Divide 6 feet 6 inches by 5

Answers

6 ft 6 in....
1 ft = 12 inches, so 6 ft = (12 * 6) = 72 inches...+ the other 6 inches = 78 inches

78 / 5 = 15.6 inches

Final answer:

To divide 6 feet 6 inches by 5, convert the length to inches, divide by 5, then convert back to feet and inches, resulting in 1 foot 3 inches per section.

Explanation:

To divide 6 feet 6 inches by 5, first convert the entire length to inches. Since there are 12 inches in 1 foot, 6 feet equals 72 inches (6 feet x 12 inches/foot). Adding the additional 6 inches gives us a total of 78 inches. Now, divide 78 inches by 5 to find the length of each section.

78 inches ÷ 5 = 15.6 inches per section.

To convert this back to feet and inches, remember that there are 12 inches in a foot. Therefore, 15 inches is 1 foot 3 inches, and the remaining 0.6 inches can be expressed as a fraction of an inch (0.6 x 12 = 7.2, which is approximately 7 inches). So, each section is 1 foot 3 inches.

K is the midpoint of line segment lm. the coordinates of k are (5, 12) and the coordinates of l are (2, 6), find the coordinates of m.

Answers

midpoint (K) is (5,12)

L = (2,6)
M = (x2,y2)

midpoint = (x1 + x2)/2 , (y1 + y2) / 2
m = (2 + x2) / 2 , (6 + y2)/2

(2 + x) / 2 = 5
2 + x = 5 * 2
2 + x = 10
x = 10 - 2
x = 8

(6 + y) / 2 = 12
6 + y = 12 * 2
6 + y = 24
y = 24 - 6
y = 18

Answers

The answer is A. 25.
Hope this helped!

Answer: The correct option is (A) 25.

Step-by-step explanation: We are given to find the value of x from the figure shown.

From the figure, we note that there are two parallel lines and a transversal.

Also, the angles with measurements (x + 40)° and (3x - 10)° are corresponding angles.

Since the measures of two corresponding angles are equal, so we must have

[tex](x+40)^\circ=(3x-10)^\circ\\\\\Rightarrow x+40=3x-10\\\\\Rightarrow 3x-x=40+10\\\\\Rightarrow 2x=50\\\\\Rightarrow x=\dfrac{50}{2}\\\\\Rightarrow x=25.[/tex]

Thus, the required value of x is 25.

Option (A) is CORRECT.

Use the pythagorean theorem to find the distance between x(7,11) and y(-1,5)..

Answers

so, if the legs are a and b and the hypothuse is c then
a²+b²=c²

the distance bewteen the points is the hyptohuse

the legs are the distances between th x and y values

so
(7,11) and (-1,5)
distances between the x values are 1 leg
that is from 7 and -1, a distance of 8 units

distances betweeen the y values are the other leg
that is from 11 to 5
that is 6 units

a²+b²=c²

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles.

A player wins a large prize for drawing a gold marble and a small prize for drawing a silver marble. There is no prize for drawing a red marble.

At the start of the game, the probability of winning a large prize is 0.05 and the probability of winning a small prize is 0.25.

1. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize?

2. If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize?

3. How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?

Answers

5 gold marbles,
25 silver marbles, and
70 red marbles.
------------------------------

100 total marbles

large prize: drawing a gold marble
small prize: drawing a silver marble.

At the start of the game,

probability of winning a large prize = positive outcoumes / total possible outcomes = 5 gold marbles / 100 total marbles = 0.05

probability of winning a small prize = positive outcomes / total possible outcomes = 25 silver marbles / 100 total marbles = 0.25.

1. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize?

Answer:

numer of silver marbles / number of total marbles = (25 -1 ) / (100 - 1) = 24 / 99 ≈ 0.24

2. If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize?

Answer:

First player: 0.25

Second player: 5 gold marbles / ( 100 - 1) total marbles = 5 /99 ≈ 0.0505

Third player: 5 gold marbles / (99 - 1) total marbles = 5 / 98 ≈ 0.051

Fourth player: 5 gold marbles / ( 98 - 1) total marbles = 5 / 97 ≈ 0.0515

So, the probability of winning a big prize increases as more balls different of gold marbles are extracted from the bag, and so, in this case, the fourth player has a greater chance to win a large prize.

3. How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?

Answer: All the players would have equal chance of winning a prize if the balls were replaced in the bag after each play.

A spherical scoop of ice cream is placed on top of a hollow ice cream cone. the scoop and cone have the same radius. the ice cream melts completely and it fills the cone to the top. how many times greater is the height of the cone than the radius of the cone?

Answers

The figure shown below illustrates the problem.

The volume of the empty cone is
V₁ = (1/3) π r²h

The volume of the sphere is
V₂ = (4/3) π r³

Because the melted ice cream completely fills the cone, therefore
V₁ = V₂
(1/3) π r² h = (4/3) π r³
Divide each side by (1/3) π r².
h = 4r

Answer:
The height of the cone is 4 times greater than the radius f the cone.

A system of linear equations includes the line that is created by the equation y=0.5x-1 and the line through the points (3, 1) and (–5, –7), shown below.

What is the solution to the system of equations?

a. (–6, –4)
b. (0, –1)
c. (0, –2)
d. (2, 0)

Answers

The answer is (2,0). If you graph the lines, it shows that the intersection occurs right there.

Answer: Solution is,

d. (2, 0)

Step-by-step explanation:

Since, the equation of line that passes through points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

[tex](y-y_1)=\frac{x_2-x_1}{y_2-y_1}(y-y_1)[/tex]

Thus, the equation of line through the points (3, 1) and (–5, –7) is,

[tex](y-1)=\frac{-7-1}{-5-3}(x-3)[/tex]

[tex](y-1)=\frac{-8}{-8}(x-3)[/tex]

[tex]y - 1 = x - 3[/tex]

[tex]\implies y = x - 2------(1)[/tex],

Equation of second line is,

[tex]y = 0.5x - 1 -----(2)[/tex],

By equation (1) and (2),

x - 2 = 0.5x - 1 ⇒ 0.5x = 1 ⇒ x = 2,

From equation (1),

We get, y = 0,

Hence, the solution of line (1) and (2) is (2,0).

Suppose the vertex of a parabola is in the first quadrant and the parabola opens upwards. What can be determined about the value of a and the discriminant?

Answers

A parabola is the graph of a quadratic function,

that is the graph of [tex]f(x)=a x^{2} +bx+c[/tex], where a is not 0.

from a, b and c we can derive the following informations about the shape of a parabola:

if a>0, the parabola opens upwards.
if a<0, the parabola opens downwards.

Consider the discriminant [tex]D= b^{2} -4ac[/tex]

If D>0, the parabola intersects the x-axis at 2 points.
If D=0, the parabola intersects the x-axis at 1 point.
If D<0, the parabola does not intersect the x axis.

"the vertex of a parabola is in the first quadrant and the parabola opens upwards."

the vertex is in the first quadrant means that the vertex is above the x-axis, and it opens upwards, so the parabola does not intersect the x-axis.

This means that:

Answer: a>0, the discriminant D<0

Final answer:

A parabola in the first quadrant opening upwards implies a positive 'a' value and a discriminant that, if not negative, yields real roots with positive values.

Explanation:

When a parabola has its vertex in the first quadrant and it opens upwards, we can determine specific values for a and the discriminant. The coefficient 'a' in the quadratic equation ax²+bx+c = 0 must be positive for the parabola to open upwards. Concerning the discriminant (calculated as b²-4ac), if the vertex is in the first quadrant, the parabola either does not intersect the x-axis at all (discriminant < 0), or it intersects the x-axis at one point (discriminant = 0) or two points (discriminant > 0) that both have positive x values.

The discriminant plays a key role in determining the nature of the roots of the quadratic equation. For quadratic equations constructed on physical data, they usually have real roots. Practical applications often deem the positive roots significant.

Joe the trainer has two solo workout plans that he offers his clients: Plan A and Plan

b. Joe trained his Monday clients for a total of 7 hours and his Tuesday clients for a total of 17 hours. How long does each of the workout plans last?

Answers

Let workout Plan A last a hours, and Plan B last b hours.

we are assuming personal training for each client.

i)
"On Monday there were 2 clients who did Plan A and 3 who did Plan"

the total time spent is : 2*a + 3*b =2a+3b

ii)
"On Tuesday there were 4 clients who did Plan A and 8 who did Plan B"

the total time spent was 4*a+8*b=4a+8b

iii) "Joe trained his Monday clients for a total of 7 hours"

so 2a+3b = 7

iv)

"Joe trained his Tuesday clients for a total of 17 hours"

so 4a+8b=17

v) thus we have the following system of equations:

2a+3b = 7
4a+8b=17

multiply the first equation by -2, and then add both equations, to eliminate a:

-4a-6b=-14
4a+8b=17
-------------------
2b=3, so b=3/2

2a+3b = 7
2a+3(3/2)=7
2a+9/2=7
multiply by 2:
4a+9=14
4a=5
a=5/4

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

In a circle, a tangent is always perpendicular to the radius of the circle. Therefore, in the given figure the triangle formed will be a right angled triangle.

Now, in a right angle triangle, using the Pythagoras theorem the relation between the different sides of the triangle can be written as,

AO² = AB² + OB²

(9.8)² = 5² + r²

96.04 = 25 + r²

r² = 96.04 - 25

r² = 71.04

r = √(71.04)

r = 8.4

Hence, the radius of the given circle is 8.4 units.

How to factor out the greatest common factor in a polynomial?

Answers

Hello,

To find something COMMON, we must at least have 2 things!

So , we can find the greatest common factor of 2 polynomials!

Final answer:

To factor out the GCF in a polynomial, identify the highest common factor, write it outside the parentheses, divide each term by the GCF, and write the quotients inside the parentheses.

Explanation:

To factor out the greatest common factor (GCF) in a polynomial, follow these steps:

First, identify the highest common factor that is present in each term of the polynomial.Write down this factor outside of a set of parentheses.Divide each term of the polynomial by the GCF, and place the resulting quotient inside the parentheses. This step can be seen as dividing both sides by the same factor to turn polynomial terms into integers, if that is easier to understand.Check your answer to see if it simplifies further and whether it is reasonable.

For example, for the polynomial 6x³ + 9x², the GCF is 3x2. Factoring out the GCF gives us:

3x²(2x + 3)

The products inside the parentheses are the result of dividing the original terms by the GCF. Remember, by finding the GCF, we simplify the algebra and may check the work by expanding the factored form back out to verify it equals the original polynomial.

y=-1, so the solution to the system of equations is the point:

Answer: 2x = 14

Step-by-step explanation:

Solving the equation us in elimination method,

x + y - 6 = 0...1

x - y - 8 = 0...2

From 1,

x+y = 6...3

x-y = 8...4

To eliminate y, we will add equation 3 and 4 since both the signs attached to y are different.

2x=6+8

2x = 14 (This will be the resulting equation)

To get the variables x, we will divide both sides of the resulting equation by 2

x = 14/2

x = 7

Substituting x = 7 into eqn 3
