1/2 + 1/4 + 2/5
=(2+1)/4 + 2/5
=3/4 +2/5
=(3*5+2*4)/4*5
=(15+8)/20
=23/20
Answer:
I'm assuming a 1:10 scale. So then that means the 10 by 15 feet should be divided by 10. The blueprint area is 1 ft by 1.5 ft.
Step-by-step explanation:
Y=1.47x
X is the number of erasers bought
No. 1/12 is a smaller amount than 1/3.
Arc PQR measures 210°
An intercepted arc measures twice the intercepted angle. Here, the intercepted angle is ∠PSR. Hence:
Arc PQR = 2 * ∠PSR
1.) Compute for ∠PSR first. Opposite angles in a quadrilateral measures 180°. Hence:
∠PQR + ∠PSR = 180°
75° + ∠PSR = 180°
∠PSR = 180° - 75°
∠PSR = 105°
2.) Proceed with computing Arc PQR:
Arc PQR = 2 * ∠PSR
= 2 * 105°
= 210°
