Answer:
(3, -1)
Step-by-step explanation:
Let A be the midpoint and (x,y) its coordinates
● x = (2 + 4)/2 = 6/2 = 3
● y = (5 +(-7))/2 = -2/2 = -1
So the coordinates are (3, -1)
Which ordered pair is a solution of y = 4x? a. (3, 10) b. (-5, -20) c. (-20, -5) d. (1.5, 6)
Answer:
YOUR CORRECT OPTION IS B
B) (-5,-20)
y=4x
x= -5
y= -20
Putting values
-20 = 4(-5)
= -20 = -20
Thus, the correct answer is B
Answer:
b (-5,-20)
Step-by-step explanation:
the first number in an ordered pair is the x value and the second is y so when you substitute in these values you get -20= 4(-5) which is true

A football match started by 10.25am and ended by 1.35pm. how long did it last?
Answer:
The match last for 3 hours and 10 minutes.
Step-by-step explanation:
Match started at 10.25 am
Match ended at 1.35 pm
We need to find how long did the match last.
Minutes between 10.25 am to 11 am = 35 minutes
Minutes between 1 pm to 1.35 pm = 35 minutes
Time between 11 am to 1 pm = 2 hours
Time between 10.25 am and 1.35 pm is :
T = 2 hours 70 minutes
But 1 hour = 60 minutes
T = 2 hours (60+10) minutes
T = 3 hours 10 minutes
It means the match last for 3 hours and 10 minutes.

(-1,4) is a solution to the equation 3x + 8y =
29, substitute
for x —
and
for y — .
Answer:
(- 1, 4 ) is a solution to the equation
Step-by-step explanation:
Substitute x = - 1 and y = 4 into the left side of the equation and if the value obtained is equal to the right side then it is a solution
Given
3x + 8y = 29, then
3(- 1) + 8(4) = - 3 + 32 = 29 = right side
Thus (- 1, 4 ) is a solution of the equation
Steve needs to ship a box of dice, each of which is a cube with a volume of 1 cubic centimeter. How many dice can Steve fit in this box? A. 39 B. 270 C. 972 D. 1,944
Answer:
D. 1,944
Step-by-step explanation:
the box's size is missing, so I looked for a similar question:
the box measures:
base (12 cm) width (9 cm) height (18 cm)total volume of the box = 12 x 9 x 18 = 1,944 cm³
since each dice occupies a volume of 1 cm³, then you can fit 1,944 dices in each box.

D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Answer:
Rock the House Digital Designs charges $500.00 for the initial consultation with the Johnson family, plus $50.00 for every additional hour of work for the house plans. If they are hired for h hours, the total charge for Rock the House Digital Designs would be:
Total charge for Rock the House Digital Designs = 500 + 50h
Elegant Home Architects charge $75.00 per hour for the house plans, if they work for h hours, the total charge would be:
Total charge for Elegance Home Architects = 75h
A) Option A is not correct since the total charge for Rock the House Digital Designs is 500 + 50h
B) Option B is correct because the total charge for Elegance Home Architects = 75h
C) Option C is not correct, For an initial consultation, the cost for using Rock the House Digital Designs is $500
D) For a period of 15 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(15) = $1250
Total charge for Elegance Home Architects = 75h = 75(15) = $1125
Option D is correct because Elegance home architect would be cheaper
E) For a period of 40 hours:
Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(40) = $2500
Total charge for Elegance Home Architects = 75h = 75(40) = $3000
Option D is correct because Rock the House Digital Designs would be cheaper
Find the difference between 7/10 and 14/15
Answer:
the difference between the two fractions is 1/10
Step-by-step explanation:
when solving this problem you must switch the denominators to the same number. in this case thats 30. so 10*3 is 30 and 15*2 is 30. so then we multiply 7*3 to get 21 and 14*2 to get 24. so now we have 21/30 and 24/30, so then we compare. and we end up with 3/30, we simplify the answer to 1/10.
the area of square is 36 square meters. what is the length (in meters) of one side in the square
Answer:6m
Step-by-step explanation:
Square root 36m²
The required length of the side of the square is 6 meters.
Given that,
the area of the square is 36 square meters, what is the length (in meters) of one side in the square needs to be determined.
A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of the polygon, equilateral triangle, square, pentagon, etc
Here,
Since all the sides of the square are identical and the square is a polygon also.
Area of square = (side)²
we have given the area of a square, i.e. 36
36 = side²
side = √36
side = 6 (since √36 = 6)
Implies length of its side is 6 meters
Thus, the required length of the side of the square is 6 meters.

Help with question on Complementary and Supplementary Angles
Step-by-step explanation:
Right angle = 90°
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90, x = 29.
Supplementary angles = Angles that add up to 180°.
x + (x + 104) = 180
2x = 76, x = 38.
The value of x in fig.1 is 29 .

The life expectancy in the US is 75 with a standard deviation of 7 years. A random sample of 49 individuals is selected. What is the probability that the same mean will be larger than 77 years?
Answer:
0.02275
Step-by-step explanation:
We use this z score formula to solve for this question
z-score is is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
From the above question,
x = 77
μ = 75
σ = 7
number of samples = 49
Hence, the z score = 77 - 75/ (7/√49)
= 2/(7/7)
= 2/1
= 2
Hence, the z score = 2
Using the z table to find probability
P(x<77) = 0.97725
P(x>77) = 1 - P(x<77)
= 1 - 0.97725
= 0.02275
Therefore, the probability that the same mean will be larger than 77 years
is 0.02275

Answer: Choice A
Ray PL and ray PQ
=======================================================
Explanation:
Opposite rays always have the same endpoint in common. So opposite rays start with the same letter.
Opposite rays also lay on the same geometric line. This means they point in complete opposite directions. Gluing together two opposite rays forms a line that extends forever in both directions.
Ray PQ points in one direction while ray PL points in the opposite direction. These are opposite rays.
Saying "ray PQ" is different from saying "ray QP". The order matters. This is because the first letter tells you the endpoint while the second letter is where the ray is aimed at (and where it goes off forever).
what is 3x-15+6x+2=45
Answer:
x=58/9 fraction x=6 4/9
Step-by-step explanation:
Answer:
x = 6.44 (rounded)
Step-by-step explanation:
First, combine like terms:
3x + 6x + 2 - 15 = 45
(3x + 6x) + (2 - 15) = 45
(9x) + (-13) = 45
9x - 13 = 45
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and is:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 13 to both sides:
9x - 13 (+13) = 45 (+13)
9x = 45 + 13
9x = 58
Next, divide 9 from both sides:
(9x)/9 = (58)/9
x = 58/9
x = 6.44
Solve for x.
6(x - 1) = 9(x + 2)
x=-8
O x=-3
O x = 3
O x = 8
