Answer:
4 hours
Step-by-step explanation:
Since the initial fee is $90, you will subtract $90 from $330, getting $240. Since every hour after 1 hour is $60, you would divide $240 by $60 getting 4 hours
Answer:
m∠V ≈ 61°
Step-by-step explanation:
The hypotenuse and the side opposite the angle of interest are given. The relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(V) = XW/XV = 7/8
The inverse sine function is used to find the angle:
V = arcsin(7/8) ≈ 61°
The Formula of the relation is M = 8AT.
The mass of the metal sheet is 960 g.
The expression below shows the variation between the mass of the sheet (M), Area of the Sheet(A), and thickness (T).
Proportionality:
Removing the proportionality sign,
Where:
- K = constant of proportionality.
make K the subject of the equation:
- K = M/KT.................... Equation 1
From the question,
Given:
- M = 200 g
- A = 250 cm²
- T = 1 mm = 0.1 cm
Susbtitute into equation 1
- K = 200/(250×0.1)
- K = 8 g/cm³
Formula:
- M = 8AT................. equation 2
Hence the formula of the relation is M = 8AT
If,
- A = 400 cm²
- T = 3 mm = 0.3
Substitute these values into equation 2
Hence, the mass of the metal sheet is 960 g

Answer:
A: 357
(1) 9641
Step-by-step explanation:
With A you really just want to go from the smallest number up so it would be the smallest number possible.
<em>EX.</em> 357 vs. 736 357 is smaller
With 1 you have to go from the highest number to lowest number to get the biggest answer possible.
<em>Ex.</em> 9641 vs. 1946 9641 is larger.
Answer:$143.84Step-by-step explanation:Given the following question:Initial price of the chair was $124....Marked up 16% (which means the price has increased by 16%)Find the new price of the chair...In order to find the answer, we find 16% of a given number in till it equals 124 which was the initial price.16% of 143.84 is 124143.84 is already rounded to the nearest centWhich means the new price of the chair is "$143.84"
