Answer:

Area of the circle = $153.86\,units^2$

Step-by-step explanation:

Area of the Circle= $\pi \times r^2$

For, $r=7 \,units$

As,

$\pi =\dfrac{22}{7} =3.14$

Area is:

$=3.14\times 7 \times 7\\\\=3.14\times 49\\\\=153.86\,units^2$

The area of the circle is : $153.86\,units^2$

The equation 6y = 30 - 8x has solutions of (b, 1) and (a, b).<br> What are the values of a and b?

victus00 [196]

The values of $a$ and $b$ are $a = \frac{3}{2}$ and $b = 3$ , respectively.

In this question we need to solve the linear equation for each point, first for $(x,y) = (b, 1)$ and later for $(x,y) = (a, b)$ .

If we know that $(x,y) = (b, 1)$ , then the value of $b$ is:

$6 = 30-8\cdot b$

$8\cdot b = 24$

$b = 3$

If we know that $(x,y) = (a, b)$ and $b = 3$ , then the value of $a$ is:

$6\cdot b = 30 - 8\cdot a$

$18 = 30-8\cdot a$

$12 = 8\cdot a$

$a = \frac{3}{2}$

The values of $a$ and $b$ are $a = \frac{3}{2}$ and $b = 3$ , respectively.

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$

Slope of the first line 5x + 3y = 15 after calculation is

the slope is $y= \frac{5}{-3x} +5\\\\\frac{5}{-3}$

this means that the line is perpendicular to the given line

Slope of the second line 3x + 5y = 15 after calculation is

$y= \frac{3}{-5x} +15\\\\\frac{3}{-5}$

This means that the line is not perpendicular and not parallel

Slope of the Third line -3x + 5y = 15 can be calculated as

$y= \frac{3}{5x} +15\\\\\frac{3}{5}$

This means that the line is parallel to the above line.

Slope of the first line 3x + 5y = 15 after calculation is

$y= \frac{-3}{5x} +3\\\\\frac{-3}{5}$

This means that the line is not parallel or perpendicular to the line

1. Leo made a container to store his camping gear. The container is in the shape of a rectangular prism. The container has mater

AleksandrR [38]

<span>(a) What is the capacity of the container?
Volume = length * width * height
V = 4ft * 2ft * 3ft
V = 24 ft</span>³
<span>
(b) How much material was used to make the container?
Surface area = sum of 6 faces of the prism
4 ft x 3 ft = 12 ft</span>² → 12 ft² x 2 = 24 ft²
4 ft x 2 ft = 8 ft² → 8 ft² x 2 = 16 ft²
2 ft x 3 ft = 6 ft² → 6 ft² x 2 = 12 ft²
<span>
Surface area = 24 ft</span>² + 16 ft² + 12 ft² = 52 ft²
