Paul is making a ball-toss game for his club booth at the fair. He wants to make the circumference of the holes at least 3 inches greater but not more than 4 inches greater than the circumference of the ball. One person suggests that Paul can make the diameter of the hole 1 inch greater than that of the ball. Another suggests the diameter should be 2inches greater. Which suggestion should Paul choose? Explain

Answers

Answer:

Paul can make the diameter of the hole 1 inch greater than that of the ball

Step-by-step explanation:

we are going to assume a diameter of the hole has 6in

the radius of the ball is 3in

we looking at a range of the hole greater by (3<4)

we know that the circumference of a circle is given as

the circumference of the ball is

C=2πr

C=2*3.142*3

C=18.85in

The circumference of the hole is ( 1 inch greater )

C=2πr

say the diameter is 6in plus 1in = 7in

the radius =3.5in

C=2*3.142*3.5

C=21.99

compare with the ball the difference is 21.99-18.85

=3.14 which is in the range

The circumference of the hole is ( 2inches greater. )

C=2πr

say the diameter is 6in plus 2in = 8in

the radius =4in

C=2*3.142*4

C=25.13in

compare with the ball the difference is 25.13-18.85

=6.28 which is out of  the range

Consider this equation.


7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)



Mia solved the equation and determined that m = 2. Is she correct?

She is incorrect because when substituting 2 for m the result was a true statement.

She is incorrect because when substituting 2 for m the result was a false statement.

Answer:

If you mean that 134 degrees = (9q - 8), the answer is: q = 15.78 degrees

Step-by-step explanation:

134 degrees = 9q - 8

142 = 9q

142/9 = q

15.78 = q

q = 15.78 degrees

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28

Answers

Answer:

y = -1/4x + 4

Step-by-step explanation:

x+4y=28

4y = -x + 28

y = -1/4x + 7

slope m = -1/4

Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.

y = mx +b

2 = -1/4(8) + b

2 = -2 + b

b = 4

Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.

y = mx + b

y = -1/4x + 4

okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.

Answer:

-4/3

use the slope formula (y2 - y1)/(x2 - x1)

Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made another 8 ft of sausage links and used 12 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night?

Answers

Answer:

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Step-by-step explanation:

Amount of  sausage links made on Friday morning = 8 ft

Amount of  sausage links used on Friday night = 4 ft

Amount of  sausage links remaining = 8 - 4 = 4ft           (i)

Amount of  sausage links made on Saturday morning = 8 ft         (ii)

So,

Total amount of  sausage links = 8 + 4 = 12 ft   (from (i) and (ii) )

Amount of  sausage links used on Saturday night = 12 ft

Amount of sausage links remaining = 12 - 12 = 0 ft

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Keiko has a 20% copays for hospital visits after paying her deductible. Assuming she already paid her deductible earlier in the year, how much will she pay (copay) for a hospital bill of $3,291?

A. $328.90
B. $658.20
C. $2,632.80
D. $1,645.50​

Answers

Answer:

$658.20

Step-by-step explanation:

Money paid in deductible = $3,291

percentage of money to be co-paid = 20% of Money paid in deductible

Thus, she has to 20 percent more which will be 20/100 th part of money paid in deductible.

Solving it we have

Money to be co-paid =  20% of $3,291 = 20/100 * $3,291 =  $658.20

Thus, Keiko will  pay (copay) $658.20 for the hospital bill

The following figures are not drawn to scale but AB and CD are straight lines. Find x.

Answers

Answer:

uh I think x=25°

Step-by-step explanation:

2x+60°=110°(vertically opposite angles are equal)

2x=110°-60°

2x=50°

x=50°÷2

x=25°

A straight line equals 180 so O =70 and so does the angle across from it to add the knowing angles and you’ll get 310. Subtract this from 360 since that is the degree of a circle and get 50. So then your equation is 50= 2x and you divide and get x=25

For example, it seems likely that women, not men, invented gardening, as well as created the first baskets and pottery. This makes sense for two reasons.
