Answer:

if the side length of a cube = 6, then the surface area of the cube is:

36 + 36 + 36 + 36 + 36 + 36

Step-by-step explanation:

A cube has 6 faces.

so you have to add the faces 6 times to get the total surface area of a cube.

-1 mod 19 please show work a =dq+r

kupik [55]

Answer:

The given expression can be written as -1=19(-1)+18.

Step-by-step explanation:

According to quotient remainder theorem:

For any integer a and a positive integer d, there exist unique integers q and r such that

$a=d\times q+r$

It can also written as

$a\text{mod }d=r$

The given expression is

$-1\text{mod }19$

Here a=-1 and d=19.

$\frac{-1}{19}=19(-1)+18$

$-1\text{mod }19=18$

If -1 is divides by 19, then the remainder is 18. The value of r is 18.

Therefore the given expression can be written as -1=19(-1)+18.

Determine the equation of the circle graphed below.

Rzqust [24]

Answer:

Step-by-step explanation:

(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2}(x−h)

+(y−k)

here

r = 7. (the circle is symmetrical with y - axis )

h = 0. and k = 1

Thus equation of circle is,

(x - 0) {}^{2} + (y - ( - 1)) {}^{2} = {7}^{2}(x−0)

+(y−(−1))

x^2 + (y+1)^2 = 49

Gueguen and Jacob asked waitresses to wear different colored T-shirts on different days for a six-week period and recorded the t

jarptica [38.1K]

Answer:

Dependent Variable = tips left by male customers

Independent Variable = T-Shirt color worn by waitresses

Step-by-step explanation:

Dependent variable is the variable that changes when the independent variable changes.

In other words, when the independent variable is varied, the dependent variable changes. The dependent variable is the effect or outcome of the manipulation of the independent variable.

In the study referred to in the question above, the amount of tips given to waitresses is dependent on the color of the T-shirt the waitresses wear.

Therefore, the dependent variable is T-Shirt color, while the independent variable is the amount of tips given.
