Number 8. Solve the equation for variable d. Correct answer will get brainliest.
Answers
The first step is to multiply both sides by 3
c = (2d+1)/3
3c = 3*(2d+1)/3
3c = 2d+1
Then you subtract 1 from both sides to get
3c-1 = 2d+1-1
3c-1 = 2d
2d = 3c-1
Finally divide both sides by 2 to fully isolate d
2d = 3c-1
2d/2 = (3c-1)/2
d = (3c-1)/2

Find the distance between the points t(13, 1.6)t(13, 1.6) and v(5.4, 3.7)v(5.4, 3.7).
Answers
7.88 units is the distance between points T(13, 1.6) and V(5.4, 3.7).
To find the distance between the points T(13, 1.6) and V(5.4, 3.7), we can use the distance formula:
Distance formula:
For two points [tex](x_1, y_1)[/tex]and [tex](x_2, y_2)[/tex], the distance between them is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.[/tex]
Let's plug in the coordinates of points T and V:
Distance = [tex]\sqrt{(5.4 - 13)^2 + (3.7 - 1.6)^2}[/tex]
= [tex]\sqrt{(-7.6)^2 + (2.1)^2}[/tex]
= √(57.76 + 4.41)
= √62.17
= 7.88.
So, the distance between points T(13, 1.6) and V(5.4, 3.7) is approximately 7.88 units.

What is 8 21/40 I don't understand how to do it
Answers
If you want to know it as a "improper fraction" , you can
Multiply the denominator from the front number
Whatever the denominator and front number is , you add it to the numerator
So, for this problem we first have the multiply the front number from the denominator
Like: 8 (40)
That gives us the answer of: 320
Now we have to add 320 to 21
Like: 320 + 21
That gives us the answer of:341
We keep our denominator (which is "40" )
Your improper fraction would be:
341 / 40
Good luck on your assignment and enjoy your day!
~MeIsKaitlyn:)
You can either solve this by dividing 21/40 and then adding 8 to it.
21/40 = 0.525
0.525 + 8 = 8.525
Another way is to change it into an improper fraction. This is done by multiplying the denominator (40) by the whole number (8) then adding that to the numerator (21). That number then becomes the numerator, but make to keep the denominator the same (40).
40 × 8 = 320
320 + 21 = 341
8 21/40 = 341/40
Then input 341/40 into a calculator or do long/short division.
341/40 = 8.525
Either way, the answer will be 8.525.

Answers
Part 1: 10, 15, 20, 25, 30, ... Look at the difference between the first term and the second term: it's increased by 5. Now look at the difference between all following terms and you'll notice that this pattern is repeated. Then our recursive formula would be:
[tex] a_{n}=a_{n-1}+5 [/tex]
Now a geometric sequence, on the other hand, will have a common ratio between terms. This means that the second term divided by the first term will give you the same number as the fifth term divided by the fourth term. Let's look at Part 2:
Dividing the second term by the first term, we see that the ratio is 6/2=3. Now dividing any other two terms similarly, we can see that the ratio is still 3. Then our recursive formula is:
[tex]a_n=3a_{n-1}[/tex]
Final answer:
The first sequence is arithmetic with an explicit formula of a_n = 10 + (n - 1) × 5 and recursive formula a_n = a_(n-1) + 5, a_1 = 10. The second sequence is geometric with an explicit formula of a_n = 2 × 3^(n-1) and recursive formula a_n = a_(n-1) × 3, a_1 = 2.
Explanation:
Analysis of Sequences
The first sequence: 10, 15, 20, 25, 30... increases by a constant amount of 5 which is an indication of an arithmetic sequence. The explicit formula for an arithmetic sequence is a_n = a_1 + (n - 1)d, where a_1 is the first term and d is the common difference between the terms. In this case, a_1 = 10 and d = 5. Hence, the explicit formula is a_n = 10 + (n - 1) × 5. The recursive formula for an arithmetic sequence is a_n = a_(n-1) + d, which would translate to a_n = a_(n-1) + 5 with a_1 = 10.
The second sequence: 2, 6, 18, 54, 162... multiplies by a common ratio of 3 which classifies it as a geometric sequence. The explicit formula for a geometric sequence is a_n = a_1 × r^(n-1), where a_1 is the first term and r is the common ratio. For this sequence, a_1 = 2 and r = 3, so the explicit formula is a_n = 2 × 3^(n-1). The recursive formula for a geometric sequence is a_n = a_(n-1) × r, which for this sequence is a_n = a_(n-1) × 3 with a_1 = 2.

You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.
f(x) = x^3 + 6 ----> Switch f(x) and x
x = f(x)^3 + 6 ----> Subtract 6 from both sides
x - 6 = f(x)^3 ----> Take the cube root of both sides
[tex] \sqrt[3]{x - 6} [/tex] = f(x) ----> Switch the order for formatting purposes
f(x) = [tex] \sqrt[3]{x - 6} [/tex]

You are planning a party to the local pizza arcade for your child's birthday. The cost of a birthday party is $8.95 per person, and you plan to have 12 people at the party.
Answers
The total cost would be $107.40
Last year, a baseball team paid $20 per bat and $12 per glove, spending a total of $1040. This year, the prices went up to $25 per bat and $16 per glove. The team spent $1350 to purchase the same amount of eqipment as last year. How many bats and gloves did the team purchase each year?
Answers
You can solve this question using a system of equations. Let x be the number of bats and y be the number of gloves. The first equation will contain 20x and 12y and the second equation will contain 25x and 16y. The equations will be set to the total amount of money they were given per year:
20x + 12y = 1040
25x + 16y = 1350
To solve the system, make one of the terms the same but have the opposite signs using multiplication. This will cancel one of them out. It can be any term you see is easiest. Just make sure that one of the terms is set to 0 by the end of this step.
–1.25(20x + 12y = 1040)
25x + 16y = 1350
In this case, you can multiply the first equation by –1.25 to make 20x into –25x. This will cancel out the x term. Make sure you multiply the entire first equation.
–25x + (–15y) = –1300
25x + 16y = 1350
Now, just add the two equations together.
0x + 1y = 50
y = 50
Now that you know what y is equal to, plug it into your first equation (the original) to find x. This pair will be your answer.
20x + 12y = 1040
20x + 12(50) = 1040
20x + 600 = 1040
20x = 440
x = 22
So, the pair is (22, 50). This means that the team bought 22 bats and 50 gloves.
Hope this helped you out! :-)
The baseball team purchased 22 bats and 50 gloves last year.
Explanation:To solve this problem, let's use a system of equations. Let x represent the number of bats and y represent the number of gloves purchased last year. We can set up the following equations:
20x + 12y = 1040 (equation 1) 25x + 16y = 1350 (equation 2)
We can solve this system of equations by using either the substitution method or the elimination method. Let's use the elimination method:
Multiply equation 1 by 5 and equation 2 by 4 in order to create equal coefficients for x:100x + 60y = 5200 100x + 64y = 5400 Subtract the equations to eliminate x:(100x + 64y) - (100x + 60y) = 5400 - 5200 4y = 200 y = 50
Now we can substitute the value of y back into equation 1 to solve for x:
20x + 12(50) = 1040 20x + 600 = 1040 20x = 440 x = 22
Therefore, the team purchased 22 bats and 50 gloves last year.

a square reflecting pool has an area of 183.84 square meters. What is the approximate perimeter of the reflecting pool?
Answers
The perimeter of a square reflecting pool with an area of 183.84 square meters is approximately 54.24 meters.
Explanation:The area of a square is calculated by squaring the length of one of its sides. So, to find the side length of the square reflecting pool, we need to take the square root of the area. The square root of 183.84 is approximately 13.56 meters.
Now considering that a square has four equal sides, the perimeter is calculated by multiplying the side length by 4. So, the perimeter of the pool is 13.56 multiplied by 4, which gives us approximately 54.24 meters. Therefore, the approximate perimeter of the reflecting pool is 54.24 meters.

B)coordinate plane with two intersecting lines
C)coordinate plane with two coinciding lines
D)coordinate plane with two intersecting lines
Answers
Answer: C)coordinate plane with two coinciding lines has infinitely many solution.
Step-by-step explanation:
Since, By option A) If there is a coordinate plane with two parallel lines.
Then, It has no solution ( because, we get the solution at the the intersection point of the two lines but parallel lines do not intersect each other).So, it does not have infinite many solution.
By Option B) If there are two intersecting lines then we can get only one solution. So, it does not have infinite many solution.
By Option C) If there are two coinciding lines then we can get infinite number of intersection points therefore the system must have infinite number of solution.
Note: here, Option D) is same as Option B)
Therefore Only option C) is correct.
