Answer:
56,000 = 5.6 x 10^**4
Step-by-step explanation:
56,000 = 56 x 10,000
Inserting decimal:
56 x 1,000 = 5.6 x 10,000
Answer:
56,000 = 5.6 x 10^**4
( btw ^** means exponent )
Y2 + x2 = 53
y − x = 5
y = 5 + x
(5+x)^2 + x^2 = 53
(5+x)(5+x) + x^2 = 53
25 + 10x + x^2 +x^2 = 53
2x^2 + 10x - 28 = 0
(x-2)(x+7)=0
x = 2 , x = - 7
y = 5 + 2
y = 7
y = 5 +(-7)
y = 5 - 7
y = - 2
Answer: he has 128 + d
Step-by-step explanation:
well if he had 128 yesterday and today he got d more just add d to 128 and ull see
for example, lets say d = 16
to find out the total we woukd have to add 16 to 128 (just an example the answer is not d=16)
answer= 128+d
Answer:
h = 19.6 ft
Step-by-step explanation:
Given that,
A 20 ft ladder 4ft from the base of the wall.
The height of the ladder, H = 20 ft
The base distance, b = 4 ft
We need to find the height of the reach. Let it is P.
Using Pythagoras theorem,
or
P = 19.6 ft
So, the height is 19.6 ft.
