The order of operations is PEMDAS; which stands for Parenthesis, Exponents, Multiplication and Division, and Addition and Subtraction; this is the order used to solve expressions, equations, and inequalities.
Answer:
5√3
Step-by-step explanation:
The ratio of side lengths in a 30-60-90 triangle is ...
1 : √3 : 2
__
Multiplying by 5, we have ...
1 : √3 : 2 = x : y : 10 = 5 : 5√3 : 10
The value of y is 5√3.
_____
<em>Additional comment</em>
y is the side adjacent to the 30° angle, so can be found from ...
Cos = Adjacent/Hypotenuse
Adjacent = Cos × Hypotenuse . . . . . multiply by hypotenuse
y = cos(30°)×10 = (√3)/2 × 10 . . . . . . substitute corresponding values
y = 5√3
__
The value of x is 5.
for each inch is 5 feet, so for each 0.5 aka 1/2 inch, it would be 2.5 inches
2in: 5+5=10ft
2.5in: 5+5+2.5=12.5ft
or just simply mutiply by 2
2(5)= 10ft
2.5 inches so 2.5(5)=12.5
The dimensions of the actual room are 10 feet by 12.5 feet
Answer: 26
Step-by-step explanation:
First Data: (4 - 7)^2
Second data: (6 - 7)^2
Third Data: (11 - 7)^2
So the SST is (4 - 7)^2 + (6- 7)^2 + (11 - 7)^2 = 9 + 1 + 16 = 26
Hope this helps! :)
Answer:
Demetrius's account is $84 higher after the two transactions
Step-by-step explanation:
Let
x -----> original amount in Demetrius's account
y ----> amount in Demetrius's account after the deposit and the withdraws
we know that
The amount in Demetrius's account after the two transactions must be equal to the original amount in Demetrius's account plus the deposit minus the withdraws
so
therefore
Demetrius's account is $84 higher after the two transactions
