38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.
Answer:
T.A. = 16√3 units²
Step-by-step explanation:
∵ The total area = the area of the four faces
∵ The four faces are equilateral triangles with side length 4
∵ Area of the equilateral Δ = 1/4 s² √3
∴ T.A. = 4 × 1/4 × 4² × √3 = 16√3 units²
Answer:
1/6
Step-by-step explanation:
Hillary is making a blanket for her mom.
Let the total blanket = 1
Three-fourths of the blanket is green and the rest is yellow.
The fraction for the rest(yellow portion) = 1 - 3/4
The Lowest Common Denominator is 4
Hence,
4 - 3 /4 = 1/4
Two-thirds of the yellow part has her name on it.
The fraction of the blanket that will have her name on it is calculated as
2/3 of 1 /4
= 2/3 × 1/4
= 1/6
9×7=63
63÷2=31.5
31.5×4=126
7×7=49
126+49=175
175 is the answer
Answer:
45
Step-by-step explanation:
90+2x=180
2x=180-90
2x=90
x=90/2
x=45
