1+d
Step-by-step explanation:
2+2-4
4-3=1
Now your left with 1+d
So 1+d, is your final answer
Answer:
1386 in³
Step-by-step explanation:
Volume of the composite cone = volume of a hemisphere + volume of a cone
=>Find the volume of cone
Volume of cone = ⅓πr²h
π = 3.142
r = 7 in
h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]
h = √(225 - 49)
h = √176 ≈ 13 in
Volume of cone = ⅓*3.142*7²*13
= ⅓*2001.454 ≈ 667 in³
=>Find volume of hemisphere.
Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³
π = 3.142
r = 7 in
Volume = ⅔*3.142*7³ ≈ 719 in³
<em>Volume of composite figure = 667+719 = 1386 in³</em>
Answer:
x=-6 y=7
Step-by-step explanation:
8x+5y=-13; x+y=1
Isolate x and substitute
(-13-5y)/8 +y=1
Isolate y
y=7
substitute y=7
(-13-5*7)/8=-6
A.place the point of compass on point b
if there's 3 counselors / 45 students.
3 counselors / 45 students = 1 counselor / 15 student
10 counselors multiplied by 15 students = 150 maximum students allowed.
Tanya paints 55 ft^2 / 30mins.
60 mins = 1 hour
60 mins / 30 mins = 2
55 multiplied by 2 = 110
(There were two different people mentioned in the problem)
Tanya, or Angela, paints 110 square feet every hour.
