Last month, Harri drove 850miles in his car. His car's fuel consumption is 45.6 miles per gallon petrol cost £1.09 per litre given that 8 pints=1 gallon work out how much Harri spent on fuel last month

Answers

Using proportions, it is found that Harri spent £76.91 on fuel last month.

What is a proportion?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication and division with the rates.

For this problem, we have that Harri drove 850 miles with a rate of 45.6 miles per gallon hence the number of gallons that Harri used is given as follows:

850/45.6 = 18.64 gallons.

Each gallon is equivalent to 3.78541 liters, hence the number of liters that Harri used is given as follows:

18.64 x 3.78541 = 70.56 liters.

The cost per liter was of £1.09, hence the amount that Harri spent during the last month is given as follows:

70.56 x 1.09 = £76.91.

the mean of the ages of 5 brothers is 13 years. If the ages of four of the brothers are 12, 16, 14, and 8, how old is the fith brother

Answers

I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.

If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.

After that just check your answer by seeing if the mean of all the numbers is the same.

Mina tiene \dfrac{4}{5} 5 4 start fraction, 4, divided by, 5, end fraction de la harina necesaria para hacer una hogaza. Se necesita la misma cantidad de harina para hacer 111 hogaza que para hacer 121212 panes. ¿Cuál es el mayor número de panes que Mina puede hacer con la harina que tiene?

Answers

Answer:

El mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Step-by-step explanation:

Una hogaza equivale a 12 torrejas de pan, si Mina tiene [tex]\frac{4}{5}[/tex] de la harina necesaria para preparar una hogaza. Entonces, el número total de torrejas es [tex]\frac{4}{5}[/tex] de 12 torrejas de pan. Es decir,

[tex]x = \frac{4}{5}\times 12[/tex]

[tex]x = 9.6[/tex]

Puesto que la cantidad de hogazas en un número entero, se trunca al entero más cercano. En consecuencia, el mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

14h 30min + 1h 45min= 16h 15min

16h 15min + 0h 20min=16h 35min

16h 45min - 16h 35min= 10min

So, the answer is yes, she does and she still has 10 minutes free.

Yes she dose 1430+105+20=1555 hence there she made it to the bus stop on time.

Expand the binomial first, then distribute the 4:

Answers

Answer:

Step-by-step explanation:

Set up the following ratio which applies to all angle bisectors and the side opposite.

8 / (x + 4) = 12 / (2x + 1) Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48 Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40 Subtract 12x from both sides

16x - 12x = 40

4x = 40 Divide by 4

4x/4 = 40/4

x = 10

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)

Answers

Answer:

4,3cm

Step-by-step explanation:

Passo 1

Um losango tem 2 diagonais, cujos comprimentos não são iguais

Temos que encontrar o comprimento da segunda diagonal

A fórmula é dada como:

Área de um losango = 1/2 (d1 × d2)

Área do losango = 12 cm²

d1 = Comprimento da primeira diagonal = 8cm

d2 = Comprimento da segunda diagonal = x

12 = 1/2 (8 × x)

12 = 1/2 (8x)

12 = 4x

x = 12/4

x = 3cm

O comprimento da segunda diagonal = 3 cm

Passo 2

A fórmula do comprimento da lateral de um losango é dada como:

s = √d1² + d2² / 2

d1 = 8cm

d2 = 3 cm

s = √8² + 3² / 2

s = √64 + 9/2

s = √73 / 2

s = 8,5440037453 / 2

s = 4,2720018727 cm

Aproximadamente = 4,3 cm
