Answer 2

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Anna has a nickels and y dimes. She has at most 22 coins worth a minimum of $1.40 combined.

Let x be the number of nickels and y be the number of dimes. Then the equation is given as,

0.05x + 0.10y ≥ 1.40

x + y ≤ 22

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.

A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select ALL conclusions that we can reach this.

A. All sides of the triangle have the same length


B. All angles of the triangle has the same measure

C. All rotations take one half of the triangle to the other half of the triangle

D, it is a right triangle

E. None of the sides of the triangle have the same length

F. None of the angles of the triangle have the same measure

Answers

Answer:

c e f

Step-by-step explanation:

C. All rotations take one half of the triangle to the other half of the triangle

E. None of the sides of the triangle have the same length

F. None of the angles of the triangle have the same measure

If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:

A. All sides of the triangle have the same length

B. All angles of the triangle has the same measure

Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.

This means that:

All sides of the triangle must be the sameAll angles of the triangle must be the sameThe complete length of each side are rotated (not half).

The above points imply that: options (a) and (b) are true

What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)

Answers

Answer:

What do you mean?

Step-by-step explanation:

Answer:

( 5, 0 )

Step-by-step explanation:

 x - 3y = 5

2x +  y = 10  multiply by 3 to eliminate y and solve for x

 x - 3y = 5

6x + 3y = 30  then add

7x          = 35

simplify:

x = 35 / 7

x = 5  

substitute x = 5 back into the eq.2

 2x +  y = 10

2(5) +  y = 10

           y = 10 - 10

           y = 0

 

therefore the answer is ( 5, 0 )

The given number is already in the standard form i.e. 1.359 x 10⁵.

What is standard form?

Standard form refers to any number that may be expressed as a decimal number between 1.0 and 10.0 when multiplied by a power of 10.

When working with extremely big or extremely small numbers, standard form, also known as standard index form, may be quite helpful. It is based on the use of powers of 10 to describe the size of a number.

Scientists may compare the orders of magnitude of various values using standard form, which enables them to understand events and make helpful predictions.

It is given that,


1.359 x 10⁵

We have to convert the given number is in standard form.

Thus, the given number is already in the standard form i.e. 1.359 x 10⁵.

How many quarts of water must be added to 7 qts of a 19% saline solution to obtain a 5% saline solution?

Answers

Answer: quantity of water added = 19.6 quarts

Step-by-step explanation:

Let x= quantity of water added

Then, Quantity of saline in 7 quarts solution  = 19% of 7 = 0.19 (7)=1.33 quarts [to remove % divide number by 100]

When x quarts water is added , the quantity of solution becomes = x+7

Quantity of saline in it= 5% of (x+7)= 0.05(x+7)

Now, quantity of saline remains same, so

[tex]1.33= 0.05(x+7)\\\\\Rightarrow\ 1.33x=0.05x+0.35\\\\\Rightarrow\ 1.33-0.35=0.05x\\\\\Rightarrow\ x=\dfrac{0.98}{0.05}=19.6[/tex]

Hence,  quantity of water added = 19.6 quarts

2. Mr. Jansen needs to order picture frames for his paintings. He has $4,000 to buy 98 frames priced at $42 each. Mr. Jansen says he has enough money because 100x40=4,000. Is his reasoning corrector not? Explain your reasoning.

Answers

his reasoning isn’t correct and the reason for that is because his total is 4,000

and if you do the math that he did (100 x 40 = 4,000) well that maybe true just not for this question

because if he has $4,000 and each picture frame equals $42 he will be able to get 95 picture frames

$42 x 95 = 3,990

which is under the price limit and if he bought one more for example ( $42 x 96 = 4,032) that will be over the limit

Answer:

The reasoning isn't correct

Step-by-step explanation:

This is becuase the given amount for each frame is 42 dollars not 40 like it is listed in the equation. Another reason the reasoning from Jansen is wrong is because he wants to buy 98 frames, not 100 like it was listed in the equation.

Guadalupe fue a la mercería a comprar 15.5 m de encaje blanco que necesita para la clase de costura. Si cada metro cuesta $5.60, ¿cuánto pagó por todo el encaje que necesita?

También pidió 4.75 m de cinta azul que le encargó su mamá. Si el metro cuesta $8.80 y su mamá le dio $40.00, ¿le alcanzará el dinero para comprarla?

¿Le falta o le sobra dinero? ¿Cuánto?​

Answers

Answer:

a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Step-by-step explanation:

a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado ([tex]n[/tex]), medido en metros, y el coste unitario ([tex]c[/tex]), medido en pesos por metro:

[tex]C = c\cdot n[/tex] (Eq. 1)

Si conocemos que [tex]c = 5.60\,\frac{\$}{m}[/tex] y [tex]n = 15.5\,m[/tex], entonces tenemos que:

[tex]C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)[/tex]

[tex]C = \$ \,86.8[/tex]

Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) El coste total de la cinta azul es: ([tex]c = 8.80\,\frac{\$}{m}[/tex], [tex]n = 4.75\,m[/tex])

[tex]C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)[/tex]

[tex]C = \$\,41.8[/tex]

Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.
