The quotient of 874 and 23 determined using an area model is 38.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have:
= 874 ÷ 23
= (800 + 74 + 4) ÷ 23
We can get the answer by using the area model:
If divide 874 with 23 we get 184 as a remainder and 030 as a quotient
Further, if we divide 184 with 23 we get 0 as a remainder and 008
874 ÷ 23 = 030 + 008 = 38
Thus, the quotient of 874 and 23 determined using an area model is 38.

Graph the function on the coordinate plain
A)what are the x intercepts
B)what is the y intercepts
C)what is the maximum and minimum value
Answer:
it should be C I did something very very similar to this but different questions
Answer:
a) {-6, 2}
b) -12
c) minimum: -16
Step-by-step explanation:
I find a graphing calculator to be a big help. Its graph is attached.
a) The function can be factored as:
f(x) = (x -2)(x +6)
The factors are zero at the x-intercepts: x = 2, x = -6.
b) The y-intercept is the function value when x=0. That is the constant in the function. The y-intercept is -12.
c) The leading coefficient of the function is positive, so its graph opens upward. The extreme value is a minimum. It is found on the axis of symmetry, at the x-value that is halfway between the x-intercepts: x = (2-6)/2 = -2. The function value there is ...
f(-2) = (-2-2)(-2+6) = -4(4) = -16
The minimum is f(-2) = -16.

125
375
Answer:
Mean: 95, Median: 50 Mode: 25
Step-by-step explanation:
1.Mean: add all the numbers then divide by the number of numbers there
25+25+25+25+50+50+125+125+125+375= 950
950 divided by 10 = 95
2.Median :is the number in the middle of all the numbers in this case we have 2 so we will ad those two then divide them by two
50+50=100 100/2 = 50.
3. Mode : this is the most recurring number there and in this case it's 25
Select the graph that matches the equation y = 8

10
x + 9.
Answer:
option C
Step-by-step explanation:
y = mx + b → y = 8.5x + 9
b is the y intercept: 9
m is the slope: 8.5
to identify this on the graph, the y intercept is when x = 0
crossing the vertical bold (y) line
so which one is at 9? c is the only one at 9

The center of the circle will be equal to (-3,4) equation of the circle x²+y²+6x-8y+16=4
What is circle?The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the out trace.
The general form of the equation of the circle is:-
(x-x₁)²+(y-y₁)²=r²
here x1 and y1 are the center of the circle
Now we will convert our equation in the general form:-
x²+y²+6x-8y+16=4
x²+6xy²-8y+16-4=0
x²+3x+3x+9-9+y²-4y-4y+16-16-4=0
(x+3)²+(y-4)²-9-16+16-4=0 (x+3)²+(y-4)²=13

Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side JK
Round your answer to the nearest tenth if necessary.
Answer:
Heyyyy!!
The answer is 66.9
please read the explanation... it will help... I promise
Step-by-step explanation:
Okay... Here we go...
The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...
So... you basically have to find the scale factor...
(the math itself is easier than the explanation...
51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...
so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)

A 90% confidence interval is centered at a _____ and is 90% sure to contain the _______.
a) statistic, variable
b) parameter, statistic
c) statistic, parameter
d) parameter, variable
e) variable, parameter
Answer:
See below
Step-by-step explanation:
A 90% confidence interval is centered at a parameter and is 90% sure to contain the statistic.
When you are running a statistical test, you can create a confidence interval centered at the appropriate parameter (such as the mean) to see if the statistic stated in your null hypothesis is true if it's contained in the interval. Whatever the confidence level is determines how wide the interval will be, and as such, will determine how likely the interval will catch the statistic in question.

From her eye, which stands 1.69 meters above the ground, Sadie measures the angle
of elevation to the top of a prominent skyscraper to be 36º. If she is standing at a
horizontal distance of 275 meters from the base of the skyscraper, what is the height
of the skyscraper? Round your answer to the nearest hundredth of a meter if
necessary.
The height of the skyscraper is 201.5 meters, if the angle of elevation to the top of a prominent skyscraper to be 36º
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
Angle of elevation = 36 degree
Horizontal distance of 275 meters from the base of the skyscraper
From the tan ratio:
tan36 = x/275
x = 275(tan36)
x = 199.79 meters
The height of the skyscraper = 199.79+ 1.69 = 201.48 ≈ 201.5 meters
Thus, the height of the skyscraper is 201.5 meters if the angle of elevation to the top of a prominent skyscraper to be 36º

Consider parallelogram ABCD below.
Use the information given in the figure to find m of angle B, x, and m of angle BCA.
Answer:
Step-by-step explanation:
1) Opposite angles in a parallelogram are congruent, so angle B measures 82 degrees.
2) Opposite sides of a parallelogram are congruent, so 12=6x. Hence, x=2.
3) Opposite sides of a parallelogram are congruent, so by the alternate interior angles theorem, the answer is 62 degrees.
Answer:
see explanation
Step-by-step explanation:
the opposite angles of a parallelogram are congruent , then
∠ B = ∠ D = 82°
the opposite sides of a parallelogram are parallel and congruent , then
AD = BC , that is
6x = 12 ( divide both sides by 6 )
x = 2
∠ BCA and ∠ DAC are alternate angles and are congruent , then
∠ BCA = ∠ DAC = 62°
