Dena wants to make a birdhouse with the leftover wood. she needs 105 3/5 centimeters of wood for the birdhouse. write and evaluate an expression to determine how much how much more wood will be needed. PLEASE HELPPP
Answer:
Step-by-step explanation:
hi sorry if this is wrong but the answer is Dena wants to make a birdhouse with the leftover wood. but She needs 105 3/5 of wood
Dena needs 1.15 centimeters more of wood is needed to make the birdhouse.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood.
We can represent each piece of wood with a fraction and then add all the fractions.
The total length of wood can be represented as:
12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)
To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:
12.7 + 26 3/10 = 12.7 + 26.3
15 4/5 = 15 + 0.8
21 1/4 = 21 + 0.25
3/10 = 0.3
4/5 = 0.8
So, the expression becomes:
12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45
Therefore, the total length of wood left over is 104.45 centimeters.
B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:
105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15
Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

least to greatest 11/20,1/2,0.51
Answer:
1/2, 0.51, 11/20
Step-by-step explanation:
11/20 = 0.55
1/2 = 0.50
0.51
Least to greatest ---> 1/2, 0.51, 11/20
Answer:
1/2, 0.51, 11/20
Step-by-step explanation:
To find out which one is least to greatest, I suggest turning all the numbers into decimals. In order to do this you need to divide the 11 by 20 on a calculator which equals 0.55. Then, we already know that 1/2 = 0.50, and that leaves us with 0.51. So, know we order them.

The Big Top tent at the traveling circus has a cylindrical wall that is 30 feet tall and has a diameter of 72 feet. A steel pole in the center holds up the conical tent on top.
If the slant height of the conical tent (from the peak of the steel pole to the top of the edge of the cylindrical wall) is 45 feet, what is the total height of the steel pole?
Answer:
It is given in the question,
Diameter of Cylinder(d)= 56 m
Radius of Cylinder(r) = 56/2 m = 28 m [Hence, Radius is the half of the Diameter].
Height of Cylindrical part = 6m
Now,
C.S.A of Cylinder = 2 x pi x r x h.
=> C.S.A = 2 x 22/7 x 28 x 6
=> C.S.A = 2 x 22 x 4 x 6
=> C.S.A = 1056 m^2
Again,
Cylinder is summounted by Cone.
So,
Radius of Cone = Radius of Cylinder = 28 m
Height of Cone = Total height of tent-Height of Cylinder = (27-6) m = 21 m
Now,
We are required to find out Slant Height of Cone, For which there is a Formula,
=> l^2 = r^2+h^2
=> l^2 = 28x28 + 21x21
=> l^2 = (784+441) m^2
=> l^2 = 1225 m^2
=> l = Root 1225 m^2
=> l = 35 m.
Now,
C.S.A of Cone = pi x r x l
=> C.S.A = 22/7 x 28 x 35
=> C.S.A = 22 x 4 x 35
=> C.S.A = 3080 m^2
Now,
Total Area covered by Canvas = C.S.A of Cylinder + C.S.A of Cone
=> Total area = (1056+3080) m^2
=> Total area = 4136 m^2

At Frameworks Hardware Store's annual start-of-summer sale, every drill set in the shop gets marked down. Arianna purchased 2 drill sets during the sale: one for herself and one to give her grandpa on Father's Day. Each drill set cost $25 less than its full price. She paid a total of $86.
write an equation you can use to find f, the cost of each drill set at full price?
Assuming f to be the cost of the drill set at full price,
The equation which will represent this is
2( f- 25) = 862(f−25)=86
Solve for f to get
2f - 50 = 862f−50=86
2f = 1362f=136
f = 68f=68
The cost of the drill set at full price is $68.
