For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. Whatsize buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to
represent pi.)
A. 2.35 centimeters
B. 1.14 centimeters
C. 5.14 centimeters
D. 3.69 centimeters

Answers

Answer 1

Answer: answer is A.2.35cm
c=pid
circumstances is 7.38 cm so
7.38=3.14d
divide both sides by 3.14
7.38/3.14=3.14x/3.14
2.35=×

Answer 2

Answer:

IT's A. 2.35 centimeters

Which point in a triangle is equidistant from the vertices of the triangle?

Answers

Since a point equidistant from two points lies on the perpendicular bisector of the segment determined by the two points, the circumcenter (labeled below) is the point of concurrency of the three perpendicular bisectors of each side of the triangle.

Answer: The point of intersection of the perpendicular bisectors. On plato its C.

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x?Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67
Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67

Answers

Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6

The ordered pairs are: (100, 135) and (500, 375)

The first number is the number of minutes of usage and the second number is the charge of the month.

The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6

Answer:

Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6

Step-by-step explanation:

Data

x: total minutes used

y: total monthly charges

x | y

100 | $135

500 | $375

That can be expressed as coordinates (x, y), so the points are (100, 135) and (500, 375).

The slope is computed with two points (x2, y2) and (x1, y1) as follows:

slope = (y2 - y1)/(x2 - x1)

Replacing with data

slope = (375 - 135)/(500 - 100) = 0.6

Solve for x. -ax+4b>9

Answers

-ax+4b>9
-ax>9-4b
-x>(9-4b)/a
x<-(9-4b)/a
x<(4b-9)/a

Answer: x<-(9-4b)/a or x<(4b-9)/a

Let's solve for a.(−a)(x)+4b>9Step 1: Add -4b to both sides. −ax+4b+−4b>9+−4b −ax>−4b+9
Step 2: Divide both sides by -x. −ax−x>−4b+9−x a<4b−9x

When Arjun makes hot cocoa, he adds 20 mL 20 mL20, start text, space, m, L, end text of chocolate syrup for every 3 33 ounces of hot water. Arjun's brother, Eli, adds 45 mL 45 mL45, start text, space, m, L, end text of chocolate syrup for every 6 66 ounces of hot water. Which hot cocoa is more chocolatey? Choose 1 answer: Choose 1 answer: (Choice A) A Arjun's hot cocoa (Choice B) B Eli's hot cocoa (Choice C) C The two cocoas are equally chocolatey.

Answers

Answer:

(Choice B) B Eli's hot cocoa

Step-by-step explanation:

Arjun makes hot cocoa, he adds 20 mL of chocolate syrup for every 3 ounces of hot water.

Ratio of chocolate syrup to hot water = 20 : 3

= 20 / 3

= 6.67

Eli adds 45 mL of chocolate syrup for every 6 ounces of hot water.

Ratio of chocolate syrup to hot water = 45 : 6

= 45 /6

= 7.5

The ratio of Eli's chocolatey hot cocoa is more than Arjun's chocolatey hot cocoa.

The correct answer is B Eli's hot cocoa

Answer: The answer is the B Eli's hot cocoa .
