Answer:
Perimeter of the quadrilateral PQRS is 25 units
Step-by-step explanation:
From the figure attached,
PQ is a tangent to the given circle so m∠PQR = 90°
Now we apply Pythagoras theorem in the ΔPQR,
PR² = PQ² + QR²
(PT + TR)²= PQ² + 5²
(4 + 5)² = PQ² + 25
81 = PQ² + 25
PQ = √(81 - 25)
= √56
≈ 7.5 units
PQ ≅ PS ≅ 7.5 units
[Since measures of tangents drawn from a point to a circle are always equal]
Perimeter of PQRS = PQ + QR + RS + PS
= 7.5 + 5 + 5 + 7.5
= 25 units
Therefore, perimeter of the quadrilateral PQRS is 25 units.
Answer:
It would be 3C, 2C, 0C, -6C, -7C, -9C, then -18C
Step-by-step explanation:
This is because the larger a postive number is above 0, the greater it is. Along with this, the smaller a negative number is, the less it is.
-x + 10 = 3x + 22
-12 = 4x
x = -3
Answer:
950 mouse traps are made in a day.
Step-by-step explanation:
Given:
Mouse traps produced in 30 minutes = 50
Total working hour in one day = 10 hours
Lunch break time = 30 minutes
To find:
Number of mouse traps are made in a day = ?
Solution:
Total number of working hours =10 hours
We know that 1 hours = 60 minutes
so 10 hours = 60 x 10 = 600 minutes
It is said that there is 30 minutes break
So total working hour is 600-30 = 570
In 570 minutes we have =
=19 half hours
Now the total mouse traps produced is 19 half hours is
19 x 50 = 950
