HELP PLEASE! 40 POINTS AND WILL MARK BRAINLIEST.
Suppose you want to find the 40th term of a sequence. Would you rather use a recursive rule or an explicit rule? Explain your reasoning.
Answer:
Explicit rule, because you can find the 40th term directly using the explicit rule. You would need to find the first 39 terms before finding the 40th terms using recursive rule.

Rashmi bought 2/3 meter of cloth and Madhu bought 2/5 meter of cloth. Who bought more cloth and how much?
Rashmi =4/15
Madhu=4/15
Rashmi=3/10
Madhu=3/10
Answer:
Reshmi bought more cloth by 4/15...
Step-by-step explanation:
1st equalize the denominator of 2/3 and 2/5
lcm of the denominators 3 and 5 is 15
2/3*5/5=10/15
2/5*3/3=6/15
Rashmi bought 10/15 m cloth
madhu bought 6/15 m cloth .
therefore, Rashmi bought more cloth
by how much more?
10/15-6/15 = 10-6/15=4/15
therefore, reshmi bought more cloth by 4/15

The bill for the repair of a car was $357. The cost for the parts was $285. The cost of labor was $32 per hour. Use an equation to find out how long it took for the mechanic to repair the car?
Answer:
2.25 hours
Step-by-step explanation:
Hope this helps! sorry was a tad bit late
It took 2 hours and 15 minutes to repair the car.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Total bill for the repair of car = $357
Let's say it took x hour to repair the car
So,
32x will be the labor cost
Now,
Labor cost + cost of parts = total bill
So,
32x + 285 = 357
32x = 72 ⇒ x = 2.25 hour
Now,
0.25 hour in minutes ⇒ 0.25 × 60 = 15 minutes.
Hence "It took 2 hours and 15 minutes to repair the car".

Order the sides of each triangle from shortest to longest
9514 1404 393
Answer:
9) AB, AC, BC or c, b, a
10) EG, (EF, FG) or f, (e, g)
Step-by-step explanation:
Sides are in the same order as their opposite angles. Generally the angle has an upper-case letter for its name, and the opposite side has the same lower-case letter for its name.
__
9) angle C is 32°, opposite side c, which is also labeled AB
angle B is 68°, opposite side b, which is also labeled AC
angle A is 80°, opposite side a, which is also labeled BC
Shortest to longest, the sides are c, b, a.
__
10) angle F is 50°, opposite side f, which is also labeled EG
The remaining two angles are both 65°, so have no smallest/largest order. Likewise their opposite sides are the same length, so have no shortest/longest order.
angles E and G are opposite sides e and g, also labeled FG and EF, which are the same length
The shortest side is f; sides e and g are longer and are the same length.
The ratio of the width to the length of a rectangle is 3 to 5.
The perimeter of the rectangle is 64 cm.
What are the width and length of the rectangle?
Step-by-step explanation:
let width= 3x and length = 5x
perimeter = 64cm
now perimeter = 2(length+width)
64= 2(3x+5x)
64 = 16x
x = 4
therefore width= 3 X 4 = 12
length = 5 X 4 = 20

Answer:

120/10=12, 120/5=24, 120/9=40/3, 120/3=40, 120/20=6, 120/7=12+1/7
2) Albert has a $16,000, six-year loan with an APR of 7.25%.
a. What is the monthly payment?
b. What is the total amount of the monthly payments?
c. What is the finance charge?
For a standard, year $16000 home/car loan 7.25% APR with payments due at the end of the month, calculate the monthly payment:
Calculate Months:
Your loan term is for years.
Months = 12 * Years
Months = 12 *
Months = 0
Now calculate monthly Annual Percentage Rate (APR):
APR = Annual APR
12
APR = 7.25
12
APR = 0.0060416666666667 <----- This is the effective interest each month.
Now calculate Annual Percentage Yield (APY):
APY = ((1+APR)12 - 1) * 100%
APY = ((1 + 0.0060416666666667)12 - 1) * 100%
APY = ((1.0060416666667)12 - 1) * 100%
APY = (1.0749582974213 - 1) * 100%
APY = 0.074958297421329 * 100%
APY = 7.5% <----- What you actually pay in interest with monthly compounding.
Calculate our monthly loan payment:
Monthly Payment = Loan Amt * APR
1 - (1/(1 + APR))n
Monthly Payment = 16000 * 0.0060416666666667
(1 - (1 /(1 + 0.0060416666666667))0
Monthly Payment = 96.666666666667
(1 - (1 / 1.0060416666667)0
Monthly Payment = 96.666666666667
1 - 0.99399461586250
Monthly Payment = 96.666666666667
1 - 1
Monthly Payment = 96.666666666667
0
Monthly Payment = 0
Now calculate the total number of payments you will make:
Total Payments = Monthly Payment * Months in the Loan
Total Payments = 0 * 0
Total Payments = $0.00
You will end up paying $0.00 - $16,000.00 = $-16,000.00 above the principal on this loan.

1/2r−3=3(4−3/2r)
Answer:
r = 3
Step-by-step explanation:
[tex]\dfrac{r}{2} - 3 = 3(4 - \dfrac{3r}{2} )[/tex]
The first step to solve for "r" is to simplify the distributive property on the RHS. To simplify the distributive property, we need to multiply the term outside the parenthesis with the terms inside the parenthesis.
[tex]\rightarrow \dfrac{r}{2} - 3 = 12 - \dfrac{9r}{2}[/tex]
Now, add 9r/2 and 3 both sides to isolate the constants and variables.
[tex]\rightarrow \dfrac{r}{2} + \dfrac{9r}{2} = 12 + 3[/tex]
Simplify both sides.
[tex]\rightarrow \dfrac{10r}{2}= 12 + 3[/tex]
[tex]\rightarrow 5r = 15[/tex]
Divide 5 both sides.
[tex]\rightarrow \boxed{r = \frac{15}{5} = 3}[/tex]

A company bought 28 desks for each
of its 17 offices. How many desks were
bought altogether?
Answer:
476
Step-by-step explanation:
THAT SHOULD BE 28*17 Wich is 476
Answer:
28 x 17 = 476
Step-by-step explanation:
It's saying it buys 28 desks for each office. Since there's 17 offices you have to add 28 17 times, so basically you multiply 28 by 17 and you get 476 which is the total number of desks bought.

A store sells paint sets each paint set costs the same amount during a sale the store reduces the price of each paint set by $1.35 Jenny sends $6.88 on 2 paint sets at the sale price. What was the price of 1 paint set before the sale?
Answer:
$4.79
Step-by-step explanation:
divide $6.88/2
add $1.35 that's it
Money reduction on a paint set during a sale = $1.35
Cost of two paint sets Jenny bought in a sale = $6.88
Given :-
Cost of every paint set is equivalent .
Then :-
Cost of each paint set during the sale :-
[tex] = \frac{6.88}{2} [/tex]
[tex] = $3.44[/tex]
The cost of each painting set during the sale was $3.44 .
Cost of each paint set before the sale :-
[tex] = 3.44 + 1.35[/tex]
[tex] =$4.79[/tex]
Therefore , the cost of each paint set before the sale was = $4.79 .
For what values of a are the following expressions true?
| a-5 | = 5-a
what values of a are the following expressions true?
Expression :-|a-5| =5-a
Answer:-Try putting values of ( a )
Greater than 5 Less than 5 Equal to 5First attempt :- Greater than 5picking random number :-
Putting a = 6 :-
[tex] |a-5| =5-a \\ |6-5| =5-6 \\ | 1| = -1 \\ 1 \cancel = ( - 1) [/tex]
so a is not equal to 6
Putting a = 8
[tex]|a-5| =5-a \\ |8 - 5| =5-8 \\ |3| = - 3 \\ 3 \cancel = - 3[/tex]
a is also not equal to 8
so above values we can find a common result that a not equal to value bigger than 5
Second attempt :- Less than 5picking random number
Putting a equal to 1
[tex]|a-5| =5-a \\|1-5| =5-1 \\ | - 4| =4 \\ 4 = 4[/tex]
a can be equal to 1
Putting a equal to -3
[tex]|a-5| =5-a \\| - 3-5| =5-( - 3) \\ | - 8| = 8\\ 8 = 8[/tex]
a can be equal to -3
So we can have a common result that a can be equal to values less than 5
Third attempt :- a equal to 5putting a equal to 5
[tex]|a-5| =5-a \\ |5 - 5| =5-5 \\ |0| =0 \\ 0 = 0[/tex]
So we can say a can be equal to 5
Result :- (a) can be equal to or less than 5The equation 2x2 − 3x + 1 = 0 is in quadratic form. true or false
