A cone with a height of 50 meters has a volume of 5400π meters cubed. What is the radius of the cone?

disa [49]

Answer:

r = 18m

Step-by-step explanation:

h = 50 m

Volume of cone = 5400π m³

$\frac{1}{3}\pi r^{2}h=5400\pi \\\\\\\frac{1}{3}\pi r^{2}*50=5400\pi \\\\\\r^{2}=\frac{5400* \pi *3 }{\pi * 50}\\\\\\r^{2}=108*3\\\\r^{2} = 324\\\\\\r=\sqrt{324}\\\\\\$

r = 18 m

If you purchase a dozen bagels, you save 10%. If a dozen bagels originally costs $11.50, what is the sale price

ziro4ka [17]

The sale price is $ 10.35

10% of 11.5 is 1.15
(10/100 = x/11.5)

11.5-1.15 = 10.35!

Missing Details

Quarters ≡ Dimes ≡ Nickels ≡ Pennies

23 ≡ 29 ≡ 17 ≡ 38

Answer:

$P(Q\ or\ P) = 0.5701$

Step-by-step explanation:

Given

$Quarters = 23$

$Dimes = 29$

$Nickels = 17$

$Pennies = 38$

First, we calculate total number of coins

$Total = 23 + 29 + 17 + 38$

$Total = 107$

The probability of obtaining quarter (Q) of penny (P) is:

$P(Q\ or\ P) = P(Quarters) + P(Pennies)$

$P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}$

Take LCM

$P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}$

$P(Q\ or\ P) = \frac{23 + 38}{107}$

$P(Q\ or\ P) = \frac{61}{107}$

$P(Q\ or\ P) = 0.5701$

What is 1+1×80+5-23+456×47+56784-2647= Put the answer in Standard form

slamgirl [31]

Answer:

$7.5632 *10^{4}$

Step-by-step explanation:The simplification

1+1×80+5-23+456×47+56784-2647

=1+80+5−23+(456)(47)+56784−2647

=81+5−23+(456)(47)+56784−2647

=86−23+(456)(47)+56784−2647

=63+(456)(47)+56784−2647

=63+21432+56784−2647

=21495+56784−2647

=78279−2647

=75632

Converting 75632 into standard form $7.5632 *10^{4}$
