Answer:

about 36.3 feet

Step-by-step explanation:

Let x represent the height of the kite in feet. Then (x-22) is the horizontal distance to the kite. The Pythagorean theorem tells you the string length is related to these distances by ...

... 39² = x² + (x-22)²

... 2x² -44x -1037 = 0 . . . . rearrange to standard form

Using the quadratic formula, the positive solution is ...

... x = (-b+√(b²-4ac))/(2a) . . . . for a=2, b=-44, c=-1037

... x = (44 + √((-44)² -4(2)(-1037)))/(2·2)

... x = 11 + √639.5 ≈ 36.288

The kite is about 36.3 feet above the ground.

5 2/3 gave to her 4 friends how much did each one receive
Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

5 \frac{2}{3} = 5 +  \frac{2}{3} =  \frac{5 \times 3}{3} +  \frac{2}{3} = \\   \frac{15}{3} +  \frac{2}{3} =  \frac{17}{3}

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

\frac{17}{3} \div 4 =  \frac{17}{3} \times  \frac{1}{4} =  \frac{17}{12} \\

So each of her friends receive 17/12 .

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

5 \times  \frac{2}{3} =  \frac{10}{3} \\

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

\frac{10}{3} \div 4 =  \frac{10}{3} \times  \frac{1}{4} =  \frac{10}{12} \\

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

A particular fruit's weights are normally distributed, with a mean of 476 grams and a standard deviation of 36 grams. The heavie
4vir4ik [10]

Answer:

Step-by-step explanation:

Given that:

mean (μ) = 476 grams, standard deviation (σ) = 36 grams. P(z) = 19%

The z score shows by how many standard deviation the raw score is above or below the mean. It is given by the equation:

z=\frac{x-\mu}{\sigma}

Since the 19% weigh more, therefore 81% (100% - 19%) weigh less.

From the normal distribution table, the z score that corresponds to a probability of 81%(0.81) = 0.87

We substitute z = 0.88 in the z score equation to find the raw score. Therefore:

z=\frac{x-\mu}{\sigma}\\0.87=\frac{x-476}{36}\\ x-476=31.32\\x=31.32+476\\x=507.32\\

x ≅ 507 grams

Therefore 19% of fruits weigh more than 507 grams
