How do you do this math Question

Answers

Answer 1

Answer: remember
a/b time b/a=1
and
a/b times b=a

and when working with inequalities (> < > <)
flip the sign when dividding or multiplying by a negative number
so < becomes >, > becomes <

(3/5)e>9
multiply both sides by 5/3
e>45/3
e>15

x/-6>5
multiply both sides by -6 don't forget to flip sign
x<-30

Write
45%
as a fraction in simplest form.

Answers

9/20 because you would get it as a decimal first and it would be .45 then put 100 at the end and then reduce and you end up with 9/20

As a fraction it would be 45/100 and in simplest form it is 9/20

7p+8p-12=59 ( find the p)

Answers

Hello, lets solve this!

$\sf 7p+8p-12=59\n\n\sf Add~like~terms}\n\n15p - 12=59\n\nAdd~12~on~both~sides\n\n15p -12 + 12 = 59 + 12\n\n15p = 71\n\nDivide~15~on~both~sides\n\n\boxed{\bf{p = (71)/(15) = 4.73333333}}$

Hope I helped! If you have any other qestions or would like further explantion just let me know!! :)

Combine like terms first.
7p+8p=15p
15p-12=59
Now add 12 from both sides.
15p=71
Now divide both sides by 15.
p=4.7333333333

Hope this helps!

The raidus of circle p the larger circle is 7 times the radius of circle 0 the smaller circle. What is the ratio of the area of circle to the area of circle p?Your choices are: 1 to 7, 7 to 1, 49 to 1 , 1 to 49
plz explain

Answers

since we know that the radius of circle p is 7 times that of the radius of circle o we can say that radius of circle p equals 7x and the radius of circle o is x.
using the area formula we can say that area of circle p equals

The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula mc023-1.jpg. If Saturn’s orbital period is 29.5 years, what is its distance from the sun?

Answers

Given that the orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a^(3/2). If Saturn’s orbital period is 29.5 years, then 29.5 = a^(3/2) a = (29.5)^(2/3) = 9.547 Therefore, Saturn's distance from the sun is 9.547 astronomical units.

The sum of three consecutive even numbers is one hundred sixty - two.What is the smallest of the three numbers ?

Answers

Answer:

Step-by-step explanation:

Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...

x + (x+2) +(x+4) = 162

3x = 156 . . . . . . . . . . . .subtract 6

x = 156/3 = 52

The smallest of the three numbers is 52.

___

I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.
