Answer:
0.83 mi/min
Step-by-step explanation:
Start with 80 km/hr. Convert this to the units miles/hr:
(80 km/hr)(1 mile/1.6 km) = 50 miles/hr
Next, apply the equality 60 min / 1 hr = 1 to 50 miles/hr:
50 miles. 1 hr
------------- * ------------ = 5/6 mi/min, or 0.83 mi/min
hr 60 min
Answer:
<h3>Given</h3>
- g varies jointly with h and j
- g = 4 when h = 1/2, j = 1/3
<h3>To find</h3>
- Value of g when h = 2 and j = 3
<h3>Joint variation:</h3>
- g = khj, where k- coefficient
Use given values of h and j, and find the value of k:
- 4 = k*(1/2)(1/3)
- 4 = (1/6)k
- k = 4*6
- k = 24
The equation is now:
Find the value of g when h is 2 and j is 3:
<u>Correct choice</u> is D
Answer:
x5
Step-by-step explanation:
The answer is A for this problem
We see we can factor out the 3
(3)(x^2-8x-10)
what multiplies to -10 and adds to -8
2+5=7
1+10=11
nope
factored form is
3(x^2-8x-10)
