Wooden flooring costs £35 per square metre. The floor is then edged with a narrow wooden strip which costs £4 per metre.

How much does it cost for a 6m by 4m room, including the edging?

Wooden Flooring Costs 35 Per Square Metre. The Floor Is Then Edged With A Narrow Wooden Strip Which Costs

Answers

Answer 1

Answer:

£920

Step-by-step explanation:

We need to find the area of floor to find the cost of the flooring, and then we need to find the perimeter of the floor to find the cost of the edging.

A = LW = 6 m × 4 m = 24 m²

Cost of flooring: 24 m² × £35/m² = £840

P = 2(L + W) = 2(6 m + 4m) = 2(10m) = 20 m

Cost of edging: 20 m × £4/m = £80

Total cost:

£840 + £80 = £920

Write an expression using subtraction to find the distance between the two jellyfish. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)

Answers

not 100% sure since you didnt show us an image

we change this number 1.5=15/10=3/1 and 0.5=5/10=1/2

it will show on the number line!

The expression using subtraction to find the distance between the two jellyfish is 0.5 - (-1.5).

The distance between the two Jellyfish is 2.

We have,

The point of A on the number line: -1.5

The point of B on the number line: 0.5

Now,

To find the distance between the two jellyfish.

= B - A

= 0.5 - (-1.5)

= 0.5 + 1.5

= 2

Thus,

The expression using subtraction to find the distance between the two jellyfish is 0.5 - (-1.5).

The distance between the two Jellyfish is 2.

Answers

Answer:

8,100

Step-by-step explanation:

7,200 - 6,400 = 800 increased in 50. Years

What percentage is 800 of 6,400 (%/100 = is/of)

x/100 = 800/6400 (cross multiply)

(800*100)/6400 = 12.50%

(12.50 * 7200)/100 = 900 increased

7,200 + 900 = 8,100

A line that includes the point (16, 15) has a slope of 0. What is its equation in
slope-intercept form?

Answers

9514 1404 393

Answer:

  y = 0x + 15

Step-by-step explanation:

A line with a slope of 0 is a horizontal line. It has the same y-value everywhere. If it goes through the point (16, 15) with y-coordinate 15, then its y-intercept is 15.

Writing the slope explicitly, the equation is ...

  y = 0x +15

Simplified, the equation is

  y = 15

A water tank is a cube of side 2m the depth of water in it is60cm. What is the volume of water in the tank?

Answers

Answer:

Step-by-step explanation:

The base is made of a square that is 2 meters by 2 meters.

Base = 4 m^2

The height of the water is 60 cm

60 cm// 100 cm/meter = 0.6 meters

Volume = Base * height

Base = 4m^2

height = 0.6 m

Volume = 4 * 0.6 = 2.4 m^3
