Answers

Answer:

Step-by-step explanation:

I bought 5 crates of apples

Each crate contains 10 apples

I want to exhibit the appleonin 5 shelves

Therefore the apples on each shelve can be calculated as follows

Total apples= 50

= 50/5

= 10

Hence there would be 10 apples on each shelf

According to Pythagoras' Theorem, in a right-angled triangle,

(side 1)² +(side 2)²= (hypotenuse)²

Applying Pythagoras' Theorem,

x² +18²= 30²

x² +324= 900

x²= 900 -324 (-324 on both sides)

Step-by-step explanation:

A farmer filled two cylindrical silos with wheat. The wheat in both silos has a density of 50 pounds per cubic foot. He had the wheat tested for protein content.

• The larger silo has a radius of 5 feet, a height of 10 feet, and the wheat is 12% protein.

• The smaller silo has a radius of 6 feet, a height of 6 feet, and the wheat is 15% protein.

The farmer states that the wheat in each silo contains over 5000 pounds of protein. Which of these is a correct evaluation of the farmer’s statement?

A.) He is correct about the protein content in both silos.

B.) He is incorrect about the protein content in both silos.

C.) He is correct about the protein content in the larger silo but incorrect about the protein content in the smaller silo.

D.) He is incorrect about the protein content in the larger silo but correct about the protein content in the smaller silo.

Answers

Answer:

Step-by-step explanation:

volume of a cylinder = nr^2h

n = 3.14

r = radius

Volume of bigger cylinder = 3.14 x 5^2 x 10 = 785

total density = 50 x 785 = 39250

Protein content = 0.12 x 39250 = 4710

Smaller cylinder = 3.14 x 6^2 x 6 = 678.24

678.24 x 50 = 33912

33912 x 0.15 = 5086

The Bernal leadership class is going to sell spirit t-shirts for students and needs to order a color that most students would like to wear, so they ask every fourth student entering the school about their favorite t-shirt color to make a decision about all Bernal students.

Answers

Biased, because some students may not like that color, and thus going off of the most popular opinion is only supporting the most popular color. Adding onto that, not every student even gets to vote since it is only every 4th student.

have x 50 notes and y N100 notes. There
are eight notes altogether and their total
value is N550. How many of each note do
I have

Answers

Answer:

Step-by-step explanation:

You need to use simultaneous equations to solve this problem since there are 2 variables.

1. 50x + 100y = 550 (value of the notes x the number of each note)

2. x + y = 8 (the number of each note added).

3. Multiply the second equation by 50 so that it the x variables are the same in both equations. Thus, 50x + 50y = 400.

4. Subtract 50x + 50y = 400 from 50x + 100y = 550.

5. The subtraction results in 50y = 150.

6. Divide by 50. y = 3, so x must equal 5.

f(x) = x°-9x
g(x) = x2 - 2x-3
Which of the following expressions is equivalent to f(x)/g(x), for x > 3

Answers

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95 miles per hour. The eastbound train travels at 105 miles per hour. How long will it take for the two trains to be 440 miles apart?

Do not do any rounding.

[] hours

Answers

Answer:

2.2 hr

Step-by-step explanation:

Let t = time

95t = distance of westbound train

105t = distance of eastbound train

95t + 105t = 440

200t = 440

t = 2.2 hr.

Al comprar 5kg de arroz y 6kg de frijol se pagaron 132 pesos.Si se compran 6kg de arroz y 7kg de frijol, se pagan 157 pesos. ¿Cuánto cuesta el kilo de frijol?

Answers

Answer:

El kilo de frijol cuesta 7 pesos.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de ecuaciones lineales con las mismas incógnitas, que se relacionan mediante dichas ecuaciones.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

Para el planteo de este problema mediante un sistema de ecuaciones se debe plantear las siguientes variables:

x: precio de 1 kg de arrozy: precio de 1 kg de frijol

Al comprar 5 kg de arroz y 6 kg de frijol se pagaron 132 pesos. Entonces, esto se representa mediante:

5*x + 6*y= 132

Si se compran 6kg de arroz y 7kg de frijol, se pagan 157 pesos. Entonces, matemáticamente se expresa como:

6*x + 7*y= 157

Por lo que el sistema de ecuaciones a resolver es:

[tex]\left \{ {{5*x+6*y=132} \atop {6*x+7*y=157}} \right.[/tex]

Deseas conocer el precio del kilo de frijoles, es decir, que deseas conocer el valor de la variable y.

Resolviendo mediante el método de sustitución (que despejar una de las incógnitas en una de las ecuaciones y sustituir la expresión en la otra), despejamos el valor de la variable x de la primer ecuación:

[tex]x=\frac{132-6*y}{5}[/tex]

Reemplazando esta expresión en la segunda ecuación y resolviendo se obtiene:

[tex]6*\frac{132-6*y}{5}+7*y=157[/tex]

[tex]\frac{6}{5}*(132-6*y)+7*y=157[/tex]

[tex]\frac{6}{5}*132-\frac{6}{5}*6*y+7*y=157[/tex]

[tex]158.4-7.2*y+7*y=157[/tex]

-7.2*y + 7*y= 157 - 158.4

-0.2*y= -1.4

y= -1.4÷ (-0.2)

y= 7

El kilo de frijol cuesta 7 pesos.

Is the statement x={x+1} true for all real numbers? Explain.

Answers

Answer:

Step-by-step explanation:

It is not true for any real number.

Subtract x from both sides to get 0=1, a contradiction.

Answer:

The statement is not true for all real numbers. It is only true for decimal or fractional values of x .

If x is an integer, then the ceiling function returns x when the input is x . But, the flooring function returns x + 1 when the input is x + 1.

Since x does not equal x + 1 when x is an integer, the expressions are not equal when x is an integer.

Write a set of parametric equations for the equation x = 3y - 2 given that t= x + 3

Answers

Answer:

i hope you meant "y" instead of "t" because that would make so much more sense. all you have to do with this is replace "y" in the equation with "x + 3" (this makes the equation x = 3[x + 3] - 2). now, you multiply and combine the like-terms (making x = 3x + 7). you now continue by subtracting 3x from both sides of the equation to make -2x = 7 and dividing to make x = -3.5

Step-by-step explanation:

x = 3(x + 3) - 2

x = 3x + 9 - 2

x = 3x + 7

-2x = 7

x = -3.5
