Answer/Step-by-step explanation:
#8. Using the geometric mean theorem formula, h = √xy, where,
h = x
x = 4 and y = 16
Plug in the values
x = √(4*16)
x = 8
#9. Using the geometric mean formula, h = √xy, where,
h = y
x = 5 and y = 8
Plug in the values into the formula:
y = √(5*8)
y = √40
y = 6.3 (nearest tenth)
#10. Using the geometric mean formula, h = √xy, where,
h = 18
x = 12 and y = y = ???
Plug in the values into the formula:
18 = √(12*y)
Square both sides
18² = 12y
324 = 12y
Divide both sides by 12
27 = y
y = 27
Technically what he did could work, because 2 * 5 can be changed to 5 + 5 which you can get to by counting 5's.
Answer:
15.75
36
15.75
Step-by-step explanation:
Formula
the relationship between these two secants is NQ * NP = NM * LM
Givens
- NP = 32
- NQ = x
- NM = 14
- NL = 14 + 22 = 36
Solution
x*32 = 14*36 Substitute values. Divide by 32
x = 14 * 36/32 Multiply 14 and 36
x = 504/32 Divide by 32
x = 15.75
The answer to the first box is 15.75 or x
The answer to the second box is
LM is assumed to be 22 So LN = MN + LM = 22 + 14= 36
QN = 15.75 is the third answer.
Im hoping you just want an example so here you go
whole number: 16
fraction version of 16: 16/1
to subtract fractions you have to have a common denominator.
so if i had a problem like 6 -1/3
step 1 would be to turn 6 into a fraction: 6/1
step 2 is to find the common denominator:
6/1 -1/3, in this case it is 3, so you multuply the first term by 3
you would then get 18/3 - 1/3, now all you do if subract numerators, 18-3=15
final answer would be 15/3, you can simplify it into 5/1 which is also 5
