Answer:

  8

Step-by-step explanation:

The area of a circle with twice the radius is 4 times the area of the smaller circle. If John's hours are proportional to area, we expect it will take him 4 times as long for the larger area.

John can expect to take 8 hours cutting the grass in the larger lawn.

___

The area of a circle with radius r is ...

  A = πr²

The area of a circle with radius 2r is ...

  π(2r)² = 4πr² = 4A . . . . . 4 times the area of the smaller circle

48.984 meters

Step-by-step explanation:

The distance around a circle is called the circumference, the formula for the circumference is...

[tex]C=\pi d[/tex]

[tex]C=2\pi r[/tex]

Since we have the diameter we will be using the first one.

[tex]C=3.14*15.6[/tex]

Answer:

what are the following?

Step-by-step explanation:

Answer: $11,600

Step-by-step explanation:

$2000 * 10% = $200

y = 200x + $2,000

12 * 4 = 48

48 = x

y = 200(48) + $2,000

y = $9,600 + $2,000

y = $11,600

Answer:

Numerator 2b^2 + 2a^2

Denominator (b-a)(b+a)^2

2b / (b+a)^2 + 2a / (b-a)(b+a)

2b (b-a) + 2a (b + a) / (b-a) * (b+a)^2

2b^2 - 2ab + 2ab + 2a^2 / (b-a)(b+a)^2

2b^2 + 2a^2 / (b-a) * (b+a)^2

Answer:

$79,617.83 per person

Step-by-step explanation:

$25,000,000,000,000 / 314,000,000 = $79,617.83 per person

The amount of debt per person is $79,617.83.

The total debt is $25 trillion and the number of people in the country is 314 million.

The debt per person is:

= Total debt / population

= 25,000,000,000,000 / 314,000,000

= $79,617.83

The amount of debt per person is therefore $79,617.83.

Answer:

8.94

Step-by-step explanation:

with a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2

if you put in the values that you have, which are 8 and 4 into the equation, you get 8^2 + 4^2 = c^2

Now simplify, and you get 16 + 64 = c^2 which can then be further simplified to 80 = c^2

To get the value c all by itself, you have to square both sides. Square root of 80 becomes 8.94, and square root of c^2 becomes just a 'c'.

Therefore, you get 8.94 = c, meaning that the missing length (hypotenuse) is 8.94 units long.

Answer:

8.94

Step-by-step explanation:

First input 6x for y in the top equation

[tex]4x-18x=14[/tex]

simplify

[tex]-14x=14[/tex]

divide both sides by -14

[tex]\frac{-14x}{-14}=\frac{14}{-14}[/tex]

Answer:

hai

a triangle's sum of interior angels is equal to 180°.

so we have this equailty

y+10°+50+2y = 180

3y+60° = 180.

to solve better, im throwing 60 near 180. 60° is going to be -60 cause of it.

3y=180-60 = 3y=120

now im dividing both 3. because both can divide by 3.

3y/3 = 120/3 = y=40

Answer:

The correct answers is D

D) 360 cubic inches

Step-by-step explanation:

We know that the Area of the base of the can is given by

A = 45 inch²

Initial height of the can = 12 inches

Fraction of height cut off = 1/3

Calculate the final height after cutting off:

Find 1/3 of 12 inches:

[tex]\frac{1}{3}\cdot12=4[/tex]

Subtract the answer from 12 to get final height:

Final height = 12- 4 = 8 inches

Can is a form of cylinder, so:

Volume = (Area)(height)

[tex]V=45\cdot8\\V=360inch^3[/tex]

Step-by-step explanation:

[tex]\sqrt{5}[/tex] gives an irrational product when multuply it by [tex]0.2[/tex].

" Irrational number is defined as the set of numbers which can not be represented in [tex]\frac{x}{y} , y\neq 0[/tex] form."

According to the question,

Given multiplier [tex]= 0.2[/tex]

A. [tex]0.7[/tex]

The product of  [tex]0.7 \times 0.2 = 0.14[/tex] which is not a irrational number but a decimal number.

Option A is not the correct answer.

B. [tex]5[/tex]

The product of  [tex]5 \times 0.2 = 1[/tex] which is not a irrational number but a whole number.

Option B is not the correct answer.

C. [tex]\sqrt{5}[/tex]

The product of  

[tex]\sqrt{5} \times 0.2 \\\\= \frac{2}{10}\times \sqrt{5} \\\\= \frac{1}{5} \times \sqrt{5}\\\\=\frac{1}{\sqrt{5} }[/tex]

which is a irrational number .

Option C is the correct answer.

D. [tex]\frac{3}{4}[/tex]

The product of  

[tex]\frac{3}{4} \times 0.2\\\\= \frac{3}{4} \times\frac{2}{10}\\ \\=\frac{3}{20}[/tex]

which is not a irrational number but a fraction.

Hence, Option C is the correct answer.

Answer:

Correct option: fourth one

Step-by-step explanation:

We can see in the table that we have three variables: the gender of the lion, the number of offspring and the age in years.

From these three variables, the gender is a categorical variable, because it can only assume a finite number of values (in this case, 2 values: M or F)

The other two variables (no. of offspring and age) can theoretically assume an infinite number of values (any non-negative integer number).

So the correct option is the fourth one: three variables, and one of them is categorical.

 I’m probably wrong but I Think its isometric.

Answer:

is this a question?

Step-by-step explanation:

2. 3x - 5y = -2

   x + 3y = 4

   Let us multiply equation 2 by three, so we can use the elimination method.

   3x + 9y = 12

   Now, let us subtract equation 1 from equation 2.

   3x + 9y - 3x + 5y = 12 + 2

   14y = 14

   y = 1

   Let us substitute this value of y in equation 2.

   x + 3(1) = 4

   x = 4 - 3

   x = 1

3. -3x + 3y = -6

   6x + 4y = 42

   Let us multiply equation 1 by 2, so we can use the elimination method.

   -6x + 6y = -12

   Let us now add equations 1 and 2, so as to eliminate x.

   6x + 4y -6x + 6y = 42 - 12

   10y = 30

   y = 3

   Let us now substitute this value of y in equation 1, so as to find x.

   -3x + 3(3) = -6

   -3x + 9 = -6

   -3x = -15

   3x = 15

   x = 5

4. 12x + 4y = 20

   2x - 2y = -2

   Let us multiply equation 2 by 2, so as to use the elimination method.

   4x - 4y = -4

   Let us now add equations 1 and 2, so as to eliminate y.

   4x - 4y + 12x + 4y = -2 + 20

   16x = 18

   x = [tex]\frac{18}{16}[/tex] = [tex]\frac{9}{8}[/tex] = 1.125

   Let us substitute this value of x in equation 2, so as to find y.

   2(9/8) -2y = -2

   9/4 - 2y = -2

   -2y = -2 - 9/4

   2y = 17/4

   y = [tex]\frac{17}{8}[/tex] = 2.125

Answer:

Option C.

Step-by-step explanation:

It is given that the surface area of a rectangular prism, is

[tex]SA=2(ab+ac+bc)[/tex]

where a, b, and c represent the lengths of the edges of the prism.  

We need to find the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches.

Substitute a=12, b=6 and c=4 in the above formula.

[tex]SA=2((12)(6)+(12)(4)+(6)(4))[/tex]

[tex]SA=2(72+48+24)[/tex]

[tex]SA=2(144)[/tex]

[tex]SA=288[/tex]

The surface area of this prism is 288 sq.inches.

Therefore, the correct option is C.

acute

Step-by-step explanation:

every angle is under 90 degrees

Answer:

The triangle is acute.

Step-by-step explanation:

-According the to following triangle, the angles are acute, because acute angles less wider and they measure less than 90°.

-The reason why the triangle is not a right or obtuse, is because right angles are angles that measure exactly 90°, and obtuse angles are angles that are much wider and they measure greater than 90°.
