The actual square root of 2 is 1.414213562373.
I would estimate to 1.4
Answer:
6 miles
Step-by-step explanation:
Info we already know:
$8 to get in the cab.
$0.75 for EACH mile
The word EACH means to multiply
0.75 x 8 = 6 miles
Hope this helps!
If the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.
Given that the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10.
We are required to find the cost of 1 kg of mushrooms and the cost of 1 kg of turnips.
Cost is basically the expenditure that we do in order to buy or produce a product.
Suppose the cost of 1 kg of mushrooms be x and the cost of 1 kg of turnips be y. The equations will be as under:
2x+2.5y=8.55------1
3x+4y=13.10-------2
Equation1 *3 and Equation2 *2.
6x+7.5y=25.65-----3
6x+8y=26.20-------4
Subtract 4 from 3.
6x+7.5y-6x-8y=25.65-26.20
-0.5y=-0.55
y=1.1
Put the value of y in 1.
2x+2.5*1.1=8.55
2x+2.75=8.55
2x=8.55-2.75
2x=5.80
x=2.9
Hence if the cost of 2 kg of mushrooms and 2.5 kg of turnips is £8.55 and the cost of 3 kg of mushrooms and 4 kg of turnips is £13.10, then cost of 1 kg of turnips is £1.1 and cost of 1 kg of mushrooms is £2.9.

Find the equation of the line using the 2 points (2, 1162) and (11, 1900)
First find slope: <u>1900 - 1162</u> = <u>738</u> = 82<u>
</u> 11-2 9
<u>
</u>So the slope is 82. Only one of the 4 choices has a slope of 82, it is the first one. So we don't have to continue to figure out the answer because it has to be A.
y = 82x + 998
