Answer:
Total time = 19 minutes.
Step-by-step explanation:
Given the following data;
Time to shower = 720 seconds
Time to eat breakfast = 420 seconds
To find the total time in minutes;
Total time = 720 + 420
Total time = 1140 seconds
We know that 60 seconds equals a minute.
Total time = 1140/60
Total time = 19 minutes.
Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.

Answer:
Step-by-step explanation:
When you distribute a positive sign to a parentheses, you essentially change nothing. So, you can drop all of the parentheses for this entire equation. Now combine like terms.

find the area of a circle with a radius of 2cm
Answer:
12.566
12.6 (simplified to the tenths)
12.57(simplified to the hundredths)
Step-by-step explanation:
The diameter of a circle is always double of the radius
π is always ≈ 3.14
π * 2^2 = π * 4 ≈ 12.566

27/8 or 3 3/8 or 3.375
Answer:
27/8 or 3 3/8
Step-by-step explanation:
So you would convert both fractions into improper numbers.
So 2 1/4 would be 9/4
And 1 1/2 would be 3/2
Then you would multiply them both. Your answer would be 27/8
Missy has 4 times as many trading cards as her friends Ashe and Caleb combined. Ashe
has 17 cards. Missy has 156 cards. How many trading cards does Caleb have?
Answer:
22
Step-by-step explanation:
Missy has 156 cards in total. Since we know she has 4 times as many as them, we divide 156 by 4
156/4= 39
Ashe has 17 cards and we still don't know how many Caleb has. Since we know that they have 39 cards together, we need to subtract Ashe's cards to find how many Caleb has
39-17=22
Let's check our work
Caleb has 22 cards
Ashe has 17 cards
Together they have 39
Which is 4 times less than how many cards Missy has
Missy has 156 cards
We are correct!

I need help on this one.
Answer:
1. 65°
2. 115°
Step-by-step explanation:
1 is a linear pair
2 u just do 180 - 65 =___
that is ur answer
Answer:1. 65 2. 115
Step-by-step explanation:
the opposite side is 65 so is the one directly across it because it’s linear
A straight line is 180 so you subtract 65 from 180 to get 115

The graph represents the relationship between x (the number of owls fed) and y (the number of rev dollars spent). What is the amount of money that will be spent to feed 10 owls? pls hurry
Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.
Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.
The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.
Hope this helps!

What is the slope of the line shown below?
Answer:
Option D
Step-by-step explanation:
We are given the two points of (5, 11) and (-5, -1).
Use the slope formula.
[tex]m=\frac{rise}{run}=\frac{-1-11}{-5-5} =\frac{-12}{-10} =\boxed{\frac{6}{5}}[/tex]
The correct option should be Option D.
Hope this helps you.
Questions Below. Would Appreciate Help!
Answer:
The function that could be the function described is;
[tex]f(x) = -10 \cdot cos \left (\dfrac{2 \cdot \pi }{3} \cdot x \right ) + 10[/tex]
Step-by-step explanation:
The given parameters of the cosine function are;
The period of the cosine function = 3
The maximum value of the cosine function = 20
The minimum value of the cosine function = 0
The general form of the cosine function is presented as follows;
y = A·cos(ω·x - ∅) + k
Where;
[tex]\left | A \right |[/tex] = The amplitude = Constant
The period, T = 2·π/ω
The phase shift, = ∅/ω
k = The vertical translation = Constant
Therefore, by comparison, we have;
T = 3 = 2·π/ω
∴ ω = 2·π/3
The range of value of the cosine of an angle are;
-1 ≤ cos(θ) ≤ 1
Therefore, when A = 10, cos(ω·x - ∅) = 1 (maximum value of cos(θ)) and k = 10, we have;
y = A × cos(ω·x - ∅) + k
y = 10 × 1 + 10 = 20 = The maximum value of the function
Similarly, when A = 10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, we get;
y = 10 × -1 + 10 = 0 = The minimum value of the function
Given that the function is a reflection of the parent function, we can have;
A = -10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, to get;
y = -10 × -1 + 10 = 20 = The maximum value of the function
Similarly, for cos(ω·x - ∅) = 1 we get;
y = -10 × 1 + 10 = 0 = The minimum value of the function
Therefore, the likely values of the function are therefore;
A = -10, k = 10
The function is therefore presented as follows;
y = -10 × cos(2·π/3·x) + 10
