Place a decimal point between the first two digits (4 and 8). Erase the commas and the 0s. So you'll have 4.86 left over after you've done that erasing.
Now ask yourself: "how many places to the right must I move the decimal to get 4.86 to turn back to 48,600,000?"
That would be 7 places to the right. That 7 is the exponent over the 10
<h3>Therefore, the answer is 4.86 * 10^7</h3>
This number is 48.6 million
It should be y1 - y2/x1 - x2 this is supposed to be a fraction
I end up getting -31 - 24/5 + 6 or -31 -24/5 - (-6)
Answer:
x^ ( 6/35)
Step-by-step explanation:
x ^ 2/5 ^ 3/7
We know that a^ b^ c = a^ ( b*c)
x ^ ( 2/5 * 3/7)
x^ ( 6/35)
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
