Answer:

Cara multiplied only 4 and 7 together and did not multiply 4 and 13.

Step-by-step explanation:

She didn't distribute the 4 to both numbers inside the parenthesis. If she had done so, she would have gotten 28 - 42, <em>not</em> 28 - 13.

The radius,r , of a sphere is 4 . 3m Calculate the sphere's volume,v . Use the value 3.14 for sqaure, and round your answer to t
kotykmax [81]

Answer:

V(s) = 332,9 m³

Step-by-step explanation:

The volume of a sphere is:

V(s) = (4/3)*π*r³

if we know  r  = 4,3 m then

V(s)  = (4/3)*3,14*(4,3)³

V(s)  = 332,8693 m³

Rounding the answer to the nearest tenth

V(s) = 332,9 m³

If x = 5, y = 6, and z= 2, is V x2 + y2 + z2 + 50<br> rational or irrational? Explain.
Bumek [7]

Answer:

irrational

Step-by-step explanation:

because

5² + 6² + 2² + 50 = 25+36+4+50 = 115

and 115 is not a squared integer or rational number, so that sqrt(115) is one of these numbers with infinite digits after the decimal point but without any repeating pattern.

and that is per definition irrational.

If you put a $160 coat on layaway and make a 25% deposit, what is the balance owed?
Anna71 [15]
25% of $160

= (25/100) * 160

= 0.25 * 160

= 40

$40 paid.

Balance owed = $160 - $40 = $120

Balance owed = $120
