they each get 1 slice because the father took half the pizza.
In sailing, it is not possible to head straight into the wind. In order to get upwind, a sailboat simply sails at an angle to the wind and then turns to sail back toward where it wants to go. Assume that a boat needs to get directly upwind 6000 m. If it sails off at a 45 degree angle to the wind and then turns back 90 degrees towards the original goal, how far would it have to sail to get directly upwind 6000 meters? Round to the nearest tenth.
Distance to get directly upwind 6000 meters: ____________________ meters
6000
4242.6
8485.3
10392.3
Answer:
C. 8485.3 meters
Step-by-step explanation:
Think of the sailboat’s path as a 45-45-90 right triangle.
The hypotenuse is the 6000 meter distance.
In this way the leg will be the hypotenuse divided by √2.
So 6000/√2 or 4242.64 meters.
Remember that the sailboat has to turn and head back toward its goal and travel another 4242.64 meters.
Thus, your answer is 4242.64 x 2 = 8485.28 meters or 8485.3 meters.
In this exercise we have to use the knowledge of triangles to calculate the distance that one of the sides has:
Letter C
Some information given in the statement about the triangle:
Sailboat’s path as a 45-45-90 right triangle.The hypotenuse is the 6000 meter distance.So performing the calculation we have:
[tex]6000\sqrt{2}=4242.64 \\4242.64 * 2 = 8485.28[/tex]

Solve 2x + 5 = 12
what’s the what is x
Answer:
x = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
Given
2x + 5 = 12 ( subtract 5 from both sides )
2x = 7 ( divide both sides by 2 )
x = [tex]\frac{7}{2}[/tex] [ or x = 3.5 ]
A cat casts a 32-inch shadow at the same time a nearby flower casts an 8-
inch shadow. If the flower is 3 inches tall, how tall is the cat?
Answer:
the cat is 27 inches tall
Step-by-step explanation:
the cat is 27 inches tall because when the flower cast is 8 inches but the flower itself is 3 inches you do 8-3=5 take 32-5 and you get 27inches
The customer must first pay an annual 300 a ductile in the policy covers 70% of cost of x-rays the first Insurance claim for Pacific year submitted by a person or two X-Rays the first x-ray cost 6:40 and the secondary x-ray cost 950 how much in total will he need to pay for these x-rays
Answer:
$177
Step-by-step explanation:
Given that:
Percentage covered by policy = 70%
Hence, person needs to pay (100 - 70)% = 30%
X - Ray cost :
1st = 640
2nd = 950
Total cost = (640 + 950) = 1590
Amount the person has to pay:
Total cost * 30%
1590 * 0.3 = $477
Since the person has $300 deductible :
$477 - $300 = $177

Write down in terms of n, an expression for the nth term of the following sequences: a) 1 8 15 22 29 B) 12 16 20 24 28
A)
Sequence: 1 , 8 , 15 , 22 , 29
Difference : 7

A sequence is an ordered list of elements with a specific pattern.
The nth term of the sequence:
A) 1 8 15 22 29 is [tex](n-1)^{th}[/tex] + 7.
B) 12 16 20 24 28 is [tex](n-1)^{th}[/tex] + 4.
What is a sequence?A sequence is an ordered list of elements with a specific pattern.
Example: 2, 5, 8, 11, ... is a sequence where each term is obtained by adding 3 to its previous term.
We have,
a) 1 8 15 22 29
1 + 7 = 8
8 + 7 = 15
15 + 7 = 22
22 + 7 = 29
We see that each term is obtained by adding 7 to the previous term
So, the nth will be in the form:
nth = [tex](n-1)^{th}[/tex] + 7
b) 12 16 20 24 28
12 + 4 = 16
16 + 4 = 20
20 + 4 = 24
2 + 4 = 28
We see that each term is obtained by adding 4 to the previous term.
So, the nth term will be in the form:
nth = [tex](n-1)^{th}[/tex] + 4
Thus the nth term of the sequence:
1 8 15 22 29 is [tex](n-1)^{th}[/tex] + 7.
12 16 20 24 28 is [tex](n-1)^{th}[/tex] + 4.

floors and then down 9 floors.
What floor is it on?
Answer:
Two floors underground

Which best represents the solution set of all real numbers?
[ [ PLEASE ANSWER , I'M CONFUSED ] ]
Answer:
B.
Step-by-step explanation:
Since the solution set is all real numbers, our solution graph must cover the entire number line.
We can see that B contains the graph that extends infinitely in both directions, thereby covering the entire number line.
Therefore, our answer is B.
A is not correct because it leaves out [-6, 1] (approximately).
C is not correct because it leaves out everything to the left of -7 and everything to the right of 1.

Enter the equation in slope-intercept form. Then graph the line described by the equation.
5x + y = 1
Slope-intercept form is (select)
5x +y = 1
Answer:
y = 1 -5x
Step-by-step explanation:
You have to get y by itself. So first you move 5x to the other side but since it’s positive you have to make it negative so it canceled out.
Hi there!
[tex]\large\boxed{y = -5x + 1}[/tex]
5x + y = 1
Arrange into slope-intercept form (y = mx + b):
Subtract both sides by -5x to isolate y:
5x - 5x + y = 1 - 5x
y = 1 - 5x
Rearrange:
y = -5x + 1
Graph the equation by finding corresponding x and y values:
X Y
