Answer:
160
Step-by-step explanation:
6.4 = 0.04x
6.4 / .04 = 160
Acceleration is the rate of change of velocity, which means the change in velocity (vf - vi) with time (t)
<span>where, vf is the final velocity and vi is the initial velocity

Answer:
Step-by-step explanation:
Let's take 4200 as an example.
To convert 4200 into scientific notation, follow these steps:
- Move the decimal 3 times to left in the number so that the resulting number, m = 4.2, is greater than or equal to 1 but less than 10
- Since we moved the decimal to the left the exponent n is positive
n = 3
- Write in the scientific notation form, m × 10^n
= 4.2 × 10^3
Therefore, the decimal number 4200 written in scientific notation is 4.2 × 10^3 and it has 2 significant figures.
Answer: c = 3
Step-by-step explanation: First, make sure you simplify the left side of the equation by combining our <em>c terms</em> together.
So we have 9c - 6c - 2c + 5c which simplifies to 6c.
So now we have the equation 6c = 18.
To solve for <em>c</em> in this equation, we want to get <em>c</em> by itself on the left side of the equation. Since <em>c</em> is being multiplied by 6, to get <em>c</em> by itself, we need to divide by 6 on the left side of the equation. Since we divided by 6 on the left side, we must also divide by 6 on the right side.
On the left side, the 6's cancel out so we're simply left with <em>c</em>. On the right side we have 18 divided by 6 which is 3 so we have <em>c = 3</em>.
Answer: 31 cups
Step-by-step explanation:
We should note that 1 quarts = 4 cups
Therefore, 9 1/2 quarts = 9 1/2 × 4 = 19/2 × 4 = 38 cups
Since only 7 cups of tea remained.after the party, the number of cups of iced tea that the people drank during the party will be:
= 38 - 7
= 31 cups of iced tea
