Answer:

  C.  √52

Step-by-step explanation:

Call the base of the altitude point T. The Pythagorean theorem tells you the square of QT is ...

  QT² +TR² = QR²

  QT² = QR² -TR² = 5² -3² = 25 -9 = 16

It also tells you that PQ satisfies ...

  QT² +TP² = PQ²

  PQ² = 16 +6² = 16 +36 = 52 . . . . . substitute known values

  PQ = √52 . . . . . . . take the square root

Help Dana find the sum 346 421 152
chubhunter [2.5K]
To add and get the sum 
  346   
  421
+152

We start on the ones place 6 + 1 + 2 = 9, the sum of the digits in the ones place is not up to 10, we will not regroup this ones place.

So, basically the answer to 13a is NO.
Since we are not able to regroup the ones place there is no regrouped tens to add, therefore the answer to 13b is also NO.

Next is the tens place, 4 +2 +5 = 11, the sum of the digits in the ones place is up to 10 so we regroup the tens place.

Thus, the answer to 13c is YES.

Since, we regrouped the ones place, we add the regrouped hundred, thus the answer to 13d is YES.

Finally, for the hundred place, 1 + 3 + 4 + 1 = 9

Therefore, the sum of

+  152

A sphere has a radius of 5 inches. What is its volume?
jarptica [38.1K]

Given  ↓

  • Radius of sphere = 5 in
<h3>To Find ↓</h3>
  • The volume of the sphere
<h3>Calculations ↓</h3>

\blue{\boxed{\mathsf{V=\frac{4}{3} \pi r^3}}

↑ formula for volume of a sphere

r = 5 in

Plug in the value of r and solve :

\blue{\boxed{\mathsf{V=\frac{4}{3}\pi (5)^3}}}

Simplify as follows :

\blue{\boxed{\mathsf{V=\frac{4}{3}\pi *125} }}

\blue{\boxed{V=\frac{4}{3} *392.7}}

Final Step :

\blue{\boxed{\pmb{V=523.6\:in\:^3}}
