Answer:

31, 32, 29, 31

u < 28

Step-by-step explanation:

To find if a value works for an inequality, one has to substitute in the value and simplify. If the resulting equation is true, then the value is a part of the solution set of the inequality.

When simplifying an inequality, one must follow all the same rules as simplifying an equation. The only difference is that when one multiplies or divides by a negative number one must flip the inequality sign for the inequality to remain true. In this case, this rule won't come into play.

u < 28

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

Liz is watching a film at the cinema.

A bus leaves the bus stop at 1645
Does Liz get to the bus stop in time to get this bus?
You must show all your working.

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.


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.

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.
