
The volume of a right circular cylinder is 1100 cm3 and the radius of its base is 5 cm. Calculate its curved surface area.

Answer:
c
Step-by-step explanation:
t r r rt t t 4 4. 54. 54. 54 4. rr. rt t. t
Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7
Curved surface area of cylinder = 2 πr h
= 2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)
= 440 cm²
So, the curved surface area of cylinder is 440 cm²

Milo is making 1 1/2 batches of muffins for a bake sell. If each batch of muffins calls for 1 3/4,how many cups of flour will he need ?
Answer:
2 5/8
Step-by-step explanation:
Because she has one whole batch of cookies that will require 1 3/4 of flour. Since the remainder is a 1/2 batch, you would have to half the 1 3/4. Halfing 1 3/4 is 7/8. You add 1 3/4 + 7/8 and you get 2 5/8.

Answer:
the first option is correct
In a function, y varies directly with x and the constant variation is 2, then the function is y=2x. Therefore, option D is the correct answer.
What is direct variation?Mathematical relationship between two variables which can be expressed by an equation in which one variable is equal to a constant times the other.
Given that, in a function, y varies directly with x and the constant variation is 2.
y∝x
y=kx, where k is constant variation.
Here, k=2
Then, y=2x
When x=1, 2, 3, 4 and 5.
We get, y 2, 4, 6, 8 and 10
Therefore, option D is the correct answer.

The price for 3 protein bars $3.75, and the price of 3 fruit cups is $1.50. Write the equation
that represents the relationship between the number of protein bars, x, and fruit cups, y,
that you can buy with $15.50.
How many fruit cups can you buy with 4 protein bars?
Answer:
7 fruit cups
Step-by-step explanation:
$3.75/3x + $1.50y = $15.50
So, if you have 4 protein bars, the equation would read:
1.25x + 1.5y = 15.5
1.25(4) + 1.5y = 15.5
5 + 1.5y = 15.5
1.5y = 10.5
y = 7
