a. Find the value of g.
Answer:
Step-by-step explanation:
u put the gs with each other by flipping the one that was changed
3.6g-1.6g=8-2
2g=6
g=6/2
g=3
Answer:
g=3
Step-by-step explanation:
3.6g+2= 1.6g+8
-1.6g -1.6g
2g+2= 8
-2 -2
2g=6

Circle A is shown with a central angle marked 37 degrees and the radius marked 10 inches. Which of the following could be used to calculate the area of the sector in the circle shown above?
π(10in)237 over 360
π(10in)37 over 360
π(37in)210 over 360
π(37in)10 over 360
Answer:
π(10in)237 over 360
Step-by-step explanation:
i took the same test and got it right :)
The area of the sector of the circle is [tex]\frac{100\pi }{360} *37[/tex]
To understand more, check below explanation.
Area of the sector of the circle:To find the area of the sector of circle, we use formula,
[tex]Area=\frac{\pi r^{2} }{360} *\theta[/tex]
where r is radius of circle and [tex]\theta[/tex] is the central angle.
Given that, r = 10 inches, [tex]\theta[/tex] = 37 degrees.
Substitute above values in above formula.
[tex]Area=\frac{\pi (10)^{2} }{360} *37\\\\\\Area=\frac{100\pi }{360} *37[/tex]

Step-by-step explanation:
write the coordinates of the vertices after a reflection over the line x=-2
d(-10,0)
e(-10,2)
f(-5,2
g(-5,0)
Given:
The vertices are d(-10,0), e(-10,2), f(-5,2) and g(-5,0).
To find:
The coordinates of the vertices after reflection over the line x=-2.
Solution:
If figure reflected over the line x=a, then
[tex](x,y)\to (2a-x,y)[/tex]
Here, the figure is reflected over the line x=-2, then
[tex](x,y)\to (2(-2)-x,y)[/tex]
[tex](x,y)\to (-4-x,y)[/tex] ...(i)
Now,
For point d,
[tex](-10,0)\to (-4-(-10),0)[/tex]
[tex](-10,0)\to (-4+10,0)[/tex]
[tex](-10,0)\to (6,0)[/tex]
Similarly,
For point e,
[tex](-10,2)\to (-4-(-10),2)=(6,2)[/tex]
For point f,
[tex](-5,2)\to (-4-(-5),2)=(1,2)[/tex]
For point g,
[tex](-5,0)\to (-4-(-5),0)=(1,0)[/tex]
Therefore, the coordinates of vertices after a reflection over the line x=-2 are d prime (6,0), e prime (6,2), f prime, (1,2) and g prime (1,0).

The salaries of pharmacy techs are normally distributed with a mean of $32,000 and a standard deviation of $3,000. If a pharmacy tech is selected at random, what is the probability they make more than $39,000?
Answer:
The probability is [tex]P( X > 39000) =0.01[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = \$ 32000[/tex]
The standard deviation is [tex]\sigma = \$ 3000[/tex]
Generally the probability that they make more than $39,000 is mathematically represented as
[tex]P( X > 39000) = P( \frac{X - \mu }{\sigma } > \frac{39000 - 32000}{3000} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P( X > 39000) = P(Z > 2.33 )[/tex]
From the z table the area under the normal curve to the right corresponding to 2.33 is
[tex]P(Z > 2.33 ) = 0.01[/tex]
So
[tex]P( X > 39000) =0.01[/tex]
The probability they make more than $39,000 is 1%
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation\\\\Given \ that:\\\\\mu=32000,\sigma=3000.For\ x>39000:\\\\z=\frac{39000-32000}{3000}=2.33[/tex]
From the normal distribution table:
P(x > 39000) = P(z > 2.33) = 1 - P(z < 2.33) = 1 - 0.9901 = 0.0099 = 1%
Therefore the probability they make more than $39,000 is 1%

When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3

Cameron wants to buy a skateboard. he has $89, Which is $17 more than he needs. Which equation can be used to determine how much the skateboard costs
Answer:
The answer to this question is $72. The equation is x + 17 = 89
Step-by-step explanation:
Equation: x + 17 = 89
Cameron has $89 so 89 would go behind the equal sign.
He has 17 dollars more than he needs. Whenever more is used that usually indicates that it will be a plus sign. So we will do + 17 = 89.
Finally we need to add the x to complete the equation. This will be shown as x + 17 = 89.
If you solve this equation it will equal x = 72.
If this helped you please subscribe to The Game Rater. Thank you.
Answer:
89-17
Step-by-step explanation:
To find how much Cameron’s skateboard costs you need to take away 17 from your starting amount as you have more. Meaning we subtract the 17 to find how much the skateboard costs.
