Find the angle represented by x (rounded to the nearest tenth of a degree). A) 32.6° B) 36.4° C) 37.8° D) 38.7°
Answers
Answer:
The angle is 49.63°, approximately.Step-by-step explanation:
In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.
Having these elements, we can use the sine trigonometric reason to find the angle.
\(sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°\)
Therefore, the angle is 49.63°, approximately.

Answer: 66 yd
Explanation: It might seem like a very difficult shape to find the area, but it is actually really simple. All you have to do is split this shape in multiple squares, then find each area of each square, then add up all the square's area to get the total area of the shape.
Notice: Please take a look at the image I included to see how I divided the shape.
Step 1.) Since the shape is in a weird shape that doesn't allow us to find the area by normal means, we will split it in workable shapes. In this case, splitting it in 3 rectangles is best option (see image below).
Step 2.) Find the dimensions of each rectangle you split. Since we have new shapes, let us find the dimensions of each shape now.
Notice: Some sides of the shapes are split in half, to find the total length of a side we just add up the splits of the side. In this example our length's of the Rectangle 1 and 3 where split by 2 and 5 yards.
Rectangle 1: Length: 7yd; Width: 4yd
Rectangle 2: Length: 2yd; Width: 5yd
Rectangle 3: Length: 7yd; Width: 4yd
Step 3.) With the new dimensions of each shape, apply the correct formula for the area of each rectangle to find the area of each rectangle.
Area = Length x Width
A= L x W
Rectangle 1: Area = 28
A = L x W
A = (7) x (4)
A = 28
Rectangle 2: Area = 10
A = L x W
A = (2) x (5)
A = 10
Rectangle 3: Area = 28
A = L x W
A = (7) x (4)
A = 28
Final Step 4.) Now that we have the area of each individual rectangle, let us combine all the areas to find the total area of the shape.
Rectangle 1 + Rectangle 2 + Rectangle 3 = 66
28+10+28 = 66
Note: If you have any questions please let me know. If not, I hope this helped. Your very welcome :-)

Answers
Answer: The answer is D
Step-by-step explanation:
Since there are 20 people in the 53-65 range, we can add that to the number of people in the 14-26 range which is 60.
The sum of both of those then gives us 80 which is the same amount as the 40-52group
Answer:
40-52 & 53-65
Step-by-step explanation:
we know our age groups mean that there can be more than 120 in number as the 27-39 age group can only be 2 groups. Which conceals the fact that we need it two
40-52 is an age group which has 80 in number and below it the
“ 14-28 age group “
60 in age group.
And60+80 is more than the number 27-39 ager group by 20 in number.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answer:
1. D = 48, two; 2. D = -8, none; 3. D = 0, one
4.D = 81, two; 5. D = -91, none; 6. D = 49, two
Step-by-step explanation:
The formula for a quadratic equation is
ax² + bx + c = 0
The quadratic formula gives the roots:
\(x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} = \dfrac{-b\pm\sqrt{D}}{2a}\)
D is the discriminant.
It tells us the number of roots to the equation — the number of times the graph crosses the x-axis.
\(D = \begin{cases}\text{positive} & \quad \text{2 real solutions}\\\text{zero} & \quad \text{1 real solution}\\\text{negative} & \quad \text{0 real solutions}\\\end{cases}\)
It doesn't matter if the graph opens upwards or downwards.
If D > 0, the graph crosses the x-axis at two points.
If D = 0, the graph touches the x-axis at one point.
If D < 0, the graph never reaches the x-axis.
1. x² + 6x - 3 =0
a= 1; b = 6; c= -3
D = b² - 4ac = 6² - 4×1×(-3) = 36 - 4(-3) = 36 + 12 = 48
D > 0: two real solutions
2. 3x² + 2x + 1 = 0
a = 3; b = 2; c =1
D = b² - 4ac = 2² - 4×3×1 = 4 - 12 = -8
D < 0: no real solutions
3. x² + 4x + 4 = 0
a = 1; b = 4; c =1
D = 4² - 4×1×4 = 16 - 16 = 0
D = 0: one real solution
4. 5x² + x = 4
5x² + x - 4 = 0
a = 5; b = 4; c = -4
D = 1² - 4×5×(-4) = 1 - 20(-4) = 1 - (-80) = 1 + 80 = 81
D > 0: two real solutions
5. 5x² - 3x = -5
5x² - 3x + 5= 0
a = 5; b = -3; c = 5
D = (-3)² - 4×5×5 = 9 - 100 = -91
D < 0: no real solutions
6. x² - x = 12
x² - x - 12= 0
a = 1; b = 1; c = -12
D = 1² - 4×1×(-12) = 1 - 4(-12) = 1 + 48 = 49
D > 0: two real solutions

"You figure you can ride Ghost Wind, then get on. Just bring him back to the stable when you're finished so I can rub him down." I dismounted, leaving the stallion with Mitchell, and headed toward the barn. Now, I truly expected that Mitchell would come after me with Ghost Wind. After all, despite my invitation, I knew Mitchell couldn't ride Ghost Wind. As far as I knew, Mitchell had never ridden more than a mule and had no idea how to ride a thoroughbred tornado like Ghost Wind. But instead of Mitchell following me, the next thing I knew, I heard a triumphant cry, turned, and saw Mitchell atop the stallion dashing across the meadow. For a moment all I could do was stand and stare. But then, as the stallion bucked, left the meadow, and headed for the woods, I suddenly found my legs and my voice, and I began running and screaming after Mitchell and the stallion.

Use c for the additional amount (in dollars) Bob will spend.
Write your answer as an inequality solved for c.
Answers
We can express the inequality as follows:
c ≤ $31 - $18
Simplifying the right side:
c ≤ $13
Therefore, the possible additional amounts Bob will spend, represented by "c," are less than or equal to $13. The inequality is c ≤ $13.

A.) 18

C.) 4 1/2

Answer:
I think it 4 1/2

Explanation: Since the recipe is tripled you multiply the 6 by 3 and you get 18. Since the answer is in gallons you have to convert. 4 quarts= 1 gallon. 18 divided by 4 is 4 with a remainder of 2. 2 is a half of 4 so the answer is 4 1/2

Answers
You have
0/0 2/1 4/2 6/3
To find the unit rate, divide the numerator and denominator of 4/2 by the denominator, 2 and you will get 2/1
Also divide the numerator and denominator of 6/3 by the denominator 3, and you will get 2/1.
2/1 = 2/1 = 2/1
So, the unit rate would be 2min/1lap or 2 minutes for every 1 lap.
