Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0) 1 :3

Answers

Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Step-by-step explanation:

To find diameter, divide circumference by pi or 3.14

47.5/3.14 = 15.1273885

Round to nearest hundredth gives you 15.13

A shelf is 36 inches long. How many DVD’s can I place on it if each one is 5/8 inches thick?

Answers

we can find this by diving 36 by 5/8
We will use the keep, change, flip rule
So instead of 36 / 5/8
We will calculate as
36 * 8/5
We will first multiply 36 * 8 = 288
Now we have 288/8 = 36
This means 36 DVDs will fit on the shelf

You can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick. To determine the number of DVDs that can fit on a shelf, we need to divide the length of the shelf by the thickness of each DVD.

The shelf is 36 inches long, and each DVD is 5/8 inches thick.

Dividing the length of the shelf by the thickness of each DVD:

36 inches / (5/8) inches

To divide by a fraction, we multiply by its reciprocal:

36 inches * (8/5 inches)

Simplifying the multiplication:

288 inches / 5 inches

Now we can divide:

288 inches / 5 inches = 57.6

Therefore, you can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick.

Harold cut 1812 inches off a rope that was 60 inches long. How is the length of the remaining rope in inches written in decimal form

Answers

Answer:

0.42

Step-by-step explanation:

The computation of the length of the remaining rope in inches is shown below:

Length Remaining = Length - the piece he cut off

Length Remaining = 60 - 18

60 - 18 = 42

To turn 42 into a decimal, you have to divide by 100 ↓

42 ÷ 100 = 0.42

The length of rope remaining is 0.42 inches long

A company makes muesli which contains nuts and sultanas.

They drew a table.

                                     50                    

To Find :

complete the table

calculate and estimate for the mean

The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:

Number of Nuts Number of Packets Midpoint (x) fx

4-6 5 5 5 * 3 = 15

7-9 8 8 8 * 9 = 72

10 - 12 11 11 11 * 12 = 132

13 - 15 14 14 14 * 17 = 238

16 - 18 17 17 17 * 9 = 153

Total 50  610

b) To calculate an estimate for the mean, we use the formula:

Mean = Sum of (fx) / Total Number of Packets

Mean = 610 / 50

Mean ≈ 12.2

Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

Step-by-step explanation:

The correct factoring can be found by looking at the first exponent in the second set of parentheses.

The factorization of ...

  (a^3 -b^3)

is ...

  (a -b)(a^2 +ab +b^2)

__

Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...

  a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice
