It is congruent doe to the angle side angle congruence thereom AKA ASA
Step-by-step explanation:
That means there are two angles and one side in between. A pair of triangles that follow this rule has an angle that is congruent to one angle. Then a side that has a tick mark after the angle must match another. Then the last angle has to match another angle ( and it can't be the same angle as before). Usually the first pair angles have 1 semicircle and the second pair has 2 semicircles.

20 minutes
Step-by-step explanation:
hope it helps u
plzz plzz plzz mark as brainliest
Answer: 3 hours
Step-by-step explanation:
To solve this problem, utilize something called the unit rate.
Because it takes three workers(x) 8 hours to apply two coats of paint, simply write: x/3 = 8 ÷ 2.
x/3 = 4
x = 4 * 3
x = 12
Thus, it takes one worker 12 hours, or 720 minutes to apply one coat of paint. Thus, because the number of workers is multiplied by 4, divide the time spent by 4, to get 3 hours, or 180 minutes.
Hope it helps :) and let me know if you want me to elaborate.
N.B. This is an inverse relationship, as when the number of workers increases, the amount of time decreases.

Number of pennies =
Number of nickels =
Number of quarters =
Answers
Answer:
There are 20 pennies, 33 nickels and 11 quarts.
Step-by-step explanation:
Total number of coins = 64 Amount of money = $4.60 = 460 cents
x = pennies y = nickels x = quarters
y x 3 = x
x + y + z = 64 coins
x + 5y + 25z
x + 4z = 64
x + 40z = 460
x = 20 z = 11
y = 3z = 33

The local pool near Paxton's house charges a one-time registration fee of $18.25 and $17.50 per month. Last year, Paxton paid $105.75. How many months was Paxton a member of the pool?
Answers
Solving a linear equation we can see that Paxton was a member for 5 months.
How many months was Paxton a member of the pool?We know that the local pool near Paxton's house charges a one-time registration fee of $18.25 and $17.50 per month, then the cost for x months is modeled by the linear function.
f(x)= 18.25 + x*17.50
We know that Paxton paid $105.75, then we need to solve the equation:
105.75 = 18.25 + x*17.50
Solving that for x we will get:
105.75 - 18.25 = x*17.50
87.50/17.50 = x
5 = x
Paxton was a memeber for 5 months.

Answers
Answer:
y = 3x + 7.
Step-by-step explanation:
The slope = 6/2 = 3
y-intercept = 7.
Answer:
y = 3x + 7
Step-by-step explanation:
y-intercept = 7 {where the line intersect at y-axis (0,7)}
Plot a point: (-1 ,4 )
Slope intercept form: y = mx + b
y = mx + 7
4 = m*(-1) + 7
4 = -m + 7
4 - 7 = -m
-m = -3
m = 3
y = 3x + 7

Answer:
20.63%
Step-by-step explanation:
% change = (New Value - Initial Value)/(Initial Value) * 100
= (150-189)/189 * 100
= -20.63%
Though the value comes as negative but it only indicates that it is a percentage decrease. As the question mentioned that the value is decreased, the final answer would be only 20.63%.

3. A floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor. Find the area of the floor that is not carpeted.
Answers
Answer:
Length of floor = 5 m and breadth of floor = 4 m
Area of floor = length x breadth
= 5 m x 4 m = 20 m.sq
Now, Side of square carpet = 3 m
Area of square carpet = side x side = 3 x 3 = 9 m.sq
Area of floor that is not carpeted = 20 m – 9 m = 11 m.sq
Answer:
[tex]11 {m}^{2} [/tex]Step-by-step explanation:
First Condition:Given ,
Length of a floor = 5 m
Width of the floor = 4 m
Therefore,
Area of the floor
= l × b
= 5m × 4m
[tex] = 20 {m}^{2} [/tex]
Second Condition:Given,
Sides of a square carpet = 3 m
Therefore,
Area of the carpet
= s × s
= 3m × 3m
[tex] = {9m}^{2} [/tex]
At last:Now,
Area of the floor that is not carpeted is
= Area of the floor - Area of the carpet
[tex] = {20m}^{2} - {9m}^{2} [/tex]
[tex] = 11 {m}^{2} (ans)[/tex]

Caroline leaves her apartment and walks 45° north of west for 1000 feet and then walks 200 feet due north to go to the grocery store. How far and at what north of west
quadrant is Caroline from being at her apartment?
Answers
Answer:
1150 ft W 52° N
Step-by-step explanation:
There are several ways a problem like this can be solved. Perhaps the easiest is to make use of a suitable vector calculator.
Using West as the reference for angles measured clockwise (toward north), the final position is ...
1000∠45° +200∠90° = 1150.149∠52.063°
__
You can also figure this using the Law of Cosines. It will tell you the resultant distance (c) in terms of the individual distances (a, b) and the angle between them (135°).
c² = a² +b² -2ab·cos(C)
c² = 1000² +200² -2·1000·200·cos(135°) ≈ 1,322,842.7
c ≈ √1322842.7 ≈ 1150.149
The angle difference from 45°N can be found using the Law of Sines.
sin(B)/b = sin(C)/c
B = arcsin(b/c·sin(C)) = arcsin(200/1140.149·sin(135°)) ≈ 7.063°
This means Caroline's bearing from home is 45° +7.063° ≈ 52° north of west.
Caroline's final position is 1150 W 52° N in relation to her home.

What is an equation of the line that passes through the points (-6, -4)
and (-4, 0)?
Answers
Answer:
y=2x+8
Step-by-step explanation:
Hi there!
We want to find the equation of the line that passes through the points (-6, -4) and (-4, 0).
There are 3 ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y interceptPoint-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a pointStandard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be equal to zero, and a cannot be negativeLet's write the equation in slope-intercept form, which is the most common way to do it.
We'll need to start by finding the slope of the line
The formula for the slope calculated from two points is [tex]\frac{y_2- y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Even though we are already given two points, let's label their values in order to avoid any confusion and mistakes for later:
[tex]x_1=-6\\y_1=-4\\x_2=-4\\y_2=0[/tex]
Substitute these equations into the formula to find the slope (m):
m=[tex]\frac{y_2- y_1}{x_2-x_1}[/tex]
Substitute (remember: we have NEGATIVE numbers and SUBTRACTION, so we'll end up subtracting a negative):
m=[tex]\frac{0- -4}{-4--6}[/tex]
Simplify
m=[tex]\frac{0+4}{-4+6}[/tex]
Add the numbers together
m=[tex]\frac{4}{2}[/tex]
Divide
m=2
The slope of the line is 2
We can immediately plug it into the formula for slope-intercept form as m:
y=2x+b
Now we need to find b
As the equation passes through both (-6, -4) and (-4, 0), we can use either one of them to solve for b
Taking (-4, 0) for example:
Substitute -4 as x and 0 as y:
0=2(-4)+b
Multiply
0=-8+b
Add 8 to both sides
8=b
Substitute 8 as b into the equation
y=2x+8
Hope this helps!

Answers
Answer:
slope: 5intercept: 4Step-by-step explanation:
It works well to find the slope using points where the graph crosses grid intersections. We see two of those are (0, 4) and (1, 9). The slope formula tells us ...
m = (y2 -y1)/(x2 -x1)
m = (9 -4)/(1 -0) = 5
The slope is 5.

The y-intercept is the value of y when x=0. The point (0, 4) tells us ...
The y-intercept is 4.
