the sides of a rectangle are in the ratio 3:2. what is the length h of each side if the perimeter of the rectangle is 30cm?

1 answer:

7 0

An easy way to solve this is to simply multiply the ratio until the 3:2(2) equals 30. We should multiply the 3 and 2 by 3 because that makes the equation 9:6. 9+6=15, which we then multiply by 2 because there are 4 sides.

Using the logic above, we can see that the length is 9 and the width is 6.

ratelena [41]

Let's assume

It started in 2000

so, t=0 in 2000

$P_0=6.4million$

we can use formula

$P(t)=P_0 e^{rt}$

we can plug value

$P(t)=6.4 e^{rt}$

In 2005, the same survey was made and the total amount of gamma ray bursts was 7.3 million

so, at t=2005-2000=5

P(t)=7.3 million

we can plug value and then we can solve for r

$7.3=6.4 e^{r*5}$

$r=0.02632$

now, we can plug back

$P(t)=6.4 e^{0.02632t}$

now, we have

P(t)=1 billion =1000 million

so, we can set it and then we can solve for t

$1000=6.4 e^{0.02632t}$

$t=191.924$

approximately

$t=192$

Year is 2000+192

Jose wants to rewrite 24+9 using the greatest common factor and the distributive property. Which expression should he write?

Reil [10]

First get the factors of 24: 2*2*2*3Then the factors of 9: 3*3 Comparing the factors, the GCF is 3 Then you can rewrite the expression: 3*8 + 3*3 At this point, I'm not sure whether what you mean is really distributive property or not since this case is more of a factoring. 3*(8+3)
