Answer:
6 laps
Step-by-step explanation:
According to the scenario, calculation of the data are as follows:
Each lap = 0.25 miles
Regan's plan to run= 1.5 miles
So, we can calculate number of laps by using following formula,
Number of laps = Total miles to run ÷ each lap miles
By putting the value, we get
Number of laps = 1.5 miles ÷ 0.25 miles
= 6 laps
So, she should run 6 laps.
Answer:
The change in value is 19,000 altogether and 1900/year
Step-by-step explanation:
Change in value:
initial value - final value
= $26,000 - $7000
= $19,000
Change in value/year:
change in value/time
= $19,000/10
= $1900/year
Hmm
(a+b)^2=(a+b)(a+b)=a^2+2ab+b^2
basically
for
ax^2+bx+c
it is a perfect trinomial when
b=2(√a)(√c)
remember to take both positive and negative roots into consideration
because
(a+b)^2=a^2+2ab+b^2 and
(a-b)^2=a^2-2ab+b^2
see each
first one
-70=2(9)(4)
-70=72
false
second
-90=2(8)(5)
-90=80
false
third
-72=(9)(4)
-72=72
false
but, the last one could be negative
(9x-4)^2 is factor
that is the answer
the answer is 81x^2-72x+16
Answer: I don't know about the formula, but consider the logic below.
Step-by-step explanation:
Martina = 12
Joey = 0
12 x 3 = 36
36 - 3 = 33
If Joey was 21, Martina would be 33.
