Divide 20 chocolates between Adi and Suresh such that adi gets 60% while Suresh gets 40% of the chocolates
Eddi Din [679]

Hello!

To find how much chocolate Adi and Suresh receives, you need to convert the percentage to a decimal, then you multiply that decimal by the total number of chocolates, which is 20.

To convert percentages to decimals, divide the percentage by 100, and remove the percentage.

60% / 100 = 0.60

20% / 100 = 0.20

Then, we multiply 0.60 and 0.20 by 20.

0.60 x 20 = 12

0.40 x 20 = 8

Therefore, Adi gets 12 chocolates and Suresh gets 8 chocolates.

Bruno noticed today’s gasoline price at the local convenience store was advertised as $3.40 per gallon. This price is 15% above
Lisa [10]

Answer:

Last year’s price = $2.96

Step-by-step explanation:

Given:

Current price of gasoline = $3.40

Higher rate = 15%

Find:

Last year’s price

Computation:

Last year’s price = Current price of gasoline [100 / (100 + 15)]

Last year’s price = Current price of gasoline [100 / (115)]

Last year’s price = $3.40 [100 / (115)]

Last year’s price = 2.95652

Last year’s price = $2.96

vekshin1

Answer:

2.75

Step-by-step explanation:

0.3,1.5,1.5,1.5,2.6,2.9,3.8,3.8,4.2,9.1

(smaller to greater)

middle of this is 2.6 and 2.9

so, 2.6+2.9=5.5

now we divide it by 2

so, 5.5/2=2.75

Find the value of x, circles and angles
lorasvet [3.4K]

Answer:

x = 50

Step-by-step explanation:

When two secants intersect in the interior of a circle, the angles formed are the average of the arc an angle and its vertical intercept. In this case, our angle, 73, should be the average of x and 96. We can translate this to an equation and solve:

\frac{x+96}{2} = 73

x + 96 = 146

x = 50
