Help! I’m stuck choose the right one..

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

Work Shown:

Refer to the diagram below. I've added a line segment and two variables y and z. This forms two isosceles triangles.

The central angle 56 degrees subtends the same arc as the inscribed angle y. By the inscribed angle theorem, this means y = 56/2 = 28. The inscribed angle is always half of the central angle (when both angles subtend the same arc).

Focus on the smaller isosceles triangle that has angles 56, z and z. Those three angles add to 180

z+z+56 = 180

2z+56 = 180

2z = 180-56

2z = 124

z = 124/2

z = 62

Now focus on the larger isosceles triangle (angles y = 28, x+z and x+z)

We'll use the same trick as before.

(x+z)+(x+z)+(y) = 180

(x+62)+(x+62)+(28) = 180 ... plug in z = 62 and y = 28

2x+152 = 180

2x = 180-152

2x = 28

x = 28/2

x = 14

Answer:

The range interval is: (7, -1)

Step-by-step explanation:

Given the function

g(x) = -2r+5

Let us put the domain values in the interval (-1, 3)

Putting x = -1

g(x)=-2r+5

      = -2(-1)+5

      = 2+5

      = 7

Putting x = 0

g(x)=-2r+5

      = -2(0)+5

      =0+5

      = 5

Putting x = 1

g(x)=-2r+5

      = -2(1)+5

      =-2+5

      = 3

Putting x = 2

g(x)=-2r+5

      = -2(2)+5

      =-4+5

      = 1

Putting x = 3

g(x)=-2r+5

      = -2(3)+5

      =-6+5

      = -1

Thus the range interval is: (7, -1)

Answer:

the answer of this qst is A

Applying the least common multiple, the fraction is rewritten as

[tex]\frac{4200(x+100)}{x(x+100)} + \frac{4200x}{x(x+100)}[/tex]

Which is option A.

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

The fraction given is:

[tex]\frac{4200}{x} + \frac{4200}{x + 100}[/tex]

When two fractions with different denominators are added, the first step is finding the least common multiple of the denominators. The lcm of x and x + 100 is x(x + 100), thus we use it to factor the fraction.

[tex]\frac{4200}{x} + \frac{4200}{x + 100} = \frac{4200\frac{x(x+100)}{x}}{x(x+100)} + \frac{4200\frac{x(x+100)}{x+100}}{x(x+100)} = \frac{4200(x+100)}{x(x+100)} + \frac{4200x}{x(x+100)}[/tex]

Which is option A.

Step-by-step explanation:

Answer:

16 square feet was left over after he cut out the windows

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where

∵ The dimensions of each window are 8-foot by 4-foot

∴ l = 8 feet and w = 4 feet

→ By using the rule above find the area of each window

∵ A = 8 × 4

∴ A = 32 feet²

∴ The area of each window = 32 feet²

∵ He cut 2 windows

∴ The area of the 2 windows = 2 × 32

∴ The area of the 2 windows = 64 feet²

∵ The area of the wall is 80 feet²

→ To find the area of the wall left, subtract the area of the windows from

   the area of the wall

∵ The area left = 80 - 64

∴ The area left = 16 feet²

∴ 16 square feet was left over after he cut out the windows

Answer:

4) x = - 12

5) x = 4

Step-by-step explanation:

4)

Since points T and S are mid points of sides ML and MN of triangle MLN.

Therefore, by mid point theorem,

TS is half of LN

so,

[tex]x + 26 = \frac{1}{2} (x + 40) \\ \\ 2(x + 26) =x + 40 \\ \\ 2x + 52 = x + 40 \\ \\ 2x - x = 40 - 52 \\ \\ x = - 12[/tex]

5) In the same way x = 4 will be the correct answer in question number 5.

Answer:10 adult and 20 children

Step-by-step explanation:

The two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Given that, a hairstylist charges $15 for an adult haircut at nine dollars for a child haircut she wants to earn at least $360.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the number of adults be x and the number of child be y.

So, x+y>30

Now, 15x+9y≤360

⇒ 3(5x+3y)≤360

⇒ (5x+3y)≤120

From the graph we can see that, two graphs intersecting at (15, 15)

Therefore, the two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Answer:

A)63miles per hour.

B)27 miles per hour

Step-by-step explanation:

HERE IS THE COMPLETE QUESTION

boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)??b) How fast does the current in the river flow?

Let the speed of boat in still water = V(boat)

speed of current=V(current)

To calculate speed of boat downstream, we add speed of boat in still water and speed of current. This can be expressed as

[V(boat) +V(current)]

It was stated that it takes 1hour for the

boat to travels between two points of 90 mi apart downstream.

To calculate speed of boat against current, we will substact speed of current from speed of boat in still water. This can be expressed as

[V(boat) - V(current)]

and it was stated that it takes 2 1/2 for return trip against the Current

But we know but Speed= distance/time

Then if we input the stated values we have

V(boat) + V(current)]= 90/1 ---------eqn(1)

V(boat) - V(current) = 90/2.5----------eqn(2)

Adding the equations we have

V(boat) + V(current) + [V(boat) - V(current)]= 90/2.5 + 90/1

V(boat) + V(current) + V(boat) - V(current)]=90+36

2V(boat)= 126

V(boat)=63miles per hour.

Hence, Therefore, the speed of boat in still water is 63 miles per hour.

?b) How fast does the current in the river flow?

the speed of the current in the river, we can be calculated if we input V(boat)=63miles per hour. Into eqn(1)

V(boat) + V(current)]= 90/1

63+V(current)=90

V(current)= 27 miles per hour

Hence,Therefore, the speed of current is 27 miles per hour.

Answer:

80 mm

Step-by-step explanation:

Pythagorean theorm can be applied here to solve for the length of the last leg, [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:

b = √c^2 - √a^2

  = √(82)^2 - √(18)^2

  = √6724 - √324

  = √6400

  = 80 mm

Answer:

r = -25

Step-by-step explanation:

slope is change in "y" over change in "x"

so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.

Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.

Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25

So the two points are (-5, 5) and (5, -25)

Answer:

As

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Step-by-step explanation:

We know that the special theorem of remainder states that:

if

[tex]x-k[/tex] is a factor of [tex]p(x)[/tex]

then

[tex]p(k) = 0[/tex]

so

[tex]x+5 = x-(-5)[/tex]

[tex]k = -5[/tex]

Thus,

[tex]p(k) = 0[/tex]

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Answer:

I think its 28.

Step-by-step explanation: Dont take my word for this tho

the ratio is 1:2 and that would mean that whatever length DA, HE is 2 times.

The length of BC is 14 so 14 x 2 is 28.

The length, in meters, of side FG on the photocopied image is 28 m and this can be determined by using the concept of dilation.

Given :

The following steps can be used in order to determine the length, in meters, of side FG on the photocopied image:

Step 1 - According to the given data, the side length of DA is 2 times the side length of HE.

Step 2 - From the above step, it can be concluded that 2 is the dilation factor.

Step 3 - From the given data, the length of BC is 14m. So, the length of the side FG is given by:

FG = 2 BC

Step 4 - Substitute the value of length of side BC in the above expression.

FG = 2(14)

FG = 28 m

Therefore, the correct option is C).

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the unit rate is termed as the slope of the line.

We also know that the slope is normally represented by a fraction which may be expressed as a unit rate found at the point on the graph.

We are given that a bottling machine fills 15 bottles of water every 6 seconds.

Thus,

unit rate = 15 bottles / 6 seconds

              = 2.5 bottles / 1 second

              = 2.5 bottles per second

Thus,

The unit rate = 2.5 bottles per second

We know that the unit rate represents the slope of the line which is normally represented by a fraction or ratio.

Therefore,

Slope = 15 / 6

          = 2.5
