Answer:

a) sine
b) 9.8 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA helps you remember the definitions of the trig functions. In particular, the function that involves the Opposite side and the Hypotenuse is the Sine function:

... Sin = Opposite/Hypotenuse

In this problem that means ...

... sin(55°) = x/(12 ft)

Multiplying by 12 ft, we have ...

... (12 ft)·sin(55°) = x ≈ 9.82982 ft ≈ 9.8 ft

Answer:

x=24

Step-by-step explanation:

8x-13 = 7x+11; (because it's a rectangle)

5. You are making your weekly mean plans and are working with the following constraints: It costs $8 to go out to dinner. It cos

Goshia [24]

Let

x-------> the number of dinner

y-------> the number of lunch

we know that

$8x+5y \leq 42$ -------> equation A

$x=y$ ------> equation B

Substitute equation B in equation A

$8[y]+5y \leq 42$

$13y \leq 42$

$y \leq 42/13$

$y \leq 3.23$

the greatest number of lunch is $y=3$

$x=y$

Hence

the greatest number of dinner is $x=3$

therefore

the greatest number of meals is

$x+y=3+3=6$

<u>the answer is</u>

$6$

kondaur [170]

Answer:

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately 0.65 ft

Step-by-step explanation:

Pam's picture frame : Square with area of 3 sq. foot

Meg’s picture frame is a circle with a radius, r of 1 foot.

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately feet.

Let's calculate circumference of Meg's picture frame:

Circumference c, = 2πr

r = 1 ft

c = 2 * 3.14 *1 = 6.28 ft

Now calculate Perimeter of Pam's picture frame:

A is area of square and s is the side

A = s²

s² = 3

s = √3

Permeter of square = 4s

= 4√3 = 6.93ft

Now in order to find circumference of Meg’s picture frame is the perimeter of Pam’s picture frame, we have to find their difference.

Permimeter of square frame - Circumference of circle frame = 6.93 - 6.28 = 0.65
