Answer:
x = 52
Step-by-step explanation:
∡RQS = 180 - (90 + 34)
∡RQS = 56°
∡PQS + ∡RQS = 180°
∡PQS = x + 72
x + 72 + 56 = 180
x + 128 = 180
x = 52
Answer:
544 units²
Step-by-step explanation:
The surface area is the sum of the areas of the three rectangular faces and the two triangular bases.
SA = 10×14 +10×14 +12×14 + 2(1/2)(12)(8)
= 14×(10+10+12) +12×8
= 448 +96
= 544 . . . . square units
_____
The area of a rectangle is the product of its dimensions:
A = LW
The area of a triangle is half the product of its base and height:
A = (1/2)bh
Here, both triangles have the same area, so we multiplied the area of one of them by 2 to get the area of both of them.
Answer: The system of inequalities would be,
x + y ≤ 130, x > 0.25y, x ≥ 0, y ≥0
Step-by-step explanation:
Here, x represents the amount to be planted in tomatoes and y represents the amount to be planted in cucumbers, ( in square ft )
Thus, the total area required ( in square ft )= x + y
Since, the available area = 130 ft²,
⇒ Total area ≤ 130 ft²
⇒ x + y ≤ 130,
∵ the area planted with tomatoes to be more than 25% of the area planet with cucumbers,
⇒ x > 25% of y
⇒ x > 0.25y
Also, area can not be negative,
⇒ x ≥ 0, y ≥ 0
