Answer:

x<−7 and x>−11

Step-by-step explanation:

Let's solve your inequality step-by-step.

5(|x+9|)<10

Step 1: Divide both sides by 5.

5(|x+9|)/5 < 10/5

|x+9|<2

Step 2: Solve Absolute Value.

|x+9|<2

We know x+9<2 and x+9>−2

x+9<2(Condition 1)

x+9−9<2−9(Subtract 9 from both sides)

x<−7

x+9>−2(Condition 2)

x+9−9>−2−9(Subtract 9 from both sides)

x>−11

Carter's salary is $1.1138⁶ more than Salma's salary.

To perform the difference, we need to be able to take a common factor.

We know that Salma's salary is $6.2×10⁴

While Carter's salary is $1.2×10⁶

To get the same common factor, 10⁴, we can divide and multiply Carter's salary by 100, so we get:

[tex]1.2*10^6*\frac{100}{100} = (1.2*100)*(10^6/100) = 120*10^4[/tex]

Then Carter's salary is $120*10⁴

The difference between Carter's and Salma's salaries is:

$120*10⁴ -  $6.2×10⁴ = $113.8*10⁴

If we return to the scientific notation, we get:

$113.8*10⁴  = $1.1138⁶

This means that Carter's salary is $1.1138⁶ more than Salma's salary.

The value of the missing triangle sides and angles are XY = 20.9, YZ = 12.4 and ∠Y = 119°

An equation is an expression that shows the relationship between two or more numbers and variables.

Sine rule is used to show the relationship between the sides and angles of a triangle.

In the triangle XYZ:

∠X + ∠Y + ∠Z = 180° (sine rule)

22 + 39 + ∠Y = 180

∠Y = 119°

Using sine rule:

XY / sinZ = XZ / sinY

XY / sin(39) = 29 / sin(119)

XY = 20.9

Also:

YZ / sinX = XZ / sinY

YZ / sin(22) = 29 / sin(119)

YZ = 12.4

The value of the missing triangle sides and angles are XY = 20.9, YZ = 12.4 and ∠Y = 119°

Let's solve:

   ⇒ Area = 12 * 11 = 132 in²

Answer: 132 in²

Hope that helps!

#LearnwithBrainly

Answer:

132 inches squared

Step-by-step explanation:

Area is 132 inches squared

Method 1:

Area of parallelogram = base x height = 11inches x 12 inches = 132 inches squared

Method 2:

Move the triangle divided by the dotted line on the right to the left.

It becomes a rectangle of 11 inches by 12 inches. 11 inches x 12 inches = 132 inches squared.

Mauricio takes 24 hours, and Alyson takes 24/5 hours if the Mauricio does a job in 6 hrs less time than Alyson.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let x and y be the time to take the job for Mauricio and Alyson respectively

1/x = 1/y - 1/6 ..(1)

1/x + 1/y = 1/4 ..(2)

After solving the equations:

[tex]\rm \dfrac{1}{\dfrac{6y}{6-y}}+\dfrac{1}{y}=\dfrac{1}{4}[/tex]

y = 24/5 hours
