Nancy and bill collect coins. Nancy has x coins. Bill has 6 coins fewer than times the number of coins nancy has. Write and simplify an expression for the total number of coins nancy and bill have
Answer:
Total number of coins Nancy and bill have = 6x - 5
Step-by-step explanation:
Nancy and bill collect coins. Nancy has x coins. Bill has 5 coins fewer than five times the number of coins Nancy has. Write and simplify an expression for the total number of coins Nancy and bill have . Simplify your answer .
Let
Number of Nancy's coins = x
Number of Bill's coins = 5x - 5
Total number of coins Nancy and bill have = Number of Nancy's coins + Number of Bill's coins
= x + (5x - 5)
= x + 5x - 5
= 6x - 5
Total number of coins Nancy and bill have = 6x - 5
PLA ANSWER I DONT KNOW THIS
Answer:
x=45
Step-by-step explanation:
I can give you two solutions
First solution:
In [tex]\triangle FBA[/tex] we know that
[tex]\angle BFA + \angle FAB + \angle ABF=180\\\\90+x+\angle ABF =180\\\\\angle ABF =90-x[/tex]
same case for [tex]\angle EBC[/tex] in [tex]\triangle ECB[/tex]
so we have that
[tex]\angle ABC = \angle ABF + \angle FBE +\angle EBC\\\\\angle ABC = 90-x+45+90-x\\\\\angle ABC = 180+45-2x[/tex]
we leave it like that because it's convenient
Now by properties of parallelograms we know that opposite sides add up to 180
[tex]\angle FAB + \angle ABC = 180\\\\x+180+45-2x=180\\\\x+45-2x=0\\\\45-x=0\\\\x=45[/tex]
so one angle is 45 and the other one is 135
Solution 2
if we look at DEBF we can say that it's a cyclic quadrilateral
because opposite sides add up to 180
in our case
[tex]\angle DFB = 180 -\angle BFA = 180-90 = 90\\\\\angle DEB = 90\\\\\Rightarrow \angle DFB + \angle DEB = 180\\\\[/tex]
so for the other to angles is also true
[tex]\angle FDE + \angle EBF = 180\\\\\angle FDE +45 = 180\\\\\angle FDE = 135[/tex]
so that's the measure of one angle of the parallelogram
the other angle x is
[tex]\angle EDF + \angle FAB = 180\\\\135+x=180\\\\x=45[/tex]

Which rectangular equation represents the parametric equations x = 2sec(t) + 1 and y = 6tan(t)?
Answer:
A.)
Step-by-step explanation:
literally guessed but was right lol
Option first is correct.
What is rectangular equation?A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on regular cartesian plane.
According to the given question
We have
x = 2sec(t) + 1 and y = 6tan(t)
Now the above expressions can be written as :
x -1 = 2sec(t)
⇒ [tex]sec(t)\frac{x-1}{2}[/tex]
similarly,
[tex]\frac{y}{6} = tan(t)[/tex]
From trigonometric identities we know that
[tex]1 + tan^{2} \ t = sec^{2} \ t[/tex]
Substitute the value of tant and sect in the above identity
[tex]1 + (\frac{y}{6} )^{2} =(\frac{x-1}{2}) ^{2}[/tex]
⇒[tex]\frac{(x-1)^{2} }{4} -\frac{y^{2} }{36} =1[/tex], this is the required rectangular equation.
Hence, option first is correct.

Which orchard would be cheaper to visit if the class has 12 students?
Orchard A) admission costs $9 per person and 3 chaperones are required.
Orchard B) the cost is $10 per person, but only 1 chaperone is required.
Answer: orchard B
Step-by-step explanation: (orchard A) if you were to only bring the 12 students, the cost would be $108. But since it requires 3 chaperones you’d add 3 to the already 12 students making the full cost $135.
(Orchard B) if you were take only the 12 kids to the orchard it would cost you $120 but because it requires ONLY 1 chaperone, the final cost would be $130. allowing it to be $5 dollars less than what Orchard A would cost.

A sequence is recursively defined by f(1)=3,f(n)=2* f(n-1) for n >=2. Write the equation for the nth term
Given:
[tex]f(1)=3,f(n)=2\times f(n-1)[/tex] ...(i)
For [tex]n\geq 2[/tex].
To find:
The nth term for the given recursive formula.
Solution:
The given recursive formula is of the form of
[tex]f(n)=r\times f(n-1)[/tex] ...(ii)
It is the recursive formula of a GP, where r is common ratio.
On comparing (i) and (ii), we get
[tex]r=2[/tex]
Now,
First term: [tex]a=f(1)=3[/tex]
Common difference: [tex]r=2[/tex]
nth term of a GP is
[tex]f(n)=ar^{n-1}[/tex]
Putting a=3 and r=2, we get
[tex]f(n)=3(2)^{n-1}[/tex]
Therefore, the equation for the nth term is [tex]f(n)=3(2)^{n-1}[/tex].

5. A train travels two different routes: the North Route and the South Route. • On Monday, the train traveled the North Route 8 times and the South Route 10 times, traveling a total of 410 miles. • On Tuesday, the train traveled the North Route 15 times and the South Route 11 times, traveling a total of 575 miles. How long is each route?
Answer:
North Route is 20 miles, and South Route is 25 miles.
Step-by-step explanation:
Let the length of the North route be represented by x and that of the South route be represented by y.
On Monday,
8x + 10y = 410
On Tuesday,
15x + 11y = 575
So that,
8x + 10y = 410 .............. 1
15x + 11y = 575 ......... 2
Using substitution method, from equation 1;
x = [tex]\frac{410 - 10y}{8}[/tex] ................. 3
Substitute the expression for x into equation 2,
15([tex]\frac{410 - 10y}{8}[/tex]) + 11y = 575
multiply through by 8,
6150 - 150y + 88y = 4600
6150 - 62y = 4600
6150 - 4600 = 62y
1550 = 62y
divide through by 62 to have,
y = 25
Substitute the value of y in equation 3
x = [tex]\frac{410 - 10y}{8}[/tex]
= [tex]\frac{410 - 10(25)}{8}[/tex]
= 20
x = 20
Thus, North Route is 20 miles, and South Route is 25 miles.

The sum of interior angles of a regular polygon is 1080.Find the size of each exterior angle
Answer:
45
Step-by-step explanation:
Calculation to Find the size of each exterior angle
First step is to calculate the sum of interior angles of a polygon using this formula
Sum of interior angles of a polygon =S=(n-2)*180
Let plug in the formula
Sum of interior angles of a polygon=1080=(n-2)*180
Cross multiply
1080/180=n-2
6=n-2
Add 2 to both sides
6+2=n-2+2
n=8
Now let Find the size of each exterior angle using this formula
Size of each exterior angle=360/n
Where,
n represent numbers of sides of the polygon
Let plug in the formula
Size of each exterior angle=360/8
Size of each exterior angle=45
Therefore the size of each exterior angle will be 45

a car dealer so 32 cars their first month The next month they sell 54 cars What is the percentage of change in the number of sold cars
Answer:
68.75%
Step-by-step explanation:
First you do 54 - 32 to get 22.
Then you divide 22 by 32 to get the decimal 0.6875
Finally, you multiply 0.6875 by 100 to get 68.75% :D
Answer:
68.73% more cars were sold
Step-by-step explanation:
from 32 cars that represented 100% went to 54 so is a diference of 54-32=22
Now what percentage of 32 is 22?
32 is 100%
22 is x%
x=(22*100)/32=2200/32=68.73%
So if a video that is 15:34 how long is it when 2 times speed
tip: times 15 min. buy 60 then divdie all of the sec. by 2
Answer:
7:47
Step-by-step explanation:
Here are two ways of solving this:
The video will be half the time of 15:34, so you need to divide the time 15:34 by 2.
Method 1)
Use the tip. The video is 15 minutes and 34 seconds long.
Convert minutes to seconds: 15 * 60 = 900
Add 34 seconds to the 15 minutes: 900 seconds + 34 seconds = 934 seconds
The video is 934 seconds long.
Divide the total seconds by 2: 934/2 = 467
467 seconds = 420 seconds + 47 seconds = 7 minutes and 47 seconds
Answer: 7:47
Method 2)
Divide the minutes by 2 and divide the seconds by 2.
15 minutes and 34 seconds.
Divide minutes by 2: 15/2 = 7.5
Divide seconds by 2: 34/2 = 17
Now we need to add 7.5 minutes and 34 seconds.
0.5 minutes is half a minute, so it's 30 seconds.
7.5 minutes + 17 seconds =
= 7 minutes + 0.5 minute + 17 seconds
= 7 minutes + 30 seconds + 17 seconds
= 7 minutes + 47 seconds
= 7:47
