A counter top is 18 feet long and 3 feet wide. What is the area of the counter top in square meters? Use the conversion 1 foot =

podryga [215]

Answer:

Area of the counter top is $5.02\ m^2$ .

Step-by-step explanation:

Given:

Length of the Counter top = 18 feet

Width of the counter top = 3 feet

We need to find the area of the counter top is square meter;

Solution:

Now we need to find the area of the counter top is square meter.

But given data is in feet so we will first convert feet into meters.

1 foot = 0.305 meter.

So 18 feet = Number of meters in 18 feet.

By Using Unitary method we get;

Number of meters in 18 feet = $18\times 0.305 = 5.49\ m$

Length of the Counter top = 5.49 m

Also 3 feet = Number of meters in 3 feet.

Again Using Unitary method we get;

Number of meters in 3 feet = $3\times 0.305 = 0.915\ m$

Width of the counter top = 0.915 m

Now we know that;

Area of the counter top can be calculated by multiplying Length of the counter top with width of the counter top.

framing in equation form we get;

Area of the counter top = $5.49\times 0.915 = 5.0233\ m^2$

Rounding up to 2 decimals we get;

Area of the counter top = $5.02\ m^2$

Hence Area of the counter top is $5.02\ m^2$ .

-3x - y = 15<br> y = -8x<br> (x, y) = (0<br> )<br> 9,0

Nataly [62]

<h3>The solution is (x, y) = (3, -24)</h3>

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

-3x - y = 15 -------- eqn 1

y = -8x ------ eqn 2

We have to find solution of (x, y)

We can solve by substitution method

<em><u>Substitute eqn 2 in eqn 1</u></em>

-3x - (-8x) = 15

-3x + 8x = 15

5x = 15

Divide both sides by 5

Substitute x = 3 in eqn 2

y = -8(3)

Thus solution is (x, y) = (3, -24)

At an annual effective interest rate of i, the following are all equal:

Kipish [7]

Answer:

PV = 1414.213562

Step-by-step explanation:

Find:

PV = 8,000*V^(t+3)

Solution:

- Split the the exponent of V into t and 3:

PV = 8,000*V^t*V^3

- We will calculate the V^t and V^3 from information given.

- The present value of 10,000 at the end of 6 years and immediate value of $5,000. De-crypt this statement we have:

10,000*V^6 = 5,000

V^6 = 5,000/10,000

V^6 = 0.5

V^3 = sqrt(0.5)

- Using 2 and 3, De-crypt:

6000*V^t + 56,000*V^2t = 5000

Solving the quadratic in V^t:

V^t = 0.25

- Hence, we have the present value as:

PV = 8,000*V^t*V^3

PV = 8,000*sqrt(0.5)*0.25

PV = 1414.213562

Select the equation in point-slope form for the line that passes through the point (1, –1) and has a slope of 4.

Dvinal [7]

Answer:

$\large \boxed{y + 1 = 4(x - 1)}$

Step-by-step explanation:

The point-slope formula for a straight line is

y - y₁= m(x - x₁)

x₁ = 1; y₁ = -1; m = 4

Substitute the values

$\begin{array}{rcl}y - (-1) & = & 4(x - 1)\\y + 1 & = & 4(x - 1)\\\end{array}\\\text{The equation for the line in point-slope form is $\large \boxed{\mathbf{y + 1 = 4(x - 1)}}$}$

The figure shows the graph of the equation with slope 4 passing through (1, -1).
