Answer:

Step-by-step explanation:

h=11.4 in

r=5.1 in

v=3.14*r^2*(h/3)

V=3.14*5.1^2*(11.4/3)=3.14*26.01*3.8=310.35

4 teachers share 3 gallons of paint. How much paint does each teacher get?

Elodia [21]

Just divide

3/4 = 0.75

4 teachers, and only 3 gallons of paint
1 less gallon of paint, so each teacher should get less than a whole.

0.75 gallons of paint per teacher

Using the formula for simple interest and the given values, find I. P= $300; r = 8%; t= 6 years; I = ? 1=$0 TrueCar Enter your a

Mashutka [201]

Answer: $144

Step-by-step explanation:

The formula to calculate the simple interest is given by :-

$\text{S.I.}=Prt$

Here, P - Principal amount, r - rate of interest and t is time (Generally in years).

Given : P= $300; r = 8%=0.08 ; t= 6 years

Now, the using the above simple interest formula , we have

$\text{I}=300\times0.08\times6\\\\\Rightarrow\ \text{I}=\$\ 144$

Therefore , the simple interest = $ 144.

A 41 gram sample of a substance that's used to detect explosives has a k-value of 0.1392. Find the substance's half life, in day

-BARSIC- [3]

Answer:

The substance half-life is of 4.98 days.

Step-by-step explanation:

Equation for an amount of a decaying substance:

The equation for the amount of a substance that decay exponentially has the following format:

$A(t) = A(0)e^{-kt}$

In which k is the decay rate, as a decimal.

k-value of 0.1392.

This means that:

$A(t) = A(0)e^{-0.1392t}$

Find the substance's half life, in days.

This is t for which $A(t) = 0.5A(0)$ . So

$A(t) = A(0)e^{-0.1392t}$

$0.5A(0) = A(0)e^{-0.1392t}$

$e^{-0.1392t} = 0.5$

$\ln{e^{-0.1392t}} = \ln{0.5}$

$-0.1392t = \ln{0.5}$

$t = -\frac{\ln{0.5}}{0.1392}$

$t = 4.98$

The substance half-life is of 4.98 days.
