Write 600 as a product of it's primse factors

givi [52]

Answer:

2*2*2*3*5*5

2^3 *3* 5^2

Step-by-step explanation:

600 = 60*10

These are not prime so keep going, breaking 60 and 10 down

= 6*10 * 5*2

6 and 10 are not prime so keep going ( 5 and 2 are prime)

= 3*2 * 5*2 * 5*2

All of the numbers are prime, so we normally write them in order from smallest to largest

2*2*2*3*5*5

We can write with exponents

2^3 *3* 5^2

A prop for a school play is a sphere that will be hung from the ceiling. The surface area of the sphere is 5 024 cm'. If the sur

denis23 [38]

Answer:

The radius of the sphere, to the nearest cm:

$r\approx 20$ cm

Step-by-step explanation:

The surface area of a sphere is given by the formula

A = 4πr²

where r is the radius of the sphere.

Given

The surface area of sphere A = 5024 cm²

The radius of the sphere can be determined such as

$A\:=\:4\pi r^2$

$r\:=\:\frac{1}{2}\sqrt{\frac{A}{\pi }}$

Plug in Surface Area of sphere = 5024, π = 3.14 in the formula

$\:r\:=\:\frac{1}{2}\sqrt{\frac{5024}{3.14}}\:\:$

$r\approx 20$ cm

Therefore, the radius of the sphere, to the nearest cm:

$r\approx 20$ cm

Three friends decide that they each want to be able to buy a new bike in four years.IIiana puts $500 in a savings account with a

Lisa [10]

Answer:

Iliana will have the most money, with a total of $580

Step-by-step explanation:

We can find the amount of money that each one will have using the formulas of interest:

For Iliana and Joann, simple interest: Total money = P + P*r*t

For Cyndy, compound interest: Total money = P*(1+r)^t

So, using the time of four years, we can calculate the total money of each one:

Iliana: P = 500 and r = 0.04:

Total money = 500 + 500*0.04*4 = $580

Joann: P = 515 and r = 0.03:

Total money = 515 + 515*0.03*4 = $576.8

Cyndy: P = 500 and r = 0.035:

Total money = 500*(1+0.035)^4 = $573.7615

So Iliana will have the most money, with a total of $580
