Answer:
$ 30.8Step-by-step explanation:
ratio and proportion:
3 tickets = 7 tickets
$13.20 x
then cross multiply: 3 (x) = 13.20 (7)
simplify: 3x = 92.4
solve for x = 92.4 / 3
x = $ 30.8
therefore,
7 tickets costs $ 30.8

The height of a building is 72 m. Find the angle of elevation from a point on ground level that is 55 m away from the base of the building
Answer:
52.6 degrees
Step-by-step explanation:
tan^-1(72/55)
Angle of elevation is equals to 52°7'(approximately).
What is angle of elevation?
" Angle of elevation is the angle between the horizontal plane and line of sight from the point of observation."
Formula used
In a right angled triangle,
tanθ = ( opposite side) / adjacent side)
According to the question,
As shown in diagram
Height of the building (AB) = 72m
Distance between base of the building and point of observation
(BC)= 55m
Angle of elevation = θ
Substitute the value in the formula we have,
tanθ = AB / BC
= 72 / 55
⇒ θ = tan⁻¹ (72 /55)
= tan ⁻¹(1.3091)
= 52° 7' (approximately)
Hence, angle of elevation is equals to 52°7'(approximately).

6) in Minnesota sales tax is 6.875%.what is the total (including tax) on items that total $178.46?
Answer:
5. 34% 6. $190.73
Step-by-step explanation:
trust man just trust
Answer:
5) 52
6) $190.73
Step-by-step explanation:
5)
Let the unknown number be x.
40 is 77% of x
40 = 0.77x
Divide both sides by 0.77
x = 52
Answer: the number is 52.
6)
We first calculate the amount of tax which is 6.875% of $178.46.
6.875% of $178.46 =
= 0.06875 * $178.46
= $12.27
The amount of tax is $12.27.
Now we add the amount of tax to the price before tax.
$178.46 + $12.27 = $190.73

Ok last one my sis needs help on lol again I’m doing my homework and cAnT HeLp rn pls just help lol
Answer:
Part A: 15.55
Part B: 0.45
Step-by-step explanation:
Part A:
The giraffe is already 14.29 so when you add the length of its tongue (equation 14.29 + 1.26) then that would equal 15.55
Part B:
The giraffe is trying to eat some leaves that are 16 feet above the ground so you would subtract 16 - 15.55 to see how much farther it needs to reach, so the answer is 0.45.
(This is what I got, I apologize if I get this wrong. If I messed up on something, someone please correct me, thank you and have a nice day!)
Answer:
Part A: It can reach 15.55 feet.
Part B: Need to reach 0.45 feet farther to get to the leaves of a 16 feet tree.
Step-by-step explanation:
giraffe + tongue = reach
14.29 + 1.26 = 15.55
tree height - giraffe reach = extra distance
16 - 15.55 = 0.45 feet

Answer:
Step-by-step explanation:
Tran earns $16 per hour and is paid a flat fee of $46 each week. At
the end of the week her total salary can be represented by the
equation y=16x + 46, where x is the number of hours, and y is the
total weekly salary. Write this relationship in functional notation, as a
function S(h), where S(h) represents the salary for h number of hours.
Answer:
[tex]S(h)=16h+46[/tex]
Step-by-step explanation:
We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].
So we get the answer of: [tex]S(h)=16h+46[/tex]

At the park, a statue stands on a marble base. The statue and marble base have a total height of 59.4 inches. The height of the marble base is 16.09 centimeters. Given that 1 inch is equal to 2.54 centimeters, what is the height of the statue?
Answer:
134.786 centimeters
Step-by-step explanation:
First you need to convert inches to cm by doing 59.4x2.54=150.876 then you subtract 16.09 from that. Your answer would be 134.786 centimeters
Find the intercepts of the graph given the following equation 4x – 3y = 12
Answer:
y-intercept: -4 or (0, -4)
x-intercept: 3 or (3, 0)
Step-by-step explanation:
4x - 3y = 12
we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept
4x - 3y = 12
-3y = -4x + 12
y = 4/3x - 4
So the intercept is -4 or (0, -4).
For the x-intercept, we can make the y value 0 to solve for x.
4x - 3y = 12
4x - 3(0) = 12
4x = 12
x = 3
So the x-intercept is 3 or (3, 0).

An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 3 1 3 yards of paper for one box and 5 6 yard of paper for the other box. The paper must be cut into pieces that are 1 6 yard long. How many pieces will the student cut to use for the gift boxes?
Answer:
25 pieces
Step-by-step explanation:
Given
[tex]Box_1 = 3\frac{1}{3}[/tex]
[tex]Box_2 = \frac{5}{6}[/tex]
[tex]Pieces = \frac{1}{6}[/tex] yard
Required
Determine the number of pieces
First, we need to determine the total yards of paper
[tex]Total = Box_1 + Box_2[/tex]
[tex]Total = 3\frac{1}{3} + \frac{5}{6}[/tex]
[tex]Total = \frac{10}{3} + \frac{5}{6}[/tex]
[tex]Total = \frac{20 + 5}{6}[/tex]
[tex]Total = \frac{25}{6}[/tex]
Divide by the size of the pieces to get the number of pieces
[tex]Number = Total/Pieces[/tex]
[tex]Number = \frac{25}{6} / \frac{1}{6}[/tex]
[tex]Number = \frac{25}{6} * \frac{6}{1}[/tex]
[tex]Number = \frac{25}{1} * \frac{1}{1}[/tex]
[tex]Number = 25[/tex]

Charlie is reading about animal hearts in a kids science magazine. He learns that a nestling (young) Striped Horned Owls heart weighs approximately 1.072 grams and blue whale's heart weighs 400 lbs. He is eager to share what he learned with his friends over lunch the next day and tells them that a blue whale's heart and a striped horned owl's heart are two orders of magnitude apart. Do you agree with Charlie's statement? Explain.
Answer:
Charlie's statement is incorrectStep-by-step explanation:
Given that the owls heart weighs 1.072 grams
and the Whale's heart weighs 400lbs
let us convert from pounds to grams to have a uniform unit
400lbs = 181,437grams
Now when two readings or quantities are two orders apart it means that they differ by a factor of 100
let us solve for the difference between the two hearts
181,437grams- 1.072 grams= 181 435.928 grams
the difference is more than two orders, hence the statement is not correct

Select True or False. (1 point)
The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x.
True
or
False
Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation:
4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS;
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this;
4x − 2(5x − 1)
= 4x - 10x +2
= -6x + 2 or 2 - 6x
We see that the solution give is false.
