measuring angles with a protractor​

Answer:

x = -2, y = -8

Step-by-step explanation:

13(y + 6) - 6y = 22

=> 13y + 78 - 6y = 22

=> 7y = -56

=> y = -8

x = -8 + 6

=> x = -2

Answer: A Diameter x pi= circumference

Step-by-step explanation:

The circumference of a circle is given as:

= 2πr

where,

π = pi = 3.14

r = radius

Note that diameter = 2 × radius.

Therefore, circumference = 2πr = πd

Therefore, circumference will be pi multiplied by diameter. The correct option is A.

The correct statement is:

A. Diameter x pi = circumference

Respuesta:

h = V / 15

Explicación paso a paso:

El volumen de un prisma rectangular se calcula usando la relación:

Largo ancho alto

Donde, largo y ancho son la dimensión de la base

Por eso,

Volumen = Base * altura

Volumen = (5 cm * 3 cm) * altura

De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h

V = 15h

Divide ambos lados entre 15

V / 15 = 15h / 15

V / 15 = h

Answer:

55 centimeters

Step-by-step explanation:

It is a right triangle which means it will add up to 90 degrees. You would start by adding 20 and 15 which is 35 and then subtract 35 from 90 to get 55. I hope this helped :)

Answer:

x = 5

Step-by-step explanation:

TU is a tangent segment with length 6.  RT is a secant segment.

In the circle, the square of the tangent is equal to the product (multiply) of the part of the secant outside the circle and the secant's entire length.

Words don't work well here, do they!

In symbols,  (ST)(RT) = (TU)^2

Answer: 37 donuts

Step-by-step explanation:

coffee for 2,

donuts for 1.5

c = coffee

d = donuts

lets make an equation

c*2 + (80-c)*1.5 = 141.5

from this we get:

c= 43.

if c = 43, then d is 80-43 = 37.

they sold 43 coffees, and 37 donuts.

lets check the math

43*2+37*1.5 = 141.5. math checks out

Answer:

Step 1

Step-by-step explanation:

They're all wrong expansions but step 1 was where he made his first error... He shifted the bracket putting 3x inside the bracket... While the other steps the first expansion of 3x eliminating the bracket was correct.

The correct expansion is meant to be 3x + 21 + 5 = 3x + 26

As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.

Assumption : Let us assume the length as "l" and width as "b". So,

[tex] \twoheadrightarrow \quad\sf{ Length =2(Width)-5} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.

[tex]\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(2b-5+b)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(3b-5)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 6b - 10} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50+10= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{60= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{\cancel{\dfrac{60}{6}}=b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{10\; m = Width }} \\[/tex]

Now, finding the length. According to the question,

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=2(10)-5\; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=20-5\; m} [/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{15\; m = Length }} \\[/tex]

Therefore, length and breadth of the rectangle is 15 m and 10 m.

Step-by-step explanation:

I am not sure what your problem is.

is this one line just a question to you ? is x=6 a solution ?

if that is the case then ... yes, x=6 is a solution to the inequality.

x - 5 < 10

x < 15

so, 6 < 15 is true, therefore, x=6 is a valid solution

Answer:

(0, -2)

Step-by-step explanation:

The x- and y-coordinates indicate the position of a point in the 2D coordinate plane relative to the origin. The coordinates are written as an ordered pair of numbers (x, y), where x indicates horizontal position and y indicates vertical position.

Example

The position of the point in the figure below is specified by the ordered pair, (6, 4). 6 is the x-coordinate and 4 is the y-coordinate of the point.
