Answer: x=12

Step-by-step explanation:

we know that sum of a triangle is 180 degrees

one angle is 90 degree

the sum will be 90+(2x+1)+(5x+5)=180

substract 90 from both sides

2x+1+5x+5=180-90

7x+6=90

7x=90-6

divide by 7

x=12

Jacob is a plumber. Due to increased material costs, he puts all his prices up by 7%. He now chargers R320 per hour for her serv
Lorico [155]

Answer:

R290.1

Step-by-step explanation:

Let

x = charge before he put his prices up

New charge = R320

Percentage increase in price = 7%

x + 7% of x = 320

x + 0.07 * x = 320

x + 0.07x = 320

1.07x = 320

x = 320/1.07

x = 299.06542056074

Approximately

x = R290.1

Charge before he put his prices up = R290.1

What are the domain and range of this function?
Arlecino [84]

Answer:

Correct answer:  The third answer is correct

Step-by-step explanation:

The domain of each function is defined by observing the behavior of the function from left to right by following the growth of numbers on the x axis of real numbers.

In the same way, the range of each function is defined by observing the behavior of the function from the bottom y axis upwards by following the growth of numbers on the y axis of real numbers.

The given function extends from negative infinite to positive infinite on the x axis and that is the domain of this function.

The minimum of a given function is 4, which means that the function exists from 4  upwards and that is the range of the function.

Domain; all real numbers or x ∈ ( -∞ , + ∞)

Range:  ( y ≥ 4 )

Find r<br> 25= r•r•8<br> hurry go fast please
ELEN [110]

Answer:

r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}
