Hello,
900=2²*3²*5²
2567=17*151
GCD(900,2567)=1
HCF(900,2567)=2²*3²*5²*17*151=2310300
Proof: GCD*HCD=900*2567
I am thinking you mean 93 to represent William's scores of 91, 92, and "q3"on three quizzes in Queston 8a
Answer:Average (x)= 92
b.William needs 97 as his third score to get as average of 90
Step-by-step explanation:
a.
The Average ( x) of the scores can solved using the Formulae
Average ( x)= Sum of scores / Number of Scores
Average ( x) = (Score 1 + Score 2 + Score 3) /3
Average (x)= (91, 92, and 93 )/3=276/3 = 92
b) Average ( x) of the scores = Sum of scores/ Number of Scores
Now let Score be represented as S such that
Average (x) = (S 1 + S 2 + S3 )/ 3
90 = 85+ 88+ S/ 3
90 x 3= 85+ 88 + S
270=173+ S
S= 270- 173
S=97
William needs 97 as his third score to get as average of 90
L x b x h
1 1/2 x 3/12 x 2/12
13 1/8. I THINK
Answer:
225 cm²
Step-by-step explanation:
dilatation factor = 3 , then
area factor = 3² = 9
the area of the dilated polygon is then 9 times the area of the original so
area of dilated polygon = 9 × 25 = 225 cm²
The answer is b. you just multiply the 2 sides of both rectangles to get (6x^2+20x+24) for the bigger rectangle and (x^2-4x+3) for the smaller one so then you substract the bigger one from the smaller one to get the answer
