Answer:

the answer will be 9.6 cm

Answer:

4x = 180

Step-by-step explanation:

angle x = angle y so we can say both angles are 'x + x' or '2x'

angle z = twice angle y (or twice angle x because they're equal) so we can say angle z = 2x

2x + 2x = 180

Answer:

Step-by-step explanation:

we have a circle inscribed in a square

Area of the square

Asquare=14*14=196

Acircle=3.14*r^2  

r=14/2=7

Acircle=3.14*7^2=153.94

A shaded=196-153.94=42.06

Answer:

Total time taken by walking, running and cycling = 22 minutes.

Step-by-step explanation:

Let the speed of walking = x

As given,

The distance of walking = 1

Now,

As [tex]Time = \frac{Distance }{Speed}[/tex]

⇒ Time traveled by walking = [tex]\frac{1}{x}[/tex]

Now,

Given that - He runs twice as fast as he walks

⇒Speed of running = 2x

Also given distance traveled by running = 1

Time traveled by running = [tex]\frac{1}{2x}[/tex]

Now,

Given that - he cycles one and a half times as  fast as he runs.

⇒Speed of cycling =  [tex]\frac{3}{2}[/tex] (2x) = 3x

Also given distance traveled by cycling = 1

Time traveled by cycling = [tex]\frac{1}{3x}[/tex]

Now,

Total time traveled = Time traveled by walking + running + cycling

                                = [tex]\frac{1}{x}[/tex] +  [tex]\frac{1}{2x}[/tex] + [tex]\frac{1}{3x}[/tex]

                                = [tex]\frac{6+3+2}{6x} = \frac{11}{6x}[/tex]

If he cycled the three mile , then total time taken = [tex]\frac{1}{3x}[/tex] + [tex]\frac{1}{3x}[/tex] + [tex]\frac{1}{3x}[/tex] = x

Given,

He takes ten minutes longer than he would do if he cycled the three miles

⇒x + 10 = [tex]\frac{11}{6} x[/tex]

⇒[tex]x - \frac{11}{6} x = -10[/tex]

⇒[tex]-\frac{5}{6}x = -10[/tex]

⇒x = [tex]\frac{60}{5}[/tex] = 12

⇒x = 12

∴ we get

Total time traveled by walking + running + cycling = [tex]\frac{11}{6} x = \frac{11}{6} (12) = 11 (2) = 22[/tex] min

Answer:

[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=x^2-13\text{ and } g(x)=5x+1[/tex]

And we want to find:

[tex]\displaystyle (fg)(-\frac{1}{5})[/tex]

This is equivalent to:

[tex]\displaystyle =f(-\frac{1}{5})g(-\frac{1}{5})[/tex]

By substitution:

[tex]\displaystyle f(-\frac{1}{5})=(-\frac{1}{5})^2-13=\frac{1}{25}-13=-\frac{324}{25}[/tex]

And:

[tex]\displaystyle g(-\frac{1}{5})=5(-\frac{1}{5})+1=-1+1=0[/tex]

Hence:

[tex]\displaystyle =(-\frac{324}{25})(0)=0[/tex]

Our final answer is:

[tex]\displaystyle (fg)(-\frac{1}{5})=0[/tex]

Answer:

$28.80 I hope that helps if not I'm sorry if it's wrong

Step-by-step explanation:

we write "dollars per cubic yard" as "dollars/yd^3" so that the units "yd^3" will cancel when multiplying by "1.2 yd^3", leaving an answer in units of dollars

24 dollars / yd^3 * 1.2 yd^3 = 28.80

the cost would be $28.80

x=1/2 (or 1)

y=3/4

The solution for the system of equations is (1, 4).

The graph is given below.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Two equations:

y = 3x + 1

y = -x + 5

The point of intersection.

3x + 1 = -x + 5

3x + x = 5 - 1

4x = 4

x = 1

And,

y = 3x + 1 = 3 + 1 = 4

or

y = -x + 5 = -1 + 5 = 4

Now,

The graph is given below.

Thus,

The solution is (1, 4).

Answer:

24

Step-by-step explanation:

Let x = the 10's digit

Let y = the units

then

10x+y = "a number"

:

A number is 4 times the sum of its digits.

10x + y = 4(x + y)

10x + y = 4x + 4y

10x - 4x = 4y - y

6x = 3y

Simply, divide by 3

2x = y

;

The units digit is two more than the tens digit.

y = x + 2

Replace y with 2x

2x = x + 2

2x - x = 2

x = 2

then

y = 4

:

24 is the number

The two digit number is equivalent to 24.

Given is that a number is 4 times the sum of its digits. The units digit is two more than the tens digit.

Let the number be {A}. Then, we can write -

A = 10x + y                             ......... (1)

also

A = 4(x + y)                            ........... (2)

The units digit is two more than the tens digit, so we can write -

y = x + 2                               .............. (3)

So, we can write -

10x + y = 4(x + y)

10x + (x + 2) = 4(x + x + 2)

11x + 2 = 8x + 8

3x = 6

x = 2

So, we can write {y} as -

y = 4

Number will be -

10 x 2 + 4

n = 24

Therefore, the number will be equivalent to 24.

Comment on the sum of exterior angles

Imagine the figure shrunk smaller and smaller until all of the angle vertices are the same point. You can see that those angles will completely fill the angular space around that central point, so they must have a sum of 360°.

2.75x+122.5

Step-by-step explanation:

Horse=x

Stork=x+70

Whale=3/4(x+70) = 0.75(x+70) = 0.75x+52.5

x+x=70+0.75x+52.5

2.75x+122.5

Answer:

2.75h + 122.5, where h = lifespan of a horse

Step-by-step explanation:

The whale's lifespan is given in terms of the stork's.

The stork's lifespan is given in terms of the horse's.

Start by assuming a variable for the lifespan of a horse.

Let h = the lifespan of horse in years.

A horse lives h years.

A stork lives 70 years longer than a horse. A stork lives h + 70 years.

A whale lives 3/4 of the lifespan of a stork. A whale lives for (3/4)(h + 70) years.

Now that you have an expression for the lifespan of each animal, the total lifespan of the three animals is the sum of the three lifespans.

total lifespan = h + h + 70 + (3/4)(h + 70

Now we simplify the right side.

total lifespan = 2h + 70 + (3/4)h + (3/4)(70)

total lifespan = 2h + 70 + 0.75h + 52.5

total lifespan = 2.75h + 122.5

Answer: 2.75h + 122.5, where h = lifespan of a horse
