If the radius is 40 ft, what is the area of the circle?

Answers

Answer:

A = pi(r)^2

A = pi(40)^2

A = 1,600pi sq. ft.

Therfore the answer is C.) 1,600 pi sq. ft.

I hope this helps you!!

Answer:

C - 1600[tex]\pi[/tex] sq. ft.

Step-by-step explanation:

Since the answer has to be in terms of pi, we can exclude that from the equation.

The formula to find the area of a circle is [tex]\pi r^2[/tex] where r is the radius. If we plug in 40 for r, we get 1600[tex]\pi[/tex].

Answers

Calculate the area of a circle.

To start solving the exercise, we obtain as data:

π = 3r = 3 ft

We apply as a formula:

A = πr², whereA = areaπ = pir = radius

We apply the formula and solve:

A = π r²A = 3× (3 ft)²A = 3 × 9 ft²A = 27 ft²

Therefore, the area of the circle is 27 ft².

Answer: 27ft²

Step-by-step explanation: Soln:

Given that,

π=3

Radius(r)=3ft.

We have,

A = π r²

A = 3* (3)²

A=3*9

A=27ft²

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?

Answers

32 - 14 = 18
18 divided by 6 = 3
THE ANSWER IS 3

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.

Answer:

[tex]\textsf{b.} \quad 3x+5y=2[/tex]

Step-by-step explanation:

Define the given points:

[tex]\textsf{let}\:(x_1,y_1)=(4,-2)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(-1,1)[/tex]

Use the slope formula to determine the slope of the line:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-(-2)}{-1-4}=\dfrac{1+2}{-1-4}=-\dfrac{3}{5}[/tex]

Use the point-slope formula to determine the equation of the line.

[tex]\implies y-y_1=m(x-x_1)[/tex]

Substitute the found slope and point (4, -2):

[tex]\implies y-(-2)=-\dfrac{3}{5}(x-4)[/tex]

[tex]\implies y+2=-\dfrac{3}{5}(x-4)[/tex]

Multiply both sides by 5:

[tex]\implies 5(y+2)=-3(x-4)[/tex]

Expand the brackets:

[tex]\implies 5y+10=-3x+12[/tex]

Add 3x to both sides:

[tex]\implies 5y+10+3x=-3x+12+3x[/tex]

[tex]\implies 3x+5y+10=12[/tex]

Subtract 10 from both sides:

[tex]\implies 3x+5y+10-10=12-10[/tex]

[tex]\implies 3x+5y=2[/tex]

Answer:

b.  x + (x + 2) + (x + 4) = 39

Step-by-step explanation:

Definitions

Integer:  a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ...Odd number: an integer that when divided by two leaves a remainder (so not a multiple of 2).  For example, 1, 3, 5, 7 are all positive odd numbers.Consecutive: following one after the other in order.

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.

To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex].

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

Total bill is $140.30

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

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

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.

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
