Can someone explain number three to me? i don’t need the answers i just don’t understand

y + 11 = (1/4)(x + 16)

step-by-step explanation:

Perimeter is for a geometric shape (square, triangle, diamond, rectangle,etc.), whereas circumference is the “perimeter” of a circle

Perimeter is the limit of any given geometric figure. Circumference is just the name given to a circle’s perimeter, in other words, the circle’s limit, its edge.

The reason for this is because the perimeter is, by definition, the sum of the lenghth of every side of any given geometric figure. A circle has either no sides, or number of sides, so its perimeter has to be treated differently.

Remember that π (Pi) equals 3.141592 approximately. This is a constant, meaning that no matter what circle you are studying, Pi will always have the same value. It is the relation between the diameter and the lenght of its circumference. A circle with diameter xwill travel 3.141592x before it completes a revolution. This is where Pi comes from.

So the difference would be that a “normal” perimeter is only the sum of the sides. A circumference is the perimeter of a circle, given a diameter and the constant value of Pi, that derives from other properties of the circle, and not by its sides (remember a circle has either none or nnumber of sides).

Step-by-step explanation:

3.6repeating=3 2/3

2.3repeating=2 1/3

470 = 8.75(46 - c) + 11c

470 = 402.5 - 8.75c + 11c

67.5 = 2.25c

30 = c

If c = 30 and Soren worked 30 hours in the office, earning $11 per hour, he earns $330 from his office job. 46 - 30 = 16, which should be the remaining amount of hours Soren worked. 16 * 8.75 = 140. He earned $140 from his cashier job. $330 + $140 = $470.

The correct formula to solve this problem is A. 11c + 8.75(46 - c) = 470

Step-by-step explanation:

You'll have an idea of the positive or negative charge on the ion from the periodic table

For example Magnesium is in group 2 and its ionic charge is +2 Mg2+

In the higher groups the charge on the on is negative For example

Chlorine ion is Cl- (its in group 7 and it has (8-7) = 1 negative charge

Step-by-step explanation:

3 2/3 is the same as 11/3

2.33333... is the same as 2 1/3 and 7/3

11/3 + 7/3 = 18/3 = 6

Multiply the whole times the denominator and add that number to the top

Numerators can add. Denominators cannot.

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer

hope this helps

[tex]Hey can someone explain this to me i keep coming out with wierd answers? 2(50+2w)+2(w)=700[/tex]

Step-by-step explanation:

The radius is the distance from the center to the outer ring. The center is the middle dot you see. Circles are referred to by their center. Circle A is a circle with a point at the coordinate A.

The intersection of two circles is the area where they cross. Since they only touch at one point(tangent to each other), the intersection of these two circles will be a coordinate. The point of tangency will be the same point.

Option D:

Measure of arc BEC = 228°

Solution:

Given angle A = 114° and vertical angle of A = 0.

If two chords intersect inside the circle, then the measure of each angle is one half of the sum of the measures of the arcs intercepted by the angle and its vertical angle.

[tex]$\Rightarrow \angle A = \frac{1}{2} (ar \ BEC + vertical \ ar A)[/tex]

[tex]$\Rightarrow 114^\circ = \frac{1}{2} (ar \ BEC + 0)[/tex]

[tex]$\Rightarrow 114^\circ = \frac{1}{2} (ar \ BEC)[/tex]

Multiply by 2 on both sides, we get

[tex]$\Rightarrow 2\times 114^\circ = 2\times \frac{1}{2} (ar \ BEC)[/tex]

[tex]$\Rightarrow 228^\circ = (ar \ BEC)[/tex]

Measure of arc BEC = 228°

Option D is the correct answer.

2(50+2w)+2(w)=700

100+4w+2w=700

6w=700-100

6w=600

w=100

I think so
