Answer:

530

Step-by-step explanation:

The formula for the perimeter is,

P = 2(l + w)

Let's input those numbers,

P = 2(166 + 99)

Add,

P = 2(265)

Multiply,

P = 530

The sum of the exterior angles of any polygon is 360 degrees. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees. its my best guess

In a regular nonagon, each exterior angle measures 40 degrees.

A regular nonagon is a polygon that has nine sides of equal length and nine interior angles of equal measure.

To determine the measure of each exterior angle for a regular nonagon, you can follow these steps. Recall that a nonagon is a polygon with nine sides. The sum of the exterior angles of any polygon is always 360 degrees.

Divide the sum of the exterior angles (360 degrees) by the number of sides in the nonagon (9) to find the measure of each exterior angle.

Calculate: 360 degrees ÷ 9 = 40 degrees.

Therefore, each exterior angle in a regular nonagon measures 40 degrees. This means that if you were to extend one side of a regular nonagon outward, the angle formed between that extended side and the adjacent side would measure 40 degrees.

Answer:

The correct option is:  32.4 km/h

Step-by-step explanation:

The fastest recorded speed of a turtle while swimming is 9 m/s.

Now,  9 m/s [tex]=\frac{(9)meters}{(1)second}[/tex]

1 kilometer= 1000 meter

So, 1 meter [tex]= \frac{1}{1000}=0.001[/tex] kilometer

and 9 meters [tex]=(9*0.001)kilometer = 0.009[/tex] kilometer

Now, 1 hour = 3600 seconds

So, 1 second [tex]=\frac{1}{3600}hour[/tex]

Thus, we will get.........

[tex]\frac{(9)meters}{(1)second}=(\frac{0.009}{\frac{1}{3600}}) kilometer/hour =(0.009*3600)=32.4 km/h[/tex]

So, the speed of the turtle will be 32.4 km/h.

(3x^2 - 2x)(x + 4)

First step would be: distributive property.

Combine like terms.

3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.

Your answer is D.

Final answer:

The first step in finding f(x) · g(x) involves multiplying the two functions together, following the distributive property, resulting in terms like 3x³ and 12x².

Explanation:

When finding f(x) · g(x), the first step would involve multiplying the two functions together. This means multiplying each term of f(x) by each term of g(x) using the distributive property.

For f(x) = 3x² - 2x and g(x) = x + 4, the first step would look like:
f(x) · g(x) = (3x² - 2x) · (x + 4) = 3x² · x + 3x² · 4 - 2x · x - 2x · 4 = 3x³ + 12x² - 2x² - 8x

So, the correct option in this case is A) 3x³ + 12x² - 2x² - 8x.

Answer:

[tex]12x + 9y \geq = 510\\ y\leq 2x\\ y \geq 25[/tex]

Step-by-step explanation:

If x represents the number of lawns and 'y' represents the number of dogs that Fabio walked then:

The amount of money raised by Fabio plus the amount of money raised by Gwen must be greater than or equal to $ 510.

[tex]12x + 9y \geq = 510[/tex]

The number of dogs that Fabio will walk is less than or equal to twice the number of yards of lawn cleared by Gwen.

[tex]y\leq 2x[/tex]

Fabio will walk at least 25 dogs

 [tex]y \geq 25[/tex]

Finally, the restrictions are:

[tex]12x + 9y \geq = 510\\ y\leq 2x\\ y \geq 25[/tex]

Answer:

Hey there! :) y = 3x - 7

Step-by-step explanation:

Our very first step should be to rewrite our question.

3x = y + 7 ; solve for y.

In order to find out what y is equal to, we must isolate y. We can do this bu subtracting 7 from both sides of the equal sign.

3x - 7 = y + 7 - 7

Simplify.

3x - 7 = y

Therefore, y is equal to 3x - 7.

The division problem meeting with the given criteria 'dividend of a/3 and a quotient of 5a2/6b' is '(a/3) ÷ (b/2a) = 5a2/6b'. This is found by using the division formula 'Dividend = Quotient x Divisor' and solving for the divisor.

The problem can be explicitly solved using the general formula for division in variables. Given the dividend is 'a/3' and the quotient is '5a2/6b', you can solve for the divisor using the formula 'Dividend = Quotient x Divisor'. Your unknown in the equation is the divisor and hence rearranging the equation we get, 'Divisor = Dividend / Quotient'. Substituting the given values, the divisor comes out to be 'Divisor = (a/3) / (5a2/6b)' which simplifies to 'b/2a'. Therefore, the division problem matching your criteria would be '(a/3) ÷ (b/2a) = 5a2/6b'.

3 3/4 is the answer i think

Answer:

Step-by-step explanation:

3 3/4 is the answer

he saves $860 per month

calculate each of his outgoings

rent = [tex]\frac{1}{4}[/tex] × $3600 = [tex]\frac{3600}{4}[/tex] = $900

food = [tex]\frac{2}{5}[/tex] × $3600 = [tex]\frac{2(3600)}{5}[/tex] = $1440

activities = [tex]\frac{1}{9}[/tex] × $3600 = [tex]\frac{3600}{9}[/tex] = $400

savings = $3600 - ( 900 + 1440 + 400 ) = $860

To add the fractions we must make the denominators = 180.

45/180 + 72/180 + 20/180 = 137/180

Expense Total = (137/180) * 3,600 = $2,740

Savings Total = (180 - 137) / 180

Savings = (43/180) * 3,600

Savings = $860

***********DOUBLE CHECK**********************

1/4=.25     2/5 = .40     1/9 = .111111

.25 + .40 + .111111   = .761111

Expenses = .761111 * 3,600 = 2,740.00

Savings = 3,600 - 2,740.00 = 860.00

Sure, to find the area of a rectangle, we simply multiply its length by its width. Here, the length of the trampoline's jumping surface is given as 10.3 feet, and the width is given as 9.2 feet.

Step 1: Write down the length and width.
Length = 10.3 feet
Width = 9.2 feet

Step 2: Multiply the length by the width.
Area = Length × Width = 10.3 feet × 9.2 feet

Perform this multiplication to get the area.

Result: The area of the jumping surface of the trampoline is 94.76 square feet.

This means that the total surface area upon which someone can jump on the trampoline is 94.76 square feet.

Alright, so the scale of meters to feet is about 3.281 feet. So you would do 10.7 times 3.281 and that equals 35.1067 and that can be rounded to 35, so the answer would be C, 35 feet. Hope that Helped :)!

To find out the number of cans Naomi needs for her recipe, you divide the total cups of kidney beans she needs (7 1/5) by the number of cups each can holds (1 4/5), which equates to four. Naomi will therefore need four cans of kidney beans to make her baked beans.

In the content loaded Naomi's recipe for baked beans, we know she needs 7 1/5 cups of kidney beans and that each can of kidney beans holds 1 4/5 cups.

To find out how many cans she needs, we'll divide the total cups needed by the amount each can holds. Remember, when dividing fractions, it's helpful to change the division into multiplication by multiplying by the reciprocal of the second fraction.

So, 7 1/5 ÷ 1 4/5 becomes 7 1/5 x 5/9 (as 5/9 is the reciprocal of 1 4/5).

That comes out to 4 when calculation is done. Therefore, Naomi will need 4 cans of kidney beans to make the recipe.
