Answer:
Let x = son's age
Let 38-x = Mr. Bellini's age (since the sum of their ages must be equal to 38)
Set up the equation using the second statement:
(38 - x) - 4 = 5(x - 4)
Solving,
34 - x = 5x - 20
34 + 20 = 6x
54 = 6x
x = 9 years old (son's age)
38-x = 29 years old (Bellini's age)
Dwayne bought 12 yards of wrapping paper.
How many inches of wrapping paper did he buy? Helppp
Answer:
432 inchesStep-by-step explanation:
Given:
Dwayne = 12 yardsConversion: 1 yard = 3 feet = 36 inches
Use the unitary method and solve:
[tex]\implies \text{1 yard = 3 feet = 36 inches}[/tex][tex]\implies 1 \times 12 \ \text{yard} = 3 \times 12 \ \text{feet} = 36 \times 12 \ \text{inches}[/tex][tex]\implies 12 \ \text{yards} = 36 \ \text{feet} = 432 \ \text{inches}[/tex]Thus, Dwayne bought 432 inches of wrapping paper.
A ring-shaped region is shown below.
Its inner diameter is 14 yd., and its outer diameter is 20 yd.
Answer:
160.14yd²
Step-by-step explanation:
first we find both of their areas then we subtract the small one f4om the big one
A=πr²
step 1 find area of large circle
A=3.14×(10²)
A=3.14×100
A=314
step 2 find are of small circle
A=3.14×(7²)
A=3.14×49
A=153.86
step 3 subtract small area from big area
314-153.86=160.14

What is the surface area of the square pyramid?
Enter your answer in the box.
in²
Square pyramid net consisting of a square and four triangles. The square has length and width of eight inches. A triangle has a base of eight inches and a height of eleven inches.
Answer:
240 in²
Step-by-step explanation:
The surface area of the pyramid is the sum of the areas of the parts of the composite figure comprising the net. That is, it is the sum of the areas of four triangles and a square.
__
FaceThe area of a triangle is ...
A = 1/2bh
For the given triangles, this is ...
A = 1/2(8 in)(11 in) = 44 in²
__
BaseThe area of the square base is ...
A = s²
For the given dimensions, this is ...
A = (8 in)² = 64 in²
__
Total Surface AreaThe sum of the areas of the four faces and the base is ...
total area = 4(44 in²) +64 in² = 240 in²
The surface area of the square pyramid is 240 in².
