Answer:
496.631579
Step-by-step explanation:
Make a proportion
We know that a 377.44 over a number must equal 76%
377.44/x=76/100
Cross multiply
76x=37,744
Divide by 76 on both sides
x=496.631579
So, 76% of 496.631579 is 377.44
Hope this helps!
We Know, speed = Distance / Time
Here, Distance = 2748 miles
Time = 6 hours
Substitute their values in to the expression,
Speed = 2748 / 6 = 458 Miles / Hour
So, the speed would be: 458 miles/hour

Answer:
100
Step-by-step explanation:
Given : 
To Find : the value of expression 5a.
Solution :
We are given the value of 'a' i.e. a=20
Now to find the value of given expression 5a
⇒
put a = 20 in the equation
⇒
⇒
⇒
Thus , The value of expression 5a when a = 20 is 100
The rule to represent the aritmathic sequence would be :
A(n) = 130 + (n-1) 13
the height in 13 days would be :
A(n) = 130 + (14-1) 13
A(n) = 130 + 169
= 299 inches
