Answer:
d. w=13.34
Step-by-step explanation:
The value of w is 13.34 for the given equation. The correct answer is option D.
What is the solution to the equation?A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The equation is given as follows:
3(−5.8 + w) = 22.62
First, we distribute the 3 on the left side of the equation:
-17.4 + 3w = 22.62
Next, we isolate the variable by adding 17.4 to both sides of the equation:
-17.4 + 3w + 17.4 = 22.62 + 17.4
3w = 40.02
Finally, we solve for w by dividing both sides of the equation by 3:
w = 13.34
Therefore, the value of w is 13.34, so the answer is option D.

61% of 407 estimates using a rate per 100
The 61% of 407 estimates 248. 27
What is percentage?
Percentage can be defined as the ratio of a number to 100
Example;
The percentage of 55 is expressed as;
= 55/ 100
From the information given, we have to determine 61% of 407
This is expressed as;
= 61/ 100 × 407
= 0. 61 × 407
= 248. 27

It's not possible to build a triangle with side lengths of 3,3,and 9.
How to illustrate the information?It should be noted that to compute a triangle, the addition of the shortest sides must be longer than the longest side.
In this case, 3 + 3 = 6
But the longest side is 9 and it's longer than 6.
Therefore, it's not possible to build a triangle with side lengths of 3,3,and 9.

A sole proprietorship that began business on May 1, 2021, incurred $7,500 of start-up expenses. If the business elects to report the maximum amount of start-up costs as a current expense, what is the amortization amount reported as an "other expense" on Schedule C (Form 1040) for the first year of business?
$0
$111
$167
$333
Based on the start-up expenses to the sole proprietorship, the amortization amount reported as an "other expense" on Schedule C (Form 1040) for the first year of business will be $111.
What is the amortization amount?Before the amortization amount can be calculated, a deduction of $5,000 should be made because the start-up costs were less than $50,000.
The amount to be amortized is therefore:
= 7,500 - 5,000
= $2,500
The amount to be amortized will be amortized over 15 years. As the business started on May 1, 2021, there are only 8 months left in the year.
The amortization amount is:
= (2,500 x 8 months) / ( 15 x 12 months a year)
= $111

There are 63 students going on the trip, and you want to divide them up between 15 chaperones with 4 or 5 students in each group. How many groups will have 4 students, and how many will have 5?
There are 12 groups with 4 students and 3 groups with 5 students
How many groups will have 4 students, and how many will have 5?Represent the students as follows:
Group with 4 students = x
Group with 5 students = y
So, we have the following system of equations
4x + 5y = 63
x + y = 15
Make x the subject in x + y = 15
x = 15 - y
Substitute x = 15 - y in 4x + 5y = 63
4(15 - y) + 5y = 63
Expand
60 - 4y + 5y = 63
Evaluate
y = 3
Substitute y = 3 in x = 15 - y
x = 15 - 3
This gives
x = 12
Hence, there are 12 groups with 4 students and 3 groups with 5 students

Given that f(x)=2x^2-4x+5 determine if the graph is a maximum or minimum
The graph of f(x) = 2x^2 - 4x + 5 is a minimum
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine if the graph is a maximum or minimum?The equation of the function is given as
f(x) = 2x^2 - 4x + 5
The above equation is a quadratic equation.
A quadratic equation is represented as:
f(x) = ax^2 + bx + c
By comparison, we have
a = 2
b =-4
c = 5
If the value of a is positive, the graph is a maximum.
Since the value of a is 2, then it means that the graph is a minimum
Hence, the graph of f(x) = 2x^2 - 4x + 5 is a minimum

The volume of the cylinder and cone combined is (8/3)•π•r³ How can the volumes of the solid figures be calculated?The radius of cylinder = r
Height of the cylinder = 2•r
Radius of cone = r
Height of the cone = 2•r
Volume of the cylinder, Vc = π•r²•(2•r) = 2•π•r³
Volume of the cone, Vco == (1/3)•π•r²•(2•r)
Which gives; Vco == (2/3)•π•r³
