Answer:
180 feet
Step-by-step explanation:
The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.
But,
1 inch = 12 feet
So that,
48 inches = x feet
⇒ x = 
= 4
Thus,
48 inches = 4 feet
The number of feet of fabric needed for 45 curtains can be determined as:
45 x 4 feet = 180 feet
Therefore, 180 feet of fabric would be needed to make 45 curtains.
Answer:
16,17 and 18
Step-by-step explanation:
In statistics mode of a set of entries is the entry which is repeated maximum. There can be more than one mode in a set of entries. These are called mode,
Bimode ( two mode ) , trimode ( three mode ) and Multimode ( four or more ) .
Hence here our set of entries is,
20,17,16,17,18,16,18,19
arranging them in ascending order
16,16,17,17,18,18,19,20
hence in this case we see that 16,17and 18 all are getting repeated for two times, the maximum.
Hence we have a trimode here
16,17,18
Answer:
60cm^2
Step-by-step explanation:
The formula for the area of a trapezium is : 
To work out the area of the trapezium you would first have to add the lengths at the top and bottom (a and b) which is 9+15, this gives you 24cm.
The next step is to divide the value of 24 by 2, this gives you 12cm.
The final step is to multiply the value of 12cm by the height of 5, this gives you 60cm^2. This is because if you were to substitute the values into the formula you would get the same answer.
1) Add 9 and 15.

2) Divide 24 by 2.

3) Multiply 12 and 5.
Answer:
144
Step-by-step explanation:
Answer:
The value of x is 5 units ⇒ C
Step-by-step explanation:
In the given figure
∵ Δ ABC is a right triangle at vertex B
∵ AC is its hypotenuse
∵ BD ⊥ AC
∴ (BD)² = AD × DC
∵ BD = 10 units
∵ AD = x units
∵ DC = 4x units
→ Substitute them in the rule above
∴ (10)² = x × 4x
∴ 100 = 4x²
→ Divide both sides by 4
∵
= 
∴ 25 = x²
→ Take √ for both sides
∴ 5 = x
∴ The value of x is 5 units
