When x is doubled, y is doubled. When z is multiplied by 5/8, so is y. The result of both changes is that y is multplied by 2·(5/8) = 5/4. The new value of y is
... y = 5/4·320 = 400
_____
If you really want to, you can use the formula
... y = kxz
and compute the value of k as
... k = y/(xz) = 320/(4·16) = 5
Then use this formula with the new values of x and z:
... y = 5·8·10 = 400
Answer:
Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.
2(10.40)=20.80. The total of both shirts is $20.80
Answer: ∆LAW ≅ ∆WKL
By rule - ASA congruence postulate.
Step-by-step explanation:
Given: In ∆LAW and ∆WKL
AW⊥WL and WL⊥KL
therefore, by ASA postulate of congruence
∆LAW ≅ ∆WKL
- ASA postulate says that if two angles and the included side of one triangle are congruent to two angles and the included side of second triangle, then the triangles are said to be congruent.
