Answer:
Step-by-step explanation:
First we start off by rounding that number to the nearest ten, not tenTH. This rounding would lead to 180$. Now comes the percent part. Here i use the percent equation, which is ____ is ____% of _____. our percent is 10%, and our whole goes at the end, 180$. The part( or the tax), becomes x, and now we translate. Is means = and of means times. so x=.10(180), and x will equal 18
so the tip will be around 18 dollars

Angles and Lines
The figure attached below has been completed with the angle y to support the calculations to come.
The sum of the interior angles of a rectangle is 180°. Applying on triangle PQR:
30 + 4x + 2 + y = 180
Simplifying:
32 + 4x + y = 180
Solving for y:
y = 180 - 32 - 4x
y = 148 - 4x
Angles y and 8 + 6x are a linear pair, i.e. their sum is 180°, thus:
y + 8 + 6x = 180
Substituting y from the equation above:
148 - 4x + 8 + 6x = 180
Simplifying:
156 + 2x = 180
Dividing by 2:
78 + x = 90
Subtracting 78:
x = 90 - 78
x = 12
Bradley Wiggins cycles 2.5km on a warm up. If the diameter of Bradley's bike wheel is 68cm, how many times (to the nearest whole rotation) will Bradley's bike wheel have rotated on this journey?
Answer:
1171 rotations
Step-by-step explanation:
Given that:
Distance cycled = 2.5km
Diameter of bike wheel, d = 68cm = 0.68m
We obtain the Circumference of the bike wheel:
Circumference, C = πd
C = 3.14 * 0.68
C = 2.1352 m
The number of rotations Bradley's wheel will make will be :
Total distance cycled / Circumference
= (2.5 *1000)m / 2.1352m
= 2500 / 2.1352
= 1170.8505
= 1171 rotations
Triangle ABC is similar to triangle DEF
Answer:
A my dude. good luck!!!!!
Answer:
A
Step-by-step explanation:
AC = 5
DF = 15
5 x 3 = 15
BC = 3
EF = 9
3 x 3 = 9
Do you see the pattern? So as you can see the difference between Triangle ABC and DEF is the multiply/divide 3 so if you want to find DE then you should set it up as:
[tex]\frac{4}{3}[/tex] = [tex]\frac{DE}{9}[/tex] and to check if its right if you solve it you get [tex]\frac{4}{3}[/tex] = [tex]\frac{12}{9}[/tex]
and as you see [tex]\frac{12}{9}[/tex] and [tex]\frac{4}{3}[/tex] are literally the same thing just you need to simplify [tex]\frac{12}{9}[/tex]

Answer:
28 8/21
Step-by-step explanation:
18 5/7 + 9 2/3 (hint: remember you have to turn them into common denominators)
so ther least common denominator would be 21 so...
18 15/21 + 9 14/21
then add it together
28 8/21
Answer:
I got 28 8/21. There's a picture of how I did it.
Step-by-step explanation:
I used a method called the butterfly method. I did 18 + 9 which equals 27. Then I did 5/7 + 2/3 and got 29/21, and divided the fraction and got 28 8/21.

The hospital has found that if a patient is being visited on average at least 8.4 times per day, they can give the same patient care with 3 less nurse visits per day. How many nurse visits per day can the hospital reduce for these 13 patients?
Answer:
6
Step-by-step explanation:
the number of patients that get visted 8.4 times is 1 and another 1 at 8.3 add those up and mutiply by the 3 less nurses visits you get 6
Number of nurse hours the hospital can reduce is 6.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Number of patients visited on average at least 8.4 times per day = 2 patients
Now for each of the 2 patients the hospital can reduce 3 nurse visits.
Thus,
Number of nurse hours the hospital can reduce = 3 x 2
⇒ Number of nurse hours the hospital can reduce = 6 hours
Thus, Number of nurse hours the hospital can reduce is 6.

There is a 8% sales tax. After the tax, a 15% tip is
added.
What is the total after tax and tip?
Answer:
24.84$

You multiply 20 by 0.08 which equals 1.6
then you add 20 + 1.6 which equals 21.6
then you multiply 21.6 by 0.15 which equals 3.24
24.84

Using the normal distribution, the mean of T is of 30 seconds.
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
The mean of T is 10 seconds
A normal distribution has two parameters: Mean and standard deviation .
The given parameters are the mean completion time of each step, μ = 10 seconds
The standard deviation, σ = 5 seconds.
For the total completion, there are 3 instances, hence ,n = 3(10)
Thus, the mean of T is of 30 seconds.

Diego is preparing brownies and cookies for a bake sale. He would like to make equal-size bags for selling all of the 48 brownies and 64 cookies that he has. What is the largest number of combination bags that Diego can make with no left over? Explain how you know this is the largest possible number of bags?
Answer:
16 bags.
Step-by-step explanation:
From the question, we have:
48 brownies and 64 cookies that he has
Hence, we solve this question using Greatest common factor method.
The first step would be to find the factors of 48 and 64. We would then pick the Greatest (largest factor) common to both.
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 64 are: 1, 2, 4, 8, 16, 32, 64
Then the greatest common factor is 16.
Therefore, the largest number of combination bags that Diego can make with no left over is 16 bags

Find the coordinates of the orthocenter of a triangle with the vertices (0,0), (8,2), (2,8) at each set of points on a coordinate plane?
Answer:
coordinates of the orthocenter = (16/5, 16/5)
Step-by-step explanation:
I have drawn a diagram showing this triangle with the vertices. I have also drawn altitude from B perpendicular to AC at point E.
I have also drawn altitude from from A perpendicular to BC at point D.
Now, we will find the slope of AC from the line slope equation; (y - y1) = m(x - x1)
m = (y - y1)/(x - x1)
Our coordinates are; A(0,0), B(8,2), C(2,8).
Thus;
Slope of AC; m = (8 - 0)/(2 - 0)
m = 4
Since BE is perpendicular to AC, slope of BE = -1/slope of AC = -1/4
Thus, equation of BE is;
(y - 2) = -¼(x - 8)
Multiply through by 4 to get;
4y - 8 = -x + 8
x + 4y = 16
Slope of BC is; m = (8 - 2)/(2 - 8) = 6/-6 = -1
AD is perpendicular to BC, thus slope of AD = -1/-1 = 1
Equation of AD is;
(y - 0) = 1(x - 0)
y = x
Putting x for y in equation of BE, we have;
x + 4x = 16
5x = 16
x = 16/5
Since y = x in equation AD, then y = 16/5
coordinates of the orthocenter = (16/5, 16/5)
