The length of Ruben’s rectangular backyard is 10 meters more than the width. If the perimeter of the backyard is 220 meters, what is the length of the rectangular backyard?
Answers
Answer:
60
Step-by-step explanation:
given: length = 10m + width
perimeter = 220
find length of backyard
Solution
let us assume width = x
length = 10 + width
10 + x
perimeter of rectangular backyard = 2( length + width)
= 220 = 2 ( 10 + x + x )
= 220 = 2 ( 10 + 2x )
= 220 / 2 = 10 + 2x
= 110 - 10 = 2x
= 100/2 = x = 50
so, according to above solution and Q.
width = x = 50
length = 10 + width = 10 + x = 10 + 50 = 60
So the answer is 60

2 friends shared 48 pineapple equally among themselves. One of the friends sold all his pineapple each at $5.How much did he get from selling the pineapples?
Answers
Answer:
$120
Step-by-step explanation:
48 pineapples shared equally by 2 people.
48/2 = 24
Each friend got 24 pineapples.
24 × $5 = $120
Answer: $120
Answer: $120
Step-by-step explanation:
Step 1: Find how many 1 person gets (pineapples per person)
48 pineapples divided by 2 people= 48÷2= 24 pineapples each.
Step 2: Money made by 1 person
He has 24 pineapples to sell because that's how many he is supposed to receive. he sells all of them for $5 each, so the total money he makes is 5x24= $120
Checks:
120÷24= 5
the pineapples are 5 dollars each (this is correct).
Hope this helps!

The formula for the surface area of a cylinder is [tex]2\pi rh+2\pi r^{2}[/tex]. Using this, you can calculate that the cylinder's total surface area is 56[tex]\pi[/tex].

Answer:

Solving Algebraic EquationsRulesTo solve, you must isolate the variable. This means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.
If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same.
Terminology
Variable: Any letter than stands for a value than can be solved and change value. (i.e. x, y, z, a, etc.)
Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by.
If the coefficient is 1, it means [variable] * 1. 1[variable]
Q)Subtract 23 on both sides.
29 - 23 = v + 23 - 23
v = 29

Please help ASAP: Mr.Rodriguez bought a jacket at $69.50, a tie at $15.50 and a raincoat at $75.35. If he received a discount of 12 1/2% on each of these items then what was his bill?
Answers
Mr. Rodriguez's bill after receiving a discount of 12 1/2% on each item is $140.30.
To calculate Mr. Rodriguez's bill after receiving a discount of 12 1/2% on each item, we need to find the discounted price for each item and then add them together to get the total bill.
First, let's calculate the discount for each item:
Jacket: 12.5% of $69.50
Discount on jacket = 12.5/100 * $69.50 = $8.69
Tie: 12.5% of $15.50
Discount on tie = 12.5/100 * $15.50 = $1.94
Raincoat: 12.5% of $75.35
Discount on raincoat = 12.5/100 * $75.35 = $9.42
Now, subtract the discounts from the original prices to get the discounted prices for each item:
Jacket price after discount = $69.50 - $8.69 = $60.81
Tie price after discount = $15.50 - $1.94 = $13.56
Raincoat price after discount = $75.35 - $9.42 = $65.93
Finally, add the discounted prices of all items to find the total bill:
Total bill = $60.81 + $13.56 + $65.93 = $140.30

Find the interest PLEASE: $194 at 7% each year for 13 years
Answers
Answer:
Step-by-step explanation:
the answer is
$194 (start) / 100 (100%) = $1.94 (1%)
$1.94 * 7 = $13.58 (7%)
$13.58 * 13 (13 years) = $176.54
$194 (start) + $176.54 (interest) = $370.54
the interest on $194 at 7% interest rate for 13 years is approximately $176.54.
To find the interest on $194 at an annual interest rate of 7% for 13 years, we can use the formula for simple interest:
Interest = Principal * Rate * Time
Where:
Principal = $194 (initial amount)
Rate = 7% (convert to decimal: 7% = 0.07)
Time = 13 years
Now, plug in the values:
Interest = $194 * 0.07 * 13
Calculate the interest:
Interest = $194 * 0.91
Interest ≈ $176.54
So, the interest on $194 at 7% interest rate for 13 years is approximately $176.54.
