Find the value of x and y. Write your answer in simplest radical form.
Answer:
Y=10
x=14.14
Step-by-step explanation:
Because the two smaller angles are equal, it is an isosceles triangle with both legs equal in length.
so y=10
By the Pythagorean theorem, x^2=10^2+10^2
x^2=200
x=14.14
HELP PLEASEEEE AND THANK YOU SORRY CAPS LOCK
Answer:
B, 1/5
Step-by-step explanation:
Because 2/5 + 2/5 = 4/5 so 5/5 - 4/5 = 1/5 so the answer would be 1/5
Write an equation to fond the nth term of each sequence. Then find a9. 5,20,80
Answer: a₉ = 327,680
Step-by-step explanation:
This seems to be a geometric sequence.
The recursive relation for this type of sequence is:
aₙ = aₙ₋₁*r
Where r is a constant.
Then we also have:
aₙ/aₙ₋₁ = r.
then we can find the value of r if we take the quotient of different consecutive terms, for example, the quotient of the second and firs term is:
r = 20/5 = 4
And the quotient between the third and second term is:
r = 80/20 = 4
Then we can conclude that r = 4.
And also, the n-th term of this sequence can be written as:
aₙ = a₁*r^(n - 1)
such that:
a₁ = 5
r = 4
Then the n-th term of this sequence is:
aₙ = 5*(4)^(n - 1)
Then the term a₉ can be found if we just replace n by 9 in the above equation:
a₉ = 5*(4)^(9 - 1) = 5*(4)^(8) = 327,580

Jared and Morgan are making two gazebos in the shape of regular polygons, Jared's gazebo is a heptagon
and has an apothem of 13.6 feet and an area of 623.5 ft and Morgan's gazebo is an octagon has an
apothem of 12.5 feet and an area of 517.8 ft". Which gazebo has the longest side length?
The gazebo with the longest side length is the heptagon.
What is the side length of the heptagon?
A heptagon is a polygon with 7 sides. It has 7 edges and vertices.
The length of the side of a heptagon = (area of the heptagon x 2) / (number of sides x length of the apothem)
= (623.5 x 2) / (7 x 13.6)
= 1247 / 95.2
= 13.1 feet
What is the side length of the octagon?
A octagon is a polygon with 8 sides. It has 8 edges and vertices. The sum of internal angles in 135 degrees.
The length of the side of a octagon = (area of the octagon x 2) / (number of sides x length of the apothem)
= (517.8 x 2) / (12.5 x 8)
= 1035.6 / 100
= 10.356 feet

Answer:
26x2,
52xπ
Step-by-step explanation:
The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.
What is the circumference of a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let 'r' be the radius of the circle. The circumference of the circle will be
C = 2πr units
The radius of the semicircle is given as,
r = 26 cm
Then the circumference of the semicircle is half of the circle. Then we have
C = 1/2 x 2πr
C = πr
At r = 26 cm, then we have
C = 3.14 x 26
C = 81.64 cm
The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

Mickey said that 45.7654 rounded to the nearest thousandth is 45.765 and Nicole said that it was 45.766. Who is correct and why?
Answer:
Mickey
Step-by-step explanation:
Mickey is correct because if you look at the number 45.7654 whenever you round to the nearest thousandth it'll be 45.765
5 is the thousandth place so look to the right. If the number to the right is greater than 5 it'll round to 47.766 but since it's a four ti rounds down.

Answer: The winning order is:
Spike
Boris
Percival.
Step-by-step explanation:
We can write the number of steps that each one did as linear relationships of the form:
y = a*x + b
where:
a represents the slope, in this case, is the velocity of each kid.
x represents the time
b represents the steep at which each one starts.
We know that the race is completed with 99 steps.
Now, we know that in one unit of time (we do not know how long this is, and this does not matter).
Boris can run 5 steps in one unit of time
Spike can run 4 steps in one unit of time
Percival can run 3 steps in one unit of time.
Now let's write the equations for each one.
B(x) will be Boris's equation, we know that he starts from the bottom, then his equation is:
B(x) = 5*x + 0
B(x) = 5*x
Now we can find the number x needed to reach the 99 step, this is:
B(x) = 99 = 5*x
99/5 = x = 19.8
Boris needs 19.8 units of time to finish the race.
S(x) will be the equation for Spike, we know that he starts 21 steps up, then his equation is:
S(x) = 4*x + 21
Let's find the value of x such that S(x) = 99
S(x) = 99 = 4*x + 21
99 - 21 = 4*x
78 = 4*x
78/4 = x = 19.5
So Spike needs 19.5 units of time to finish the race, so he needs less time than Boris, this means that he finishes before Boris.
P(x) is the equation for Percival, we know that he starts 38 steps up, then his equation is:
P(x) = 3*x + 38
Again, we want to find the value of x such that P(x) = 99
P(x) = 99 = 3*x + 39
99 - 38 = 3*x
61 = 3*x
61/3 = x = 20.33
So Percival needs 20.33 units of time to finish the race, he is the one that needs more time, so he will be the last one to finish.
The winning order is:
Spike
Boris
Percival.

Answer:

Step-by-step explanation:
you want to create two equations for each situation so if v=number of students that can fit in a van and c=number of students that can fit in a car then you can create the equations 3v+1c=22 and 2v+4c=28
then you want to make both equations equal to c
so for the first one you subtract both sides by 3v and you get c= -3v+22
and for the second one you subtract 2v from both sides and end up with 4c=-2v+28 and then divide both sides by 4 leaving you with c= -1/2v+7
then you make both of those equations equal to each other and solve for v
so -3v+22= -1/2v+7 and you end up with v=6
therefore, each van can hold 6 students
Solve the equation 4(c-3)=8 What are two ways to start solving this equation? Choose BOTH ways Subtract 4 from both sides to get c-3=4 Use the distributive property to get 4c-12=8 Divide both sides by 4 to get c-3=2 Use the distributive property to get 4c-3=8 Add 3 to both sides to get 4c=11
Answer:
b) Use the distributive property to get 4c-12=8
c) Divide both sides by 4 to get c-3=2
Step-by-step explanation:
Solve the equation 4(c-3)=8
What are two ways to start solving this equation?
We are given the Equation
4(c - 3) = 8
The two ways to start solving this Equation is given as:
1. 4(c - 3) = 8
We expand the brackets, using Distributive property
4c - 12 = 8
Or
2. 4(c - 3) = 8
Divide both sides by 4
4(c - 3)/4 = 8/4
c - 3 = 2
Therefore, options b and c is correct

Taylor has dd dimes and qq quarters. She has a maximum of $4 worth of coins altogether. Write this situation as an inequality.
Answer: .10d+.25q<_ 4
Step-by-step explanation:
d= dimes and q = quarters
dimes are worth .10 and quarters are worth .25
The inequality for the given situation is
0.1d + 0.251 ≤ 4
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
10 dimes = 1 dollar
1 dime = 0.1 dollar
4 quarters = 1 dollar
1 quarter = 0.25 dollar
Now,
The maximum amount is $4.
So,
0.1d + 0.251 ≤ 4
Thus,
The inequality is 0.1d + 0.251 ≤ 4.

what is the standard form of the quadratic function that has a vertex of (4,-2)and goes through the point ( 5,0)
A. y = 2x^2 - 16x + 30
B. y = 2x^2 - 16x + 32
C. y= 2 (x - 4)^2 - 2
D. y = 2x^2 - 8x - 2
Answer:
C: y = 2(x - 4) - 2
Step-by-step explanation:
The vertex formula of a quadratic is y - k = m(x - h).
Here the vertex is at (4, -2), and so we now have y + 2 = a(x - 4).
Find a: letting y = 0 and x = 5, we get 0 + 2 = a(5 - 4), which means a = 2.
The desired equation is C: y = 2(x - 4) - 2
