Answer:

Step-by-step explanation:

To find the minimum amount of items, x, that need to be sold for the manufacturer to make a profit, we can use the quadratic formula

[tex]x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}; x= \frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

[tex]x= \frac{-700+\sqrt{700^{2}-4(a)(-10000) } }{2(1)}; x= \frac{-700-\sqrt{700^{2}-4(a)(-10000) } }{2(1)}[/tex]

[tex]x= \frac{-700+\sqrt{530000} }{2}; x= \frac{-700-\sqrt{530000} }{2}[/tex]

[tex]x=\frac{-700+100\sqrt{53} }{2}; x=\frac{-700-100\sqrt{53} }{2};[/tex]

[tex]x=-350 + 50\sqrt53 = 14.005; x = -350 - 50\sqrt53 = -714.005[/tex]

In context of the problem, we can only rely on the positive value, as the negative value would lead to a loss of profit.

[tex](-714.005)^2+700(-714.005)-10000=-0.360[/tex]

Furthermore, we must round to the nearest whole number, as you cannot make part of an item.

Lastly, if you were to plug in 14 into the equation for Profit, you would still have a negative number (i.e. a negative profit), thus requiring the manufacturer to make no less than 15 items to make a profit:

[tex](14)^2+700(14)-10000=-4\\\\(15)^2+700(15)-10000=725[/tex]

Answer:

ok i am here to explain :)

Step-by-step explanation:

So, for #6, all we do is -8+6, since it said sum, so we add, and we get -2. this is 2 more than -4, and to check, all we would have to do is -4+2, which equals -2.

for #7, all we have to do is -8+(-6), since again it says sum so we add. the sum of these values are -14. for the second part, because it says "product" this means we multiply! and when we multiply -2 by 4, we get -8. this would lead us to believe that the sum is 4 less than. we can check it by subtracting positive 4 from the  negative 8, or -8-4, which would give us -12.

for #11, all i really did was plug it into a calculator, and for the first one, i got 4, and for the second one i got -4. this would give us a difference of 8, and to check all we would have to do is add the 8 to the negative 4, or -4+8=4.

Hope this helps, please mark as brainlest.

Answer:

6: -2

7: 14

11: -4

Step-by-step explanation:

6:

-8 + 6 = -2

-2 is bigger than -4 because it is closer to 0. If it was regular numbers, like 2 and 4, 4 would be larger! :)

7:

-8 - 4 = -12

4 - 2 = 2

The correct answer is 14 because there are 14 numbers between 4 and -12 :)

11:

Answer:

x = 16 or -2

Step-by-step explanation:

If both lines are congruent, their magnitudes are equal.

To find the magnitude of a line, the equation to use is;

D = √(x2-x1)^2 + (y2-y1)^2

So for AB, we have

D = √(-2 + 11)^2 + (5 + 3)^2

D = √81 + 64 = √145

For the second line

The distance would be;

D = √x-7)^2 + (9-1)^2

D = √(x-7)^2 + 8^2

Equate both magnitude

√145 = √(x-7)^2 + 64)

Simply remove the square roots on both sides

145 = 64 + (x - 7)^2

145 -64 = (x -7)^2

81 = (x-7)^2

Thaw the square root of both sides

x - 7 = 9

or x -7 = -9

x = 9 + 7 or x = -9 + 7

x = 16 or -2

Step-by-step explanation:

phythagorean theorm

The measure of x from the triangle is x = 4

A planar figure or polygon having three sides and three angles is called a triangle.

The internal angles of a triangle, which has three vertices, add up to 180 degrees.

Assume the triangle is ABC, with A + B + C equaling 180 degrees.

Triangle area equals (1/2) × Length x Base.

About a right triangle

According to the Pythagoras Theorem, If a2 + b2 = c2, then the hypotenuse2 = base 2 + height 2, making it a right triangle.

If a2 + b2 c2, the triangle is an acute triangle.

If a2 + b2 > c2, the triangle is sharp.

Given the data,

Let's use ABC to depict the triangle.

Now, the triangle's sides are measured in units of AB and y.

x units = BC

Moreover, AC = 8 units.

The trigonometric relationships show that sin = opposite / hypotenuse.

Hence, the definition of sin 30° is x / 8

With simplification, we have (1/2) = x / 8

8 is multiplied twice, giving us x = 8/2 x = 4 units.

Hence , the sides of the triangle are solved

Answer:

∠ CPM  = 135°

Step-by-step explanation:

given AC = BC , then Δ ABC is isosceles with base angles congruent , then

∠ ABC = [tex]\frac{180-40}{2}[/tex] = [tex]\frac{140}{2}[/tex] = 70°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then

∠ AMN + ∠ BPM = ∠ ABC , that is

25° + ∠ BPM = 70° ( subtract 25° from both sides )

∠ BPM = 45°

∠ CPM and ∠ BPM are adjacent angles on a straight line and sum to 180°

∠ CPM + 45° = 180° ( subtract 45° from both sides )

∠ CPM = 135°

Answer:

The formula should be the change in y-values with respect to the change in the x-values. She used an incorrect formula

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). Her work is shown below. Let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3). m = = = The slope is . What error did she make? She simplified the denominator incorrectly. The denominator simplifies to –7. She labeled the points incorrectly. The point (–7, 4) should be (x1, y1). She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values. She used an incorrect formula. The formula should be the sum of the x-values with respect to the sum of the y-values.

Slope of a line is expressed according to the formula;

Slope m = Δy/Δx

Slope = y2-y1/x2-x1

Given the coordinates (–7, 4) and (2, –3), from the coordinates;

x1 = -7, y1 = 4, x2 = 3, y2 = -3

Substitute into the formula;

Slope = -3-4/3-(-7)

Slope = -7/3+7

Slope = -7/10

Based on Anya workings, it can be concluded that Anya used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values

By what the question asks, I assume that this refers to getting the slope in a linear equation.

The correct option is:

She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values.

A general linear equation is given by:

y = a*x + b

where a is the slope and b is the y-intercept.

We know that for a line that passes through points (x₁, y₁) and (x₂, y₂) then the slope can be computed as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Notice that the formula is the change in y-values with respect to the x-values,

So we can conclude that the correct option is:

"She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values."

Why?

Because we have two right triangles with the same shared leg (the L of HL) and the hypotenuses are the same length (the H of HL). The tickmarks tell us those segments are the same.

HL only applies to right triangles because the hypotenuse is only found in right triangles. If we didn't have those 90 degree square markers, then this would be an SSA case, but that's not a valid congruence theorem.

m∠A = 150°

m∠B = 30°

m∠E = 110°

Step-by-step explanation:

Linear pair:

⇒ m∠A + 30° = 180°

⇒ m∠A = 150°

Alternate interior angles:

⇒ m∠B = 30°

Sum of interior angles of a triangle is 180°:

⇒ m∠C + 30° + 40° = 180°

⇒ m∠C = 110°

Linear pair:

⇒ m∠C + m∠D = 180°

⇒ 110° + m∠D = 180°

⇒ m∠D = 70°

Alternate interior angles:

⇒ m∠E = m∠C

Answer:

36 passengers

Step-by-step explanation:

Maria averages 20 passengers every 20 minutes, so she places 1 passenger per minute.

Sal averages 20 passengers every 25 minutes, so he places 0.8 passenger per minute.

If they work together, they can place (1 + 0.8) passengers = 1.8 passengers per minute.

In 20 minutes, they can load

1.8 passengers/minute * 20 minutes = 36 passengers

It took both Maria and Sal 11.1 minutes to load 20 passengers

The number of passenger Maria loads each minute = 20 passengers/20 minutes = 1 passenger per minute

The number of passenger Sal loads each minute = 20 passengers/25 minutes = 0.8 passenger per minute

Let t represent the total time taken to load the 20 passengers, hence:

(1 passenger per minute × t minutes) + (1 passenger per minute × t minutes) = 20 passengers

t + 0.8t = 20

1.8t = 20

t =  11.11 minutes
