What is area of rectangle?Area of rectangle is the product of its sides
i.e., Area of rectangle = length x breadth
What is area of circle?The area of a circle is pi times the radius squared (A = π r²).
What is circumference of circle?The circumference of a circle is defined as the linear distance around it.
( C= 2πr)
The can of red bull is in shape of cylinder.
If we open the cylinder it will have two circular surfaces( at bottom and top) and one rectangular sheet.
Like the given figure given.
The can is 6.5 inches tall and has a diameter of about 2.5 inches.
It shows that the two circle will have the diameter 2.5 inches.
d= 2.5 inch
= 0.208 ft
radius, r= [tex]\frac{d}{2}[/tex]
r= [tex]\frac{0.208}{2}[/tex]
r= 0.104 ft
To get the length of the rectangle , we have to calculate the circumference of the circle.Circumference of the circle be,
= 2πr
= 2 x 3.14 x 0.104
= 0.653 ft
The rectangular sheet will have,
length= 0.653 ft, breadth= 6.5 inches = 0.541 ft
Now, area of rectangular sheet be,= length x breadth
= 0.653 x 0.541
=[tex]0.3532 ft^{2}[/tex]
Area of 2 circle( top and bottom of can) be,= 2 x π[tex]r^{2}[/tex]
= 2 x 3.14 x 0.104 x 0.104
= 6.28 x 0.010816
= 0.0679 [tex]ft^{2}[/tex]
Total area of can be,= Area of rectangular sheet + Area of 2 circle( top and bottom of can)
= 0.3532 + 0.0679
= 0.4211 [tex]ft^{2}[/tex]
Now, we have the wall of dimensions
length= 9 ft, breadth= 20 ft
Area of wall be,= length x breadth
=9 x 20
= 180 [tex]ft^{2}[/tex]
Number of cans required to cover the whole wall be,=[tex]\frac{area \;of\; wall}{area \;of\; can}[/tex]
=[tex]\frac{180}{0.4211}[/tex]
= 427.45 cans
≈ 428 cans

find the area of this triangle, round to the nearest tenth. I will give brainliest
Answer:
108.8yd²
Step-by-step explanation:
Area of a Side Angle Side triangle : Area = 1/2 ( a × b ) × sin(c)
where a and b = the side lengths and c = the angle
Here the given side lengths are 23yds and 9.5yds and the angle given has a measure of 85° so a = 23, b = 9.5 and c = 85
Area = = 1/2 ( a × b ) × sin(c)
a = 23 , b = 9.5 and c = 85
Area = 1/2 ( 23 × 9.5 ) × sin(85)
==> multiply 23 and 9.5
Area = 1/2 ( 218.5 ) × sin(85)
==> multiply 1/2 and 218.5
Area = 109.25 × sin(85)
==> multiply sin(85) and 109.25
Area = 108.8yd²
Note: When the triangle is not a right triangle ( when there is no 90° angle ) we have to use a special formula in order to find the area. Here this is given a side an angle and a side, when given a side an angle and another side you can solve using the formula Area = 1/2 ( a × b ) × sin(c)

Answer:

Step-by-step explanation:
A tangent meets a radius at 90°Angles in a trainable sum to 180°180 - 90 - 63 = 27°Answer:
∠OAC = 27°
Step-by-step explanation:
The radius of the circle is perpendicular to the tangent line.
Therefore, ∠ACO = 90°
The interior angles of a triangle sum to 180°
⇒ ∠OAC + ∠ACO ∠ COA = 180°
⇒ ∠OAC + 90° + 63° = 180°
⇒ ∠OAC + 153° = 180°
⇒ ∠OAC = 180° - 153°
⇒ ∠OAC = 27°

Stan has made a $125.30 monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years. he would now like to draw a monthly salary from the account. determine the amount that stan can withdraw each month for 20 years, if he plans on not having anything in the account at the end of the 20 year period and no future deposits are made to the account. a. $69,242.49 b. $69,159.05 c. $333.29 d. $333.71
The annuity of the monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years is $333.71
What is annuity?An annuity is a series of payments made at equal period of time.
future value = annuity x [(1 + i)ⁿ - 1] / i
annuity = $125.30
i = 1.5% / 12 = 0.00125
n = 35 years x 12 months = 420
future value = $125.30 x [(1 + 0.00125)⁴²⁰ - 1] / 0.00125
future value = $69,156.049 ≈ $69,156.05
annuity = [i x (present value)] / [1 - (1 + i)⁻ⁿ]
i = 1.5% / 12 = 0.00125
n = 20 years x 12 months = 240
present value = $69,156.05
annuity = (0.00125 x $69,156.05) / [1 - (1 + 0.00125)⁻²⁴⁰]
annuity = $86.45 / 0.25904

Answer:
Yes it has infinity of solutions.
Step-by-step explanation:
If you plug in certain numbers it will make the statements true.
Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=−6;4x+6y=−12
Step: Solve2x+3y=−6for x:
2x+3y=−6
2x+3y+−3y=−6+−3y(Add -3y to both sides)
2x=−3y−6
2x/2 = −3y−6/2
(Divide both sides by 2)
x= −3/2y−3
Step: Substitute −3/2y−3 for x in 4x+6y=−12:

this is kinda rushed so you might want to check my answers
Step-by-step explanation:
1. find the area of the rectangle and semi circle seperately then add
4*12 = 48, (8/2)^2 *pi /2 = 8pi = 25.12
48+25.12 = 73.12
2. find the area of the triangle and semicircle then add
11*10/2 = 55, (10/2)^2 * pi / 2 = 39.25
55+39.25 = 94.25
3. split the shape into a trangle and a square
12*(2+6+2)/2 = 60, 6*6 = 36
36+60 = 96
4. split into 2 rectangles
10*3 = 30, 6*4 = 24
30+24=54
5. find area of rectangle and subtract area of semicircle
4*14 = 56, (4/2)^2 * pi /2 = 6.28
56+6.28 = 62.28
6. area of circle minus area of rectangle
(16/2)^2 * pi /2 = 100.48, 2*5 = 10,
100.48-10= 90.48

how much will be charged in prepaid interest on a $500,000 loan with an APR of 4.725% that was closed on August 26?
Answer:
$323.65
Hope this helps :D
It will charge $323.63 in prepaid interest on a $500,000 loan.
What is prepaid interest?Prepaid interest charges are charges due at closing for any daily interest that accrues on your loan between the date you close on your mortgage loan and the period covered by your first monthly mortgage payment.
Given that, a $500,000 loan with an APR of 4.725% we need to calculate the prepaid interest on it,
The prepaid interest is calculated by :-
First, you will take your annual interest rate of 4.725% and divide it by 365 to calculate your daily rate = 4.725% / 365
After you have your daily rate, multiply it by your loan amount to calculate your daily loan interest amount = 0.013% × $500,000 = $64.72
Next, you will need to multiply the number of days between your closing and first payment by your daily interest charge = $64.72 × 5 = 323.63
Hence, it will charge $323.63 in prepaid interest on a $500,000 loan.

amantha went shopping and decided to purchase a necklace for 35% off the regular price of $44. If Samantha buys the necklace today, she will save an additional 5%. Find the sale price of the necklace with both discounts. just need answer will give brainliest giving a lot of points will five star
Answer:
$27.17
Step-by-step explanation:
Regular price of necklace = $44
If a discount of 35% is applied, then the new price of the necklace will be 65% of the regular price, as 100% - 35% = 65%
⇒ 65% of $44
= 0.65 × $44
= $28.60
If a second discount of 5% is then applied, the final price of the necklace will be 95% of the sale price, as 100% - 5% = 95%
⇒ 95% of $28.60
= 0.95 × $28.60
= $27.17
Therefore:
The sale price with a 35% discount is $28.60
The sale price with an additional 5% discount is $27.17
[tex]\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}[/tex]
Given :-
The regular price of necklace = $44
Discount on necklace = 35%
Additional save from necklace = 5%
Solution :-
First we have to found the prize of necklace that Amantha had bought at 35% discount
To find this, there is a formula
[tex]new \: price = real \: price - (discount \: percentage \times real \: price) [/tex]
Now we will put our value in this formula
[tex] = 44 - ( \frac{35}{100} \times 44) \\ = 44 - ( \frac{7}{20} \times 44) \\ = 44 - ( \frac{7}{10} \times 22) \\ = 44 - \frac{154}{10} \\ = 44 - 15.4 \\ = 28.6 \:[/tex]
Now will deduct the additional discount from this price by using same formula
[tex] = 28.6 - ( \frac{5}{100} \times 28.6) \\ = 28.6 - ( \frac{1}{20} \times \frac{286}{10} ) \\ = 28.6 - ( \frac{1}{10} \times \frac{143}{10} ) \\ = 28.6 - 1.43 \\ = 27.17[/tex]
Result :-
She spend $27.17 on buying the necklace
