Find two positive consecutive odd integers whose products is 99.

tensa zangetsu [6.8K]

Answer:

9,11

Step-by-step explanation:

let the numbers be x, x+2 (since consecutive odd integers have a difference of 2)

therefore;

x(x+2)= 99

x²+2x=99

I usually solve the sum like this,

we need to find the nearest square number ( number smaller than the number on the R.H.S)

here, it is 81, whose square root is 9. therefore the solution is 9

verification:

(9)²+2*9=99

81+18=99

99=99

hence, 9 is the solution. therefore the positive odd consecutive integers are

x=9

x+2=9+2= 11

verification:

9*11=99

99=99

A kite is flying with its string, which is of length 60 metres, taut.The kite is 20 metres vertically above the ground.a)Find th

chubhunter [2.5K]

a) Due to you have a right triangle, in order to calculate the value of d, use the Pythagorean thorem:

$d=\sqrt[]{(60m)^2+(20m)^2}=\sqrt[]{4000m^2}\approx63.2m$

Hence, the distance d is approximately 63.2m

b) To find the angle of elevation, use the sine function of θ, as follow:

$\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse}=\frac{20m}{60m}=\frac{1}{3} \\ \theta=\sin ^{-1}(\frac{1}{3})\approx19.8 \end{gathered}$

Hence, the angle of elevation is approximately 19.8°

torisob [31]

Answer:

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the price of a burger.

y is the price of a gatorade.

6 burgers and 4 gatorades for $14.10

This means that $6x + 4y = 14.10$

3 burgers and 4 gatorades for $9.15.

This means that $3x + 4y = 9.15$

Will write 4y as a function of x.

$4y = 9.15 - 3x$

Replacing in the first equation:

$6x + 4y = 14.10$

$6x + 9.15 - 3x = 14.10$

$3x = 4.95$

$x = \frac{4.95}{3}$

$x = 1.65$

And

$4y = 9.15 - 3x$

$4y = 9.15 - 3*1.65$

$4y = 4.2$

$y = \frac{4.2}{4}$

$y = 1.05$

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.
