Answer:

see explanation

Step-by-step explanation:

2 chords intersecting inside a circle , then the product of the parts of one chord is equal to the product of the parts of the other chord.

6

BE × ED = AE × CE , that is

10 × 3x = 12(2x + 1) ← distribute parenthesis by 12

30x = 24x + 12 ( subtract 24x from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

then

ED = 3X = 3(2) = 6

7

RJ × JP = SJ × JQ , that is

6 × 3x = 4(4x + 1) ← distribute parenthesis by 4

18x = 16x + 4 ( subtract 16x from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

then

RP = RJ + JP = 6 + 3x = 6 + 3(2) = 6 + 6 = 12

Cesar had a part-time job last year. He worked every week for the year and made $23 an hour. He worked 28 hours each week. Cesar
Naddika [18.5K]

Answer:

D. $2,511

Step-by-step explanation:

First off, we need to write down the facts we know.

There are about 52.177 weeks in a year

Cesar works 28 hours each week

Cesar makes $23 an hour

There are 12 months in a year

Cesar has $3,360 after his monthly expenses

To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses.

What are the factors of the function represented by this graph? the graph of a quadratic function y = (1/4)(x + 4)(x - 8) with a
Inga [223]

Answer:

<u>option C. (x + 4) and (x − 8)</u>

Step-by-step explanation:

A factor is one of the linear expressions of a single-variable of the polynomial.

Given: y = (1/4)(x + 4)(x - 8)

When y = 0

∴ (1/4)(x + 4)(x - 8) = 0 ⇒ multiply both sides by 4

∴ (x + 4)(x - 8) = 0

So, the factors of the function are (x+4) and (x-8)

The answer is option <u>C. (x + 4) and (x − 8)</u>

In the figure below, which term best describes point X?
sergiy2304 [10]

The term best describes point X is option A. Centroid.

<h3>What is the centroid of a triangle and its coordinates?</h3>

The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).

If the surface is plane triangle approximately and mass is uniformly distributed, then its center of mass will lie on the centroid of that triangle.

If the triangle has its vertices as   (x_1, y_1), (x_2, y_2) , \: (x_3, y_3)then the coordinates of the centroid of that triangle is given by:

(x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)

The term best describes point X is option A. Centroid.
