Answer:
B
Step-by-step explanation:
The ratios are 2:1
In the table it shows 4:2, 8:x, y:6, 20:z
To find if the ratios are equivalent we would need to plug in
Once plugging in answer B we get 4:2, 8:4, 12:6, 20:10 which would all equate to 2:1
Answer:
No solutions
Step-by-step explanation:
Solve for x the system of two inequalities:
First, solve each inequality separately:
1.
2.
Now, we get
and
There are no common values for x, for which both inequalities hold, so the system of two inequalities has no solutions.
X - the number of plants in 8 in pots
y - the number of plants in 10 in pots
4 plants in 8 in pots and 2 in 10 in pots.
Answer:
the number of miles is 14,722
Step-by-step explanation:
The computation of the number of miles drive last year is shown below:
= Total cost ÷ cost per mile
= $1,560 + $3,740 ÷ $0.36 per mile
= $5,300 ÷ $0.36 per mile
= 14,722 miles
Hence, the number of miles is 14,722
The area under the speed curve tells you how much distance the vehicle covers.
The distance for first 30 s corresponds to the area of a rectangle with height <em>k</em> m/s and length 30 s, or
(<em>k</em> m/s) (30 s) = 30<em>k</em> m
The distance for the last 20 s corresponds to the area of triangle with height <em>k</em> m/s and length 20 s, or
1/2 (<em>k</em> m/s) (20 s) = 10<em>k</em> m
If the total distance traveled was 1.7 km = 1700 m, then
30<em>k</em> + 10<em>k</em> = 1700
40<em>k</em> = 1700
<em>k</em> = 42.5
