Answer:
About 384.3 feet
Step-by-step explanation:
The formula for that is given by,
Where,
S is the speed of the car
d is the distance of skid
f is the drag factor for the road surface
n is breaking efficiency as percentage
Putting the values we get,
feet
So the length of skid marks would be 384.3 feet.
Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80
Answer:
Step-by-step explanation:
If breadth =x
length =x+2
Area =length *breadth
Area =x(x+2)=80
X^2+2x-80=0
X^2 +10x - 8x - 80=0
X(x+10)- 8(x+10)=0
(X-8)(x+10)=0
X=8 or x=-10
X=8(since breadth cannot be a negative value x cannot be negative)
Answer:
Number of birds = 13
Explanation:
An animal shelter spends $1.50 per day to care for each bird and $3.50 per day to care for each cat.
Let the number of bird be 'a' and number of cat be 'b'.
Total money spent = 103.5
1.5 a + 3.5 b = 103.5 ------------------------equation 1
Total number of birds and cats = 37
a + b = 37 ------------------------equation 2
1.5 x equation 2
1.5 a + 1.5 b = 55.5 ------------------equation 3
equation 1 - equation 3
2 b = 103.5 - 55.5 = 48
b = 24
Substituting in equation 2
a = 37 - 24 = 13
Number of birds = 13, Number of cats = 24.
There should be multiple answers here.
15 + 14 + 30 = 59
Or
16 + 11 + 32 = 59
Or
17 + 8 + 34 = 59
I’m sure there’s more but these are just the few I did.
