Answer:
In total I had to pay $ 82.42.
Step-by-step explanation:
Since I and my friends went to dinner and I decided to pay for everyone's meal, and the total bill came to $ 65.00, and I decided to give the waiter a 20% tip before tax and also had to pay 6.8% sales tax, for To determine how much did I have to pay in all, the following calculation should be performed:
65 + (65 x 0.2) + (65 x 0.068) = X
65 + 13 + 4.42 = X
78 + 4.42 = X
82.42 = X
Therefore, in total I had to pay $ 82.42.

What are m<1 and m<2? Please help me
Answer:
Your answer is B
Step-by-step explanation:
The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.
Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.
Sorry if this is confusing the book will have better explanations than I can give.

Answer:
13 and 32
Step-by-step explanation:
let one number be x
Then the other number is x + 19 , then
x + x + 19 = 45
2x + 19 = 45 ( subtract 19 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The 2 numbers are 13 and 13 + 19 = 32

A survey of Lakeview High School students found that 72% of the students had eaten breakfast that morning. If two students are chosen at random from a group of 100 students, what is the probability that at least one of them did not eat breakfast that morning?
Answer:
4.26 * 10^-12
Step-by-step explanation:
Usibg the binomial probability relation :
P(x =x) = nCx * p^x * q^(n-x)
Probability of success = probability of not eating = 1 - 0.72 = 0.28
p = 0.28
q = 1 - p = 0.72
Probability that atleast one out of 2 chosen did not eat breakfast :
P(x ≥ 1) = p(x = 1) + p(x = 2)
P(x ≥ 1) = (100C1 * 0.28^1 * 0.72^99) + (100C2 * 0.28^2 * 0.72^98)
= 4.26 * 10^-12

If a triangle has side lengths 7, 10, and 12, is it a right triangle??
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, [tex]a^2 + b^2 = c^2[/tex]
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, [tex]7^2 + b^2 = 12^2[/tex] or [tex]10^2 + b^2 = 12^2[/tex]
[tex]7^2 + b^2 = 12^2[/tex] ==> 49 + b^2 = 144 ==> b= [tex]\sqrt{95[/tex] ==> 9.746
b= 9.7, not 10.
[tex]10^2 + b^2 = 12^2[/tex] ==> 100 + b^2 = 144 ==> b = [tex]\sqrt{44[/tex] ==> 6.633
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!
Additional mathematics
Answer:
I don't know what you want me to answer but this is the definition=Additional Mathematics is a qualification in mathematics, commonly taken by students in high-school (or GCSE exam takers in United Kingdom). It is applied to a range of problems set out in a different format and wider content to the standard Mathematics at the same level.

Identify the initial conditions y(0) and y'(0) for the vertical motion of an object, if the object is thrown downward at a velocity of 6 m/s from a height of 30m. (take the origin to be on the ground)
Answer:
The right solution is "y(0) = 30 m" and "y'(0) = -6 m/s²".
Step-by-step explanation:
Given,
Velocity,
u = -6 m/s
Height,
h = 30 m
Now,
By using shifting of origin, we get
⇒ [tex](y-30)=-6t+\frac{1}{2}(-9.8)t^2[/tex]
[tex]y-30=-6t-4.9t^2[/tex]
[tex]y=30-6t-4.9t^2[/tex]
hence,
The value of y(0) is:
y(0) = [tex]30-0-0[/tex]
= [tex]30 \ m[/tex]
The value of y'(0) is:
y'(t) = [tex]-6-9.8t[/tex]
y'(0) = [tex]-6 \ m/s^2[/tex]

The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation
Time (days):3,4,5,6 cost($):75,100,125,150
Answer:
The rate of change is 25 and that means the cost per day is $25
Step-by-step explanation:
Since we have a constant rate of change, we can select any two points, apply the slope formula
The slope formula is;
m = (y2-y1)/(x2-x1)
(x1,y1) = (3,75)
(x2,y2) = (6,150)
m = (150-75)/(6-3) = 75/3 = 25
What the rate of change means here is that the cost per day is $25
