65 miles per hour means that for each hour, it goes 65 miles

65 miles*2 hours= 130 miles

Final answer: 130 miles

If it travels 65 miles for on hour, you just need to double that amount to get 2 hours, so 65+65 is 130. 130 miles in 2 hours.

Answer:

8.06

Step-by-step explanation:

Use the Pythagorean theorem:

$a^{2} +b^{2} =c^{2}$

The hypotenuse is always the slanted side, or c (x in this picture), but the other numbers can be interchanged. Doesn't matter.

Plug the numbers 4 and 7 into the formula.

$4^{2} +7^{2} =c^{2} \\$

Now evaluate them to get $c^2$

16+49=65

To get c, take the square root of 65

$\sqrt{65} = 8.06$

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)
