Answer: 97 meters
Step-by-step explanation:
Draw 2 right triangles KLM and ABC.
ML=3.2 m ( is a pole) KL =1.29 m( pole's shadow).
(The triangle KLM is right because we suppose that pole is staying vertically).
In triangle AB is tower's shadow= 39.25 m and BC is the height og tower=x meters?
Triangles KLM and ABC are similar .
So ML/KL=x/AB
3.2/1.29=x/39.25
x=3.2*39.25/1.29= approx 97.36 meters= 97 meters
Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years
Answer:
600 square centimeter.
Step-by-step explanation:
A cube-shaped satellite has side lengths of 10 centimeters.
So, the total surface area of the satellite is 2(10 × 10 + 10 × 10 + 10 × 10) = 600 sq. cm.
{The total surface area of a cuboid having length L, width W, and height H is given by 2(LW + WH + HL)}
Therefore, the least amount of aluminum needed to cover the satellite will be 600 sq. cm. (Answer)
The slope is -2. Please correct me if I’m wrong.
2:3:4
Shortest is clearly 2
(2×7.5):(3×7.5):(4×7.5)
So the sides are 15 , 22.5 and 30
Perimeter = 15 + 22.5 + 30
Perimeter = 67.5
