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.
Answer:
amount invested in the account that earns 10% interest = Rs 3500
amount invested in the account that earns 8% interest =Rs 5500
Step-by-step explanation:
Two equations can be derived from the question
x + y = 9000 equation 1
0.08x + 0.1y = 790 equation 2
x = amount invested in the account that earns 8% interest
y = amount invested in the account that earns 10% interest
multiply equation 1 by 0.08
0.08x + 0.08y = 720 equation 3
subtract equation 3 from 2
0.02y = 70
divide both sides of the equation by 0.02
y = 70 / 0.02
y = 3500
Substitute for y in equation 1
x + 3500 = 9000
x = 9000 - 3500 = 5500
Answer:
-3
Step-by-step explanation:
7x + y^2
subsitute
= 7x=7x-4= -28
=y^2=5^2= 25
-28 + 25= -3
75%
135x100= 13500
13500/180=75
The statement is a mathematical statement, and the equation that shows the statement is y = 4m - 3
<h3>How to determine the equation?</h3>
The product of 4 and m is represented as:
4 * m
Evaluate
4 * m = 4m
3 less than this product is represented as:
4 * m - 3 = 4m - 3
Let the result of the equation be represented with y.
So, we have:
y = 4m - 3
Hence, the equation that shows the statement is y = 4m - 3
