Answer:

2400000 in a hour

Step-by-step explanation:

40,000 × 60 = 2400000 you need to multiple 40,000 with 60 because there is 60 minutes in a hour

Answer:

A or C

Step-by-step explanation:

Answer:

$80

Step-by-step explanation:

plug 40 into each equation for x

50+12(40)

simplify

50+480

simplify

530

10+15(40)

simplify

10+600

610

now subtract 530 from 610

610-530

80

Answer:

400000 pennies

Step-by-step explanation:

A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.

The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:

Height of the building ÷ Thickness of a penny

Height of the building = 2000 feet

Thickness of a penny = 5 × 10^-3 feet

Hence:

= 2000feet/ 5 × 10^-3 feet

= 400000 pennies

Answer: {-7, -6}

Explanation: When an equation has a squared term in it,

it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to 0, then factor.

Since this equation is already set equal to 0, we can factor the left side.

The left side is a trinomial that can be

factored as the product of two binomials.

The first term in each binomial will be a factor of the w².

Since w² factors a w · w, we use a w as our first term.

For the last terms, we use factors of 42 that add

to 13 and these factors are +7 and +6.

So we have (w + 7)(w + 6) = 0.

So either w + 7 = 0 or w + 6 = 0.

Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:

y=2x−5 is a line

Step-by-step explanation:

Explanation: y=2x−3 is in slope intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. The y-intercept is the point at which x=0 and y=−3 , which is point (0,−3) You can plot this point on your graph.

Answer:

g = 1/3 x - 2/3

Step-by-step explanation:

x =3g + 2

Switch sides:

3g + 2 = x

Take away 2 from both sides:

3g = x - 2

Divide both sides by 3:

g = 1/3 x - 2/3

Answer:

3

Step-by-step explanation:

It is number one.

if there are no more than 20, that means there are less. If one doesnt work try number 2.

Answer:

x = 11

Step-by-step explanation:

3 x 11 = 33

33-5 = 28

x = 11

Answer:

10

Step-by-step explanation:

Given

h(x) = 3x - 5

h(x) = 25

3x - 5 = 25

3x = 25 + 5

3x = 30

x = 30 / 3

x = 10

Answer:

[tex]\frac{11}{6} y[/tex]  

Step-by-step explanation:

Since they all have y as the variable, you can simply add the coefficients (number in front of the variable) together. (y = 1y)

[tex]\frac{2}{3} + \frac{1}{6} + 1 = \frac{4}{6} + \frac{1}{6} + \frac{6}{6} = \frac{11}{6}[/tex] or [tex]1\frac{5}{6}[/tex]

Answer:

El precio de la entrada al cine es de $56

Step-by-step explanation:

Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28  ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:

                                                 28 x 2 =$56

El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.

Entonces podemos hacer la siguiente relación matemática: Precio total de las palomitas dos veces por semana = Precio de la entrada a cine.

Answer:

Hi how are you doing today Jasmine

Answer:

1402 tiles

Step-by-step explanation:

so in order to find the amount of glass tiles we will first need to find the surface area of the box

so the surface area formula for a rectangular prism is

2 (wl * hw* hl)

w- width

h- height

l- length

so the width would be 18centimeters

the height would be 7 cm

and the length would be 23 cm

therefore if we plug in the measurements into the equation it will give us a total surface area of

1402cm^2

therefore if Dimitri wants to cover the box with 1cm glass tiles then we take the 1402cm and divide it by 1cm leaving us with the same answer of

1402 tiles

Answer:

slope should be -5

Step-by-step explanation:

the equation is y=-5+42

slope equation form is y=mx+b

m is the slope in the equation, b is the y-intercept(where it hits the line if graphed)

so b should be 42 and slope should be -5

Answer: 15

Step-by-step explanation:

From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:

= 63 × $5

= $315

We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:

= $315 / $20

= 15 3/4

Therefore, he will get 15 $20 bills
