The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = side x side

Given  that Vince wants to make a square patio in his yard and has enough concrete to pave an area of 378 square feet

The parameters given are;

The Area of the square patio = 378 square feet

Lets 's' be the side of the square;

Therefore, the dimensions of the sides of a patio that has an area of 378 ft.² is ;

s² = 378

Take square root on both sides

Therefore, s = √378

s = √(9 × 42)

s = 3·√42 ft

Answer:

length is 28,breadth is 29

Step-by-step explanation:

firstly we need to know the definition of consecutive integers:-Consecutive integers are those numbers that follow each other . They follow in a sequence or in order.

let the length and breadth be represented by n and n+1

since we are given in perimeter

perimeter of a rectangle =2(length+breadth)

114=2(n+n+1)

114=2n+2n+2

114=4n+2

114-2=4n

The probability that the average person has a time faster than Usain Bolt’s record of 9.58 seconds

P(x>9.58)=1

This is further explained below.

Mean[tex](\mu)[/tex]=14 seconds

Standard deviation[tex](\sigma)[/tex]=0.8 seconds

To determine the likelihood that the average individual will beat Usain Bolt's record of 9.58

To express the statement "the probability that the average person has a time faster than Usain Bolt’s record of 9.58 seconds" in a mathematical equation we have:

[tex]&P(x > 9.58)=P\left(\frac{x-\mu}{\sigma} > \frac{9.58-14}{0.8}\right) \\\\&P(x > 9.58)=P\left(z > -\frac{4.42}{0.8}\right) \\\\ &P(x > 9.58)=P(z > -5.525)[/tex]

P(x>9.58)=1

Note: we would make use of the normal table in reading z>-5.525

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.

Answer

When x = 12, y = 180

Explanation

We are told that y varies directly as x, which can be written as

y ∝ x

Introducing the constant of variation, k, we have

y ∝ x

y = kx

We can then solve for k knowing that

y = 90 when x = 6

y = kx

90 = (k) (6)

90 = 6k

Divide both sides by 6

(90/6) = (6k/6)

15 = k

k = 15

We can then write the relationship between y and x as

y = kx

y = 15x

when x = 12, y = ?

y = 15x

y = 15 (12) = 180

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:

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.

Considering the definition of parallel and perpendicular line, you get:

A linear equation o line can be expressed in the form y = mx + b

where

Parallel lines are two lines that are always at the same distance from each other.

Two lines are parallel if they have the same slope and different y-intercepts.

Perpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.

The line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.

If you multiply the slopes of two perpendicular lines, you get –1, the slope perpendicular line can be calculated as:

5/8× slope perpendicular line= -1

slope perpendicular line= (-1)÷ 5/8

slope perpendicular line= -8/5

So, the perpendicular line has a form of: y= -8/5x + b

The line passes through the point (8, 4). Replacing in the expression for perpendicular line:

4= -8/5×8 + b

4= -64/5 + b

4 + 64/5= b

84/5= b

Finally, the equation of perpendicular line is y= -8/5x + 84/5.

In this case, the line is y= 5/8x -4, with a value of slope m of 5/8 and ordinate to the origin b of -4.

If two lines are parallel if they have the same slope, the parallel line has a slope of 5/8 and has a form of: y= 5/8x + b

The line passes through the point (8, 4). Replacing in the expression for parallel line:

4= 5/8×8 + b

4= 5 + b

4 -5 = b

-1 = b

Finally, the equation of parallel line is y= 5/8x - 1

The given statement can be written as an algebraic expression as: 2/(x + 2).

A mathematical statement that expresses phrases or words using numbers, variables, and operation signs can be referred to as an algebraic expression.

To translates a given statement in to algebraic expression, we can use "x" as a variable to represent the unknown number in the given word problem.

For example, the number that is added to 2, in the above given scenario, can be represented as "x" in order to translate the given statement into an algebraic expression.

The word "sum" will be represented with the operation sign, "+". Therefore, "the sum of 2 and a number" will be translated as an algebraic expression as, (x + 2).

Therefore, the whole statement, "2 divided by the sum of 2 and a number" will then be expressed in algebraic expression as: 2/(x + 2).

In conclusion, the statement, "2 divided by the sum of 2 and a number", can be written as an algebraic expression as: 2/(x + 2).

The value of the function (f + g)(x) at x = - 5 will be 26.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The functions are given below.

​f(x) = x + 1 and ​g(x) = x² - x

The function (f + g)(x) will be given as,

(f + g)(x) = f(x) + g(x)

(f + g)(x) = x + 1 + x² - x

(f + g)(x) = x² + 1

The value of the function (f + g)(x) at x = - 5 will be given as,

(f + g)(-5) = (-5)² + 1

(f + g)(-5) = 25 + 1

(f + g)(-5) = 26

Step-by-step explanation:

If James bought a cake that weighs 3 1/4 pounds, the number of ounces weighed is 52 ounces.

16 ounces = 1 pound

1 gallon= 8 pints

Since James bought a cake that weighs 3 1/4 pounds, the number of ounces that the cake weighs will be:

= 16 × 3 1/4

= 52 ounces.

Since the tap dispenses 0.15 gallons of water every second, the number of pints of water that is dispensed after 20 seconds will be:

= 0.15 × 8 × 20.

= 24 pints.
