Answer: -7.45
The seven stays the same and if you turn it into a percent out of eleven it will be 45% so the answer is -7.45 because the negative stays negative remeber 2 positives makes a negative :)

What are the results of these tasks? =<br> 4x-3=5x-3<br><br> -2x=3x-5
frez [133]

Step-by-step explanation:

I think you are trying to find x, I dunno, but if you are here's the solution.

when trying to find x, your main goal is to shift all x terms to one side.

For the first one

4x-3 = 5x-3

Carry all x terms to one side:

(4x-3)-5x = (5x-3)-5x

4x-5x-3 = -3

Shift all constants (purely just numbers, no x) to the other side

(4x-5x-3)+3 = (-3)+3

4x-5x = 0

-x = 0

x = 0

The second one:

-2x = 3x-5

5x = -5

x = -1

Done, have fun with math!

The partial pressure of carbon dioxide in a mixture is 0.31 atm.
juin [17]

Answer:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and X_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

Step-by-step explanation:

For this case the partial presure of carbon dioxide is given by:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and x_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

HELP!!! URGENT!!! I WILL GIVE BRAINLEIST THING ​
lisov135 [29]

Answer:

Horizontal distance = 0 m and 6 m

Step-by-step explanation:

Height of a rider in a roller coaster has been defined by the equation,

y = \frac{1}{3}x^{2}-2x+8

Here x = rider's horizontal distance from the start of the ride

i). y=\frac{1}{3}x^{2}-2x+8

      =\frac{1}{3}(x^{2}-6x+24)

      =\frac{1}{3}[x^{2}-2(3x)+9-9+24]

      =\frac{1}{3}[(x^{2}-2(3x)+9)+15]

      =\frac{1}{3}[(x-3)^2+15]

      =\frac{1}{3}(x-3)^2+5

ii). Since, the parabolic graph for the given equation opens upwards,

    Vertex of the parabola will be the lowest point of the rider on the roller coaster.

    From the equation,

    Vertex → (3, 5)

    Therefore, minimum height of the rider will be the y-coordinate of the vertex.

    Minimum height of the rider = 5 m

iii). If h = 8 m,

    8=\frac{1}{3}(x-3)^2+5

    3=\frac{1}{3}(x-3)^2

    (x - 3)² = 9

    x = 3 ± 3

    x = 0, 6 m

    Therefore, at 8 m height of the roller coaster, horizontal distance of the rider will be x = 0 and 6 m
