Answer:
1160 will be the new amount after 2 years
Step-by-step explanation:
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
Therefore 1160 is the new amount after two years.
a teacher brought to class a pack of notebooks. if her gives his students 5 notebooks to each, he will have 7 notebooks left. if he tries to give each student 7 notebooks, he will be 5 notebooks short. how many students are there in the class?
Answer:
6 students
Step-by-step explanation:
Let the number of notebooks be $x$ and the number of students be $y.$
If there are 5 notebooks per student, we have:
$x-5y=7$
Simliairly, we have 7 notebooks per person, which is:
$x-7y=-5$
Then, using system of equations, we can add multiply the first equation by $-1$ and then add.
We would have:
$-1(x-7y=-5)=-x+7y=5$
Then, adding gives us:
$2y=12$
$y=6$
There are 6 students in the class.
Let x represent the number of students that are there in the class.
The teacher her gives his students 5 notebooks each, and still has 7 notebooks left.
The number of note books = 5x + 7 (1)
The teacher her gives his students 7 notebooks each, and was 5 notebooks short.
The number of note books = 7x - 5 (2)
Therefore equating equations 1 and 2:
5x + 7 = 7x - 5
7x - 5x = 7 + 5
2x = 12
x = 6
There are 6 students in the class.

He has visited the ATM for

His balance is $2,686.00
$2,000.00 + $1,000.00 = $3,000.00 + $450.00 = $3,450.00
$3,450.00 - (($275.00 + $40.00) + (($47.00 + $92.00) + ($101.00 + $209.00)) = $2,686.00

Semi-conservative. Replication produces two helices that contain one old and one new DNA strand.
Dispersive.
Step-by-step explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

5) Function I has a greater y-intercept than function II
Step-by-step explanation:
[] They both have negative unit rates / slope (m is the slope in y = mx + b)

5(6a +1) = 7(4x + 3) w/steps
Answer:
[tex]\frac{15a- 8}{14} = x[/tex]
Step-by-step explanation:
Step 1 - Divide both sides of the equation by 7:
[tex]5(6a + 1) = 7(4x + 3)\\[/tex]
[tex]\frac{5(6a + 1)}{7} = \frac{7(4x + 3)}{7} \\\\\frac{5(6a + 1)}{7} = 4x + 3[/tex]
Step 2 - Subtract 3 from both sides to isolate the 4x:
[tex]\frac{5(6a + 1)}{7} - 3 = 4x + 3 - 3\\\frac{5(6a + 1)}{7} - 3 = 4x[/tex]
Step 3 - Expand equation:
[tex]\frac{5(6a + 1)}{7} - 3 = 4x \\\\\frac{30a + 5}{7} - 3 = 4x[/tex]
Step 4 - Translate -3 into a fraction and add it:
[tex]\frac{30a + 5)}{7} - 3 = 4x\\\frac{30a + 5 + (7 * -3)}{7} = 4x\\\frac{30a + 5 + (-21)}{7} = 4x\\[/tex]
[tex]\frac{30a - 16}{7} = 4x[/tex]
Step 5 - Divide both sides of the equation by 4:
[tex]\frac{\frac{30a - 16}{7}}{4} = \frac{4x}{4}[/tex]
Multiply the two fractions together to simplify:
[tex]\frac{30a - 16}{4 * 7} = \frac{4x}{4}[/tex]
[tex]\frac{30a - 16}{28} = x[/tex]
Step 6 - Simplify by dividing the fraction by 2:
[tex]\frac{(30a \div 2)- ( 16 \div 2)}{28 \div 2} = x[/tex]
[tex]\frac{15a- 8}{14} = x[/tex]

Given the function f(x)=-x^2+6x+17 determine the average rate of change of the function over the interval −3≤x≤7.
Answer:
2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 3, 7 ] , then
f(b) = f(7 ) = - 7² + 6(7) + 17 = - 49 + 42 + 17 = 10
f(a) = f(- 3) = - (- 3)² + 6(- 3) + 17 = - 9 - 18 + 17 = - 10
average rate of change = [tex]\frac{10-(-10)}{7-(-3)}[/tex] = [tex]\frac{10+10}{7+3}[/tex] = [tex]\frac{20}{10}[/tex] = 2

help ? lol..
i’m stuck on this
Answer:
24 ?
Step-by-step explanation:
I may be wrong but I believe the answer is 24 since she lost half of her CDs a week later. The number 6 is not important to the word problem as the only information we need in the amount she has left and the amount she lost. I may be wrong so please check the work again?
Answer:
18 CDs
Step-by-step explanation:
To find how many she started with, It says she lost half, meaning she had must have had 24. Because 12 is half of 12. If she lost half of 24, she would have 12 left. Before she bought 24, she had 6 less, because she bought meaning plus, 6. But to get the beggining, you do the oppisite, which is minus 6. So, 24-6 to get 18.
To make sure we are correct plug in 18. She starts out with 18. She buys, 6. So plus 6. 18+6 to get 24. But she then a week later lost half, leaving her with 12 CDs. By seeing this, we can tell, she did in fact, have 18 CDs to start out.
P.S wow she must really be dum b to lose an entire an entire 12 CDs in a couple hours.
