Plz help me! Find the perimeter of the shape
Answers and the shape are in the picture
I believe the answer would be 12.4 the first choice.
Answer:
=12.4 units
Step-by-step explanation:
We can use the Pythagoras theorem to find the lengths of EF, FG, and HE
(GF)²=(ΔX)²+(Δy)²
(GF)²=(2--1)²+(4-3)²
=3²+1²
=10
GF=√10=3.16 units
(EF)²=(Δx)²+(Δy)²
=(2--1)²+(6-4)²
=3²+2²
=9+4
=13
EF=√13=3.61 units
(HE)²=(Δx)²+(Δy)²
=(-1--3)²+(6-3)²
=2²+3²
=4+9
=13
HE=√13=3.61 units
GH=(-1--3)=2 units
Perimeter =GF+EF+EH+HG
=3.16+3.61+3.61+2
=12.38 units

Given that h=10, b=5, and r=3.8, find the area of the unshaded region. Use 3.14 for π as necessary. All answers are expressed in square units.
A. 70.34

C. 25
D. 20.34
The area of the circle is found using the formula Area = PI x r^2
The area of a triangle is found using the formula Area = 1/2 x base x height.
Using the given dimensions:
Area of the circle = 3.14 x 3.8^2 = 45.3416 square units.
The area of the triangle is 1/2 x 5 x 10 = 25 square units.
To find the area of the unshaded part, subtract the area of the shaded triangle from the circle:
Area = 45.3416 - 25 = 20.3416
Round to two decimal places = 20.34
The answer is D. 20.34
D. 20.34
In this case, we must calculate first the Areas of the Triangle ([tex]A_{t}[/tex]), in square units, and the Circle ([tex]A_{c}[/tex]), in square units, later we subtract the Area of the former from the Area of the latter to determine the Area of unshaded region ([tex]A_{u}[/tex]), in square units. The Area formulas for each figure are, respectively:
Triangle
[tex]A_{t} = \frac{1}{2}\cdot b\cdot h[/tex] (1)
Circle
[tex]A_{c} = \pi\cdot r^{2}[/tex] (2)
Unshaded Area
[tex]A_{u} = A_{c} - A_{t}[/tex] (3)
Where:
[tex]h[/tex] - Height of the triangle.
[tex]b[/tex] - Base of the triangle.
[tex]r[/tex] - Radius of the circle.
If we know that [tex]h = 10[/tex], [tex]b = 5[/tex] and [tex]r = 3.8[/tex], then the area of the unshaded region is:
[tex]A_{t} = \frac{1}{2}\cdot (5)\cdot (10)[/tex]
[tex]A_{t} = 25[/tex]
[tex]A_{c} = \pi\cdot 3.8^{2}[/tex]
[tex]A_{c} \approx 45.365[/tex]
[tex]A_{u} = 45.365-25[/tex]
[tex]A_{u} = 20.365[/tex]
The correct answer is D.

A bag of marbles contains 3 yellow marbles, 4 blue marbles, and 8 red marbles. Which of the following is true of selecting a marble that is a primary color (red, yellow, or blue)? Select all that apply.
The probability is
This event is certain to happen.
This event will not happen.
The probability is 1.
The probability is 0.
Answer:
the probability is the event is certain to happen
Step-by-step explanation:
Answer:
This event is certain to happen.
The probability is 1.
Step-by-step explanation:
Probability theory aims to explain the chance of an event occurring. In this case, there are 3 yellow balls, 4 blue balls and 8 red balls. The total of balls will be 3 + 4 + 8 = 15
If a random ball is removed, it can be any of three colors. The color that has the most balls will have a higher chance of being chosen from the 15 totals.
Likelihood of drawing a red ball: 8/15
Probability of a yellow ball: 3/15
Blue ball probability: 4/15
The question explains that only one ball will be removed and explains that there are only 3 colors. Therefore, when removing a ball, it will certainly be one of three colors.
This can be confirmed by adding the probability of each ball: 8/15 + 3/15 + 4/15 = 15/15 = 1
Thus, if a primary ball is removed, it will certainly be one of three colors. Moreover we can say that chance of being red is greater than being blue, which is greater than being yellow.
The point (-3,-2) is rotated 180 degrees about the origin. The coordinates of its image are:
Answer:
(3,2)
Explanation:
The rotation of a point 180 degrees about the origin follows the rule:
(x,y) → (-x, -y)That means that both the x-coordinate and the y-coordinate transform into their negative values.
So, - 3 transforms into - (-3) = 3, and - 2 transforms into - (-2) = 2.
The result is (-3, -2) → (3,2).

There is a pie eating contest with 9participants. There are 46 pies that are all eaten. Which of the following best describes how many pies each person ate if they are very evenly matched?
To determine the average number of pies eaten by each participant in a contest with 9 participants and 46 pies, divide the total pies by the total participants. The result is approximately 5.11 pies per person, indicating they ate very evenly with most having eaten about 5 pies.
The question asks us to find out how many pies each person ate in a pie eating contest with 9 participants and 46 pies consumed. To calculate this, we divide the total number of pies by the number of participants. Here's the calculation:
Divide 46 pies by 9 participants to get the average number of pies per person.
The result is approximately 5.11 pies per person.
Since we can't have a fraction of a pie eaten in a real context, it suggests that participants ate either 5 or 6 pies each, if they are very evenly matched.
Therefore, the best description of how many pies each person ate, assuming they are very evenly matched, would be approximately 5 pies per person, with some participants possibly having eaten 6 pies to account for the total of 46 pies.

Step-by-step explanation:
Percentages are always calculated by multiplying the percentages with 100. Like in this example, 50% means 0.5. This 0.5 was multiplied before by 100 to get this percentage. So to find out the equivalent forms, we would simplify the percentage like:
50%-------> 0.5
10%--------> 0.1
75%--------> 0.75

0.5 means 1/2 of the total value
0.1 means 1/10 of the total value
0.75 means 3/4 of the total value.

Find the measure of
Answer:
41.04 meters
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other the given angle is the included angle. The initial position is given by A. The tree is denoted as C and the fence post is denoted as B. Since the use of sine rule will complicate the question, it will be easier to solve this question using the cosine rule. Therefore, cosine rule will be used to calculate the length of BC. The cosine rule is:
BC^2 = AB^2 + AC^2 - 2*AB*AC*cos(BAC).
The question specifies that AC = 70 meters, BAC = 25°, and AB = 35 meters. Plugging in the values:
BC^2 = 35^2 + 70^2 - 2(35)(70)*cos(25°).
Simplifying gives:
BC^2 = 1684.091844.
Taking square root on the both sides gives BC = 41.04 meters (rounded to two decimal places).
Therefore, the distance between the point on the tree to the point on the fence post is 41.04 meters!!!

The coordinates of △ABC are A(−11,7), B(−5,−3), C(−2,3). After a dilation, the coordinates are A'(22,−14), B'(10,6), C'(4,−6). Find the scale factor.
Answer:
-2
Step-by-step explanation:
Before a dilation you have the point (x,y).
After a dilation of a scale factor of r you have (r*x,r*y).
Let's look at one pair of corresponding points.
A(-11,7) and A'(22,-14)
We need to figure out what we can multiply to -11 to get 22.
We need to figure out what we can multiply to 7 to get -14.
Hopefully it is the same number or this isn't a dilation.
So to get from pre-image to image you need to multiply by -2 because -11*-2=22 and 7*-2=-14.
The scale factor is -2.
The dilation is this: (x,y)->(-2x,-2y)
The required scale factor is -2
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures.
How to find the scale factor? We know that if we have the point (x, y) before a dilation and (ax, ay) after a dilation, then a is the scale factorLet's consider one pair of corresponding points.
A(-11,7) and A'(22,-14)To get the scale factor we need to find out what we can multiply to -11 and 7 to get 22 and -14Clearly we need to multiply by -2.
This is applicable for all the points
So, the scale factor is -2.

How many multiples of three are between 10 and 787 and show work pls
As per the concept of arithmetic sequence, there are 259 multiples of three between 10 and 787
To solve this problem, we need to find the first and last multiples of three within the given range and then count how many integers are there in between
Step 1: Find the first multiple of three greater than or equal to 10.
The first multiple of three greater than or equal to 10 is 12.
Step 2: Find the last multiple of three that is less than or equal to 787.
The largest multiple of three less than or equal to 787 can be calculated as follows:
Divide 787 by 3:
787 ÷ 3 ≈ 262.33
The largest multiple of three less than or equal to 787 is:
262 × 3 = 786
Step 3: Count the multiples of three within the range.
Now that we have found the first and last multiples of three within the range, we need to count the number of multiples of three between them, including the endpoints.
The multiples of three between 12 and 786 are:
12, 15, 18, ..., 783, 786.
Step 4: Calculate the total count of multiples.
To calculate the total count, we can use the formula for finding the number of terms in an arithmetic sequence:
Number of terms = (last term - first term) / common difference + 1.
In this case, the first term is 12, the last term is 786, and the common difference (the difference between consecutive terms) is 3.
Number of terms = (786 - 12) / 3 + 1
Number of terms = 774 / 3 + 1
Number of terms = 258 + 1
Number of terms = 259.

Why is this the graph of the function f(x)=4x^2-8x+7?
Answer:
I'll be referring to this form: ax^2-bx+c
The 4x^2 is the rate that it goes up. If a is greater than 1, then that means the graph gets narrower from the parent function x^2. You can clearly see that in that graph.
The c is always the y-intercept. In this case, you can see that it's 7. The graph clearly shows 7 as it's y-intercept as well, so that matches well.
Sadly, I do not know how to compare the 8x into this situation without a calculator, but that information should be quite enough to see how that function is in that graph.

To solve the system of linear equations by graphing, we'll plot the two equations on the same set of axes and find the point of intersection, which represents the solution.
Start with the first equation, y = -x - 7. Choose a few x-values, calculate the corresponding y-values, and plot the points on the graph.For the second equation, x + 2y = 4, rewrite it in slope-intercept form (y = mx + b) by solving for y: 2y = -x + 4 → y = -0.5x + 2. Plot points using this equation.The point where the two graphs intersect is the solution. Confirm that the coordinates of this point satisfy both equations.The solution is (3, 0.5). Confirming for the first equation: y = -3 - 7 = -10 and for the second equation: 3 + 2(0.5) = 4. The coordinates match both equations.

find sec theta if theta is in quadrant 4 and sin theta= -1/5
Answer:
[tex]\frac{5}{2\sqrt{6} }[/tex]
Step-by-step explanation:
Since Θ is in fourth quadrant then cosΘ > 0, as is secΘ
Given
sinΘ = - [tex]\frac{1}{5}[/tex], then
cosΘ = [tex]\sqrt{1-(-1/5)^2}[/tex]
= [tex]\sqrt{1-\frac{1}{25} }[/tex] = [tex]\sqrt{\frac{24}{25} }[/tex] = [tex]\frac{2\sqrt{6} }{5}[/tex]
Hence
secΘ = [tex]\frac{1}{\frac{2\sqrt{6} }{5} }[/tex] = [tex]\frac{5}{2\sqrt{6} }[/tex]
Answer:
[tex]\sec(\theta)=\frac{5\sqrt{6}}{12}[/tex]
The answer is the last one.
Step-by-step explanation:
If we are in quadrant 4, then x (cosine) is positive and y (sine) is negative.
Since cosine is positive, secant is positive because secant is the reciprocal of cosine.
So we already know the answer is not the 1st one or the 3rd one.
I'm going to use a Pythagorean Identity to find cosine value of theta.
[tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex]
Enter in -1/5 for [tex]\sin(\theta)[/tex]:
[tex]\cos^2(\theta)+(\frac{-1}{5})^2=1[/tex]
Simplify a bit:
[tex]\cos^2(\theta)+\frac{1}{25}=1[/tex]
Subtract 1/25 on both sides:
[tex]\cos^2(\theta)=1-\frac{1}{25}[/tex]
Write 1 as 25/25 so you have a common denominator on the right hand side:
[tex]\cos^2(\theta)=\frac{25}{25}-\frac{1}{25}[/tex]
[tex]\cos^2(\theta)=\frac{24}{25}[/tex]
Take the square root of both sides:
[tex]\cos(\theta)=\pm \sqrt{\frac{24}{25}}[/tex]
[tex]\cos(\theta)=\pm \frac{\sqrt{24}}{\sqrt{25}}[/tex]
I will worry about simplifying the square root part when finding secant.
We said that cosine was positive because we were in the fourth quadrant.
[tex]\cos(\theta)=\frac{\sqrt{24}}{\sqrt{25}}[/tex]
Now recall that cosine and secant are reciprocals of each other:
[tex]\sec(\theta)=\frac{\sqrt{25}}{\sqrt{24}}[/tex]
Let's simplify the square part not.
Usually people hate the square root on both and also if you look at your choices none of the choice have square root on bottom.
So we are going to multiply top and bottom by [tex]\sqrt{24}[/tex]. I'm going to also write 5 instead of [tex]\sqrt{25}[/tex].
[tex]\sec(\theta)=\frac{5}{\sqrt{24}} \cdot \frac{\sqrt{24}}{\sqrt{24}}[/tex]
[tex]\sec(\theta)=\frac{5\sqrt{24}}{24}[/tex]
Now let's simplify the square root of 24.
We know 24 is not a perfect square, but 24 does contain a factor that is a perfect square. That factor is 4.
[tex]\sec(\theta)=\frac{5\sqrt{4}\sqrt{6}}{24}[/tex].
[tex]\sec(\theta)=\frac{5(2)\sqrt{6}}{24}[/tex]
[tex]\sec(\theta)=\frac{10\sqrt{6}}{24}[/tex]
Now both 10 and 24 share a common factor of 2 so let's divide top and bottom by 2:
[tex]\sec(\theta)=\frac{5\sqrt{6}}{12}[/tex]

situation 1 : flat rate of 50....1.50 per movie.....after 1 month her bill is 66.25
66.25 = 1.50x + 50
situation 2 : flat rate of 60....1.25 for every movie...
y = 1.25x + 60
both situations have a flat rate fee plus a charge for every movie. In situation 1, u can solve for x (the number of movies rented) because u know how much she was charged. However, in situation 2, without more information, u cannot solve this equation...what u would need to solve it would either be the number of movies rented or the total bill showing what she was charged. So basically, in situation 1, u are given more information then in situation 2.....enough information to be able to solve for the variable x...whereas, in situation 2, u are not given enough info to solve for a variable and get a numerical answer
BRAINLIEST PLEASE!!!!!
Answer: Situation 1 involves one independent variable that stands for the number of movies Melinda rented. Situation 1 gives a total for the monthly bill, but situation 2 does not give a total for the monthly bill. Because situation 2 leaves the total value out, it needs an additional variable. Therefore, situation 2 involves two variables—the number of movies Kimberly rented (the independent variable) and the monthly cable bill (the dependent variable). In this situation, we can’t solve for one variable without knowing the other.

Find the volume of a cylinder that has a radius of 7 and a height of 18.
Answer:
V≈2770.88
Step-by-step explanation:
The volume of a cylinder that has a radius of 7 and a height of 18 is 2770.88.
In order to find the answer, you should use the formula πr²h.
R means radius and H means Height.
V=πr2h=π·72·18≈2770.88472
Answer:
V = 882pi units^3
or approximately
2769.48 units^3
Step-by-step explanation:
The column of a cylinder is given by
V = pi * r^2 * h
We know the radius is 7 and the height is 18
V = pi * 7^2 *18
V =pi *49 *18
V =882 pi
If we want an approximate answer, we can approximate pi by 3.14
V = 3.14 * 882
V =2769.48
