Answer:

2250yd

Step-by-step explanation:

There are two picnic sections: a right triangle and a rectangle. The area of a rectangle can be found with A= l * b, meaning the area of the rectangle would be A= 60 * 25 = 1500yd. 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 this case our slope is m = -2

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

thus, y = -2x + 5

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
