Answer:

Greater than symbol.

2/3 > 2/4

Step-by-step explanation:

We have two fractions, 2/3 and 2/4

We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).

Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.

2/3 and 2/4

With 2/3 being greater than 2/4.

2/3 = 0.67

2/4 = 0.50

Succinctly, 2/3 > 2/4.

Question 4 (Fill-In-The-Blank Worth 6 points)

Marrrta [24]

The formula for density of an object is Density= $\frac{mass}{volume}$ First you plug in the information you already know. 163.5= $\frac{mass}{0.492}$ Now you have to solve for the mass so you multiply 0.492 by 163.5 $0.492*163.5=80.442$ Lastly, you simplify and you will get 80.44. Hope this helped :)

Multiply 3/7 by the reciprocal of -3/14

Alexandra [31]

Multiplying 3/7 by the reciprocal of -3/14,

$\frac{3}{7} \times \frac{14}{ - 3} \\ = \frac{1}{1} \times \frac{2}{ - 1} \\ = \frac{2}{ - 1} \\ = - 2$

Hope it helps!!

Question 5: How long will it take for 2 g of a sample of iodine-131, which has a half-life of about 8 days, to decay to 0.04 g?

Aleonysh [2.5K]

This problem can be represented through the following equation

A = A₀(1/2)^t/h

where

A-----------> is the amount of substance left after time t

A₀ ----------> is the original amount---------> 2 g

h-------------> is the half-life-----------> 8 days

for A=0.04 g

t=?

0.04 = 2(1/2)^t/8

0.02 = (1/2)^t/8

Take ln on both sides:

ln(0.02) = ln [(1/2)^t/8]

ln(0.02) = (t/8)(ln 1/2)

t = 8*ln(0.02)/ln(1/2)

t = 45.15 days

the answer is 45.15 days
