What is the value of y?
Answer:
44
Step-by-step explanation:
180-88=92 (linear pair)
y+y+92=180 (Angle sum property)
y+y=180-92
y+y=88
y=88/2
y=44
A line passes through
(-1, 7) and (2, 10) -
Which answer is the equation of the line?
a -3 + y = 12
B - 2 + y = 8
c -3x + y = 16
d -3.2 + y = 4
Answer:
Step-by-step explanation:
technically none of those, i'm pretty sure that in [tex]y=mx+b[/tex] form it would be [tex]y=x+8[/tex] but in the form of the answer choices it would be [tex]-1x+y=8[/tex] .
I don't know if i'm wrong or the answer choices are, but I still hope this helps!

If PR=40, what are PQ and QR?
Answer:
B
Step-by-step explanation:
I did it in my head but pretty much just add the 5x-2 and x+ 12 then set it equal to 40. u get x = 5. plug x back in and you get 23 and 17
Answer:
The answer is B
Step-by-step explanation:
5x - 2 + x + 12 = 40
6x + 10 = 40
6x = 30
x = 5
5(5) - 2
25 - 2
PQ = 23

–14
–2
2
14
Answer:
-2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
Adding a negative number to a positive number will give us a negative number, so we can eliminate 2 and 14. 8 - 6 is 2. So we make the 2 negative which gives us -2.

Suppose that the longevity of a light bulb is exponential with a mean lifetime of eight years. Seventy percent of all light bulbs last at least how long?
Using the exponential distribution, it is found that 70% of all light bulbs last at least 2.85 years.
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
In this problem, the mean lifetime is of 8 years, hence [tex]m = 8, \mu = \frac{1}{8} = 0.125[/tex].
Seventy percent of all light bulbs last at least x, considering that [tex]P(X > x) = 0.7[/tex].
Hence:
[tex]P(X > x) = 0.7[/tex]
[tex]e^{-0.125x} > 0.7[/tex]
[tex]\ln{e^{-0.125x}} > \ln{0.7}[/tex]
[tex]-0.125x > \ln{0.7}[/tex]
[tex]x > -\frac{\ln{0.7}}{0.125}[/tex]
[tex]x > 2.85[/tex]
70% of all light bulbs last at least 2.85 years.

Answer:
Area= 144ft^2
Step-by-step explanation:
Finding an area of a parallelogram is base times height
The base would be 12+6 which would be 18
The height is 8
18*8
Answer:
144 square feet
Step-by-step explanation:
This is the answer because:
1) First, the area of the parallelogram is base x height
2) The base is the lower part of the parallelogram. 6 and 12 are the base. You have to add 12 and 6 to get the full and correct length for the base
12 + 6 = 18
3) Now, we just multiply 18 and 8 which is 144
18 x 8 = 144

Mrs lane took a survey of the types of pants her students were wearing. She collected the data of the types of pants her students were wearing, what percent of her students were wearing shorts? 14 were wearing jeans, 9 were wearing shorts and 2 were wearing capris. please say it in %
Answer:
= 21
Step-by-step explanation:
Now percentage of students wearing shorts = (9/21) * 100
= (3/7) * 100
= 300/7
= 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.

Answer:
[tex]\huge\boxed{x=8a}[/tex]
Step-by-step explanation:
In order to make the equation [tex]\frac{3}{a}x-4=20[/tex] into terms of x, our goal is to get x isolated on one side of the equation.
Let’s simplify this equation by reversing it until we get x = ___.
Add 4 to both sides:
[tex]\frac{3}{a}x - 4 + 4 = 20+4\\\\\frac{3}{a}x = 24[/tex]
Multiply both sides by a:
[tex]\frac{3}{a}x \cdot a=24 \cdot a\\\\3x = 24a[/tex]
Divide both sides by 3:
[tex]3x \div 3 = 24a \div 3\\\\x = 8a[/tex]
Now we have x isoalted with a term equal to it. Therefore, x = 8a.

a worm travels 500 feet in one hour. how many inches does it travel per minute?
Answer:
100 inches
Step-by-step explanation:
Well, 500 feet is 6,000 inches. So, to find out how far does the worm travel in 1 hour (60 minutes) we would have to divide: 6,000 ÷ 60 minutes (1 hour) = 100. So, the worm can travel 100 inches in 1 minute

Answer:
33/24 or 11/8, or 1 9/24 or 1 3/8
Step-by-step explanation:
you have to find a common denominator between the two fractions. The least common denominator for 9 and 8 is 24. Since you multiply 9 by 3 to get 24, you multiply 5 by 3 and get 15. You now have the fraction 15/24. Since you multiply 8 by 3 to get 24, you also multiply 6 by 3, which is 18. You now have the fraction 18/24. You add 15/24 and 18/24, and you get 33/24, which can be simplified to 11/8. It can be shown as 1 9/24 as a mixed number, and simplified to 1 3/8.
