help me with this question

Answer:

1

Step-by-step explanation:

We know the value of cos 360° is always equal to 1.

Answer:

cos(360 + x) = cos x

Proof:

cosine identity:

cos(x + y) = cosxcosy - sinxsiny

or

cos(360 + x) = cos360cox - sin360sinx

but

cos360 = 1 and sin360 = 0

Therefore,

cos(360 + x) = cos x

Step-by-step explanation:

2.4 cm

Step-by-step explanation:

10/4 = 6/x

x = width of reduced picture

24 = 10x (cross multiplication)

24/10 = x

2.4 = x

The width of the reduced picture is 2.4 cm.

Answer:

27.42

Step-by-step explanation:

Answer:

2. el numero contante por que se suma o resta

Answer:

let, width be 'x'

perimeter of rectangle=2(length+width)

56=2(19+x)

56=38+2x

2x=56-38

x=18/2

x=9inches

so, the width of rectangle is 9 inches.

hope it helps.

Answer:

[tex] y = - 3 \\ \frac{4 + y}{4y} = \frac{4 + ( - 3)}{4( - 3)} = \frac{4 - 3}{ - 12} = \frac{ - 1}{12} [/tex]

Answer:

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

[tex]-2x+6=30-6x\\\\4x+6=30\\\\4x=24\\\\x=6[/tex]

1. add 6x to both sides

2. subtract 6 from both sides

3. divide both sides by 4

So, what you are supposed to find here is the surface area of this rectangular prism. So the answer is 52 units of the special reflective material is needed.

Since total surface area of a rectangular prism = 2(lb + bh + hl)

Where l = length of the ice block

b = width of the ice block

h = height of the ice block

Now total surface area for the given dimensions = 2(4×2 + 2×3 + 3×4)

= 2(8 + 6 + 12)

Answer:

q + d = 33  0.25q + 0.1d = 6 Option D

Step-by-step explanation:

The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:

q + d = 33

0.25q + 0.1d = 6

Martin has a combination of 33 quarters and dimes worth a total of $6.

Therefore,

q = number of quarters

d = number of dimes

0.1 dollars = 1 dime

0.25 dollars = 1 quarters

Therefore,

0.25q + 0.1d = 6

The quarters and dimes total 33. Therefore,

Therefore, the combined equation will be as follows:

q + d = 33

0.25q + 0.1d = 6

Answer: 50.24

Step-by-step explanation:

The equation to find the area of a circle is pi*r^2. First, r^2 is 4^2 which is 16.  Then times pi. Assuming pi in this case is 3.14, 3.14 times 16 is 50.24.
