Answer:
x = 8
Step-by-step explanation:
Two tangent segments to a circle from the same external point are congruent, thus
WP = WQ , that is
3x - 6 = x + 10 ( subtract x from both sides )
2x - 6 = 10 ( add 6 to both sides )
2x = 16 ( divide both sides by 2 )
x = 8
According to the United States Census Bureau. Just about 5 1.5% of the adults in America are women. What would you say is the probability that the next adult you run into is female? What's the probability of that person being male?
Answer:
[tex]P(F) = 0.515[/tex]
[tex]P(M) = 0.485[/tex]
Step-by-step explanation:
Given
[tex]Female = 51.5\%[/tex]
Solving (a): Probability of running into a female
To do this, we simply convert the given proportion to decimal
[tex]P(F) = 51.5\%[/tex]
Convert to fraction
[tex]P(F) = \frac{51.5}{100}[/tex]
[tex]P(F) = 0.515[/tex]
Solving (b): Probability of running into a male
Represent this with [tex]P(M)[/tex]
To solve this, we apply the concept of probability complement which states that:
[tex]p + q = 1[/tex]
In this case:
[tex]P(F) + P(M) = 1[/tex]
Substitute 0.515 for P(F)
[tex]0.515 + P(M) = 1[/tex]
Subtract 0.515 from both sides
[tex]0.515-0.515 + P(M) = 1 - 0.515[/tex]
[tex]P(M) = 1 - 0.515[/tex]
[tex]P(M) = 0.485[/tex]

129 129 127 131", and 124
Answer:
125 deg
Step-by-step explanation:
(n - 2)180
n = 7
(7 - 2)180 = 5(180) = 900
900 - 135 - 129 - 129 - 127 - 131 - 124 = 125
Answer: 125 deg

a. -4 and 4b + 4
b. 3x and 1 -3x
Answer:
Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!
Step-by-step explanation:
a. -4 and 4b + 4 = 4b
-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b
b. 3x and 1 - 3x = 1
3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1
A crane lifts a pallet of concrete blocks 7ft from the back of a truck. The truck drives away and the crane lowers the pallet 11ft What is the final position of the pallet relative to where it started in the back of the truck?
Answer:
The position of the concrete relative to its initial position is 4ft behind its initial position
Step-by-step explanation:
Let us analyze the problem following the sequence of events.
First of all, the crane is initially 7 ft from the back of the truck.
Once the truck drives away, the crane lowers the concrete at 11 ft away from the back of the truck.
To get this distance relative to the initial position, we have to subtract the initial position from the final position of the concrete.
This will be
11ft - 7ft = 4 ft
The position of the concrete relative to its initial position is 4ft behind its initial position

Step-by-step explanation:
if the radius is 14cmand The perimeter of the sector is 57.32cm.
what is the size of the angle?
Answer:
120°
Step-by-step explanation:
A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:
Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r
Where θ is the angle which forms the sector and r is the radius of the circle.
Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:
Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r
[tex]57.32=\frac{\theta}{360} *2\pi *14+2(14)\\\\57.32-28=\frac{\theta}{360} *2\pi *14\\\\29.32=\frac{\theta}{360} *2\pi *14\\\\ \frac{\theta}{360}=\frac{29.32}{2\pi *14} \\\\\frac{\theta}{360}=0.33\\\\\theta=120^o[/tex]

Solve for x . 2x=y
X – y=11
3x + 10y= -6
Answer:
(8, - 3 )
Step-by-step explanation:
Given the 2 equations
x - y = 11 → (1)
3x + 10y = - 6 → (2)
Multiplying (1) by 10 and adding to (2) will eliminate the y- term
10x - 10y = 110 → (3)
Add (2) and (3) term by term to eliminate y
13x + 0 = 104
13x = 104 ( divide both sides by 13 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (2)
3(8) + 10y = - 6
24 + 10y = - 6 ( subtract 24 from both sides )
10y = - 30 ( divide both sides by 10 )
y = - 3
solution is (8, - 3 )

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking. How much butter was left after she was done baking?
Answer:
[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.
Step-by-step explanation:
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.
We need to find how much butter was left after she was done baking.
It can be calculated as follows,
Left =
[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]
Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking
