Answer:

41.13

Step-by-step explanation:

The figure is basically 8+8+circumference of a circle with 8 diameter. The circumference is 2pi(4) which is 50.27, and you add 16 to that. This gives you the answer 41.13

Thanks to garden555 for pointing out my mistake.

Answer:

60m / 41.12 m

Step-by-step explanation:

side of square is 8m

hence, radius of the semicircle is 1/2 of 8

= 4m.

2semicircles = 1 circle.

perimeter of a circle = 2πr

Taking value of π as 22/7,

= 2 x 22/7 x 4

= 176/4

= 44m

OR

Taking value of π as 3.14,

= 2 x 3.14 x 4

= 25.12m

hence, perimeter of figure is,

44 + 8 + 8 = 60m

OR

25.12 + 8 + 8 = 41.12 m

Cut diameter in half to find radius

9/2 = 4.5

radius = 4.5

This is the formula for area of a circle:

pi * radius^2

pi * 4.5^2

20.25pi

Now find pi:

20.25 * pi = 63.6

Answer:

63.6 cm is the area

Answer:

63.6

Step-by-step explanation:

1. A = πr²

2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5

3. Now that we know the radius, we plug it into our formula: A = π(4.5)²

4. Simplify: A = 3.14(20.25)

5. A = 63.62

6. Rounding to the nearest tenth makes your answer 63.6

Answer:

A Responding variable.

Step-by-step explanation:

Think about it, if you had a car and there were two different ramps, one short and one was high, would the car's speed be different from the other ramp? Yes it would, and since its changing its a responding variable, because that changes as well.

(The multiply and the x are the same, so I’m just letting you know that the first x is the letter x and the second is the multiply sign.)

x x 3 + 4 (equation)

x = 6 (solution)

Step-by-step explanation:

6 x 3 + 4

22 - 4 = 18 (which takes out the four, which means what number times 3 would get 18)

6 x 3 = 18

6 x 3 + 4 = 22

Answer:

87.92

Step-by-step explanation:

(2)(3.14)=6.28

(6.28)(14)=87.92

2(pi)(r)

Before we solve the equation let's take a look at it.

f(x) = -2x + 3

See how x appears in both f(x) and as the variable in the second half of the equation?

f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.

So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."

Catching on? We need to replace x with -1 to solve for f(-1).

So here we go:

f(x) = -2x + 3

f(-1) = -2(-1) + 3

f(-1) = 2 + 3

f(-1) = 5

Voilà! We have solved for f(-1). Hope this helped.

Answer: The distance is 15 units.

Step-by-step explanation:

Let's define the bottom left corner of the left rectangle as the point (0, 0).

we know that the rectangles are of 10 by 14, then the point O will be exactly on the middle of these two quantities (because the long side is on the horizontal axis, the point O could be written as):

O (7, 5)

Point M is on the top of the rectangle, then we know that the y component will be equal to 14.

And the x component is on the middle of the rectangle (this side is the one that measures 10 units)

the middle is 5.

And we also need to add the 14 units of the other rectangle that is lying down, then the x-component of this rectangle is 14+ 5 = 19

The point M is (19, 14)

We want to find the distance between the points (7, 5) and (19, 14)

We know that the distance between points (a, b) and (c, d) is:

Distance = √( (a - c)^2 + (b - d)^2)

In this case, the distance between points O and M will be:

distance = √( (7 - 19)^2 + (5 - 14)^2) = 15

Distance between points O and M is 15 units.

Answer:

40 sweets

Step-by-step explanation:

Let june have x sweets

may has 3x/4 sweets

April has x/2 sweets

total sweets is 90

Adding all sweets =

x/2+3x/4+x = 90

9x = 360

x = 40

Therefore June has 40 Sweets

Answer:

We conclude that the  standard form of the given function is:

[tex]f(x)=-9x^2-90x-221[/tex]

Hence, option B is correct.

Step-by-step explanation:

We know that the standard form of the quadratic function is of the form

[tex]f\left(x\right)\:=\:ax^2\:+\:bx\:+\:c[/tex]

Given the function

[tex]f(x)=-9\left(x\:+\:5\right)^2\:+\:4[/tex]

as (x+5)² = x² + 10x + 25

[tex]f(x)=-9\left(x^2+10x+25\right)+4[/tex]

Expanding  -9(x² + 10x + 25) = -9x² - 90x - 225

[tex]f\left(x\right)\:=-9x^2-90x-225+4[/tex]

simplifying

[tex]f(x)=-9x^2-90x-221[/tex]

Therefore, we conclude that the  standard form of the given function is:

[tex]f(x)=-9x^2-90x-221[/tex]

Hence, option B is correct.

Answer:

It will take Michelle 80 minutes.

They're 35.20 kilometers away from their starting point.

Step-by-step explanation:

We have to find how many minutes it would take Michelle to catch up to Juanita.

We know that Michelle's movement is represented as: d = 0.44t

Juanita's movement is represented as: d = 0.3t + 11.2

To find how many minutes it would take for Michelle to catch up, we will have to solve both equations together and solve for "t", or time.

Solve:

0.44t = 0.3t + 11.2

Subtract 0.3t from both sides.

0.14t = 11.2

Divide both sides by 0.14

t = 11.2/0.14

t = 80

This means that it would take 80 minutes for Michelle to catch up.

To find how far they are, multiply 0.44 by 80.

0.44 · 80 = 35.20

This means that they're 35.20 kilometers away from their starting point.
