We know that
[surface area ]=2*[area of the base]+[perimeter of the base]*height
area of the base=10*8.7/2-----> 43.5 cm²
perimeter of the base=10*3----> 30 cm
height of the prism=15 cm
[surface area ]=2*[43.5]+[30]*15------->537 cm²
the answer is
<span>the approximate surface area of the prism is 537 cm</span>²
Given that the angle of incidence is equal to the angle of reflection, we can state tha the angle formed by the eyes of Jason with the mirror is equal to the angle formeb by the top of the three with the same mirror.
Then, you can write this similarity equation:
[height of the eyes of Jason] / [distance from the poistion of Jason to the image on the mirror] = [height of the tree / distance from the mirror to the base of the tree]
6feet / 8feet = x/40feet
x = 40feet *[6/8] = 30 feet.
Answer: 30 feet.
Answer:
The domain of f(x) corresponds to the set of real numbers.
D f(x) ∈ ∀X; D f(x) ∈ R
Step-by-step explanation:
f(x)=X+18-3X-15
f(x)=-2X+3 (right line with negative slope)
This function exists for all values of X, so the domain corresponds to the set of real numbers.
D f(x) ∈ ∀X; D f(x) ∈ R
Now find equation of the graph. It passes through the point (2,3), and intersects y-axis at -2.
Answer:
The percent decrease in the number of cheese sticks you can buy for $1 is 80%.
Step-by-step explanation:
Given : Cheese sticks that were previously priced at "10 for $1" are now "2 for $1".
To find : The percent decrease in the number of cheese sticks you can buy for $1 ?
Solution :
The formula used to find percent decrease is given by,
The price change from 10 to 2,
The percent decrease in the number of cheese sticks you can buy for $1 is 80%.
