The answer is thirty four

Answer 2

Answer:

16 + 2*pie

Step-by-step explanation:

perimeter of parallelogram : 4+8+4= 16

perimeter of a semicircle : 2*pie* r but it is semi circle so /2 radius is 4/2 which is 2 so 2*pie will give you the perimeter of your semicircle

perimeter of the shape 16 plus perimeter of the semicircle

Make the units place 0. Rounding to the tens place always gives a 0 at the units place

If you want to round to the 100s place

Round the hundreds place using the five or more or 4 or less rule from the above rules.You should have 2 zeros at the end.

If you want to round to the 1000s place

Round the thousands place using the five or more or 4 or less rule from the above rules.You should have 3 zeros at the end.

Ms. Clandestine is planning to take her study group on a field trip to an amusement park. The regular cost is $25 per person. There is a party special that costs $15 per person with an additional $150 fee for a private room where students can eat lunch. Ms. Clandestine is trying to decide if she should use the regular price or the party special.

Question 1:Write an equation to show the total cost of the regular price with x people.
Group of answer choices

y=5x + 2

y=2x + 5

y=25x

None of the above

Question 2:Write an equation to show the total cost of the party special with x people.
Group of answer choices

y=15x + 25

y=15x + 150

y=150x + 15

None of the above

Question 3: What is the solution to this system?

Group of answer choices

(-375, 15)

(-15, 375)

(375,15)

(15,375)

Question 4: What does the solution mean in relation to THIS PROBLEM?

Answers

Question 1:

Multiply the regular price by the number of people (x)

Y = 25x

Question 2:

Multiply the special rate by number of people(x) and add the cost of the room:

Y = 15x + 150

Question 3:

Replace x with a positive value and solve for y, which will be larger than the x value

Answer (15,375)

Question 4:

This means for 15 people the total cost for the special rate would be $375

x = 20

NM = 20

If f(x) = (x)(4^x), what is the simplified second derivative?

Answers

First find f’(x) using the product rule.

The product rule shows how to find the derivative of two terms being multiplied together. The formula is: f(x) = xy, f’(x) =(x)(y’)+(y)(x’)

The derivative of a^x = a^x(lna)

The derivative of x(4^x) is (x)(4^x(ln4))+(4^x)
which can be written as 4^x(ln(4)(x) +1)

To take the f’’(x), use the product rule again.
4^x(ln(4)) + (ln(4)(x) + 1)(4^xln4). You can factor out 4^x(ln(4)) to get 4^xln(4)(ln(4)(x)+1+1))

1+1=2. The final simplified answer is (4^xln(4))(ln(4)(x)+2). I don’t think you can simplify anymore

Answer:

In both cases you are really multiplying the same numbers together.

Step-by-step explanation:

30% of 40 would be 30 x 40 x 0.01 = 12

or 0.30 x 40 = 12

40% of 30 would be 40 x 30 x 0.01 = 12

EXPRESS THE AREA OF THE ENTIRE RECTANGLE. YOUR ANSWER SHOULD BE A POLYNOMIAL IN STANDARD FORM

Answers

Answer:

(x+7) times (x+3)

Step-by-step explanation:

Because a area of a rectangle is lw and you combine x and 3 to make x+3 and 7 and x to make x+7 and you multiply them together.

The area of the rectangle will be (x² + 10x + 21) unit².

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The Length of the rectangle = x + 7

And, The width of the rectangle = x + 3

Now,

Since, The Length of the rectangle = x + 7

And, The width of the rectangle = x + 3

We know that;

The area of rectangle = Length × Width

= (x + 7) × (x + 3)

= x² + 3x + 7x + 21

= x² + 10x + 21

Thus, The area of rectangle = (x² + 10x + 21) unit²

Answer:

x = 8

Step-by-step explanation:

y = 5 and 4x + 6y = 62

4x + 30 = 62

Subtract 30 from each side:

4x + 30 - 30 = 62 - 30

4x = 32

Divide each side by 4:

4x ÷ 4 = 32 ÷ 4

[tex]1260=19*83+z[/tex]

2) Simplify 19 × 83 to 1577.

[tex]1260=1577+z[/tex]

3) Subtract 1577 from both sides.

a point is chosen at random in the circle. What percent of the time will the point be in the square? Round to the nearest tenth of a percent.

Answers

Answer:

P = 0.637

Step-by-step explanation:

By a small online search, i've found that the image is a circle of radius R = 1in, and a square inside of the circle, such that the distance between the center of the square and the one vertex of the square is one inch.

To solve this problem, we need to find the area of each figure.

The area of a circle of radius R is:

A = 3.14*R^2

Then the area of our circle is:

A = 3.14*(1in)^2 = 3.14 in^2

Now for the square.

If the distance between the center and one vertex is 1 inch, then the distance between two opposite vertex is twice that: 2 inches.

Now we can think of a triangle rectangle, where both catheti are equal to L, the side length of the square, and the hypotenuse is 2 inches.

Using the Pythagoreans theorem, we get:

L^2 + L^2 = (2in)^2

2*L^2 = (2in)^2

L^2 = (2in)^2/2 = 2 in^2

L = √(2 in^2) = √2 in

And the area of a square of side length L, the area is:

A = L^2

Then the area of our square is:

A = (√2 in) = 2 in^2

Then:

Area of the circle = 3.14 in^2

Area of the square = 2 in^2

The area of the circle represents the 100% (if a point is chosen at random in the circle, the probability that the point will be inside the circle is P = 1)

The probability that the point will be inside the square is equal to the quotient between the area of the square and the area of the circle, this is:

P = (2 in^2)/(3.14 in^2) = 0.637

Step-by-step explanation:

it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16

Answer:

2 15/16

Step-by-step explanation:

We need to make sure all fractions have the same denominator.

The LCM (least common denominator) is 16.

Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.

1/2: 1x8= 8, 2x8= 16→ 8/16

3/8: 3x2= 6, 8x2= 16→ 6/16

Now every add everything all up.

8/16 + 6/16 + 2 1/16 = 2 15/16

2 15/16 is our answer.
