Step-by-step explanation:
A student bought 11 pencils and a pad of paper.
The pencils each cost the same amount.
The pad of paper costs $4.99.
The student spent a total of $18.74, not including tax
Answer:
Each pencil costs $1.25
Step-by-step explanation:
$18.74 - 4.99=13.75
13.75/11=$1.25
You have to take the total amount and subtract how much the paper pad costs then you get 13.75 and that is how much the student paid for all 11 pencils so you divide it by 11 and you get $1.25

The remainder after diving x^4+3x^3-8x^2+5x-9 by x+5 is ____.
Use the polynomial remainder theorem. It says that a polynomial [tex]f(x)[/tex] has remainder [tex]f(c)[/tex] upon division by [tex]x-c[/tex].
Here we have
[tex]f(x)=x^4+3x^3-8x^2+5x-9[/tex]

Krista drove 48 miles per hour for 8 hours. How far did krista drive
Answer:
She drove 384 miles, because 48 x 8 = 384! :)
Step-by-step explanation:
The distance driven by krista is 384 miles.
How to find the distance?If the object is going linearly, and at constant speed, then the speed of that object is given by the distance it traveled to the time it took to travel that distance.
If the object traveled D distance in T units time, then that object's speed is
[tex]Speed = S = \dfrac{\: Distance \: traveled}{\: Time \: taken} = \dfrac{D}{T} \: \rm unit \: length/unit \: time[/tex]
Given;
speed = 48 miles per hour
time = 8 hours
Speed= distance/time
distance= speed x time
= 48 x 8
= 384 miles
Krista drove 384 miles of distance in 8 hours.

Answer:

-3x + 8y = -5
6x + 2y = -8
Set the equations to a common variable.
-3x + 8y = -5 → 8y = 3x - 5 → y = 3/8x - 5/8
6x + 2y = -8 → 2y = -6x - 8 → y = -3x - 4
Set the equations equal to each other.
3/8x - 5/8 = -3x - 4
Combine like terms.
3x + 3/8x = -4 + 5/8
3.375x = -3.375
Divide by 3.375
x = -1
Plug x back in to find y.
-3x + 8y = -5
-3(-1) + 8y = -5
3 + 8y = -5
8y = -8
y = -1
answer: (-1, -1)
2.
3x + 2y = -16
-3x - 8y = 46
Set the equations to a common variable.
3x + 2y = -16 → 2y = -3x - 16 → y = -3/2x - 8
-3x - 8y = 46 → -8y = 3x + 46 → y = -3/8x - 23/4
Set the equations equal to each other.
-3/2x - 8 = -3/8x - 23/4
Combine like terms.
-9/8x = 9/4

Divide by -1.125
x = -2
Plug x back in to find y.

Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly. Which rule generates a sequence of the monthly amounts in your college book fund? answer
Answer:
A= ₱1000 + t( ₱250) ------where t is the time in months
Step-by-step explanation:
The principal amount ,P, is given as : ₱1000----- P=₱1000 ------equation (i)
Additional amounts to be added by grandmother = ₱200 monthly
Amount expected to add monthly = ₱50
Additional amounts in total added monthly = ₱200 + ₱50=₱250
Monthly amounts ,A, in the fund after the first month, t =1 month will be:
A=P + ₱250= ₱1000 + 1( ₱250) ------where t= 1, amount at end of month 1
A=P +₱250= ₱1000 + 2( ₱250)--------where t=2, amount at end of month 2
A=P +₱250= ₱1000 + 3( ₱250)---------where t=3, amount at end of month 3
A=P +₱250= ₱1000 + 4( ₱250)--------where t=4, amount at end of month 4
From the breakdown above of 4 months, the general equation of monthly amounts will be;
A= ₱1000 + t( ₱250) ------where t is the time in months
A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t) and this can be determined by forming the linear equation with the help of the given data.
Given :
Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly.The following steps can be used to determine a sequence of the monthly amounts in your college book fund:
Step 1 - Given that the principal amount is ₱1000 which is given by the grandmother.
Step 2 - Additional amount is given by grandmother is ₱200 and each month ₱50 is added. So, the total additional amount each month is:
= 200 + 50
= ₱250
Step 3 - Let 't' be the number of months. So, the linear equation becomes:
A = 1000 + 250(t)
where A is the total amount and t is the time in months.
A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t)

b. How many donors did not have type O blood? Round to the nearest whole number if necessary ____
c. Which blood type has less than 10 donors?
blood type percent
O 45
A 40
B 11
AB. 4
Answer:
a. 16
b. 80
c. Blood type AB
Step-by-step explanation:
Given:
O = 45%
A = 40%
B = 11%
AB = 4%
Total number of donors = 145
a. No. of donors that had type B blood = [tex] \frac{11}{100}*145 = \frac{1,595}{100} = 15.95 [/tex]
Type B blood donors ≈ 16
b. No. of blood donors without blood type O = [tex] \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75 [/tex]
Those without blood type O ≈ 80
c. Find the number of people that had type AB:
Type AB = [tex] \frac{4}{100}*145 = 5.8 [/tex] ≈ 6. This is less than 10 donors.
Therefore, blood type AB had less than 10 donors.
