Can I get help with question 6-9
For 6 I’ve already done it I just need assistance and see if I did it correctly
Answers
Answer:
Step-by-step explanation:
6)For question 6 you have the right idea but as the new image is bigger than the pre-image the scale factor would be 3/1
7)You have the right answer but the fraction can be simplified to 2
8)I think this question is asking for the angle in the triangle on the left that is the same as the one on the right so from left to right,
F=R G=S H=T
FG=RS GH=ST FH=RT
9)The scale facto for the longest edge here is 2 but the scale factor for the shortest edge is 18/8 which is equal to 9/4 so the are not congruent as they have two different scale factors. Answer) no
10) the triangles are similar as angle a=n and 55+35+90 = 180 so yes they are similar
Hope this helps :)

Step-by-step explanation:
We solve this equation by combining like terms [tex](-x+8x)=7x[/tex]
Now we rewrite the equation [tex]\frac{7x-12}{x^2-4x-12}[/tex]
We factorize [tex]x^2-4x-12[/tex] and we get [tex](x-6)(x+2)[/tex]

How much should you invest at 2.6% simple interest in order to earn $75 interest in 8 months?
Answers
Answer: Total interest will $1800 after 5 years.
Step-by-step explanation: It is given that the principle amount is $6000.
Rate of interest rate is 6% per annum.
Total interest is $1800.
Formula for simple interest is
Where, P is principle, r is rate of interest in percent and t is time in years.
Substitute P=6000, r=6 and I=1800 in the above formula.
Divide both sides by 360.
Therefore the total interest will $1800 after 5 years.

8. A freight company charges a flat insurance fee to deliver a package anywhere in the continental United States, plus an additional charge for each pound the package weighs. The graph shows the relationship between the weight of the package and the total cost to ship it. Based on the graph, how much would it cost to ship a . 25-pound box?
(A) $37.00
(B) $48.00
(C) $62.50
(D) $74.50
Answers
Answer:
D 74.5
Step-by-step explanation:
Solution 1:
Observing the graph we know that when weight is 0lb we need to pay a $12 flat fee.
When weight=2 lb we notice that the total cost would be $17.
Take out the flat fee:
17-12 = $5.
So, for every 2 lb we need to pay an extra $5; therefore for every lb we need to pay $2.5.
25lb * $2.5/lb = $62.5
Add flat fee: 62.5+12=$74.5
Solution 2:
use linear equation to solve the problem.
1. Find the equation of the graph.
- pick 2 pts (0,12) and (2, 17)
2. Set up equation:
[tex]y=ax+b[/tex] and since the graph goes through (0,12)
thus [tex]y=ax+12[/tex]
3. plug in
- Plug in (2,17)
- [tex]17=2a+12[/tex] and [tex]a=2.5[/tex]
- so [tex]y=2.5x+12[/tex] where x is the weight and y is the total cost in dollar.
4. solve for x=25
[tex]y=2.5*25+12=74.5[/tex]

Answer:

Step-by-step explanation:
You want the equation of a line between the points (0, 0) and (20, 60). The slope of that line is ...
m = (y2 -y1)/(x2 -x1) = (60 -0)/(20 -0) = 60/20 = 3
The y-intercept is 0, so the slope-intercept equation of the line is ...
h(x) = 3x

In the series finale of 'Breaking Wind', ratings
were up 125% from last year's season finale.
10.5 million people watched this year. How
many people watched last year?
Answers
Answer:
3937500
Step-by-step explanation:
People watched last year = x
if ratings were up 125% x increased by x and 25% of x
25% of 10.5 million is 2625000
x increased by itself and 2625000
x*2+2625000 = 10500000
cancel out 2625000 by subtracting to both sides
10500000 - 2625000 = 7875000
x*2 = 7875000
cancel out 2 by dividing 2 on both sides
7875000/2 = 3937500
x = 3937500
A sample of 50 drills had a mean lifetime of 12.17 holes drilled when drilling a low-carbon steel. Assume the population standard deviation is 6.37.Construct a 95% confidence interval for the mean lifetime of this type of drill
Answers
Using the z-distribution, it is found that the 95% confidence interval for the mean lifetime of this type of drill, in holes drilled, is (10.4, 13.94).
We are given the standard deviation for the population, hence, the z-distribution is used. The parameters for the interval is:
Sample mean of [tex]\overline{x} = 12.17[/tex]Population standard deviation of [tex]\sigma = 6.37[/tex]Sample size of [tex]n = 50[/tex].The margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which z is the critical value.
We have to find the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.
In this problem, [tex]\alpha = 0.95[/tex], thus, z with a p-value of [tex]\frac{1 + 0.95}{2} = 0.975[/tex], which means that it is z = 1.96.
Then:
[tex]M = 1.96\frac{6.37}{\sqrt{50}} = 1.77[/tex]
The confidence interval is the sample mean plus/minutes the margin of error, hence:
[tex]\overline{x} - M = 12.17 - 1.77 = 10.4[/tex]
[tex]\overline{x} + M = 12.17 + 1.77 = 13.94[/tex]
The 95% confidence interval for the mean lifetime of this type of drill, in holes drilled, is (10.4, 13.94).

Answers
Answer:
The first mechanic charges $45/hour while the second mechanic charges $50/hr
Step-by-step explanation:
X = rate of first mechanic
Y = rate of second mechanic
X + Y = 95 ---> Y = 95 - X
20X +5Y = 1150
Substituting the first equation into the second,
20X + 5(95 - X) = 1150
20X + 475 - 5X = 1150
15X + 475 = 1150
15x = 1150 - 475
15x = 675
X = 675/15 = 45 --> y = 95 - 45 = 50
CHECK: Plugging these results into the second equation:
20*45 + 5*50 = 900 + 250 = 1150
YES! Success! It checks!
So the first mechanic charges $45/hour while the second mechanic charges $50/hr! :)
