Answers

Answer 1

Answer:

cos 30

Step-by-step explanation:

cos 30 + sin 60 / 1+ sin 30 + cos 60

= root3 / 2 + root3/2 / 1 + 1/2 + 1/2

= root 6/2 by 4/2

= root 6/4

Bob order 151/2 pound of cherrys fron the farm,this year they want to order 1 1/4 more pound but then 2/5 of the order they want blue berrys what is the percent

Answers

Answer:

Percentage of cherries    = 60 %

Percentage of berries  = 40 %

Step-by-step explanation:

He orders  15 1/2 pounds every year.

He wants more=  1 1/4 pounds

So the total pounds = 15 1/2 + 1 1/4

                                 = 15 + 1 + 1/2 + 1/4

                                 = 16 + (2+1)/4

                                  =   16 + 3/4

                                  = 16 3/4 pounds

Out of 16  3/4 pounds they want 2/5 part to be of blue berries.

So blue berries = 16 3/4 * ( 2/5)

                          = 67/4 * ( 2/5)

                            = 67/10 = 6 7/10 pounds

Amount of cherries= 16  3/4- 6 7/10

                                 = 10 3/4- 7/10

                                  = 10 (15- 14)/20

                                   = 10 1/20 pounds

Percentage of cherries = Amount of cherries/ Total amount * 100

                                      = 201/20 / 67/4 *100

                                         = 201/20 * 4/67 *100

                                         = 201/335 *100

                                          = 60 %

Percentage of berries = 100- 60 = 40 %

Find the length of AC, correct to 2 decimal places.

Answers

Hello!

This is a question relating trigonometry to unknown sides.

Here we can use the law of sines, which state that if a triangle is a right triangle, the ratio between a side and the sin of its opposite angle will be equal to any other ratio of the same type.

This means that we can set up this equation.

[tex]\frac{17}{sin(90)}=\frac{AC}{sin(38)}[/tex]

[tex]AC=17sin(38)[/tex]

Be sure to be on degrees if you're on a calculator.

2x - 42 = 94

Solve for x

Answers

Answer:

x = 68

Step-by-step explanation:

2x - 42 = 94

Use inverse operations to add 42 to both sides of the equation.

2x - 42 + 42 = 94 + 42

Simplify this to-

2x = 136

Now divide 2x and 136 by two for-

2x/2 = 136/2

Simplify.

x = 68

The answer, then, is x = 68.

Michael breeds chickens and ducks.

Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532.
How much does a chicken cost, and how much does a duck cost?
A chicken costs $_____ and a duck costs $_____.

Answers

Answer:

Chicken:$8   Ducks:$5

Step-by-step explanation:

Let's assume

Chickens= c

Ducks=d

50c + 30d = 550 (divide this by 10)--- 5c+3d=55

44c + 36d = 532 (divide this by 4)--- 11c+9d=133

Solving simultaneously:

5c + 3d = 55 (x9)

11c + 9d = 133 (x3)

45c + 27d = 495

33c + 27d = 399

By subtraction we get:

(45c-33c+27d-27d)= 96

12c = 96

Chicken = $ 8 (96/12)

Ducks: 50(8)+ 30d = 550

30d = 150

Ducks = $5 (150/30)

Answers

Answer:

Total hair cut off  = [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

Given - Ameen went to the salon and had [tex]\frac{3}{8}[/tex] of an inch of hair cut off. The next day she went back and asked for another [tex]\frac{1}{2}[/tex] of an inch to be cut off.

To find - How much hair did she have cut off in all?

Proof -

Given that,

Firstly,

She cut off her hair = [tex]\frac{3}{8}[/tex]

Then,

She cut off her hair = [tex]\frac{1}{2}[/tex]

So,

Total hair cut off = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{2}[/tex]

                           = [tex]\frac{3 + 4}{8}[/tex] = [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

Your goal is to fill a right circular cylinder shaped bucket with water. The bucket has a radius of 6 inches and a height of 12 inches. If you use a right circular cone with a 3 inch radius and a 4 inch height, how many scoops of water will it take to fill the bucket ?

Answers

Answer:

36

Step-by-step explanation:

to answer this question :

determine the volume of the cylinder and the cone. Divide the volume of the cylinder by the volume of the cone

Volume of a cylinder = nr^2h

n = 22/7

r = radius = 6

h = height = 12

(22/7) x (6^2) x (12)  = 1357.71 in^3

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius = 3

h = height =

4

(1/3) x (22/7) x (3^2) x (4) = 37.71

1357.71 / 37.71 = 36 times

hey i just need an answer and possibly a step by step thanks !!!

Answers

Answer: 1517.54

Step-by-step explanation:

So we can divide solving this question into two parts: the 2% compound interest and the 5% compound interest.

We know that the compound interest equations is A = P(1+r/n)^nt where:

A is final amount

P is principal (initial) amount

r is interest rate

n is number times interest compounded

t is number of time periods

Given this, in the 2% compound we know:

A = ?

P = 1200

r = 2%

n = 1 (because it didn't say how many times compounded so we assume 1)

t = 2

This becomes:

A = 1200 (1 + (0.02/1))^ 1 * 2

A = 1248.48

Because we switching to 5% from 2%, we can assume that the final amount from the 2% will be the initial amount in the 5%. Thus:

A = ?

P = 1248.48

r = 5%

n = 1

t = 4 (because there were 6 years in total and we used 2 years for 2%)

This becomes:

A = 1248.48 (1 + (0.05/1))^ 1 * 4

A = 1517.54

a rectangular room measuring 5.75m by 6.5 in to be covered by whole square tiles,
Calculate the size of each tile and the number of tiles required.
(3mks)

Answers

Answer:

Below.

Step-by-step explanation:

The dimensions are  5.75m * 6.5 m

= 575cm * 650 cm.

Finding the GCF:

575 = 5 * 5 * 23

650 = 5 * 5 * 26

- so t he Greatest Common Factor of these 2 is 25cm.

575 / 25 = 23

650 / 25 = 26.

So we need 23 tiles along the width of the room and the length will have 26 tiles.

Each tile with be 25cm * 25 cm. in size and the number of tiles = 23*26

= 598.

15x  + 8y = 263.25  -------------(I)

Cost of 20 people's admission and 13 rental tubes is $ 358

20x + 13y = 358  ------------(II)

(I) * 13        195x + 104y = 3422.25
