On solving the linear equation, There are in total 24 unshaded squares and 16 shaded squares.

<h3>What is a linear equation?</h3>

Ax+By=C is the usual form for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. When an equation is provided in this format, finding both intercepts is rather simple (x and y).

squares, where x= number of squares

2x = shaded squares

Number of unshaded squares = 3x.

This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)

Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.

2x+3x = 40

5x = 40

x = 40/5

x = 8

There are 3×8 = 24 unshaded squares

8×2 = 16 shaded squares in all.

Therefore, you may shade in 8 squares whatever you choose.

In a circle, area and circumference can be found using the formulas A=(pi)r^2 and C=2(pi)r, respectively, Write a formula for A
AURORKA [14]

Answer:

A = \dfrac{C^2}{4\pi}

Step-by-step explanation:

Given that

Area of a circle A=\pi r^2

Circumference of the circle C = 2 \pi r

Let us re-write the equation of area of circle:

A=\pi r^2

A = \pi \times r \times r

Multiplying and dividing with 2:

A = \dfrac{2\pi r}{2} \times r\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C}{2} \times r\\\text{Multiplying and dividing by } 2\pi:\\\Rightarrow A = \dfrac{C}{2} \times \dfrac{2\pi r}{2\pi}\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C \times C}{4 \pi}\\\Rightarrow A = \dfrac{C^2}{4 \pi}

Hence, <em>A</em> in terms of <em>C</em> can be represented as:

A = \dfrac{C^2}{4\pi}

What is the missing number?
JulsSmile [24]

Answer:

y = 2^{x}

Step-by-step explanation:

Given the above data for x and y.

From the algebraic expression;

y = 2^{x}

We can deduce that the value of y is equal to two (2) raise to the power of x.

When x = 1, y = 2

y = 2^{x}

y = 2^{1}

y = 2

When x = 2, y = 4

y = 2^{x}

y = 2^{2}

y = 4

When x = 3, y = 8

y = 2^{x}

y = 2^{3}

y = 8

The above calculations can be used to determine the other values of y with respect to x.

Use logb^2=.4307 and logb^3 - .6826 to evaluate logb18
katrin2010 [14]

Log b 18 = logb 2 * 3 * 3

When multiplying logs, they are added together so:

logb 2 * 3 * 3 = logb 2 + logb 3 + logb 3

Logb 2 is given as 0.4307 and logb 3 is 0.6826

Now we have 0.4307 + 0.6826 + 0.6826 = 1.7959

Logb 18 = 1.7959
