Step-by-step explanation:

karl filled up the tank of his truck with 400 liters of fuel and set out to deliver a shipment of bananas to alaska. the truck consumed 0.8 liters of fuel for each kilometer driven.

Answers

The graph of the relationship between the amount of fuel remaining in the trucks tank (in liters) and distance driven (in kilometers) is a linear equation given by, y = 400 - 0.8x

Given that Karl filled up the tank with 400 liters of fuel initially.

As time passes and more distance is covered, the amount of fuel will decrease. Thus the amount remaining is inversely proportional to the distance driven.

Let 'x' be the distance driven (in kilometers) by the truck and 'y' be the remaining fuel (in liters) in the tank.

It says that the truck consumes 0.8 liters of fuel for each kilometer driven.

Then the linear equation modelling this will be :

y = 400 - 0.8x

The graph can be drawn with values of 'x' on the x-axis and the values 'y' on the y-axis.

What is the surface area of the cuboid?

Answers

Answer:

Step-by-step explanation:

remember that the surface area is

S=2lw+2lh+2hw

S=2(15*20)+2(15*8)+2(8*20)=600+240+320=1160 cm^2

The surface area of the cuboid is 1160 square cm whose dimensions are

l= 20cm, w= 8 cm and h = 15 cm.

Given:

Length = 20 cm

width = 8 cm

Height = 15 cm

So, the formula for Surface area of Cuboid is

= 2(lw+ wh + lh)

Substituting the values l= 20cm, w= 8 cm and h = 15 cm into the formula as

= 2(lw+ wh + lh)

= 2 (20 x 15 + 8 x 15 + 8 x 20)

= 2 (300 + 120 + 160)

= 2 (580)

= 1160 square cm

What are the number of blocks?

Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).

Ratio of prism shaped blocks to pyramid shaped blocks = number of prism shaped blocks : number of pyramid shaped blocks

4 : 1

Number of pyramid blocks when there are 16 prism shaped blocks : 16 / 4 = 4

Total number of blocks : 4 + 16 = 20 blocks

Number of prism blocks when there are 35 blocks : (ratio of prism blocks /sum of ratios) x  total number of blocks

A certain game gives scores between 0 and 5.
Trinity played 6 times and her mean score was 4.5.
Jayden played 4 times. If both players have the same
sum of scores, what was Jayden’s mean score?

Answers

Answer:

The mean value of Jayden is 6.75 .

Step-by-step explanation:

Given that the formula for mean is (total sum of scores) ÷ (total number of times). So first, we have to find the total sum of scores that Trinity gets :

[tex] \frac{total \: scores}{6} = 4.5[/tex]

[tex]total \: scores = 4.5 \times 6[/tex]

[tex]total \: scores \: = 27[/tex]

Assuming that Jayden also gets the score of 27 and played only 4 times so we have to find the Jayden's mean value :

[tex]mean = \frac{27}{4} [/tex]

[tex] mean = 6.75[/tex]

Simply the equation 3x+1=2x+5

Answer:4

Step-by-step explanation: 3x+1−2x=2x+5−2x

                                               x + 1 = 5

                                               x+1−1=5−1

                                                x=4

Answer:

Simplifying

3x + -1 = 2x + 5

Reorder the terms:

-1 + 3x = 2x + 5

Reorder the terms:

-1 + 3x = 5 + 2x

Solving

-1 + 3x = 5 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-1 + 3x + -2x = 5 + 2x + -2x

Combine like terms: 3x + -2x = 1x

-1 + 1x = 5 + 2x + -2x

Combine like terms: 2x + -2x = 0

-1 + 1x = 5 + 0

-1 + 1x = 5

Add '1' to each side of the equation.

-1 + 1 + 1x = 5 + 1

Combine like terms: -1 + 1 = 0

0 + 1x = 5 + 1

1x = 5 + 1

Combine like terms: 5 + 1 = 6

1x = 6

Divide each side by '1'.

x = 6

Simplifying

x = 6

Answer is 6

please help what’s the domain and range

Answers

Answer & Step-by-step explanation:

The domain is the x values and the range is the y values.

Domain:

Note the lowest x values the line includes. Although it starts at x=2, it curves back to x=1 and then curves past 1. Therefore:

[tex]domain:x\geq 1[/tex]

x is greater than or equal to 1.

Range:

Find the lowest y value that is included in the line. Since the line starts at y=-1 and only moves upward after then:

[tex]range:y\geq -1[/tex]

the y values are greater than or equal to -1.
