Answer:
Step-by-step explanation:
One clue about where to start is this: the sentence describes the length by referring to the width. "The LENGTH is blah, blah, blah, the WIDTH. When that happens, choose a variable to represent the width (the quantity being referred to).
Width = w
Length IS three more than (added to) 4 times (multiplied by) the width
Length = 4w + 3
Area of a rectangle is the width multiplied by the length.
Equation: w(4w + 3) = 24
Solve.
Multiply out the left side.
4w^2 + 3w = 24
Subtract 24.
4w^2 + 3w -24 =0
This equation does not factor. Use the Quadratic Formula. One of the solutions is a negative number, so that should be rejected (width can't be a negative number).
[tex]w=\frac{-3+\sqrt{393}}{8}[/tex]
Substitute this into the expression 4w + 3 to find the length. A calculator can give you decimals for both dimensions.

David has a monthly after-tax income of $ 1430.15 1430.15 . He will be using the companies health insurance plan which costs $ 63 63 a monthand the retirement option which takes 7 7 % of his after tax income. Calculate David's Monthly Take-Home pay.
Answer:
$ 1267.
Step-by-step explanation:
Given :
David's monthly income after tax = $ 1430.15
His health insurance cost him in a month = $ 63
Percent deducted from his income after tax for his retirement option is = 7%
Therefore money left after retirement option deduction is :
$ 1430.15 - 7% of $ 1430.15
= 1430.15 - 100.11
= $ 1330.04
= $ 1330 (aprrox)
Money deducted from this amount for his health insurance plan
= $ 1330 - $ 63
= $ 1267
Therefore, David's monthly take home pay is $ 1267.

Answer and Step-by-step explanation:
When we take a look at the graph, we can see that at around 1 gallon, which would be halfway between 0 and 2, the line is underneath $5.
That means we can eliminate any number that is or above $5.
That leaves us with answer choices A and C.
Let's go to a point that is easily readable. Point (4, 15) is readable, and we can use this to find the price per gallon.
Divide 15 by 4. We get 3.75 as the result.
This means that the answer choice is:
C. The cost of gas is $3.75 per gallon.

At an assembly 7 out of the first 10 students who entered the gym were carrying a backpack.
Based on this information, if 700 students were at the assembly, how many students could be expected to be carrying a backpack?
Record your answer on the keypad and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer: 490
Step-by-step explanation: If 7 out of ten students have a backback you can also say 7/10. If in total there are 700 students we can multiply 7/10 or .7 woth 700 and get the answer. (7/10)(700)=490

Step-by-step explanation:
For purposes of making on-campus housing assignments, a college classifies its students as Priority A (seniors), Priority B (juniors), and Priority C (freshmen and sophomores). Of the students who choose to live on campus, 22% are seniors, 29% are juniors, and the rest are underclassmen. The most desirable dorm is the newly constructed Gold dorm, and 71% of the seniors elect to live there. 19% of the juniors also live there, along with only 5% of the freshmen and sophomores. What is the probability that a randomly selected resident of the Gold dorm is a senior? Show as much work as possible.
Answer:
The probability that a randomly selected resident of the Gold dorm is a senior is 0.1562
Step-by-step explanation:
The given percentage of each class of student is presented as follows;
Priority A (seniors) = 22%, ∴ P(s) = 0.22
Priority B (juniors) = 29%, ∴ P(j) = 0.29
Priority C (freshmen and sophomores) = (100 - 22 - 29)% = 49%, ∴ P(fs) = 0.49
The percentage of the seniors that elect to live at the Gold dorm, = 71%, ∴ P(sG) = 0.71
The percentage of the juniors that live at the Gold dorm = 19%, ∴ P(jG) = 0.19
The percentage of the freshmen and sophomores that live in the Gold dorm = 5%, ∴ P(fsG) = 0.05
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = P(s) × P(sG)
∴ P(s∩sG) = 0.22 × 0.71 = 0.1562
Therefore;
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = 0.1562.

Find the ordered pair that is a member of both -2x + 6y = 34 and
2x + 2y = 14 or indicate if it does not exist or there are infinite
possibilities.
Answer:
(1, 6) is the solution
Step-by-step explanation:
-2x + 6y = 34
2x + 2y = 14; divide by 2
x + y = 7; subtract x
y = 7 - x
let's substitute y with 7 - x in first equation
-2x + 6*(7 - x) = 34; expand multiplication
-2x + 6*7 - 6*x = 34; group
-8x + 42 = 34; subtract 42
-8x = 34 - 42 = -8; divide by -8
x = 1
y = 7 - 1 = 6
It is the only solution, as we've arrived at exact numbers.

30 $24.25
What is the equation that relates the cost, C(t), of the taxi ride and time, t, in minutes? What is the cost of a 42-minute taxi ride? (7 points)
C(t) = 0.55t + 7.75, $30.85
C(t) = 1.71t + 7.75, $79.57
C(t) = 0.775t + 5.50, $38.05
C(t) = 5.5t + 0.775, $231.78
Answer:
C(t) = 0.55t + 7.75, $30.85
Step-by-step explanation:
the fixed cost is $7.75. this is the cost incurred at zero minutes of the taxi ride
the variable cost or the cost per minutes driven =
(13.25 - 7.77) / (10 - 0) = 0.55
total cost = 7.75 + 0.55t
cost of 42 minutes = 7.75 + 0.55(42) = $30.85

What is the difference between the cost of 15 visits with and without a membership? Show your work swimming
Question is incomplete :
It costs $4 to go to the swimming pool
The cost of n visits =
Membership at the pool costs $21. Members pay $3 each time. WHAT is The cost for a member to swim including membership fee?
What is the difference between the cost of 15 visits with and without a membership?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Swimming cost = $4
Cost of swimming n Times = cost per swim * number of swims
= $4 * n
= $4n
Membership cost = $21
Cost per swim for members = $3
Swimming cost including membership fee :
21 + 3n ; n = number of visits
For 15 visits ; n = 15
Amount paid :
Members = 21 + 3(15) = 21 + 45 = $66
Non - Member = 4(15) = 60
Difference :
$66 - 60 = 6
Members incur $6 more than non - members
