If you are buying at item at a store for a price of $61, and there is a 6.7% tax added on top, what would be the total amount due at the register, to the nearest cent?
Answers
Answer:
The total amount due at the register will be: $65.09
Step-by-step explanation:
The cost of an item = $61
tax on item = 6.7%
The tax amount = 6.7% × 61
= 0.067 × 61
= $ 4.09
The total cost = cost of an item + tax amount
= $61 + $4.09
= $65.09
Therefore, the total amount due at the register will be: $65.09

A passenger in an airplane looks out the window and spots the airport in the distance. The angle of depression to the airport is 63°, and the airplane is flying at 18,000 feet. What is the horizontal distance to the airport?
Answers
9514 1404 393
Answer:
about 9171 feet
Step-by-step explanation:
It can help to draw a diagram.
The relation between angle, opposite side, and adjacent side in a right triangle is ...
Tan = Opposite/Adjacent
tan(63°) = (18000 ft)/(horizontal distance)
horizontal distance = (18000 ft)/tan(63°) ≈ 9171 ft
The horizontal distance to the airport is about 9171 feet.

If HF = 6 units, then BF = 12 units.
Step-by-step explanation:
In ΔBCD, H is the centroid.
Given
HF = 6We know that the centroid is the point of intersection of the medians of a triangle.
Centroid divides a median in a 2:1 ratio.
In other words, the location of the centroid lies at 2/3 of the distance from the vertex along the segment BF that connects the vertex to the midpoint of the opposite side.
so
HF = 1/2 BF
substituting HF = 6
6 = 1/2BF
BF = 12 units
Therefore, if HF = 6 units, then BF = 12 units.
Answer:
HF = 6 units and BF = 12 units

write an equation for the n th term of the arithmetic sequence -4, 1, 6, 11 ... Then find a(50)
an equation is: a(n) = _n-_
a(50)= _
Answers
Answer:
see explanation
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 4 and d = a₂ - a₁ = 1 - (- 4) = 1 + 4 = 5 , thus
[tex]a_{n}[/tex] = - 4 + 5(n - 1) = - 4 + 5n - 5 = 5n - 9
Then
a(50) = 5(50) - 9 = 250 - 9 = 241
During a five-year period 24% of snowstorms in a certain city caused power outages. 57 of the snow storms did not cause power outages how many snow storms were in the city in the five-year period
Answers
Answer:
divide it and do multiply and add it and subtract it
The number of snow storms were in the city in the five-year period is 75.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, during a five-year period 24% of snowstorms in a certain city caused power outages.
Let the number of snow storms were in the city in the five-year period be s.
57 of the snow storms did not cause power outages.
So, the equation is
s -24% of s =57
s-0.24s=57
0.76s=57
s=57/0.76
s=75
Therefore, the number of snow storms were in the city in the five-year period is 75.

When a transversal intersects a
pair of parallel lines it will create
two pairs of alternate exterior
angles.
Ricky claims the angles within
each pair are congruent to each
other, but not congruent to
either angle in the other pair.
Answers
Answer:
Part A none
Part B drawn
Step-by-step explanation:
Suppose the transversal intersects a pair of parallel lines it creates two pairs of alternate exterior angles.
Now if we look at the first figure we find that the alternate exterior angle 1 and 4 are equal . Also 3 and 2 are equal.
But <1 and < 2 are not equal . They are supplementary angles. Their sum is equal to 180 degrees.
Similarly angles 3 and4 are supplementary angles.
This situation does not support Ricky's claim. So you will select none in part A.
Now in part B we see that angle 5 &8 are equal and 6 & 7 are congruent.
This refutes Ricky's claims and this can be proved mathematically.
Angles 5 & 6 are supplementary angles. Similarly 7 & 8 are supplementary therefore they cannot be equal as they are unequal and a transversal is drawn not a perpendicular.
The part A none and for part B drawn.
Suppose the transversal intersects a pair of parallel lines it creates two pairs of alternate exterior angles.
Now if we look at the first figure we find that the alternate exterior angle 1 and 4 are equal . Also 3 and 2 are equal.
What is the meaning of the supplementary angle?
Two angles are called supplementary when their measures add up to 180 degrees.
But <1 and < 2 are not equal because they are supplementary angles. and the sum is equal to 180 degrees.
Similarly angles 3 and 4 are supplementary angles.
This situation is not support Ricky's claim so select none in part A.
Now for part B we see that angle 5 &8 are equal and 6 & 7 are congruent.
This refutes Ricky's claims and this can be proved mathematically.
Angles 5 & 6 are supplementary angles. Similarly 7 & 8 are supplementary
Therefore they cannot be equal as they are unequal and a transversal is drawn not a perpendicular.
Therefore for the part A none and for part B drawn.

Two families go skiing on a Saturday. Together, they spend $95 on pizza at a local restaurant and $65.73 for breakfast. One family purchases two adult lift tickets and four youth lift tickets for $166. Another family purchases four adult lift tickets and five youth lift tickets for $263. How much would it cost two adults and five kids to ski for a day?
Answers
Answer:
$189
Step-by-step explanation:
We can create a system of equations to solve this equation. They are as follows:
[tex]2A + 4Y = 166\\4A + 5Y = 263[/tex]
In this case, I used "A" to represent adult lift tickets and "Y" to represent youth lift tickets.
We need to get one of the variable (A or Y) by itself in one of the equations. I am going to use the first equation.
[tex]2A = -4Y + 166\\A = -\frac{4}{2}Y + \frac{166}{2} \\A = -2Y + 83[/tex]
Now that we have A by itself we can plug it into the second equation.
[tex]4(-2Y + 83) + 5Y = 263\\-8Y + 332 + 5y = 263\\-3Y + 332 = 263\\-3Y = -69\\Y = 23[/tex]
We have found Y now lets plug it back into the first equation to find the value of A.
[tex]2A + 4(23) = 166\\2A + 92 = 166\\2A = 74\\A = 37[/tex]
Let's check our variables by plugging them both in to the second equation.
[tex]4(37) + 5(23) = 263\\148 + 115 = 263\\263 = 263[/tex]
Lastly, we can find out how much it would cost 2 adults and 5 kids to ski for a day, using this equation:
[tex]2A + 5Y = ?\\\\2(37) + 5(23) = ?\\\\74 + 115 = 189\\[/tex]
Therefore, 2 adult tickets and 5 kid tickets would cost $189.
Hope this helps!!
