Answer:
$12.42
Step-by-step explanation:
so the meal itself was $9.85
9.85*3.3% approximately equals $0.33
9.85+0.33=10.18
10.18*22% approximately equals $2.24
10.18+2.24=12.42
Therefore the answer is $12.42

Triangle ABC is translated according to the rule (x, y) → (x + 2, y – 8). If the coordinates of the pre-image of point B are
(4, –5), what are the coordinates of B'?
(2, 3)
(1, –9)
(–3, –4)
(6, –13)
Answer:
(6, -13)
Step-by-step explanation:
The rule is (x+2, y-8) so,
4+2=6
-5-8=-13
That would give you (6, -13)

A tank contains 50 liters of oil at time t = 4 hours. Oil is being pumped into the tank at a rate R(t) where R(t) is measured in liters per hour, and t is measured in hours. Selected values of R(t) are given in the table above. Using a right Riemann sum with three subintervals and data from the table, what is the approximation of the number of liters of oil that are in the tank at time t = 15 hours?
The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters.
How to estimate volume capacity by Riemann sumIn this question we must estimate the volume by Riemann sum, which consist in sum of all areas of the trapezoids of equal width in the volume rate versus time graph. The right Riemann sum with three intervals for this case is described below:
[tex]Q = \Sigma \limits_{i=0}^{2} \left\{R_{i}+\frac{1}{2}\cdot [R_{i+1}-R_{i}] \right\}\cdot \Delta t[/tex]
[tex]Q = \left[6.5+\frac{1}{2}\cdot (6.2-6.5) \right]\cdot (3.667)+\left[6.2+\frac{1}{2}\cdot (5.9-6.2)\right]\cdot (3.667) +\left[5.9+\frac{1}{2}\cdot (5.6-5.9) \right]\cdot (3.667)[/tex]
[tex]Q \approx 66.556\,L[/tex]
The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters. [tex]\blacksquare[/tex]
Remark
The table of the volume rate versus time is missing, all missing values of the table are included below:
[tex]R(4) = 6.5\,\frac{L}{h}[/tex], [tex]R(7.667) = 6.2\,\frac{L}{h}[/tex], [tex]R(11.333) = 5.9\,\frac{L}{h}[/tex], [tex]R(15) = 5.6\,\frac{L}{h}[/tex]

Answer:
75?
Step-by-step explanation:
Isnt the total of the line suppose to equal 180*? if thats the case then the first angle 101* is 11 over the 90* mark meaning that you take 11 from the other side which would be 90-11 and that leave you with 79 but since the problem says +4 you would take 4 from 79 leaving you with 75. You would work backwards on the problem so the whole thing equals 180*

a sample representative of the entire population is an
[A] Biased sample
[B] unbiased sample
[C] convenience sample
[D] free sample
Answer:
unbiased sample
Step-by-step explanation:
The population is divided into similar, nonoverlapping groups. A simple random sample then selected from each group.
A biased sample is the opposite of unbiased sample.
Answer:
[B] unbiased
Step-by-step explanation:
Let's first define each answer choice;
Biased sample: sample not representative of the entire population.
Unbiased sample: sample where every member of the population has an equal chance of being selected.
Convenience sample: sample where representatives are easily accessible.
Free sample: Sample of small amount
Thus, base on the define of the answer choices we can know that
[B] unbiased sample is the correct answer.

Anna had a solid wooden dowel with a length of 12 inches and a diameter of 1 inch, as shown below. She cut a two-inch portion out of the dowel as indicated. What was the volume, to the nearest tenth of a cubic inch, of the portion of the dowel that Anna cut out?
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.
It is about 30,000 light years from our solar system to the center of the milky way Galaxy. the solar system revolves around the center of the milky way with an angular velocity of about 2.6 * 10^-8 radians per year. what distance does the solar system travel in its orbit each year?
The solar system travels about [] light years each year.
Given that a light year is about 5.88 * 10^12 miles, how fast is the solar system circling the center of the Galaxy in miles per hour? Found your answer to the nearest ten thousand.
The solar system is circling the center of the galaxy at about [] mi/hr.
a. The solar system travels about 188495.56 light years each year.
b. the solar system is circling the center of the galaxy at about 520000 mi/hr
a. Distance solar system travels each year.
The solar system travels about 188495.56 light years each year.
Since the distance the solar system travel around the milky way is a circular orbit. The distance travelled is the circumference of a circle.
So, the circumference C = 2πr where
r = radius of circle = distance of solar system from center of milky wat = 30000 light yearsSo, C = 2πr
= 2π × 30000 light years
= 60000π light years
= 188495.56 light years
So, the solar system travels about 188495.56 light years each year.
b. Speed of solar systemThe solar system is circling the center of the galaxy at about 520000 mi/hr
The speed of the solar system circling the milky way is given by v = rω where
r = radius of orbit = 30000 light years = 30000 × 5.88 × 10¹² miles = 1.764 × 10¹⁷ miles and ω = angular velocity of solar system = 2.6 × 10⁻⁸ radians per year = 2.6 × 10⁻⁸ radians per year × 1year/365 days × 1 day/24 hours = 2.6 × 10⁻⁸ radians/8760 hour = 2.97 × 10⁻¹² radians per hourSo, substituting the values of the variables into the equation, we have
v = rω
v = 1.764 × 10¹⁷ miles × 2.97 × 10⁻¹² radians per hour
v = 5.23908 × 10⁵ miles/hour
v = 523908 miles/hour
v ≅ 520000 mi/hr to the nearest ten thousand
So, the solar system is circling the center of the galaxy at about 520000 mi/hr

Jim just found a job with a take-home pay of $1,950 per month. He must pay $1,200 for rent and $200 for groceries each month. He also spends $200 per month on transportation. If he budgets $50 each month for clothing, $100 for restaurants and $50 for everything else, how long will it take him to put together emergency savings of $1,500?
Add all his expenses together:
1200 + 200 + 200 + 50 + 100 + 50 = $1,800
Subtract his expenses from his pay:
1950 - 1800 = 150
Divide how much the emergency savings is by the amount left over per month:
1500/150 = 10
it will take 10 months
