Answer: B. $T=B-3$

Step-by-step explanation:

Let T represents the age of Ty and B represents the age of Bea.

The given statement : Ty is 3 years younger than Bea.

In algebraic form the above statement can be written as

$T=B-3$

Therefore , the equation represents the given relationship is:

$T=B-3$

Therefore , B is the correct answer.

The average attendance at school for 5 days was 264. If the attendance on the 5th day was 256, calculate the average attendance

Tema [17]

Answer:

266

Step-by-step explanation:

Let the attendence of 5days be a,b,c,d,e

given,

(a+b+c+d+e)/5=264

a+b+c+d+256=264*5 [since 5th day=256]

(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]

average attendence of 4 days =266

What is the volume of the hemisphere? 583.2cm^3cm 3 291.6cm^3cm 3 6882.3cm^3cm 3 3441.1cm^3cm 3 Item at position 3

Sveta_85 [38]

Answer:

See Explanation

Step-by-step explanation:

The question has missing details; as the radius or an attachment of the hemisphere is not given.

However, I'll solve on a general terms.

The volume of a hemisphere is: $V = \frac{2}{3}\pi r^3$

Take for instance

$r = 14.9cm$

The volume becomes:

$V = \frac{2}{3} * 3.142 * 14.9^3$

$V = \frac{2 * 3.142 * 14.9^3}{3}$

$V = \frac{20787.151516}{3}$

$V = 6929.051cm^3$

<em>So, all you need to do is plug in the value of radius in the formula.</em>

The RideEm Bicycles factory can produce 170 bicycles in a day at a total cost of $10,900. It can produce 190 bicycles in a day a

KatRina [158]

If we assume that when producing 190 bicycles vs 170 bicycles the difference in total daily cost is purely attributed to the extra 20 bicycles, THEN the cost to produce 20 bicycles (190 - 170) = 11600 - 10900 = 700

So the cost per bicycle is 700/20 = 35/bike

Now we can subtract the cost of bicycle production to determine the daily fixed cost that is not related to the number of bicycles.

i.e. 170 bicycles x 35 = 5950

So on a day that RideEm produces 170 bicycles, subtract 5950 from total day cost of 10900, which equals 4950.

So the fixed daily costs are $4950, and on top of this, the company pays 35/bike to produce.
