If r = 12, what is the value of t?

2 answers:

6 0

Just replace all variables that r with the variable r equivalent.

So, the expression 9 + r * 3 becomes 9 + 12 * 3

Use the order of operations to solve.

9 + 12 * 3
9 + 36 <--- The order of operations says that multiplication and division
have a higher precedence than addition and subtraction.
45 <--- Simply add.

So, the answer is 45.

Due to pemdas you would have to start with multiplication. 3×12= 36. Then you do addition which would be 9+36= 45.

Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

ivanzaharov [21]

We know that

[length of a circle]=2*pi*r
r=12 in
[length of a circle]=2*pi*12--------------> 24pi in

if 360° (full circle)--------------------> has a length of 24pi in
X-------------------------------------------> 8pi

X=8pi*360/24pi-----------> 120°

the answer is 120°

Nataly [62]

Answer:

A) The amount of change held by a teacher at the end of each day for a year.

Step-by-step explanation:

A normal distribution has a bell-shaped density curve described by its mean and standard deviation.

A) The amount of change held by a teacher at the end of each day for a year - This is probably near normal because the teacher cannot have negative cents in her or his pocket.
