What kind of line is being constructed in the series of diagrams?

Mathematics

Answer:

Perpendicular

Step-by-step explanation:

In figure (i), with Q as centre and any radius  we make two arcs on the line  (using compass) such that each of the arc is equidistant from Q.

Mark the intersecting points on the line as A and B. (see figure (i) )

Now, take A as centre and open compass more than half of the line i.e,  more than AQ, draw an arc (see figure (ii) ).

With the same radius as in figure (ii) and centre B , draw an arc which intersects the previous arc at point P. (see figure (iii) )

If we draw line from the intersecting point P to the line, we get a perpendicular .

So, second option is correct .

Answer:

∠ 1 = 99°, ∠ 2 = 81°, ∠ 4 = 81°

Step-by-step explanation:

∠ 1 and ∠ 3 are vertical angles and are congruent, then

∠ 1 = 99°

∠ 1 and ∠ 2 are adjacent angles and sum to 180° , so

∠ 2 = 180° - 99° = 81°

∠ 2 and ∠ 4 are vertical angles and are congruent, so

∠ 4 = 81°

A manager is comparing the cost of buying ball caps with the team emblem from two different companies. Company X charges a $50 f
Nady [450]

Answer:

10 ball caps

Step-by-step explanation:

In this question, we are trying to know the number of caps the manger would buy that would equate the cost at both companies.

How do we get this?

Since we do not know the number of caps, let’s assign a variable. Let the number of caps that is required be x. Let’s now make some costings in terms of x. We proceed;

Company X charges $50 fee plus $7 per cap. Total amount company X will charge on x caps will be; $50 + $7(x) = $50 + $7x

Company Y will charge $30 plus $9 per cap. Total amount company Y will charge on x caps will be $30 + $9(x) = $30 + $9x

We are trying to look at the value of x that will make both costs equal. What we do is to equate both costs.

30 + 9x = 50 + 7x

We simply by taking like terms to the same sides

9x-7x = 50-30

2x = 20

x = 20/2 = 10

X = 10

So what this means is that manger has to buy 10 caps to have the same cost in both companies

What is the goal in solving an equation?
Lelechka [254]

Your answer is, get the variable by itself.

The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

<h3><u>What is an equation?</u></h3>

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =

<h3><u>3 types of equations</u></h3>
  • slope-intercept form
  • point-slope form
  • standard form

Thus, <u>option a</u> is your answer.
