i need help to solve please

Answer: the answer is below!!!!!!

Step-by-step explanation:

first: take 28 and divide it by 2 and you will get 14

now take 2 and divide it by 2 and you will get 1

now take the 14 put it over 1 like this------>14/1

Second:take the 5 and divide it by 2 and you get 2.5

not take the 2 and divide it by 2 and you get 1

now take 2.5 and put it over the 1 like this-------->2.5/1

third: take the 3 and divide it by 3/4  

Answer:

$16

Step-by-step explanation:

If 3 rides cost $28 and 6 rides cost 40, each ride costs $4. 28 - (3 x 4) = $16 admission fee

Answer:

9 - 7x - x²

Step-by-step explanation:

-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²

I arranged the like terms together so it is easier to do the calculations.

-4x-3x+2x2+5-x² = -7x+4+5-x²

Simplify.

-7x+4+5-x² = 9-7x-x²

Answer:

[tex]x^{2} -7x+5[/tex]

Answer:

your answer is not perpendicular

Step-by-step explanation:

so first you put the y which is -2 and the -x with -3

[tex]-2=(-3)-4[/tex]

when you subtract the -3 from 4 you will get 7

[tex]4-(-3)=7[/tex]

7 is not equal to -2 so it is not perpendicular

[tex]7\neq -2[/tex]

Answer:

Step-by-step explanation:

Given functions

Finding (r-s)(x), (r+s)(x), (r*s)(-1)

Answer:

1. - 2x² + x + 4

2. 2x² + x + 4

3. Answer = 3

Example functions we are given:

r(x) = x + 4

s(x) = 2x²

Now, we Find (r-s)(x), (r+s)(x), (r*s)(-1)

(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4

(r + s)(x) = r(x) + s(x) = x + 4 + 2x² =  2x² + x + 4

(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3

Answer:

75°

Step-by-step explanation:

we can form a triangle to help us understand how to solve this problem:

                                                    puppy

∠ Leslie = 35°                                                   ∠ Surekha = 70°

If Leslie's angle is 35° and Surekha's angle is 70°, that gives us a total of 105°. Since the sum of the triangle's three angles is 180°, then the angle at which they will meet is 180° - 105° = 75°

In this exercise, we have to calculate the angle of the path that they met, so we will have:

75°

We know that the geometric figure in question is a triangle and that the sum of its internal angles must be equal to 180 degrees, thus:

[tex]180-105=X\\180-105=75\\[/tex]

Step-by-step explanation:

Answer:

B. 2,324 inches

Step-by-step explanation:

You need to find the circumference of the bike wheels first so that you know how much she would travel if her wheels rotated 1 time. Circumference of circle = pi × d

1 time = 20pi

37 times = 20pi × 37

              = 740pi

              = 2324.778564...inches

The diameter of a cartwheel is 2.1 m. Find the distance travelled when it completes 100 revolutions.

You need to find the circumference of the cartwheels first so that you know how much it would travel if her wheels revoluted 1 time. Circumference of circle = pi × d

1 revolution = 2.1pi

100 revolutions = 2.1pi × 100

                          = 210pi

                          = 659.7344573...m

The diameter of a circular park is 98 m. Find the cost of fencing it at $4 per meter.

You need to find the circumference of the park first so that you know how much it would cost. Circumference of circle = pi × d

Circumference of park = 98pi

Cost of fencing = 4 × 98pi

                          = 392pi

                          = $1231.50

                          ≈ $1232.00

Answer: The diagonals are thus equal, and divides the rectangle into right triangles, whereas the diagonals of a parallelogram are not equal and bisect it into two congruent triangles with angles depending on that of the parallelogram.

Answer:

1/15 yards

Step-by-step explanation:

Total yards of packing tape = 4 yards

Yards used for his father = 1 3/5 yards

Yards used for another package = 2 1/3 yards

Total yards used = 1 3/5 + 2 1/3

= 8/5 + 7/3

= 24+35/15

= 59/15 yards

How many yards of packing tape does Carlos have left

Total yards left = Total yards of packing tape - Total yards used

= 4 - 59/15

= 60-59/15

= 1/15

Total yards left = 1/15 yards

Answer: equilateral

Step-by-step explanation:

Answer:

Always true

Step-by-step explanation:

The definition of an interior or internal angle bisector is the the dividing line segment that splits the angle into two  equal angles (parts)

Therefore, given that the segment BD is the bisector of ∠ABC, then the formed angles m∡ABD and m∡DBC are, by definition of bisected ∠ABC, always congruent

Answer:

The sides are 14.6, 14.6, 9.6

Step-by-step explanation:

Step one:

given

Perimeter= 49

let the equal sides of the triangle be x

so the third side will be x-5

hence the first side is=x

the second side =x

and the third side=x-5

the perimeter of triangle is

P= A+B+C

where A B and C represents all the sides

49=x+x+(x-5)

solve for x

49=2x+x-5

49=3x-5

49-5=3x

44=3x

x=44/3

x=14.6

Hence the third side is

=x-5=14.6-5

=9.6

The sides are 14.6, 14.6, 9.6
