Answer:
40.021
Step-by-step explanation:
Unlimited calls = $40
Text message = $0.021
NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.
Total cost = Cost of unlimited calls + cost of text messages
C = $40 + $0.021
= $40.021
Therefore, the equation which represent the total cost in dollars for a month is 40.021
A. 40.021
Answer:
maluna1999live is correct the answer is 40.021 so if your going to give someone the brailest then it should be maluna1999live

7. Melissa bought 8 yards of string to make bracelets. She wants to cut the string in equal pieces that is 1/2 yard
long. How many pieces of strings with Melissa have?
A 4
B 16
C 40
D 50
Please answer this it’s for a test and I suck in math I don’t even know how I’m in pre ap
Step-by-step explanation: To find this answer, you want to divide the amount of yards in half. This is the case since each string is 1/2. So as a result, each yard of whole string will produce 2 strings. To find your final answer, multiply 2 strings by 8 yards.

A concentrated cleaning solution must be mixed with water in a container that allows users to spray onto the surfaces they need to clean. Pam’s mom asked her to add 30 ounces of cleaning concentrate into the sprayer and then add water to fill the sprayer. Her father told her that the sprayer must contain 20% cleaning concentrate and 80% water.
a. How many ounces does the sprayer hold?
ounces
b. How much water was added to the sprayer?
ounces
Answer: The sprayer can hold 150 ounces, and Pam needs to add 120 ounces of water.
Step-by-step explanation:
The data that we know is:
We must use 30 oz of cleaning concentrate.
The end product must be 80% water and 20% cleaning concentrate.
This means that:
Mass of water/total mass in the sprayer = 0.8
mass of cleaning concentrate/total mass in the sprayer = 0.2
Then, let's define the variables:
X = ounces that the sprayer can hold.
Y = ounces of water added.
Then we have the equations:
30oz + X = Y.
30oz/Y = 0.20
X/Y = 0.80
From the second equation we can find the value of Y.
30oz = 0.20*Y
30oz/0.20 = Y = 150oz.
Then the sprayer can hold 150 ounces.
Now from the third equation we have:
X/Y = 0.8
We know that Y = 150oz
Then:
X/150oz = 0.8
X = 0.8*150oz = 120 oz.
Then the water that must be added is 120 ounces.
Ross said that if (x² + a)(x2 + b) = O means that (x2 + a) = 0 or (x2 + b) = 0, then(x+
a)(x2 + b) = 2 means that (x2 + a) = 2 or (x? b) = 2. Do you agree with Ross? Explain
why or why not.

Answer:
no; 2 has many factors besides 2
Step-by-step explanation:
The zero product rule says the only way a product may have a value of zero is if one or more factors is zero. That is why one of the factors of ...
(x^2 +a)(x^2 +b) = 0
must have a value of 0.
__
The same cannot be said of 2. We might have (1/2)(4) = 2, for instance, in which neither factor is 2. That a product is 2 is not a requirement that one of the factors be 2.

Joseph borrowed a book from a library. The library charged a fixed rental for the book and a late fee for every day the book was overdue. The expression below shows the charges Joseph paid for the book when he returned it x days after the due date:
2 + 0.25x
What does the coefficient of the expression represent?
A:The fixed rental for the book
B:The total late fee for the book
C:The late fee per day for the book
D:The number of days the book was overdue
Answer:
C. The late fee per day for the book
Step-by-step explanation:
“ The library charged a fixed rental for the book and a late fee for every day the book was overdue.”
Answer:
C
Step-by-step explanation:
the problem says there is a late fee for every day the book is overdue, 'x' represents the days, so multiplying the two together filling in 'x' would give you the total late fee amount.

a rectangular tank is 76cm long, 50cm wide and 40cm high, how many litres of water can it hold?
Answer:
Volume of a cuboid or rectangular tank = side × side × side
or
volume of a cuboid or rectangular tank = length× width × height
volume of the rectangular tank = 76 × 50 × 40
volume of the rectangular tank = 152000cm³
Therefore the rectangular tank can hold 152000cm³ litres of water
Composite functions
g(d) = 2d - 5
h(d) = -4d +3
Find (hºg)(d)
Answer:
[tex](h\circ g)(d)=-8d +23[/tex]
Step-by-step explanation:
Composite Function
Given g(d) and h(d) real functions, the composite function named (hog)(d) is defined as:
[tex](h\circ g)(d)=h(g(x))[/tex]
For practical purposes, it can be found by substituting g into h.
The functions g and h are given as:
[tex]g(d) = 2d - 5[/tex]
[tex]h(d) = -4d +3[/tex]
Substituting g into h:
[tex](h\circ g)(d)=-4(2d - 5) +3[/tex]
Operating:
[tex](h\circ g)(d)=-8d +20 +3[/tex]
[tex]\boxed{(h\circ g)(d)=-8d +23}[/tex]

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam?
Given :
Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.
To Find :
The total number of questions on Stephanie's exam.
Solution :
Let, number of questions in Part 1 is x :
[tex]16=\dfrac{4}{5}x\\\\x=20[/tex]
Let, number of questions in Part 2 is y :
[tex]16=\dfrac{2}{3}y\\\\y=24[/tex]
Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.
Hence, this is the required solution.

Which equations represent the line that is parallel to 3x - 4y = 7 and passes through the point (-4,-2)? Select two
options
y=-3/4x+1
3x - 4y = -4
4x - 3y = -3
y-2 = -3/4(x - 4)
y+2 =3/4(x + 4)
Answer:
y = 3/ 4 x + 1
Step-by-step explanation:
Write a system of linear equations that has (-4, 8) as the solution. Once you have made your system of equations, solve it algebraically to show that you do indeed get the solution (-4, 8).
Answer:
See below
Step-by-step explanation:
(-4, 8) has to be the solution.
1st equation: -4x+8y = 1
2nd equation: 8x - 4y = 1
These should work. Do the matrix-substitution combo method to see:
-4 8 1
.8 -4 -1
Reduce and and matrix-substitution combo:
1 0 -4
0 1 8
The reduced eckerd form of the matrix shows that the solutions are (-4, 8)
Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.

Why because like 3 my favorite number and i had this same problem and the answer was 3.
how do you simplify this?
Answer:
tan x
Step-by-step explanation:
(tan-x)[sec(pi/2)-x] (sin-x)
We know that tan (-x) = - tan (x) and sin (-x) = - sin (x)
-(tanx)[sec(pi/2)-x] -(sinx)
(tanx)[sec(pi/2)-x] (sinx)
Using the identity sec = 1/ cos
sec ( pi/2 -x) =1/cos ( pi /2 -x)
We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)
1/ ( cos pi/2 cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx
Replacing into the equation
(tanx)[1/ sinx] (sinx)
tan x

a. The line is parallel to y=3x+2 and passes through the point (0,0).
b. The line is perpendicular to the graph of y=x+1 and passes through the point (1,1).

A researcher needs 25 mL or 45%
base Solution for a certain
expiriment, but she has only 15%
Solution and 65% Solution. How
many mL of the 15% and the
65% Solutions should she mix to
get what She needs?
Answer:
10 mL of 15% solution
15 mL of 65% solution
Step-by-step explanation:
If x is the volume of 15% solution, and y is the volume of 65% solution, then:
x + y = 25
0.15 x + 0.65 y = 0.45 (25)
Solve with substitution:
0.15 x + 0.65 (25 − x) = 0.45 (25)
0.15 x + 16.25 − 0.65 x = 11.25
0.50 x = 5
x = 10
y = 15
