To find the unit rate do 649.60/116=5.60
($5.60)kg
to find how much for 192 kilograms we have to multiply the unit rate we have to sub in the kg
5.60×192=1075.2
192kg= $1075.20
The answer is x = 7/2 and the decimal form is x= 3.5
Answer:
D(t)=200-40*t
Step-by-step explanation:
He was already travelling for 3 hours, so he travelled 3*40=120miles. Total distance between his house and city A is 120+80=200miles. And he is travelling 40m/h. So I think this function represent his distance from city A depending how much time he was travelling (t).
D(t)=200-40*t
1)
x^-3y^-12 / x^15y^-15
answer is D. last choice
2)
answer is <B'C'D' (third choice)
4)
equivalent 3/9 = 0.33333(3 repeat)
answer is B. second choice
5)
1.7 x 3.5 = 5.95
10^-13 x 10^25 = 10^12
so
= 5.95 x10^12
answer is D. last choice
Answer:
Given the function f(x) = 3x + 1, evaluation of f(a + 1) gives:
C. 3a + 4
Step-by-step explanation:
Given function:
f(x) = 3x + 1
We have to find f(a+1).
For this purpose, we will take x = a+1 and
substitute it in the function f(x) = 3x+1:
f(x) = 3x + 1
f(a+1) = 3(a+1) +1
f(a+1) = 3(a) + 3(1) +1
f(a+1) = 3a+3+1
f(a+1) = 3a + 4
So the function f(a+1) is equal to option C. 3a + 4.
