Jose is driving to Denver. Suppose that the remaining distance to drive (in miles) is a linear function of his driving time (in
minutes). When graphed, the function gives a line with a slope of -0.95. See the figure below.
Jose has 48 miles remaining after 50 minutes of driving. How many miles were remaining after 34 minutes of driving?
Answer:
63.2 miles
Step-by-step explanation:
The given slope and point can let us use the point-slope form of the equation for a line:
y = m(x -x1) +y1
y = -0.95(x -50) +48
We want to find the value of y for x=34.
y = -0.95(34 -50) +48 = 63.2
Jose had 63.2 miles remaining after driving 34 minutes.

6/4 as a whole number or a mixed nimber
Answer: 1 2/6 which needs to be simplify which is 1 1/3.
We can see here that 6/4 as a mixed number is = 1 (1/2).
What is mixed number?A mixed number is a representation of a number that includes both a whole number and a fraction. It consists of an integer part and a fractional part. The integer part represents a whole number, while the fractional part represents a proper fraction.
To express 6/4 as a mixed number, you divide the numerator (6) by the denominator (4) and express the remainder as a fraction with the same denominator. In this case, 6 divided by 4 is 1 with a remainder of 2. So, 6/4 can be written as the mixed number 1 (2/4), which can be simplified to 1 (1/2).

Step-by-step explanation:
since Y is 3x, then substitute the y with 3x which is 2*3x=5x and then plus the 5x which is 11x in total which equals to 44 (11x=44) then divide that you get: x=11.
Answer:

substitute the value of y
5x+2(3x)=44
5x+6x=44
11x=44
divide both sides by 11

the end of the year, after taxes, a manufacturing firm has $230,000 in revenues, $90,000 in production costs, and $140,000 in opportunity costs. How much economic profit did the firm make?
Answer: 50
Step-by-step explanation:
Final answer:
The firm's economic profit is calculated by subtracting both explicit and implicit costs from the total revenues. Upon performing this calculation, we determine that the firm made an economic profit of $0 since the costs equaled the revenues.
Explanation:
To calculate the economic profit of the firm, we subtract both explicit (actual monetary payments) and implicit (opportunity) costs from the total revenues. The firm has $230,000 in revenues after taxes, $90,000 in production costs (explicit costs), and $140,000 in opportunity costs (implicit costs). Therefore, the calculation for economic profit is as follows:
Total Revenues - Explicit Costs - Implicit Costs = Economic Profit
$230,000 - $90,000 - $140,000 = $0
So, the firm did not make any economic profit, as the explicit and implicit costs equaled the total revenues.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 8) = 72. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 8 = 72. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seventy-nine ninths plus thirty-three eighths = nine hundred twenty-nine seventy-seconds.

A bag contains two red marbles and three blue marbles. You randomly pick a marble. Find the number of possible outcomes in the sample space.
Final answer:
The sample space for picking a single marble from a bag containing two red and three blue marbles has 5 outcomes, represented as R1, R2, B1, B2, B3.
Explanation:
To determine the number of possible outcomes in the sample space when you randomly pick a marble from a bag containing two red marbles and three blue marbles, you must consider each marble as a distinct possibility. Since there are 5 marbles in total, each draw from the bag has 5 potential outcomes. It does not matter the color of the marble; each draw represents a distinct event with 5 possible outcomes.
Therefore, the sample space, which represents all possible outcomes, contains 5 elements. These outcomes can be represented as R1, R2, B1, B2, and B3, where 'R' stands for red marbles, 'B' stands for blue marbles, and the numbers differentiate between the individual marbles.
Josie and her brother, Sean both have a job after school. For every $5.50 that Josie earns, her brother earns $6.50. On Tuesday, they earned $30.00. How much money did Josie earn? How much did her brother earn?
Answer:
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
Step-by-step explanation:
Let
x ----> amount earned by Josie
y ---> amount earned by her brother
we know that
[tex]\frac{x}{y}=\frac{5.50}{6.50}[/tex]
[tex]x=\frac{5.50}{6.50}y[/tex] ------> equation A
[tex]x+y=30.00[/tex] -----> equation B
Solve the system by substitution
Substitute equation A in equation B
[tex]\frac{5.50}{6.50}y+y=30.00[/tex]
solve for y
[tex]\frac{12.00}{6.50}y=30.00[/tex]
[tex]y=6.50(30.00)/12.00\\y=\$16.25[/tex]
Find the value of x
[tex]x=\frac{5.50}{6.50}(16.25)\\\\x=\$13.75[/tex]
therefore
The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25
Answer:
Step-by-step explanation:
Given that For every $5.50 that Josie earns, her brother earns $6.50.
Tuesday, they earned $30.00
Using the ratio and the proportional
Josie : Sean : Total
5.5 : 6.5 : 12
x : y : 30
So, x = 5.5 * 30/12 = 13.75
And y = 6.5 *30/12 = 16.25
So, Josie will earn $13.75 and her brother Sean will earn $16.25

20,610
23,900
Answer:
11679
Step-by-step explanation:
Increased by 229
First you need to find the 2%
So to find the 2%
2/100 * 11450=229
Now add 11450+229= 11679
Answer:
11,679
Step-by-step explanation:
Start off making the 2% into a decimal so you can multiply it with the full amount of applications for the year before. 2% in decimal is .02 because you move the decimal twice to the left. Now that you have .02, multiply it by 11,450. (11,450)*(.02) which should be 279. Now you have to add the 279 to the 11,450 because they were admitted as well. (11,450+279)= 11,679

[tex]50(5 - 3x)[/tex]
Step-by-step explanation:
The given expresion is

The greatest common factor is 50.
We rewrite using the distributive property to get;
[tex]50 \times 5- 50 \times 3x[/tex]We collect the highest common factor to obtain:
