Answer:
can you explain
Step-by-step explanation:
You need to do 60 times 8.4 to get how many minutes. And 60 times 8.4 is 504
Answer:
1) x+2x+x+3 = 23
4x+3=23
4x=20
x=5
2) a_ radius × radius × pi = the area
4×4×3= 48
b_ diameter × pi= the circumfrence
8×3 = 24
3) a) 34_10=24
24÷3=8
b) _24_(_48)= 24
4) a) 2x=9_5
2x=4 => x=2
b)X/3 =12
x= 36
5) x. _2.
y. 3_(_2)=5
x. 0
y. 3_0=3
x. 3
y. 3_3=0
i put them here too
Answer:
Step-by-step explanation:
With this being a proportional relationship, the y-intercept MUST be 0.
Thus, the relationship has the form y = C(x) = ($5/movie)x, where x is the number of movies purchased.
To graph this, first plot a dark dot at (0, 0). Then, starting at (0, 0), move your pencil point 1 unit to the right and from this new position 5 units up. Plot a dark dot at (1, 5). Now draw a straight line through (0, 0) to the right through (1, 5).
Answer:
The product of two rational numbers is a rational number
Step-by-step explanation:
I'll quickly recap the proof: a rational number is, by definition, the ratio between two integers. So, there exists four integers m,n,p,q such that
If we multiply the fractions, we have
Now, mp and nq are multiplication of integers, and thus they are integers themselves. So, ab is also a ratio between integer, and thus rational.
