Answer:
V=16
Step-by-step explanation:
We are given that an inverse variation
We have to find the value of V when p=1/2
To find the value of V we will substitute the value of p
Substitute the value of p
Then, we get
Using multiplication property of equality
Using multiplication property of equality
Hence, the value of V=16
Answer:
x = teaspoon of soda needed = 2 teaspoons of baking soda for 1 teaspoon of salt
y = teaspoons of baking soda needed = 1/2 teaspoons of salt needed for 1 teaspoon of baking soda
Step-by-step explanation:
Teaspoon of salt : Teaspoon of soda
1/8 : 1/4
How much baking soda is needed for 1 teaspoon of salt?
Let
x = teaspoon of soda needed
Teaspoon of salt : Teaspoon of soda
1 : x
Equate both proportion
Teaspoon of salt : Teaspoon of soda
1/8 : 1/4 = 1 : x
1/8 ÷ 1/4 = 1/x
1/8 × 4/1 = 1/x
4/8 = 1/x
Cross product
4*x = 8*1
4x = 8
x = 8/4
= 2
x = 2 teaspoons of
x = teaspoon of soda needed = 2 teaspoons for 1 teaspoon of salt
2. How much salt is needed for 1 teaspoon of baking soda?
Let y = teaspoons of baking soda needed
Teaspoon of salt : Teaspoon of soda = y : 1
Equate the proportion
1/8 : 1/4 = y : 1
1/8 ÷ 1/4 = y / 1
1/8 × 4/1 = y / 1
4/8 = y / 1
Cross product
4 * 1 = 8 * y
4 = 8y
y = 4/8
= 1/2
y = 1/2 teaspoons of baking soda
y = teaspoons of baking soda needed = 1/2 teaspoons needed for 1 teaspoon of baking soda
