Amanda’s Training Continues…..Amanda is training to run a marathon. She must follow a strict schedule to make sure she is ready
Paladinen [302]

Based on her on training regiment, Amanda will be able to run 26 miles in the 25th week.

<h3 /><h3>What is the total number of miles Amanda will run every week?</h3>

Amanda will run 2 miles in the first week and then 1 less mile in the following week. Then 3 more miles in the week after.

Week 1 - 2 miles

Week 2:

= 2 - 1

= 1 mile

Week 3:

= 1 + 3

= 4 miles

Week 4:

= 4 - 1

= 3 miles

Week 5:

= 3 + 3

= 6 miles

From the given pattern, Amanda increase the number of miles ran by 2 miles every 2 weeks.

The number of miles ran every other week would therefore be:

Week 7 = 8 miles

Week 9 = 10 miles

Week 11 = 12 miles

Week 15 = 16 miles

Week 19 = 20 miles

Week 25 = 26 miles

In conclusion, she would reach her goal in 25 weeks.

Solve for x. Round to the nearest tenth, if necessary.
Igoryamba

Answer: 33.2

Step-by-step explanation:

Given

CE=85

\angle C=67^{\circ}

In \triangle CDE, using trigonometry

\Rightarrow \cos 67^{\circ}=\dfrac{CD}{CE}\\\\\Rightarrow CD=CE\cos 67^{\circ}\\\\\Rightarrow CD=85\times \cos 67^{\circ}\\\\\Rightarrow CD=33.2

How many units of a 10% solution are needed to prepare 500 units of a 2% solution?
Akimi4 [234]
First find how many units of solution there is:

500* 2% = 500(.02) = 10 units

You need 10 units of solution in 'x' units of a 10% solution.

x*10% = 0.1x = 10 units   ----->  x = 10/0.1 = 100

100 units are needed
