Answer:
A four mile ride would cost $10
Step-by-step explanation:
Let T be the total ride cost
Let M be the amount of miles driven
T = 1.75M + 3
You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles
T = 1.75*(4) + 3
T = 7 + 3
T = 10
Therefore, a four mile ride would cost 10 dollars
Answer:
C. -3
Step-by-step explanation:
Given
Inequality; -5 < x < 0
Required:
A possible value of x
First, the inequality needs to be interpreted
The inequality reads.
-5 < x < 0
This means -5 is less than x and x is also less than 0
In other words, x is greater than -5 and x is less than 0.
With the illustration above, x starts from-4 and ends at -1, i.e. the range of x can be said to be -4 to -1
Possible Values of x: -4,-3,-2,-1
From. Option A through D, only -3 which is option C can be seen in this range.
Hence, -3 is a possible value
Answer/Step-by-step Explanation:
==>Given:
Ratio of cost of 1m polyester fabric to 1m of cotton fabric = 2:7
I.e. if 1m of polyester fabric = £2, then 1m of cotton fabric = £7.
==>Required:
a. Cost of polyester fabric for the following lengths:
i) 6m ii) 8m iii) 9m
Thus, having known that cost of 1m polyester fabric = £2, therefore,
i) 6m polyester fabric = 6×2 = £12
ii) 8m polyester fabric = 8×2 = £16
iii) 9m polyester fabric = 9×2 = £18
b. Cost 8 cotton fabric for the following lengths:
i) 2m ii) 6m iii) 8m iv) 9m
Thus, since 1m of cotton fabric = £7, therefore,
i) 2m cotton fabric = 2×7 = £14
ii) 6m cotton fabric = 6×7 = £42
iii) 8m cotton fabric = 8×7 = £56
iv) 9m cotton fabric = 9×7 = £63
1. 6.25 x 10^0
2. 8.07 x 10^-1
