Answer:
600
Step-by-step explanation:
Because the tens digit is less than 5, round down to 600
The top and bottom faces are 3 inches by 3 inches.
Area = 3 in. * 3 in. * 2 = 18 in.^2
The front, back, right, and left faces are 3 in. by 6 in.
Area = 3 in. * 6 in. * 4 = 72 in.^2
Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2
Answer: B. 90 square inches
Answer:
28.125 degrees
Step-by-step explanation:
3/8 of 45 is 16.875
45-16.875=28.125
You have to build an equation to find the answer,
angles in a straight line add upto 180°
so your equation would be,
12x+30°=180°
-30 -30
=12x=150°
÷12 ÷12
=x=12.5°
now find the measures of the angles by using 12.5 as x.
angle EAF= 2x
=2×12.5
=25° degrees
angle DAE= 4x
=4×12.5
=50°degrees
angle CAD=6x
=6×12.5
=75°degrees
check,
30+25+50+75=180°degrees
hope this helps.......
Answer:
18000$
Step-by-step explanation:
Frim the text you have the formula:
V=c-crt
where,
c=30000
r=0.1
t=4
So, new value after 4y:
V=30000-4*0,1*30000=30000-12000=18000
