Answer:

w = 39

Step-by-step explanation:

3w + 9 + 2w - 24 = 180 , that is

5w - 15 = 180 ( add 15 to both sides )

5w = 195 ( divide both sides by 5 )

w = 39

Answer:

B

Step-by-step explanation:

The number of gray squares for 15 white squares based on the given ratio will be 25.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

Number of white squares = 3

Number of gray squares = 5

The ratio of gray squares to white = 5/3

With maintaining the same ratio,

Let's say the number of gray squares for 15 white squares will be x.

The ratio of gray squares to white will be as x/15

Both ratios must be the same for the same pattern.

x/15 = 5/3

x = (5/3)15 = 25

Hence "On the basis of the specified ratio, there will be 25 gray squares for every 15 white squares.".

Answer:

x = - 10

Step-by-step explanation:

2(x + 3) = x - 4 ← distribute parenthesis on left side

2x + 6 = x - 4 ( subtract x from both sides )

x + 6 = - 4 ( subtract 6 from both sides )

x = - 10

Answer:

-10

Step-by-step explanation:

2(x+3)=x-4

2x+6=x-4

2x-x=(-4)-6

x=-10

Hence the answer is -10

The required volume of the given cylinder is 1005 ft³.

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid.

It is regarded as a prism with a circle as its base in basic geometry.

In several contemporary fields of geometry and topology, a cylinder can alternatively be characterized as an infinitely curved surface.

So, the volume of cylinder formula:

V=πr²h

We have,

Height of 20 ft and diameter of 8 ft.

The radius will be 8/2 = 4 ft.

Now, calculate the volume as follows:

V=πr²h

V=π(4)²20

V=1005.30965

Rounding off: 1005 ft³

Therefore, the required volume of the given cylinder is 1005 ft³.

The graph of the linear equation can be seen at the end, and:

a) f(-4) = 1

b) f(5) = -8

c) f(0) = -3

d) you need to circle the points (-3, 0) and (-10, 7)

Here we have the following linear function:

f(x) = -x - 3

We want to graph that line, but first let's evaluate as it asks in the steps below.

To evaluate the function, we only need to replace the variable x by the correspondent number.

a) f(-4)

Here just replace the variable x by the number -4, you will get:

f(-4) = -(-4) - 3

f(-4) = 4 - 3

f(-4) = 1

b) Here we will do the same thing:

f(5) = -5 - 3

c) f(0) = -0 - 3

f(0) = -3

d) To see which points are in the line, just replace the values of the point in the given equation. If the equation remains true, then the point is on the line.

For example, the first one (-3, 0) will give:

0 = -(-3) - 3

0 = 3 - 3

0 = 0

That equation is true, so the point is on the line.

The point (-10, 7) is also on the line:

7 = -(-10) - 3

7 = 10 - 3

7 = 7

Finally, let's do the graph.

Now you know that (-10, 7) and (-3, 0) are points on the line, you can graph these in the coordinate axis and connect them with a line.

the graph of the linear equation can be seen in the image below.

A system of equations that could be used to determine the number of bottles of soda purchased and the number of bottles of juice purchased are as follows;

Let S = number of bottles of soda.

Let J = number of bottles of juice.

System of Equations:

J = 2 + S  

In order to write a system of linear equations to describe this situation, we would assign variables to the number of bottles of soda and number of bottles of juice respectively, and then translate the word problem into algebraic equation as follows:

Since each bottle of soda has 30 grams of sugar and each bottle of juice has 40 grams of sugar with both of them having a sum total of 430 grams of sugar, we have the following equation:

Functions are another key idea in programming because they let you put a piece of code that performs a specific purpose inside a specified block and then call that code whenever you need it with a single, brief command rather than repeatedly typing the same code.

Code units that are "self contained" and carry out a particular purpose are called functions. Typically, functions "take in," "process," and "return" data and results. Once a function has been developed, it may be utilized countless times.

Answer:

x = 1

Step-by-step explanation:

Given equation,

→ 3(6x - 2) = 2(3x + 3)

Now the value of x will be,

→ 3(6x - 2) = 2(3x + 3)

→ (3 × 6x) - (3 × 2) = (2 × 3x) + (2 × 3)

→ 18x - 6 = 6x + 6

→ 18x - 6 - 6x = 6

→ 12x = 6 + 6

→ 12x = 12

→ x = 12/12

→ [ x = 1 ]

Let's check the value of x,

→ 3(6x - 2) = 2(3x + 3)

→ 3(6(1) - 2) = 2(3(1) + 3)

→ 3(6 - 2) = 2(3 + 3)

→ 3 × 4 = 2 × 6

→ 12 = 12

→ [ LHS = RHS ]

Equation of the line  that passes through the midpoint and is perpendicular to PQ is 2x - y +1 = 0.

One way to describe a perpendicular bisector is as a line segment that cuts through another line segment at a 90 degree angle. Simply said, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle. Measuring a line segment that needs to be bisected will help you discover a perpendicular bisector.

The midway of the measured length can then be determined by dividing it by two. From this center, extend a line at a 90-degree angle. All you need to do to determine the perpendicular bisector of two points is to discover their midpoint and negative reciprocal, then enter these results into the slope-intercept form of the equation for a line.

Here points are P( -4 ,3 ) and Q ( 4,-1)

Mid -point of PQ :

[tex]=(\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )\\\\=(\frac{-4+4}{2} ,\frac{3-1}{2} )\\\\=(0,1)\\[/tex]

Slope of PQ:

[tex]m = \frac{y_{2}{-y_{1} } }{x_{2}{-x_{1} }} \\\\m =\frac{-1-3}{4+4}\\\\ m= \frac{-4}{8} \\\\m = \frac{-1}{2}[/tex]

The slope of the line is Perpendicular to PQ

so, slope 2= -1/m

Answer:

3,398.7 square centimeters.

Step-by-step explanation:

The area of a square is the square of the side length, so the ratio of the areas of the mirrors is equal to the ratio of the side lengths squared. If the ratio of the side lengths of Mirror A to Mirror B is 5:6, then the ratio of the side lengths squared is 5^2:6^2 = 25:36. This means that the ratio of the areas of Mirror B to Mirror C is 25:36.

The ratio of the areas of Mirror B to Mirror C is 25:36, and the ratio of the areas of Mirror B to Mirror C is 16:25, so 25:36 = 16:25. This means that the ratio of the areas of Mirror B to Mirror C is 1:1.5.

The perimeter of Mirror C is 280 centimeters, which means that each side has a length of 280/4 = <<280/4=70>>70 centimeters. The area of Mirror C is the square of this side length, or 70^2 = <<70^2=4900>>4900 square centimeters.

Since the ratio of the areas of Mirror B to Mirror C is 1:1.5, the area of Mirror B is 1.5 times the area of Mirror C, or 1.54900 = <<1.54900=7350>>7350 square centimeters.

The ratio of the side lengths of Mirror A to Mirror B is 5:6, so the side length of Mirror A is 5/670 = <<5/670=58.333>>58.333 centimeters. The area of Mirror A is the square of this side length, or 58.333^2 = <<58.333^2=3398.68>>3398.68 square centimeters. Rounding to the nearest tenth of a centimeter, the area of Mirror A is 3398.7 square centimeters. Answer: {3,398.7}.
