Answer:

Part A) The percentage increase was 6.1\%

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%

Part B) Compare the percentage increase with the inflation

6.1\%>5\%

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

Find the value of x in 4:x::x:16
AnnyKZ [126]

Given:

4:x::x:16

To find:

The value of x.

Solution:

We have,

4:x::x:16

It means, we have

4:x = x:16

It can be rewritten as

\dfrac{4}{x}=\dfrac{x}{16}

On cross multiplication, we get

4\times 16=x\times x

64=x^2

Taking square root on both sides.

\pm \sqrt{64}=x

\pm 8=x

Since ratio can be negative or positive, therefore, the value of x is either -8 or 8.

The function C(t) = 400 + 30t models the number of classrooms, C. in the town of Sirap, t years from
maks197457 [2]

Answer:

1) S(t) = C(t) × D(t)

2) S(t) = (400 + 30t)(25 + t)

Step-by-step explanation:

The function C(t) = 400 + 30t ........... (1), models the number of classrooms, C. in the town of Sirap, t years from  now.  

The function D(t) = 25 + t ......... (2) models the number of students per classroom, D, t years from now.

Then if S(t) represents the number of students in Sirap's school system t years from now, then, we can write the relation  

1) S(t) = C(t) × D(t) (Answer)

2) Hence, the formula of S(t) in terms if t is given by  

S(t) = (400 + 30t)(25 + t) (Answer)

PLEASE HELP!!!

The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.

<h3 /><h3>How to get the angle in radians?</h3>

Remember the relation:

180° = 3.14 radians.

Then:

60° = (60°/180°)*3.14 rad = 1.05 rad.

Now, for a circle of radius R, an arc defined by an angle θ has a length:

L = θ*R

Then the length of this arc is:

L = 1.05*1 unit = 1.05 units.
