: a total of 777 people have to be transported using buses that have 46 seats and vans that have 12 seats. calculate how many bu

Firdavs [7]

777 ÷ 46 = 16 Remainder 41

16 buses and the rest have to fit into vans

41 ÷ 12 = 3 vans remainder 5

we need 4 vans, so the number of empty seats = 12 - 5 = 7

Ans: 16 buses, 7 empty seats in the last van.

What is the length of the hypotenuse of the triangle 18 units 18 StartRoot 2 EndRoot units 36 units 36 StartRoot 2 EndRoot units

posledela

The length of the hypotenuse is $36\sqrt{2}$ .

Given that

Consider triangle DEF.

The legs have a length of 36 units each.

Triangle DEF is shown.

Angle DFE is 90 degrees and angles FDE and DEF are 45 degrees.

The lengths of sides DF and FE are 36 units.

We have to determine

What is the length of the hypotenuse of the triangle?

According to the question

The length of the hypotenuse is determined by using the Pythagoras theorem following all the steps given below.

The length of the hypotenuse is determined by;

$\rm (Hypotenuse)^2= (Base)^2+(Perpendicular)^2\\\\ (Hypotenuse)^2= (36)^2+(36)^2\\\\ (Hypotenuse)^2= 1296+1296\\\\ (Hypotenuse)^2= 2592\\\\ Hypotenuse = \sqrt{2592}\\\\ Hypotenuse = \sqrt{2\times 4 \times 4\times 9\times 9}\\\\ Hypotenuse= 9 \times 4 \times \sqrt{2}\\\\ Hypotenuse= 36 \sqrt{2}\\$

Hence, the length of the hypotenuse is $36\sqrt{2}$ .

Long division<br> 3x+1/6x^6+5x^5+2x^4-9x^3+7x^2-10x+2

inna [77]

$(6 x^{6}+5x^{5}+2x^{4}-9x^{3}+7x^{2}-10x+2) / (3x+1)$

We divide first number from first parenthesis with first number from second parenthesis. Then the resulting number we multiply by all numbers in second parenthesis and substract from first parenthesis.

$6 x^{6}/3x = 2 x^{5} \\ \\ 6 x^{6}+5x^{5}+2x^{4}-9x^{3}+7x^{2}-10x+2 - 6 x^{6} -2 x^{5} = 3x^{5}+2x^{4}-9x^{3}+7x^{2}-10x+2\\$

We repeat previous steps until we run out of numbers:
$3x^{5}/3x=x^{4} \\ \\ 3x^{5}+2x^{4}-9x^{3}+7x^{2}-10x+2-3x^{5}-x^{4}= \\ \\ x^{4}-9x^{3}+7x^{2}-10x+2 \\ \\ \\ x^{4}/3x= \frac{1}{3} x^{3} \\ \\ x^{4}-9x^{3}+7x^{2}-10x+2-x^{4}- \frac{1}{3} x^{3}= \\ \\ - \frac{28}{3} x^{3}+7x^{2}-10x+2 \\ \\ \\ - \frac{28}{3} x^{3}/3x= - \frac{28}{9} x^{2} \\ \\ - \frac{28}{3} x^{3}+7x^{2}-10x+2+ \frac{28}{3} x^{3}+ \frac{28}{9} x^{2} = \\ \\ \frac{91}{9} x^{2}-10x+2$
$\frac{91}{9} x^{2}/3x=\frac{91}{27} x \\ \\ \frac{91}{9} x^{2}-10x+2-\frac{91}{9} x^{2}-\frac{91}{27} x= \\ \\ -\frac{361}{27} x+2 \\ \\ \\ -\frac{361}{27} x/3x=-\frac{361}{81} \\ \\ -\frac{361}{27} x+2+\frac{361}{27}x+\frac{361}{27}= \\ \\ \frac{415}{27}$

We are left with a number that has no x inside. This is remainder.
The final solution is sum of all these solutions and remainder:
$(2 x^{5}+x^{4}+\frac{1}{3} x^{3} - \frac{28}{9} x^{2} +\frac{91}{27} x)+(-\frac{361}{81} )$
