Answer:

Step-by-step explanation:

hello :

2x+3y=6

1) x = 0 : 2(0)+3y=6 means 3y=6 so : y=6/3 = 2

2) y = 0 : 2x+3(0)=6 means 2x=6 so : y=6/2 = 3

3) x = - 3 : 2(-3)+3y=6 means 3y=12 so : y=12/3 = 4

a rectangular pyramid has a volume of 190 cubic centimeters. Find two possible sets of measurements for the base area and height

DerKrebs [107]

<h3>One possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively</h3><h3>Other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively</h3>

Solution:

The volume of rectangular pyramid is given as:

$Volume = \frac{1}{3} \times base\ area \times height$

Given that,

Rectangular pyramid has a volume of 190 cubic centimeters

$190= \frac{1}{3} \times base\ area \times height$

Substitute, base area = 570 and height = 1

Then we get,

$190 = \frac{1}{3} \times 570 \times 1\\\\190 = 190$

Thus one possible set for the base area and height of the pyramid is 570 cm and 1 cm respectively

Substitute, base area = 285 and height = 2

$190 = \frac{1}{3} \times 285 \times 2\\\\190 = \frac{1}{3} \times 570\\\\190 = 190$

Thus other possible set for the base area and height of the pyramid is 285 cm and 2 cm respectively

DerKrebs [107]

-4.08 is greater than -4.7 since its negative
ex: -1 is greater than -2 since -1 is closer to zero than -2

Ratling [72]

Answer:

rose$7 shrub $11

Step-by-step explanation:

5r+3s=68

1r+14s=161

I will multiply the second by -5 to eliminate r variable

5r+ 3s= 68

-5r- 70s = -805

-67s = -737

Divide both by -67

s= 11

14*11=154

161-154 =7

5*7 + 3*11 = 68

35+33 = 68

7+ 14*11 = 161

7+154 = 161
