Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = 
, thus
tan30° = 
= 
and
= ( cross- multiply )
b = 7
Answer: 7/3
Step-by-step explanation: let the original real number be x. After moving the decimal point of this real number two digits to the right, the number becomes 100x. The positive difference between the two numbers is 100x - x = 99x. Dividing the difference by 11, we have 99x/11 = 9x, which we are told is 21, so we have the equation 9x = 21/9, which equals 7/3. Thus, the original real number is 7/3.
Given the equation y = kx
Also given that she:
earned $350 after working 40 hours
y = how much earned
x = number of hours
Plug it in
y = kx
350 = k(40)
divide both sides by 40 to find out how much k is
8.75 = k
k = 8.75 so your answer is A.) 8.75
Hope this helps :)
Answer:
12(5 - 3w)
Step-by-step explanation:
60 - 36w
The GCF of 60 and 36w is 12.
60 - 36w = 12(5 - 3w)
