A grandfather is ten times older than his granddaughter. He is also 54 years older than
her. How old is each of them?

Answers

Grandad = 60
Granddaughter = 6

Answer:

The present ages of the granddaughter and grandfather are 6 and 60 years.

Step-by-step explanation:

Let the present age of granddaughter be x years.

So, the present age of grandfather is 10x years.

According to the given condition, we have

10 x = 54 + x

9 x = 54

x = 6

10 x = 60

age of grandfather is 60

age of granddaughter is 6

Hence, the present age of granddaughter is 6 years and that of grandfather is 60 years.

There were 6 teams in a baseball tournament. Each team played against every other team exactly once during the tournament. A team earned 2 points for a win, 1 point for a tie, and 0 points for a loss. What was the total number of points earned by all 6 teams in the tournament?

Answers

Since there were 6 teams in a baseball tournament, and each team played against every other team exactly once during the tournament, and a team earned 2 points for a win, 1 point for a tie, and 0 points for a loss, to determine what was the total number of points earned by all 6 teams in the tournament, since a series of results have not been raised, the following table should be made:

Possible outcomes: 5 wins = 5 x 2 = 10 4 wins and 1 a draw = 4 x 2 + 1 = 9 4 wins and 1 loss = 4 x 2 = 8 3 wins and 2 draws = 3 x 2 + 2 x 1 = 8 3 wins, 1 draw and 1 loss = 3 x 2 + 1 = 7 3 wins and 2 losses = 3 x 2 = 6 2 wins and 3 draws = 2 x 2 + 3 x 1 = 7 2 wins, 2 draws and 1 loss = 2 x 2 + 2 x 1 = 6 2 wins, 1 draw and 2 losses = 2 x 2 + 1 = 5 2 wins and 3 losses = 2 x 2 = 4 1 win and 4 draws = 2 x 1 + 4 x 1 = 6 1 win, 3 draws and 1 loss = 2 x 1 + 3 x 1 = 5 1 win, 2 draws and 2 losses = 2 x 1 + 2 x 1 = 4 1 win, 1 draw and 3 losses = 2 x 1 + 1 x 1 = 3 1 win and 4 losses = 2 x 1 = 2 5 draws = 5 x 1 = 5 4 draws and 1 loss = 4 x 1 = 4 3 draws and 2 losses = 3 x 1 = 3 2 draws and 3 losses = 2 x 1 = 2 1 draw and 4 loss = 4 x 1 = 1 5 losses = 0

Find the slope given two points: (-9, -2) and (-5,0)

Answers

Answer:

1/7

Step-by-step explanation:

Consider the line passing through these two points.  The increase in x (run) from the first to the second is 14; the increase in y (rise) is 2.

Thus the slope of this line is m = rise/run = 2/14, or m = 1/7

Answer:

[tex]m = \frac{1}{2}[/tex]

Step-by-step explanation:

To find the slope using two given sets of coordinates, the following function can be used:

[tex]m = \frac{y2-y1}{x2 - x1}[/tex]

Where x1,y1 are one set of coordinates and x2,y2 are the other set:

[tex]m = \frac{0 - (-2)}{-5 - (-9)}\\[/tex]

[tex]m = \frac{0 + 2}{-5 + 9}[/tex]

[tex]m = \frac{2}{4}[/tex]

This can be simplified down to:

[tex]m = \frac{1}{2}[/tex]

Find n in terms of x

Answers

Answer:

n = x + 8

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

Then

[tex]3^{x}[/tex] × [tex]9^{4}[/tex] = [tex]3^{n}[/tex]

[tex]3^{x}[/tex] ×[tex](3^2)^{4}[/tex] = [tex]3^{n}[/tex]

[tex]3^{x}[/tex] × [tex]3^{8}[/tex] = [tex]3^{n}[/tex]

[tex]3^{x+8}[/tex] = [tex]3^{n}[/tex]

Since bases on both sides are equal, both 3, then equate exponents

n = x + 8

Jerry is building a model car. The picture shows one of the wheels for the car. The wheel has a diameter of 30 millimeters.
30 mm
Which is closest to the distance around the outside edge of the wheel?

Answers

We want to find the distance around the outside wheel of the car given that we know its diameter. We will see that this distance is 94.2mm

So the distance around the outside edge of the wheel will be equal to its circumference.

We do know that for a circle of diameter D the circumference is defined as:

C = pi*D

Where pi = 3.14

Here we do know that the diameter is 30 mm, then the circumference of the wheel will be:

C = 3.14*30mm = 94.2 mm

This is the distance around the outside edge of the wheel.
