So first you would multiply 18 and 20% and with that answer you have to dive by 100 because that's the whole for a percent number, your answer should be $3.60
Answer:
-0.8 or 991/10
(also it can be 10%)
Step-by-step explanation:
991
——— = 99.10000
10
Step by step solution :
Step 1 :
9
Simplify ——
10
Equation at the end of step 1 :
9
100 - ——
10
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 10 as the denominator :
100 100 • 10
100 = ——— = ————————
1 10
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
100 • 10 - (9) 991
—————————————— = ———
10 10
Final result :
991
——— = 99.10000
10
Answer: B
<u>Step-by-step explanation:</u>
x³ - 3x² + 16x - 48 = 0
→ x²(x - 3) + 16(x - 3) = 0
→ (x² + 16) (x - 3) = 0
→ (x² - (-16)) (x - 3) = 0
→ (x - 4i)(x + 4i)(x - 3) = 0
→ x - 4i = 0 x + 4i = 0 x - 3 = 0
→ x = 4i x = -4i x = 3
2 imaginary roots and 1 real root
Area of a rectangle is equal to length times width so the equation:
To find w, you would solve for it in this equation by dividing by l on both sides like so:
Which leaves you with:
So to find width you
divide the Area by the length:
