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?
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

Find the interest PLEASE: $194 at 7% each year for 13 years
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.

A laundry had 32 shirts to wash. 14 were put in the washing machine. The rest were shared equally among 6 girls to wash. How many shirts did each girl wash?
Each girl washes 3 shirts. The 18 shirts are divided equally among the 6 girls
After putting 14 shirts in the washing machine, there are 32 - 14 = 18 shirts left to wash. These 18 shirts are shared equally among 6 girls. To find out how many shirts each girl washes, we divide the total number of shirts (18) by the number of girls (6):
Number of shirts washed by each girl = Total shirts / Number of girls
Number of shirts washed by each girl = 18 / 6
Number of shirts washed by each girl = 3
Each girl washes 3 shirts. The 18 shirts are divided equally among the 6 girls, so each girl washes the same number of shirts.

Raj started with angle B and constructed angle D.
The congruent triangles are solved and the measure of HI ≅ FG and the measure of DH ≅ BF
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle being constructed be ΔCBA
Let the second triangle being constructed be ΔDEL
Now , the measures of the corresponding sides of the congruent triangles will be in the same ratio
So , measure of HI ≅ measure of FG

Integer: a whole number that can be positive, negative or zero.The sum of three consecutive odd integers
Let x be the first odd integer.
As there is a difference of 2 between consecutive odd integers, the next odd integer after x will be (x + 2).
Therefore, the next odd integer after (x + 2) will be (x + 2) + 2 = (x + 4).
So "the sum of three consecutive odd integers is thirty-nine" is:
x + (x + 2) + (x + 4) = 39
To solve
⇒ x + (x + 2) + (x + 4) = 39
⇒ x + x + 2 + x + 4 = 39
⇒ 3x + 6 = 39
⇒ 3x = 33
⇒ x = 11
Therefore, the three consecutive odd numbers are 11, 13 and 15.

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?
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
