if cosA=2/5, find the value of 4+4 tan^2A

Answers

Answer 1
The first equation is given to determine A.

cos A = 2/5
A = cos⁻¹(2/5) = 66.42°

Now that we know A, we use this value to the second equation.

4 + 4tan²A = 4 +24.996 4tan²(66.42°) = 24.996 ≈ 25

An amusement park sells child and adult tickets at a ratio of 8:1. On Saturday, they sold 147 more child tickets that adult tickets. How many tickets did the amusement park sell on Saturday?

Answers

Because the ratio is eight to one and 147 child tickets were sold, an easy way to solve the problem is through cross-multiplication: 8 over 1 times 147 over X. Using this equation, you'd divide 147, the number of child tickets, by 8, the child ticket ratio equivelant. By doing this, you'll find that the adult tickets sold on Saturday was approximately 18 (the answer comes out to a decimal, but for tickets you'd round to the nearest number).

What is the slope of the line?
y = -9/10x + -6
Question 8 options:
a) 6
b) 9/10
c) -6
d) -9/10

Answers

D) -9/10

because the slope is the number before the x
The slope-intercept form of the equation of a line is

y = mx + b

where m = slope, and b = y-intercept.

m, the slope, multiplies the variable x.

m = slope

In your case, you have -9/10 multiplying x, just like m is in the equation I wrote, so the slope is -9/10

The outside temperature was 73°f at 1.p.m and decreases at a rate of 1.5°f each hour. What expression can be used to determine the temperature h(h is the variable) hours after 1.p.m?

Answers

Your expression will be h = -1.5°x + 73°
Final answer:

The expression to represent the temperature 'h' hours after 1 p.m. given an initial temperature of 73°F and a decrease rate of 1.5°F per hour is 73 - 1.5h. This allows us to calculate the temperature at any given hour where 'h' is the number of hours after 1 p.m.

Explanation:

The problem involves dealing with linear equations, specifically those representing changes over time. In this situation, the temperature starts at 73°F at beginning of the time, i.e., at 1 pm and then decreases at a steady rate of 1.5°F per hour.

So, the decrease in temperature can be represented by 1.5h, where h is the number of hours elapsed since 1 p.m. As the temperature starts at 73°f, we subtract this decrease from the initial temperature. Therefore, the expression to determine the temperature after h hours is 73 - 1.5h.

This equation tells us that for each hour after 1 p.m., we simply subtract 1.5 from 73 and this would give the temperature at that time. For example, at 2 p.m., h equals 1, and the equation 73 - 1.5(1) gives us 71.5°F.

A catering company loses $110 as a result of delay. The 5 owners of the company must share the loss equally. Which integer represents the change in profit for each owner?

Answers

What you have to do first is you have 5 owners correct? Well you take anything they're sharing in this case it's delay/debt, so you divide $110 by 5 and you should get $22. This means that each owner would have to pay $22 to the delay.

The loss of each owner of the catering company is 22 dollars.

What is average?

Average is the sum of the total weights of each individual divided by the number of individuals.

Given that a catering company loses 110 dollars as a result of the delay and the company has 5 owners and they share the loss equally.

As the loss has been shared by the owners equally we have to divide the total loss occurred by the total no. of owners to obtain the amount of loss for each individual which is,

= 110/5 dollars.

The equation of the required line is: y=-x-1.

y=2x-1 is in slope intercept form. So the y-intercept = -1.

Given that the line intersects with y=2x-1 on the y-axis. It means the required line also has y-intercpt =b= -1.

Given that: The line is parallel to y=-x.

The slope of y=-x is -1. By comparing with y=mx+b.

Since the lines are parallel. So the required line will also have slope = m= -1.

So the equation of the required line is: y=mx+b or y = -1x + (-1) or y=-x-1.

Paul's family drove 377 mi to the beach averaging 58 ​ mi/h ​ on the way there. On the return trip home, they averaged 65 ​ mi/h ​ .

What was the total time Paul's family spent driving to and from the beach?

Answers

To get the answer you would do 377÷58 which would give you 6.5, that means that going to the beach is 6 hours and 30 minutes. For going home from the beach you would do 377÷65 which would give you 5.8 which means 5 hours and 48 minutes. Every 0.1 is 6 minutes while every 1.0 is an hour. To get to your final answer, you would add together 6 hours & 30 minutes with 5 hours & 48 minutes which would give you 12 hours and 18 minutes since there is 60 minutes in an hour, 48+30=78

Total time driving to and from beach: 12.3 hours; averaging 58 mph there, 65 mph returning home.

To find the total time Paul's family spent driving to and from the beach, we can calculate the time for each leg of the trip and then add them together.

1. Time taken for the trip to the beach:

[tex]\[ \text{Time}_1 = \frac{\text{Distance}_1}{\text{Speed}_1} \][/tex]

2. Time taken for the return trip:

[tex]\[ \text{Time}_2 = \frac{\text{Distance}_2}{\text{Speed}_2} \][/tex]

Given:

[tex]- Distance to the beach, \( \text{Distance}_1 = 377 \) miles\\- Speed to the beach, \( \text{Speed}_1 = 58 \) mph\\- Speed returning home, \( \text{Speed}_2 = 65 \) mph[/tex]

Let's calculate:

[tex]1. \[ \text{Time}_1 = \frac{377}{58} \][/tex]

[tex]2. \[ \text{Time}_2 = \frac{377}{65} \][/tex]

Now, let's compute:

[tex]\[ \text{Time}_1 = \frac{377}{58} \approx 6.5 \text{ hours} \]\[ \text{Time}_2 = \frac{377}{65} \approx 5.8 \text{ hours} \][/tex]

Finally, to find the total time spent driving to and from the beach, we add these times:

[tex]\[ \text{Total time} = \text{Time}_1 + \text{Time}_2 \]\[ \text{Total time} \approx 6.5 + 5.8 \]\[ \text{Total time} \approx 12.3 \text{ hours} \][/tex]

So, Paul's family spent approximately 12.3 hours driving to and from the beach.
