Answer:

50° = 3x + 1, and x ≅ [tex]16.3^{o}[/tex]

Step-by-step explanation:

An angle bisector divides a given angle into two equal part in degrees.

Now, given that we have <ABC which has been bisected into two angles 50° and 3x + 1.

Since the two angles are equal, then;

50° = 3x + 1   (bisection property of an angle)

So that,

50° - 1 = 3x

49 = 3x

Divide both sides by 3, to have;

x = [tex]\frac{49}{3}[/tex]

  = [tex]16.3^{o}[/tex]

Therefore, the value of x is approximately [tex]16.3^{o}[/tex].

Answer:

B) The distance between communities B and c is 4.95 km.

Step-by-step explanation:

A) Join communities B and C. Then bisect angles A, B and C to determine the mid point equidistant to the three communities. The point where the three bisectors meet, w, is the exact place to dig the well.

The sketch is in the attachment to this answer.

B) Since we have two sides and an included angle, the cosine rule is applicable to determine a (distance between B and C).

[tex]a^{2}[/tex] = [tex]b^{2}[/tex] + [tex]c^{2}[/tex] - 2bc Cos A

b = 7 km, c = 5 km and A = [tex]45^{o}[/tex]. So that;

[tex]a^{2}[/tex] = [tex]7^{2}[/tex] + [tex]5^{2}[/tex] - 2(5 x 7) Cos [tex]45^{o}[/tex]

   = 49 + 25 - 70 x 0.7071

  = 74 - 49.497

  = 24.503

⇒ a = [tex]\sqrt{24.503}[/tex]

      = 4.95

The distance between communities B and c is 4.95 km.

Step-by-step explanation:

The table shows the height of water in a pool as it is being filled. A table showing Height of Water in a Pool with two columns and six rows. The first column, Time in minutes, has the entries, 2, 4, 6, 8, 10. The second column, Height in inches, has the entries, 8, 12, 16, 20, 24. The slope of the line through the points is 2. Which statement describes how the slope relates to the height of the water in the pool? The height of the water increases 2 inches per minute. The height of the water decreases 2 inches per minute. The height of the water was 2 inches before any water was added. The height of the water will be 2 inches when the pool is filled.

Answer:

The height of the water increases 2 inches per minute. The height of the water decreases 2 inches per minute. The height of the water was 2 inches before any water was added. The height of the water will be 2 inches when the pool is filled.

Answer:

(THE SPACES ARE THE FRACTIONS)

Step-by-step explanation:

Hence it is a simply rearrangement of the equation to start with, in order to make  

y

the subject:

2

x

+

3

y

=

1470

3

y

=

1470

−

2

x

y

=

3

−

2

3

y

=

−

2

3

x

This is the graph in ’slope-intercept’ form. From here it is easy to see that gradient  =  

−

2

3

and that y-intercept = 490.

The easiest way to draw a straight-line graph, such as this one, is to plot the y-intercept, in this case (0, 490), then plot another point either side of it at a fair distance (for example substitute  

x

= -5 and  

x

= 5 to procure two more sets of co-ordinates). These can be joined up with a straight line to form a section of the graph, which would otherwise extend infinitely either side - use the specified range in the question for x-values, and do not exceed it (clearly here the limit of  

x

-values is 0 ≤ x ≤ 735, since neither x nor y can be negative within the context of the question - the upper limit was found by substituting  

y

= 0).

In function notation, the graph is:

f

(

x

)

=

490

−

2

3

x

The graph of this function represents how the value of the function varies as the value of x varies. Looking back at the question context, this graph specifically represents how many wraps could have been sold at each number of sandwich sales, in order to maintain the same profit of $1470.

When the profit is higher, the gradient is not changed (this is defined by the relationship between the $2 and $3 prices, not the overall profit) - instead the  

y

-intercept is higher:

2

x

+

3

y

=

1593

y

2

y

−

3

x

y

=

531

−

2

3

x

Therefore we have gleaned that the new y-intercept is 531.

Clearly I cannot see the third straight line. However the method for finding the equation of a straight line graph is fairly simple:

1. Select two points on the line and write down their coordinates

2. The gradient of the line =  

c

h

a

n

g

e

−

i

y

−

3. Find the change in  

y

(Δ

y

=

y

2

−

y

4. Find the change in  

x

(Δ

x

=

x

2

−

x

1

5. Divide the result of stage 3 by the result of stage 4

6. This is your gradient

7. Take one of your sets of coordinates, and arrange them in the form  

y

=

m

x

+

c

, where your  

m

is the gradient you just calculated

8. There is only one variable left, which is  

c

(the y-intercept). Simply solve for this

9. Now generalise the equation, in the form  

y

=

m

x

+

c

, by inputting your gradient and y-intercept whilst leaving the coordinates as  

y

and  

x

For example if the two points were (1, 9) and (4, 6):

Δ

y

= 6 - 9 = -3

Δ

x

= 4 - 1 = 3

m

=  

−

3

3

= -1

I choose the point (4, 6)

6 = (-1 * 4) + c

6 = c - 4

c = 10

Therefore, generally,  

y

=

10

−

x

Within the context of the question, I imagine the prices of the two lunch specials will be the same in the third month and hence the gradient will still be  

−

2

3

- this means steps 1-6 can be omitted. Furthermore if the axes are clearly labelled, you may even be able to just read off the y-intercept and hence dispose with steps 1-8!

Answer:

7:30 a.m

Step-by-step explanation:

Number of miles from house to school(d) = 15 miles

Speed limit (s) = 30 mph

t1 = time to be in school is at most 8:00a.m

t0 = time to leave house

Given the model. :

15 = 30(8 - t2)

15 = 240 - 30t2

30t2 = 240 - 15

30t2 = 225

Divide through by 30

30t2 / 30 = 225/30

t2 = 7.5

Hence, I need to leave home by 7.5 (.5 in minutes = 0. 5*60 = 30 minutes)

Hence, t0 = 7:30,; I need to leave home by 7:30 a.m

Answer: 60

Answer:

The absolute value of any positive number is the number itself, so 11 has 11 as an absolute value. Also, the absolute value of a negative number is its (positive) opposite, so also has 11 as an absolute value.

El valor absoluto de cualquier número positivo es el número en sí, por lo que 11 tiene 11 como valor absoluto. Además, el valor absoluto de un número negativo es su opuesto (positivo), por lo que también tiene 11 como valor absoluto.

"Keith has $500 in a savings account at the beginning of summer he wants to atleast have $200 at the end of summer he withdraws $25 per week for food clothing and movie tickets how many weeks can keth with draw from his account"

given data

amount at hand=$500

amount expected= $200

weekly deduction from amount at hand=$25

Note: this is a reduction situation at a rate of $25

the expression for the situation is given as

y=c-mx

where y=200

c=500

m=25

substituting we have

200=500-25x

solving for x we have

200-500=-25x

-300=-25x

divide both sides by 25 we have

x=300/25

x=12 weeks

Answer:

[tex]35t^{9}[/tex]

Step-by-step explanation:

Since you're multiplying these terms together, you would multiply the base numbers and add the exponents.

Base: 5 × 7 = 35

Hope this helps! I apologize if I'm incorrect

The multiplication of this expression (5t⁶)(7t³) is 35t⁹

To determine the multiply of

(5t⁶)(7t³)

First multiply the base numbers.

Base: 5 × 7 = 35

Then, add the exponents together
