Answer:
Step-by-step explanation:
Sin= o/h = 23/40 = 0.575 = sin^-1(0.575) = 35.1 degrees
Cos = a/h = 37/40 = 0.925 = cos^-1(0.925) = 22.3 degrees
Tan= o/a = 23/37 = 0.622 = tan^-1(0.622) = 31.9 degrees
The system of equations that can be used to determine the number of small tables and the number of large tables the designer will make is:
y -x = 8
$12y - $6x = $236
<h3>Defining the variables </h3>
Let:
x = number of large tables the designer can make.
x = number of small tables the designer can make.
<h3>Simultaneous equations</h3>
Simultaneous equations are sets of equations that must be solved together in order to determine the required variables. Methods of solving simultaneous equations include:
- Elimination method
- substitution method
- Graph method

Answer:
<h3>★ <u>11/</u><u>3</u><u>0</u> is the right answer. ★</h3>
Step-by-step explanation:
- Number of male students who got 'A' in the test is 11
- Number of female students who got 'A' in the test is 19
- Total students who got 'A' in the test is 30
- Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = <em><u>11/</u></em><em><u>3</u></em><em><u>0</u></em>
Answer: Width would become 21 and length would become 33. Original perimeter is 100, increased perimeter is 108 which is a 7.69% increase
Answer:
B) -5
Step-by-step explanation:
let the number be x
2x=x-5
take x to the other side
2x-x=-5
×=-5
