Answer:
7(45)=7(40)+7(5)
Step-by-step explanation:
We need to represent 7(45) using the distributive property to simplify.
We can write 45 as 40+5
So it becomes,
7(45) = 7(40+5)
Distributive property is : a(b+c)=ab+ac
a=7, b = 40 and c = 5
7(40+5)=7(40)+7(5)
So, the correct option is (4).
Answer:26/21
Step-by-step explanation:
Total number of students=21
Number of students that plays basket ball=12
Number of students that plays
baseball=14
Number of students that play neither of the games=5
Probability that a student chosen at random plays basket ball or baseball
=12/21+14/21
26/21
5n - 1 < 24 is the inequality in question. Add 1 to both sides, obtaining:
5n < 25. Divide both sides by 5, obtaining n < 5 (answer)
Multiply $1.99 by 4 for the drinks . Then $1.20 by 4 for the muffins . Add both of the amounts from the drinks and muffins with the tip of $2.30 . Then subtract $30 from the other total . Then you have your answer .
Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V =
r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V =
r²
100 =
(4²)(
)
100 = 16

Divide each side by 16
= 
Cross multiply and solve for h:
4
h = 75
h = 
So, the cone's height is
or approximately 5.97 inches
