Step-by-step explanation:

S + R represents the total trips done by these trucks.

Volume is defined as the amount of space occupied by an object that is bound by a boundary. It must be noted that the volume is a mathematical term that is only applicable to 3D (three-dimensional) objects or spaces. As such, the units commonly used for volume are cubic units, that is, m3, cm3, in3, etc.

Two dump trucks hauling rock to a construction site is given by the expression. xS + yR

S +R

Truck 1 can haul x cubic yards

Truck 2 can haul y cubic yards.

Truck 1 makes P trips to the construction site, while truck 2 makes R trips.

Hence the trips made by truck 1 and truck 2 should be the addition of the trips made by the trucks individually.

So the total trips is represented by S + R

Therefore, S + R represents the total trips done by these trucks.

Answer: p=-10

Step-by-step explanation:

0.5p=p+5

-p     -p

-0.5p=5

Multiply by -0.5 on each side

p=-10

The value of p in 0.5p=p+5 is -10.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

0.5p=p+5

Now, solving for p

For which p from Right side should be moved to left side

0.5p - p= 5

-0.5p = 5

Now, Divide both side by (-0.5)

-0.5p/ (-0.5)= 5/(-0.5)

p = -10

Hence, the value of p is -10.

The maximum value attained by the sum of the expression is 169 when N is the two-digit number 98.

Let N be a two-digit number with digits a and b. Then, the sum of N and the product of its digits is N + ab, and the sum of N's digits is a + b. Therefore, the expression we want to maximize is:

Substituting N = 10a + b, we get:

To maximize this expression, we want to maximize a and b. Since a and b are digits, they must be between 1 and 9. If we set a = 9 and b = 8, we get:

The value of dimensions of a triangular prism a = 5m, dimension a = 15m and dimension c = 9m.

A prism is a solid form that is enclosed by plane faces on all of its sides. A prism has two different kinds of faces. Bases refer to the identical top and bottom faces. The name "prism" refers to the form of these bases. For instance, a prism is referred to be a triangular prism if its base is triangular.

The faces of a prism that are not the top and bottom are referred to as its lateral faces. The class of parallelograms also includes all the lateral faces, all of which are identical to one another.

To find the dimensions of a, b and c, we first open all  the faces of prism in first figure, than we compare it with second figure, we find that,

Answer:

x = 4\(\sqrt{3}\) , y = 4

Step-by-step explanation:

using the cosine and sine ratios in the right triangle and the exact values

cos30° = \(\frac{\sqrt{3} }{2}\) , sin30° = \(\frac{1}{2}\) , then

cos30° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{x}{8}\) = \(\frac{\sqrt{3} }{2}\) ( cross- multiply )

2x = 8\(\sqrt{3}\) ( divide both sides by 2 )

x = 4\(\sqrt{3}\)

and

sin30° = \(\frac{opposite}{hypotenuse}\) = \(\frac{y}{8}\) = \(\frac{1}{2}\) ( cross- multiply )

2y = 8 ( divide both sides by 2 )

y = 4

Answer:

La fracción del total de páginas iniciales del cuaderno que representan las páginas disponibles restantes es 19/40

Step-by-step explanation:

El número total de páginas en el cuaderno = 40

Número de páginas utilizadas = 2/5 × 40 = 16 páginas

Número de páginas extraídas = 1/8 × 40 = 5 páginas

Número de páginas disponibles = 40 - 16 - 5 = 19 páginas

Fracción del total restante = 19/40

La fracción del total de páginas iniciales del cuaderno que representan las páginas disponibles restantes = 19/40.

The solution to the differential equation xy = y + xe is y = xe/(x - 1)

From the question, we have the following parameters that can be used in our computation:

xy = y + xe

Rewrite as

xy - y = xe

So, we have

y(x - 1) = xe

Divide both sides by x - 1

y = xe/(x - 1)

Hence, the solution to the differential equation is y = xe/(x - 1)

Explanation:

Mike can build a wall in 5 hours. His work rate is:

His son can do the job in 20 hours. The son's work rate is:

Let the time it takes both of them = x hours. Then, their joint rate is:

Therefore:

We solve the equation for x:

It takes them 4 hours to build a wall together.

We can conclude that there are 120 ways to assign 5 people to sit in 5 chairs.

There are a couple of ways to approach this question, but one common method is to use the permutation formula. A permutation is an arrangement of objects in a specific order, and the formula for calculating the number of permutations is:

P(n,r) = n! / (n-r)!

where n is the total number of objects and r is the number of objects being arranged.

In this case, we want to arrange 5 people in 5 chairs, so we can set n = 5 and r = 5. Substituting into the formula, we get:

P(5,5) = 5! / (5-5)! = 5! / 0! = 5 x 4 x 3 x 2 x 1 / 1 = 120

Therefore, there are 120 ways to assign 5 people to sit in 5 chairs.

Another way to think about this problem is to use the multiplication principle, which states that if there are m ways to do one thing and n ways to do another thing, then there are m x n ways to do both things. We can apply this principle by considering each chair in turn and the number of ways that each person can be assigned to it.

For the first chair, there are 5 people who could sit there. For the second chair, there are 4 people left who could sit there. For the third chair, there are 3 people left who could sit there. For the fourth chair, there are 2 people left who could sit there. Finally, for the fifth chair, there is only 1 person left who could sit there.

Using the multiplication principle, we can multiply the number of ways for each chair to get the total number of ways to assign people to chairs. This gives us:

5 x 4 x 3 x 2 x 1 = 120

This is the same answer we got using the permutation formula. Therefore, we can conclude that there are 120 ways to assign 5 people to sit in 5 chairs.

Note that both methods produce the same answer, but they may be more or less efficient depending on the specific problem.

Answer:

18 degrees Fahrenheit

Step-by-step explanation:

Given

\(F = 32 + 1.8C\)

Required

Determine change in F if change in C is 10

A 10 degrees change in C is represented as: C + 10

The equivalent change in F is F + x, where x represents the change in F

So: If \(F = 32 + 1.8C\)

Then

\(F + x = 32 + 1.8(C + 10)\)

Open brackets

\(F + x = 32 + 1.8C + 18\)

Collect Like Terms

\(F + x = 32 + 18+ 1.8C\)

\(F + x = 50+ 1.8C\)

Make x the subject

\(x = 50+ 1.8C - F\)

Recall that: \(F = 32 + 1.8C\)

So:

\(x = 50+ 1.8C - F\) becomes

\(x = 50 + 1.8C - (32 + 1.8C)\)

Open Bracket

\(x = 50 + 1.8C - 32 - 1.8C\)

\(x = 50 - 32+ 1.8C - 1.8C\)

\(x = 50 - 32\)

\(x = 18\)

Hence:

A change of 10 degrees Celsius will bring a change of 18 degrees Fahrenheit

Step-by-step explanation:

Water = 39 pounds

brick dust = 48 pounds

Total mixture = water + brick dust

= 87 pounds

She spills 13 pounds of the mixture while stirring

Remaining mixture = Total mixture - Spillage

= 87 pounds - 13 pounds

= 74 pounds

The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture

Number of bricks made = Remaining mixture / pounds per brick

= 74 pounds / 7 pounds
