A hot water tap filled a bath in 7 1/2 minutes,while a cold water tap fills it in 5 minutes,how long will it take to fill the bath when both taps are turned on together?​

Answers

Answer 1

Answer:

3 minutes

Step-by-step explanation:

Let's say that the bathtub is 15L

It would take 7.5 mins to fill 15L

15L/7.5 = 2L per minute

The other tap would take 5 minutes to fill 15L

15L/5 = 3L per minute

3L per minute + 2L per minute = 5L per minute

15L/5L per min = 3 minutes

Sorry for the delay. Accidentally pressed the answer button without the answer. Hope I helped.

Parallel = has same slope
On points( 3,4) (-2,2)
(2-4)/(-2-3) = -2/-5 = 2/5 slope

Use same formula: (y2-y1)/(x2-x1)

Find the slope of the other points:
(-2,-5) and (-7,-3)
(-3-(-5))/(-7-(-2)) = 2/-5 = -2/5

(-1, 1) and (-6, -1)
(-1-1)/(-6-(-1)) = -2/-5 = 2/5

(0,0) and (2,5)
(5-0)/(2-0) = 5/2

(1,0) and (6,2)
(2-0)/(6-1) = 2/5

(3,0) and (8,2)
(2-0)/(8-3) = 2/5

Which has same slope of 2/5?

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answers

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Las abejas tienen que hacer 50.000 salidas para obtener 1 quilogramo de miel. ¿Cuántas salidas tendrá que hacer para obtener 5 quilogramos de miel?

Answers

Answer:

Tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

Step-by-step explanation:

Con la información proporcionada, puedes usar una regla de tres para calcular cuántas salidas tendrá que hacer para obtener 5 kilogramos de miel dado que las abejas tienen que hacer 50.000 salidas para obtener 1 kilogramo de miel:

1 kilogramo    →   50.000 salidas

5 kilogramos  →               x

x=(5*50.000)/1

x=250.000

De acuerdo a esto, la respuesta es que tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2.

Public".public String getReverseOrder()Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".4.
