On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Answers
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%

If 1/8 of my money is $80. What is 50 % of my money
Answers
Answer:
$320
Step-by-step explanation:
An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is ([tex]\frac{1}{8}[/tex]) the total amount of money, one has to multiply (80) by (8) to find the total amount of money.
(80) * (8)
= 640
Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.
(640) * (0.5)
= 320

area=m2
(round to the neerest 100)
Answers
Answer:
22.33 m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 8 m
Angle sustained (θ) = 40°
Pi (π) = 3.14
Area of small sector (A) =?
The area of the small sector can be obtained as illustrated below:
A = θ/360 × πr²
A = 40/360 × 3.14 × 8²
A = 40/360 × 3.14 × 64
A = 22.33 m²
Therefore, the area of the small sector is 22.33 m²

Answer:
1.) x=-7
2.) x= -8
3.) x=13
4.) x=2
Step-by-step explanation:
ur lucky idc
1. 4x = -28
By dividing both sides of this equation by 4, we see that x = -7.
2. x - (-6) = -2
Note that x - (-6) is equal to x + 6. To solve the equation x + 6 = -2, subtract 6 from both sides to see that x = -8.
3. -x + 4 = -9
First, subtract 4 from both sides to get that -x = -13. Then, multiply both sides by -1 to see that x = 13.
4. -3x + 7 = 1
First, subtract 7 from both sides to get that -3x = -6. Then, divide both sides by -3 to see that x = 2.
