Answer:
if i undertsand the question correctly, there should be 344.
Step-by-step explanation:
add the amount of science books to the amount of history books to get the total :)
181+163 =344
Answer:
Step-by-step explanation:
a = 4
b= 1
c = 2
d =2
Leftside of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 4 *4 + 8 =16 + 8 = 24
No. of P molecules = 2
Right side of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24
No. of P molecules = 2
Answer:
<h2>25 mph</h2>
Step-by-step explanation:
<h3>
Step 1: Convert miles to feet</h3>
First, we need to convert the miles to feet keeping in mind that:
1 mile = 5,280 feet
655 ft 19 sec
5,280 ft 4 min 24 sec
<h3>Step 2: Divide the distance by the time to find the unit rate</h3>
3,447 feet per minute
1,245 feet per minute
<h3>Step 3: Convert minutes to hours</h3>
206,820 feet per hour
74,700 feet per hour
<h3>Step 4: Convert feet to miles</h3>
39.17 miles per hour
14.15 miles per hour
To find how much faster Michael ran, we need one more step.
<h3>Step 5: Subtract smaller amount from larger amount</h3>
39.17 - 14.15 = 25
I'm always happy to help :)
90 degree rotation clockwise : (a,b) --> (b,-a)
so... (24,-15) --> (-15,-24) is a 90 degree clockwise rotation
Answer:
= 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4, thus
= 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
