What is the equation, in slope-intercept form,of the line that perpendicular to the line y-4=2/3(x-6) and passes through the point (-2,-2)
Answers
Answer:
y = -3/2x + 1
Step-by-step explanation:
Perpendicular slopes are negative reciprocals of each other.
After you convert that equation to slope-intercept form, you can get the negative reciprocal of the slope and put it in the equation. Then, insert the points(-2,-2) in it and solve it to find c. In this case, it's 1.
in 1997 the population of a small town was 700. If the annual rate of increase is about 0.8%, which value below expresses the population five years later? a.(700)(0.008)^5 B.(700)(1.08)^5 c.(700)(0.08)^5 D. (700)(1.008)^5
Answers
Answer:
D
Step-by-step explanation:
[tex]P(1+r\%)^t[/tex]
[tex]700 \times (1+0.8\%)^5[/tex]
[tex]700 \times (1+0.8/100)^5[/tex]
[tex]700 \times (1+0.008)^5[/tex]
[tex]700 \times (1.008)^5[/tex]
The value expresses the population five years later is (700)(1.008)^5.
We have given that in 1997 the population of a small town was 700.
The annual rate of increase is about 0.8%.
We have to find the population for 5 years
What is the formula for future value?
[tex]F=P(1+r)^t\\\\[/tex]
Here p=700
r=0.8/100=0.008
t=5
Use the above value in the formula so we get,
[tex]F=700(1+0.008)^5[/tex]
[tex]F=700(1.008)^5[/tex]
Therefore option D is correct.

Katherine has two types of iodine in her lab. She has brand 232 iodine, which costs thirty-six cents
per ounce. She also has brand 880 iodine, which costs $2.04 an ounce. How many ounces of each should she use if she wants to make three hundred ninety-three ounces of iodine that cost a total of $255.72?
Answers
Answer:
Number of ounces of iodine 888 brand = 68
Number of ounces of iodine 232 brand = 325
Step-by-step explanation:
Given the following ;
Brand 232:
Cost per ounce = 36cent
Brand 880:
Cost per ounce = $2.04 = 204cent
Assume the following :
Number of ounces of 232 brand = x
Number of ounces of 888 brand = y
Total ounces to be made :
x + y = 393 - - - (1)
Total cost of iodine :
Brand 232 = 36x
Brand 888 = 204y
36x + 204y = 25572 - - - - (2)
From (1)
x = 393 - y - - - - (3)
Substitute (3) into (2)
36(393 - y) + 204y = 25572
14148 - 36y + 204y = 25572
-36y + 204y = 25572 - 14148
168y = 11424
y = 11424 / 168
y = 68
From ; x = 393 - y
y = 68
x = 393 - 68
x = 325
Number of ounces of iodine 888 brand = 68
Number of ounces of iodine 232 brand = 325

subract 5 5/21 from 13 1/7
Answers
Answer:
The answer is 166/21, or 7 19/21
Step-by-step explanation:
First, you would set up the equation, which is:
13 1/7 - 5 5/21
Next, you would turn them into an improper fraction, which is:
92/7 - 110/21
Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:
276/21 - 110/21
Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.
Answer:
7 19/21
Step-by-step explanation:
13 1/7 - 5 5/21
Get a common denominator
13 1/7*3/3 - 5 5/21
13 3/21 - 5 5/21
We need to borrow 1 from the 13 in the form of 21/21
12 +21/21 + 3/21 - 5 5/21
12 24/21 - 5 5/21

Annie is 3 years older than James. (Use J represent James’ age.)
a. Write an expression to represent Annie's Age.
b. If the sum of their ages is 18, write an equation to represent this situation
C. How old is Annie ?
Answers
Answer:
Step-by-step explanation:
James' age = J
a) Annie is 3 years older than James so,
Annies age = 3 +J
b) Sum of their ages is 18 so,
Annies age + James' age = 18
= 3 + J + J = 18
2J = 18-3
J = 15/2 = 7.5
c) Annies age = 3 + J = 3 + 7.5
= 10.5 years
B) J+(J+3)= 18
C)
2J+3= 18
-3 -3
2J= 15
1/2(2J) =(15)1/2
J=7.5
18-7.5= 10.5
Annie is 10.5

This is really weird. None of them seem to be right.
For the first one, it says that -7.5 is greater than or equal to -6.4, which is not true. -7.5 is less than -6.4. The next one is the only one that makes a true comparison, but I don't agree with the "or equal to" part. -7/8 cannot be equal to 7/8. The next one is false, -4 is greater than -8. Finally, the last one is incorrect as well because -4.2 is less than -3.6.
However, if I had to choose one, I'd choose the second option. It's the closest to being correct.

Mardi received an inheritance of $40,000. She invested part at 9% and deposited the remainder in tax-free bonds at 10%. Her total annual income from the investments was
$3700. Find the amount invested at 9%
O A $36,300
OB $29.000
oc 530,000
OD 515,000
Answers
Answer:
The amount invested at 9% is $30,000
Step-by-step explanation:
Mardi received an inheritance of $40,000.
Let x be the amount invested at 9%.
So, Amount invested at 10% = 40000-x
Her total annual income from the investments was $3700.
So, [tex]0.09x+0.1(40000-x)=3700[/tex]
[tex]0.09x+4000-0.1x=3700[/tex]
x=30000
Hence the amount invested at 9% is $30,000

2y=-20
y=-10
x+10=8
x=-2
Answer:
[tex]x = - 2 \\ y = - 10[/tex]
Step-by-step explanation:
[tex]x + y = - 12 \\ x - y = 8[/tex]
[tex]x + y + (x - y) = - 12 + 8 \\ x + y + x - y = - 4 \\ 2x = - 4 \\ \frac{2x}{2} = \frac{ - 4}{2} \\ x = - 2[/tex]

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.
Rolling a sum of 9, there are 4 possibilities, which is a better chance.
Rolling a sum less than 5, there is 6 possibilities, which is a better chance.
Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.
Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.
Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

x = 114°
y = 27
Step-by-step explanation:
To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.
To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.
Answer:
x= 114,
y= 27
Step-by-step explanation:
x= 180 - 66 = 114
6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

3x-1/9y=18
Add 1/9 y to each side
3x-1/9y + 1/9 y=18+ 1/9 y
3x = 18 + 1/9 y

Let y = 27
x= 6+ 1/27 * 27

Complete parts (a) through (d) below.
a. What is the probability that exactly 7 of the selected adults believe in reincarnation?
The probability that exactly 7 of the 8 adults believe in reincarnation is
(Round to three decimal places as needed.)
Answers
Answer:
The probability under the given conditions is found:
P(7) = 0.079
Step-by-step explanation:
Let x be the number of adults who believe in reincarnation.
Adults randomly selected = 8
percentage of adult believe in reincarnation = 40% = 0.4
x follows binomial distribution:
P(x) = [tex]\left(\begin{array}{ccc}n\\x\end{array}\right) (p)^x(1-p)^{n-x}[/tex]
where
n= total people random people selected = 8,
x = selected for the part = 7,
p = probability given = 0.4
P(7) = [tex]\left(\begin{array}{ccc}8\\7\end{array}\right) (0.4)^7(1-0.4)^{8-7}[/tex]
P(7)= (8)(0.0164)(0.6)
P(7) = 0.07872
Rounding off to 3 decimal positions
P(7) = 0.079
