Answer:
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.

Step-by-step explanation:
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.

Lines AB and CD are perpendicular to each other. If 3 measures (5x + 2)°, and 4 measures 13°, what is the value of x?
A.
x = 15
B.
x = 77
C.
x = 2
D.
x = 21
Answer:
A is the correct option.
Step-by-step explanation:
Since both lines are perpendicular to each other, that means the sum of their angles is equal to 90°.
Then,
(5x + 2) ° + 13° = 90°
5x + 15° = 90°
5x = 75°
x = 15°

Answer: 20
Step-by-step explanation:
*This is a supplementary Angle (adds up to 180 degrees)
5x+12+68=180
5x+80=180
*subtract 80 on both sides
5x=100
*divide both sides by 5

The equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3
The equation of a line in slope intercept form is expressed as:
[tex]y-y_0 = m(x-x_0)[/tex]
m is the slope
(x0, y0) is the point on the line.
Given the following parameters:
m = -5/2 and (x0, y0) =(-4, 7)
Substitute the given coordinates into the formula above;
y - 7 = -5/2(x + 4)
2(y-7) = -5(x+4)
2y-14 = -5x - 20
2y = -5x - 20 + 14
2y = -5x - 6
y = -5/2x - 3
Hence the equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3

Nathan lifted 13 boxes, each weighing 12 lb more than Steven's boxes. Steven lifted 15.
The total weight of Nathan's boxes would be the weight of 1 box times 13, because he lifts a total of 13 boxes.
S is the weight of Steven's boxes.
Steven's box + 12 lb = the weight of one of Nathan's boxes.
Then, you would multiply that number by 13 to get your answer.
Therefore, the first option is correct.
13(s + 12)
number of boxes Nathan lifted(Steven's weight + the extra pounds)

Rearrange x = 3g + 2 to make g the subject.
Answer:
In order to make g as the subject, we have only g on the left side and rest of the terms are denoted on the right. So, we consider it as X=3g+2 and switch to other side's 3g+2=x. It has to divide both sides by 3 and literally consider for g=1/3x-2/3 and therefore answer is g=1/3X-2/3.

-3x + b = 6x
solve for x
Answer:
x = 1/9(b)
Step-by-step explanation:
Step 1: Subtract 6x from both sides.
[tex]-3x + b - 6x = 6x - 6x[/tex] [tex]-9x + b = 0[/tex]Step 2: Subtract b from both sides.
[tex]-9x + b - b = 0 - b[/tex] [tex]-9x = -b[/tex]Step 3: Divide both sides by -9.
[tex]\frac{-9x}{-9}= \frac{-b}{-9}[/tex] [tex]x = \frac{1}{9}b[/tex]Therefore, [tex]x = \frac{1}{9}b[/tex].

A market research firm is studying the effects of price and type of packaging on sales of a particular product. Twenty-seven stores with shoppers of similar characteristics will be used in the study. The nine combinations of three price levels and three packaging types are the treatments of interest. Total sales of the product over a seven-week period will be recorded. Which of the following describes the best design to use for the study?
a. А A completely randomized design Randomly assign the nine combinations of price level and packaging type that three stores use each combination
b. A completely randomized design. Randomly assign the three price levels so that nine stores use each price level
c. A completely randomized design. Randomly assign the three packaging types so that nine stores use each type of packaging
d. A randomized block design Use packaging as a block. Randomly assign the nine combinations of three price levels and three packaging types so that three stores use each combination
e. A randomized block design. Use packaging as a block Randomly assign nine stores to each packaging type, then randomly assign price level to three stores within each block.
The market research can increase the precision of the result of the study by
using a randomized block design RBD
The best design the market research company should use for the study is
d. A randomized block design Use packaging as a block. Randomly assign
the nine combinations of three price levels and three packaging types so
that three stores use each combination
Reason:
The given parameters are;
The study = The effect of price and type of packaging
Number of stores in the study = 27 stores
Characteristics of the shoppers in the stores = Similar
Number of packaging type = 3 (three)
Number of price levels = 3 (three)
The number of pair combinations = ⁶₂C - (3, pairs of the same packaging +
3, pairs of the same prices) = 9
Required:
The best design to use for the study
Solution:
Given that the shoppers at each store are similar, in order to differentiate
and show the effect of the price and package combination, it is possible to
group the treatment into groups having a particular characteristics, while
ensuring that the other available treatments are assigned to each member
within a group at least once.
The above design of the study is known as a randomized block design,
therefore;
The correct option is d. A randomized block design Use packaging as a
block. Randomly assign the nine combinations of three price levels and
three packaging types so that three stores use each combinations.

explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds. What is the value of x?
Answer:
me too jaja
Step-by-step explanation:
The value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
A shipwreck is 300 meters away from a diving station.
An undersea explorer travels away from the station at a speed of 2 meters per second.
The explorer is x meters away from the station and will reach the
shipwreck in 100 seconds.
As we know,
Distance = time×speed
Distance = 100×2
Distance = 200 meterse
x = 300 - 200
x = 100 meters
Thus, the value of x is 100 meters if the shipwreck is 300 meters away from a diving station. An undersea explorer travels away from the station at a speed of 2 meters per second.
