If h is the number of hours you workey per day, and you earn $10.25 per hour, then, 10.25h is what you earn in a day due to the work.
However, you spend $4.00 round trip to get to and from work.
Hence, the expression to calculate the money you earn per day is given by:
\(10.25h-4\)y=2 x − 12 has how many real roots?
Answer: One root
Reason:
The term "root" refers to the x intercept.
We plug in y = 0 and solve for x to get the x intercept
y = 2x-12
0 = 2x-12
2x = 12
x = 12/2
x = 6
The root is 6.
The single x intercept is located at (6,0).
a box containing 8 shock absorbers and 10 brake pad sets weighs 101.6 lb
Answer:
10.16 lb
Step-by-step explanation:
This is a classic example of a problem that can be solved using dimensional analysis. To find the weight of a single shock absorber or brake pad set, you need to divide the total weight by the number of items in the box.
Weight of a single shock absorber = Total weight of shock absorbers / Number of shock absorbers in the box
= 101.6 lb / 8
= 12.7 lb
Weight of a single brake pad set = Total weight of brake pad sets / Number of brake pad sets in the box
= 101.6 lb / 10
= 10.16 lb
Therefore, a single shock absorber weighs 12.7 lb and a single brake pad set weighs 10.16 lb.

Answer:
Normally Distributed.
Explanation:
After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" not an answer. "correlated with a second set of data" is also wrong since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.

Using the formula developed by Dr's Mosteller, doctors can approximate the Body Surface Area TIW (BSA) of an adult The formula is written as BSA where H is the Height in cm and W is 3800 the Weight in kg: If the BSA of a certian adult is 96 whose height Is 210 cm. About how much does this adult weight? The adult weights (Round t0 decimal place )
From the body surface area formula, the adult weight is 508.97.
The Mosteller formula takes the square root of the height multiplied by the weight divided by 3600
The Body Surface Area TIW (BSA) of an adult.
The formula is written as BSA
where H is the Height(cm), Weight is 3800(kg)
BSA=96
Height=210cm
BSA=\(\sqrt{\frac{H*W}{3600} }\)
\(96=\sqrt{\frac{210*W}{3600} \\\)
\(96=\frac{\sqrt{210*W}}{\sqrt{3600} } \\96=\frac{14.49*\sqrt{W}\\}{61.64}\\ 96=\frac{\sqrt{W} }{0.235}\\ 96*0.235=\sqrt{W}\\ 22.56=\sqrt{W}\\\)
Squaring on both sides
508.97=W
Therefore, the adult weight is 508.97(kg).

Figure Y is the result of a transformation on Figure X. Which transformation would accomplish this?
A. a reflection over the x -axis
B. a rotation 90° clockwise about the origin
C. a rotation 180° counterclockwise about the origin
D. a translation 10 units to the left and 10 units down
A transformation would accomplish this include the following: C. a rotation 180° counterclockwise about the origin.
What is a rotation?In Mathematics and Geometry, the rotation of a point 180° about the origin in a clockwise or counterclockwise direction would produce a point that has these coordinates (-x, -y).
Furthermore, the mapping rule for the rotation of a geometric figure 180° counterclockwise about the origin is given by this mathematical expression:
(x, y) → (-x, -y)
Coordinates of point X (0, 4) → Coordinates of point Y = (0, -4)
Coordinates of point X (1, 3) → Coordinates of point Y = (-1, -3)
In conclusion, we can logically deduce that this transformation rule (x, y) → (-x, -y) would map Figure X onto Figure Y.

What is a parallelogram?A parallelogram is a four-sided shape with two sets of parallel sides, which means that opposite sides are both parallel and have equal length. Parallelograms also have opposite angles with the same measure, and their diagonals intersect at the midpoint and bisect each other. This results in the parallelogram being divided into two triangles that are congruent. Examples of parallelograms include rectangles, squares, and rhombuses, and they are commonly used in both geometry and everyday life, particularly in the design of buildings and other structures.
We can call this figure ACDEF. Let us join CB.
Now we can see that BDEF is a parallelogram. Opposite angles of a parallelogram are equal, hence ∠DBF = ∠DEF = x°
And also consider the triangle ABC,
∠BAC = 50°
∠ABC = 180 - ∠DBF = 180° - x° (linear pair)
∠ACB = 180 - ∠ACD = 180° - x° (linear pair)
We know that all the angles of a triangle adds up to 180°.
Using this we can find x°:
∠BAC + ∠ABC + ∠ACB = 180°
50° + 180° - x° + 180° - x° = 180°
-2x° + 410 = 180°
-2x° = 180° - 410° = -230°
x° = -230/ -2
x ° = 115°

QUICK! 40 points. Consider this cone with the diameter measure of 17 inches.
A cone with diameter 17 inches and slant height of 22 inches.
What is the surface area of the cone?
SA = Pir2 + Pirl
A. 204Pi in.2
B. 259.25Pi in.2
C. 446.25Pi in.2
D. 663Pi in.2
259.25π in² is the surface area of the cone
The surface area of a cone can be calculated using the formula SA = πr² + πrl
where r is the radius and l is the slant height.
Given that the diameter is 17 inches, the radius (r) is half of the diameter, which is 17/2 = 8.5 inches.
The slant height (l) is given as 22 inches.
Substituting these values into the formula:
Surface Area = π(8.5)² + π(8.5)(22)
= 72.25π + 187π
= 259.25π
Therefore, the surface area of the cone is 259.25π in²

How to determine the proportion of the variation in y that can be explained by the variation in the values of x?The complete question requires that we calculate the proportion of the variation in y that can be explained by the variation in the values of x
The given parameters in the question are:
The regression equation is reported as

a. The center of the circle is (-2, -1).
b. The radius of the circle is √136.
c. The equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.
a. To find the center of the circle, we can use the midpoint formula, which states that the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
In this case, the endpoints of the diameter are P(-7, -4) and Q(3, 2).Applying the midpoint formula:
Midpoint = ((-7 + 3)/2, (-4 + 2)/2)
= (-4/2, -2/2)
= (-2, -1)
Therefore, the center of the circle is at the coordinates (-2, -1).
b. To find the radius of the circle, we can use the distance formula, which calculates the distance between two points (x1, y1) and (x2, y2). The radius of the circle is half the length of the diameter, which is the distance between points P and Q.
Distance = √\([(x2 - x1)^2 + (y2 - y1)^2]\)
Using the distance formula:
Distance = √[(3 - (-7))^2 + (2 - (-4))^2]
= √\([(3 + 7)^2 + (2 + 4)^2]\)
= √\([10^2 + 6^2\)]
= √[100 + 36]
= √136
Therefore, the radius of the circle is √136.
c. The equation for a circle with center (h, k) and radius r is given by:
\((x - h)^2 + (y - k)^2 = r^2\)
In this case, the center of the circle is (-2, -1), and the radius is √136. Substituting these values into the equation:
\((x - (-2))^2 + (y - (-1))^2\) = (√\(136)^2\)
\((x + 2)^2 + (y + 1)^2 = 136\)
Therefore, the equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.

An alternative to a noun is a pronoun. In order to avoid using the noun more than once in a paragraph or piece of writing, it replaces. Singular and plural pronouns can be used. The verb in the sentence should be utilised in keeping with the specific pronoun form that is being employed.
The sentence is "Did you see it in the sky last night?".
"The spaceship" is the most appropriate option to replace the ambiguous pronoun reference in this statement.
Did you see it in the sky last night? is a vague question because "it" could refer to a variety of sky-observed objects.
The language becomes clearer and more precise by swapping "it" for "the spaceship," referring specifically to a particular item observed in the sky.
Therefore, the spaceship is the correct choice.
