Answer 1

So sin in math means:

In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.

Con in math means:

In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.

in this case it has to be a sin. So its either A, or B.

Jenny and Kath hire the canal boat for 14 days. They share the hire cost of £1785.00 in the ratio 2:3. Work out the smaller share.

Answers

Answer:

£714.00

Step-by-step explanation:

The first step is to set up expresssions for the two shares:

Let  x = the amount of one share.  The other share is 1785 - x.  You don't have to worry about which is smaller--that part will work out automatically!

The two shares are in the ratio of 2:3, so set up the proportion

[tex]\frac{x}{1785-x}=\frac{2}{3}[/tex]

Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.

Solve the proportion for  x  by "cross multiplying" -- use the Means-Extremes Property of proportions.

[tex](3)(x)=(2)(1785-x)\\3x=3570-2x\\5x=3570\\x=714[/tex]

So one share is £714£ and the other is £1785 - £714 = £1071.

The smaller share is £714.

The midpoint of AB is M (-2,0) . If the coordinates of A are (1,-7), what are the coordinates of B

Answers

Answer:

Step-by-step explanation:

Hope this helps u!!

Answer:

B (- 5, 7 )

Step-by-step explanation:

Using the midpoint formula, then equate x and y coordinates

let coordinates of B = (x, y ) , then

[tex]\frac{x+1}{2}[/tex] = - 2 ( multiply both sides by 2 )

x + 1 = - 4 ( subtract 1 from both sides )

x = - 5

[tex]\frac{y-7}{2}[/tex] = 0

y - 7 = 0 ( add 7 to both sides )

y = 7

Coordinates of B = (- 5, 7 )

Step-by-step explanation:

6² + 8² = x²

36 + 64 = x

36 + 64 = 100

√100 = 10

Answer:

6) 1/2 + 1/2 + 1/2 + 1/2 = 4/2 = 2 inches.

7)  5/8 + 5/8 + 5/8 = 15/8 = 1 7/8 inches.

8)  We've added the 1/2-inch crystals together and the 5/8-inch crystals together.  Adding together the 3/4-inch crystals we have:

3/4 + 3/4 + 3/4 = 9/4 = 2 1/4 inches

Adding together the 3/8-inch crystals we have:

3/8 + 3/8 + 3/8 = 9/8 = 1 1/8 inches.

Totaling what we have:

2 + 1 7/8 + 2 1/4 + 1 1/8

= 2 + 1 7/8 + 2 2/8 + 1 1/8 (you can only add fractions if they have common denominators)

= 6 + 7/8 + 2/8 + 1/8 (add the whole numbers together)

= 6 10/8 = 6 + 1 2/8 = 7 2/8 = 7 1/4 inches.

9)  To find an average, we add all of the data points together and divide by the number of data points.  We added them in number 8.  Now we divide this total, 7 1/4, by 13:

7 1/4 ÷ 13 = 29/4 ÷ 13/1 = 29/4 × 1/13 = 29/52 inches average for the crystals.

Tulsa has 4 times as many mangoes as Julie. Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie . How many many mangoes Tulsa had at first

Answers

Answer:

24

Step-by-step explanation:

Let the number of mangoes owned by Tulsa be T and that by Julie be J

If Tulsa has 4 times as many mangoes as Julie then

T = 4J

Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie

T + 6 = 5J

Solve both equations simultaneously by substitution

4J + 6 = 5J

Collect like terms

6 = 5J- 4J

J = 6

Since

T = 4J

T = 4 * 6

= 24

Hence Tulsa had 24 mangoes at first

By substituting the values for a, r and n we can find the desired term that we want. r=7525, cancelling out the common factors, we get r=3. As we want the 6th term to find, substituting n=6,r=3&a=25 in the above equation, we get (25)(3)6−1. Simplifying this expression, we get 6075.

450/20000*100%

450/200%

2.25%

first convert 450 g to kg = 0.45 kg

Now 0.45 kg as a. percentage of 20 kg = 0.45/20×100= 2.25%

2 fifth of 6x = 2/5 * 6x = 12x/5

2 fifth of 6 = 2/5 * 6 = 12/5

A two-factor between-subjects design is evaluated. The F-value for Factor A has df = 1, 40 and the F-value for Factor B has df = 3, 40. Based on this information, what are the df values for the A x B interaction?

Answers

Answer:

The df values for the A x B interaction are also 3,40

Step-by-step explanation:

The F-value for Factor A has df = 1, 40

The F-value for Factor B has df = 3, 40.

The df values for the A x B interaction are also 3,40

This is because the source of variation between columns has ( c- 1); rc(n-1) degrees of freedom and  the source of variation between  rows has (r-1); rc(n-1) degrees of freedom and the  source of variation of interaction

(between rows and columns)  has ( c-1) ( r-1); rc(n-1) degrees of freedom.

Therefore

Factor A:  ( c- 1); rc(n-1)    = 1,40

Factor B:    (r-1); rc(n-1)     = 3,40

Interaction : ( c-1) ( r-1); rc(n-1)   =  3*1,(40)= 3,40

where c refers to columns , r refers to rows and n refers to the total sample size.
