Answer:
16
Step-by-step explanation:
(75/100)*x=12
75x=12*100
75x=1200
x=1200/75
x=16
Answer:
16
Step-by-step explanation:
divide 75 by 100
multiply 12 by 100
which is 1200

A company manufactures and sells shirts. The daily profit the company makes depends on how many shirts they sell. The profit, in dollars, when the company sells x x shirts can be found using the function f ( x ) = 8 x − 40. F(x)=8x−40. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
Domain = [0, ∞).
Step-by-step explanation:
he profit, in dollars, when the company sells x shirts can be found using the function
[tex]f(x)=8x-40[/tex]
For x=0,
[tex]f(0)=8(0)-40=-40[/tex]
It means, if company sells 0 shirts, then company makes loss (because of negative sign) of $40.
For x=5,
[tex]f(5)=8(5)-40=0[/tex]
It means, if company sells 5 shirts, then company makes profit of $0 means no loss no profit.
For x=10,
[tex]f(10)=8(10)-40=40[/tex]
It means, if company sells 10 shirts, then company makes profit of $40.
Domain is the set of input values.
We know that number of shirts can not be negative, therefore the value of x is always greater than or equal to 0.
Domain = [0, ∞).
Therefore, the domain for the function is [0, ∞).
The length of an alligator in a zoo is 14 5/6 feet.The everglades national parks list the longest alligator ever reocord in florida at 17 5/12 feet. Which is the differnce in their lenghth
Answer:
The difference in the lengths of the two alligators = 3
Step-by-step explanation:
First, let us make the lengths improper fractions, then we will find the difference from there.
Alligator 1:
Length = [tex]14\frac{5}{12} = \frac{173}{12}[/tex]
To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]
Alligator 2:
Length = [tex]17\frac{5}{12} = \frac{209}{12}[/tex]
Now Let us find the difference between the lengths:
[tex]\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3[/tex]
Therefore the difference in the lengths of the two alligators = 3
Solve the equation by inserting the assigned value.

(6a - 10) = 12 – (6 - 3a), when b=11
A = ?
Answer:
a = 5.333.. or 5 1/3
Step-by-step explanation:
I am not sure what your question is but it looks like you need to solve for a.
Based on that fact:
6a - 10 = 12 - 6 + 3a you multiply -1 by each term in the parenthesis
Then it is simple algebra
6a -10 = 6+ 3a
+10 + 10 add 10 to both sides
6a = 16 + 3a
-3a -3a add -3a to both sides
3a = 16 Divide both sides by 3
a = 5.3333

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Answer:
3
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x^2+2x-5[/tex]
To evaluate the value of f(-2), substitute -2 for x. Thus:
[tex]f(-2)=3(-2)^2+2(-2)-5[/tex]
Square first:
[tex]f(-2)=3(4)+2(-2)-5[/tex]
Multiply:
[tex]f(-2)=12-4-5[/tex]
Now, subtract:
[tex]f(-2)=8-5=3[/tex]

13 If B is the midpoint of AC, and AC = 8x – 20,
find BC.
3x-1
А в
Answer:
BC = 26
Step-by-step explanation:
Given that:
B is the midpoint of AC
Then AC = AB + BC
AC = 8x - 20 and AB = 3x - 1
Then,
8x - 20 = (3x - 1) + BC
8x - 20 - (3x - 1) = BC
8x - 20 - 3x + 1 = BC
5x - 19 = BC
But AB = BC
5x - 19 = 3x - 1
5x - 3x = - 1 + 19
2x = 18
x = 9
Hence,
Since BC = AB = 3x - 1
3(9) - 1
27 - 1
= 26

The circumference of a quarter is approximately 7.54 mm. What is its diameter to the nearest tenth of a millimeter? (π = 3.14)
Answer:
2.40mmStep-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm
