Answer:
The area is 64ft ^2.
Step-by-step explanation:
I believe this is an isosceles triangle and if so our base will be 16ft and our height will be 8ft, knowing this we can solve for the area.
Use the form A=bh/2
Now plug it in...
A=16x8/2
A=128/2
A=64ft ^2
Hope this helps :)
Answer:
There are 7 coins of quarters , 12 coins of dimes and 16 coins of nickels .
Step-by-step explanation:
Mukul has $3.75
1 dollar = 100 cents
3.75 dollar = 375 cents
Let he has x coins of quarters
Since we are given that he has five more dimes than quarters.
So, Dimes = x+5
Since we are given that he has nine more nickels than quarters .
So, nickels = x+9
Now 1 quarter = 25 cents
So, x quarter = 25 x cents
1 dime = 10 cents
So, (x+5) dimes = 10(x+5) cents
1 nickel = 5 cents
So, (x+9) nickels = 5(x+9) cents.
Since he had 375 cents in total .
Thus there are 7 coins of quarters
Coins of dimes = x+5=7+5=12
Coins of nickels = x+9=7+9 =16
Hence there are 7 coins of quarters , 12 coins of dimes and 16 coins of nickels .
Answer:
The height of the tree is Greater than 50 feet, so Iva’s house is not safe
Step-by-step explanation:
Find the height of the tree
Let
h ----> the height of the tree
we know that
The tangent of angle of 50 degrees is equal to divide the opposite side to the angle of 50 degrees (height of the tree) by the adjacent side to the angle of 50 degrees (tree’s distance from the house)
so
tan(50°)=h/50
h=(50)tan(50°)=59.6 ft
therefore
The height of the tree is Greater than 50 feet, so Iva’s house is not safe
