Answer:
C.
Step-by-step explanation:
The sales tax is ≈ 12.74
The total of $93 - (12.74 + 73.89) = 6.37
$6.37 is approximatley 20%
The description of the service they received is
They left a 20% tip, so the service was probably above average.
What is percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
let the amount of tax be x.
So, 100% of x = 73.89 x 5.8%
x = 428.562/100
x= 4.285
Now, the tip amount would be
= 93 - 73.89 4.28
= $14.83
Now, the amount of tip in percent is
73.89 / 100 = 14.83 / x
x = 14.83 /0.7389
x= 20.07
x= 20%

Find the measure of the angle indicated.
Answer:
60 degrees.
Step-by-step explanation:
Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.
In this case, 11x-6 is equal to 10x.
11x-6 = 10x
-6 = -1x
divide -x both sides, you get x = 6.
Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.
---------------------------------------------------------------------------------------------------------
Since 10x is on a straight line, the angle next to it adds up to 180, so...
10x + y = 180.
We know that 10x = 60, so 60 + y = 180.
subtract both sides by 60, you get y = 120.
Now, you solved the whole graph.

The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?
Answer:
$2.19
Step-by-step explanation:
Given that :
Cost of 3 pounds of grape = $6.57
Cost in dollars = y ; number of pounds = x
Cost in dollars α number of pounds
Cost in dollars = k * number of pounds
k = constant of proportionality
$6.57 = k * 3
$6.57 = 3k
Divide both sides by 3
6.57 / 3 = 3k/ 3
2.19 = k
k = $2.19
Given congruent triangles ΔRST ΔLMN where MN = 33, LN = 54, and RT = 4x+6 . Find the value of x
Answer:
x=12
Step-by-step explanation:
We know that both triangles are congruent meaning corresponding parts are equal. We know that line LN=54 and that RT=LN meaning that RT also equals 54. With that information we can simply subtract 6 from 54 to get 48 then divide by 4 to get 12. Hope this helps!

How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?
9514 1404 393
Answer:
use the slope formula
Step-by-step explanation:
Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.
m = (y2 -y1)/(x2 -x1)
For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...
(hours, miles) = (1, 25) and (2, 75)
The corresponding slope on that interval is ...
m = (75 -25)/(2 -1) = 50 . . . . miles per hour
__
You can identify four (4) regions on this graph in which the slope is constant:
(0, 1) . . . slope is 25 mph
(1, 2) . . . slope is 50 mph, as computed above
(2, 3) . . . slope is 0 (the rider has stopped)
(3, 5) . . . slope is 25 mph
Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

32 + 42 + x = 180
x = 106
Can someone help me with this problem
Answer:
x = 43
Step-by-step explanation:
lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14
this means that 143 would have to be congruent to 3x + 14
so we can set the equation to 3x + 14 = 143
subtract 14 from both sides: 3x = 129
divide both sides by 3: x = 43

The table shows the prices of some candy items at a store. Jake selected 1.6 pounds of Fruit Chews and 2.6 pounds of Jelly Beans. The sales tax for his purchase was $0.52.
Item Price Per Pound.
Fruit Chews. $4.70
Jelly Beans. $2.35
Chocolate. $3.50
If Jake had $25 to spend at the candy store, how much money did Jake have left after his purchase?
Answer:
10.85
Step-by-step explanation:
1.6 x 4.70 + 2.6 x 2.35 = 7.52 + 6.11 = 13.63 + .52 = 14.15
25 - 14.15 = 10.85

b) Factorise
Factorise y2 + 2y - 24
Answer:
(y + 6)(y - 4)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] y² + 2y - 24
The factors of -24 that sum to 2 are 6 and -4.
So,
[tex] \longrightarrow [/tex] y² + (6 - 4)y -24
[tex] \longrightarrow [/tex] y² + 6y - 4y - 24
[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)
[tex] \longrightarrow [/tex] (y + 6)(y - 4)
Answer:
( y-4) ( y+6)
Step-by-step explanation:
= y^2 + ( 6 - 4)y - 24
= y^2 + 6y - 4y - 24
= y( y + 6) - 4(y + 6)
= ( y - 4 ) ( y + 6)
