3(x - 6) = -15 + 3x

Yes no solution show work

Answers

Answer:

see explanation

Step-by-step explanation:

Given

3(x - 6) = - 15 + 3x ← distribute parenthesis on left side

3x - 18 = - 15 + 3x ( add 18 to both sides )

3x = 3 + 3x ( subtract 3x from both sides )

0 = 3 ← not possible

This indicates the equation has no solution

An oblique candle with a volume of 270 cubic centimeters is 18 centimeters tall. The width of the triangular candle base is 5 centimeters, and the width of the slanted candle is 7 centimeters. An oblique triangular prism has a volume of 270 cubic centimeters. The vertical height is 18 centimeters. The width of the triangular bases is 6 centimeters, and the width of the slanted prism is 7 centimeters. What dimensions of the box are required to fit the candle? 5 cm by 6 cm by 18 cm 7 cm by 6 cm by 18 cm 5 cm by 3 cm by 18 cm 7 cm by 3 cm by 18 cm

Answers

Answer:

7 cm by 6 cm by 18 cm

Step-by-step explanation:

Given :

Volume of candle = 270cm³

Height = 18cm

Triangular base = 5cm

Width of candle = 7cm

Volume = Area of base * height

270cm³ = Area of base * 18

Area of base = 270cm³ / 18cm

Area of base = 15 cm²

Using this to find the height of triangular prism :

Area = 1/2 * base * height

15cm² = 1/2 * 5 * height

15cm² = 2.5 *. Height

Height = 6 cm

Hence, the dimension of triangular prism is : 7cm by 6cm by 18cm

Write an equation of a line in slope intercept form that passes through (6,5) 1 poi
and is parallel to y =-X+4 *

Answers

Answer:

y = -x + 11

Step-by-step explanation:

The slope of the line y = -x + 4 is -1.

So the slope of our line is also -1 ( because they are parallel).

First use the point-slope form of the equation of a line:

y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.

Here m = -1 and (x1, y1) = (6, 5).

So we have:

y - 5 = -1(x - 6)

y - 5 = -x + 6

y = -x + 11  <------ Slope intercept form.

Answer:

area = 1539√3 in²

Step-by-step explanation:

three hexagons and one triangle:

each of the three hexagons are composed of 6 equilateral triangles just like the center triangle.

So you have 19 equilateral triangles with each side being 18 inches long.

The height (h) of a triangle will be:

h² = 18² - 9² = 324 - 81 = 243

h = √243

h = 9√3

area of one triangle = 1/2bh = (1/2)(18)(9√3) = 81√3

81√3(19 triangles) = 1539√3 in²

Explain.

Answers

Answer:

Step-by-step explanation:

The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x- axis. At this point, the y- coordinate is zero. The y-intercept is the point at which the graph crosses the y- axis. At this point, the x- coordinate is zero.

the y-intercept is the point where the line crosses over the y-axis (the up and down line)

The 2000 population of a city was 705,000 and was increasing at the rate of 1.51% each year. At that rate, when will the population be 1 million

Answers

Answer:

The population would be 1 million in 2024.

Step-by-step explanation:

In order to find the answer you can use the population growth formula:

A= P*e^rt

A=Population after time=1,000,000

P= Starting population=705,000

e= Euler number that is equal to 2.718

r= rate of growth=0.0151

t= time

Now, you can replace the values on the formula and solve for t:

1,000,000 = 705,000*e^0.0151t

1,000,000/705,000 = e^0.0151t

ln(1,000/705) = ln(e^0.0151t)

ln(1000/705) = 0.0151t

t = [ln(1000/705)]/0.0151

t = 23.14 years

According to this, the answer is that the population would be 1 million in 2024.
