Krystal’s poster project for reading class is 2 feet high and 1 1/2
2 feet wide. Her friend Victoria’s poster is 4 feet high and 1 1/2 feet wide. How many times larger is the area of Victoria’s poster? Draw a model on the grid paper, and show your multiplication work here.
Answers
Answer:
The area of Victoria's poster is twice the area of Krystal's poster.
How compare the areas of two similar posters
The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas (r_{A}rA ), no unit, is defined by the following formula:
r_{A} = \frac{w_{V}\cdot h_{V}}{w_{K}\cdot h_{K}}rA=wK⋅hKwV⋅hV (1)
Where:
w_{V}wV - Width of Victoria's poster, in feet.h_{V}hV - Height of Victoria's poster, in feet.w_{K}wK - Width of Krystal's poster, in feet.h_{K}hK - Height of Krystal's poster, in feet.
If we know that h_{V} = 4\,fthV=4ft , w_{V} = 1.5\,ftwV=1.5ft , h_{K} = 2\,fthK=2ft and w_{K} = 1.5\,ftwK=1.5ft , then the ratio between the two areas is:
r_{A} = \frac{(4)\cdot (1.5)}{(2)\cdot (1.5)}rA=(2)⋅(1.5)(4)⋅(1.5)
r_{A} = 2rA=2
The area of Victoria's poster is twice the area of Krystal's poster. \blacksquare■

Could anyone please help me with these 3 questions? Will give brainiest. PLEASE SHOW ALL WORK!
1. Semir, Sarah, and SungSo decided to raise money for a local homeless shelter by working in a local deli. The deli agreed to donate to the shelter a portion of the profits from each meal the three sold. Semir sold 3 times as many meals as Sarah. SungSo sold 2 more meals than Sarah.
a.Write an expression for the number of meals that each sold.
b. If Sarah sold 24 meals, how many meals did Semir and SungSo each sell?
c. How many meals did the three sell in all? Explain how to use the commutative property and the associative property of addition to make finding the sum easier.
2. The three decided to participate in a walkathon to raise additional money for the shelter. Sarah walked 5 miles less than twice the number of miles that Semir walked. They each collected $18 in pledges for every mile they walked.
a.Let n represent the number of miles Semir walked. Write an expression for the number of miles Sarah walked and an expression for the amount of money Sarah collected in pledges.
b.Write and solve an equation to find how many miles Semir walked if Sarah collected $450 in pledges.
c. How many miles did Sarah walk?
d. SungSo also collected $18 in pledges for every mile he walked. In addition, his grandmother gave him a $72 donation. He collected the same amount of money as Sarah did. Write and solve an equation to find the number of miles SungSo walked.
3. Write a memo to the director of the shelter describing the total donation the three friends are sending and how it was raised. Be sure to include how much each student raised individually.
Answers
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.

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:
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: 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

(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.
h=r/3
o=h+2
b.) Semir sold 72 because 24x3=72
Sungso sold 26 because 24+2=26
c.) in total they sold 24+72+26 we can just add the two of them with fitting second digits that being 24+26 because it will equal 50 which is an easy number to work with then we can just do 50+72 which is 122

$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
