Answer:
Chemical.
Explanation:
So, before the bread was the normal color like all breads are, but then the bread was in the toaster for way to long. It started to turn black. Therefore, the change of color would be a chemical change.
Also this is the wrong subject. I'm pretty sure it's supposed to be Biology.
how to solve 9x-5-(-6x)
Answer: 3x-5
Step-by-step explanation:
9x-5(-6x)
9x-5-6x
3x-5
Answer:
15x - 5
Step-by-step explanation:
We have the equation 9x - 5 - (-6x) and are asked to solve it.
We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :
9x - 5 - (-6x)
Two negatives make a positive, therefore :
9x - 5 + 6x
Since 9x and 6x have the same variable ending, we can combine them, do as followed :
9x - 5 + 6x
9x + 6x
15x - 5

An artist spent $75 on supplies to create paintings. Each painting the artist created was sold for $25.
Which function can be used to find p, the profit when x paintings are sold?
Answer: 25*x=p
or
75/25=3
3= how many paintings the artist made
Step-by-step explanation:
If you divide 75 by 25, you get 3. Use that 3 to find the profit. Or it could be 25 times x which would get you the amount of p.
Solve for x

Answer: 18.5 equals x.

Angela painted 4 pictures in 7 days. She paints additional pictures at the rate of 1 per day. Which recursive function gives the total number of pictures she will have painted at any day in the future? How many pictures will she have painted if she paints for another 5 days after the initial week?
Answer:
The recursive function gives the total number of pictures Angela will have painted at any day in the future is:
PP(t) = t + [tex]\frac{4}{7}t[/tex]The number of pictures will she have painted if she paints for another 5 days after the initial week is:
18.86Step-by-step explanation:
To obtain the recursive function, you must take into account the next:
1. Angela paints 4 pictures in 7 days, by this, you can say Angela paints 4/7 of a picture by day.
2. Angela paints additional 1 picture by day, with this, the number of pictures painted additionally is equal to the time t (because 1 day = 1 picture, 2 days = 2 pictures and so on). With the data taken into account, we can elaborate the next function:
PP(t) = t + [tex]\frac{4}{7}t[/tex]Where:
PP: Painted pictures.t: time in days.For example, if you need to know how many pictures she painted in the first week, you can calculate replacing t by 7:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(7) = 7 + [tex]\frac{4}{7}*7[/tex]PP(7) = 7 + 4PP(7) = 11If she paints for another 5 days (I mean 12 days taking into account the initial week), we can calculate:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(12) = 12 + [tex]\frac{4}{7}*12[/tex]PP(12) = 12 + [tex]\frac{48}{7}[/tex]PP(12) = [tex]\frac{132}{7}[/tex]PP(12) = 18.86To the day 12, Angela will paint 18.86 pictures.
Answer:
The recursive function that gives the total number of pictures she will have painted at any day in the future is
next = now + 1, starting at 4 , and the total number of pictures after a week plus 5 days is 9.

You deposit $3000 into an account that pays 4.8% interest, compounded monthly. A) What is the value of the account after 5 years?B) How long will it take for the value of the account to reach $6000?
Answer:
14.4 years (about 14 years 6 months)
Step-by-step explanation:
Given data
Principal= $3000
Rate= 4.8%
A. Time= 5 years
The expression for compound interest is
A=P(1+r)^t
Substitute
A= 3000(1+0.048)^5
A= 3000(1.048)^5
A=3000*1.264
A=$3792
Hence the balance will be $3792
B. Final Amount A = $6000
The expression to find time is given ast
t= ln(A/P) / r
substitute
t= ln(6000/3000)/0.048
t= ln2/0.048
t= 0.6931/0.048
t=14.43
Hence the time is 14.4 years (about 14 years 6 months)approx

Mount McKinley, in Alaska, is about 3.848 miles high. If a mountain climber can climb 0.25 miles per day, about how long to the nearest day, would it take to climb Mount McKinley?
Answer:
About 16 days.
Step-by-step explanation:
The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.
Which expression is equivalent to

If the interest of a sum of money in 6years is 3 by 8 of the principal what is the rate of interest
Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25
