Answer: The girls walked
miles.
Step-by-step explanation:
Given: Distance from home to school =
mile
Distance from school to store =
mile
Distance from store to home =
miles
Total distance = ![\dfrac6{10}+\dfrac38+\dfrac25](https://tex.z-dn.net/?f=%5Cdfrac6%7B10%7D%2B%5Cdfrac38%2B%5Cdfrac25)
=
[L.C.M.(10,8,5)=40]
=
=
=
miles
Hence, The girls walked
miles.
Answer: Barbarino's rentals has a better deal.
She has to drive 887.5 miles to spend the same amount at either company.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em>Mr.kotters rentals (A)
</em>
- <em>$99 PER WEEK
</em>
- <em>$0.11per mile over 100 miles
</em>
<em>Barbarino's rentals (B)
</em>
- <em>$75 per week
</em>
- <em>$0.15 per mile over 150 miles
</em>
For "A"
Cost = 0.11 (432-100) + 99 = $135.52
For "B"
Cost= 0.15 (432-150) +75 = $117.3
Barbarino's rentals has a better deal, since $117.3(B) < $135.52 (A)
To find how many miles would Glenna drive before she would be spending the same amount at either company:
A =B
0.11 (M-100) + 99 =0.15 (M-150) +75 = $117.3
Solving for M (miles)
0.11 M -11+99 = 0.15 M -22.5+75
-11 +99 +22.5 -75 =0.15M -0.11 M
35.5 = 0.04M
35.5/0.04 = M
887.5 =M
She has to drive 887.5 miles to spend the same amount at either company.
Answer:
b
Step-by-step explanation:its is b because in three days they earn 48 dollars in 6 days the earn 96 dollars in 7 days they earn 112 dollars so it is b
The spring stretch by 80cm if a spring constant 0.5 m has a force of 40 newtons applied to it
<h3>How to calculate the force acting on string?</h3>
According to Hookes law
F = ke
where
F is the applied force = 40N
k is the spring constant
e is the extension = 0.5
Substitute
40 = 0.5e
e = 40/0.5
e = 80cm
Hence the spring stretch by 80cm if a spring constant 0.5 m has a force of 40 newtons applied to it
