Step-by-step explanation:
On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, negative 2), and point K is at (negative 2, negative 3).
HIJK is a parallelogram because the midpoint of both diagonals is __________, which means the diagonals bisect each other.
(1,−1)
(1,1)
(1,0)
(0,1)
============================================================
Explanation:
Point H is at (-2,2) and J is at (4,-2)
Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.
The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.
The midpoint is at (1,0). That's why the answer is choice C.
--------------------------
This next section is optional.
Points I and K are located at (4,3) and (-2,-3) respectively
Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1
Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0
We end up with the same midpoint (1,0)
The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

C is the correct answer

Answer:
Step-by-step explanation:
First, let's find the area of the triangle. The Area of a triangle can be modeled as
b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24
To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16
16pi= approximately 50.24
50.24/2= 25.12
25.12 + 16 = 41.12
The area of the figure is approximately 41.12 ft^2

Answer:
49.12 ft²
Step-by-step explanation:
The compound figure includes both a right angled triangle and a semi-circle. To find the area of the figure, it is best to find the area of both shapes then add them.
Area of semi-circle = (πr²) ÷ 2
= (3.14 × 4 × 4) ÷ 2
= 50.24 ÷ 2
= 25.12 ft²
Area of triangle = [tex]\frac{1}{2}[/tex]bh
= [tex]\frac{1}{2}[/tex] × 6 × 8
= 24 ft²
Area of compound figure = Area of semi-circle + Area of triangle
= 25.12 + 24
= 49.12 ft²

if G is the number of seconds that a traffic light says green and n is the average number of cars in each lane per light cycle, then the relationship would be G= 2.1n + 3.7
if the light stays green for 70 seconds then how many cars can cross the intersection in one cycle?

Answer:
31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.
Step-by-step explanation:

Round 382 to 1 significant figure
Answer:
382=380
Step-by-step explanation:
l don't know the answer but just trying
Rounding to one significant figure is to round the given number into a number where the first digit is a number and the remaining digits are all zeroes.
The number after rounding 382 to 1 significant figure is 400.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,
382
We will round to 1 significant figure.
This means the hundred place value must be the only number remaining while keeping all the place values as zero.
Since the tens place value is more than 4.
We can round the hundred place value 3 into 4.
Now,
382 will be 400 when rounded to 1 significant figure.
Thus,
The number after rounding 382 to 1 significant figure is 400.

Three Bell ringing constituency in intervals of 30,36 and 45 minutes respectively. At what time will they ring together again if they ring simultaneously at 8:00 a.M.
Answer:
The bells will ring simultaneously at 11.00 a.m
Step-by-step explanation:
Firstly, what we have to do here is to get the lowest common multiple the three numbers
The numbers are the given minutes
These are 30,36 and 45 minutes
The lowest common multiple of these three is 180 minutes
Now, we convert this to hours
60 minutes = 1 hour
180 minutes = x hours
x * 60 = 180 * 1
x = 180/60
x = 3 hours
If we added this to 8 am, we have 8 + 3 = 11 a.m
Suppose the mean percentage in Algebra 2B is 70% and the standard deviation
is 8%. What percentage of students receive between a 70% and 94% Enter the
value of the percentage without the percent sign.
HELP PLEASE!!
Answer:
49.87%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 70%
σ is the population standard deviation = 8%
a) For x = 70%
z = 70% - 70%/8%
z = 0
Probability value from Z-Table:
P(x = 70) = 0.5
b) For x = 70%
z = 94% - 70%/8%
z = 3
Probability value from Z-Table:
P(x = 94) = 0.99865
The probability of students that receive between a 70% and 94%
P(x = 94) - P(x = 70)
0.99865 - 0.5
0.49865
Therefore, the percentage of students that receive between a 70% and 94% is
0.49865 × 100
= 49.865%
Approximately = 49.87%

Answer:
29 ; 37
Step-by-step explanation:
The figure is composed by a square, a rectangle, and a right triangle

The perimeter of the rectangle is 10 units
The triangle is composed by a side of 6 units and a side of 5 units
The third side can be find with the Pythagorean theorem

The formula below gives the area of a semi-circle, A, with a radius of r.
Solve the formula for the radius
The area of a semicircle with respect to radius is √2A/π sq. units.
What is a semicircle?A semicircle is half of a circle. It is a 2D shape formed when a circle is cut into two equal parts. We can create two semi-circles from any circle.
The area of a semicircle = π × radius² / 2
So, the area with respect to radius will be =
A = π × radius² / 2
2A = π × radius²
2A / π = radius²
Radius = √2A/π
Hence, the area of a semicircle with respect to radius is √2A/π sq. units.

What is the solution to the equation x/3 = 9 x=
Answer:
x = 27
Step-by-step explanation:
x/3 = 9
Multiply both sides by 3
x/3 * 3 ( the 3's cancel out and we're left with x )
9 * 3 = 27
We're left with x = 27
Answer:
27
Step-by-step explanation:

Step-by-step explanation:
Ariana's rode the bus 5 3/8 miles to the mall
She rode 2 3/4 miles to her friends place
Then she rode anrhe 6 1/12 miles back home
Therefore the total distance can be calculated as follows
= 43/8 +11/4 + 73/12
= 5456/384
= 341/24
= 14 5/24
Hence the total distance is 14 5/24 miles
