Answer:

B: AC = 4DB

Step-by-step explanation:

Since B is the midpoint of AC, this means that AB≅BC.

Since D is the midpoint of AB, then AD≅DB.

This means that AD is 1/4 of the length of AC, since it is 1/2 of 1/2 of the length (1/2*1/2 = 1/4). DB is the same length, since it is congruent to AD.

This means that AC = 4DB.

2(-4)2=-16
-2(2)4=-16
(3)2=6
-(-4)2=8
(2)4=8
8+8=16+6=22-16=6-16=-10
-10 is the final answer.

A pair of dice is rolled. What is the probability that the sum of the dice rolled is either an 11 or a 5?

zalisa [80]

Rolling an 11:
n(A): 6&5, 5&6
n(A) = 2
Rolling a 5:
n(B): 1&4, 4&1, 3&2, 2&3
n(B) = 4

n(A) + n(B) = 4 + 2 = 6

The correct answer are

Sue interest : 169.6061952

Bill interest: 189.9131472

B. Bill will get more interest then sue

Explain

Sue principal balance p= 2300

Interest for 3 years so t= 3

Interest is compounded yearly n= 1

R= 2.4%

A= 2300(1+2.4/100)^3 = 2300(1+0.024)^3 = 2300 x (1.024)^3 = 2469.6061952

Interest for 3 year is A-p= 2469.6061952 -2300

169.6061952

Bill principle p= 1800

Interest for 3 years t= 3

Interest compounded so n= 1

R= 3.4%

A= 1800(1+3.4/100)^3 = 1800 (1+0.034)^3 = 1800 (1.034)^3 = 1989.9131472

Interest in 3 yrs = 1989.9131472 - 1800 =

189.9131472

For B is below

Hopefully this help you :D

Stuart planted a shrub that was 64 centimeters tall. He measured the shrub regularly and found that it grew 1.8 centimeters each

andreev551 [17]

Answer:

C. 7 weeks.

Step-by-step explanation:

Since the shrub was 64 cm tall at first, take away 64 from 76.6. Now we are left with 12.6. Let's divide 12.6 by 1.8 (that's how many cm it grows per week). When we do this, we are left with 7. This means it took 7 weeks for the shrub to reach 76.6 cm. I hope this helps!
