The distance he has traveled vertically to the nearest yard in combined trip is 111 yards.
<em><u>Solution:</u></em>
Given that,
Each step is 8 inches high
There are a total of 50 stairs
So the height of 50 stairs is:
Height of 50 stairs = 50 x 8 = 400 inches
Joseph makes 10 round trips up and down the stairs
So, joseph has went up 10 times and he came down 10 times
We need to find the distance he has traveled vertically in the combined trips
Therefore,
Number of times he went up = 10
We know that,
height of 50 stairs = 400 inches
Therefore,
Distance traveled up = 10 x 400 = 4000 inches
Convert to yard
1 yard = 36 inch
Therefore,
Therefore, the distance he has traveled vertically to the nearest yard in combined trip is 111 yards
Answer:
Answer is -2
Step-by-step explanation:
Half life means exactly 1/2 of what's left decays
example
if yo has 16grams
if half life is 1 hour, after 1 hour, 8g is left
after another hour, 4g is left
after another your, 2g is left
etc
so find how many half lifes have elapes
so
the amount left after n halflives when you start with P amount is
A=P(1/2)^n
5hr=60*5=300mins
300/30=10
10 half lifves
P=1500
n=10
A=1500(1/2)^10
A=375/256
A≈1.46484g
about 1.5g left
The area of the given figure is 56 sq cm
Step-by-step explanation:
Given,
The figure consists of 5 different diagrams: 4 triangles and a square
Each side of square = 4 cm
Height(h) of the triangle = 5 cm
Base(b) of the triangle = 4 cm
To find the area of the given figure
Formula
Area of square = side × side sq cm
Area of triangle = 
×base × height
So, area of square = 4 ×4 sq cm = 16 sq cm
Area of triangle = ×4×5 sq cm = 10 sq cm
The area of 4 triangles = 10×4 sq cm = 40 sq cm
Hence the area of the given diagram = 40 + 16 sq cm = 56 sq cm
