Answer 1

Answer:

Angle 3 is 72

Angle 4 is 18

Angle 5 is 90

Angle 6 is 72

Step-by-step explanation:

Sum of straight angle is 180

So 180 = (90+18+x) for angle 3

Answer 2
90+18 gives you 108 and since a straight angle is 180, you have to subtract 108 from 180 which gives you 72.

The range is 13. You see that the box plot extends all the way to 83 with the straight line and all the way down to 70 with the other line. This would mean 83 and 70 are the largest and smallest values, and 83 - 70 equals 13.

4. The radius of a circular hat is 3.7 inches. Find the circumference. Use 3.14 for π.

Answers

Answer:

C = 2(3.7π) = 7.4π = 23.248 inches

Using 3.14 for π:

C = 2(3.7)(3.14) = 7.4(3.14) = 23.236 inches

Step-by-step explanation:

y=mx+b is the slope intercept form of a line.

you need to find m and b

m is the slope (rise over run) in this case it is 1 up, then over 2.

and b is the Y intercept. or in other words, the spot where the line cuts through the y-axis(vertical axis). in this case, it is -2.

A cylinder has a height of 17 centimeters and a radius of 13 centimeters. What is its volume?
Use a 3.14 and round your answer the nearest hundredth.

Answers

Answer:

Check explanation

Step-by-step explanation:

There are two ways to solve this, I'm not sure which way is the correct one:

1. Solving with 3.14

V=πr²h

V=(3.14)(13)²(17)

V=(3.14)(169)(17)

V=(3.14)(2873)

V=9021.22

9021.22 rounded to the nearest hundredth is 9021.22

2. Solving with π (I used a calculator to solve with π)

V=πr²h

V=π(13)²(17)

V=π(169)(17)

V=π(2873)

V=9025.79569376

9025.79569376 rounded to the nearest hundredth is 9025.8

The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Answer:

V=9021.22

Step-by-step explanation:

The formula for a cylinder is πr(r)(h)

r=13

h=17

π13(13)(17)

π169(17)

π2873

π=3.14

3.14(2873)

9021.22

V=9021.22

2. x≥50

3. x≤8

4. x≤75

Answer:

1. <

2. ≥

3. ≤

4. ≤

Step-by-step explanation:

since the first one says “less than” the opening of the sign is pointed towards the 14

for the second it says “at least” so it has to be 50 dollars or more

for the third it is “at most” 8. that means that the highest number is 8 so there can’t be a number greater than that. but they can be less

for the fourth it’s “no more” than 75 degrees so that means it has to be 75 degrees or less. It can’t be more

For what value of A is the graph of Ax+6y = 12 perpendicular to the graph of 2x−3y = 4?

Answers

Answer 3x explanation

The value of A for the two graphs will be 9.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

The two equations are Ax+6y = 12 and 2x−3y = 4. The value of A will be calculated as,

2x−3y = 4

y = 2/3x - 4/3

Ax+6y = 12

y = -A/6x +2

The slope of one graph will be inverse and the opposite to the other graph for the line to be perpendicular,

-3 / 2 = -A / 6

A = 9

Being self-employed, he lacked health insurance. One day on the job, Rodney suffered a heart attack and was hospitalized for a week. As a result, he owed more than $100,000 in hospital and medical bills to the hospital. After the heart attack, Rodney could not work in his physically demanding line of work, and his business suffered dramatically. The bills and mortgage payments kept piling up, and Rodney was sinking fast. On top of the medical bills and mortgage, he owed thousands of dollars to multiple companies and creditors.
