Carpenters Charlie and Chris total charges would be equal after working for 10 hours

<h3>How to determine the number of hours?</h3>

Let x represent the number of hours, and y represent the amount earned.

So, the equations are:

Charlie, y = 15x + 100

Chris, y = 20x + 50

When their earnings are equal, we have:

20x + 50 = 15x + 100

Collect like terms

20x - 15x = 100 - 50

Evaluate the differences

5x = 50

Divide both sides by 5

x = 10

Hence, their total charges would be equal after working for 10 hours

Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long peices. How many strips can Bruce cut from his rope
dybincka [34]

Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.

The length of the rope = 21 feet

the length of each strip = \frac{1}{5}

We need to cut the rope 21 feet into \frac{1}{5} strips

To find the number of strips we divide 21 feet by the length of the strip

\frac{21}{\frac{1}{5}} = 21 * \frac{5}{1} = 105

105 strips can Bruce cut from his rope.

Given that ∠CEA is a right angle and bisects ∠CEA, which statement must be true?
loris [4]
Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.
<span>m∠CEB = 45°</span>

Select the polynomial that is a perfect square trinomial.
alexdok [17]

Answer:

Option D. It's a perfect square trinomial.

Step-by-step explanation:

(a) 36x² - 4x + 16

= (6x)² - 2(2x) + (4)²

It's not a perfect square trinomial

(b) 16x² - 8x + 36

= (4x)² - 2x(4x) + (6)²

It's not a perfect square trinomial

(c) 25x² + 9x + 4

= (5x)² + 2(\frac{9}{2}x) + (2)²

It's not a perfect square trinomial

(d) 4x² + 20x + 25

= (2x)² + 2(10x) + (5)²

= (2x+5)²

It's a perfect square trinomial.
