The town of Euclid started a voluntary recycling program. The first year it was utilized by 1500 residents. Every year afterward, the number of new users was 120% of the new users the year before. After 6 years, how many people total were using the recycling program?
Answer:
170,070 residents
Step-by-step explanation:
Original population = 1500 residents
Total population after 6 years is calculated using the formula
A = P(1+r)^t
r is the rate = 120% = 1.2
t is the time = 6 years
P is the original population
A = 1500(1+1.2)^6
A = 1500(2.2)^6
A = 1500(113.379904)
A = 170,069.856
Hence the total people using the recycling program after 6 years is approximately 170,070 residents

B: n = 5/16
C: n = 3 1/5
D: n = 50
Answer:
[tex]\huge\boxed{\sf n = 5}[/tex]
Step-by-step explanation:
[tex]\sf \frac{4}{n} = \frac{4}{5} \\\\Cross \ Multiplying \\\\n * 4 = 4*5\\\\Divide \ both \ sides \ by \ 4 \\\\\frac{n*4}{4} = \frac{4*5}{4} \\\\n = 5 \\\\\rule[225]{225}{2}[/tex]
Hope this helped!
~AH1807Answer:
n = 5
Step-by-step explanation:
[tex] \frac{4}{n} = \frac{4}{5} [/tex]
Dividing 4 on both the sides gives ,
[tex] = > \frac{4}{n} \div 4 = \frac{4}{5} \div 4[/tex]
[tex] = > \frac{4}{n} \times \frac{1}{4} = \frac{4}{5} \times \frac{1}{4} [/tex]
Cancelling 4 from numerator and denominator from both the sides ,
[tex] = > \frac{1}{n} = \frac{1}{5} [/tex]
Cross-multiplying the denominators of both sides,
[tex] = > n = 5[/tex]
You are Christmas shopping and your bill at the register is $130. You have two coupons, but you are only allowed to use one. Coupon 1 is for 10% off. Coupon 2 is for $10 off. Answer the following question 7a-7b-7c
Answer:
the answer is 10 percent off because that is 13 dollars
Step-by-step explanation:
if you do 130 times 10 it is 1300, then divide by 100 it equals 13 dollars off. if you did the other coupon it would only be 10 dollars off
Alexandra has 4 bags of beads. Some of the bags contain 3 purple beads and the rest contain 6 indigo beads. If Alexandra has 21 beads in all, how many bags of each color bead does Alexandra have?
Please help me fast!!
Answer:
4 bags of purple beads and 3 bags of indigo beads.
Step-by-step explanation:
Total number of beads = 21 beads'
Total bags of beads = 4 bags
Purple beads = 3 purple beads
Indigo beads = 6
Let x be each bags of purple beads
Let y be each bags of indigo beads
Since there are 4 bags of bead then;
x + y = 4 ....1
If some of the bags contain 3 purple beads and the rest contain 6 indigo beads, then;
3x + 6y = 21
x + 2y = 7.....2
Subtract 1 from 2
y - 2y = 4 - 7
-y = -3
y = 3
Sunce x + y =7
x = 7-y
x = 7-3
x = 4
Hence there are 4 bags of purple beads and 3 bags of indigo beads.
Is this the right answer
Answer:
yes that would be correct
Step-by-step explanation:
4 + 4 is 8
can someone answer please I don't understand
Answer:

Morgan's mom wants to borrow $720 to buy a new computer. The store will charge her 8% simple interest for one year. How much will she have to pay back if she pays the full amount in one year?
Answer:
$777.60
Step-by-step explanation:
8/100 = 0.08
0.08 * 720 = 57.6
57.6 + 720 = 777.6
Answer:
Step-by-step explanation:
8/100*720=5760/100
=$57.6
$720-$57.6=$662.4
she will pay back $662.4.
You are given two algebraic equations, y = 3x, and 2y = x + 20. Solve for x and y.
Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
y=-12
I GIVE BRAINLIEST!
Explain your answer please!!
Answer:
y=3x-1
Step-by-step explanation:
First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.
(2,5) (10,29)
The equation for slope is m=y2-y1/x2-x1
m=29-5/10-2
m=24/8
m=3
Now, we will find the variable B.
5=3(2)+b
5=6+b
-1=b
That's how we get the equation!
y=3x-1
Answer:y= 3x-1
Step-by-step explanation:
m= y2-y1/ x2-x1=
29-5/10-2=3
Now,use: y-y1= m(x-x1)
y-5=3( x-2)
y= 3x-1

Write the first three terms in the sequence given by the formula an = 8n + 4
Answer:
[tex]a_{1}[/tex] = 12
[tex]a_{2}[/tex] = 20
[tex]a_{3}[/tex] = 28
Step-by-step explanation:
In order to find the values of the first three terms of this sequence we would have to substitute in the "n" values for the first three terms that we mention earlier so. So in order to find the value of the first term we will substitute n with 1 (since the first term will be written as [tex]a_{1}[/tex], and as you see 1 will be equal to n, use the same logic for the other three terms) , in order to find the value of the second term the n would be substituted with 2, and for the third value we will substitute n with 3.
[tex]a_{1}[/tex] = 8 x 1 + 4
[tex]a_{1}[/tex] = 8 + 4
[tex]a_{1}[/tex] = 12
Then.......
[tex]a_{2}[/tex] = 8 x 2 + 4
[tex]a_{2}[/tex] = 16 + 4
[tex]a_{3}[/tex] = 20
And finally .......
[tex]a_{3}[/tex] = 8 x 3 + 4
[tex]a_{3}[/tex] = 24 + 4
[tex]a_{3}[/tex] = 28

It is thought that not as many Americans buy presents to celebrate Valentine's Day anymore. A random sample of 40 Americans yielded 22 who bought their significant other a present and celebrated Valentine's Day. Estimate the true proportion of all Americans who celebrate Valentine's Day using a 98% confidence interval. Express the answer in the form the point estimates /- the margin of error.
Answer:
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
(0.3672 , 0.7328)
Step-by-step explanation:
Explanation:-
Given Random sample size n =40
Sample proportion
[tex]p = \frac{x}{n} = \frac{22}{40} = 0.55[/tex]
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
[tex](p-Z_{\alpha } \sqrt{\frac{pq}{n} } , p + Z_{\alpha } \sqrt{\frac{pq}{n} } )[/tex]
The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
[tex](0.55-2.326\sqrt{\frac{0.55 X0.45}{40} } , 0.55 + 2.326\sqrt{\frac{0.55 X0.45}{40} } )[/tex]
( 0.55 - 0.1828 , 0.55 + 0.1828)
(0.3672 , 0.7328)
Answer:
Step-by-step explanation:
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
( 0.55 - 0.1828 , 0.55 + 0.1828)
(0.3672 , 0.7328)
