Which of the following is the best approximation of the volume of the cylinder below?
Answers
Answer:
B
Step-by-step explanation:
[tex]v = \pi {r}^{2} h \\ = 8 \\ v = \pi {8}^{2} \times 3 = 3.14 \times 64 \times 3 = 602.88 = 602.9[/tex]
The volume of the cylinder is 2411.5 cm³ in the given figure. which is the correct answer would be an option (A).
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
As per the given figure,
The radius of a cylinder is 16 cm and the height of the cylinder is 3 cm.
The volume of a cylinder = πr²h
The volume of a cylinder = π(16)² × 3
The volume of a cylinder = 3.14(256) × 3
The volume of a cylinder = 2411.5 cm³
Thus, the volume of the cylinder is 2411.5 cm³ in the given figure.

The type of triangle is an obtuse triangle.
What are obtuse triangles?A triangle is a 3-sided polygon.Every triangle has three sides and three angles, some of which may be the same. When the angles are thesame, the triangle is called an equilateral triangle.
An obtuse triangle is a type of triangle in which one of it's angles is more than 90°.
An acute triangle is a type of triangle in which none of it's angles is UpTo 90°
Also a right triangle is a type of triangle in which one of the angles is exactly 90°.
Therefore since one of the angles is 110 and it is greater than 90°, the angle is an obtuse triangle.

Answer:
x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)
Step-by-step explanation:
3(5-x) = 7x - 2
3 * 5 - 3* x = 7x - 2 (brackets means multiply)
15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

Explanation:
"Without replacement" means the card selected is not put back, and we do not put a copy of that card into the deck.
We have 5 yellow cards out of 5+9+1 = 15 cards total. The probability of picking yellow is 5/15 = 1/3. Let A = 1/3.
After picking that yellow card, we have 5-1 = 4 yellow left out of 15-1 = 14 total. The probability of picking another yellow card, after the first one is not replaced, is 4/14 which reduces to 2/7. Let B = 2/7.
Multiply the values of A and B
A*B = (1/3)*(2/7) = (1*2)/(3*7) = 2/21
The probability of picking two yellow cards, without replacement, is 2/21

The point (0, 5) is the midpoint between (-18, -10) and what other point?
A. (18, 20)
B. (18, 15)
C. (20, 18)
D. (20, 20)
Answers
Answer:
The coordinates of the other point are:
(x₂, y₂) = (18, 20)
Hence, option A is correct.
Step-by-step explanation:
Given
The midpoint (x, y) = (0, 5)The first point (x₁, y₁) = (-18, -10)To determine
The second point (x₂, y₂) = ?Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)
[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
Here:
(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)
substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula
[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]
equating
[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]
[tex]x_2-18=0[/tex]
Add 18 to both sides
[tex]x_2-18+18=0+18[/tex]
[tex]x_2=18[/tex]
also
[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]
[tex]10=y_2+\left(-10\right)[/tex]
[tex]10=y_2-10[/tex]
[tex]10+10=y_2[/tex]
[tex]10+10=y_2[/tex]
[tex]y_2=20[/tex]
Therefore, the coordinates of the other point are:
(x₂, y₂) = (18, 20)
Hence, option A is correct.
Answer:
(x₂, y₂) = (18, 20)

≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is
A = [tex]\frac{1}{2}[/tex] × XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

the total of three consecutive numbers is 210. what are the numbers. show all work
Answers
Let n = the first of three consecutive numbers.
Let n + 1 = the second consecutive number, and ...
Let n + 2 = the third consecutive number.
Since we're given that: "the sum of three consecutive numbers is 210," then we can now translate this statement mathematically into the following equation to be solved for the unknown number n:
n + (n + 1) + (n + 2) = 210
n + n + 1 + n + 2 = 210
Collecting like-terms on the left, we get:
3n + 3 = 210
3n + 3 - 3 = 210 - 3
3n + 0 = 207
3n = 207
(3n)/3 = 207/3
(3/3)n = 207/3
(1)n = 69
n = 69
Therefore, ,...
n + 1 = 69 + 1 = 70 and
n + 2 = 69 + 2 = 71
CHECK:
n + (n + 1) + (n + 2) = 210
69 + (70) + (71) = 210
69 + 70 + 71 = 210
210 = 210
Therefore, the three consecutive numbers whose sum is 210 are indeed 69, 70, and 71, and 71 is obviously the largest of these three numbers

Answers
Answer : 14hours
Step-by-step explanation:
If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more

Amount earned per hour = $9
The expression to find the number of x hours to buy the camera.
25 + 9x = 150
9x = 150 - 25
9x = 125
x = 13.89
x = 14
