Based on the dimensions of the wooden frame and the cost per cubic meter, the cost to Andrea to purchase sand can be calculated to be $71.36

The dimensions of the sandbox to contain the sand is given in feet and yet the cost of the sand is given in cost per cubic meter.

The first thing to do is to convert the dimensions of the sandbox to meters for easier calculations:

Length:

= 4 x 0.3048

= 1.2192 meters

Width:

= 7 x 0.3048

= 2.1336 meters

Depth:

= 3 x 0.3048

= 0.9144 meters

The volume of the sandbox in meters is therefore:

= Length x Width x Depth

= 1.2192 x 2.1336 x 0.9144

= 2.378615113728 meters

= 2.38 cubic meters

The cost of sand to Andrea would be:

= 2.38 x 30 per cubic meter

= $71.36

Solution:

First of all, we must find the 20% of 180 minutes:

180 x 0.20 = 36 minutes.

That means that the bus takes an extra 36 minutes in traffic. So that, if there

was no traffic congestion the total time is:

180-36 = 144 minutes.

So that, we can conclude that the correct answer is:

144 minutes.

Given:

The value of x can be calculated using the general form of the equation of parabola,

Here, (p,q) stands for the vertex of the parabola (20,3).

To find the value of a, consider a coordinate (0,0) and substitute the obtained values in the general equation of parabola.

Now, consider the coordinate of the required distance x of the ball, (x,2).

Substitute the above coordinate, the value of a and the vertex in the equation of parabola.

To solve the square on RHS, take square root on both sides of the equation.

Since, the height of 2 m of ball can be obtained at either side of the vertex.

So the distance between the vertex and the required position is

Then, the other possible position of the ball is,

Hence, the height of the ball will be 2m, either at a distance of 8.5m from origin or 31.5m from the origin.

Slope is 9.

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). A line or a part of a line that connects two locations is said to have a slope, which is a measure of how steep it is. Or. The ratio of how much y grows as x grows by a certain amount is known as a line's slope. A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.

What is Percent ?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

Given:

The 9 litre of 50% acidic liquid.

Required:

What quantity of water should be added to reduce 9 liters of 50% acidic liquid to 30% acidic liquid ?

Explanation:

The solution steps are:

Acidic liquid in 9 liters lotion = (50/100) * 9 = 4.5 liters

Then water = 9 - 4.5 = 4.5 liters

Let 'x' liters be the required quantity of water.

Then :-

[tex]\frac{4.5}{9+x} = \frac{30}{100} = \frac{3}{10}[/tex]

That leads to :-

The equation of the line that represents Saturn Avenue is; y = 4.

The equation of a line can be ascertained using the formula,

y = mx + c

where m is the line's slope and c is just the y - intercept.

m = vertical change/ horizontal change

m = Δy/Δx

m = (y₂ - y₁)/(x₂ - x₁)

In this question, draw a line through the cleaners as well as perpendicular to Planet Drive.

We can discover the slope of the equation by contemplating two points just on line.

Consider the following points: (8, 4) and (16, 4).

Put the value sin slope.

m = (4 - 4)/(16 - 8)

m = 0/8

m = 0

So we got that,

y - intercept = 4

slope = 0  

Put back the values in equation of line.

y = mx + c

y = (0)x + 4

y = 4

Explanation:

Consecutive even integers are things like 2,4,6,8 or 20,22,24,26

Each number is even and the numbers follow one after another.

Let x be the first even number. The next even number is x+2

Based on the fact that "five times the first equals four times the second", we can then write the equation of 5x = 4(x+2)

Let's solve for x.

5x = 4(x+2)

5x = 4x+8

5x-4x = 8

x = 8 is the first even number

x+2 = 8+2 = 10 is the second even number

------------

Check:

5*(first) = 4*(second)

5*8 = 4*10

40 = 40

The answers work out.

Two consecutive even integers such that five times the first equals four times the second are 8 and 10.

Let us suppose the first integer as  a,

Then the second consecutive even integer would be a+2

from the question, it is evitable that,

5a = 4(a+2)

5a = 4a + 8

a = 8

Therefore first even integer is 8.

The second even integer will be,

a+2

8+2 = 10

Cross verifying:

5 × 8 = 40

4 × 10 = 40

Hence the two consecutive even integers such that five times the first equals four times the second are 8 and 10.
