11/2 + 3/4 = 22/4 + 3/4 = 25/4
(25/4) / (1/8) = 25/4 * 8/1 = 200/4 = 50 students
Answer:
2/5 m or 4 dm
Step-by-step explanation:
The fraction 4/10 can be reduced by removing a factor of 2 from numerator and denominator. The length could be expressed as 2/5 m.
The metric system has unit prefixes that make it easy to choose appropriate units for almost any measurement. Apparently Christina wants to use 1/10 m as her unit of measurement. That length is also called a "decimeter." So, Christina's measurement could be expressed in very simple form as 4 dm.
_____
A decimeter is not a particularly common unit in everyday use, though it is reasonably useful for many purposes.* More conventionally, lengths in that range are expressed in centimeters, so Christina's measurement could also be described as 40 cm.
____
* I like units of decimeters for volume calculations, because a cubic decimeter is 1 liter.
Answer:
150 percent
Step-by-step explanation:
30/20. Multiply both sides by 5. 150/100. 30 is %150 of 20
Answer:
A. -3√7/7
Step-by-step explanation:
We have the equation in trigonometry as following:
with (cos x)^2 different from 0, we have:
=>
As (cos θ) = √7/4 ≠ 0, so that we can replace θ into the above equation, we could have:
(tan θ)^2 = 1/[(cos θ)^2] -1
=> (tan θ)^2 =
=>(tan θ)^2 = 16/7 - 7/7 = 9/7
<em>=> tan θ = (3√7)/7 </em>
<em>or tan θ = - (3√7)/7 </em>
<em />
As θ is in quadrant IV, so that its tangent has negative value
=> tan θ = -3√7/7
So that the correct answer is A
Answer:
$1.46
Step-by-step explanation:
To find the original price of the game, write a proportion. $1.54 is the amount after a 5.5% tax rate. This means he paid 105.5% on the original price.
Find y by cross multiplying numerator and denominator of each fraction.
1.54(100) = 105.5y
154 = 105.5y
1.46 = y
