There is 2 ways to solve this type of question.
Method 1
--------------------------------------------------
Formula
--------------------------------------------------
a² + b² = c²
--------------------------------------------------
Apply the formula
---------------------------------------------------
(7√2)² + (7√2)² = c²
c² = 98 + 98
c² = 196
c = √196
c = 14
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------

Method 2
--------------------------------------------------
Identify the triangle
--------------------------------------------------
This is a special triangle
45° - 45° - 90°
--------------------------------------------------
Property of the Angles
--------------------------------------------------
x - x - x√2
--------------------------------------------------
Find hypotenuse
--------------------------------------------------
Given that the non-hypotenuse is 7√2
Hypotenuse = (7√2)(√2)
Hypotenuse = 7 x 2
Hypotenuse = = 14cm
--------------------------------------------------
Ans: The diagonal length is 14cm
--------------------------------------------------
Answer:
After 16 weeks she will have 145 dollars left in her account.
Step-by-step explanation:
since 145 represents the amount of money in her account we will substitute that for "y" and solve for "x"
145=-27x+577
145-577=-27x
-432=-27x
-432/-27= -27x/-27
16=x
Answer:
2/3, 0.6, 1/2, 0.12
Step-by-step explanation:
1/2, 0.12, 2/3, 0.6
im going to switch each to decimal if it isn't already
1/2 = 0.5
2/3 = 0.666 repeated
so now we have
0.5 , 0.12, 0.666 repeated, 0.6
now im going to put them in order
0.666 repeated, 0.6, 0.5, 0.12
now im going to change them back
2/3, 0.6, 1/2, 0.12
Answer:
36+42=6(6+7)
Step-by-step explanation:
6x6 is 36 and 6 times 7 is 42.
The distributive property makes this equation true.
Multiply the term outside of the parentheses by each term in the parentheses and then add both terms. In this case the terms are 36 and 42.
Answer:
Step-by-step explanation:
t is the number of years since 2003.
f(t) = $18,500×0.88^t
t = 2 in 2005
f(2) = $18,500×0.88²≅ $14,300
