9514 1404 393

Answer:

  24

Step-by-step explanation:

If 7/15 are fond of cricket, the remaining number is 1 -7/15 = 8/15 of the class. The number of students in the class is ...

25 + 20 = 45

so 8/15 of the class is ...

  (8/15)(45) = 8(45/15) = 8(3) = 24

24 students are fond of football.

In rectangle JKLM, angle JML is 3x - 15. Find the value of x.
S_A_V [24]
All angles of a rectangle are right angles.
Right angles measure up to 90 degrees.
JML is also a right angle which means 3x - 15 is equal to 90

3x - 15 = 90
3x = 105
x = 35

An aquarium has a length of n^ 2 +2 inches, a height of n + 5 inches, and a width of 10 inches. What is the volume, in cubic inc
kodGreya [7K]

The formula of a volume of a rectangle prism:

V=lwh

l - length

w - width

h - height

We have

l=n^2+2;\ w = 10,\ h=n+5

Substitute:

V=(n^2+2)(10)(n+5)=(10n^2+20)(n+5)\\\\=(10n^2)(n)+(10n^2)(5)+(20)(n)+(20)(5)\\\\=10n^3+50n^2+20n+100

<h3>Answer: V = (10n³ + 50n² + 20n + 100) in³</h3>
