Jadynn's washing machine holds l,086 liters of water. how much water dose it hold in gallons? A gallons is approximately 3.79 liters. round to the nearest tenth

Answers

Answer:

286.5 gallons of water

Step-by-step explanation:

1,086 ÷ 3.79= 286.5435356

Round to the nearest tenth

286.5

Answer:

286.54 gallons

Step-by-step explanation:

You have 1,086 liters and you are trying to find how many gallons it is

Luckily you are given how many liters go into a gallon

So from there it's simple division

1,086/3.79 = 286.5435356200528

Now, it tells you that you only need to round to the nearest tenth. And since the nearest tenth isn't greater than 5, you can just leave it as 286.54

So, 286.54 gallons is the amount that the washing machine holds

Find the length for segment AB. Round to the nearest unit if necessary and enter as a whole number.

Answers

Answer:

The length for segment AB is 5 units

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We must find the length for the segment AB. The coordinates of the endpoints are A(-3,2) B(0,6).

Calculating the distance:

[tex]d=\sqrt{(0+3)^2+(6-2)^2}[/tex]

[tex]d=\sqrt{3^2+4^2}[/tex]

[tex]d=\sqrt{9+16}[/tex]

[tex]d=\sqrt{25}[/tex]

d = 5 units

The length for segment AB is 5 units

Which of the following shapes are rhombuses ? Choose two correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!

Answers

Answer:

Hi there! Your answer is C and D

Step-by-step explanation:

You might know that a Rhombus is a special type of parallelogram whose all sides are equal. The difference between a square and a rhombus is that all angles of a square are right angles, but the angles of a rhombus need not be right angles. So, a rhombus with right angles becomes a square. B is not because all sides are equal and it has right angles. A is not because it does not have equal sides. I hope this helps! :]

you buy 6 apples for $2.70 write and equation that can be used to express the relationship between the total price t and the number of apples a you buy.


1. t= 2.70a

2. t=0.45a

3. t=6a

t= 2.22a​

Answers

Answer:

The correct answer is: 2. t=0.45a

Step-by-step explanation:

Let t be the price of apples

and a be the number of apples

The price and quantity are directly proportional

[tex]t \propto a[/tex]

Removing the proportionality symbol introduces a proportionality constant in the equation

[tex]t = ka[/tex]

So far we know that cost of 6 apples is $2.70

Putting in the equation

[tex]2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45[/tex]

Putting the values of k will give us:

[tex]t = 0.45a[/tex]

Hence,

The correct answer is: 2. t=0.45a

Find the slope of AB. If it is a fraction such as 1/2, write as 1/2 without spaces. (3 points)

Answers

Answer:

The slope of AB is 4/3

Step-by-step explanation:

The Slope of a Line

If a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

It's required to find the slope of the line AB shown in the figure. The coordinates of the endpoints are A(-3,2) B(0,6), thus the slope is:

[tex]\displaystyle m=\frac{6-2}{0+3}[/tex]

[tex]\displaystyle m=\frac{4}{3}[/tex]

The slope of AB is 4/3
