A bottle of water contains 450ml. How many litres of water are there in 8 of these bottles

Given:

Temperature in the morning = -2 degrees.

Temperature is dropping at a constant rate.

Temperature after 4 hours = -22 degrees.

To find:

The rate of change of temperature.

Solution:

Let y be the temperature after x hours from the morning.

Temperature in the morning is -2 degrees. It means, the ordered pair is (0,-2).

4 hours later the temperature is now -22 degrees. It means, the ordered pair is (4,-22).

Now, formula for average rate of change or slope is

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

[tex]m=\dfrac{-22-(-2)}{4-0}[/tex]

[tex]m=\dfrac{-22+2}{4}[/tex]

[tex]m=\dfrac{-20}{4}[/tex]

[tex]m=-5[/tex]

Therefore, the change in temperature is -5 per hour. It means the permutate is decreasing by 5 degrees per hour.

Step-by-step explanation: Each game is $25.50 which in math means it has an "x"

So if x=1 then 25.50x says that 1 video game is $25.50

Set up the equation:

200 = 25.50x (divide both sides by 25.50 to isolate the x)

200/25.50 = 7.84

x = 7.84

You can't have 0.84 of a video game, so Roberto can only buy 7 of them.   The answer is correct good job!

The number of games that Roberto can buy [tex]\boldsymbol{8}[/tex] video games.

"To understand the calculation, check below."

When two values are compared, an inequality shows whether one is less than, greater than, or simply not equal to the other.

It's a relation that compares two integers or other mathematical expressions in a non-equal way.

Total amount with Roberto [tex]=\$ 200[/tex]

Let [tex]x[/tex] denotes number of games that Roberto can buy.

Cost of each video game [tex]=\$25.50[/tex]

So,[tex]25.50x\leq 200\\x\leq 7.8[/tex]

Therefore, Roberto can buy [tex]\boldsymbol{8}[/tex] video games.

Answer:

0.5 3/5 5/8 65%

Step-by-step explanation:

Answer:

Your answer is 0.5, 3/5, 5/8, 65%.

Step-by-step explanation:

Convert all numbers to decimals:

0.5 = 0.5

5/8 = 0.625

65% = 0.65

3/5 = 0.6

Arrange the numbers accordingly: 0.5, 0.6, 0.625, 0.65. Hence, your answer is 0.5, 3/5, 5/8, 65%.

Answer:

Oil changes = 5

Vincent = 10 oil changes

Warren = 10 oil changes

Step-by-step explanation:

Vincent = 5 + h

Warren = 2h

Where,

h = number of oil changes

How long will that take?

Vincent = Warren

5 + h = 2h

5 = 2h - h

5 = h

h = 5

Number of oil changes = 5

How many oil changes will Vincent and Warren each have done?

Vincent = 5 + h

= 5 + 5

= 10 oil changes

Warren = 2h

= 2(5)

= 10 oil changes

Answer ok i will

Step-by-step explanation:

Answer:

Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.

Volume = Length × Width × Height

Calculate the volume of this rectangular object.

Length = 3 cm

Width = 3 cm

Height = 12 cm

Volume = l × w × h

Volume = 3 cm × 3 cm × 12 cm

Volume = 108 cm3

Notice that the units for volume are cubic centimeters (cm3).

So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.

Answer:

It is the 4th graph

Step-by-step explanation:

Work Shown:

s = side length = 15 inches

SA = surface area of the cube

SA = 6s^2

SA = 6*15^2

SA = 6*225

SA = 1350

The surface area is 1350 square inches.

Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.

Answer:

1350 [tex]in^{2}[/tex]

Step-by-step explanation:

A cube has six sides. To find the area of a square, multiply the length by itself:

15 x 15 = 225

Since each side is the same (because the box is a cube), simply multiply 225 by 6 (the number of sides on a cube):

225 x 6 = 1350

Answer:

i think it is Move the decimal after the number 1.

Step-by-step explanation:

it the text it says

"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."

Awnser:

(C) Move the decimal after the number 1.

Step-by-step explanation:

The correct answer is Move the decimal after the number 1. The first step in converting a large number to a scientific notation is to determine the coefficient, which is always greater than 1 and less than 10.

Answer:

y=-2x+b

Step-by-step explanation:

Answer: the number must be placed in the box is 9

suppose: the number must be placed in the box is x

have:

5u + 3(4u - 6) = -3u -27 + 20u + x

⇔ 5u + 12u - 18 = -3u - 27 + 20u +x

⇔ 17u + 3u - 20u = -27 + 18 + x

⇔ 0 = x - 9

⇔ x = 9

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Simplifying both sides gives 

17u - 18 = 17u - 27 + ▢.

Subtracting 17u from both sides gives

-18 = -27 + ▢. 

If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.

Answer:

Step-by-step explanation:

surface area = 2( LW + LH + WH)

where L = Length = 9

          W = Width = 2

          H = Height = 9

plugin values into the formula:

surface area = 2 ( LW + LH + WH)

                     = 2 ( 9*2  + 9*9  + 2*9 )

                     = 2 ( 18 + 81 + 18 )  

                     =  2 (117)
