Answer:

  -1/2x -(5 23/42)y

Step-by-step explanation:

We assume you want to simplify the expression ...

  (2 3/10)x -(5/7)y -(4 5/6)y -(2 4/5)x

__

The mixed numbers and fractions are combined in the usual way. A common denominator needs to be found for the addition or subtraction to take place.

  = x(2 3/10 -2 4/5) -y(5/7 +4 5/6)

  = x(23/10 -28/10) -y(30/42 +4 35/42)

  = x(-5/10) -y(4 65/42)

  = -1/2x -(5 23/42)y

The angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.

The terminal side of an angle is the rotated side of the initial side around a point to form an angle. This rotation can be clockwise or counter clock wise.

The angle given in the problem is,

θ=125°

The angle which is coterminal of this angle is,

θ=125°-360°

θ=-235°

Thus, the angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

7.75-4,5 = 3.25

11-7.75 = 3.25

14.25-11 =3.25

17.5-14,25 = 3.25

It’s clear that this is an arithmetic sequence with common difference of 3.25

The equation form of such sequence is  a(n) = a×n + b ,where ‘a’ is the common difference.

Then

a = 3.25

The first term a₁ = 4.5

On the other hand, a₁ = 3.25 ×(1) + b

Then

4.5 = 3.25 ×(1) + b

Then

b = 4.5 - 3.25 = 1.25

Conclusion:

a(n) = 3.25n + 1.25

Step-by-step explanation:

Answer: don’t have a calculator but if you do write this and you will get your answer 140 x 95

Step-by-step explanation:

Answer:

y = mx + b, where m is gradient and b is y-intercept

y = 3

y = 3x + b

To find b use the coordinate (3, 7) to find b

7 = 3(3) + b

b = 7 - 9

b = -2

Therefore, the equation will be:

Therefore, the equation will be:y = 3x - 2

Answer:

1/100

Step-by-step explanation:

From 1 to 10 there are 10 numbers, so the fraction would be:

# / 10

Since you are putting the cards back into the deck, the denominator will never change.

The chances of getting " 1 " are 1 / 10.

And the chances of getting " 2 " are also 1 / 10

To find the odds of getting one-after-the-other, you multiply these 2 chances.

( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )

There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

3(5)=x

Explenation:

3*5 is equal to 15

Answer:

A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.

B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:

5y-29=3y+19

Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.

C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.

The function of the exponential decay will be y = 870(0.75)ˣ. Then the value of the quantity after 10 weeks will be 49.

Consider the function:

y = a(1 ± r)ˣ

where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction.

If there is a negative sign, then there is exponential decay happening by r fraction.

A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.

Then the function is given as

y = 870(0.75)ˣ

Then the value of the quantity after 10 weeks will be

y = 870(0.75)¹⁰

y = 870 (0.0563)

y = 48.99

y ≅ 49

The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]

One of the root is given as:

[tex]x = -2 - \sqrt 6[/tex]

As a general rule, the solution to a quadratic equation is represented by:

[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

This means that the actual root of the given root is:

[tex]x = -2 \pm \sqrt 6[/tex]

Split the equation

[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]

Answer:Find the vol of the sphere:

radius of the sphere = 3 in

V = %284%2F3%29%2Api%2A3%5E3

V = 97.858

Find the vol between the sphere and cube:

216 - 97.858 = 118.142 cu/in

Step-by-step explanation:

The figure of the cube of the length of a side is given as 18.5 in. Hence, The volume of that cube will be 6331.62 cubics in.

Suppose that:

The side length of the considered cube is L units.

Then, we get:

The volume of that cube = L³ cubic units.

We have given a figure of the cube of the length of side 18.5 in.

WE need to find the volume of the cube,

The volume of that cube = L³ cubic units.

The volume of that cube = 18.5³ cubic in.
