Answer:
DFG≈26.77°
Step-by-step explanation:
cos = adjacent/hypotenuse
the right half of line DF is 5.
cos⁻¹(5/5.6) = DFG
DFG ≈ 26.77°
Answer:
Bigger number = 42
Smaller number = 10
Step-by-step explanation:
Step 1: Define variables
<em>x</em> = larger number
<em>y</em> = smaller number
Step 2: Write systems of equations
x + 2y = 62
3x = y + 116
Step 3: Rewrite 1st equation
x = 62 - 2y
Step 4: Substitution
3(62 - 2y) = y + 116
186 - 6y = y + 116
186 = 7y + 116
70 = 7y
y = 10
Step 5: Plug in <em>y</em> to find <em>x</em>
x + 2(10) = 62
x + 20 = 62
x = 42
B C=0.1 and D=0.1
I think you ment c not b for the third one so I wrote the answer to
Answer:
18 questions
Step-by-step explanation:
22 questions=55%
??? questions=45%
now what about this:
2 questions=5%
I just simplified the first equation
now 5%*???=45%
5*9=45
then we do the same thing to the other side
2*9 questions=45%
18 questions are left on the survey
