the perimeter of a semicircle is 5.14 millimeters what is the semicircle diameter

Answers

Answer 1

Answer:

2 mm

Step-by-step explanation:

let the radius of the semi-circle be r

Then,

length of curved portion = 1/2 x circumference = (1/2) (2)(π)r = πr

length of straight portion = diameter of circle = 2r

Hence, we can write an expression for the perimeter

Perimeter = length of curved portion + length of straight portion

Perimeter = πr + 2r

Perimeter = (π + 2)r

since we are given the perimeter = 5.14, assuming that π=3.14, our equation becomes:

5.14 = (3.14 + 2)r

5.14 = 5.14 r

r = 5.14 / 5.14 = 1

Hence, diameter = 2r = 2(1) = 2 mm

Given the following formula, solve for r c=2rr

Answers

Answer: I’m assuming you accidentally typed r a second time so.

c=2r, swap sides.
2r=c, divide both sides by 2.
r=1/2c, that should be your answer

Answer:

[tex] \sqrt{ \frac{c}{2} } = r[/tex]

Step-by-step explanation:

c=2rr

c = 2r×r

c= 2r²

c/2= r²

[tex] \sqrt{ \frac{c}{2} } = \sqrt{ {r}^{2} } \\ \\ \sqrt{ \frac{c}{2} } = r[/tex]

A manufacturer of game controllers is concerned that their controller may be difficult for left handed users. They set out to find lefties to test. About 13% of the population is left handed. If they select a sample of five customers at random in their stores, what is the probability of each of the following outcomes?
a. The first lefty is the fifth person chosen
b. There are some lefties among the 5 people
c. The first lefty is the second or third person
d. There are exactly 3 lefties in the group
e. There are at least 3 lefties in the group
f. There are no more than 3 lefties in the group

Answers

Answer:

a)0.074

b)0.502

c)0.2114

d)0.0166

e)0.01790

f)0.9987

Step-by-step explanation:

Probability of being left handed = 0.13

Probability of being not left handed = 1-0.13 =0.87

They select a sample of five customers at random in their stores

a. The first lefty is the fifth person chosen

Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]

b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]

c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]

d)

[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]

e)

[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]

f)

[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]

[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]

__________________________________________________

      " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 .   That value is the unit rate. "

__________________________________________________

Step-by-step explanation:

__________________________________________________

Note that the "unit rate" is the term that refers to:

a "quantity" / or "quantitative value" ;  

      →  of some type of "countable units"

{e.g. "currency"  — [such as:  dollars, cents,  pounds] ; "distance/length/ width/ height" — [such as:  miles, kilometers, meters, centimeters, yards, feet, inches] ;  pieces of fruits — [such as:  number of apples;  cans of soda, number of red dresses] ;  

__________________________________________________

per "single unit" of something — {e.g. per hour; per minute; per mile; per ounce; per hour; per dollar, per kilometer, per day, per week.

  {e.g.

            →    " 3 apples eaten  per [single] apricot eaten" ;

            →  " 46 miles per hour.

            →   " 8.3 cents per oz."  ;

            →  " 5 Liters of soda per dollar " ;

            →   " 2.3 grams per mole " ;

            →  " 4.6 mg solute / kg of solvent " ;  

            →  " 5 km / hr " ;  {that is:  " 5 km per hr " } .

            →  " 3 yds. per [single] square inch."

            →  " 35 parts per hundred" ; {that is:  " 35 percent" ; or: " 35 % " . } .

            →    " ... The cilantro is on sale for 33 cents per bundle ...} ."

  →  ... to provide a few examples.  

__________________________________________________

    On on Cartesian plane graph,  the  "x-axis" is located on the "horizontal axis" that represents the "independent variable" (or, at times, the "experimental value" — which can be manipulated — or "controlled" —or  be subjected to being "manipulated" / "controlled" / or, "selected".

  The "y-axis" is located on the "vertical axis" that represents the "dependent variable" (or, at times, the "control value") that cannot be "manipulated" / controlled/ or "selected" / since it represents the "y-value" of the corresponding coordinate to which the "x-value" happens to corresponds to at the given value for "x" .

  So, if the "unit rate" represents the "single unit rate" ;  we look at "x = 1 " ;  since we are "choosing" this particular "single" rate of per "single" (i.e. "1" ) ; so we do not have a choice in what "y-value" of the particular graph to select.  We can control the fact that we are "choosing" to find the "unit" rate, so we select the "independent variable" , "x = 1 " . We then examine the "corresponding y-value" that happens to exist when "x = 1 " .

{Note that we have "no control" over what that "y-value" is ; at the: "[point which:  " x = 1 .] . "

_________________________________________________  

→  As such, that "y-value" [insert that numeric "y-value" ;                        followed by the units represented by the "y-axis" ] ;

           per  " 1 " [insert "single unit" represented by the "x-axis" ] ;

_________________________________________________    

          →   is the:  "unit rate" .

__________________________________________________

So:  

   The correct answer is:    [A]:  

__________________________________________________

    " Look at the graph of the relationship.  Find the y-value of the point that corresponds to x = 1 .   That value is the unit rate. "

A debit or ATM card allows you to make payments both offline and online.

When a debit card is used to make a transaction, the money is withdrawn directly from the customer's account. In general, using credit cards to pay for online purchases is the safest and most secure alternative. The online security features of credit cards, such as fraud monitoring and encryption, secure your accounts and personal information.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If there are 6 cans in a pack, and you bought 16 packs.

Total cans.

= 6 x 16

= 96 cans

If you drank 9 cans, then the number of cans left.

=  96 - 9

= 87 cans.

Therefore,

There are 87 cans of cola left.
