When a child flying a kite has let out 60 meters of string, the string makes an angle of 60 degrees. How high is the kite?

Answers

Answer:

The height is: [tex]h = 51.96cm[/tex]

Step-by-step explanation:

Given

[tex]L = 60m[/tex]

[tex]\theta = 60[/tex]

Required

The height of the kite

See attachment for illustration.

To calculate height (h), we have:

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

This gives

[tex]\sin(60) = \frac{h}{60}[/tex]

Make h the subject

[tex]h = 60 * \sin(60)[/tex]

[tex]h = 60 * 0.8660[/tex]

[tex]h = 51.96cm[/tex]

Solve each by elimination
x+y =19
x - y = -7

Answers

x + y = 19
x - y = -7
Subtract both
2y = 26, y = 13
Plug into first equation
x + 13 = 19
x = 6

Solution: x = 6, y = 13

Answer:

x = 6

y = 13

Step-by-step explanation:

x + y = 19

x - y = -7

To eliminate x, subtract ther second equation from the first

2y = 26

y = 13

To eliminate y, add the equations

2x = 12

x = 6

A cuboid has a volume of 24 cm^3. What can its maximum surface area be, if its length, breadth, and height are integers?

Answers

Answer:

76 cm^2

Step-by-step explanation:

Volume of the cuboid = Length(l)×breadth(b)×Height (h)

Given that

A cuboid has a volume of 24 cm^3 and its length, breadth, and height are integers only.

prime factor of 24 = [tex]2^3\times3\times1[/tex]

24 = 2×3×2×2×1

24= 12×2×1

or 24= 6×4×1

Now, for Surface area to be maximum we have to take dimensions as

12,2,1

SA = 2(lb+lh+bh)

=2(12×2+12×1+2×1)

= 76 cm^2

Therefore, maximum area of the cuboid with diemensions, 12,2,1 = 76 unit

The product (-9 )x(-5) x(-6)x(-3) is positive whereas the product (-9)x(-5)x6 x(-3) is negative. Why?

Answers

Answer:

Answers below!

Step-by-step explanation:

-9 x -5 = 45

45 x - 6 = -270

-270 x -3 = 810

The answer is positive because a negative multiplied by a negative equals a positive number.

-9 x -5 = 45

45 x 6 = 270

270 x -3 = -810

This answer is negative because a negative multiplied by a positive  equals a negative number.

Answers

Answer:49

Step-by-step explanation:

Manchu has drawn a
rectangle with a base of
24 cm and an area of
336 cm². He cuts the
rectangle as shown to make two triangles.
What are the height and area of each
triangle?

Answers

Answer:

Height of each triangle: 14cm

Area of each triangle: 168cm²

Step-by-step explanation:

So we know that the base of the area is 24. Lets find the height.

336 ÷ 24 = 14

If he makes two triangles out of the rectangle that just means he cuts it in half.

To find the area of one triangle lets do:

336 ÷ 2 = 168

Let's double check our answer:

(14 × 24) ÷ 2 = 168
