Help!!! What is the slop of the line??

Answer:

9 hours

Step-by-step explanation:

We can use a ratio to solve

247 dollars       171 dollars

---------------- = -------------

13 hours             x hours

Using cross products

247* x = 13*171

247x =2223

Divide each side by 247

247x/247 =2223/247

x=9

Answer:

Step-by-step explanation:

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,

x = (2 · 8 + 5 · -6) / (2 + 5)

x = (16 - 30) / (7)

x = - 14 / 7

x = - 2

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Answer:

Number of step Marcela walk = 1,350 steps

Step-by-step explanation:

Given:

Distance between Marcela house and grandmother house = 540 meter

Each step of Marcela = 4/10 meter

Find:

Number of step Marcela walk

Computation:

Number of step Marcela walk = Distance between Marcela house and grandmother house / Each step of Marcela

Number of step Marcela walk = 540 / (4/10)

Number of step Marcela walk = 540 / 0.4

Number of step Marcela walk = 1,350 steps

Answer:

radius = 10 units

Step-by-step explanation:

using the Pythagorean theorem:

height of triangle = 6 units

base of triangle = 16/2 = 8 units

radius² = 6² + 8² = 36 + 64 = 100

radius = √100 = 10 units

Answer:

x = 3/2

Step-by-step explanation:

x- 3/4 + 2/3 = 17/12

x = 17/12 + 3/4 -2/3

x = 3/2

Answer:

yn +y -xn

Step-by-step explanation:

Mean= sum of numbers ÷number of numbers

x= sum of n numbers ÷n

Multiply both sides by n:

xn= sum of n numbers

sum of n numbers= xn -----(1)

Let the number added be a.

After a has been added,

y= (sum of n numbers +a) ÷(n+1)

Multiply both sides by (n +1):

y(n +1)= sum of n numbers +a

sum of n numbers= y(n +1) -a -----(2)

Substitute (1) into (2):

xn= y(n +1) -a

Expand:

xn= yn +y -a

a= yn +y -xn

Let's check!

Let the numbers be 1, 2, 3 and 4.

mean, x= 10 ÷4= 2.5

n= 4

Let the new number added, a, be 7.

a= 7

mean, y= 17 ÷5= 3.4

a= yn +y -xn

a= 3.4(4) +3.4 -2.5(4)

a= 7

Thus, the expression is true.

Answer:

x=2  y=-4

Step-by-step explanation:

2x-y=4   solve for x

2x-0=4

2x=4+0

2x=4 . divide both sides by 2

x=2

2x-y=4 .  solve for y

0-y=4

-y=4 . divide both sides by -1

y=-4

Answer:

Step-by-step explanation:

the appropriate null and alternative hypotheses's are something

Answer:

It is given that y represents the profit earned, and x represents the number of lunch specials ordered at Juan's restaurant per hour.

To determine the maximum profit Juan's restaurant will earn from lunch specials, estimate the highest y-value from the graph. From the graph, it can be seen that the maximum y-value is halfway between 110 and 120. So, the maximum profit Juan's restaurant will earn from lunch specials per hour is about $115.

Next, to determine when the restaurant will break even, observe the x-value when y = 0. It can be seen that graph crosses the x-axis in two places, when x = -5 and x = 10. Since x represents the number of lunch specials ordered, the x-value must be positive. So, the restaurant will break even after 10 lunch specials are ordered.

Lastly, to determine the interval on which the restaurant makes a profit, observe from the graph where the values of x and y are positive. So, the interval on which the restaurant makes a profit is (0, 10).

Step-by-step explanation:

115, 10, (0,10)

^those are the answers

The maximum profit earned from lunch special orders per hour is about [tex]\$ 112.5[/tex]. The restaurant will break even if [tex]10[/tex] lunch specials are ordered.

Profit is the amount which we earned after selling something more that its cost price.

We have,

Profit earned [tex]=y[/tex],

The number of lunch specials ordered per hour [tex]=x[/tex]

Now,

From the graph,

Profit(y)  [tex]=a(x+5)(x-10)[/tex]

[tex]y=a[x^2-10x+5x-50][/tex]

[tex]y=a[x^2-5x-50][/tex]

Now,

When [tex]x=0[/tex]  ,

then,

[tex]y=-50a[/tex]     [tex].....(i)[/tex]

And,

From graph When [tex]x=0[/tex] ,

[tex]y=100[/tex]     [tex].....(ii)[/tex]

So, from above equations ,

[tex]-50a=100[/tex]

[tex]a=-2[/tex],

Now,

[tex]y=a[x^2-5x-50][/tex]

Substituting value of a,

[tex]y=[-2x^2+10x+100][/tex]

[tex]y=[-2(x^2-5x)+100][/tex]

[tex]y=[-2(x^2-5x-(\frac{5}{2})^2 )+100+2(\frac{5}{2})^2][/tex]

[tex]y=[-2(x-\frac{5}{2} )^2+112\frac{1}{2}[/tex]

So,

Now

The maximum profit will be ,

From graph,

When [tex]x=\frac{5}{2} = 2.5[/tex]

So,

Putting value of x,

We get,

[tex]y=112.5[/tex]

So, the maximum profit earned from lunch special orders per hour is about [tex]\$ 112.5[/tex].

Now,

When [tex]y=0[/tex] then [tex]x=-5[/tex] or [tex]x=10[/tex]

As [tex]x > 0[/tex]

So,

The restaurant will break even if [tex]10[/tex] lunch specials are ordered.

Hence we can say that the maximum profit earned from lunch special orders per hour is about [tex]\$ 112.5[/tex]. The restaurant will break even if [tex]10[/tex] lunch specials are ordered.

Answer:

320 cm² or 264 cm²

Step-by-step explanation:

first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²

the 2 square faces will be either 8 x 8 or 6 x 6.

If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²

If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²

Answer:

In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.

Step-by-step explanation:

The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.
