Step-by-step explanation:
Kajal spoke on the phone from 4{:}50 \text { p.m.}4:50 p.m.4, colon, 50, start text, space, p, point, m, point, end text until 6{:}19 \text { p.m.}6:19 p.m.6, colon, 19, start text, space, p, point, m, point, end text
How long did Kajal speak on the phone?
Answer:
1 hour and 29 minutes
Step-by-step explanation:
4:50 pm to 6:00 pm is 1 hour and 10 minutes.
6:00 pm to 6:19 pm is 19 minutes.
1 hour and 10 minutes + 19 minutes = 1 hour and 29 minutes.
Explanation:
Let's find out how long Kajal spoke on the phone.
4:50 + 10 mins = 5:00
5:00 + 60 mins = 6:00
6:00 + 19 mins = 6:19
To find the total time between 4:50 + 6:19, we add the distances.
10 mins + 60 mins + 19 mins = 89 mins
Thus, Kajal spoke on the phone for 89 minutes.

Simplify 4^2 ⋅ 4^8.
A)4^16
B)4^10
C)1^616
D)1^610
You will get 27pts if you answer this!!!
Answer:
4^2 * 4^8 = B)4^10
Step-by-step explanation:
When multiplying numbers with exponents, you will always add the exponents together. Therefore, 2+8=10 which is 4^10. You can also simplify the numbers and multiply them together. For example, 4^2=16 and 4^8=65,536 and when u multiply those numbers you get 1,048,576. The one that matches is 4^10=1,048,576.

A store is having a sale on CDs. Adrian buys five CDs and spends $40. If he decides to go back to the sale, and buy two more CDs, how much will he pay? How much with he pay for eight CDs?
Answer:
If Adrian buys 2 more CDs, he will pay $56.
Adrian will pay $64 for eight CDs.
Step-by-step explanation:
So, we already know that 5 CDs costs $40. That means that we can use this information to figure out how much 1 CD costs.
40 ÷ 5 = $8 per CD
Now that we know that each CD costs $8, we know that if Adrian buys 2 more CDs, then he will pay $16 ($8 x 2) more than his current price.
$40 + $16 = $56.
If Adrian buys 2 more CDs, he will pay $56.
Now, in order to find out how much 8 CDs costs, we just need to divide $8 by 8.
$8 x 8 = $64
Therefore, Adrian will pay $64 for eight CDs.
I hope this helps! :)
Which number is a solution of the inequality 8 – 1/4b ≥ 27
Answer:
-4.7≥b
Step-by-step explanation:
+1/4b
8=27+1/4b
-27
-19=1/4b
1/4
-4.7≥b
Answer:
b ≤ = -76
Step-by-step explanation:
8 – 1/4b ≥ 27
Subtract 8 on both sides
-1/4b ≥ 19
Times -4 on both sides
b ≤ -76

A bacteria culture doubles every 5 hours. Determine the hourly growth rate of the bacteria
culture. Round your answer to the nearest tenth of a percent.
[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]Answer:
14.87% per hour
Step-by-step explanation:
Let's pretend we're starting with one bacteria.
Double of one is two
We're gonna have to use this formula: A = P(1 + x)ⁿ
A = Amount (which is 2)
P = Initial amount (which is 1)
x = percentage per time (hour)
n = amount of time (hours)
So our equation will look like this:
2 = 1(1 + x)⁵
First, we need to root both sides to isolate (1 + x)
[tex]\sqrt[5]{2} = \sqrt[5]{(1+x)}[/tex]
[tex]\sqrt[5]{2} = 1 +x[/tex]
Then subtract both sides by 1
[tex]\sqrt[5]{2}-1 = 1 +x - 1[/tex]
[tex]x=\sqrt[5]{2}-1[/tex]
[tex]\sqrt[5]{2} = 1.148698355[/tex]
1.148698355 - 1 = 0.148698355
x = 0.148698355

* sqrt = Square Root
Select one:
a.
whole numbers
b.
irrational numbers
c.

d.
rational numbers
Answer:
b.
Step-by-step explanation:
30×0.5×63 = 945
this is not a square number. therefore, the sqrt(945) is a number of infinite digit positions after the decimal point without repeating pattern.
so, it is a prime example of an irrational number.
