Answer:

every 10 mL of solution equals 5 cells

Step-by-step explanation:

I'm not sure if this equation is right but I think it's either 200÷40, 205÷50, or 205÷40 I hope this is kinda helpful.

The half life of a radioactive substance is 10 years. If 64 grams are placed in a
geniusboy [140]

Answer:

2 grams

Step-by-step explanation:

50 years is 5 half lives as 1 half life is 10 years.

64 divide 2 = 32-1 half life

32 divide 2 =16-2nd half life

16 divide 2 = 8-3rd half life

8 divide 2 = 4-4th half life

4 divide 2 = 2-5th half life

This means we will have 2 grams left of the radioactive substance after 50 years.

The merry-go-round at the fair rotates 12 times each minute, and children are 15 feet from the center of the wheel when they are
LiRa [457]
Answer: 16.33 feet/s

Explanation:

1) Data:

a) circular motion
b) revolutions: 12 rpm
c) r = 15 feet
d) v = ?

2) Formulae:

angular velocity: ω = number of rpm × 2π / 60 seconds

linear velocity: v = ω × r

3) Solution:

ω = 12 × 2π / 60 s = 0.4π rad / s

v = 0.4π rad / s × 13 feet = 5,2 π feet / s ≈ 5,2 (3.14159) feet / s = 16.33 feet/s.

That is the answer.

This was very hard for me please help thanks.​
AleksAgata [21]

Step-by-step explanation:

m<5 = 60 (<5 & 60deg < are vertical)

m<6 = 120 (<s 5 and 6 are a linear pair)

m<9 = 120 (<s 6 and 9 are vertical)

m<4 = 80 (<s 4 and 80 deg < are vertical)

m<7 = 100 (<7 and 80 deg < are linear pair)

m<10 = 100 (<s 7 and 10 are vertical <s)

m<8 = 60 (<s 5 and 8 are corresp <s)

m<3 = 80 (80 deg <3 are corresp <s)

m<2 = 40 (80 + 60 + m<2 = 180)

m<1 = 60 (<s 1 & 5 are alt int <s)

Dan borrowed $1,250.00 from his brother who is charging him 5% simple interest. If Dan pays his brother back in 18 months, how m
Aleksandr [31]

Given that Dan borrowed $1,250.00 from his brother who is charging him 5% simple interest. Now we have to find the total payment that he needs to payback including interest. Hence we can use simple interest formula

I=PRT

Where P= 1250

R=5% =0.05

T=18 months = 18/12 = 1.5 years

Now plug these values into above formula

I=PRT=1250*0.05*1.5=93.75


So total payment including interest = 1250+93.75=1343.75

Hence final answer is $1343.75.
