A 36 ft tree casts a 9 ft shadow at the same time a building casts a 15 ft shadow. How tall is the building?

mote1985 [20]

Answer: The height of the tree is 27f t

Step-by-step explanation: We can set up a proportion comparing the height of each object to the length of the shadow.

h/s

h/15=18/10

Cross multiply

10.h= 18*15

10h=270

Use the multiplicative Inverse

10 h/ 10 = 270 /10 =27

Help me please. ------------------------------------------------

ladessa [460]

Answer:

Alicia

Step-by-step explanation:

First, convert the mixed fractions into improper fractions

Alicia

Distance: 5 1/2 = 11/2 = 5.5 miles

Time: 1 2/5 = 7/5 = 1.4 hours

Carlos

Distance: 8 1/8 = 65/8 = 8.125 miles

Time: 2 1/2 = 5/2 = 2.5 hours

Henry

Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles

Time: 1 1/10 = 11/10 = 1.1 hours

Zoe

Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles

Time: 1 3/10 = 13/10 = 1.3 hours

After that, divide the distance by the time

Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )

Carlos = 8.125 / 2.5 = 3.25

Henry = 3.6 re / 1.1 = 3.3 reoccuring

Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )

Looking at these answers, we determine which rate is the greatest

Alicia = 3.93

Carlos = 3.25

Henry = 3.3 re

Zoe = 3.54

Alicia hiked the highest rate.

OLEGan [10]

Answer:

8y^3z

Step-by-step explanation:

8, y^3 and z are common to both expressions. Thus, the GCF is 8y^3z.

The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 4 points.

Anastasy [175]

Using Chebyshev's Theorem, it is found that:

At least 75% of the exam scores fall between 76 and 92.

---------------------------

Chebyshev's Theorem states that the percentage of measures within k standard deviations of the mean is of at least $100(1 - \frac{1}{k^{2}})$ .

With k = 2, that is, within 2 standard deviations of the mean:

$P = 100(1 - \frac{1}{2^{2}})$

$P = 100(1 - \frac{1}{4})$

$P = 100(\frac{3}{4})$

$P = 75$

At least 75% of the measures are within 2 standard deviations of the mean.

84 - 2(4) = 76

84 + 2(4) = 92

Thus, at least 75% of scores between 76 and 92.
