A sock drawer contains 5 different colors of socks. It has 20 white, 10 black, 10 gray, 6 red, and 4 purple. If you reach into the drawer and choose a sock randomly, what is the probability you will get a black sock? P (black) = StartFraction Number of favorable outcomes over Total number of outcomes EndFraction P(black) =
Answer:
1/5
Step-by-step explanation:
Total number of socks = 50( 20+10+10+6+4)
Number of black socks = 10
Therefore, 10/50= 1/5
the probability of getting a black sock is 1/5.

(-2ab^-5)(4a^-2b)^-2
Answer:
-a^5/(8b^7)
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
a^-b = 1/a^b
__
[tex](-2ab^{-5})(4a^{-2}b)^{-2}=(-2ab^{-5})(4^{-2}a^{-2(-2)}b^{-2})\\\\=\dfrac{-2}{16}a^{1+4}b^{-5-2}=\boxed{-\dfrac{a^5}{8b^7}}[/tex]

Answer:
28. m<A=20°, m<B=70°
32. m<A=103°, m<B=77°
Step-by-step explanation:
complementary angle=a+b=90°
supplementary angle=a+b=180°
28. A+B=90°
5x+17x+2=90°
22x+2=90°
22x=90-2
22x=88
22x/22=88/22
x=88/22=4
m<A=5x=5*4=20°
m<B=17x+2=17*4+2=68+2=70°
Check
A+B=90°
20+70=90°
90°=90°
32. A+B=180°
x+11+x-15=180°
2x-4=180°
2x=180+4
2x=184
2x/2=184/2
x=184/2
x=92
m<A=x+11=92+11=103°
m<B=x-15=92-15=77°
Check
A+B=180°
103+77=180°
180°=180°

A map has a scale of
2 in. = 17 mi. If you measured the distance between two cities to
be 19 in. on the map, how many miles would it actually be?
If necessary, round your answer to the nearest tenth.
Answer:
161.5 miles
Step-by-step explanation:
19 inches is 9.5 times 2 inches. So, the actual distance is 9.5 times 17 miles:
9.5 × 17 miles = 161.5 miles

Answer: Choice C
[tex](xy)^{1/2}[/tex] which is equivalent to [tex]\sqrt{xy}[/tex]
===============================================
Explanation:
The exponent for the y term inside the parenthesis is 1/6 and then that expression is raised to the 3rd power. The exponents multiply to (1/6)*3 = 3/6 = 1/2
This means [tex]\left(y^{1/6}\right)^3 = y^{1/2}[/tex]
Having an exponent of 1/2 is the same as applying the square root, so,
[tex]\sqrt{x} = x^{1/2}[/tex]
Meaning,
[tex]y^{1/2}\sqrt{x} = y^{1/2}x^{1/2} = (xy)^{1/2} = \sqrt{xy}[/tex]

what is 3.825 as a fraction with a guide?
Answer:
153/40
Step-by-step explanation:
The first step to finding the fraction is to get rid of the decimal points as fractions do not have decimals. To do this we can multiply it by 1000 which gives us 3825. To have this equal to the original number we add ÷1000 on the denominator which gives us 3825/1000 which is a fraction still equal to the original number (3825÷1000=3.825). Which can further be simplified to 153/40 (both numbers divisible by 25). This is the simplest fraction which can express the number 3.825 (153/40=3.825).

What’s the perimeter of the tabletop in feet?
Answer:
Perimeter = 14.0942 ft (aprox)
Step-by-step explanation:
1 ft = 12 inches
1 inch = 1/12 = 0.08333 ft
4 inch = 4*0.08333 = 0.3333 ft
then:
there are:
4 quarters of circle = 4/4 = 1 complete circleperimeter = 2π r
π = 3.1416
r = radius
perimeter = 2*3.1416*0.3333ft
perimeter = 2.0942 ft (aprox)
4 sides (3ft each)perimeter = 4*3ft
perimeter = 12ft
Total perimeter:
2.0942ft +´12ft = 14.0942 ft

Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.
Answer: Because the a-value is negative.
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
"a" is the vertical stretch-a is a reflection over the x-axish is the horizontal shift (positive = right, negative = left)k is the vertical shift (positive = up, negative = down)Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
is 10/18 in decimal form a terminates or repeating decimal
Hey there! I'm happy to help!
To write a fraction as a decimal, you simply divide the numerator by the denominator.
10÷18=0.55555.... (the 5s never end!)
We see that the 5s repeat forever. This means that this is a repeating decimal.

I need help with Part 2 of the question.
Steps to solve:
6a + 12 = 3(2a + 1) + 5
~Distribute right sides
6a + 12 = 6a + 3 + 5
~Simplify
6a + 12 = 6a + 8
~Subtract 12 to both sides
6a = 6a - 4
~Subtract 6a to both sides
0 = 4
Therefore, there are no solutions.

The point (0, –4) is located
I'm going to assume you're asking where the point is located on a coordinate plane.
We have x = 0 and y = -4.
So, we start at (0, 0) and move down 4 units.
