Step-by-step explanation:
Ok so,

12 - 10t + 13t = -13t + 13t - 18
12 + 3t = -18
12 - 12 + 3t = -18 - 12

An isosceles triangle has base angles that each measure 69o. Which equation can be used to find x, the measure of the third angle?
a
138 + x = 180
b
69 + x = 180
c
138 + 2x = 180
d
2x + 69 = 180
Answers
Answer:
a. 138 + x = 180
Step-by-step explanation:
Because the angles given are 69+69
which equal 138
and x being the missing angle
finally the total of all angles in a triangle = 180

Please help due tmr. Find c.

Answers
Answer:
c = 14.9 cm
Step-by-step explanation:
Applying the Law of Sines, we would have the following:
c/sin(C) = b/sin(B)
c = ??
C = 180 - (150 + 12) = 18°
b = 10 cm
B = 12°
c/sin(18) = 10/sin(12)
Multiply both sides by sin(18)
c = (10*sin(18))/sin(12)
c = 14.9 cm (nearest tenth)

What is the perimeter of ABCD?
Answers
Answer:
360°
Step-by-step explanation:
Based on what I know that the total of degrees has to be 360°. So, two sides of the rhombus have to have two acute angles and two obtuse angles. So, the Image shows that the 63° is an acute angle. So, multiply 63 by 2 which is 126. Then subtract 126 from 360 which is 234. Then, divide 234 by 2 which is 117. Lastly, add 63 with 63 and 117 with 117 which is 360.
Hopefully, you understand.

Jason walked 6 miles in 2 hours. At this same rate, what is the total number of miles Jason could hike in 9 hours?
Answers
Answer:
17 hours is the total of miles he walked
Answer:
Step-by-step explanation:
rn = 6 miles in 2 hrs
we want 9 hours
Per hour it will be 3 miles
3 miles = 1 hr
6 miles = 2 hrs
9 miles = 3 hrs
12 miles = 4 hrs
15 miles = 5 hrs
18 miles = 6 hrs
21 miles = 7 hrs
24 miles = 8 hrs
27 miles = 9 hrs
All you basically had to do is multiply the 9 hours with 3 since that's how much you get per mile, and then you get your total of 27 miles

If sin theta = -2/3 which of the following are possible?
Answers
Answer:
a
Step-by-step explanation:
The possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The trigonometric function, sin θ = -2/3
We know that [tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]
So, opposite = -2, hypotenuse = 3
The other side of the right triangle adjacent side can be found by using the Pythagoras theorem,
[tex]adjacent=\sqrt{hypotenuse^{2} -opposite^{2} }[/tex]
⇒ [tex]adjacent=\sqrt{3^{2} -(-2)^{2} }[/tex]
⇒ [tex]adjacent=\sqrt{9-4 }[/tex]
⇒ [tex]adjacent=\sqrt{5}[/tex]
Now, [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex] and [tex]tan \theta = \frac{opposite}{adjacent}[/tex]
Then, [tex]cos \theta = \frac{\sqrt{5} }{3}[/tex]
[tex]sec \theta = \frac{1}{cos \theta}[/tex]
⇒ [tex]sec \theta = \frac{1}{\frac{\sqrt{5} }{3} }[/tex]
⇒ [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex]
[tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex]
Hence we can conclude that the possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.

The tolerance limits for a circuit breaker are Amperes. This means that any circuit breaker that breaks at an amperage less than 39.5 breaks at too low a level and any that breaks at an amperage greater than 40.5 breaks at too high a level. If a shipment of circuit breakers possesses break points that are normally distributed with mean 39.3 and standard deviation 0.2, then what percentage of the shipment is defective
Answers
Answer:
84.13% of the shipment is defective
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Normally distributed with mean 39.3 and standard deviation 0.2
This means that [tex]\mu = 39.3, \sigma = 0.2[/tex]
What percentage of the shipment is defective
Less than 39.5 or greater than 40.5.
Less than 39.5:
This is the pvalue of Z when X = 39.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{39.5 - 39.3}{0.2}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a pvalue of 0.8413.
Greater than 40.5:
1 subtracted by the pvalue of Z when X = 40.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{40.5 - 39.3}{0.2}[/tex]
[tex]Z = 6[/tex]
[tex]Z = 6[/tex] has a pvalue of 1
1 - 1 = 0
Total:
0.8413 + 0 = 0.8413
84.13% of the shipment is defective

A car dealership increased the price of a certain car by .13% The original price was 38,600.
Answers
Answer:
$43,618
Step-by-step explanation:
Find the price of the car after this price increase. Multiplying $38,600 by 1 yields the original price, whereas multiplying it by 0.13 yields the price increase. Thus, we can answer this question by multiplying $38,600 by 1.13:
$38,600*1.13 = $43.618. This is the price for which the dealer sells the car.
