Answer:
Those areas are: A 1 = 12, A 2 = 19
Step-by-step explanation:
The area of shape 1 : it consists of 1 square + 4 right triangles
Area of the square: A = a², area of the triangle: A = 1/2 · a · h
A 1 = 2² + 4 · 1/2 · 2 · 2 = 4 + 8 = 12
The area of shape 2 : it consists of 2 isosceles triangles
A 2 = 1/2 · 2 · 4 + 1/2 · 6 · 5 = 4 + 15 = 19
Answer:
$7.58/lb
Step-by-step explanation:
raw roast: $5.99 per lb
deli roast: $2.99 for 100g
We know the price per lb of the raw roast.
Let's find the price per lb of the deli roast.
1 lb = 454 grams
454 grams / 100 grams = 4.54
1 lb is 4.54 times 100 g
If we multiply the price of 100g of deli roast by 4.54, we get teh price per lb.
$2.99/lb * 4.54 = $13.57/lb
raw roast: $5.99/lb
deli roast: $13.57/lb
difference in price of 1 lb: $13.57 - $5.99 = $7.58
Answer: $7.58/lb
The set of integers is not closed under the operation of division because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities
<h3>How to determine the true statement?</h3>
Integers are numbers without decimal points
When integers are divided, the possible results are:
The decimal and the zero possibilities imply that the set of integers is not closed under the operation of division
This is so because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities

Answer: 9 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
Surface area if a cylinder (S)= 2 π r2 + 2 π r h
Where r is the radius and h is the height
Diameter is equal to 2r , so in our case:
14 =2r
r = 14/2 = 7 meters
Replacing with the values given and solving for h:
224 pi = 2 π 7^2 + 2 π 7 h
224 π - 2 π 7^2 / 2 π 7= h
703.71 -307.87 /43.98 = h
9 = h
