Answer:
B, D and E.
Step-by-step explanation:
These numbers are irrational because their exact values can only be represented by those square roots. If you try to "do the maths", it will be something like:
\sqrt{15} = 3.872983...\\
\sqrt{57} = 7.549834...\\
\sqrt{8} = 2.828427...

write 1.359 x 10^5 in standard form
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.

Which of the following equations have no solution? Check all that apply.
6x + 1 = 3(2x – 4)
2 – 5x = 7x – 12
4(3 – x) = 2(6 – 2x)
5(x + 2) = 2(x – 4)
–4(x + 3) = 4(–x – 1)
Answer:
–4(x + 3) = 4(–x – 1) and 6x + 1 = 3(2x – 4)
Step-by-step explanation:
Answer:
1 ans 5
Step-by-step explanation:
no solution –––
6x + 1 = 3(2x - 4)
6x + 1 = 6x - 4
6x - 6x + 1 = 6x - 6x - 4
1 ≠ -4
one solution
2 - 5x = 7x - 12
2 -5x + 5x = 7x + 5x - 12
2 = 12x - 12
2 + 12 = 12x - 12 + 12
14 = 12x
x = 14/12
infinite solutions
4(3 - x) = 2(6 - 2x)
12 - 4x = 12 - 4x
12 - 12 - 4x + 4x = 12 - 12 - 4x + 4x
0 + 0 = 0 + 0
0 = 0
one solution
5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
5x - 5x + 10 + 8 = 2x - 5x - 8 + 8
18 = -3x
x = -6
no solution –––
-4(x + 3) = 4(-x - 1)
-4x + 4x - 12 = -4x + 4x - 4
-12 ≠ -4

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

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

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?
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.

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
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
See attachment for an illustration of rotation symmetry of a triangle.

retail store purchases a couch for $600 and marks it up 25% to sell. How much is the retailer asking for the couch?
Answer:

To find the new price, multiply the original price by 1.25, since there is a 25% increase in the price:
600(1.25)
= 750

3/2+1/2x=2x
3/2+1/2=2x
2=2x
1=x
Answer:
2 = x
Step-by-step explanation:
3/2 + 1/2 times x = 2x
x by itself = 1x
Subtract 1x
3/2 + 1/2 times 1x - 1x = 2x -1x =
3/2 + 1/2 = 1x
3/2 + 1/2 = 4/2 = 2
2 = 1x
1x/1 = x
2/1 = 2
2 = x

Write the equation of a quadratic with x-intercepts at (-1,0) and (4,0)
Answer:
y = x² - 3x - 4
Step-by-step explanation:
Given that the x- intercepts are x = - 1 and x = 4, then the corresponding factors are
(x + 1) and (x - 4) and the quadratic is the product of the factors, that is
y = (x + 1)(x - 4) ← expand using FOIL
y = x² - 3x - 4
