Answer:

#1 = 10.71% decrease (not sure if you should write -10.71%)

#2 = 49.29% decrease (-49.29%) (-49.30% rounded)

#3 = 5.4% increase

#4 = 34.26% decrease (-34.26%. -34.27 if your teacher wants it rounded.)

Step-by-step explanation:

Original:28

New:25

Increase ÷ Original Number × 100.

28-25 =3

3/28 = 0.1071

0,1071*100= 10.71

Original:21.2

New:10.75

21.2-10.75= 10.45

10.45/21.2 = 0.4929

0.4929*100 = 49.29 (49.30)

Original:37

New:39

difference = 2

2/37 = 0.054

0.054*100 = 5.4

Original: $4.29

New:$2.82

4.29-2.82 = 1.47

1.47/4.29 = 0.3426

0.3426*100 = 34.26 (34.27)

Hope this helps! Have a great day! Also, let me know if it is correct.

Answer:

Step-by-step explanation:

Emma is making two different kinds of cookies for a cookie party she will be attending. She needs 2 and 2/3 cups of sugar for the first recipe and 1 and 1/4 cups of sugar for the second recipe. Emma thinks she will have enough sugar but she isn't quite sure. She knows that her full 2 pound bag of sugar says it contains 4 and 1/2 cups of sugar. Determine the exact difference between the amount of sugar Emma has and the amount of sugar she needs for the recipes.) Emma's mom brought home another 2 pound bag of sugar (4 and 1/2 cups) and wants to make fudge to take to work. Her mom will need 2 and 1/6 cups of sugar. Write a numerical expression that could be used to determine exactly how much sugar will be left over from the two bags of sugar after Emma bakes cookies and her mom makes fudge

The question is below thanks

Paha777 [63]

Answer:

FH ~ 10.02

Step-by-step explanation:

1. Approach

One should first find the circumference of the given circle. Then one should find how large the fraction of the circumference one is supposed to find is. Finally, one should multiply the fraction of the circumference one is supposed to find by the total circumference.

2. Circumference of the circle

The formula for circumference is;

$2r$ π

Substitute in the given values;

It is given that the radius is, hence

2 (7) π

14π

3. Find the fraction of the circumference one is supposed to find

It is given that the angles over the measure of the total degrees of angles in a circle are equal to the arc surrounding the angles of the circumference. Essentially;

$\frac{angles}{360}=\frac{arc}{circumference}$

Substitute in the given information and solve;

$\frac{82}{360}=\frac{arc}{14pi}$

arc = $\frac{41}{180}*14pi$

arc = $\frac{287}{90}*pi$

arc ~ 10.02

What is the constant of proportionality?

Mars2501 [29]

Answer:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
