So, first you have to move your decimal to where there is one number in the ones place. That would be 5.26. Then you would put it I the equation 5.26 x 10 ^3, because you moved the decimal 3 times.

11. Rocco and Biff are two koalas sitting at the

bagirrra123 [75]

Answer:

Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

Step-by-step explanation:

Let the height of Biff's tree be represented by x, so that the height of Rocco's tree is $\frac{x}{2}$ .

Draw a straight line from Rocco's point of view to a point t to the middle of Biff's tree. This line divides x into two equal parts, and the angle is divided into $35^{0}$ each.

By alternate angle property,

Tan $35^{0}$ = $\frac{\frac{x}{2} }{10}$

$\frac{x}{2}$ = Tan $35^{0}$ × 10

= 7.00021

⇒ x = 2 × 7.0021

= 14. 0042

x = 14

Therefore, Biff's tree is 14 m off the ground and Rocco's tree is 7 m off the ground.

The age of professors at GHC is normally distributed with a mean of 42 years and a standard deviation of 5 years. A 30-year-old

FinnZ [79.3K]

$30=42+5x\implies 5x=-12\implies x=-\dfrac{12}5=-2.4$

So a 30 year old professor would be 2.4 standard deviations less than the mean.

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One a

Minchanka [31]

Answer:

II. One and only one solution

Step-by-step explanation:

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.

Let assume the equation is given as;

x + 3y = 11 .... 1

x - y = -1 ....2

Using elimination method

Subtract equation 1 from 2

(x-x) + 3y-y = 11-(-1)

0+2y = 11+1

2y = 12

y = 12/2

y = 6

Substitute y = 6 into equation 2:

x-y = -1

x - 6 = -1

x = -1 + 6

x = 5

Hence the solution (x, y) is (5, 6)

Hence we can say the equation has One and only one solution since we have just a value for x and y

Area enclosed by one loop of r=3sin(5theta)

MA_775_DIABLO [31]

Hello,
$Area= \int\limits^a_b {\rho^2} \, d\theta$

$\frac{1}{2} \int\limits^{\frac{\pi}{5}} _0 {(3\ sin(5\theta))^2} \, d\theta\\\\
=\frac{9}{4} \int\limits^{\frac{\pi}{5}} _0 {(1-cos(10\theta))} \, d\theta\\\\
=\frac{9}{4} [\theta-\frac{sin(10\theta)}{10}]^\frac{\pi}{5}} _0 \\\\
=\frac{9\pi}{20}$
