YOO PLZ HELP ASAP!!! MARKING BRAINIEST!!! Use the Internet to find the actual area of Ohio. Then find the actual population density of Ohio. How does this compare with your estimate? Why was your initial estimate greater or less than the actual population density?
Answer:
The actual area is 44,825 mi², and the actual population density of Ohio is 282.3 people per square mile. I can't answer the estimate part because I don't know what your estimate was. But you can say my estimate was greater than the actual number or less than the actual number. And you can say your estimate was greater/less than the actual population density because I didn't know so many people were in each square mile because a square mile isn't that large.

Answer:
1.1783
Step-by-step explanation:
The attached picture shows a cross section of the cylindrical shell that it is convenient to use as a differential of the volume. The radius from the center of revolution is (1-x), so the circumference of the shell is 2π(1-x). Of course, its height is tan(x), so the differential of volume is ...
dV = 2π(1-x)tan(x)
The indefinite integral does not have a nice closed-form solution, but it can be easily integrated numerically from x = 0 to 1 by most scientific and graphing calculators. The attached shows the volume to be about 1.1783 cubic units.
Fraiser drew a model of his hometown on the coordinate plane below. Each unit of the coordinate plane represents 1 mile. A grocery store is located at (6, 4) and a school is located at (6, 8). What is the distance between the grocery store and the school?
Answer:
The distance between the grocery store and the school is 4 miles.
Step-by-step explanation:
Given that each point is represented in rectangular form. The staight-line distance ([tex]d[/tex]) between two points on a plane is given by the Pythagorean Theorem:
[tex]d =SF\cdot \sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}}[/tex]
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Horizontal locations of points A and B, dimensionless.
[tex]y_{A}[/tex], [tex]y_{B}[/tex] - Vertical locations of points A and B, dimensionless.
[tex]SF[/tex] - Scale factor, measured in miles.
If [tex]SF = 1\,mi[/tex], [tex]A = (6, 4)[/tex] and [tex]B = (6,8)[/tex], the straight line distance is:
[tex]d = (1\,mi)\cdot \sqrt{(6-6)^{2}+(8-4)^{2}}[/tex]
[tex]d = 4\,mi[/tex]
The distance between the grocery store and the school is 4 miles.

A candy store makes a 12-lb mixture of gummy bears, jelly beans, and Runts. The cost of gummy bears is $1.50 per pound, jelly beans cost $1.00 per pound, and Runts cost $1.00 per pound. The mixture calls for three times as many gummy bears as jelly beans. The total cost of the mixture is $15.00. How much of each ingredient did the store use?
Answer:
g= 6
j = 2
r= 4
Step-by-step explanation:
Gummy bears = $1.50 per pound
Jelly beans = $1.00 per pound
Runt = $1.00 per pound
Total cost of the mixture = $15.00
Let
g = quantity of gummy bears
j = quantity of jelly beans
r = quantity of runts
g + j + r=12 (1)
1.5g + 1.0j + 1.0r = 15 (2)
three times as many gummy bears as jelly beans.
g=3j
Substitute g=3j into 1
g + j + r = 12
3j + j + r =12
4j + r =12 (3)
Substitute g=3j into 2
1.5g + 1.0j + 1.0r = 15
1.5(3j) + 1.0j + 1.0r =15
4.5j + 1.0j + 1.0r = 15
5.5j + 1.0r =15 (4)
4j + r =12 (3)
5.5j + 1.0r =15 (4)
Subtract (3) from (4)
5.5j - 4j = 15-12
1.5j = 3
Divide both sides by 1.5
j = 3/1.5
= 2
j = 2
Substitute j = 2 into (3)
4j + r =12
4(2) + r =12
8 + r = 12
r= 12-8
r= 4
Substitute j=2 and r= 4 into (1)
g + j + r=12
g + 2 + 4 = 12
g + 6 = 12
g = 12-6
=6
g=6
g= 6
j = 2
r= 4
Solve the equation

Use trig ratios to find the measure of the angle in this Triangle (Image)
Answer:
θ = 36.9°
Step-by-step explanation:
Trigonometric ratios in a right triangle will be,
Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{AC}}{\text{AB}}[/tex]
Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{BC}}{\text{AB}}[/tex]
Tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex] = [tex]\frac{\text{AC}}{\text{BC}}[/tex]
In the picture attached,
Given sides are,
AB = 5 and BC = 4
Therefore, to find the given angle θ only Cosine will be applicable.
Cos θ = [tex]\frac{\text{BC}}{\text{AB}}[/tex]
= [tex]\frac{4}{5}[/tex]
θ = [tex]Cos^{-1}(0.8)[/tex]
θ = 36.87°
θ ≈ 36.9°

Answer:
x = 122
Step-by-step explanation:
Step 1: State what is known
In the picture we can see they marked ∠ABC with a box meaning it is a 90° angle, given that information we can now solve
Step 2: Solve
∠ABC = x - 32
90 = x - 32
90 + 32 = x
122 = x
Therefore 'x' is equal to 122
Find the measure of Angle R if a = 9 square root 2 and b = 18 square root 2.
Please help!!
Answer: ∠TRa = 30°, ∠aRA = 90°, ∠TRA = 120°
Step-by-step explanation:
I'm not sure if you need the angle of the left triangle only (= 30°)
or if you need the the triangle plus the rectangle (= 120°)
Left Triangle (∠TRa)
The hypotenuse is twice the base so it is a 30° - 60° - 90° triangle
where the base corresponds to the 30° angle.
Rectangle (∠aRA)
A rectangle has four right angles --> four 90° angles.
Angle Sum Theorem
∠TRA = ∠TRa + ∠aRA
= 30° + 90°
= 120°

Find the value of m. A. 32 B. 63 C. 50 D. 74
Answer:
A
Step-by-step explanation:
Tangents drawn to a circle from an external point are congruent, thus
the triangle formed by the 2 tangents is isosceles with base angles of 74°
m = 180° - (74 + 74)° = 180° - 148° = 32° ( sum of angles in Δ )
The value of the measured angle of m is 32°.
What is a Tangent of Circle?A tangent of a circle is defined as a single point where a single straight line touches or intersects the circle. A line that never touches the inside of the circle is called a tangent.
The line connecting the outer point will cut the angle between the tangents in bisect and the center are equal to each other.
According to the given figure as
A circle with center O,
Since there are two tangents to the circle drawn from an external point.
therefore the lengths of tangents drawn from an external point to a circle are equal.
So, the triangle formed by the 2 tangents is isosceles with base angles of 74°
We know that sum of angles in the triangle is 180 degrees
So ∠ m = 180° - (74 + 74)°
⇒ ∠ m = 180° - 148°
⇒ ∠ m = 32°
Hence, the value of the measured angle of m is 32°.

4x + 9x + 3 = WILL GIVE BRAINLY, PLUS 20 POINTS.
Answer:
13x + 3
Step-by-step explanation:
Since there is no value on the left, you just have to simplify this. You always add similar variables together, and the constant is a different value, so 4x + 9x would result in 13x. 13x + 3 would be the correct simplified answer.
Answer:
13x+3
Step-by-step explanation:
4x+9x+3
You do not add 13x to 3 because 3 does not have an x
Write a function g whose graph represents a reflection in the x-axis of the graph of f(x)=1/2x-3
Answer: g(x) = -(1/2)*x + 3.
Step-by-step explanation:
First, let's define a reflection over the x-axis.
If we have a point (x, y) and we reflect it over the x-axis, our new point will be (x, -y).
Now, when we have a function
f(x) = y, the points can be written as:
(x, y = f(x) ) = (x, f(x))
Then, after the reflection over the x-axis, we have:
(x, y = g(x)) = (x, -f(x))
So now we have g(x) = -f(x)
and we know that f(x) = (1/2)*x - 3
then our new function is g(x) = y = -f(x) = -( (1/2)*x - 3) = -(1/2)*x + 3.
g(x) = -(1/2)*x + 3.
name a pair of corresponding angles
name a pair of alternate interior angles
name a pair of alternate exterior angles
name a pair of same-side interior angles
They are on the same side of the transversal cut (both to the left of the transversal) and they are both above the two black lines. It might help to make those two black lines to be parallel, though this is optional.
Other pairs of corresponding angles could be:
angle 2 and angle 6angle 3 and angle 7angle 4 and angle 8=======================================================
Alternate interior angles = angle 3 and angle 5They are between the black lines, so they are interior angles. They are on alternate sides of the blue transversal, making them alternate interior angles.
The other pair of alternate interior angles is angle 4 and angle 6.
=======================================================
Alternate exterior angles = angle 1 and angle 7Similar to alternate interior angles, but now we're outside the black lines. The other pair of alternate exterior angles is angle 2 and angle 8
=======================================================
Same-side interior angles = angle 3 and angle 6The other pair of same-side interior angles is angle 4 and angle 5. They are interior angles, and they are on the same side of the transversal.
The diameter of a car wheel is 60 cm, if the car travels at an average speed of 13.2m/s, find the number of revolutions made by the car per hour , hiving the awnser correct to nearest whole number. (take pie to be 3.142 )
The wheel has diameter 60 cm = 0.60 m, and thus circumference π(0.60 m) ≈ 5.923 m.
In one complete revolution, a point on the edge of the wheel covers this distance, so that the wheel has an angular speed of
(13.2 m/s) * (1/5.923 rev/m) ≈ 2.229 rev/s
There are 60 seconds to each minute, and 60 minutes to each hour, so converting to rev/h gives
(2.229 rev/s) * (60 s/min) * (60 min/h) ≈ 8024 rev/h
