Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

m =\frac{y_2 - y_1}{x_2 - x_1}

Pick any two corresponding points from the table

So, we have:

(x_1,y_1) = (8,1.21)

(x_2,y_2) = (12,1.63)

So:

m =\frac{y_2 - y_1}{x_2 - x_1}

m =\frac{1.63 - 1.21}{12 - 8}

m =\frac{0.42}{4}

m =0.105

The linear equation is then calculated using:

y = m(x - x_1) + y_1

This gives:

y = 0.105 * (x - 8) + 1.21

Open bracket

y = 0.105x - 0.84 + 1.21

y = 0.105x + 0.37

To get the length closest to 4.2lb,

we set y = 4.2

Then solve for x

So, we have:

y = 0.105x + 0.37

4.2 = 0.105x + 0.37

Collect like terms

0.105x= 4.2 - 0.37

0.105x= 3.83

Solve for x

x= 3.83/0.105

x\approx 36.5

PLEASE ANSWER + BRAINLIEST!!
GuDViN [60]
The answer would be B. 4m - 24n + 3.

To solve this, you line up each integer under the proper area. Simply move the positive 4 to the end of the bottom polynomial. Then solve.

17m - 13m = 4m
-12n - 12n = -24n
-1 + 4 = 3
Thus giving you an answer of 4m - 24n + 3 or B.

I hope this helps!

A rectangular board measures 126 cm by 90 cm it can be divided into squares of equal size. Find the least number of squares the
Nat2105 [25]
A square has the same width and height, so find the gcd of 90 and 126. Here are there factors:
90:1,2,3,5,9,10,15,18,30,45,90
126:2,3,6, 7,9,14,18,21,42,63,126
18 is the largest in both so the number of squares will be
90/18 * 126/18
= 5*7 = 35
