Answer:

Angle STR = 78°

Step-by-step explanation:

So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:

20x + 12 + 10x + 33 = 180

Combine like terms

30x + 45 = 180

Subtract 45 from both sides

30x = 135

Divide both sides by 30

x = 4.5

Now we know the value of x. We just need to plug it into angle STR's given value:

10(4.5) + 33 = angle STR

45 + 33 = angle STR

78° = angle STR

Solve the inequality: (x+3)(x−4)<−12
melamori03 [73]

Answer:

0<x<1

Step-by-step explanation:

(x+3)(x−4)<−12

FOIL

x^2 -4x+3x -12 <-12

x^2 -x -12 <-12

Add 12 to each side

x^2 -x -12+12 <-12+12

x^2 -x <0

Factor out an x

x(x-1) <0

Using the zero product property

x(x-1) =0

x=0  x-1=0

x=0  x=1

Check the ranges

x<0

x(x-1) <0        

- * - >0

False

0<x<1

x(x-1) <0        

+ * - <0

True

x>1

x(x-1) <0        

+ * + >0

False

In scientific notation
mrs_skeptik [129]

(3.9 \times  {10}^{ - 3}) + 0.0026 =

(39 \times  {10}^{ - 4}) + (26 \times  {10}^{ - 4}) =

39 \times  {10}^{ - 4} + 26 \times  {10}^{ - 4} =

Factoring \:  {10}^{ - 4}

{10}^{ - 4} \times (39 + 26) =

65 \times  {10}^{ - 4} =  6.5 \times  {10}^{ - 3}
