If i= V-1, then which expression is equal to 9i(13i)?<br>F -117<br>H 117<br>G 117i<br>I -117i​
DaniilM [7]

If i= V-1, then -117 expression is equal to 9i(13i)

Step-by-step explanation:

Original problem : 9i(13i)

=> 117i^{2} (Multiply)

=> 117 * -1

=> i^{2} = -1

=> -117

If i= V-1, then -117 expression is equal to 9i(13i)

ValentinkaMS [17]

Step-by-step explanation:

We assume that the advertising rates in this journal for full-page ads is x ($/ad); the rate for half-page ads is y ($/ad).

The revenue for 3 full page ads are: 3x ($)

The revenue for 5 half page ads are: 5y ($)

One issue of a journal has 3 full-page ads and 5 half-page ads, generating $6340.

=> The total revenue for 3 full page and 5 half page ads are $6340

=> 3x + 5y = 6340

The revenue for 4 full page ads are: 4x ($)

The revenue for 4 half page ads are: 4y ($)

One issue of a journal has 4 full-page ads and 4 half-page ads, generating $6625.

=> The total revenue for 4 full page and 4 half page ads are $6625

=> 4x + 4y = 6625 (1)

We have:

+) 3x + 5y = 6340

=> 5y = 6340 - 3x

=> y = (6340 - 3x)/5 = 1268 - 0.6x

Replace <em>y = 1268 - 0.6x </em>into (1), we have:

4x + 4y = 6625

⇔4x + 4(1268 - 0.6x) = 6625

⇔ 4x + 5072 - 2.4x = 6625

⇔ 1.6x = 1553

⇔ x = 1553/1.6 = 970.625

=> y = 1268 - 0.6x = 1268 - 0.6*970.625= 1268 - 582.375 = 685.625

So the advertising rate for full page ads is $970.625, for half-page ads is $685.625

A rectangular prism has a volume of 60 cubic feet. if the length and the width double, and the height remains the same, what wil
WITCHER [35]
By definition, the volume of a rectangular prism is given by:
 V1 = (w) * (l) * (h)
 Where,
 w: width
 l: long
 h: height
 Substituting we have:
 60 = (w) * (l) * (h)
 if the length and the width double, and the height remains the same, we have:
 V2 = (2w) * (2l) * (h)
 Rewriting:
 V2 = 4 * ((w) * (l) * (h))
 V2 = 4 * V1
 Substituting we have:
 V2 = 4 * (60)
 V2 = 240 cubic feet
 Answer:
 
the new volume will be:
 
V2 = 240 cubic feet
