The function A=A_oe^{-0.01155x} A = A o e − 0.01155 x models the amount in pounds of a particular radioactive material stored in
vivado [14]

They are essentially asking us to solve:

357=900e^{-0.01155x} \implies\\ \frac{357}{900}=e^{-0.01155x} \implies\\ \ln{\frac{357}{900}}=-0.01155x \implies \\ x\approx 80.1

Solving this equation for x tells us that it will take around 80.1 years for the materials in the vault to reduce to 357 pounds.

What is the probability of spinning a number less than 3 or6
Ipatiy [6.2K]

Answer:

Probability of a dice rolling a number less than 3 is 2/6 = 1/3

Probability of dice spinning a number less than 6 is 5/6

Step-by-step explanation:

Number less than 3:

Chances of no. Being 1 and 2, not including 3, is 1/6 individually.

Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3

Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manag
il63 [147K]
Since 2 cases = $48

÷ 48 by 2 to get the cost of one case of paper

48÷2=$24 per case
and each case has 12 pack of paper

so $24 for 12 packs of paper

180÷12=15, which gives you the number of case you need

15 cases × $24= $360 for 180 packs

Please help me get through this.

The value of x in the first question is 3/7.

The value of y in the second question is 17/22

For the first equation given, the first step is to simplify the numbers in the numerator

5(1 - x) + 3(1 +x)

5 - 5x + 3 + 3x

2 - 2x

The equation becomes

\frac{2 - 2x}{1 - 2x} = 8

Cross multiply

2 - 2x = 8(1 - 2x)

2 - 2x = 8 -16x

Combine similar terms

16x - 2x = 8 - 2

14x = 6

Divide both sides of the equation by 14

x = 6/14

x = 3/7

<em><u>The second question </u></em>

the first step is to simplify the terms in the numerator by combining similar terms

y - 4 + 3y

4y - 4

The second step is to simplify the terms in the denominator by combining similar terms

2y - 3 - 4y

-2y - 3

The equation becomes

\frac{4y - 4}{-2y - 3} = \frac{1}{5}

Cross multiply

20y - 20 = -2y - 3

Combine similar terms

20y + 2y = 20 - 3

22y = 17

Divide both sides of the equation by y

y = 17/22
