Answer:
The interval over which the cost is constant is from >0 to 15,000 gallons
The interval for which the the cost is increasing is from above 15,000 gallons
Step-by-step explanation:
For 15,000 gal or less the cost of the monthly water bill = $15.50
For over 15,000 gal, the cost of the monthly water bill = $15.50 plus $1 for each 1000 gal over 15,000 with any fraction of $1,000 charged at a fraction of $1
The interval for which the cost is constant is from 0 ≤ x ≤ 15,000 gal
The interval over which the const is increasing per 1000 gal over 15,000 gallons is from x > 15,000 gal.
Answer:
The interval in which the cost is constant is
[0,15000]
Step-by-step explanation:
The interval is increasing by [1500,∞]

A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
The building to the left is taller.
Step-by-step explanation:
Building on right:
tan 40° = a/56
a = 56 tan 40° = 46.99
Building on left:
tan 50° = b/49
b = 49 tan 50° = 58.40
The building to the left is taller.

Answer:
The exact answer is 10 pi km
Step-by-step explanation:
The circumference of a circle is given by
C = pi * d
C = pi * 10
C = 10 pi
The exact answer is 10 pi km
Answer:
circumference formula=2pi r
finding radius using diameter
r=d/2
r=10km/2
r=5km
now putting the value of r in circumference formula
c=2 pi r
c=2×3.14×5km
c=31.4km

X = 3.4(01.05)
What is the equation of a horizontal line passing through the point (-3, 8)?
A: x=-3
B: y=8
C: x=5
D: y=-11
Answer:
B
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, 8 ) with y- coordinate of 8, thus
y = 8 ← equation of horizontal line

(01.06) Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= 3x − 3 The function g(x) going through 0, 2 and 1, 5 (1 point) The function f(x) has a larger slope. The function g(x) has a larger slope. They both have the same slope. The relationship between slopes cannot be determined.
Answer:
They both have the same slopeStep-by-step explanation:
The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.
given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;
mx = 3x
Divide through by x
mx/x = 3x/x
m = 3
Hence the slope of the function f(x)= 3x − 3 is 3.
For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;
m = Δy/Δx = y₂-y₁/x₂-x₁
From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5
m = 5-2/1-0
m = 3/1 = 3
Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.
This shows that both functions have the same slope.
how does 1/12 - 5/6 = 9/12 um tring to learn how to add this like ?
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
1st, we need to identify the Least Common Multiplier of 12 and 6
in this case, the LCM is 12
for 5/6 = (5*2) / (6*2) = 10/12
2nd, adjust the fractions based on the LCM
= 1 / 12 - 10 / 12
= 1 - 10 / 12
= -9 / 12 ---- simplify -3 / 4

Answer:
5x^2 + -3
Step-by-step explanation:
For this problem, we will simply simplify the expression by combining like terms.
(-3x^3 - 7x^5 - 3) + (5x^2 + 3x^3 + 7x^5)
= 7x^5 + -7x^5 + 3x^3 + -3x^3 + 5x^2 + -3
= 0 + 0 + 5x^2 + -3
= 5x^2 + -3
Thus, the simplified expression is 5x^2 + -3.

Please help. If CJ=8x+5 CT=55, and JT=4x+2 Find JT
Answer:
- 56
Step-by-step explanation:
JT = CJ + CT
4x + 2 = 8x + 5 + 55
4x + 2 = 8x + 60
4x - 8x = 60 - 2
- 4x = 58
x = 58/-4
x = -29/2
x = - 14.5
JT = 4x + 2 = 4(-14.5) + 2 = - 58 + 2 = - 56
A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer monitors are produced each day. In a random sample of 240 computer monitors, there are 2 defective computer monitors. Determine whether the manager's claim is likely to be true. Explain.
Answer:
The manager's claim is likely to be true.Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct
Jacob bought 7 t-shirts for $32.90. Gwen bought 12 t-shirts for $60. Their friend Lia found a store online where she can buy a package of 8 t-shirts. These shirts sell at the same rate as the shirts Jacob bought. How much does Lia pay for the package of 8 t-shirts?
Answer:
$37.60
Step-by-step explanation:
If 7 shirts = 32.90 then (32.90/7) x 8 = 37.60
y =6x-15
Please help
Answer:
y=15+-6x
Step-by-step explanation:
y = -6x + 15
Reorder the terms:
y = 15 + -6x
Solving
y = 15 + -6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 15 + -6x
Step-by-step explanation:
[tex]6x - 15 = y \\ 6x = y + 15 \\ \frac{6x}{6} = \frac{y + 15}{6} \\ x = \frac{y + 15}{6} \\ x = \frac{y}{6} + \frac{5}{2} [/tex]

Mark would like to build a rectangle frame. The dimensions of the frame are unknown, but the perimeter of the frame must be 80 yards. The length of the frame is six less than the width. What is the length of the frame?
Answer:
The length of the frame is 17
Step-by-step explanation:
The computation of the length of the frame is shown below:
As we know that
The perimeter of a rectangle is
= 2 (length + width)
where,
let us assume the width be x
So, the length is x - 6
And, the perimeter is 80 yards
So, now put these values to the above formula
80 yards = 2 (x - 6+ x)
80 yards = 2 (2x - 6)
80 yards = 4x - 12
92 = 4x
x = 23
So, the length of the frame is
= 23 - 6
= 17
To which subset of the real number system does the number LaTeX: 1.\overline{5}1. 5 ¯ belong?
Answer:
The subset of rational numbers
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b where ad b are integers. The number [tex]1.\overline5[/tex] is a number with a recurring decimal of 5 and every recurring decimal can be expressed in the form a/b where a and b are both integers therefore, every number with recurring decimal is a rational number.
In the question, [tex]1.\overline5[/tex] can be written as follows;
[tex]1.\overline5 = \dfrac{14}{9}[/tex] or [tex]1.\overline5 = 1\dfrac{5}{9}[/tex].
