We have to divide 48 by 3 using distributive property.
Division using distributive property is used as it is much easier and accurate.
For dividing 48 by 3, we split first 48 as a multiple of 3 and 10
i.e. 48 = 30+18
Now divide again 18 as 3x5 +3
i.e. 48 = 30+15+3
By distributive property we have 48/3 = (30+15+3)/3 =30/3 +15/3 +3/3
Now easier to calclate this
30/3 = 10 : 15/3 =5 and 3/3 =1
Hence 48/3 = 10+5+1=16
Answer:
135 degrees
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
substitute
step 2
Remember that the circumference of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the measurement of the central angle (in degrees) that intercepts an arc with a length of 9π/2 ft
Answer:
14.25 yd^2
Step-by-step explanation:
The triangle area is given by the formula ...
A = 1/2bh
Here, the base is 10 yd, and the height is 5 yd, so ...
triangle area = (1/2)(10 yd)(5 yd) = (5 yd)^2 = 25 yd^2
__
The semicircle is half the area of a circle with radius 5 yd, so its area is ...
semicircle area = (1/2)π(5 yd)^2 = 12.5π yd^2 ≈ 39.25 yd^2
__
The shaded region is the difference between these areas:
shaded area = 39.25 yd^2 -25 yd^2 = 14.25 yd^2
A. 79
The inscribed angle is always 1/2 of the arc.
In this case angle RST is the inscribed angle and arc RT is the arc
The arc is 158
Inscribed angle=.5arc
Inscribed angle=.5(158)
Inscribed angle=79
Answer:
angle CAB=37° angle ABC=82°
