Answer:

$2.5

Step-by-step explanation:

Number of pounds of banana needed = 5 pounds

Cost per pound of banana = 0.50

To solve using place value blocks :

Ignoring the decimal in the cost per pound:

We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.

5 * 5 = $25

Now we can add the one decimal point (in the cost per pound) to our result

Then we have $2.5

Hence, total cost = $2.5

A satellite is composed of 30 modular units, each of which is equipped with a set of sensors, some of which have been upgraded.

Anit [1.1K]

Answer:

$\frac{1}{7}$

Step-by-step explanation:

The satellite has 30 modular units.

There are equal numbers of non-upgraded sensors in each unit.

Let us assume that on the entire satellite there are x numbers of upgraded sensors.

Then as per the given condition, there are $\frac{x}{5}$ number of non-upgraded sensors in one unit.

Therefore, the number of non-upgraded sensors on the entire satellite is $\frac{30x}{5}$ =6x

Hence, total number of sensors in the satellite is (x+ 6x) =7x

Therefore, the required fraction of the upgraded sensors is $\frac{x}{7x} =\frac{1}{7}$ . (Answer)
