what would happen if i hired two private investigators to follow each other...
Answer:
1. The Pacific Ocean has an area of 63.78 million square miles, an average depth of 3,688 meters, and a volume of 660,000,000km cubed.
2. Use these guidelines when developing questions:
Plan your questions.
Know your purpose.
Open conversation.
Speak your listener's language.
Use neutral wording.
Follow general questions with specific ones.
Focus your questions so they ask one thing at a time.
Ask only essential questions.
3. I don't know XD
4. On an adventure that humans don't know about
5. Depends on the picture of the sun.

-
y=-2/3x-4/3
y=-2/3x-10/3
y=-2/3x-2/3
y=-2/3x-17/4
Answer:
C) y= 2/3x -2/3
Step-by-step explanation:
(y-y1)=m(x-x1)
y+2=2/3(x+2)
y+2= 2/3x + 4/3
y= 2/3x -2/3

Answer:
IS a parallelogram
Step-by-step explanation:
The slope formula for the slope of the line between points (x1, y1) and (x2, y2) is ...
m = (y2 -y1)/(x2 -x1)
The distance formula for the length of that same line is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, you're asked to use each of these formulas 4 times, once for each side of the quadrilateral. I find it convenient to let a calculator or spreadsheet do the repetitive calculations. The result is attached.
The attachment shows that opposites sides have the same length and slope, so are parallel. The quadrilateral is a parallelogram. (The two points used in each calculation are the ones on the result line and the line immediately below. That is why point B is copied to the end of the list.)
_____
Additional comments
There are much simpler ways to prove the figure is a parallelogram. My favorite is to add the coordinates of the end points of the diagonals:
B +D = (-2+6, -9-3) = (4, -12)
C +E = (0+4, -5-7) = (4, -12)
These values being the same demonstrates the midpoints of the diagonals are coincident. That will only be the case if the quadrilateral is a parallelogram.
__
If you must use slope and distance formulas, showing either pair of opposite sides is parallel and have the same length is sufficient to guarantee that the other two sides are also parallel and have the same length. That is, the calculations required in this problem only need to be applied to one pair of opposite sides. (Using a spreadsheet, it's not a lot of extra work to do the calculations for both pairs of opposite sides.)

factorise the equation 9x^2 - 4
Answer:
Step-by-step explanation:
a² - b² = (a +b)(a - b)
9x² - 4 = (3x)² - 2²
= (3x + 2 )(3x - 2)
A quadrilateral has the following vertices on a coordinate plane:
================================================
Explanation:
We'll only focus on points J and K.
J = (3, -6)
K = (-1, -6)
Because these two points have the same y coordinate (which is -6), this means we can ignore those values and subtract the x coordinates
3 minus (-1) = 3 - (-1) = 3 + 1 = 4
Or we could plot points J and K on the same xy grid system, and count out the number of spaces between J and K. You should count out 4 spaces.
This means segment JK is 4 units long.

A triangle has two sides of 30 meters and 26 meters, and the angle between them is an obtuse angle. If the area of the triangle is 300 sq. Meters, find the measure of the obtuse angle (to the nearest degree).
Answer:
130°
Step-by-step explanation:
Using the formula
Area of the triangle = 1/2 absin theta
a and b are the sides
theta is the obtuse angle
Given
a = 30m
b = 26m
Area = 200m²
Required
theta
Substitute into the formula;
300 = 1/2(30)*(26)sin theta
300 = 15*26sin theta
300 = 390 sintheta
sin theta = 300/390
sin theta = 10/13
sin theta = 0.7692
theta = arcsin(0.7692)
theta = 50.28degrees
Since the angle is obtuse, it must lie between 90 and 180degrees
theta = 180-50.28
theta = 129.72°
Hence the measure of the obtuse angle to the nearest degree is 130°
Lawrence has $50.
He wants to buy some T-shirts that cost $12 each.
He also wants to have at least $10 left to buy lunch.
Which inequality shows the number of T-shirts, x, Lawrence can buy and still have at least $10 for lunch?
A. x≤3
B.x≥3
C. x≤4
D. x≥4
Answer:
choice A) =<3
Step-by-step explanation:
x = number of shirts
50 -10 = x(12)
40 = 12x
x = 3 .33
Keith mowed his aunt's yard 12 times. Each time, he mowed for 1.75 hours and he earned $8.40 per hour. How much money, to the nearest cent, did Keith earn mowing his aunt's yard?
Answer: $176.40
Step-by-step explanation:
Keith mowed the yard 12 times.
Each time he mowed took 1.75 hours.
The number of hours he took in total is therefore:
= 12 * 1.75 hours
= 21 hours
He gets paid $8.40 for every hour he works. For the 21 hours therefore, he would earn:
= 8.40 * 21 hours
= $176.40

In 1 minute, Alex can type 44 words. While working on a project, Alex types from 10:00 AM until 1 AM, He takes a break from 1 0:25 AM to 10:40 AM. At the same rate, how many words did he type?
Answer:
39600 words
Step-by-step explanation:
Given data
In 1 minute, Alex can type 44 words
from 10:00 AM until 1 AM= 15 hours
15 hours to minutes= 15*60= 900 minutes
Hence in In 1 minute, Alex can type 44 words
in 900 minutes he will type x words
cross multiply
x= 900*44
x= 39600 words
Hence he will type 39600 words

Solve the following system of equations using the substitution method.
The problem- y= -2x+11
3x + y = 18
Answer:
x = 7
y = -3
Step-by-step explanation:
the first equation is already solved for 'y' so we can substitute '-2x+11' for 'y' in second equation
3x + (-2x + 11) = 18
x + 11 = 18
x = 7
solve for 'y'
y = -2(7) + 11
y = -14 + 11
y = -3
Someone plz help me I will give brainliest btw it’s not “decimals”
Answer:
It will not fit.
Step-by-step explanation:
The mat is 1/2 by 2/3. So, lets add that together.
1/2 + 2/3 = 7/6
Now there are 24 sixths in a fourth.
So subtract 24 - 4 = 17
Final answer would be 17/4. Still way to big to fit in the 1/4 step.
Hope this Helps!!:)
