Find the value of x in the isosceles triangle shown below.
Answer/Step-by-step explanation:
You take one side and use that.
since you split it in half divide the bottom number by 2.
8/2 -> 4
ok now you need to know that since there is 2 angles the same it is a
30-30-60 triangle.
and it goes x,2x, x\(\sqrt[n]{3} \)
you have our 2 sides so then you would just place the x= \(\sqrt{4} \) and simplify it down
so the answer would be D: X=2
Last month I had 8 guppies. This month I have 20 guppies. What is the percent of increase in guppies from last month to this month?
Answer: 150% increase
Step-by-step explanation:
percent of increase: new/old × 100%-100%
--------------
new/this month: 20 puppies
old/last month: 8 puppies
new/old×100%-100%
=20/8×100%-100%
=2.5×100%-100%
=250% -100%
=150% increase

If a value of 80.4° is added to the data, how does the range change?
The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48

One angle of an isosceles triangle is known to be 68°. What would be one of the other angles?
Answer:
52 degrees
Step-by-step explanation:
Iscosceles trangle adds up to 180 degrees.
two sides are the same.
180-68= 112
112 divided by 2 = 52
the three sides are 52, 52, 68
The measure of one of the other angles would be x = 44 degree.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
Isosceles triangles have two angles that are equal.
We are given that One angle of an isosceles triangle is known to be 68°.
Since the two equal angles are 68
We have the angles 68, 68, and an unknown angle x
Now add to 180
68+68+x = 180
136+x=180
x =180-136
x =44

Micah uses the coordinate grid to draw a rectangle. Three verticles of the rectancle are (-4, 5),(-4,3) and (6,5). What are the coordinates of the fourh vertex? show micahs rectangles on the coordinate grid
Answer:
(6, 3)
Step-by-step explanation:
We already have two coordinates that make one side of the rectangle up.
(-4, 5) and (-4, 3)
Notice how only the y-coordinates change.
So, based on this logic, we should get:
(6, 5) and (6, 3)
So, the missing coordinate is (6,3)
Answer:
(6,3) is the missing 4th vertex.
Step-by-step explanation:
We know that, a rectangle is made up of 4 sides , 4 vertices and 4 edges.
According to the question, there are 3 vertices marked.
The three vertices are:
(-4,5)(-4,3)(6,5)IMPORTANT NOTEIf we are measuring the sides of a quadrilateral on a coordinate grid, we have to remember that each and every point comes twice in adjacent sides.
For example:
In the given figure, (-4) and 5 appeared twice in the three given vertices.
Now, we should remove (-4) and 5 from the three vertices.
We will be left with 6 and 3.
So, the 4th point will be the combination of 6 and 3.
Hence, we will get the 4th point as (6,3).

(This question is from graphing linear equations btw.)
Answer: C
Step-by-step explanation:
*somethingX is always the slope
*the number with no letter on the side is always the y intercept
* You can rearrange the linear equation and it stays the same. for example, y=2x+3 can become 3+2x=y, (its just that y=mx+b is more proper) but it's still the same.
* x² can NEVER be found in a linear equation.
When we talk about linear equations, we mean equations that can be written in slope intercept form, or y=mx+b.
M is the slope of the line
B is the y intercept, or the point at which tthe line crosses the y axis. For example, if the y intercept of a line were, say, 5, that means the line first crossed the y axis at the point (0,5).
That being said, I'll explain why A, B, and D are all linear equations and why C is not.
A. y=0.5x-0.2 This is in slope intercept form. It doesn't matter if the numbers are decimals, and even though you see -0.2, it still counts because technically, you can also write it as 0.5x+-0.2. + or - doesn't matter.
B. 4x+3= y. This is in slope intercept form. It looks confusing but you can just put y on the left so you have y=4x+3, which matches the slope intercept formula. Note that switching the y from left to right does not change the equation at all.
C. Is definitely wrong because you have x² . In slope intercept form, it has to be somethingx. x² and x are 2 different things, and if you see x² in any equation, it is not linear, but rather a quadratic equation. *Quadratic equations are equations written as x² +b+c=0*
D. Is in slope intercept form. It doesn't matter if you have fractions, as long as it can be written as y=mx+b (slope x+ y intercept).
I hope this helps!! :D

A new roller coaster just opened at Friday Fun Park. When Lisa got in line, a sign said the wait from that point would be 45 minutes. The actual wait was only 35 minutes. What is the percent error for the park sign's estimate?
If necessary, round your answer to the nearest tenth of a percent.
Answer: 28.6%
Step-by-step explanation:
To calculate the percent error:
1) Subtract the estimated amount by the actual amount
45-35=10
2) Divide the answer by the actual amount
10/35=0.2857
3) Multiply the answer by 100 to get the percent error
0.2857×100=28.57
Rounded that equals 28.6%
Answer: hope this helps ♡
The percent error for the park sign's estimate is 29%.
Step-by-step explanation:
45 - 35 = 10
(10 out of 35 because it's the actual amount)
10 of 35 in percentage:
(10 ÷ 35) × 100 =
0.28571..... × 100 =
28.5714.....% ≈ 29%

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Answer:
Its the third one
Step-by-step explanation:
Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

Answer:
to need interdependence in
the country
Step-by-step explanation:
The value of a is 3 and value of b is 3 if p(3,0) and q(-3,4) are on the line ax+by=6.
What is Straight Line?A line is an infinitely long object with no width, depth, or curvature.
If the points lie on the graph, they should satisfy it when substituted in place of x coordinate and y coordinate.
So, on substituting point P we get
3a=6
Divide both sides by 3
a=2
And on substituting point Q we get
-3a+4b=6
-3(2)+4b=6
-6+4b=6
Add 6 on both sides
4b=12
Divide both sides by 4
b=3
Hence, the value of a is 3 and value of b is 3.
