Answer:
x = -2
Step-by-step explanation:
4(x+5)=12
Distribute.
4x+20=12
Subtract 20 from both sides.
4x+20-20=12-20
4x = -8
Divide both sides by 4.
4x/4 = -8/4
x = -2
A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.

Find the shortest length of wood that can be cut into equal lengths of 3m. 8
and 12m
Answer:
24
Step-by-step explanation:
Find LCM of 3 8 and 12
(calculation attached)
lcm = 3 x 2 x 2 x 2 = 24
i hope im right!
The shortest length of the wood will be 24 meters.
The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all possible multiples for both numbers. Calculating this least common multiple for numbers is made easier by the LCM formula.
Given that the length of the wood is 3m, 8m, and 12 m. The shortest length will be calculated by taking the least common factor of the given lengths 3m, 8m, and 12 m.
The least common factor is calculated as:-
3 = 3 x 1
8 = 2 x 2 x 2
12 = 2 x 2 x 3
LCM = 3 x 2 x 2 x 2 = 24
Hence, the shortest length of the wood will be 24 meters.

can the sides of a triangle have lengths 3, 4, and 7?
Answer:
The length of the third side of a triangle must always be between (but not equal to) the sum and the difference of the other two sides. ... Therefore, the third side length must be greater than 4 and less than 8. Because 7 is greater than 4 and less than 8, it is possible for these to be the side lengths of a triangle.
Step-by-step explanation:
The sides of length 3, 4 and 7 does not form triangle.
What is a triangle?Three edges, three angles, and three vertices are the characteristics of a triangle in geometry. In geometry, it is a basic figure.
The sum of the angles of a triangle is always 180°
Given that,
Sides of a triangle are 3, 4 and 7.
Since, the one side of a triangle is greater than the difference of other two sides and less than sum of the two sides.
Implies that,
If side 3 is taken, then 3 should greater than difference of 7 and 4, also less than sum of 7 and 4.
Implies that,
7 - 4 < 3 < 7 + 4
3 < 3 < 11
Here, the condition does not satisfy. Therefore, The given lengths do not make triangle.

Find the length of CA to the nearest tenth of a foot
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{CA}[/tex] = [tex]\frac{2.6}{CA}[/tex] ( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = [tex]\frac{2.6}{tan40}[/tex] ≈ 3.1 ft ( to the nearest tenth )

What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
Melissa and Robbie are flying remote control gliders.
The altitude of Melissa's glider, h(s), in feet, is modeled by this function:
m(s) = 0.4(s³ - 11s² + 31s - 1)
Plug s = 6 seconds in the function m(s)
m(6) = 0.4(6³ - 11(6)² + 31(6) - 1)
m(6) = 0.4(216 - 396 + 186 - 1)
m(6) = 0.4(5)
m(6) = 2 feet
From the graph of Robbie:
At s = 6 seconds
Altitude = 13 feet (approximately)
Thus, Robbie reaches the greater maximum altitude in the first 6 seconds after launch option (C) Robbie's glider is correct.
