kathryn bought an aquarium to replace her fishbowl.The directions for the aquarium say that it should be filled with 9 cubic fee
lesya [120]

The water should fill the aquarium to 1.5 feet

Solution:

Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.

This means volume of aquarium is 9 cubic feet

Given that aquarium is 2 feet wide and 3 feet long

To find: Height of aquarium

Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula

<em><u>The volume of cuboid is given as:</u></em>

volume of cuboid = l \times w \times h

Where "l" is the length

w is the width

"h" is the height

Substituting the values, we get,

9 = 3 \times 2 \times h\\\\9 = 6 \times h\\\\h = \frac{9}{6} = 1.5

Thus the height of aquarium is 1.5 feet

What is an equation of the line that passes through the point (3,-1) and is parallel to the line 5x+3y=6
777dan777 [17]

Answer:

y=-\frac{5}{3} x+4

Step-by-step explanation:

Since the line we are trying to study is parallel to the one given by the standard equation 5x + 3y = 6, it needs to have the same slope as this given line has. Let's write then this equation in slope-intercept so we can find what the slope is :

5x+3y=6\\3y=-5x+6\\y=-\frac{5}{3} x+\frac{6}{3} \\y=-\frac{5}{3} x+2

Then the slope of our line must also be "-5/3" in order to be parallel to the given line.

Now, since we also know a point (3, -1) through which the new line should go, we use the point-slope form of a line:

y-y_0=m(x-x_0)\\y-(-1)=-\frac{5}{3} (x-3)\\y+1=-\frac{5}{3} x+5\\y=-\frac{5}{3} x+4

Leslie can buy her dog's food at Petco for $25 and receive 9 packs with four cans in each. Leslie can buy the same food at Petsm
aniked [119]

Answer:

Leslie should buy her dog food from Petsmart  because the price per can is cheaper

Step-by-step explanation:

Step one;

given data

At Petco, we are told that she receives 9 packs with four cans each for $25

Hence Petco gives a total of 9*4= 36cans

the cost of each can will be 25/36

=$0.69 per can

Step two:

At Petsmart, we are told that she receives 7 packs with six cans each for $25

Hence Petsmart gives a total of 7*6= 42cans

the cost of each can will be 25/42

=$0.59 per can

<u>Leslie should buy her dog food from Petsmart  because the price per can is cheaper </u>
