A trip, including hotel and air, is prices at $319.19 after tax. If the tax rate is 12%, calculate the price before tax that will result in this tax-included amount
Answer: $285
Step-by-step explanation:
Given
A trip costs [tex]\$319.19[/tex] after-tax inclusion
The rate of tax is 12%
Suppose x is the amount of charge before tax inclusion
We can write
[tex]\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285[/tex]
The amount before tax inclusion is $285
Mark uses his calculator for 80% of his maths homework
questions. Twelve questions are answered with his calculate
How many questions does Mark have for homework
Answer:
The number of questions in Mark's homework is:
60 questions.Step-by-step explanation:
To identify the number of questions of the homework, first, you must identify the percentage that is the 12 question Mark calculates by himself: if in 80% he uses calculator, in 20% he doesn't, I mean, he uses his own calculates, by this reason:
20% = 12 questions of the homework.With this data, we can use a simple rule of three and find the number of question that correspond to 80%.
If:
20% = 12 questions80% = xThen:
[tex]x=\frac{80*12}{20}[/tex] (you can use the percentage if you want, the result is the same)[tex]x=\frac{960}{20}[/tex][tex]x=48[/tex]At last, we add the 80% and the 20% of the questions:
Total of questions = 80% with calculator + 20% with his calculatesTotal of questions = 48 questions + 12 questionsTotal of questions = 60 questionsAs you can see, the number of questions in Mark's homework is 60 questions.

As an unknown drone is detected by a radar dish hovering over a secure location in Washington dc the initial reading of the radar dish was detects the drone .The reading of the radar dish indicates an angle of elevation of 60 to the drone
Answer:
60° ; 30°
27.71 km
Step-by-step explanation:
Since we have a right angled triangle, and also the sum of the angles in a triangle is 180°
Angle of elevation is given as 60°
Hence, we have :
90°+60°+x ° = 180°
x = 180 - 150
x = 30°
The two acute angles are 60° and 30°
The altitude, h of the drone can be obtained thus :
Using trigonometry :
Sin θ = opposite / hypotenus
Sin 60 = h / 32
h = 32 * sin 60
h = 27.71 km

Find the area of the trapezoid.
31 cm
25.4 cm
-13.1 cm
Answer:
369.42
Step-by-step explanation:
A=a+b
2h=31+25.4
2·13.1≈369.42
Answer: -10.31494 liters
Step-by-step explanation:
Area of a trapezoid is found with the formula, A=(a+b)/2 x h.rounded to the nearest tenth would be 10.3 liters.

PLSS I NEED HELP boys and girls lil like Frl
Answer:
A
Step-by-step explanation:
In A, the number of bags that had more than 19 skittles is 7 and the number of bags that had less than 19 skittles is 16, so A is true.
In B, the median package contained 18 candies.
In C, 5 bags contained 18 candies, while there were 8 bags in total for the 17 and 20 bags.
In D, the range is the highest value minus the lowest, so it's 22-12=10.
Find the perimeter of the figure to the nearest hundredth.
Answer:
65.12 mm
Step-by-step explanation:
Circumference of semicircle = 8π mm
Perimeter = (40 + 8π) = 65.12 mm
What is the perimeter, to the nearest inch, of the kite?
Step-by-step explanation:
In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.

Applying the Pythagorean theorem, solve this triangle.
Answer:
[tex]y = \sqrt{ {14}^{2} - {10}^{2} } \\ y = \sqrt{96} \\ y = 9.8[/tex]
Answer:
Step-by-step explanation:
using pythagoras theorem
h^2=p^2+b^2
14^2=10^2+b^2
196=100+b^2
196-100=b^2

Spread is the greatest number minus the smallest number which would be 9-4=5.
The center is the middle of all the values written out, 4,6,7,9, and 9 which would make the center 7.
Twice a number plus 6 times the number is 72
Answer:
9
Step-by-step explanation:
Let the no be x
By the conditions given ,
2x + 6x = 72
8x = 72
x = 72/8
x = 9
therefore the no is 9
[tex](2 \times x) + (6 \times x) = 72 \\ 2x + 6x = 72 \\ 8x = 72 \\ x = 72 \div 8 \\ x = 9[/tex]
