Original: $100, Discount: 13%

Answer:

The 26% solution should she use is explained below in detailed explanation.

Step-by-step explanation:

Assumed there be 10 percent of x liters of acid solution

Assumed there be 26 percent of y liters of acid solution

provided Information

A chemist needed to combine a 10 percent acid solution with a 26 percent acid solution to obtain 16 liters of a 14 percent acid solution

So, ( 10 / 100 )*x + ( 26 / 100 )*y = ( 14 / 100 )*16

=> 0.1*x + 0.26*y = 0.14*16

=> 0.1*x + 0.26*y = 2.24 ....................... eq 1

x + y = 16 ......................... eq 2

Multiply ( 0.1 ) in both side in eq 2

=> 0.1*x + 0.1*y = 0.1*16

=> 0.1*x + 0.1*y = 1.6 ......................... eq 3

Subtract eq 3 from eq 1

0.1*x - 0.1*x + 0.26*y - 0.1*y = 2.24 - 1.6

=> 0.16*y = 0.64

=> x = 0.64 / 0.16

=> y = 4

So, 4 liters of 26% solution she should utilized

If the first term is 5 and the common ratio is 6 then the fourth term of the sequence be 1080.

Given that the first term is 5 and the common ratio is 6.

We are told to find the fourth term of the sequence.

Because there is common ratio of the sequence so the given sequence is a geometric progression.

A geometric progression is basically the sequence in which each term is varied by another by a common ratio.

Nth term of GP=a[tex]r^{n-1}[/tex]

4th term is first term is 5 and the common ratio is 6=5*[tex]6^{4-1}[/tex]

=5*[tex]6^{3}[/tex]

=5*216

=1080

Hence if the first term is 5 and the common ratio is 6 then the fourth term of the sequence be 1080.

I hope this helps!!

The area of the rectangular room would be 84 square meters.

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

A rectangular room that is 9 3/5 meters long and 8 3/4 meters wide

According to the given question, we can write the dimension as:

The width of the room = 8 3/4 meters = 35/4 meters

The length of the room = 9 3/5 meters = 48/5 meters

The area of the room = width of the room ×  length of the room

The area of the room = 35/4 × 48/5

Apply the multiplication operation,

The area of the room = 84 square meters

Therefore, the area of the room is 84 square meters.

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Answer:

The equation that models her distance from home, y, as a function of time, x will be:

Step-by-step explanation:

We know that the slope-intercept form of a linear function is

y = mx+b

Here m is the slope and b is the y-intercept

Given that Aniyah is driving home at a constant speed.

at t = 20 minutes, she has covered 70 miles

so the rate of change = 70/20

                                     = 3.5 miles per minute

Finding the y-intercept by substituting m = rate of change = 3.5 and the point (20, 70)

y = mx+b

70 = 3.5(20) + b

b = 70 - 70

  = 0

Thus, the equation becomes

y = mx+b

y = 3.5x + 0

y = 3.5x

Therefore, the equation that models her distance from home, y, as a function of time, x will be:

Answer:

[tex]|z| = 27[/tex] -- Modulus

[tex]\theta = \frac{\pi}{3}[/tex] --- Argument

Step-by-step explanation:

Given

[tex]((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]

Required

Determine the modulus and the argument

We have that:

[tex]z = ((\sqrt 3)(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18}))^6[/tex]

Expand:

[tex]z = (\sqrt 3)^6(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]

[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex]

A complex equation can be expressed as:

[tex]z = |z| e^{i\theta}[/tex]

Where

[tex]|z| = modulus[/tex]

[tex]\theta = argument[/tex]

Where

[tex]e^{i\theta} = (cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})[/tex]

So:

[tex]z = 27(cos\frac{\pi}{18} + i\ sin\frac{\pi}{18})^6[/tex] becomes

[tex]z = 27(e^{i\frac{\pi}{18}})^6[/tex]

By comparison:

[tex]e^{i\theta} = (e^{i\frac{\pi}{18}})^6[/tex]

This gives:

[tex]{i\theta} = i\frac{\pi}{18}}*6[/tex]

[tex]{i\theta} = i\frac{6\pi}{18}}[/tex]

[tex]{i\theta} = i\frac{\pi}{3}}[/tex]

Divide through by i

[tex]\theta = \frac{\pi}{3}[/tex]

Hence, the modulus, z is:

[tex]|z| = 27[/tex]

And the argument [tex]\theta[/tex] is

[tex]\theta = \frac{\pi}{3}[/tex]

the answer its 44=0

Step-by-step explanation:

18y-6y+22=11(y-2)+y1

We move all terms to the left:

18y-6y+22-(11(y-2)+y1)=0

We add all the numbers together, and all the variables

12y-(11(y-2)+y1)+22=0

We calculate terms in parentheses: -(11(y-2)+y1), so:

11(y-2)+y1

We add all the numbers together, and all the variables

y+11(y-2)

We multiply parentheses

y+11y-22

We add all the numbers together, and all the variables

12y-22

Back to the equation:

-(12y-22)

We get rid of parentheses

12y-12y+22+22=0

We add all the numbers together, and all the variables

44=0

a) Another name for plane Z is LN plane.

b) PHJ and M are distinct points that are collinear.

c) N and K are distinct points that are coplanar.

d) HL and HK are distinct lines that intersect

a) The common point in lines LN and PN  is N and it is the intersection point.

b) Any three non-collinear locations inside a plane can be used to give it a name. Points H, J, and K cannot be combined because an unlimited number of planes cross through them. Think about the flat piece of paper rotating about this axis (like a propeller). We can only build one specific plane if the points are not all along the same line.

I'll choose P, H, and J as the non-collinear points to give the object the name Plane PHJ. There may be other solutions.

c) Because they are on the same line, points H, J, and K are collinear. Fill up the answer box by selecting either H or K. I'll choose point K.

d) Line HK and point P are parallel. Both of them are present on the same flat piece of paper or on the same flat plane.

That flat plane can be compared to the surface of the earth, but point N is located underneath. Therefore, the ground plane and point N wouldn't be coplanar.

Answer: -2 and 4

Step-by-step: You see the horizontal line? now look at the the numbers -2 and 4 on that line. Notice how the line passes through them? those are your x-intercepts.

The required coordinates of the x-intercepts of the parabola are (0, -2) and (0, 4).

The x-intercept is defined as an intercept that is located at the x-axis of the plane, which is the location or coordinates from where the line crosses.

We have to determine the coordinates of x-intercepts and y-intercepts that would function in the given graph.

The parabola of the graph is given in the question

A horizontal axis, or x-axis, and a vertical axis, or y-axis, are present in a 2-dimensional coordinate graph. Intercepts are the points (0, -2) and (0, 4) here lines representing a range of values intersect these axes.

Therefore, the required coordinates of the x-intercepts of the parabola are (0, -2) and (0, 4).
