A rectangular container is 40 cm by 30 cm by 25 cm. It is filled with
3
water up to 5
of its height. Half of the water is then poured out. How
much water is left in the container? Give your answer in litres.​

Answers

Answer 1

Answer: 9 L

Step-by-step explanation:

Given

The dimension of the rectangular container is [tex]40\times 30\times 25\ cm^3[/tex]

It is filled with [tex]\frac{3}{5}[/tex] of the height

Water present in the container

[tex]\Rightarrow 40\times 30\times 25\times \dfrac{3}{5}\\\\\Rightarrow 18000\ cm^3[/tex]

Also, [tex]1\ L=1000\ cm^3[/tex]

[tex]\therefore 18,000\ cm^3=18\ L[/tex]

Now, half of the water is poured out

So, half is left

[tex]\Rightarrow \dfrac{18}{2}=9\ L[/tex]

Thus, 9 L of water is left in the container

A circular carnival ride has a diameter of 120 ft. Suppose you board a gondola at

the bottom of the circular ride, which is 6 ft above the ground, and rotate 240°

counterclockwise before the ride temporarily stops. How many feet above ground

are you when the ride stops?

Answers

Answer:

The height above ground when the ride stops is 96 feet

Step-by-step explanation:

The given diameter of the carnival ride, d = 120 ft.

The height of the ride above the ground, h = 6 ft.

The angle through which the ride is rotated, θ = 240° counterclockwise

Therefore, we have;

The radius of the ride, r = d/2

∴ r = 120 ft./2 = 60 ft.

We note that at 180° rotation, the ride is at the highest point, [tex]h_{max}[/tex] = 6 ft. + 120 ft. = 126 ft.

When the ride rotates a further 240° - 180° = 60° the height drops from the maximum point by y = 60 ft. × cos (60°) = 30 ft., such that the final height above ground is therefore;

h = 126 ft. - 30 ft. = 96 ft.

The height above ground when the ride stops, h = 96 ft.

What is the total number of unique triangles with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters?\

Answers

Answer:

Total 9 unique triangles can be formed

Step-by-step explanation:

For triangles to be unique, length of one side can be arranged in 3 different ways

Let us  L1, L2 and L3 are the three sides

Now, length of 6.5 cm can be at maximum three positions i.e  L1, L2 and L3

Like wise length of 6.0 cm can be at maximum three positions i.e  L1, L2 and L3

and length of 2.5 cm can be at maximum three positions i.e  L1, L2 and L3

Hence, total ways of making unique triangles are

3 + 3+ 3= 9

I need help finding the area and perimeter you will get plz

Answers

Answer:

I couldn't find the area, but the perimeter is 200.

Step-by-step explanation:

To get the answer of 200 perimeter, all you have to do is add up all the sides of the shape.

10+10+25+25+25+15+15+75 = 200.

After adding up the numbers, you are left with a perimeter of 200.

Respuesta:

No pude encontrar el área, pero el perímetro es 200.

Explicación paso a paso:

Para obtener la respuesta de 200 de perímetro, todo lo que tienes que hacer es sumar todos los lados de la forma.

10 + 10 + 25 + 25 + 25 + 15 + 15 + 75 = 200.

Después de sumar los números, te queda un perímetro de 200.

Mean = 69Median = 69Mode = {68, 70}

===============================================

Explanations:

To get the mean, you add up all of the values and then you divide by N, where N is the number of values in the list. In this case, you'll divide by N = 8.

Adding up all the values gets you 70+68+70+72+68+66+65+73 = 552. Dividing that over 8 then leads to the arithmetic mean of 552/8 = 69

-------

To find the median, you'll first sort the values from smallest to largest. You should have this set {65, 66, 68, 68, 70, 70, 72, 73} after sorting. Next, cross off the smallest and largest values to end up with this smaller set {66, 68, 68, 70, 70, 72}. We do this so we can locate the middle-most item.

Repeat the process of crossing off the smallest and largest items to get {68, 68, 70, 70}. Do so one more time and we get {68,70}.

The midpoint of those two values is (68+70)/2 = 138/2 = 69. The median is 69. The mean and median may not always be the same value.

--------

The mode is the most frequent value. In this case, we have 68 and 70 show up exactly twice for each unique value. This is the most compared to the other unique values that only show up exactly once.

It is possible to have more than one mode, as long those values are more frequent than the rest. We denote the mode as a set, so the mode is {68, 70}

Find whether p = 2 and p=3 are solutions for the equation
7 (p+2)=5 (p+4) ? Justify?​

Answers

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

7(p+2)=5(p+4)

By distributive law

The eqn becomes :

7p + 14 = 5p + 20

collecting like terms ;

7p - 5p = 20 - 14

=> 2p = 6 and

:- P = 3 ( dividing both sides by 2)

P= 3 is the only solution to the equation above and it satisfies the equation.

You use 7 1/2 c flour to make 3 loaves of bread. The second person uses the same recipe. He will make b loves of bread using f cups of flour. Write an equations that represents of the relationship between b and f.

Answers

Answer:

b = 2/5f

Step-by-step explanation:

Cups of flour = loaves of bread

7 1/2 c = 3

c = 3 ÷ 7 1/2

c = 3 ÷ 15/2

= 3 × 2/15

= 6/15

= 2/5

c = 2/5

Cups of flour = loaves of bread

2/5 f = b

b = 2/5f

Diameter (d) of a circle = 16 m.

Radius (r) of a circle = 16/2 = 8 m.

Now, we know,

[tex] \dag [/tex] Formula of Area of a circle is πr².

So, Area of a circle = 3.14 × (8)²

Jane has saved 600 dollars in a college fund. She added money to the account over the next year and at the end of the year, the account had 890 dollars.
!! Write an equation to represent the amount she saved over the year. !!

Answers

Here’s the link.
explanation:

Answer:

S=End amount-Starting amount

Or(with values)

290=890-600

Step-by-step explanation:

So lets get together all our variables.

First, lets create a variable that shows the amount of money saved over the year.

Lets use S, for savings.

Next, lets take our end value, which was 890, and subtract it from our orgninal value.

This will get you the amount of money that Jane earned over the year. This will look like:

890-600

Or

End value=orginal value.

Now S will be equal to the amount of money Jane earned.

So we can write this as:

S=890-600

Or

Amount of money earned=end value-orginal value
