Answer:
$120.
Step-by-step explanation:
The amount he sells the tool kit for = 80 + 20% of 80
= 80 + 16
= $96.
Let m be the marked price, then
m - 0.20m = 96
0.8m = 96
m = $120.
3 multiplied by 5 is 15 times 2 is 30 that should be ur answer
Answer:
2m/s²
Step-by-step explanation:
If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:
F∝a
F = ka.
F is the force
a is the object's acceleration
From the expression;
k is the constant of proportionality
When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then
k = 25/5
k = 5Ns²/m
If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above
F = ka
Given F = 10N and k = 5Ns²/m
a = F/k = 10/5
a = 2m/s²
The acceleration of the object will be 2m/s²
Answer:
P(x,y) = -x²+62x
Step-by-step explanation:
if x and y are the numbers, then x+y = 62. We put y in function of x; y = 62-x. The product of x and y can, therefore, be represented as a function over the variable x <em>only</em>
P(x,y) = x*y = x*(62-x) = -x²+62x
This function represents the result of the product of x with y.
I hope that works for you!
Answer:
10
Step-by-step explanation:
20÷2=10 because It takes two to make one.
