A group of friends in Chicago watched a televised bullfight. They ordered 3 pizzas ($15 each), 15 drinks ($1.50 each), and 6 large nachos ($5.80 each). After adding 5% and a 20% tip to the total, what did they pay for the food? (The tip is 20% of the total before the tax is added) around the answer to the nearest while cent
Answer:
$127.875
Step-by-step explanation:
cost of 3 pizzas= $15*3
cost of 3 pizzas=$45
cost of 15 drinks=$1.50*15
cost of 15 drinks=$22.5
cost of 6 nachos=$5.80*6
cost of 6 nachos=$34.8
Total cost = pizza cost+ drinks+nachos
total cost=$45+$22.5+$34.8
total cost=$102.3
Now ,
Tip cost=$102.3*20%
=$20.46
tex cost=$102.3*5%
=$5.115
Bill which all friends pay=total cost+ tip cost+tex cost
= $102.3+$20.46+$5.115
=$127.875

Solve the formula for the specified variable P=wm
Answer:
below
Step-by-step explanation:
I'm not sure what variable you want to solve for but I'll solve for w and m if needed.
p = wm
~Divide w to both sides
p/w = m
p = wm
~Divide m to both sides
p/m = w

PLS HELP WILL MARK BRAINLIEST IF GOTTEN RIGHT!
Answer:
3 feet
Step-by-step explanation:
The equation modeled by this throw is
-16t^2+8t+2
Using the vertex x coordinate formula of -b/2a,
we find that the x coordinate of the vertex is 0.25. Subbing 0.25 seconds for t into -16t^2+8t+2, we find out that the y value of the vertex is 3. This means the highest point reached by the ball is 3 feet and this takes 0.25 seconds
Write the perimeter of the triangle as a simplified expression
Perimeter=sum of sides
[tex]\\ \qquad\quad\sf\longmapsto Perimeter=6y+3y+5+y-4[/tex]
[tex]\\ \qquad\quad\sf\longmapsto Perimeter=6y+3y+y+5-4[/tex]
[tex]\\ \qquad\quad\sf\longmapsto Perimeter=9y+y+1[/tex]
[tex]\\ \qquad\quad\sf\longmapsto Perimeter=10y+1[/tex]
The simplified expression of the perimeter of the given triangle is 10y + 1
Use the concept of a triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
In the given figure:
Hypotenuse = 6y
Perpendicular = 3y + 5
Base = y - 4
The perimeter of a triangle = Hypotenuse + Perpendicular + Base
Therefore,
Perimeter of the triangle = 6y + 3y + 5 + y - 4
Perimeter of the triangle = 10y + 1
Hence,
The perimeter of the triangle is 10y + 1.

Show how find 42 x 27 using an area number
Answer:
First break it down
42= 40 & 2
27= 20 & 7
Then times 40 & 20 to get 800
20 x 2 to get 40
40 x 7 to get 280
7 x 2 to get 14
Now add them all together.

episode the ratio of males to females were 3 to 9 if there are 360 people at the fair how many males are there exact answer
Answer:
90 males
Step-by-step explanation:
3 males plus 9 females is 12 overall.
360/12 is 30 for each "1".
30 multiplied by 3 males is 90 males.

10. A rectangle has width the same as a side of a square whose perimeter is 20 m. the length
of the rectangle is 9 m. Find the perimeter of this rectangle.
Answer:
The perimeter of the rectangle is 28m
Step-by-step explanation:
Perimeter of a square = 4 x side length
20 = 4 x side length
side length = 20/4 = 5m
width of rectangle = 5m
length of rectangle = 9m
Perimeter of rectangle = 2(l + w)
= 2(9 + 5)
= 2(14)
= 28m
calculate the absolute value
| 4 - 3x | = 5x + 4
Recall the definition of absolute value:
• |x| = x if x ≥ 0
• |x| = -x if x < 0
So we have 2 cases to consider:
• If 4 - 3x ≥ 0, then |4 - 3x| = 4 - 3x, and we have
4 - 3x = 5x + 4
8x = 0
x = 0
• If 4 - 3x < 0, then |4 - 3x| = -(4 - 3x) = 3x - 4, which gives
3x - 4 = 5x + 4
2x = -8
x = -4
However, keep in mind that |x| is always non-negative. If x = -4, then the right side of the equation becomes
5(-4) + 4 = -20 + 4 = -16 < 0
so the solution in this case is extraneous.

find the defference between 5 2/7 and 2 2/4
Answer: 39/14
Step-by-step explanation:
Given
5 2/7 - 2 2/4
Convert mixed fraction to improper fraction
5 2/7 = (5 × 7 + 2) / 7 = (35 + 2) / 7 = 37/7
2 2/4 = (2 × 4 + 2) / 4 = (8 + 2) / 4 = 10 / 4 = 5/2
Find the common denominator for 37/7 and 5/2
First 10 multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
First 5 multiples of 7 = 7, 14, 21, 28, 35
Since 14 is the first common multiple in the lists, 14 would be the common denominator of 37/7 and 5/2
Convert to the common denominator
(37 × 2) / (7 × 2) = 74 / 14
(5 × 7) / (2 × 7) = 35 / 14
Simplify by subtraction of numerator
=74/14 - 35/14
=(74 - 35) / 14

An angle has a measure of n degrees. Which of the following expressions would be used to find the measure of its complement?
a. n - 90
b. 90 -n
c. 180 - n
d. n - 180
9514 1404 393
Answer:
b. 90 -n
Step-by-step explanation:
The sum of an angle and its complement is 90 degrees. If c represents the complement, this means ...
n +c = 90
c = 90 -n . . . . . . . . . subtract n from both sides of the equation
The expression 90 -n can be used to find the complementary angle.
Given: Circle W W (-4, 6) Radius = 10 Units Which point lies on circle W?
The solution is : Option A is correct; Point Q is outside circle W
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
If the circle is given as having center W, this means the radius starts from point W and ends at any point on the circumference.
The radius has been given as 5 units, and this also means any measurement from point W to the circumference is either equal to or less than the radius which is 5 units.
Any measurement that is greater than 5 would be outside of the circumference.
we have,
Point Q is 6 units away from point W, therefore point Q is outside the circumference, that is, outside circle W.
