Answer:
(-1, 3)
Step-by-step explanation:
replace the occurrences of y in the equation
(x + y = 2) with x + 4
x + x + 4 = 2
2x + 4 = 2
solving for x in the first equation
2x = 2 - 4
2x = -2
2x/2 = -2/2
x = -1
replacing all occurrences of x in y = x + 4 with -1
y = (-1) + 4
y = 3
therefore the pairs are (-1, 3)

What is the missing constant term in the perfect square that starts with x^2+\dfrac{1}{2}xx
2
+
2
1
xx, squared, plus, start fraction, 1, divided by, 2, end fraction, x ?
Answer:
1/16
Step-by-step explanation:
Given the expression;
[tex]x^2+\dfrac{1}{2}x[/tex]
To find a constant that will make it a perfect square, we will use the square if the half of coefficient of x
Coefficient of x = 1/2
half of Coefficient of x = 1/2*(1/2)
Half of Coefficient of x = 1/4
square of the half of coefficient of x = (1/4)^2
square if the half of coefficient of x = 1/16
hence the constant that will make it a perfect square is 1/16

Maria wants to know what time it is, but after looking at her analog clock, notices that the numbers are all missing! She notices that the minute hand is pointing straight up, and that the angle measure between the hour and minute hand is 90 degrees. If she knows that the time must be between 1:00 and 5:30, what time is it?
Answer:
3:00
Step-by-step explanation:
If the minute hand is pointing straight up, it means that the time is at an exact hour (ex. 1:00, 2:00, not 1:30, etc.).
If the angle between the hour and the minute hand is 90 degrees, then we know that the time is either 3:00 or 9:00.
However, because the time must be between 1:00 and 5:30, it must be 3:00.

You place four orders for 50 tennis rackets which cost $65 per racket you receive all 200 rackets there is a delivery charge of $15 per order what is your average cost per racket including delivery charges
Answer:
65.30
Step-by-step explanation:
1. 50x4=200
2. 200x65=13,000
3. 13,000 + (15x4)
4. 15 x 4 = 60
5. 13,000 + 60
6. 13,060/200 = 65.3
Your average cost per racket including delivery charges is $65.30.
First step is to calculate the cost of 200 rackets
Cost of 200 rackets= 200 ×$65
Cost of 200 rackets= $13,000
Second step is to calculate the total delivery fee
Total Delivery fee= 15 × 4
Total Delivery fee=$60
Third step is to calculate the total cost including delivery cost
Total cost including delivery cost=$13,000 + $60
Total cost including delivery cos = $13,060
Fourth step is to calculate the Average cost
Average cost per rackets=$13,060/200
Average cost per rackets=$65.30
Inconclusion the average cost per racket including delivery charges is $65.30.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.410.410, point, 4 years; the standard deviation is 1.91.91, point, 9 years.
Use the empirical rule (68-95-99.7\%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a meerkat living less than 16.116.116, point, 1 years.
Answer:
99.85%
Step-by-step explanation:
The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years; the standard deviation is 1.9 years.
Use the empirical rule (68-95-99.7%) to estimate the probability of a meerkat living less than 16.1 years.
Solution:
The empirical rule states that for a normal distribution most of the data fall within three standard deviations (σ) of the mean (µ). That is 68% of the data falls within the first standard deviation (µ ± σ), 95% falls within the first two standard deviations (µ ± 2σ), and 99.7% falls within the first three standard deviations (µ ± 3σ).
Therefore:
68% falls within (10.4 ± 1.9). 68% falls within 8.5 years to 12.3 years
95% falls within (10.4 ± 2*1.9). 95% falls within 6.6 years to 14.2 years
99.7% falls within (10.4 ± 3*1.9). 68% falls within 4.7 years to 16.1 years
Probability of a meerkat living less than 16.1 years = 100% - (100% - 99.7%)/2 = 100% - 0.15% = 99.85%

A store sold 655 bicycles last year. This year the store sold 582 bicycles. What is the percent of change in the number of bicycles sold from last year to this year? Round to the nearest percent
Answer:
12.5%
Step-by-step explanation:
Given data
Number of bicycles sold last year= 655
Number of bicycles sold this year= 582
%percent change= Iniitial -FInal/initial *100
%percent change= 655-582/582*100
%percent change= 73/582 *100
%percent change=0.125 *100
%percent change=12.5%
Hence the percent change is 12.5%

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 30 feet and a height of 16 feet. Container B has a diameter of 22 feet and a height of 20 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full. To the nearest tenth, what is the percent of Container A that is full after the pumping is complete?
Answer:
32.8%
Step-by-step explanation:
Container A:
Diameter = 30 feet
Radius = diameter/2 = 30/2
= 15 feet
Height = 16 feet
Volume of a cylinder = πr²h
= 3.14 * 15² * 16
= 3.14 * 225 * 16
= 11,304 feet ³
Container B:
Diameter = 22 feet
Radius = diameter / 2
= 22/2 = 11 feet
Height = 20 feet
Volume of a cylinder = πr²h
= 3.14 * 11² * 20
= 3.14 * 121 * 20
= 7598.8 feet ³
what is the percent of Container A that is full after the pumping is complete?
Container A - container B
= 11,304 feet ³ - 7598.8 feet ³
= 3,705.2 feet ³
percent of Container A that is full after the pumping is complete = 3,705.2/11,304 × 100
= 0.328 × 100
= 32.8%
percent of Container A that is full after the pumping is complete = 32.8%

PLSS HELP MEEE IVE BEEN TRYING ALL DAY TO GET THIS ANSWER AND NOTHING PLEASE SOMEONE HELP ME NO LINKSS!! Find the midpoint of the segment below and enter its coordinates as an
ordered pair. If necessary, express coordinates as fractions, using the slash
mark for the fraction bar
(-8,-7) (-7,-8)
Answer:
midpoint is (-15/2, -15/2)
Step-by-step explanation:
Finding the coordinates of the midpoint is easy. All you have to do is find the average of the x-coordinates and the average of the y-coordinates of the endpoints of the segment.
So, in your case
(-8 - 7)/2 = -15/2 is the x-coordinate
(-7 - 8)/2 = -15/2 is the y-coordinate
Therefore, the midpoint is (-15/2, -15/2)
Answer:
(-7.5, -7.5)
Step-by-step explanation:
Remember that the formula is (x1+x2/2, y1+y2/2)
So, we know that -8 is x1 and -7 is y1. We also know that -7 is x2 and -8 is y2.
Lets plug this into our formula and see what we get.
(-8+-7/2, -7+-8/2)
Now lets find the x in the midpoint.
-8+-7/2 is equal to -15/2. This makes x equal to -7.5.
Now lets find the y in the midpoint.
-7+-8/2 is equal to -15/2 as well. This makes y equal to -7.5.
Now we can tell that the coordinates for midpoint will be:
(-7.5, -7.5)
MISCONCEPTIONS:
Always remember that midpoint is nothing like slope. The mid point is something you can point on a graph, wheareas slope is a function that can be lined on a graph.
The formulas for the two things are different as well. Slope is y/x, where you subtract the ys and xs from each other. In a way, midpoint is the exact opposite, which is adding the xs and ys together.
I hope this helps ;)
Good luck!
