How much will the bill be without the service charge?

You receive the bill for a meal at a restaurant. The total for the meal, including a discretionary 10% service charge, is £61.60.
You feel that the service you received was poor, and you ask for the service charge to be removed from the bill.
How much will the bill be without the service charge?

Answers

Answer:

The original bill (without the added charge) is 56.00

Step-by-step explanation:

10% was added to the bill and that made it 61.60

So 61.60 = 110% of the original bill.

If the original amount was x, then

61.60 = 1.10x

x = 61.60/1.10

x = 56.00

find the surface area

Answers

Answer:

Surface area = 207 cm²

Step-by-step explanation:

Surface are of triangular prism = 2×BA + P × H

Base Area (BA) = ½*bh

b = 8 cm

h = 9 cm

BA = ½*8*9 = 36 cm²

Perimeter of triangular base (P) = 8 + 9 + 10 = 27 cm

Height for prism (H) = 5 cm

Surface area = 2 × 36 + 27 × 5 = 72 + 135

Surface area = 207 cm²

The sum of 88 elephants and x
elephants is 145 elephants.

Answers

57 elephants = x
Hope this helps

Answer:

x=57

Step-by-step explanation:

To solve this problem we need to make an equation to use to solve x.

The sum of 88 and x will equal 145 so the equation will look like this, 88 + x = 145.

Whatever x is, it has to add with 88 to make 145 so we have to use reverse operations.

The opposite of addition is subtraction so we subtract 88 from 145 like so. 145 - 88 = 57, which means x = 57.

The right triangle has a base length of 30yd and a perpendicular of 50yd. The area of a right triangle can be found with 0.5bp. The area would be 750yd. 1500 + 750 = 2250yd

Find the equation of a line which has:
slope of -2 and
crosses the y-axis at 5

in slope-intercept form

Answers

Answer:

y = -2x + 5

Step-by-step explanation:

Recall that slope-intercept form is y = mx + b where m is the slope and b is the y intercept

In this case our slope is m = -2

and, line crosses y-axis at 5 which is b = 5

thus, y = -2x + 5
