Answer: x=32
Step-by-step explanation:
Because a triangle is 180°, the missing angle in the triangle would be 60°.
Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.
Answer:
(29.14 ; 30.06)
Step-by-step explanation:
Given that'
Sample size (n) = 57
Mean (m) = 29.6
Population standard deviation (σ) = 2.7
Confidence interval = 80%
= (1 - 0.8) / 2 = 0.1
Mean ± z * σ/√n
Using the Z probability calculator : Z0. 1 = 1.28
Hence,
29.6 ± 1.28 * (2.7 / √57)
29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)
29.142241664 ; 30.057758336
(29.14 ; 30.06)

Answer:
is the inequality that reflect the relationship.
Step-by-step explanation:
Given:
Charge for rental = $100
Additional charge = $ 35
Minimum amount that can be spent = $280
To Find:
equations or inequalities that reflect the relationship = ?
Solution:
Let x be the minimum number of hours
then the charge will be
100 + (number of hours)(additional cost per hour)
That is
100 + 35x
Now the minimum charge amount is $280 So, The charge can be 280 or more than 280
