isosceles triangle, please find y and x and give/show work.
Step-by-step explanation:
because it is an isoceles triangle (both legs are equally long), also both side angles on the baseline must be equally large.
so, we have
4x + 3 = 2x + 29
4x = 2x + 26
2x = 26
x = 26/2 = 13
41 = 3y + 2
39 = 3y
y = 39/3 = 13
Find three consecutive odd numbers whose sum is 1899.
Answer:
631, 633, 635
Step-by-step explanation:
Odd numbers exists in AP with common difference of 2.
That is; 1, 2, 5, 7 etc
So lets say the middle number of the three consecutive numbers is x, the next number to it Will be (x+2), and the previous number will be (x-2)
Therefore, the sequence is (x-2), x, (x+2) ... (1)
and the series will be, (x+
-2) + x + (x+2) = 1899
Solve for x;
x + x + x - 2 + 2 = 1899
3x + 0 = 1899
x = 1899 ÷ 3
x = 633
Therefore the consecutive odd numbers (following 1) is: (633 - 2), 633, (633+2) = 631, 633, 635

Solving the proportion 22 miles/ 55 hours :: 12 miles/ k hours using cross products, value of h is 30.
Define proportion.Comparing two integers that each stand for a component of a whole results in a proportion. In essence, a percentage declares that two fractions are equal, regardless of the difference in amount. For instance, the ratio of half of 10 marbles to half of 50 marbles is 10. When determining if two ratios or fractions are equivalent, the proportion formula is utilized. By dividing the supplied values, we may determine the missing value. One way to express the percentage formula is as a: Whereas a and d are the extreme terms and b and c are the mean terms, b::c: d = a/b = c/d.
Given,
22 miles/ 55 hours = 12 miles/ k hours
Solving the proportion using cross products,
22 × h = 12 × 55
22 × h = 660
h = 660 ÷ 22

ABCD is none of these.
The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal, so option A is correct.
What is parallelogram?A unique kind of quadrilateral created by parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but for it to be a parallelogram, its opposite sides must be parallel.
Given data:
The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3),
Calculate the distance of sides as shown below
[tex]AB = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
AB = [tex]\sqrt{[-7-(-8)]^2 + (8-5)^2}[/tex]
AB = √(1² + 3²)
AB = √10
Calculate
BC = [tex]\sqrt{[-1-(-7)]^2+(6 - 8)^2}[/tex]

What is the maximum sales level?
By using the concept of maxima of a function, it can be calculated that-
He must spent $8000 to maximize sales
Maximum sales is 1548000 units
What is maxima of a function?
Maxima of a function gives the maximum value of the function within a given domain or within an interval.
Here,
S(x) = [tex]-2x^3 + 12x^2 + 192x + 268[/tex]
S'(x) = [tex]-6x^2+24x+192[/tex]
S'(x) = 0
[tex]-6x^2+24x+192=0\\-6(x^2-4x-32)=0\\x^2-4x-32=0\\x^2-8x+4x-32=0\\x(x-8)+4(x-8)=0\\(x-8)(x+4) = 0\\[/tex]
x - 8 = 0 or x + 4 = 0
x = 8 or x = -4
But x = -4 is not possible
So he must spent $8000 to maximize sales
S''(x) = -12x + 24
S''(8) = -12(8) + 24 = -72<0
Hence sales is maximum
Maximum sales = S(8) = [tex]-2(8)^3+12(8)^2+192(8)+268[/tex]
= 1548
Maximum sales is 1548000 units

A rectangular garden is 20 meters wide.the perimeter of the garden is 110 meters. What is the length
Answer: the length of the garden is 35 meters
Step-by-step explanation:
The formula for perimeter is 2W+2L=perimeter
With the given information you can plug in the values and use them to solve for the length, L.
W=20 and p=110 so now plug them in and solve for L
2(20)+2L=110 multiply the 20 by 2
40+2L=110 subtract 40 from both sides
2L=70 divide both sides by 2
L= 35 meters
You can check to see if you got the right answer by plugging the L in and find p.
2(20)+2(35)=40+70=110 by getting 110 it means it is the correct value for L

parabola?
Answer:
The y-intercept of the table shown is (0, 1).
How to find a y-intercept of a parabola/equation?The y-intercept of the parabola can be found by verifying if any coordinates from the table has x = 0 and y = some specific value. If there is a coordinate point such that the value of both is x = 0 and y = any value, then the value of y is the y-intercept of the parabola. Further explained in example:
Example: if a line passes through a coordinate point (0, 4), the y-intercept for that line is four because the value of x is 0 and y is 4.
Solving the Problem/Question (Applying the method stated above):
From the table, we can tell that the parabola passes through the following coordinate points: (-2, -11); (-1, -4); (0, 1); (1, 4); (2, 5); (3, 4); (4, 1).
From all the coordinates, we find that (0, 1) has the value of x as 0 and the value of y as 1. Therefore, this coordinate point (0, 1) is the y-intercept.

Answer:
The probabilities are:
1. 1/6
2. 1/2
3. 9/14
4. 0
5. 1
So ordering from least to most probable:
4. 7 on a 6 sided die
1. 4 on a 6 sided die
2. heads with a coin
3. red or green marble
5. <7 on a 6 sided die.
Step-by-step explanation:
1. The probability of rolling 4 on a 6-sided die is 1/6, as each side is equally probable.
2. The probability of flipping a coin onto heads is 1/2, as there are 2 equally probable outcomes.
3. The probability of drawing red or green out of 6 red, 5 blue, 3 green is 9/14 (9 positive outcomes out of 14).
4. The probability of rolling a 7 with a 6 sided die is 0, as there is no such number on the die.
5. The probability of rolling a number less than 7 on a 6 sided die is 100%, or 1, because any outcome is positive (we can only roll numbers smaller than 7).
The probabilities are:
1. 1/6
2. 1/2
