What is Two thirds of four forths-fifths of a dozen

Answer:

The answer is B

The numbers -2.23   [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have a number list:

-15/16, 0.24, -2.23, 97%, [tex]-2\frac{2}{5}[/tex], -0.95

We can write these numbers such as:

-0.9375, 0.24, -2.23, 0.97, -2.4, -0.95

Now comparing the each number with -0.94

-0.9375 > -0.94

0.24 > -0.94

-2.23 < -0.94

0.97 > -0.94

[tex]-2\frac{2}{5}[/tex] or -2.4 < -0.94

-0.95 < -0.94

Thus, the numbers -2.23   [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

The value of 'x' in the given linear equation is 4.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, 'x' is a variable, 'A' is a coefficient and 'B' is constant."

Given liner equation is:

3(x - 7) = 33

⇒ 3x - 21 = 33

⇒ 3x = 33 - 21

⇒ 3x = 12

⇒ x = 4

Therefore, the value of 'x' is 4.

Answer:

x = 7

y = 2

Step-by-step explanation:

x² - y² = 45    

(x+y) (x-y) = 45

x + y = 9   (known)

9 x  (x-y) = 45

x - y = 5

y = x-5  

x + (x - 5) = 9  (substitute)

2x = 14

x = 7

Answer:

a) The building is 150 m tall

b) h(t)=-5(t+6)(t-5)

c) The stone hits the ground at 5 seconds.

Step-by-step explanation:

Function Models

The path of a stone thrown down from a tall building is modeled by the function:

[tex]h(t)=150-5t-5t^2[/tex]

Where h is the height in meters and t is the time in seconds after the stone is thrown.

a) To find the height of the building, we set t=0 because it's the moment when the stone is thrown and has the same height as the building:

[tex]h(0)=150-5*0-5*0^2[/tex]

[tex]h(0)=150[/tex]

The building is 150 m tall

b) The function is

[tex]h(t)=150-5t-5t^2[/tex]

Factoring out -5:

[tex]h(t)=-5(-30+t+t^2)[/tex]

Rearranging:

[tex]h(t)=-5(t^2+t-30)[/tex]

To factor the polynomial in parentheses, we must find two numbers whose product is -30 and sum is 1. We can also use the quadratic formula to find the roots and factor later.

These numbers are 6 and -5, thus the function is:

[tex]h(t)=-5(t+6)(t-5)[/tex]

c) The stone hits the ground when h=0:

[tex]-5(t+6)(t-5)=0[/tex]

The equation has two solutions:

t = -6

t = 5

The only feasible solution is t = 5, thus the stone hits the ground at 5 seconds.

15 - 5x is your final answer.

Answer:

2062 employees

Step-by-step explanation:

Basically, you have an exponential function going on here. If you start with 900 employees and add 5 percent to the amount of employees (multiply by 1.005) seventeen times, you will get the equation [tex]E=900*1.05^{17}[/tex]. If we round down (because there can not be a fraction of an employee), there will be 2062 employees after 17 years.

Answer:

b i am pretty sure

Step-by-step explanation:

Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

The measurements which are necessary for determining both the speed and velocity of a moving object.

Speed=Distance/Time

To calculate speed we need to know the distance and time.

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference

Velocity=Displacement / Time

Hence  Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

Answer:

x = -4 and y = 12

Step-by-step explanation:

Since you have y = -x + 8 you can substitute this into the first equation where y was so you have 3x + 4(-x + 8) = 36.

That way, there is only one variable and it is easier to solve.

3x + 4(-x + 8) = 36

3x -4x + 32 = 36

-x +32 = 36

-x = 4

x = -4

Plugging this into the equation y = -x +8,

y = -(-4) + 8

y = 4 + 8

y = 12
