Chris rode his bike 4 miles west and then 3 miles south. What is the
shortest distance he can ride back to the point where he started?
Answers
Answer:
5 miles
Step-by-step explanation:
This is because if you draw a line going west and label it as 4 miles, then draw another line going south and label it 3 miles, you form a right angle, right? So, the fastest way to go back would be taking a diagonal-like route back to the beginning. Does this shape look familiar to you? Right! It's a right triangle. And do the numbers 3, 4, and 5 sound familiar to you? Yup, it's a Pythagorean triplet. If the legs of a right triangle are 3 and 4, the hypotenuse is 5. Why am I saying this? Because, in the drawing you just did, the 4 miles west and 3 miles south were the legs, and the diagonal path back to the beginning is the hypotenuse. Get it now?
Happy to help! :)

Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10

Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c

The restaurant manager suggests that they order one pizza for every 6 people. How many pizzas
should they order?
Answers
First, add up the numbers of players on each team and the coachesto get the total number of people eating.
17 + 21 + 20 + 17 + 9 = 84
Then, you can divide 84 by 6 to see how many pizzas: 84/6 = 14
If you’re teacher wants you to set it up as a ratio, it’s 6/1 = 84/x
Then you cross-multiply:
6x = 84
Divide both sides by 6
x = 14
y=2x-3
y=x+2 system of equations
Answers
Answer:
x = 5
y = 7
Step-by-step explanation:
Since they are both equal to y, we can set them equal to each other.
2x - 3 = x + 2
Combine like terms and isolate the x.
x = 5
Plug in the x to either equation to get the value of y.
y = (5) + 2
