At a given time of the day, the ratio of the height of an object to the length of its shadow is the same for all objects. If a 3 ft stick in the ground casts a shadow is 1.5ft, find the height of a tree that casts a shadow that is 10.15ft

Answers

Answer 1
Answer:

Answer:

20.3 ft

Step-by-step explanation:

The object-shadow ratio for the stick= 3÷1.5=2:1

The object-shadow ratio is same for all objects.

Let height of the tree be x

2/1 = x/10.15

x=10.15 * 2=20.3

78 is what percent of 110

Answers

Answer: 70.909090909091%

Step-by-step explanation: Reading through the problem we have 78 is, that's 78 equals, what percent, x/100, of 110, times 110.

It's important to understand that percent means over 100 so what percent would simply mean x/100 or any variable but I will be using x.

So we have the equation 78 = (x)/(100) *110

So cross canceling the 110 and 100 to 11 and 10, we have 78 = (11x)/(10)

Multiply both sides by 10 to get rid

of the fraction and we have 780 = 11x.

Now divide both sides by 11 and 70.909090909091 = x.

So, 78 is 70.909090909091% of 110.

$99 cd player 5% tax

Answers

5% tax

tax = 5% of 99

     = 0.05 * 99

tax     = $4.95

Total  = $99 + $4.95 = $103.95

$103.95 will be paid for it.

Hope this explains it.
Here, Price of CD Player = $99
Tax = 5%

Tax amount = 99 × 0.05 = $4.95

Price after tax would be: = $99 + $4.95 = $103.95

So,           In short Tax amount = $4.95
Amount of CD Player after tax = $103.95

Hope this helps!

so 2 miles per 1/2 hour
therfor 1 mile in 1/4 hour since 1/4 is 1//2 of 1/2

so
1 mile per 1/4 hour
2 mile per 2/4 hour
3 mile per 3/4 hour

basically 2 times 3/2=3 so
1/2 times 3/2=3/4=answer

how many more times intense is an earthquake that measures 8 on the richter scale than an earthquake that measures 5

Answers

Answer:

The earthquake that measures 8 on the Richter Scale is 1,000 times more intense than the earthquake that measures 5 on the Richter Scale.

Step-by-step explanation:

This is because each level on the Richter scale is 10 times more intense than the previous one. Therefore it would be ( 10 x 10 x 10 ) aka 1,000.
