Find the missing side length, N.
We know these triangles are congruent with the missing side, N would be equal to 15.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
We know these triangles are congruent.
To find the missing side, N
ΔABC ≅ΔQRS
AC/QS = BC/RS
2/5 = 6/n
n = 6 x 5/2
n = 30/2
n = 15
Thus, the value of N is 15.

A 5.5-foot-tall woman walks at 8 ft/s toward a street light that is 22 ft above the ground. What is the rate of change of the length of her shadow when she is 20 ft from the street light? At what rate is the tip of her shadow moving?
Answer: [tex]\frac{8}{3}\ ft/s[/tex]
Step-by-step explanation:
Given
length of shadow =22 ft
height of woman =5.5 ft
speed of woman [tex]\frac{dy}{dt}=8\ ft/s[/tex]
from the figure, we can write
[tex]\frac{22}{x+y}=\frac{5.5}{x}[/tex]
at given instant
y=20 ft
so, using similar triangle properties
[tex]\frac{22}{x+20}=\frac{5.5}{x}\\22x=5.5x+110\\16.5x=110\\x=6.67\ ft[/tex]
Again we can write
[tex]\dfrac{22}{x+y}=\dfrac{5.5}{x}\\22x=5.5x+5.5y\\16.5x=5.5y\\3x=y\\\text{differentiate w.r.t time} \\3\frac{dx}{dt}=\frac{dy}{dt}\\\frac{dx}{dt}=\frac{1}{3}\times 8=\frac{8}{3}\ ft/s\ \text{away from the woman}[/tex]
The measure of each interior angle of a regular polygon is 120°. Find the number of sides.
Answer:
6
Step-by-step explanation:
You can memorize these for the smaller shapes
for equilateral polygons:
triangle: 60
square: 90
pentagon: 108
hexagon: 120
Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.
So the measure of each angle on average would be (s-2)*180/s.
There (s-2)*180/s = 120
180(s-2) = 120s
180s-360 = 120s
60s = 360
s = 6
Hannah deposited the same amount of money into her savings account each month after 5 months she had $2,550 into the savings account after 8 months she had $3,300 and the savings account create an equation that models the amount a and the savings account after x months not included interest show your work ever explain how you determine your equation
Answer:
a = 250x + 1300Step-by-step explanation:
We have pairs (5, 2550) and (8, 3300)
Find the rate of change:
(3300 - 2550)/(8 - 5) = 750/3 =250$250 is the amount added to savings account every month
Initial amount was:
2550 - 5*250 = 2550 - 1250 =1300Since the change is linear and we have y-intercept and slope, we can show the amount after x months as:
a = 250x + 1300PLS HELP ASAP I DONT HAVE TIME. IT ALSO DETECTS IF ITS RIGHT OR WRONG. SHOW PROOF.

Select the graph for the solution of the open sentence lxl +3>3
No solution
Closed circle on 0 going to the right
Open circle going out left and right
Open circle only going to the right
Answer:
[tex]x>0\:or\:x<0[/tex]
As seen in graph, there is an open circle on 0, and it goes out left and right.
Option C is correct option.
Step-by-step explanation:
We need to draw the graph for the solution of the open sentence [tex]|x| +3>3[/tex]
First we will solve the inequality: [tex]|x| +3>3[/tex]
Adding -3 on both sides
[tex]|x| +3-3>3-3\\|x| >0[/tex]
We know that [tex]If\:|x|>0,\:then\:x>0\:or\:x<0[/tex]
So, we have
[tex]x>0\:or\:x<0[/tex]
Now, the graph is attached in the figure below
As seen in graph, there is an open circle on 0, and it goes out left and right.
Option C is correct option.

Answer: 6:5
Step-by-step explanation:
Let each little rectangle have the dimensions a by b (where a is the length and longer than b, the width). We find that l=3a because there are 3 lengths of a along l at the top of the crate and that l=4b because there are 4 lengths of b along l at the bottom of the crate. In addition, w=2b+a because there are 2 lengths of b and one length of a along w. Therefore, we can find b and a in terms of l and plug them into w=2b+a to find w in terms of l:
l=4b
b=l/4
l=3a
a=l/3
w=2b+a
w=2(l/4)+(l/3)
w=l/2+l/3
w=5l/6
If w=5l/6, l:w=l/(5l/6)=l(6/5l)=6/5
The correct answer is 6:5.
у = -3х + 4
у = 3х - 2
Answer:
y =2
then u should put 2 in y = 3x -2 or y = -3x + 4
= y =3x - 2
= 2 = 3x - 2
= 2 + 2 = 3x
= 4 = 3x
=x = 4/3
Maria Louisa looks at a sequence of shapes and records the number of vertices in each of the shapes in the sequence. The first shape has 7 vertices, the second shape has 13 vertices, and the third shape has 19 vertices. If Maria Louisa assumes that the number of vertices in the sequence of shapes follows the same pattern, how many vertices would she expect the 17 shape to have?
Answer:
103
Step-by-step explanation:
appears to be an arithmetic sequence question where sequence is 7, 13, 19 meaning the initial value is 7 and the common difference is 6 so we'll plug into this formula:
[tex]a_{17}[/tex] = 7 + (17 - 1) · 6
= 7 + (16 · 6)
= 7 + 96
'7' because that's the initial value
'6' because that the common difference
'17' because that's the position the question is asking

Solve for x.
3x-6
130
8x+4
Answer: x = 12
Step-by-step explanation:
(180 - 130) + (3x - 6) + (8x + 4) = 180
180 - 130 + 3x - 6 + 8x + 4 = 180
48 + 11x = 180
48 + 11x - 48 = 180 - 48
11x = 132
11x ÷ 11 = 132 ÷ 11
x = 12
The required value of variable "x" is 12 which is determined by the property of interior angles.
What is a Triangle?Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol Δ.
We know that the linear pair of angles are adjacent angles the sum of their measures is 180°
Since the sum of all interior angles of the triangle = 180°
(180 - 130) + (3x - 6) + (8x + 4) = 180
180 - 130 + 3x - 6 + 8x + 4 = 180
Rearrange the terms of variable "x" and combine them,
48 + 11x = 180
48 + 11x - 48 = 180 - 48
11x = 132
x = 132/11
x = 12
Therefore, the required value of variable "x" is 12.
