Answer:
k=172.2
Step-by-step explanation
When you search up (0.6888) into a fraction calculator you get (861/1250),
which clearly needs to be simplified. Easy find the LCD. We already know that 1250 needs to be 25. So, divide (1250/25=50)
So know we know that the LCD is 50. Now we need to divide 861 by the LCD. (861/50=172.2)
k=172.2
Answer:
19 points
Step-by-step explanation:
convert points to percents:
20 points = 100%
19 points = 95%
18 points = 90%
17 points = 85%
percent-wise, her average prior to another quiz is 92.5
so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points
Answer:
Area = 27 cm²
Step-by-step explanation:
let L be the length of the rectangle
w the width
P the perimeter
A the area
<u>Formulas</u> :
P = 2×(L + w)
A = L × w
<u>We are Given</u> :
L = 3w
P = 2×(L + w)
⇔ 24 = 2×(3w + w)
⇔ 24 = 2×4w
⇔ 24 = 8w
⇔ w = 24/8 = 3
Then
L = 3w = 3×3 = 9
We obtain L = 9 and w = 3.
Then
A = L × w
= 9 × 3
= 27
