42 - ( 42÷2 + 10 ) = 42 - ( 21 + 10 ) = 42 - 31 = 11 cars are silver ;
11 / 42 is the fraction of the cars are silver.

What is the equation of a vertical line passing through the point (-5,-1)
Stels [109]
Learn this :
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number

ok....so u need the equation for a vertical line passing thru (-5,-1)...
a vertical line is represented by x = a number.....and that number will be the x value of ur points.

Therefore, ur equation is : x = -5 <==

**just so u know, if u were needing a horizontal line going thru the same points, ...and a horizontal line is represented by y = a number...with the number being the y value of ur points....the equation would be y = -1

The volume of a cube is 8073 cm3.<br> Work out an estimate for its surface area
Gemiola [76]

Answer:

2414.42 cm^2

Step-by-step explanation:

volume = base x height

and we know that a cube will always have the same length for any side so volume is basically length^3

volume = length^3

8073 = x^3

x = \sqrt[3]{8073}

use a calculator and you get that x = 20.06 cm

Surface area(SA) = 6a^2 (a is area)

a = x^2

so SA = 6(20.06)^2 = 2414.4216 ≈ 2414.42 cm^2

faust18 [17]

Answer:

a. The probability of getting an specific sequence would be

(1/20)*(1/19)*(1/18)*(1/17)*(1/16)

b. The probability  of having an specific sequence would be.

5/20 = 1/4

Step-by-step explanation:

a. If you draw 5 marbles without replacement, the probability of getting an specific sequence would be

(1/20)*(1/19)*(1/18)*(1/17)*(1/16)

b. If you draw 5 marbles all at once without replacement, the probability  of having an specific sequence would be.

5/20 = 1/4

a number consist of 2 digits the digit in tens place is twice unit place the no. formed by reversing the digit is 27 less than o
luda_lava [24]

Answer:

63

Step-by-step explanation:

If x units, then 2x tens

Number is: 2x(10)+x = 21x

Reversing digits:

2x units and x tens,

Number is: x(10)+2x = 12x

21x - 12x = 27

9x = 27

x = 27/9 = 3

Original number: 21x = 21(3) = 63
