The value of x in the triangle is 9, the volume of the cylinder is 1272.3 yd³ and the volume of the sphere is 268.1 mi³.
What is the numerical value of x in the triangle?To solve for the value of x in the triangle, we use ratio:
[tex]\frac{20}{20 + 16}=\frac{45}{45 + 3x + 9}[/tex]
Simplify and solve for x:
20/36 = 45/(3x + 54 )
Cross mulltiply:
20( 3x + 54 ) = 36 × 45
60x + 1080 = 1620
60x = 1620 - 1080
60x = 540
x = 540/60
x = 9
Therefore, the value of x is 9.
Option A) 9 is the correct answer.

What is the surface area (S.A) of the circle shown below in terms of π
r = 4 inches.
h = 6 inches.
Answer:
64π
Step-by-step explanation:
To calculate the surface area (S.A) of the circle with a radius (r) of 4 inches and a height (h) of 6 inches, we need to consider both the curved surface area (lateral surface area) and the area of the circular base.
The curved surface area, also known as the lateral surface area, is calculated using the formula:
L.A = 2πrh
Substituting the given values, we have:
L.A = 2π(4)(6)
L.A = 48π square inches
The area of the circular base is calculated using the formula:
A = πr^2
Substituting the given radius, we have:
A = π(4^2)
A = 16π square inches
To find the total surface area (S.A), we need to sum the lateral surface area (L.A) and the area of the circular base (A):
S.A = L.A + A
S.A = 48π + 16π
S.A = 64π square inches
Therefore, the surface area (S.A) of the given circle is 64π square inches.

The revised Doubtful Debts Provision should be, $4,555.
Now, Using a net debtors value of $91,100 and a provision rate of 5%, use the calculation to get the adjusted Provision for Doubtful Debts (PDD):
Net Debts x Provision Rate equals Adjusted PDD.
The computation would then be:
= $91,100 x 0.05
= $4,555 is the adjusted PDD.
Because of the additional $550 in bad debt and the revised net debtors value of $91,100, the Provision for Doubtful Debts must be raised by ,

The older snail has a shell with a volume of 10 cubic centimeters. Estimate the height of the older snail’s shell. Round your answer to the nearest tenth.
can someone pls answer this asap and show ur work
The estimated height of the older snail's shell is approximately 13 centimeters.
To estimate the height of the older snail's shell, we can use the concept of proportional relationships between the heights and volumes of the snail shells.
Let's denote the height of the older snail's shell as "h" (in centimeters). We can set up a proportion based on the relationship between the heights and volumes of the snail shells:
(height of younger snail) / (volume of younger snail) = (height of older snail) / (volume of older snail)
Substituting the given values:
3.9 / 3 = h / 10
To solve for "h," we can cross-multiply and then divide:
3 * h = 3.9 * 10
3h = 39
h = 39 / 3
h ≈ 13
The estimated height of the older snail's shell is approximately 13 centimeters.

How many tacos must Derrick buy for each pricing option to be the cheapest?
Answer:
Therefore, if Derrick wants to spend a maximum of $50 and he intends to buy a maximum of 8 tacos, then the general admission option is the cheapest. If he intends to buy 9 or more tacos, then the VIP option is the cheapest.
Step-by-step explanation:
To determine how many tacos Derrick must buy for each pricing option to be the cheapest, we can set up separate equations for each pricing option based on the total cost. Let's assume Derrick wants to spend a maximum of $50 on admission and tacos.
For the general admission option:
Total cost = 15 + 4x, where x is the number of tacos
We want to find the value of x that makes the total cost the same or less than $50:
15 + 4x ≤ 50
4x ≤ 35
x ≤ 8.75
For the VIP option:
Total cost = 36 + 1.5x, where x is the number of tacos
We want to find the value of x that makes the total cost the same or less than $50:
36 + 1.5x ≤ 50
1.5x ≤ 14
x ≤ 9.33

An integer is a whole number that can be positive, negative, or zero, without any fractional or decimal parts.
The given expressions for three consecutive integers are:
x(x + 1)(x + 2)Give that twice the first number is 20 more than the second:
[tex]2x = (x + 1) + 20[/tex]
Solve this equation for x:
[tex]\begin{aligned}2x &= (x + 1) + 20\\2x&=x+1+20\\2x&=x+21\\2x-x&=x+21-x\\x&=21\end{aligned}[/tex]
The expression for the largest integer is (x + 2).
Therefore, to find the largest number, substitute the found value of x into this expression:
[tex]\begin{aligned}\sf Largest\;number&=(x+2)\\&=21+2\\&=23\end{aligned}[/tex]
Therefore, the largest number is 23.

The elements in the range that correspond to the elements 0 and 3 are y = 2 and y = 4 and the equations are solved.
Given data ,
To find the elements in the range that correspond to the elements 0 and 3 of the domain, we need to solve the equation 3y - 2x = 6 for the corresponding values of y when x = 0 and x = 3.
When x = 0:
Substituting x = 0 into the equation 3y - 2x = 6, we get:
3y - 2(0) = 6
3y = 6
y = 2
So, when x = 0, the corresponding value of y is 2.
When x = 3:
Substituting x = 3 into the equation 3y - 2x = 6, we get:
3y - 2(3) = 6
3y - 6 = 6
3y = 12
y = 4
So, when x = 3, the corresponding value of y is 4.
Hence , the elements in the range that correspond to the elements 0 and 3 of the domain are y = 2 and y = 4, respectively.

The numeric values for this problem are given as follows:
g(-1) = -2.g(2) = 0.g(3) = 0.5.How to obtain the numeric values of the function?The function in this problem is a piecewise function, meaning that it has different definitions based on the input x of the function.
For x between -2 and 2, the function is defined as follows:
g(x) = -(x - 1)² + 2.
Hence the numeric value at x = -1 is given as follows:
g(-1) = -(-1 - 1)² + 2 = -4 + 2 = -2.
For x at x = 2 and greater, the function is given as follows:
g(x) = 0.5x - 1.
Hence the numeric values at x = 2 and x = 3 are given as follows:

A boy walks 1260m on a bearing of 120°. How far south is he from his starting point
The boy is 630 meters south from his starting point.
To determine how far south the boy is from his starting pointWe must take into account the southward component of his shift.
We can imagine a right-angled triangle where the hypotenuse represents the boy's total displacement of 1260 meters, the angle between the hypotenuse and the south direction is 120°, and the side next to the angle represents the southward displacement given that the boy walks 1260 meters on a bearing of 120°.
We can use trigonometric functions to calculate the displacement to the south. Since the adjacent side and hypotenuse of a right triangle are connected in this instance, we will use the cosine function.
cos(120°) = adjacent / hypotenuse
cos(120°) = adjacent / 1260
Solving for the adjacent side (southward displacement):
adjacent = cos(120°) * 1260
adjacent = (-0.5) * 1260
adjacent = -630
The negative sign indicates that the southward displacement is in the opposite direction or "south" relative to the starting point.
Therefore, the boy is 630 meters south from his starting point.

Answer: Therefore, the correct factorization by grouping is (a - 2)(6a - 5).
Step-by-step explanation:
To factor 6a² - 12a - 5a + 10 by grouping, we can group the terms in pairs:
6a² - 12a - 5a + 10
Taking common factors from the first two terms and the last two terms separately:
6a(a - 2) - 5(a - 2)
Now, we can see that (a - 2) is common in both terms, so we can factor it out:
(a - 2)(6a - 5)
Hello!
6a² - 12a - 5a + 10

In 2040, the son's age can be written as [tex]\frac{x}{3}[/tex], where x equals the age of his father. In 2050, the son's age can be written as [tex]\frac{x-10}{2}[/tex] (as ten years is added between 2040 and 2050). When equated to each other--> [tex]\frac{x-10}{2}[/tex] = [tex]\frac{x}{3}[/tex], we can first simplify by multiplying both sides to reach the least common denomination 6, giving us 3(x-10)=2x --->3x-30=2x--->x=30 is the dad's age. The son's age in 2040, 30/3, is equal to 10 years, meaning he was born in the year 2030 (a).
