Answer:
15 ft.
Step-by-step explanation:
I will assume that either both objects are standing straight. We can use similar triangles.
We can see that the side 8 is similar to the side 20, since they are both shadows. Therefore, we can set up an equation:
we can cross multiply and get:
8x=120
solve for x:
x=15
Therefore, the lamppost must be 15 feet tall (unless it fell down but we won't talk about that)
Answer:
$18.00
Step-by-step explanation:
To find the total cost of fruit, start by calculating the total cost of each type of fruit. To calculate the total cost for a type of fruit, multiply the fruit's cost per pound by the number of pounds purchased.
Calculate the total cost of the mangoes.
$0.80 per pound × 2 pounds = $1.60
Calculate the total cost of the strawberries.
$1.60 per pound × 0.5 pound = $0.80
Calculate the total cost of the guavas.
$5.20 per pound × 3 pounds = $15.60
Now, add these three totals.
$1.60 + $0.80 + $15.60 = $18.00
So, the total cost of the fruit is $18.00.
75% of 56 is .75 * 56
.75 * 56 = 42
Because you are decreasing, you subtract 42 from 56.
56 - 42 = 14
A 75% decrease of 56 books would leave 14 books.
The answer is 21.
18 classrooms x 35 students in each classroom = 630 total students
630 total students / 30 students in each classroom = 21
