Answer:
Step-by-step explanation:
Use SOH-CAH-TOA
Sin(25º) = x/10 (x being the height of the triangle)
x= Sin (25º) (10)
x = 4.23
Now for the base:
Cos (25º) = x/10
x = cos(25º)(10)
x = 9.06
Now solve for the area using 1/2bh
19.2 in^2

Answer:
The rate of change is y with respect to x is
<em></em>
Step-by-step explanation:
Given
Required
Determine the rate of change of y w.r.t x
First, make y subject of formula
Divide through by 4
Next, we differentiate the above w.r.t to x
The result of the differentiation is the solution to the question
<em>Hence, the rate of change is y with respect to x is </em><em></em>
Answer:
20%
Step-by-step explanation:
$53.64 - $42.91
= 10.73
10.73/53.64*100
Answer:
42 minutes
Step-by-step explanation:
70% x T = 98
7T/10 = 98
7T = 980
T = 140 mins
140 - 98
= 42 minutes
Answer:
The freezing temperature of water in degrees Fahrenheit is 32 degrees Fahrenheit
Step-by-step explanation:
In this question, given the equation that shows the relationship between the two temperature scale, we are asked to give the temperature in Fahrenheit in which water freezes
To calculate this, we simply substitute 0 into the equation
The equation we are substituting into is ;
F = 32 + 1.8c
F = 32 + 1.8(0)
F = 32 + 0
F = 32 degrees Fahrenheit
