Mystery number: The number is less than 190000 and greater than 180000.

Kipish [7]

The answer to it is
180, 000 <n> 190, 000
180,000 + 2000 = n = 5000-187, 000
182,000 = n = 182, 000
Or,
180, 000 <n> 190,000
n + 5000= 187, 000                           n – 2000 = 180, 000
n= 187, 000- 5000             n = 180, 000 + 2000
n= 182, 000                                       n= 182, 000

The formula for the volume of a right circular cone, V, is given below, where r represents the radius of the base of the cone an

Mrrafil [7]

Answer:

$r=\sqrt{\frac{3V}{(\pi h)}}$

Step-by-step explanation:

we know that

The volume of a right circular cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height

Solve for r-----> That means, isolate the variable r

step 1

Multiply by 3 both sides

$3V=\pi r^{2}h$

step 2

Divide by $(\pi h)$ both sides

$\frac{3V}{(\pi h)}=r^{2}$

step 3

take square root boot sides

$r=\sqrt{\frac{3V}{(\pi h)}}$

At the city museum, child admission is $5.70 and adult admission is $9.80 . On Sunday, four times as many adult tickets as child

Ket [755]

5.70c + 9.80a = 1526.60
a = 4c

5.70c + 9.80(4c) = 1526.60
5.70c + 39.20c = 1526.60
44.90c = 1526.60
c = 1526.60/44.90
c = 34 <=== child tickets sold

a = 4c
a = 4(34)
a = 136 ...adult tickets sold
