A square pyramid with a height of 7 inches has a volume of 47.25 cubic inches. Find the side length of the square base.

Romashka [77]

Answer:

4.5 inches

Step-by-step explanation:

volume= 1/3 (base area) × height

47.25= 1/3 ( base area) × 7

20.25 = base area

now since the base is a square we can evaluate base area = length²

20.25= length²

length = 4.5 inches

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre o

kifflom [539]

Answer:

$792\ \text{pounds}$

Step-by-step explanation:

$x_1=70$ cubic feet of fertilizer is used in $y_1=770$ pounds of strawberries

$x_2=90$ cubic feet of fertilizer is used in $y_2=990$ pounds of strawberries

$x=72$ cubic feet of fertilizer is used

Linear interpolation is applied

$y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}$

72 cubic feet of fertilizer will yield $792\ \text{pounds}$ of strawberries.

Find the present balance.

Triss [41]

<h3>Credited balance:-</h3>

$\\ \rm\longmapsto 115.90+115.90+345.85$

$\\ \rm\longmapsto 231.80+345.85$

$\\ \rm\longmapsto 577.65$

<h3>Debited amount:-</h3>

$\\ \rm\longmapsto 25.85+2.00$

$\\ \rm\longmapsto 27.85$

<h3>Checked amount:-</h3>

$\\ \rm\longmapsto 19.45+21.02+95.98$

$\\ \rm\longmapsto 117+19.45$

$\\ \rm\longmapsto 136.45$

<h3>Total change in balance</h3>

$\\ \rm\longmapsto 577.65-(27.85+136.45)$

$\\ \rm\longmapsto 577.65-191.3$

$\\ \rm\longmapsto 386.35$

Now

<h3>Current balance</h3>

$\\ \rm\longmapsto 386.35+271.31$

$\\ \rm\longmapsto\$ 657.66$
