An intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.

Answers

The length of an arc is the distance between the endpoints of the arc.

The central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]

The given parameters are:

[tex]\mathbf{l = 19yd}[/tex] --- length of the arc

[tex]\mathbf{r = 4}[/tex] -- radius of the circle

The length of an arc is calculated as:

[tex]\mathbf{l =r\theta}[/tex]

Divide both sides by r

[tex]\mathbf{\theta = \frac lr}[/tex]

Substitute known values

[tex]\mathbf{\theta = \frac{19}4}[/tex]

[tex]\mathbf{\theta = 4.75\ radians}[/tex]

Convert to degrees as follows:

[tex]\mathbf{\theta = 4.75 \times \frac{180}{\pi}}[/tex]

[tex]\mathbf{\theta = 4.75 \times \frac{180}{3.142}}[/tex]

[tex]\mathbf{\theta = 272.16^o}[/tex]

Hence, the central angle is: [tex]\mathbf{4.75\ rad}[/tex] or [tex]\mathbf{272.16^o}[/tex]

The tens digit is twice the units digit. Reverse the digits, add 2 and the new number is 34 less than the original number. Find the original number.

Answers

Answer:

Step-by-step explanation: X and Y represent the digits.

The tens digit is twice the units digit.

The digit in the Tens place has 10× its base value, so we can set up equations to model the information given.

10x +y 10y +x are Original & Reversed numbers

X = 2y means the Tens digits is twice the units digit.

10y + x +2 = 10x +y - 34 models the statement: The reversed number plus two is 34 less than the original number.

Substitute 2y for x to solve for y

10y +2y +2= 10(2y) + y -34

Distribute and combine like terms

12y + 2 = 20y +y - 34

34 +2 = 21y -12y

36 = 9y Divide both sides to find the value of y.

4 = y

X = 2(4) Substitute 4 for y to find x

X = 8

Original number: 84 Reversed number: 48

Substitute into equation model

48 +2= 84 -34

The  statements describe America’s workforce during World War II are:

Hundreds of thousands of women signed up for the US military. Women were hired to do jobs traditionally done by men. New laws ended discrimination in the government and defense industries. More African Americans and other minority workers were able to find jobs.

What happened to the American labour force during World War II?

Labor shortages were caused by military and economic development. To close the gender gap, the government and industry encouraged women to enter the labour force. While the majority of working women continued to work in more traditional jobs such as waitressing and teaching, millions took better-paying jobs in military manufacturers.

By the end of the war, over six million women had entered the labour sector, and by 1945, they accounted for about 37 percent of the workforce, up from only 27 percent in 1940.

Their contributions to the war effort were critical. Women accounted up 65 percent of all employees in the aerospace industry alone.
