Answer:
the length of its altitude is 34.64 cm
Step-by-step explanation:
Given;
length of a side of the equilateral triangle, L = 40 cm
All the sides of an equilateral triangle are equal
To get the altitude of the triangle, draw a perpendicular line from one of the vertices to intersect the opposite side.
Let the altitude = h
half of the opposite side intersected by the altitude = 20 cm
Apply Pythagoras theorem to determine the altitude 'h'
h² = 40² - 20²
h² = 1200
h = √1200
h = 34.64 cm
Therefore, the length of its altitude is 34.64 cm
Answer:
a. Velocidad = 16 m/s
b. Deceleración = 0.64 m/s²
Step-by-step explanation:
Dados los siguientes datos;
Tiempo = 25 segundos
Distancia = 400 metros.
a. Para encontrar la velocidad;
Velocidad = distancia/tiempo
Velocidad = 400/25
Velocidad = 16 m/s
b. Para encontrar la desaceleración;
Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.
Deceleración = (v - u)/t
Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.
Deceleración = (0-16)/25
Deceleración = 16/25
Deceleración = 0.64 m/s²
Answer:
I believe it's D
Step-by-step explanation:
Hope this helps, can i have brainliest? Pleeez?
6h+5(h-5)= 52
Mutiply the bracket by 5
(5)(h)(5)(-5)= 5h-25
6h+5h-25= 52
move -25 to the other side
sign changes from -25 to +25
6h+5h-25+25= 52+25
6h+5h= 77
11h= 77
divide by 11
11h/11= 77/11
Cross out 11 and 11, divide by 11 and becomes 1*1*h= h
h= 7
Answer: h= 7
Answer:
8:10am
Step-by-step explanation:
You have to leave home because it takes you 15 minutes to walk to the bus stop so that will be 8:25am
takes you half an hour to get to job 8:55am
then 5 minutes to check in and you will be on time
Answer 8:10am
