Help me please this is so hard

Answer:

Me ha quedado una cuarta parte de la cantidad inicial, es decir, me he gastado tres cuartas partes de la cantidad inicial comprando crustácea importada en la pescadería y marisquería.

Step-by-step explanation:

Asumamos que hacemos la compra en una pescadería y marisquería. Si la razón inicial equivale a 1, gasta inicialmente la mitad de la razón inicial, luego gasta la mitad de la razón resultante. El gasto se entiende como una forma de sustracción mientras que la sucesión como una multiplicación. Por consiguiente, tenemos el siguiente producto:

[tex]c = \left(1-\frac{1}{2} \right)\cdot \left(1-\frac{1}{2} \right)\cdot c_{o}[/tex]

[tex]c = \frac{1}{4}\cdot c_{o}[/tex]

Donde [tex]c_{o}[/tex] es la cantidad inicial.

Me ha quedado una cuarta parte de la cantidad inicial, es decir, me he gastado tres cuartas partes de la cantidad inicial comprando crustácea importada en la pescadería y marisquería.

Answer:

Option D

Step-by-step explanation:

Fractions are considered to be rational numbers because they are decimals that can be written as a fraction and since it's already wrote as a fraction but can be converted back to a decimal it is a rational number. The fraction is considered to be a real number because all rational numbers are real numbers and since we just proved that 5/8 is a rational number it is therefore a real number. Which means your answer is option D or "rational numbers, real numbers."

a diagram is necessary. please provide a diagram.

The surface area of the prism is 456cm² and the volume is 408cm³

A prism is a solid shape that is bound on all its sides by plane faces. There are two types of faces in a prism. The top and bottom faces are identical and are called bases. A prism is named after the shape of these bases. For example, if a prism has a triangular base it is called a triangular prism.

here, we have,

The formula for the surface area of a prism is SA=2B+ph, where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism.

Base area = 1/2× 8× 6

= 4×6 = 24 cm²

perimeter of the base = 6+8+10 = 24cm²

therefore SA = 2(24)+24×17

= 48+408

= 456cm²

Volume of the prism = base area × height

= 24 × 17

= 408cm³

Answer:

A. Your friend did not factor the variable from the second term.

Step-by-step explanation:

15x - 20xy

Your friend was correct in factoring out 5x. However, when you factor out a component from an expression, you have to change each component in the expression.

This means that factoring out 5x will result in: 5x(3 - 4y).

Therefore, your answer is:

A. Your friend did not factor the variable from the second term.

Answer:

$133.56

Step-by-step explanation:

Multiply 180 and .3 and then subtract that number with 180

you should then get 126

multiply 126 by .06 you should get 7.56

Finally add 126 and 7.56 you should get your final price of 133.56

Answer:

x  ≈ 10.7 ft.

Step-by-step explanation:

Given triangle in the picture is a right triangle.

By applying Pythagoras Theorem in this triangle.

(Hypotenuse)² = (Leg 1)² + (Leg2)²

(14)² = x² + 9²

x² = (14)² - 9²

[tex]x=\sqrt{196-81}[/tex]

[tex]x=\sqrt{115}[/tex]

x = 10.72

Hint 1: Find the direction cosines of AB and BC. Then take their dot product. This will give the cosine of the angle between AB and BC.

Hint 2: The Direction Cosines of PQ, P(x1,y1,z1) and Q(x2,y2,z2), are (±x2−x1(x2−x1)2+(y2−y1)2+(z2−z1)2√,±y2−y1(x2−x1)2+(y2−y1)2+(z2−z1)2√,±z2−z1(x2−x1)2+(y2−y1)2+(z2−z1)2√)

Lines in dimension three do not have to intersect. We find their direction vectors to see if they are parallel.

Note that

AB→=<x2−x1,y2−y1,z2−z1>

and

BC→=<x3−x2,y3−y2,z3−z2>

These vectors are the direction vectors are your lines.

The dot product

AB→.BC→

along with the norms of these vectors determine the angle between the lines if they intersect at all.

... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction

_____

In the real world, it seems probable that Samantha will be offered the choice of using the coupon or the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.

The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.

Answer:

The answer is B. (Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction.)

Answer:

measure of angle XZY = 52 degrees

Step-by-step explanation:

The sum of measure of angles of a circle is 360 degrees.

therefore, m(arc XY) = 360 - (110 + 146)

m(arc XY) = 360 - 256

= 104 degrees

angle XZY is an inscribed angle.

By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.

So, m( angle XZY) = 1/2 * 104

= 52 degrees.

Answer:

Step-by-step explanation:

a right triangle is half of a rectangle and the area of a rectangle is

                 area of rectangle = length × width

Area of a triangle is one half times the length times the width

                 area of triangle =  1/2 × length × width

in this case

                length is the number of the y units  

                width is the number of x axis unit      

    area of triangle =  1/2 × length × width  

    area of triangle =  1/2 × (y units) × (x units)       you need to count and insert
