A circular wire of length 176 cm is rebound to a rectangle whose length is same as the diameter of the circle. Find the difference in both the areas ?
Answer:
The difference in area is 672 cm^2
Step-by-step explanation:
Firstly, let us get the diameter of the circle
The length of the wire is the measure of the circle’s circumference
mathematically;
C = pi * d
176 = 22/7 * d
22d = 7 * 176
d = (7 * 176)/22
d = 56 cm
So, the area of the circle will be;
pi * d^2/4
= 22/7 * 56 * 56 * 1/4
= 2464 cm^2
Also, the length of the circumference is same as the perimeter of the rectangle
From the perimeter of the rectangle, we can get the width and use that to calculate the area of the rectangle
The formula for the perimeter of the rectangle is;
2(l + b)
2(56 + b) = 176
56 + b = 88
b = 88-56
b = 32 cm
So, the area of the rectangle will be;
32 * 56 = 1792 cm^2
The difference between the two areas will be;
2464-1792 = 672 cm^2

-0.45x + 0.33 = -0.66
What is the solution?
x = -2.2
x = -1.4
x = 1.4
x = 2.2
Answer:
LAST ONE: x=2.2Step-by-step explanation:
-0.45x + 0.33 = -0.66
Hope this helps
Answer:
x = 11/5 or 2.2Step-by-step explanation:
-0.45x + 0.33 = -0.66 subtract 0.33 both sides
-0.45x = -0.66 - 0.33 simplify
-0.45x = -0.99 multiply both sides by 100
-45x = -99 divide -45 both sides
x = -99 / -45 simplify
x = 11/5 or 2.2

Step-by-step explanation:
A flower shop sells 11 different bouquets and multiple different styles of vase. Which are the possible numbers for the total number of combinations of bouquet and vase?
Total combinations would be found by multiplying the number of different bouquets by the number of different vases.
The problem doesn't say how many different vases there are so using the letter v for vases, multiply 11 by v
Total combinations = 11v

please can someone help my assignment
Answer:
Find answers below
Step-by-step explanation:
First know that any value raise to power zero is 1 and also according to the inverse law;
a⁻ⁿ = 1/aⁿ
Given the following
a) (-123)⁰ = 1 ()Note that any value raise to zero is 1
b) 43⁻⁵ = 1/43⁵
1/43⁵ = 1/147,008,443
c) 1/15⁻⁶ = 1/(1/15⁶)
1/(1/15⁶) = 1*15⁶/1
1/(1/15⁶) = 15⁶
d) -(1353348)⁰
= -1 (anything raise to zero is 1)
e) 13⁻⁴ = 1/13⁴
= 1/28,561

A lent B rs 32500 to purchase a car at 12.5% p.A
Answer:
6,483.75
Step-by-step explanation:
Calculation to find the interest paid by B after 3/2 year
First step is to calculate the Compound interest amountUsing this formula
Interest paid= P(1 + r/100)^Time
Where,
P represent principal=32,500
r represent Rate of interest = 12.5%/2 = 6.25%
T represent Time=3/2 years
Let plug in the formula
Compound interest amount= 32,500(1 + 6.25/100)^2*3/2
Compound interest amount= 32,500([1+.0625)^3
Compound interest amount= 32,500(1.0625)^3
Compound interest amount= 32,500 *1.1995
Compound interest amount= 38,983.75
Now let calculate the Interest paid by B
Interest paid by B = 38,983.75 - 32,500
Interest paid by B = 6,483.75
Therefore the interest paid by B after 3/2 year will be 6,483.75
What is the length of the hypotenuse in the triangle below?
A right triangle is shown. 2 sides have lengths of 14 centimeter. The length of the hypotenuse is unknown.
Answer:
your answer will be 14 square root 2cm :)
Step-by-step explanation:
Just got done with the pretest this is correct also known as answer B!
The required length of the hypotenuse is 14√2.
The 2 sides of the right angle triangle are known i.e. 14 centimeters. Length of the hypotenuse to be determined.
The right angle triangle is defined as which contains at least one angle of 90°.
Here, other two side of hypotenuse is 14 centimeter.
Hypotenuse = [tex]\sqrt{14^2+14^2}[/tex]
= [tex]14\sqrt{2}[/tex]
Thus, the required length of the hypotenuse is 14√2.

a sales person at a jewelry store earns 3% commission each week. Last week, Heidi sold $680 worth of jewelry. How much did she mKe in commission? How much did the jewelry store make from her sales?
Heidi earned $20.4 in commission
The store made __ from her sales
Answer: $659.60
Step-by-step explanation:
Heidi commission = 3% * 680
= $20.40
The amount the Jewellery store made will be what she sold less the commission owed to her:
= 680 - 20.40
= $659.60
For each handmade greeting card Jacqui sells, she makes a profit of $0.35. In one week, she made a profit of $42. About how many greeting cards did Jacque sell that week
Answer: Jacque sold 120 greeting cards in that week.
Step-by-step explanation:
Given : Profit per card = $ 0.35
Total profit = $42
Number of greeting cards Jacque sold = (Total profit) ÷ (Profit per card)
[tex]=\$42\div\$0.35\\\\=\dfrac{4200}{35}\\\\= 120[/tex]
Hence, Jacque sold 120 greeting cards in that week.
