Please help! 20 pts and brainliest!! An isosceles triangle has an angle that measures 124°. Which other angles could be in that isosceles triangle? Choose all that apply. 124, 28, 65, 41
Answer:
Step-by-step explanation:
In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:
124+2x=180
2x=56x=28

What is the perimeter of this triangle?
(-4,5)
(8,5)
(8,-4)
A. 36 units
В.
39 units
33 units
D
42 units
Answer:
Perimeter of triangle = 12 + 9 + 15
= 36 units
Therefore, option A is correct.
Step-by-step explanation:
The given points
(-4, 5)(8, 5)(8, -4)From the table, it is clear the side containing the line segment joining the points (-4, 5) and (8, 5) is a straight horizontal line.
Thus, the length of the horizontal distance from the points (-4, 5) and (8, 5) will be:
8-(-4) = 12 units
From the table, it is clear the side containing the line segment joining the points (8, 5) and (8, -4) is a straight vertical line.
Thus, the length of the vertical distance from the points (8, -4) and (8, 5) will be:
5-(-4) = 9
Now, finding the length of the side containing the segment (8, -4) and (-4, 5) using the formula:
[tex]\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(5-\left(-4\right)\right)^2}[/tex]
[tex]=\sqrt{\left(-4-8\right)^2+\left(5+4\right)^2}[/tex]
[tex]=\sqrt{12^2+9^2}[/tex]
[tex]=\sqrt{144+81}[/tex]
[tex]=\sqrt{225}[/tex]
[tex]=\sqrt{15^2}[/tex]
[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]
[tex]=15[/tex]
We know that the Perimeter of a rectangle is the length of all the sides of the triangle. Therefore, combining all the lengths of the line segments
Thus,
Perimeter of triangle = 12 + 9 + 15
= 36 units
Therefore, option A is correct.
25x^3+5x^2+30x+6=0 solve
Answer:
x = -1/5, x = i sqrt(30)/5, x = -i sqrt(30)/5
Step-by-step explanation:
25x^3 + 5x^2 + 30x + 6 = 0
5x^2(5x + 1) + 6(5x + 1) = 0
(5x + 1)(5x^2 + 6) = 0
5x + 1 = 0
5x = -1
x = -1/5
5x^2 + 6 = 0
5x^2 = -6
x^2 = -6/5
x = +/- sqrt(-6/5)
x = +/- i * sqrt(30)/5
x = i sqrt(30)/5 or x = -i sqrt(30)/5
The smallest bone in the human body is the stapes (or stirrup) in the inner ear, at about 3 mm. The largest bone is the femur, which is about 480 mm in length in an average male. About how many times smaller is the stapes than the femur in the human body?
Answer:
160
Step-by-step explanation:
It's simple you have to do 480 divided by 3 and you will get 160. To check if you multiply 3x160 it would equal 480. So 160 times larger. Hope this helps!

Step-by-step explanation:
Owen and his children went into a restaurant where they sell hotdogs for $4 each and tacos for $2.50 each. Owen has $60 to spend and
buy a minimum of 18 hotdogs and tacos altogether. If x represents the number of hotdogs purchased and y represents the number of tac
purchased,
Answer:
Hotdogs is 10
and Tacos 8 in numbers purchased
Step-by-step explanation:
Step one:
given data
Le x represents the number of hotdogs purchased
and y represents the number of tac
hotdogs = $4 each
and tacos = $2.50 each
The total amount at hand = $60
Step two:
The systems of the equations for the situation is given as
4x+2.5y= 60---------1
x+y=18-----------------2
Required
The number of Hotdogs and Tacos purchased
from 2
x= 18-y
put x= 18-y in eqn 1
4(18-y)+2.5y= 60
72-4y +2.5y=60
collect like terms
-4y+2.5y=60-72
-1.5y= -12
divide both sides by -1.5
y= -12/-1.5
y= 8
put y= 8 in eqn 2
x+8=18
x= 18-8
x= 10

Aiden plant grew 75 inches in 100 weeks. At this rate, how much would it grow in 30 weeks
Answer:
22.5 inches
Step-by-step explanation:
To find the unit rate, you divide the amount the plant grew by the amount of weeks. We learned that the plant grew 75 inches in 100 weeks, so we divide 75/100, to get 0.75. This means that the plant grows 0.75 inches per week, so in 30 weeks, it would grow 22.5 inches. This is calculated by multiplying 0.75 by 30 weeks.

On what interval(s) of x is f(x) increasing?
On what interval(s) of x is f(x) decreasing?
Answer:
Increasing → (-∞, -0.5)
Decreasing → (-0.5, ∞)
Step-by-step explanation:
From the picture attached,
Vertex of the parabola represents the highest point of the curve of a quadratic function 'f'.
Left part from the vertex is increasing and the right side is increasing.
x-coordinates of the vertex,
x = -0.5
Therefore, graph of the function is increasing in the interval (-∞, -0.5)
And decreasing in the interval (-0.5, ∞).

ABC has A(-3,6),B(2,1),and C(9,5) as its vertices the length of side AB is units . The length of side BC is ?units . The length of side AC is ? Units .ABC ?
Answer:
The length of side AB is [tex]\sqrt{50}[/tex] units.
The length of side BC is [tex]\sqrt{65}[/tex] units.
The length of side AC is [tex]\sqrt{145}[/tex] units.
Step-by-step explanation:
To find the length of each side, we use the formula for the distance between two points.
Distance between two points:
Points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Side AB:
Points [tex]A(-3,6),B(2,1)[/tex]. So the distance between them is:
[tex]D = \sqrt{(2-(-3))^2 + (1-6)^2} = \sqrt{50}[/tex]
The length of side AB is [tex]\sqrt{50}[/tex] units.
Side BC:
Points [tex]C(9,5),B(2,1)[/tex]. So the distance between them is:
[tex]D = \sqrt{(2-9)^2 + (1-5)^2} = \sqrt{65}[/tex]
The length of side BC is [tex]\sqrt{65}[/tex] units.
Side AC:
Points [tex]A(-3,6),C(9,5)[/tex]. So the distance between them is:
[tex]D = \sqrt{(9-(-3))^2 + (5-6)^2} = \sqrt{145}[/tex]
The length of side AC is [tex]\sqrt{145}[/tex] units.

Write a equation in slope intercept form
Answer:
[tex]y=\frac{1}{2} x-8[/tex]
Step-by-step explanation:
Slope-intercept form is organized in the form y=mx+b, where m is the slope and b is the y-intercept.
Because we're already given the values, we just have to plug them into the equation.
[tex]y=mx+b\\y=\frac{1}{2} x+(-8)\\y=\frac{1}{2} x-8[/tex]
To graph this equation, first plot a point at (0, -8). This is because the y-intercept is -8, meaning that the line crosses the y-axis when y=-8.
Then, plot the next point using the slope. The slope is equal to the rise/run of the line, or the number of units the line travels upwards / the number of units the line travels to the right. Because the slope is 1/2, we know that for every 2 units a point travels to the right, it goes up by 1 unit.
