Answer:

D. 0%

Step-by-step explanation:

The percentage of profit at which one of the products are sold = 30%

The percentage loss at which the other product are sold = 30%

Let x represent the prices of each of the products, we have;

The profit from the sale of the first product = 30% of x = 0.3·x

The loss from the sale of the second product = -30% of x = -0.3·x

The total gain or loss = Profit + Loss = 0.3·x + (- 0.3·x) = 0

Therefore, there is no net loss

The total loss incurred = 0%.

Answer:

x = 60.6

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp /adj

tan x = 3.9/ 2.2

Taking the inverse tan of each side

tan ^-1 (tan x )=  tan ^-1(3.9/ 2.2)

x=60.57254

To the nearest tenth

x = 60.6

Answer:

III (third) quadrant

Step-by-step explanation:

Answer: Choice B

Quadrant II, because the slope is positive and the y intercept is negative.

===============================================================

Explanation:

The y intercept is -6 which places the graph below the x axis when x = 0. The graph will go uphill as we move to the right (since the slope is positive), so we cut through quadrant 4 and move to quadrant 1 at some point. Going in reverse of this, we go through quadrant 3.

Only quadrant 2 is never passed through or touched at all.

------------

Here's another way to see why this is. Notice that x < 0 is the case for quadrant 2 since we're to the left of the vertical y axis. If x is negative, then so is (2/3)x. Recall that negative times positive = negative.

Adding on -6 to any negative value just gets us in even more negative territory. So ultimately, y is always negative when x < 0.

But if x < 0 leads to y < 0, then we're in Q3 and not Q2. In short, x < 0 will never get us to Q2 no matter what negative x value we pick.

The graph below hopefully visually summarizes and confirms what we discussed so far.

Answer:

You can buy 40 tacos

You have enough money

Step-by-step explanation:

Given

[tex]Amount = \$20[/tex]

[tex]Taco = 20[/tex]

[tex]Unit\ Cost = \$0.50[/tex] --- missing from the question

Required

Determine if you have enough amount

The number of Tacos that $20 can afford is calculated as:

[tex]Tacos = \frac{Amount}{Unit\ Cost}[/tex]

So, we have:

[tex]Tacos = \frac{20}{0.50}[/tex]

[tex]Tacos = 40[/tex]

[tex]40 > 37[/tex] -- i.e. the number of Tacos will go round the 37 students

Hence, you have enough money

Answer

(36)^1/2=(2^5)^1/2=6

Explanation

36 is equivalent to 2^5.

36^1/2 is equivalent to 6. The numerator of the fraction is the power and the denominator is the root. 36^1/2 is the same thing as the square root of 36, which is 6.

Answer:

[tex]19 = s + p[/tex] and [tex]121 = 7s + 10p[/tex]

Step-by-step explanation:

First we use constraints given by the problem to set up two equations:

We can only have a total of 19 bags, so:

[tex]19 = s + p[/tex]

Then, we want to maximize her sugar load. Using the info on the weight of each bag and the max carrying capacity:

[tex]121 = 7s + 10p[/tex]

Answer:

Step-by-step explanation:

Let the sugar from 7 pound bags be represented by = s

And let the sugar from 10 pound bags be represented by = p

As given, Captain Liz has room for 19 bags of sugar.

This becomes [tex]s+p=19[/tex]      .......(1)

Also given is , she has room for 19 bags of sugar, so equation becomes:

[tex]7s+10p=121[/tex]     ............(2)

Hence, these are the correct equations.

Answer:

True

Step-by-step explanation:

Two angles form a pair of complementary angles

1) 8

2) 6(5x+2y) factor out greatest common factor

3) 10.8 just move over decimal two places to the left.

4) 30t=150? Then t=5kg Im not sure what the last one is asking, but I’m assuming it’s to solve for t.

Answer:

a. <2 and <4

b. <5 and <8

c. <6 and <7

Step-by-step explanation:

a. Vertical angles are pairs of opposite angles formed by intersecting lines (they have congruent angles).

b. Linear pairs are the adjacent angles formed by the intersection of two lines. The sum of linear pairs is always 180 degrees.

c. A pair of angles whose sum is equal to 180 degrees.

hope it helps!

Answer:

a) <7 and <5

b) <2 and <3

c) <6 and <7

Step-by-step explanation:

a) Vertical angles that have the same point, and have the same angle degrees. Such as <7 and <5.

b) A Linear pair is two angles that add up to 180 and are next to each other. Such as <2 and <3.

c) Similar to linear pair, supplementary angles are two that add up to 180. Such as <6 and <7

Answer:

16 direct

17 indirect

Step-by-step explanation:

16.

If it is a direct variation

y/x = constant

4/-2  -2

-8/4 = -2

-12/6 = -2

This is a direct variation

17.

y/x = -1/2 /-2 = 1/4

y/x = -1/-1 = 1

This is not a direct variation

If it is an indirect variation then

yx = constant

-1/2 * -2 = 1

-1*-1 =1

3 * 1/3 =1

This is an indirect variation

Answer:

25

Step-by-step explanation:

The median of a trapezoid equals one half of the sum of the bases

AC is a median and EB and DF are the bases.

hence AC = 1/2(EB + DF)

We are given that EB = 13 and that AC = 19. And we need to find DF

To do so we plug in what we are given and solve for DF

AC = 1/2(EB + DF)

AC = 19, EB = 13

19 = 1/2(13 + DF)

Now solve for DF

* Multiply both sides by 2*

19 * 2 = 38

1/2(13 + DF) * 2 ( the 1/2 and 2 cancel out and we're left with 13 + DF )

We then have 38 = 13 + DF

* Subtract 13 from both sides *

38 - 13 = 13 - 13 + DF

We get that DF = 25

Answer:

A. A Rhombus is a regular polygon

Answer:

a) 10 blue balls, b) 5/18

Step-by-step explanation:

a)

R=3, G=5, B=x (unknown)

probability of picking red = 1/6 and red = 3 so total = 3(6) = total is 18

3+5 = 8 so B=18-8 -> B=10

b) total is 18 and G=5 so green probability = 5/18

Answer:

[tex]\boxed{ \sf Cuts \ x-axis \ at \ (9,0 ).}[/tex]

[tex]\boxed{ \sf Cuts \ y-axis \ at \ (0,6).}[/tex]

Step-by-step explanation:

We need to graph a linear equation and we need to find the point on which it crosses the x and y axis . The given equation is,

[tex]\sf\longrightarrow 2x + 3y = 18 [/tex]

For graphing it's line we need at least two points . hair we can find out the points on which it cuts the x and y axis and then using those two points we can plot its graph.

Step 1 : Put x = 0 in the equation :-

[tex]\sf\longrightarrow 2*0 + 3y = 18 [/tex]

Simplify ,

[tex]\sf\longrightarrow 0 + 3y = 18[/tex]

Add ,

[tex]\sf\longrightarrow 3y = 18[/tex]

Divide both sides by 3 ,

[tex]\sf\longrightarrow \underline{\purple{ y = 6}}[/tex]

Step 2: Put y = 0 in the equation :-

[tex]\sf\longrightarrow 2x + 3*0 = 18 [/tex]

Simplify ,

[tex]\sf\longrightarrow 2x = 18 [/tex]

Divide both sides by 2 ,

[tex]\sf\longrightarrow \underline {\purple{x = 9}}[/tex]

Hence the line cuts y axis on (0,6) and on x axis at (9,0) . Now these two points plot the graph . [ Graph is in attachment ]

Answer:

y = 4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 4x+b

Substitute the point in and solve for b

3 = 4(1)+b

3 = 4+b

3-4 = b

-1 =b

y = 4x-1

Answer:

y = 4x - 1

Step-by-step explanation:

y = mx + b

y = 4x + b

3 = 4(1) + b

3 = 4 + b

b = -1

y = 4x - 1
