The amount of white paint used by Tamara to paint the bedroom walls is 2.125.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Total amount of paint = 8.5
Three fourths of this amount is blue paint.
Amount of blue paint = (3/4) × 8.5 = 6.375
Rest is white paint.
Amount of white paint = Total paint - Amount of blue paint
= 8.5 - 6.375
= 2.125
Hence the amount of white paint used to paint bedroom walls is 2.125.

Find (f/g)(x). f(x)=/x^2-1 g(x)=/x-1
Answer:
[tex](\frac{f}{g})(x) = \sqrt{x + 1}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = \sqrt{x^2 - 1[/tex]
[tex]g(x) =\sqrt{x - 1[/tex]
Required
Find [tex](\frac{f}{g})(x)[/tex]
[tex](\frac{f}{g})(x)[/tex] is calculated as:
[tex](\frac{f}{g})(x) = \frac{f(x)}{g(x)}[/tex]
This gives:
[tex](\frac{f}{g})(x) = \frac{\sqrt{x^2 - 1}}{\sqrt{x - 1}}[/tex]
Apply difference of two squares on the numerator
[tex](\frac{f}{g})(x) = \frac{\sqrt{x - 1}*\sqrt{x + 1}}{\sqrt{x - 1}}[/tex]
[tex](\frac{f}{g})(x) = \sqrt{x + 1}[/tex]

What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?
9514 1404 393
Answer:
x in {-6, -2, 4}
Step-by-step explanation:
The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.
x +6 = 0 ⇒ x = -6
x -4 = 0 ⇒ x = 4
x +2 = 0 ⇒ x = -2
The zeros of the function are the x-values -6, -2, and 4.
i am a 5 digit number,my ones place digit is of no use as i, i still remain same without it . my ten's and hundreds place digits are mirror images. my thousand place digit are half of 2nd, my 10thousand digit is 3 more than my ones place , who am i ?
Answer:
The 5 digit number is 34880
Step-by-step explanation:
Let the five digit number be represented by "abcde".
We are told that 1 place digit number is of no use and the 5 digit number will remain the same without it.
This means that e = 0
The tens and hundreds digit are d and c respectively. We are told that they are mirror images of each other.
Thus, d = c = 8. Since 8 is the only number from 1 to 10 that can be mirrored and still remain a usable number.
The thousand digit is Half of the second digit.
Thus, b = ½d
b = 8/2
b = 4
We are told the 10thousand digit is 3 more than my ones place. Thus;
a = e + 3
a = 0 + 3
a = 3
We have seen that;
a = 3
b = 4
c = 8
d = 8
e = 0
Thus,the 5 digit number is 34880

A 200-foot cable weighing 800 pounds is hanging from a winch 200 feet above ground level.
(a) How much per foot does this cable weigh? if a piece of this cable is A.x long, what is the weigh of this piece?
(b) Find the work (in ft-lb) done in winding up the cable when there is a 400- pound load attached to the end of the cable.
Answer:
4 pd / ft
140000 ft/pd
Step-by-step explanation:
Total Weight of cable = 800 pounds
Length of cable = 200 feets
Weight per foot = Total weight / length = 800 / 200 = 4 pounds per foot
Weight of piece will be :
Weight of cable - weight per foot * x
800 - 4x
Workdone with 300 pound load attached :
∫f(x)
f(x) = (800+300 - 4x) = 1100 - 4x
∫1100 - 4xdx at 200 to 0
Integrating the above
1100x - 4/2x² at x = 200 to 0
1100x - 2x²
1100(200) - 2(200²) - 1100(0) + 2(0^²))
(220000-80000) - 0 + 0
140000 ft/pd
The vertices of ABC are A(-3,5), B(-2,3), and C(-5,3). If ABC is reflected across the y-axis to produce the image A'B'C', find the coordinate of the vertex C'.
Answer:
[tex]C' =(5,3)[/tex]
Step-by-step explanation:
Given
[tex]A = (-3,5)[/tex]
[tex]B = (-2,3)[/tex]
[tex]C = (-5,3)[/tex]
Reflection across y-axis
Required
Find C'
For reflection across y-axis, the rule is:
[tex](x,y) \to (-x,y)[/tex]
So, the image of C is:
[tex](-5,3) \to (-(-5),3)[/tex]
[tex](-5,3) \to (5,3)[/tex]
Hence:
[tex]C' =(5,3)[/tex]

Solve for x.
7x + 9
9x - 19
= X
Answer:
14
Step-by-step explanation:
7x+9= 9x-19
-2x= -28
x= 14
they are corresponding angles
Answer:
x = 14
Step-by-step explanation:
the angles are corresponding.
corresponding angles theorem states that when two parallel lines are cut by a transversal , the resulting corresponding angles are congruent.
therefore:
7x + 9 = 9x -19
9 = 2x - 19
28 = 2x
14 = x
In ADEF, the measure of ZF=90°, DF = 40, ED = 41, and FE = 9. What ratio
represents the secant of ZE?
E
41
9
D
40
Answer:
sec(∠F) = [tex]\frac{41}{9}[/tex]
Step-by-step explanation:
In triangle EFD,
m∠F = 90°
Adjacent side of ∠E = EF = 9 units
Opposite side of ∠E = DF = 40 units
Hypotenuse = DE = 41 units
For secant of ∠E ,
sec(∠E) = [tex]\frac{\text{Hypotenuse}}{\text{Adjacent side}}[/tex]
= [tex]\frac{41}{9}[/tex]
Therefore, [tex]\frac{41}{9}[/tex] is the ratio of secant of ∠F.

The expression 10+(-8) is equivalent to 10 - 8.
What is expression?Different branches of mathematics exist. The branch of knowledge that deals with numbers and operations is arithmetic. We learned how to add, subtract, multiply, and divide two or more numbers through arithmetic.
Shapes and how they are created with various tools, such as a compass, ruler, and pencil, are the focus of geometry. Another fascinating area of study is algebra, which helps us communicate the numerical and alphabetic aspects of daily life (variables).
Any mathematical statement made up of numbers, variables, and an operation between them is called an expression or an algebraic expression. As an illustration, the expression 4m + 5 consists of the terms 4m and 5, as well as the variable m, all of which are separated from one another by the arithmetic sign +.

how many numbers did bill wrote if he wrote all the natural numbers between w and v not including w and v
Answer:
v - w - 1
Step-by-step explanation:
Try an experiment with a small, specific set of numbers like:
4, 5, 6, 7, 8, 9, 10 w = 4 and v = 10.
There are 5 numbers in the list, not counting the first and last. Is this related to the difference between v and w? v - w = 6, one more than 5.
The number of natural numbers between w and v, not including w and v, is v - w - 1.
Tina paid for6 hours of canoeing and 1 life jacket rental with two twenty dollar bills. How much change did Tina get back
The amount of change that Tina got back would be = $10
How to calculate Tina's change after the bills payment?The amount of hours Tina spent in canoeing = 6 hours
The amount paid per hour for canoeing = $4
Therefore the total amount spent on canoeing = 6×4 = $24
The cost of the life jacket = $6
Therefore the total amount Tina spent = total amount spent on canoeing + cost of the life jacket.
That is; 24+6 = $30
The change Tina will receive from the two twenty dollars bills = (2×20) - 30
= 40-30 = $10
