Answer: 136

Step-by-step explanation:

17*8=136

Answer:

x=35

y=145

z=25

Step-by-step explanation:

(do first)x:

55 + 90 = 145

180-145=35

(do last)y:

25+10=35

180-35=145

(do second)z:

65+90=155

180-155=25

Answer:

x = 35, y = 145, z = 25

Step-by-step explanation:

All triangles' angles have a sum of 180°. Because we know this, we can solve the first triangle easily.

180 = x + 90 + 55

180 = x + 145

35 = x

Angles x and y are what we call suplementary angles. This means they have a sum of 180°.

180 = 35 + y

145 = y

Once again, we know that triangles have a sum of 180°. So the next triangle should now be easy to solve.

180 = 10 + 145 + z

180 = 155 + z

25 = z

Answer:

The roots are;

x = (2 + i)/5 or (2-i)/5

where the term i is the complex number representing the square root of -1

Step-by-step explanation:

Here, we want to use the completing the square method to solve the quadratic equation;

f(x) = -5x^2 + 4x -1

Set the function to zero

0 = -5x^2 + 4x - 1

So;

-5x^2 + 4x = 1

divide through by the coefficient of x which is -5

x^2 - 4/5x = -1/5

We now take half of the coefficient of x and square it

= -2/5^2 = 4/25

add it to both sides

x^2 - 4x/5 + 4/25= -1/5 + 4/25

(x- 2/5)^2 = -1/5 + 4/25

(x - 2/5)^2 = -1/25

Take the square root of both sides

x - 2/5 = √( -1/25

x - 2/5 = +i/5 or -i/5

x = 2/5 + i/5 or 2/5 - i/5

Answer:

B. They are alternate interior angles, so angle 3 also measures 130°.

Explanation: This is the correct answer on Edge 2021, just took the unit test. Hope this helps ^-^.

They are alternate interior angles, so angle 3 also measures 130°. The correct option is B.

The angle formed by the line intersecting two parallel lines is called the alternate interior angle. These two angles are equal in magnitude.

Here, according to the given figure, lines a and c are parallel lines and pipe cleaner is a transversal that is passing through these parallel lines.

Therefore, by the property of parallel lines, the corresponding and alternative exterior or interior angles made by the common transversal ( pipe cleaner) on lines a and c must be equal, and here ∠3 and 130° are alternative interior angles by lines a and c with the same transversal, So, they must be equal.

The complete question is given below:-

A pipe cleaner lay across a wire shelf. The wires that make up the shelf are parallel, and the pipe cleaner is a transversal. The parallel wires are labeled a, b, and, c, and the angles are labeled with numbers. The measure of one angle is 130°. Which statement is true regarding the 130° angle and angle 3?

A. They are same-side interior angles, so angle 3 measures 50°.

B. They are alternate interior angles, so angle 3 also measures 130°.

C. They are corresponding angles, so angle 3 also measures 130°.

D. They are alternate exterior angles, so angle 3 measures 50°.

Answer: 1.26 inches

explanation :

because if you subtract 7 by 3.2 you'll get

3.8, 3.8 will be the total of rain if you add week 1 2 4 , then youll have to find the average by dividing 3.8 by 3 youll get 1.26 . so that means the average lenth of the rain for 1 2 4 is 1.26 inches

Answer:

83.04

Step-by-step explanation:

First, you need to know how many drivers there are. But if the question doesn't tell you how many drivers then the answer would be 83.04 for one bus driver. If you forgot to add how many drivers then you can just multiply 83.04 to how many bus drivers then you get your answer.

Answer:

20

Step-by-step explanation:

1 hour = 60 minutes

1200 riders = 60 minutes: divide by sixty to set equal to 1

20 riders = 1 minute

Just divide 1,200 by 60 because there are 60 minutes in 1 hour.

Just think about it this way: If you eat 1 banana a minute, you eat 60 bananas an hour. The amusement park ride goes around once a minute. In one hour it goes around 60 times. Each time it carries the same amount of people.

1,200 divided by 60 is...

20!

The ride can carry 20 riders each ride, and each ride lasts a minute.

Given :

One cell phone company offers a plan that costs $26.99 and includes unlimited night and weekend minutes.

Another company offers a plan that costs $18.99 and charges $0.35 per minute during nights and weekends.

To Find :

For what numbers of night and weekend minutes does the second company's plan cost more than the first company's plan.

Solution :

Let, after n number of nights and weekends second plan is most costly.

So,

[tex]18.99+0.35x > 26.99\\\\0.35x > 8\\\\x>22.85[/tex]

Therefore, after 22 night and weekends second plan is  most costly.

Hence, this is the required solution.

Answer:

2 miles per hour

Step-by-step explanation:

We use the distance formula. D = r * t

45/3 = 15 mph | Trip 1 |

44/4= 11mph | Trip 2 |

15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.

Step-by-step explanation:

you have a defined value by not having a Y so you basically can not put x=-6 because x actually equals 2!

Answer:

3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (- 3, - 1)

d = [tex]\sqrt{(-3-0)^2+(-1+4)^2}[/tex]

   = [tex]\sqrt{(-3)^2+3^2}[/tex]

   = [tex]\sqrt{9+9}[/tex]

   = [tex]\sqrt{18}[/tex]

   = [tex]\sqrt{9(2)}[/tex]

    = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Hey there!

Given;

The points are;(0,-4) and (-3,-1).

Use formula for distance between the two points.

[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

Put all values.

[tex]d = \sqrt{( { - 3 - 0)}^{2} + ( { - 1 + 4)}^{2} } [/tex]

Simplify to get answer.

[tex]d = \sqrt{9 + 9} [/tex]

[tex]d = \sqrt{18} [/tex]

[tex]d = 3 \sqrt{2} [/tex]

Therefore, the distance is 3√(2) units or 4.24 units.

Answer:

C. Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero

Step-by-step explanation:

We want to see if all rational functions always have at least one asymptote or hole.

The answer is C:

" Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero"

A rational function is something like:

[tex]f(x) = \frac{q(x)}{p(x)}[/tex]

Where q(x) and p(x) are polynomials.

The asymptotes or holes happen when the denominator is equal to zero and the numerator don't.

Now, in the cases where the numerator and denominator become zero for the same value of x, it means that we can factorize the polynomials and remove the common factor. So there we do not have a hole nor asymptote.

Now, because the denominator becomes equal to zero, this means that we are dividing by a reallly small value, then the quotient will tend to infinity or negative infinity, this means that we will have a vertical asymptote.

Then the correct option is C:

Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
