sukhopar [10]

Answer:

Step-by-step explanation:

x + 3 : x + 8 : : 2 : 3

(x + 3) \times 3 = (x + 8) \times 2 \\ 3x + 9 = 2x + 16 \\ 3x - 2x = 16 - 9 \\ x = 7 \\ x + 3 = 7 + 3 = 10 \\ x + 8 = 7 + 8 = 15 \\

10 : 15

The volume of a gas varies inversely as the pressure upon it. If the volume of the gas is 160 cubic centimeters at a pressure of

erica [24]

Answer:

The new volume is $198.62\ cm^3$ .

Step-by-step explanation:

We are given with the volume of a gas varies inversely as the pressure upon it.

Initial volume is 160 cubic centimetres and initial pressure is 108 Pa. It is required to find the volume when the pressure is 87 centimetres.

According to given condition,

$V\propto \dfrac{1}{P}$

$P_1V_1=P_2V_2$

$V_2$ is new volume

$V_2=\dfrac{P_1V_1}{P_1}\\\\V_2=\dfrac{160\times 108}{87}\\\\V_2=198.62\ cm^3$

So, the new volume is $198.62\ cm^3$ .

What is the equation of the line perpendicular to 2x − 5y = −35 that contains the point (10, 4)?

Gnoma [55]

Perpendicular has slope that multiplies to -1 in other sloope

thsi one

2x-5y=-35
-5y=-2x-35
y=2/5x+7
slope=2/5
2/5 times -5/2=-1
y=-5/2x+b
findn b
(10,4)
(x,y)
4=-5/2(10)+b
4=-25+b
21=b
y=-5/2x+21
2y=-5x+42
5x+2y=42
