Answer: 180 miles x 3 hours = 540
540/2 = 270
270 is the average speed
Step-by-step explanation:
P = k/w^2
<span>first of all you need to find k </span>
<span>But I kind of don't like the units of each value so let say </span>
<span>400KPa = 4 * 10^5 Pa = 4 * 10^5 N/m^2 </span>
<span>2 cm = 2 * 10^-2 m </span>
<span>input values in the equation </span>
<span>4*10^5 = k/(4*10^-4) >>> k = 160 N </span>
<span>P = 160/w^2 </span>
<span>it said if she wears a heel with a width of .5 cm </span>
<span>P = 160(0.5 * 10^-2)^2 >>> P = 6400 KPa</span>
A) x=2; i’m guessing if you meant by 4x+1=x+7
Answer:
2472 students
Step-by-step explanation:
<u>What we know:</u>
- There are 6 schools
- Each school has 412 students
<u>What we're trying to solve:</u>
How many students are there altogether?
To find this, we multiply 412 by 6. Doing this is essentially the same as adding 412 to itself 6 times for each school there is in the district.
412 students × 6 schools
= 2472 students
Therefore, there are 2472 students in the district.
I hope this helps!
Answer:
Step-by-step explanation:
Comment
The square of the tangent = the external segment of the secant * the full length of the secant.
Formula
(x - 1)^2 = (x - 3)*(x - 3 + 5) Combine the right
Solution
(x - 1)^2 = (x - 3)*(x +2) Remove the brackets on both sides
x^2 - 2x + 1 = x^2 -3x + 2x - 6 Combine the right
x^2 - 2x + 1 = x^2 - x - 6 Subtract x^2 from both sides
-2x + 1 = - x - 6 Add 6 to both sides
-2x + 1 + 6 = -x - 6 + 6 Combine
-2x + 7 = - x Add 2x to both sides
-2x+2x + 7 = -x+2x Combine
7 = x
Answer
x = 7
