Evan used base-10 blocks to model the product of 3 and 0.51.
Lilit [14]

Base 10 blocks are used to perform arithmetic operations.

To model the product of 3 and 0.51, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>

The expression can be represented as:

\mathbf{3 \times 0.51}

Express 0.51 as 0.5 + 0.01

\mathbf{3 \times 0.51 = 3 \times (0.5 + 0.01)}

  • 0.5 means 5 tenths
  • 0.01 means 1 hundredths
  • 3 means that, the above blocks are needed in three places.

Hence, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>

Brianna makes 18.50 per hour and works on average of 28 hours a week. That means she will have an annual gross income of
blsea [12.9K]

Answer:

Annual gross income = $26,936

Step-by-step explanation:

Given:

Per hour Brianna wages = $18.50

Number of hour per week work = 28 hours

Find:

Annual gross income

Computation:

Number of week in year = 52

Annual gross income = Per hour Brianna wages x Number of hour per week work x Number of week in year

Annual gross income = 18.50 x 28 x 52

Annual gross income = $26,936

BiLo currently has 12-packs of Pepsi on sale for $5.55. Food Lion has a sale on 6-packs of Pepsi for $2.75. Which is the better
Gennadij [26K]
<h2>How to find the cost per can</h2>

To find the cost per can, we can divide the total cost by the number of cans.

\frac{total\ cost}{number\ of\ cans} = cost\ per\ can

<h2>Let's start with BiLo:</h2>

Total cost: $5.55

Number of cans: 12

The cost per can will be:

\frac{total\ cost}{number\ of\ cans} = \frac{5.55}{12} = 0.4625

$0.4625 per can

How about Food Lion?

<h2>Food Lion</h2>

Total cost: $2.75

Number of cans: 6

The cost per can will be:

\frac{total\ cost}{number\ of\ cans} = \frac{2.75}{6} = 0.458333....

Around $0.4583 per can

<h2>Comparing</h2>

BiLo: $0.4625

Food Lion: around $0.4583

As we can see, Food Lion has a better cost per can, as it costs less to buy each can of Pepsi.

Answer: Food Lion has a better cost per can

A homeowner is installing a swimming pool. You have been asked to install a circuit to operate a 600-watt underwater light and a
insens350 [35]

Answer:

The answer is given below

Step-by-step explanation:

The loads in the circuit are continuous duty, so the circuit can only loaded to 80% of its current rating.

Calculate 80% current rating of the circuit breaker.

Icb = [ 80/100] (20 A)

     =  (O.8) (20 A )

     = 16 A

Now we assume that the value of supply voltage is 120 V

Now we will calculate current flows via under water light which will be taken as  Load 1

<em>Ii = </em>500 W/120 V

  = 4.167 A

Current via the circulating pump which will be taken as Load 2 IS 8.5 A

<em>I = </em>load1 + load 2

<em>    = 4.167 A + 8.5 A</em>

<em>   = 12.67 A</em>

The total current in the circuit obtained which is less than the circuit breaker rating current. Therefore, the power can be operated for both the loads.
