Answer:

well 6/20 has more absolute value than 7/30

Step-by-step explanation:

also 7/30 is closer to zero

Comparison of 30% has more absolute value than 23.3%

Percentage is defined as ratio expressed as a fraction of 100.

Let x = 6 broken bulbs out of 20

y =  7 broken bulbs out of 30

x = 6/20

x = 0.3

There are 30% bulbs broken out of 20

y = 7/30

y = 0.233

There are 23.3% bulbs broken out of 20

Hence, 30% has more absolute value than 23.3%

The correct answer is option (D).

A triangle is a polygon with 3 sides.

Given the triangles ΔABE and ΔACD.

The triangle ΔABE is a smaller-scaled replica of the triangle ΔACD, therefore, the triangles ΔABE and ΔACD are similar triangles.

Since the triangles are similar, the ratio of their corresponding sides is proportional.

Therefore,

BE/CD = AB/AC

Or, BE = CD· (AB/AC)

Hence, the correct answer is option (D).

Answer:

1/2.25

Step-by-step explanation:

let volume of P be x

Q will be 1.5x

R will be 150/100* 1.5x which is 2.25x

P/R = x/ 2.25x

= 1/2.25

Here we need to write the volume of sphere P as a fraction of the volume of sphere R.

We will get:

[tex]V_P = V_R/2.25[/tex]

The given information is:

From the first statement, we can write:

[tex]V_Q = (1.5)*V_P[/tex]

Where the 1.5 comes because the volume of sphere Q is 150% of the volume of sphere P.

From the second statement we can write:

[tex]V_R = (1.5)*V_Q[/tex]

We can rewrite this last one as:

[tex]V_Q = V_R/(1.5)[/tex]

Now we can replace this on the first equation to get:

[tex]V_R/(1.5) = (1.5)*V_P\\\\V_P =V_R/(1.5)^2 = V_R/2.25[/tex]

This is the equation we wanted, the volume of sphere P as a fraction of the volume of the sphere R.

y = x^2

The domain is the possible input values

X can be any value so the domain is all real values of x

Answer:

Domain is all real Numbers

Range is all numbers over 0 - (0, ∞ )

Step-by-step explanation:

One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from  

( − ∞ , ∞ )

For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.

in this situaltion we found that the vertex is at the the origin at (0,0)

therefore the range is (0, ∞ )

Step-by-step explanation:

Two tangents to a circle from the same external point are congruent.

There are 4 pairs of congruent tangents in the figure.

Answer:

  perpendicular line through a point on a line

Step-by-step explanation:

The circle centered at C seems intended to produce point D at the same distance as point B. That is, C is the midpoint of BD.

The circles centered at B and D with radius greater than BC seems intended to produce intersection points G and H. (It appears accidental that those points are also on circle C. As a rule, that would be difficult to do in one pass.)

So. points G and H are both equidistant from points B and D. A line between them will intersect point C at right angles to AB.

Segment GH is perpendicular to AB through point C (on AB).

Answer:

Perpendicular line through a point on a line

Step-by-step explanation:

Answer:

Using the given information from the graph, the x-intercept of the line is -1 and the y-intercept of the line is -4.

Step-by-step explanation:

For this problem, we are asked to find the x-intercept and the y-intercept of the line. The x-intercept represents the point where the line hits the x-axis. The y-intercept represents the point where the line hits the y-axis.

So, knowing this, we have the find the points where the line hits the x-axis and the point where the line hits the y-axis.

The line hits the x-axis at (-1,0). The line hits the y-axis at (0,-4)

So, the x-intercept of the line is -1 and the y-intercept of the line is -4.

Answer:

x = 5.25

Step-by-step explanation:

Answer:

A. f(t) = –16(t – 1)2 + 24

Step-by-step explanation:

The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game. The T-shirt starts at a height of 8 feet when it leaves the cannon and 1 second later reaches a maximum height of 24 feet before coming back down to a lucky winner. If the path of the T-shirt is represented by a parabola, which function could be used to represent the height of the T-shirt as a function of time, t, in seconds?

A. f(t) = –16(t – 1)² + 24

B. f(t) = –16(t + 1)² + 24

C. f(t) = –16(t – 1)² – 24

D. f(t) = –16(t + 1)² – 24

Answer: The path of the T-shirt is represented by a parabola. The general equation of a parabola is given by y = a(x - h)² + k with a vertex at (h, k).

The height of the t shirt is a function of the time. Given:

A. f(t) = –16(t – 1)² + 24

At time (t) = 0. Therefore:

f(0) = –16(0 – 1)² + 24  = -16 + 24 = 8 feet.

The vertex of the function is at (1, 24). This means at one second, the maximum height is 24 feet.

This is the correct option

B. f(t) = –16(t + 1)² + 24

At time (t) = 0. Therefore:

f(0) = –16(0 + 1)² + 24  = -16 + 24 = 8 feet.

The vertex of the function is at (-1, 24). This means at -1 second, the maximum height is 24 feet. The function is wrong since the time cnnot be negative

C. f(t) = –16(t – 1)² – 24

At time (t) = 0. Therefore:

f(0) = –16(0 – 1)² - 24  = -16 - 24 = -40 feet.

The vertex of the function is at (1, -24). This means at one second, the maximum height is -24 feet. This is not correct

D. f(t) = –16(t + 1)² – 24

At time (t) = 0. Therefore:

f(0) = –16(0 + 1)² + 24  = -16 - 24 = 8 feet.

The vertex of the function is at (-1, -24). This means at -1 second, the maximum height is -24 feet. This is not correct

These are the main data: the T-shirt starts at a height of 8 feet when it leaves the cannon and 1 second later reaches a maximum height of 24 feet

So, f(0) = 8 feet and f(1) = 24 feet

That means, that you can evaluate the functions at t = 0 and t = 1 to see which represents those two points, (0, 8) and (1, 24).

A: f(t) = –16(t – 1)^2 + 24

t = 0 => f(0) = - 16 (0 – 1) ^2 + 24 = -16 + 24 = 8 => This is Ok.

t =1 => f(1) = - 16 (1 – 1)^2 + 24 = 0 + 24 => This is Ok.

B: f(t) = –16(t + 1)^2 + 24

t = 0 => f(0) = -16 (0 + 1)^2 + 24 = - 16 + 24 = 8 => this is Ok

t = 1 => f(1) = -16 (1 + 1)^2 + 24 = -16(4) + 24 = - 64 + 24 = - 40 => Wrong

C: f(t) = –16(t – 1)^2 – 24

t = 0 => f(0) = -16 (0 – 1)^2 - 24 = -16 – 24 = - 40 => Wrong

D: f(t) = –16(t + 1)^2 – 24

t = 0 => f(0) = - 16 (0 + 1)^2 – 24 = -16 – 24 = - 40 => Wrong

Answer:

To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.

The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)

We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.

Step-by-step explanation:

The difference:

As we know each 15° represents 1 hr difference

91° 50' ÷ 15°= 6 in full number, so 6 hours difference

Since new point is towards West, the time difference would be negative:

12 PM - 6 hours = 6 AM
