Okay, so, start by rearranging the problem (because it’s multiplication, you can do that), you get

(sin^2(x)-cos^2(x))*cos(x)*sec(x) + cos^2(x)

cos and sec are inverses, so they cancel each other out leaving you with

sin^2(x)-cos^2(x)+cos^2(x)

The cos^2(x) cancel each other out leaving you with

sin^2(x)

Helppppppppppppppppppppppppp
Rasek [7]

Answer:

A  40

Step-by-step explanation:

We can find angle K

J + K + L = 180  The angles of a triangle add to 180

50 + K + 90 =180

140 +K = 180

Subtract 140 from each side

140-140 + K = 180-140

K = 40

Since the triangles are congruent

J = P

K = N

L = M

We want to find N

K = N = 40

K = N

Rina8888 [55]

Answer:

He will expend 35 tickets for 7 rides. 3 tickets are left.

Step-by-step explanation:

Giving the following information:

Number of tickets= 38

Tickets per ride= 5

<u>To calculate the number of rides he can make, we need to use the following formula:</u>

Number of rides= number of tickets / tickets per ride

Number of rides= 38/5

Number of rides= 7.6 = 7 rides

He will expend 35 tickets for 7 rides. 3 tickets are left.

They charge $5 per ticket for a child and $12 per ticket for an adult they sell a total of 342 tickets and make a total of $2250
Olenka [21]

Answer: the number of children tickets sold 265

the number of adult tickets sold 77

Step-by-step explanation:

Let x represent the number of children tickets sold.

Let y represent the number of adult tickets sold.

They charge $5 per ticket for a child and $12 per ticket for an adult. They were sold for a total of $2250. This means that

5x + 12y = 2250 - - - - - - - - - -1

The total number of tickets sold is 342. This means that

x + y = 342

Substituting x = 342 - y into equation 1, it becomes

5(342 - y) + 12y = 2250

1710 - 5y + 12y = 2250

- 5y + 12y = 2250 - 1710

7y = 540

y = 540/7 = 77

x = 342 - y = 342 - 77

x = 265

Hello, I need this to be answered asap, it's attached and I also have more questions too.
Angelina_Jolie [31]

Answer:

2.33 x 3.26 = 6

32.13 x 2.26=64

523.1 x 9.71=5,230

2561/20.36=128.5

7.6 x 3.89=32

38.89 x 52.25=2028

1826/19.51=91.3

201.21 x 65.63=13,266

Step-by-step explanation: Again, going by what you said, 2.33 would round to 2. So, on the paper attached, I rounded all the numbers to the nearest whole number and then I multipled them. To clarify, if the answers need to be rounded to the nearest whole number as well, then 91.3 would be 91 instead and 128.5 would be 129 instead
