4(x 2)=48
4x+8=48
4x=40
x=10
Answer:
3ft
Step-by-step explanation:
We are given that
Height of lamp, h=12ft
Height of shadow, l=6ft
Height of shadow of hydrant, l'=1.5ft
Let height of hydrant=h'
We have to find the height of fire hydrant.
All right triangles are similar
When two triangles are similar then, the ratio of their corresponding sides are equal.
Using the property
ft
Hence, the height of fire hydrant=3 ft
Answer:
It is a right triangle
Step-by-step explanation:
Information needed:
Formula: a^2+b^2= c^2
a: leg
b: leg
c: hypotenuse
the longest side is always the hypotenuse, so 17 in
the order of legs don't matter so 8 in and 15 in
Solve:
a^2+b^2= c^2
8^2+15^2= 17^2
64+225= 289
289= 289
Final answer:
It is a right triangle
Answer: v=-81.92
Step-by-step explanation:
Multiply both parts of the equation by 8:
Answer:
w > -2
Step-by-step explanation:
9 + w > 7
Subtract 9 from both sides to end up with w alone on the left side.
w > -2
