The image you provided doesnt work

Step-by-step explanation:

Answer:

The answer is 8, take away 8.25 from 210 and then divide it by 23

It's C.

The value is increasing threefold relative to the previous step.

all other function values increase by a fixed amount and are therefore linear

Answer:

Ok from what your saying i would say your talking about a circle the formula to find the area of a circle is PiR^2

so the radius times radius times 3.14

Answer:

8y = -6

Step-by-step explanation:

Simply add the equations as you would numbers.

The 'x's cancel each other out. The 'y's add together as normal numbers.

9 + (-15) = -6

6/4 or 1 1/2

Step-by-step explanation:

because there is 6 black marbles and 4 white marbles

Answer:

r = 4

a8 = 114,688

Step-by-step explanation:

a1=7

a11 = 7340032

a11 = a1*r^10

7340032 = 7 * r^10

7340032 = 7r^10

r^10 = 7340032/7

r^10 = 1,048,576

Find the 10th root of both sides

10√r^10 = 10√1,048,576

r = 4

a8 = a1 * r^7

= 7 * 4^7

= 7 * 16,384

= 114,688

a8 = 114,688

Answer:

27 pi/4 or 6 3/4 pi

Step-by-step explanation:

First find the circumference

C = 2*pi*r

C = 2 * pi *9

C = 18 pi

The find the fraction of the arc

A circle is 360 degree

135/360 =3/8

Multiply the circumference by the fraction

18 pi * 3/8 =

27 pi/4

6 3/4 pi

Answer:

The value of x is 15 inch.

Step-by-step explanation:

Area, A = 81 square inch

Perimeter, P = 48 inch

let the side is y.

[tex]y^2 = 81\\\\y = 9 inch[/tex]

Let the other side is d.

P = 4 d = 48

d = 12 inch

the length x is given by

[tex]x^2 = 9^2 + 12^2\\\\x^2 =81 + 144 = 225\\\\x = 15 inch[/tex]

So, x = 15 inch.

Answer:

(3,-3)

Step-by-step explanation:

If a coordinate (x, y) is dilated by a factor k, the resulting coordinate will be (kx, ky)

Given the coordinate (1, -1), if dilated by a factor of 3, the resulting coordinate will be (3(1), 3(-1)) = (3, -3)

Hence the required coordinate will be (3,-3)

========================================================

Explanation:

Let's find the circumference

C = 2*pi*r

C = 2*pi*30

C = 60pi

This is the exact circumference in terms of pi.

In one revolution, the point on the wheel moves forward exactly 60pi cm.

In a sense, it's "speed" is 60pi cm per revolution.

----------------

Let's convert that speed to meters per minute as shown in the diagram below (I'm using the railroad tracks method to convert).

Note the color coding to see how the units cancel. The goal is to get meters on top and minutes down below. Also note how the "pi" terms cancel since we have on top and one down below.

After the canceled stuff goes away, we multiply straight across.

Divide the results: 10800/200 = 54

The linear speed is 54 meters per minute

This speed is exact because the 60pi figure is the exact circumference

This is the speed the point on the wheel moves, and we can say that the car itself also moves at a linear speed of 54 meters per minute.

Side note: 54 meters per minute = 2.013 mph approximately, which is a fairly slow walking speed.

Answer:

Maria earns 100 dollars

E=100

Step-by-step explanation:

if E=20h and they want to know how much Maria will make in 5 hours substitute the h for 5. 20 x 5 =100

E=100

Answer:

100

Step-by-step explanation:

The equation is E=20h

E is the amount she earns.

20 is the amount of money she earns per hour.

h is the amount of hours she worked.

She worked 5 hours. h represents hours so plug in 5 where h is in the equation.

E=20h

E=20(5)

E= 20×5

E=100

Answer:

[tex]V=706.5[/tex] [tex]ft^3[/tex]

Step-by-step explanation:

Since it's saying, "how much water does your neighbor need to completely fill his pool", it's asking for us to find the volume of the pool because the volume is the amount of space inside the pool which will be filled with water.

The volume formula for a cylinder: [tex]V=\pi r^2h[/tex]

In the text, since they gave the diameter and not the radius, we need to find the radius by dividing the diameter by two: [tex]\frac{15}{2}=7.5[/tex]

Now, we can start solving.

[tex]V=(3.14)(7.5^2)(4)[/tex]

[tex]V=(3.14)(56.25)(4)[/tex]

[tex]V=(3.14)(225)[/tex]

[tex]V=706.5[/tex]

Find the geometric mean of 16 and 36. Write your answer in the simplest form.

Any obvious wrong answers will be reported.

Answer:

(3, 50) and (14,303)

Step-by-step explanation:

Given the system of equations;

y=23x–19 ....1

x²–y= – 6x–23 ...2

Substitute 1 into 2;

x²–(23x-19)= – 6x–23

x²–23x+19= – 6x–23 .

x²-23x + 6x + 19 + 23  = 0

x² - 17x + 42 = 0

Factorize;

x² - 14x - 3x + 42 = 0

x(x-14)-3(x-14) = 0

(x-3)(x-14) = 0

x = 3 and 14

If x = 3

y = 23(3) - 19

y = 69-19

y = 50

If x = 14

y = 23(14) - 19

y = 322-19

y = 303

Hence the coordinate solutions are (3, 50) and (14,303)

4^2 -2×3+6=16 is your answer

Answer:

Step-by-step explanation:

P means parenthesis, of which we have none. So we move to E, which is exponents, which we do have. So we start there:

[tex]4^2-2*3+6[/tex] becomes

16 - 2 * 3 + 6. Now we have to do multiplication/division in the order we come to it in the problem. That means multiplying 2*4 first:

16 - 6 + 6. Now we do addition/subtraction in the order we come to it in the problem:

16- 6 + 6 = 10 + 6 = 16

Answer:

C

Step-by-step explanation:

Because there are only two outcomes (winning or losing) this means that

P(winning)+P(losing)=1

if we knowing that P(winning)=.37 we can write

.37+P(losing)=1

1-.37=P(losing)

.63=P(losing)

Answer: [tex]4.016\ hr[/tex]

Step-by-step explanation:

Given

Train A has speed of [tex]v_a=75\ mph[/tex]

Train B has speed of [tex]v_b=50\ mph[/tex]

If Paris and Pisa is 500 miles apart

If they meet x hours after the start

The sum of the distances traveled by Train A and B is 500 miles

[tex]\Rightarrow 75\times x+50\times x=500\\\Rightarrow 125x=500\\\Rightarrow x=4.016\ hr[/tex]

So, after [tex]4.016\ hr[/tex] they will pass each other.
