The student's conversion calculation of speed units from kilometers per minute to miles per hour yields a speed of 2.4 miles/hour, so the answer is choice A.
Explanation:The question is a conversion exercise in speed units from kilometers per minute to miles per hour. We have the following information: 3.2 km in 50 min, and we know that 1 mile is equivalent to 1.6 km and 60 min is equivalent to 1 hour. Thus, the conversion is as follows:
3.2 km ÷ 50 min. = 0.064 km/min.
Converting km/min to mi/hr involves multiplying by 60 (minutes in an hour) and dividing by 1.6 (km in a mile), and we get:
(0.064 km/min x 60 min/hr) ÷ 1.6 km/mi. = 2.4 mi/hr.
Hence, the correct answer is (A) 2.4 miles/hour.

Find the surface area
A right triangle has sides measuring 5 inches, 12 inches, and 13 inches. What is the area, in square inches, of this triangle ?
Final answer:
The area of a right triangle with sides of 5 inches and 12 inches as the base and height, respectively, is 30 square inches, calculated using the formula A = (base × height) / 2.
Explanation:
The area of a right triangle is calculated by multiplying one-half the base by the height: A = (base × height) / 2.
In the case of a right triangle with sides measuring 5 inches, 12 inches, and 13 inches, the 5-inch and the 12-inch sides are the legs and thus can be used as the base and height. Using the formula for the area of a right triangle:
A = (5 × 12) / 2
A = 60 / 2
A = 30 square inches
Therefore, the area of this triangle is 30 square inches.
A plane intersects a double-napped cone such that the plane intersects both nappes through the cone's vertex. which terms describe the degenerate conic section that is formed? select each correct answer. degenerate parabola pair of intersecting lines point line degenerate hyperbola degenerate ellipse
Answer with explanation:
It is given that, a plane intersects a double-napped cone such that the plane intersects both Nappes through the cone's vertex.It also depends on how thick or thickness of the plane:
1.We can surely say that degenerate hyperbola will be formed,whatever be the thickness of Plane.
2. Two parallel lines=pair of intersecting lines ,because both ,A double napped cone and Plane is three dimensional shape.Instead of intersecting lines ,two parallel lines which we call pair of intersecting lines, will be formed.

The ratio of gold charms to silver charms is 1:3. Which statement does not describe the relationship?
The ratio of gold charms to silver charms is 1:3, with 1 representing the number of gold charms and 3 representing the number of silver charms. The statement that does not describe the relationship is the one that does not accurately represent this ratio.
Explanation:The ratio of gold charms to silver charms is 1:3. In this ratio, the first number (1) represents the number of gold charms, and the second number (3) represents the number of silver charms. Therefore, the statement that does not describe the relationship is the one that does not accurately represent this ratio.
Find the equation of the line whose x-intercept is 8 and y-intercept is -2. write the equation in slope-intercept form.
To determine the equation of the line with x-intercept 8 and y-intercept -2, the slope is calculated to be 1/4. Thus, the line's equation in slope-intercept form is y = (1/4)x - 2.
To find the equation of a line with an x-intercept of 8 and a y-intercept of -2, we'll first determine the slope of the line (m) and then use the slope-intercept form (y = mx + b).
Two points on this line are (8,0) and (0,-2). The slope (m) of a line is calculated by the change in y divided by the change in x, which in this case is
(0 - (-2)) / (8 - 0) = 2 / 8 = 1 / 4.
Now we know the slope is 1/4 and the y-intercept (b) is -2, so the equation of the line in slope-intercept form is:
y = (1/4)x - 2

Find the 12th term in the following geometric sequence. 0.75, 1.5, 3, 6, . . .
Answer:
1536
Step-by-step explanation:
Given : A geometric sequence 0.75, 1.5, 3, 6, . . .
To Find:Find the 12th term
Solution:
0.75, 1.5, 3, 6, . . .
First term =a = 0.75
Common difference = [tex]r = \frac{a_3}{a_2} =\frac{a_2}{a_1}=\frac{1.5}{0.75}=\frac{3}{1.5}=2[/tex]
nth term of G.P. = [tex]a_n=a r^{n-1}[/tex]
Where a = First term = 0.75
r = common difference = 2
Substitute n = 12
[tex]a_{12}= 0.75 (2)^{12-1}[/tex]
[tex]a_{12}= 0.75 (2)^{11}[/tex]
[tex]a_{12}= 1536[/tex]
Hence the 12th term in the geometric sequence. 0.75, 1.5, 3, 6, . . . is 1536.

One hundred employees of a company are asked how they get to work and whether they work full time or part time. The table below shows the results. If one of the 100 employees is randomly selected, find the probability of getting someone who carpools or someone who works full time.
Full time Part time
Public Transportation 7 10
Bicycle 4 3
Drive alone 30 31
Carpool 6 9
The probability of getting someone who carpools or someone who works full time is 0.36.
Explanation:To find the probability of getting someone who carpools or someone who works full time, we need to add the probabilities of the two events.
The probability of getting someone who carpools is 6/100 and the probability of getting someone who works full time is 30/100.
So the probability of either event happening is (6/100) + (30/100) = 36/100 = 0.36.

In how many ways can the letters of the word BANANA be rearranged such that the new word does not begin with a B?
First arrange the words in order:
AAABNN
so there are 3 A's, 1 B and 2 N's.
If there were no constraints,
Number of permutations = (3+1+2)!/(3!1!2!)=6!/(6*1*2)=720/(6*2)=60
Number of words that begin with B is to take out the B, that leaves us with
AAANN => 3 A's and 2 N's
=> 5!/(3!2!) = 120/(6*2)=10
Therefore the number of words that do NOT begin with B is
60-10 = 50 ways

match each graph with its corresponding equation
The graphs match the equations as follows:
Graph A: (−x+3)^2 -2
Graph B: (x−2)^2+3
Graph C : −(x+2)^2 +3
Graph D : 2(x−2)^2 +3
Equation (−x+3)^2 -2:
This equation is in the form of a quadratic function, y=a(x−h) ^2+k, where (h ,k) is the vertex of the parabola.
The vertex of the parabola is at (3,1), which matches the vertex of Graph A.
The coefficient a is negative, which tells us that the parabola opens downward.
The constant term k is −2, which tells us that the minimum value of the parabola is −2.
Equation (x−2)^2+3 :
This equation is in the form of a quadratic function, y=a(x−h) ^2 +k, where (h, k) is the vertex of the parabola.
The vertex of the parabola is at (2,3), which matches the vertex of Graph B. The coefficient a is positive, which tells us that the parabola opens upward.
The constant term k is 3, which tells us that the minimum value of the parabola is 3.
Equation −(x+2)^2 +3:
This equation is in the form of a quadratic function, y=a(x−h) ^2 +k, where (h, k) is the vertex of the parabola.
The vertex of the parabola is at (−2,3), which matches the vertex of Graph C.The coefficient a is negative, which tells us that the parabola opens downward.
The constant term k is 3, which tells us that the maximum value of the parabola is 3.
Equation 2(x−2)^2 +3 :
This equation is in the form of a quadratic function, y=a(x−h) ^2 +k, where (h ,k) is the vertex of the parabola.
The vertex of the parabola is at (2,3), which matches the vertex of Graph D. The coefficient a is positive and multiplied by 2, which tells us that the parabola opens upward and is stretched vertically by a factor of 2.
The constant term k is 3, which tells us that the minimum value of the parabola is 3.
