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?
Answers
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

Under his cell phone plan, Alonso pays a flat cost of $53.50 per month and $3 per gigabyte. He wants to keep his bill at $59.80 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Alonso can use while staying within his budget.
Answers
Answer:
Alonso can use 2.1 gigabytes while staying within his budget.
Step-by-step explanation:
53.50 + 3x = 59.80
3x = 59.80 - 53.50
3x = 6.3
x = 6.3 ÷ 3
x = 2.1

Perpendicular to y=-3x+11 and goes through the point (-9,-6)
please help it’s due next period
Answers
Answer:
y = 1/3x - 3
Step-by-step explanation:
If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.
So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)
y = 1/3x + c
Next, substitute x = -9, and y = -6 to find the y intercept, or c:
-6 = 1/3(-9) + c
-6 = -3 + c
c = -6 + 3
c = -3
The equation of the line is y = 1/3x - 3

The table represents the ratio of tulips todaffodils in a garden how many tulips will there be if the garden has 60 daffodils
Answers
There would be 85 Tulips in the garden if the garden has 60 daffodils
Two variables are said to be proportional if an increase in one variable leads to an increase in another variable and vice versa.
From the table, 12 daffodils corresponds with 17 Tulips.
Hence the ratio of tulips to daffodils = 17 tulips / 12 daffodils
Therefore for 60 daffodils:
Number of Tulips = (17 tulips / 12 daffodils) * 60 daffodils
Number of Tulips = 85 Tulips
There would be 85 Tulips in the garden if the garden has 60 daffodils

hope this helps <3
Answer:
Step-by-step explanation:
x= 50
y+25=180(because it is on a straight line)
y+25=180
y+25=180
y+25-25= 180-25
y+0= 155
y= 155
z+ y=180
z+ 155= 180
z+ 155- 155 =180-155
z+ 0 = 25
z = 25
x = 50
y = 155
z = 25

3. What is 11% of $3,000? • A) $250 e B) $300 • C) $380 • D) $350
Answers
Answer:
$330.00
Step-by-step explanation:
Hey there!
The word ‘of’ in math means multiply
And
11% of 3,000
= 11/100 * 3,000
= 11/100 * 3,000/1
= 11(3,000)/100(1)
= 33,000/100
= 33,000 ÷ 100/100 ÷ 100
= 330/1
= 330
Therefore, the answer is most likely: 330
