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.

Answer: 50 Degress

Step-by-step explanation: As we can see in the photo, this is half of a circle which is equal to 180 degress, because a full circle is 360 degress.

We already have the first two angles completed, so to make things simple we will add them

65 + 65 = 130

Next since we know the total of all three angles is 180 degress we will subtract that by the angles we already are shown, which is a total 130 degress

180 - 130 = 50

So angle C is 50 degress

Answer:

(A) 24+72+48

(B) Sarah sold 24 meals and Samir sold 72 and SungSo sold 48.

(C) 144 is how many they sold in all.

Step-by-step explanation:

Samir sells 3 times as much as Sarah, so he sells 72. SungSo sells twice as much as Sarah so he sells 48. Sarah sells 24.

Using the Addition Standard Algorithm I calculated that they sold 144 deli meals.

Answer: Area = 4 because 8 x 1/2 = 4

Answer:

Only the first option. 10-2

Step-by-step explanation:

2.75 x 2 + 3 x 1.5 - 2

= 8

10 - 2 = 8

2.75 x 2 + 2.25 = 7.75

8.5 x 1.5 - 2 = 10.75

5.5 + 3 x(-0.5) = 4

Therefore, Only the first option is correct.

Answer:

Sarah=S

SungSo=U

Semir=E

1.

A. (2+S)+(3s)+S

B. SungSo sold 26 meals and Semir sold 72 meals.

C. In total the meals sold are 122 meals. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. (2n-5)*18

B. (450/18-5)/2=10

C. 25 miles

D. (25*18-72)/18=21

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.

Step-by-step explanation:

1.

A. The equation is (2+S)+(3s)+S since Sarah=S, SungSo sold 2 more meals than Sarah, and Semir sold 3 times as many meals as Sarah.

B. SungSo sold 26 meals and Semir sold 72 meals because if you plug it in with the equations, (2+24)=26 meals for SungSo and (3*24)=72 meals for Semir.

C. In total the meals sold are 122 meals since (2+24)+(3*24)+24=122. The commutative property plays a role in this problem since it doesn't matter which order you add them in. The associative property also shows that it doesn't matter in which way you group the addends.

2.

A. The answer is (2n-5)*18 because Sarah walked 5 miles less than twice the number of miles that Semir walked, n.

B. The answer is (450/18-5)/2=10 because then you would need to use the same equation as you used in part A, but use it inversely since now you have how much Sarah collected instead of how many miles Semir walked.

C. Sarah walked 25 miles since she earns $18 per mile and she earned $450, so 450/18=25.

D. The answer is (450-72)/18=21 because he collected the same amount of money as Sarah which is 450. He also recieve a donation of $72 from his Grandmother, so you would subtract that and then divide it by 18 to find how many miles he walked.

3. In total, SungSo, Sarah, and Semir have raised $1,080 and sold 122 meals in total. SungSo sold 26 meals, Semir sold 72 meals, and Sarah sold 24 meals. SungSo raised $378, plus the $72 donation which brings the money to $450, Semir raised $180, and Sarah raised $450.

82 7/8 I think

Step-by-step explanation:

You multiply first 8 1/2 and 3 1/4 and then multilpy that answer with 3

Answer:

82  7/8

Step-by-step explanation:

Volumes is length x width x height

L 8 1/2 x W 3/1

change 8 1/2 mixed fraction to an improper fraction of 17/2

17/2 x  3/1 =  17x3/2x1 = 51/2

Now we times 51/2 x height 3 1/4

change 3 1/4 mixed fraction to an improper fraction 13/4

51/2 x 13/4 =  51x13/2x4 = 663/8

Now they want your answer to be a simplified mixed fraction

How many times can  8 go into 663 without going over?  

82 times since 82 x 8 = 656

The remainder left over is 663/8 - 656/8 = 7/8

So your answer is 82 7/8.  You cannot simplify 7/8 any farther.

You can also divided 663 by 8, just remember to list your remainder as a fraction of the eighths

Answer:

x > 7

Step-by-step explanation:

-8x+40>-16

You do 40 minus 40, and that cancells it out, then you  do -16 minus 40, wich gives you -56, then, you do -1 divided by -8, wich, again, cancels it out, and finally, do -56 divided by -8 wich gives you 7, so, x=7.

Answer:

-7/3 is c

-2.9 is a

-2 5/8 is b

Step-by-step explanation:

-5/2 = -2.5

-7/3 > -2.5, so -7/3 is c

-6/2 = -3

-2.9 is very close to -3, so -2.9 is a

-2 5/8 is just a little less that -2.5, so -2 5/8 is b

Step-by-step explanation:

Answer:

$1,169.30

Step-by-step explanation:

The answer is $1,169.30 since 621.60-600=21.60, meaning that in the past 4 years, Chelsea has gained $21.60. Then you would do 21.60/4 to find how much per year, which would get you $5.40. Then you need to find the interest rate by doing 5.40/600 since she started out with 600. 5.40/600=0.009. Then you would turn it into percentage by multiplying it by 100, to get 0.9%. Now, since she's deposited $1,100 instead, you would do 0.9*1,100, and then you would get 990, then you would have to divide it by 100 and get $9.90. That means she gains $9.90 per year. Since she'll have it for 7 years, you need to do 9.90*7=63.90. Then you would add it to 1,100 to get $1,169.30
