joja [24]

Answer:

Step-by-step explanation:

A bag contains 8 red marbles, 3 blue marbles and 7 green marbles.

Total = 18 marbles.

Probability of drawing three red marbles = probability of drawing one red without replacement + probab of drawing another without reeplacement + probab of drawing a third without replacement.

Probability of drawing three red marbles = 8/18 + 7/17 + 6/16 = 0.4444 + 0.4118 + 0.3750 = 1.2312.

The product of two consecutive square numbers is 144. Work out the two numbers
Sergio [31]

Let the first number be = x

Let the second number which is consecutive be = x+1

As given, the product of two consecutive square numbers is 144

x^{2}*(x+1)^{2}=144

Square rooting both sides we get

x(x+1)=12

x^{2}+x=12

x^{2}+x-12=0

x(x+4)-3(x+4)=0

(x-3)(x+4)=0

x=3 or x=-4

Neglect the negative value so we get x=3

Hence, one number is 3 and the consecutive number is = 3+1=4

The square of the numbers are 9 and 16.

Three fourths of x increased by 5 is - 7​
Finger [1]

Answer:

x=\frac{8}{3}

Step-by-step explanation:

\frac{3}{4} x+5=7

Subtract 5 from both sides.

\frac{3}{4}x+5-5=7-5

Simplify.

\frac{3}{4}x=2

Multiply both sides by 4.

4*\frac{3}{4} x=2*4

Simplify.

3x=8

Divide both sides by 3.

\frac{3x}{3} =\frac{8}{3}

Simplify.

x=\frac{8}{3}
