Answer: The missing length is 40 m.

Step-by-step explanation:

30^2 + b^2 = 50^2

900 + b^2 = 2500

-900 -900

b^2 = 1600

Charmaine, Ravi, and Deon sent a total of 107 text messages over their call phones during the weekend. Ravi sent 7 more messages

galina1969 [7]

Number of messages sent by Charmaine=x=12

Number of text messages sent by Ravi = x+7 = 12+7 = 19

Number of text messages sent by Deon = 4(x+7) = 19*4 = 76

Step-by-step explanation:

Let

x be the number of messages Charmaine sent

Then

Ravi sent 7 more messages than Charmaine = x+7

Deon sent 4 times as many messages as Ravi = 4(x+7)

In total they sent 107 messages

So,

$x+(x+7)+4(x+7)=107\\x+x+7+4x+28=107\\6x+35=107\\Subtracting\ 35\ from\ both\ sides\\6x+35-35=107-35\\6x=72\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{72}{6}\\x=12$

Number of messages sent by Charmaine=x=12

Number of text messages sent by Ravi = x+7 = 12+7 = 19

Number of text messages sent by Deon = 4(x+7) = 19*4 = 76

Toni’s table is 96 inches in diameter. If she covers her circular table with a table cloth that extends 6 inches over the edge o

viktelen [127]

Answer:

2916π in^2

Step-by-step explanation:

Step one:

given data

initial table diamter= 96in

we are told that the extension is 6 in over the edge

the new diameter is = 96+6+6= 108in

the radius is = 108/2=54in

we added 6 twice because it will be on the two sides of the diameter

Step two:

the expression for the area is

Area= πr^2

Area= π*54^2

Area= 2916π in^2
