The price of Stock A at 9 AM. was $13.38. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $14.13. It begins to decrease at the rate of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?

Answer:

[tex]15.38 \times {10}^{ - 2} = 0.1538[/tex]

I hope I helped you^_^

15.38x10^-2 isn't proper scientific notation.

The coefficient must be between 1 and 10.

Proper scientific notation would be

1.538 x 10^-1

Convert into standard form:

0.5138 is our answer.

And we're done!

Hope it helps you! :)

Answer:

x is -7.5  or -4.5

Answer:

A, E, and D

Step-by-step explanation:

Answer: x=50

how?

[tex]\frac{x}{2}[/tex] - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:

[tex]\frac{x}{2}[/tex]=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)

25 x 2= 50

therefor the x=50

Answer:

4m

Step-by-step explanation:

First subtract:

9m-7m=2m

Then add:

2m+2m= 4m

Hope this helps!

Answer:

it would have tobe the forst option but iy has to be written 11.7 × 10^4

The answer is 28/3, and in simplest form its 9 1/3

Answer: 2l+2w=48

Subtract 2w from both sides.

2l=48−2w

Divide both sides by 2.

2

2l

​

=  

2

48−2w

​

Dividing by 2 undoes the multiplication by 2.

l=  

2

48−2w

Divide 48−2w by 2.

l=24−w

Answer:

14centimeters

Step-by-step explanation:

from our equation,

2l + 2w = 48

we know that the width = 10cm

so,

2l + 2( 10 ) = 48

2l + 20 = 48

2l = 48 - 20

2l = 28

divide through by 2

2l / 2 = 28 / 2

l = 14

therefore,

l = 14 centimeters

Now, she plans to buy w outfits which cost $75.88 each.

The inequality for this is:

Solving this we get:

w = 1 is the only integer solution greater than zero

Answer:

-1

Step-by-step explanation:

Let's take two points on the line- (0,2) and (2,0).

To find the slope:

[tex]m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{0 - 2}{2-0}\\m = \frac{-2}{2}\\m = -1[/tex]

The slope is -1.

Answer: [tex]\sqrt{11[/tex]

Step-by-step explanation: pythagorean theorem a^2 + b^2 =c^2

switch it to c^2 - b^2 = a^2

c=6 and b=5

(6)^2 - (5)^2 = 36-25 which is 11

11=c^2. to find c, square root 11. the simplest form for this is just [tex]\sqrt{11[/tex]

Answer:

Answer:

x-intercept is (40/7, 0) and y-intercept is (0, 5)

Step-by-step explanation:

x-intercept ==> y-coordinate is 0 ==> y=0

y-intercept ==> x-coordinate is 0 ==> x=0

because the function is 7x + 8y = 40

when y = 0 ==> 7x = 40 ==> x = 40/7

so the x-intercept is (40/7, 0)

when x = 0 ==> 8y = 40 ==> y = 5

so the y-intercept is (0,5)

Answer:

The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.

Answer:

Total weigh = 75g

a) so the mass of wheat and oats one protion = 75*(71/100) g = 53.25g

b) the mass of nuts in one serving = 75*(2.5/100) g = 1.875g

Step-by-step explanation:

Here I think mass = weigh, as it's not physics.

Answer:

The selling price is $17.40

Step-by-step explanation:

x = selling price

x = 12 + 0.45(12)

x = 12 + 5.4

x = 17.4

The final selling price is $17.40.

Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.

Answer:

$17.40

Step-by-step explanation

Find what 45% of 12 is.

You can do this by multiplying 0.45 by 12 which is 5.4

Then you just add 5.4 to 12 which gives you 17.4  

What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

∴ so the answer is option A

Answer:

m, is equal to (4/3)

Step-by-step explanation:

Match the given equation y =(4/3)x-3 to the standard slope-intercept form y = mx + b.  By doing so we see that the slope, m, is equal to (4/3).
