Answer:
20
Step-by-step explanation:
Given that: $3.25 in dimes and nickels were distributed among 45 boys.
1 nickel = $0.05
1 dime = $0.10
Let number of coins of dimes be x and the number of coins of nickel be 45-x.
Hence,
0.10x + 0.05(45-x)=3.25
0.10x+2.25-0.05x=3.25
0.05x=3.25-2.25
0.05x=1
x= 1/0.05
x=20
45-x
45-20=25
Answer:
P(E) =5/9
P(F)=P(E) × P(B<Y<R) = 5/54
Step-by-step explanation:
Let E be events that gives no two number on the dice
Probability P(E) = (6 × 5× 4 )/(6×6×6)
P(E) = 130/ 216 = 5/9
Probability P(B<Y<R) = 1/6
Probability P (F) = P(E) × P(B< Y < R)
P(F) = (5/9 )×( 2/6) = 5/ 54
Option(4) is the answer because
In triangle ABC and triangle EDC
Angle ABC=angle CDE=70
And,
Angle BCA= angle DCE. ( vertically opposite angles)
=> triangle ABC is similar to triangle EDC. ( A.A congruence rule)
=> angle A= angle E. (Corresponding parts of similar triangles) or (CPST)
Hope this helps ..!!!
The answer for this is 30
The answer is 4. By using the factor tree method, you can figure out the GCF of each number. This means 4 is the highest number you can mulitply anything by to get both 84 and 36.
