Answer:

2.6

Step-by-step explanation:

Let us assume that the unit of measurement is centimetre (cm)

To obtain the value of A, do the following:

From the diagram above, we can say that the scale is 5 cm to 1 unit since there are 5 lines before a number.

Next, we shall determine the value of 1 cm.

5 cm = 1 unit

Therefore,

1 cm = 1/5 = 0.2 unit

This means that 1 small line is equivalent to 0.2 unit.

Now we shall determine A as follow:

A is exactly 3 lines (3 cm) after number 2.

1 cm = 0.2 unit

3 cm = 3 x 0.2 = 0.6 unit

Now, add 0.6 to 2 to obtain the value of A.

A = 2 + 0.6

A = 2.6

Therefore, A correspond to 2.6

A = 2.6

Therefore, A correspond to 2.6

Given 2 points, write the equation of a line in point-slope form, then convert to slope-interceptform.4) (3, 6) and (8, 6)

ruslelena [56]

First, we have to find the slope

$m=\frac{y2-y1}{x2\text{ - }x1}=\frac{6-6}{8\text{ - }3}=\frac{0}{5}=0$

It is an horizontal line

Point-slope form= = y - 6 = 0 (x - 3)

Slope-intercept = y=mx + b,

let's find b

$\begin{gathered} 6=0(3)+b \\ 6=0+b \\ b=6 \end{gathered}$

y = 0x + 6

y = 6

-1 3/7 x (-3 2/3)=?

xxTIMURxx [149]

I was not sure if the x in your equation was a multiplication sign or a variable
6/7x
-1 multiplied by 3/7x times -2
And when you multiply two negatives it equals a posible so the -2 and -1 turn into a positive

What is the term, coefficient, constant, and factor of 1/2(base1 + base2)h? (Formula used to find area of trapezoid)

vovangra [49]

Answer:

i. Term = $\frac{b_{1}h }{2}$ + $\frac{b_{2}h }{2}$

ii. Coefficient = $\frac{1}{2}$

iii. Constant = $\frac{1}{2}$

iv. Factor = $\frac{h}{2}$

Step-by-step explanation:

A trapezoid is a quadrilateral which has its base parallel to the opposite side. It's area can be determined by;

Area of trapezium = $\frac{1}{2}$ ( $b_{1}$ + $b_{2}$ )h

Where $b_{1}$ is the measure of length of its fist base, $b_{2}$ is the measure of its second base and h is its height.

Considering the given question,

Term = $\frac{b_{1}h }{2}$ + $\frac{b_{2}h }{2}$

Coefficient = $\frac{1}{2}$

Constant = $\frac{1}{2}$

Factor = $\frac{h}{2}$
