Angles 1 and 2 are complementary. If angle 1 = 35, then what is the measure of angle 2?

Answer:

to 1 decimal place,. (a) tan (3x + ... (i) 2cos 2x – 5sin 2x = 0 R cos(2x + λ) = 0 λ = 68.2 ⇒ 2x + 68.2 = 90 B1. 2x + λ = ... (16cos2x – 9)(cos2x – 1) = 0.

Step-by-step explanation:

-6+12=6

6+12[tex]\neq[/tex]6

Answer

False

Step-by-step explanation:

Start at 6 , and move 8 units to the left. Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

Answer:

1 theater

Step-by-step explanation:

Given

[tex]P<4.75[/tex] --- Popcorn

[tex]P < 8.00[/tex] --- Movie

See attachment for the table that shows ticket and popcorn prices at five movie theater chains

Required

The number of theaters that supports the given inequality

The given inequality can be combined to give:

[tex]P < 4.75\ and\ P<8.00[/tex]

From the table entries, only one theater supports this inequality.

Where

[tex]P = 4.25[/tex] --- Movie

[tex]P = 7.25[/tex]  --- Popcorn

Which gives:

[tex]4.25 < 4.75\ and\ 7.25<8.00[/tex]

Answer:

20%

Step-by-step explanation:

180 + 720 = 900 total people in town

180/900 or 180 ÷ 900 = 0.2 or 20%

Answer:

Step-by-step explanation:

3b+8c=50c

3b=50c-8c

3b=42c

b=14c

So there are 14 cookies in each box.

Answer:

14

Step-by-step explanation:

First, take away the 8 cookies that were not part of the 3 boxes.

(50 - 8 = 42)

Now we know that 3 boxes of cookies can hold 42 total cookies. However, we need to know how much cookies 1 box can hold. If the 42 cookies are divided evenly between the 3 boxes, our equation would look like this:

42/3 = 14

Therefore, the answer is 14 cookies in each box.

7.15 (two sig figs)

Step-by-step explanation:

There is a time limit dude, googling is a faster way

1. Area of rectangle

A = l*z

2. Find z

93 = 13*z

z ≈ 7.15

Answer:

7km

Step-by-step explanation:

The given figure is a rectangle

The formula to find area of rectangle is,

[tex]l \times b[/tex]

Here,

Length = 13km

Area = 91 km^2

Then breadth = 91/13

= 7 km

Answer:

12 times

Step-by-step explanation:

you have to count how many times that the number 8 comes up.

Answer:

9x

Step-by-step explanation:

Since all of them have the same variable you can add them up

1x+3x+5x=9x

Answer:

The value of b is either + 6 or -6

Step-by-step explanation:

Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x

mathematically, the discriminant can be calculated using the equation;

D = b^2 - 4ac

a represents the coefficient of x^2 which is 3

b represents the coefficient of x given as b

2 represents the last number

D is the discriminant = 12

So we have that;

12 = b^2 - 4(3)(2)

12 = b^2 - 24

b^2 = 24 + 12

b^2 = 36

b = √36

b = +6 or -6

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = [tex]\frac{18}{25}[/tex]

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

Answer:

1/12

Step-by-step explanation:

Multiply 1/2 x 1/6 = 1/12

Answer:

See explanation

Step-by-step explanation:

Recall that all the sides of the square are equal

Hence;

Area of a rectangle= l * b ------- equation 1

Perimeter of a rectangle = 2(l + b)----------equation 2

Area of the rectangle = 140 square centimeters

140 = lb

l = 140/b

Perimeter of the rectangle =  54 centimeters

substituting l = 140/b into equation 2

54 = 2(140/b + b)

Multiplying through by b

54b = 280 + 2b^2

Hence;

2b^2 - 54b + 280 = 0

Solving the quadratic equation

b=20 or b=7

substituting b=20 or b=7 into l = 140/b

l = 140/20 or l = 140/7

l = 7 or 20

THEREFORE;

b=20 cm or b=7 cm

l = 7cm or 20cm

Answer:

y = -28/5

Step-by-step explanation:

R = 7x +5y

35 = 7(9) + 5y

35 = 63 +5y

-5y= 63- 35

-5y/-5 = 28/-5

Y = -28/5

Answer:

Y = - [tex]\frac{28}{5}[/tex]

Step-by-step explanation:

Given

R = 7X + 5Y ← substitute X = 9, R = 35

35 = 7(9) + 5Y

35 = 63 + 5Y ( subtract 63 from both sides )

- 28 = 5Y ( divide both sides by 5 )

- [tex]\frac{28}{5}[/tex] = Y
