Lauren is working two summer jobs, making $11 per hour washing cars and $6 per hour walking dogs. Lauren must earn no less than $120 this week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours walking dogs, d, that Lauren can work in a given week
Answers
Answer:
11w + 6g ≥ 120
Step-by-step explanation:
Let's set:
w = number of hours Lauren spent washing cars
d = number of hours Lauren spent walking dogs
Lauren makes $11 per hour washing cars, thus she earns 11w in total for washing cars.
Lauren makes $6 per hour walking dogs, thus she earns 6d in total for walking dogs.
The total earnings are:
T = 11w + 6g
Lauren must earn not less than $120 this week, thus:
11w + 6g ≥ 120
This is the required inequality
Answer:
11w+6d≥120

Answer: -5/14k-2
Step-by-step explanation:
We can get rid of the parenthesis because addition and subtraction are commutative. Therefore we get, -6/7k-7+5+1/2k
First combine the k's by forming a common denominator: -12/14k+7/14k=-5/14k
Now combine the constants: -7+5=-2
Next, combine the variables and constants: -5/14k-2
Therefore, our answer is -5/14k-2
Specify the component functions of a vector field →F in R2 with the following property. →F is everywhere normal to the line x=2. Which of the following is one possible vector field →F ?
A. →F=(x,0)
B. →F=(−y,x)
C. →F=(x,y)
D. →F=(0,y)
Answers
Option D has a non-zero component function in the y-direction and a zero component function in the x-direction.
The vector field →F is normal to the line x=2, so it must be tangent to the line y-axis at every point. This means that the component function of →F in the x-direction should be 0 and the component function of →F in the y-direction should be non-zero.
Option D has a non-zero component function in the y-direction and a zero component function in the x-direction, so it satisfies the given property. Therefore, the answer is: D. →F=(0,y)

0.83
Answers
Answer:
0.56
Step-by-step explanation:
The r-value that represents the most moderate correlation is 0.56
How to determine the moderate correlation value?Correlation is represented with r.
And the range of values of r is:
-1 ≤ r ≤ 1
This means that r can take any value from -1 to 1
-1 and 1 are considered strong correlation
While values closer to 0.5 or - 0.5 are moderate
From the list of options,
0.56 is closer to 0.5 than others
Hence, the r-value that represents the most moderate correlation is 0.56

What sort of mathematical inequality is this?The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. The left half, 5x 4, is larger than the right half, 2x + 3, as evidenced by this.
To solve the inequality, we need to isolate the variable, x, in the middle of the inequality.
Starting with:
-4 < 3x + 5 ≤ 11
Taking out 5 from each component of the inequality:
-4 - 5 < 3x + 5 - 5 ≤ 11 - 5
Simplifying:
-9 < 3x ≤ 6
Dividing by 3 (and remembering to reverse the direction of the inequality if we divide by a negative number):
-3 < x ≤ 2
Therefore, the solution to the inequality is:
-3 < x ≤ 2

if x is a discrete uniform random variable ranging from one to eight, find p(x < 6).
Answers
The probability that x is less than 6 is 5/8.
If x is a discrete uniform random variable ranging from one to eight, then each value from one to eight is equally likely to occur, and the probability of any particular value is 1/8.
To find p(x < 6), we need to add up the probabilities of all the values of x that are less than 6:
p(x < 6) = p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4) + p(x = 5)
Since x is a discrete uniform random variable, the probability of each of these values is 1/8, so we can substitute that into the equation:
p(x < 6) = (1/8) + (1/8) + (1/8) + (1/8) + (1/8)
Simplifying, we get:
p(x < 6) = 5/8
Therefore, the probability that x is less than 6 is 5/8.

After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 1700 feet under water. After ascending for 6 hours, they are 1580 feet below the surface of the water. (Note: under the water is negative)
Write an equation to model this situation (use d for depth in meters and x for hours).
Answers
Answer:
d = -20x + 1700
Step-by-step explanation:
First, you need to identify how many meters the submarine travels in an hour. In order to figure this out, you need to know how far they traveled in 6 hours.
In 6 hours, they traveled 1700-1580 meters or 120 meters.
If you divide both values by 6, you'll get that they traveled 20 meters every hour. Now you can write the equation:
depth = 1700 meters - 20 meters (# of hours)
d = 1700 - 20x

The volume of the box is 60 cubic inches. What are
the length, width, and height of the box?
Answers
Answer: The volume is the product of the Length, Width, and Height: V = LWH.
Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.
Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2
Using the distributive property and moving the constant to the left gives:
W2 + (3 in.)W - 40 in.2 = 0
This factors:
(W + 8 in.)(W - 5 in.) = 0
The first factor gives W = -8 in. which is nonsense because it is negative.
The second factor gives a valid answer of W = 5 in.
Scientists have found a relationship between the temperature and the height above a distant planet's surface. T(h), given below, is the temperature in Celsius at a height h kilometers above the planet's surface. The relationship is as follows:
T(h)=41−1.25h.
Let T^−1 be the inverse function of T. Take x to be the output of the function T.
a) Explain the meaning of T^−1(x).
b) Find T−1(x).
c) Find T−1(30)
.
Answers
a) The inverse function is obtained by rearranging the variables for temperature and height in the given equation.
b) T⁻¹(x) =41-x/1.25
c) T⁻¹(30) =8.8
The given function is T(h)=41- 1.25h, so the inverse of a function is just obtained by rearranging the variables for height and temperature, the variable of temperature is replaced by height and vice versa. for the second
T(h)=41- 1.25h, considering h= x
=>T(x)=41- 1.25x
setting T(x)=x and x= T(x), we get
41- 1.25T(x) =x
=>1.25T(x) =x -41
=>T(x) =x- 41/ 1.25
now setting T(x)= T⁻¹ (x) we get : T⁻¹ (x) =41-x/1.25
For T⁻¹(30) =41-30/1.25= 11/1.25 =8.8
