The answers are following

sol1 y = x-1

sol2 y= x+ 7

sol4 y = x+4

Step-by-step explanation:

Solution 1

Here we are going put the point in the given equation ( given in the options)

If the each point satisfies any equation, that will be the relationship between x and y.

Given points are (-3,-4) , (2,1) , (5,4)

Let us take the option C as y = x -1

-4 = -3-1

1 = 2-1

4=5-1

Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.

Similarly, option B is the answer of Solution 2

Each point satisfies the equation y = x +7

Solution 4

y = x +4

You are requested to check the options of Q3 once.

Upon completion of an experiment a student realizes that the technique used for measuring the length and width of a rectangle ha
eduard

Answer:

809.4cm²

Step-by-step explanation:

Given the following :

Systematic error = 3.8cm (The measured length is always more than the actual length.)

Most probable dimension :

Width = 85.7 cm

Length = 123.5 cm

Hence most probable area of Rectangle :

Area = Length × Width

Area = 85.7cm × 123.5cm = 10583.95 cm²

Dimension due to Systematic error :

Length = (85.7cm + 3.8cm) = 89.5cm

Width = (123.5cm + 3.8cm) = 127.3cm

Area = Length × width

Area = ( 89.5cm × 127.3) = 11393.35cm²

Systematic error of the area :

value of area with Systematic error - Probable value of area :

11393.35cm² - 10583.95 cm² = 809.4cm²

If tile costs $8.50 per square foot, how much does it cost per inch?
Sphinxa [80]

Answer:

$0.06 per square inch

Step-by-step explanation:

The question should be:

<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>

<em />

To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".

We know 1 feet = 12 inches

Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.

Thus, we will have:

\frac{8.5}{12*12}

We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:

\frac{8.5}{12*12}=0.06

So, tile costs $0.06 per square inch
