2.5 g converted to kg:  2.5 g x 1 kg/1000 g = 0.0025 kg = 2.5x10-3 kg

cm3 converted to m3:  1 cm3 x 10-6 m3/cm3 = 1x10-6 m3

Thus, the conversion of 2.5 g/cm3 to kg/m3 would be 2.5x10-3 kg/10-6 m3 = 2.5x103 kg/m3 = <u>2500 kg/m3</u>

1 x - 37 =- 84<br> Solve please
MAXImum [283]

Answer:

Hello there!

You question is

1x - 37 = -84

am i right?

Your answer is :

<h2>x = - 47</h2>

Step-by-step explanation:

So, since 1x and x are basically the same, you don't really have to do anything with that.

You add 37 on both sides.

Therefore, your answer is x = -47.

Hope this helps!

(Note: if there are more instructions to this question, please let me know.) :)

Which of the following is a zero does the function f (x) =(x+3) (x-7) (x+5)
Over [174]

Answer:

x=-3

Step-by-step explanation:

(x + 3)

x+3=0

-3 -3

x= -3

opposite of addition would be subtraction. since your trying to solve for x You want to get x alone and you subtract by 3 on both sides which would cancel the 3 on the left, leaving:

x =  - 3

if you follow the same process on all of them you come to the conclusion that only -3 is a zero in the options listed.

NOTE: When you become more experienced whenever you see expressions like that you'll come to realize that the zero is the opposite sign of the number if it's just x- or x+ a number.

example:

(x - 40)

it'll be the opposite sign so since it's a negative the zero of that would be positive 40.

hope this helps!

Mickey's bowling score is 16 less
Tpy6a [65]

Mickey's bowling score is 167 and Minnie's bowling score is 61

Step-by-step explanation:

The given is:

1. Mickey's bowling score is 16 less  than 3 times Minnie's score

2. The  sum of their scores is 228

We need to find the score of each one

Assume that the score of Minnie is x

∵ Minnie's score = x

∵ Mickey's score is 16 less  than 3 times Minnie's score

- That means subtract 16 from 3 times Minnie's score

∴ Mickey's score = 3 x - 16

∵ The sum of their scores is 228

- Add their scores and equate the sum by 228

∴ x + 3 x - 16 = 228

- Add like terms in the left hand side

∴ 4 x - 16 = 228

- Add 16 for both sides

∴ 4 x = 244

- Divide both sides by 4

∴ x = 61

Substitute the value of x to find their scores

∵ Minnie's score is x

∴ Minnie's score = 61

∵ Mickey's score is 3 x - 16

∴ Mickey's score = 3(61) - 16 = 167

Mickey's bowling score is 167 and Minnie's bowling score is 61

Solve (factorise ).<br>​
Slav-nsk [51]

Answer: (1)  x²y (2) 7pqr  (3) a  (4) 6a²  (5) y³z²

Step-by-step explanation:

(1)  x^4y³ and x²y

     x^4y³ =  x²y(x²y²)

    x²y      = x²y

Therefore the Highest Common factor

               x²y which is the common factor.

(2) 14p²qr^4 = 2 x 7 x p² x q  x r^4

   49p²q²r    = 7 x 7 x p² x q² x r

   35pqr       = 5 x 7 x p x q x r

Therefore HCF =  7 x p x q x r

                         = 7pqr

(3) -a^5             = -( a x a x a x a x a )

                         = -(a^5)

       ab³            =   a x b x b x b

Therefore HCF =   a

(4)   6a²             = 2 x 3 x a x a

      -18a6          = -( 2 x3 x 3 x a x a x a x a x a x a)

     -12a²            = -( 2 x 2 x 3 x a x a )

Therefore HCF  = 2 x 3 x a²

                          = 6a²

(5)   3y³z²           = 3 x y x y x y x z x z , 3 x y³ x z²

      15y^4z²       =  3 x 5 x y x y x y x y x y x z x z, 3 x 5 x y^4 x z²

      y^6z³          = y^6 x z³

Therfore HCF  = y³ x z²

                         = y³z²

6^2 + 20.1^2 =? 22.9^2
36 + 404 does NOT equal 524.41
These do NOT form a right triangle.

10.5^2 + 20.8^2 =? 23.3^2
110.25 + 432.64 = 542.89
Therefore, it is a right triangle.
