If arc WX = 40' and arc Y Z = 92, find m23.
Answers
Answer:
m<3 = 66°
Step-by-step explanation:
<3 is an angle with its vertex inside the circle shown in the diagram. This, it's an internal angle.
The measure of an internal angle is equal to half the sum of the measure of the arcs intercepted.
Thus, the equation that shows relationship between <3 and arc WX and arc YZ is shown below:
m<3 = ½(40 + 92)
m<3 = ½(132)
m<3 = 66°
The measure of m<3 = 66°
Calculation of the measure:Since arc WX = 40' and arc Y Z = 92
So we know that
The measure of an internal angle should be equivalent to half the sum of the measure of the arcs intercepted.
So based on this
m<3 =0.50 (40 + 92)
m<3 = 0.50(132)
m<3 = 66°
hence, The measure of m<3 = 66°

Charlie's dog?
25 pounds

11 pounds
10 pounds
Answers
Answer:
11 Pounds
Step-by-step explanation:
Since it says "about how much" we can round 18.2 to 18 and 7.4 to 7 then we subtract 18-7=11
That means the answer would be 11 pounds.

Belindas blossom boutique is having a one day sell. Any two daisies cost $1.50. How many daisies could you buy for 8.25
Answers
Answer:
11
Step-by-step explanation:
Divide 8.25 by 1.50:
8.25/1.50
= 5.5
Since any two daises cost 1.50, multiply this amount by 2:
5.5(2)
= 11
So, you could buy 11 daisies.
Plot point F so that △ABC ≅ △FGH. Identify a sequence of rigid motions that maps △ABC onto △FGH and use a theorem to complete the explanation of why the triangles are congruent.
Answers
Answer:
Step-by-step explanation:
Point F is plotted at (5, 4)
Translate ΔABC so that point B maps to point G.
B(1, -1) → G(0, 3)
Rule for the translation,
(x, y) → [x - 1, y + 4]
By this rule,
Point C will map the point,
C(-1, -2) → C'[(-1 - 1), (-2 + 4)]
→ C'(-2, 2)
A(-4, 0) → A'[(-4 - 1), (0 + 4)]
→ A'(-5, 4)
Now reflect these points across y-axis.
Rule for the reflection across y-axis,
(x, y) → (-x, y)
Points after reflection will be,
A'(-5, 4) → F(5, 4)
B'(0, 3) → G(0, 3)
C'(-2, 2) → H(2, 2)
Distance formula,
d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
AB = [tex]\sqrt{(1+4)^2+(-1-0)^2}[/tex] = [tex]\sqrt{26}[/tex]
BC = [tex]\sqrt{(-2+1)^2+(-1-1)^2}[/tex] = [tex]\sqrt{5}[/tex]
CA = [tex]\sqrt{(-4+1)^2+(-2-0)^2}[/tex] = [tex]\sqrt{13}[/tex]
FG = [tex]\sqrt{(5-0)^2+(4-3)^2} =\sqrt{26}[/tex]
GH = [tex]\sqrt{(2-0)^2+(2-3)^2}=\sqrt{5}[/tex]
HF = [tex]\sqrt{(4-2)^2+(5-2)^2}=\sqrt{13}[/tex]
AB ≅ FG, BC ≅ GH, CA ≅ HF
By the SSS property Triangle congruence theorem, ΔABC ≅ ΔFGH

1. A daycare center charges a $100 sign up fee, plus $50 per week. Write an equation that represents the total cost, f(x), for x weeks.
f(x) = _____x + ______
a. Identify the rate of change and interpret its meaning in the context of the problem.
b. Identify the y-intercept and interpret its meaning in the context of the problem.
c. What does x represent? What does f(x) represent?
d. Find the cost for a baby to attend daycare for 12 weeks. Write your answer using function notation.
e. Calculate f(-3). Explain what this question is asking you to find in the context of the problem, then discuss the reasonanbleness of this question and its answer.
Answers
Answer:
f(x)=50x+100
a)rate of change is 50
b)y-intercept is 100
c)x represents the no. of weeks
f(x) represents the the total cost for x weeks.
d)f(12)=700
e)Cost and week cannot be negative
Step-by-step explanation:
Sign up fee at daycare = $100
Cost of 1 week = 50
Cost of x weeks = 50 x
So, Total cost = 100+50x
Thus f(x)=50x+100
a)
General equation : y=mx+c
m = slope = rate of change
On comparison
m = 50
So, rate of change is 50
50 is the cost of daycare per week
b)
y intercept : y intercept is a point where a line 's graph intersects (crosses) the Y-axis i.e. x=0
Substitute x = 0 in equation
f(x)=50(0)+100
f(0)=100
So, y-intercept is 100
$100 is a signup fee
c)
x represents the no. of weeks
f(x) represents the the total cost for x weeks.
d)
Substitute x = 12
So, Cost for a baby to attend daycare for 12 weeks:
f(12)=50(12)+100
f(12)=700
e)
f(-3)=50(-3)+100=-50
Here it is asking about negative 3 weeks which is not possible
Since no. of weeks cannot be negative
On solving we are getting the negative total cost
Cost and week cannot be negative

I want to decorate my room with leaves and turkeys for Thanksgiving. The number of leaves is twenty more than twice the number of turkeys. The number of leaves is ten less than 4 times the number of turkeys. How many of each type of decoration should I use?
Answers
Answer:
50 leaves, 15 turkeys
Step-by-step explanation:
set up an equation
l = leaves
t = turkeys
l = 2t+20
l = 4t-10
2t+20=4t-10
30=2t
15=t (so that means that there would be 15 turkey decorations, but we're not done yet)
substitute (either equation):
l = 2(15)+20
l = 30+20
l = 50 (so this means there would be 50 leaves)

Consider matrix A.
A=[−385−123]
What matrix results from the elementary row operations represented by −3R2+4R1?
Enter your answer by filling in the boxes.
Answers
Answer:
[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]
Step-by-step explanation:
Given the matrix A
[tex]\left[\begin{array}{ccc}-3&8&5\\-1&2&3\end{array}\right][/tex]
We are to find the matrix that results from the elementary row operations represented by −3R2+4R1
R2 means row 2
R1 means row 1
Applying the elementary row operation will change the second row of the matrices.
For the first column, second row (a₂₁)
If R1 = -3, R2 = -1
a₂₁ = -3R2+4R1
a₂₁ = -3(-1)+4(-3)
a₂₁ = 3-12
a₂₁ = -9
For a₂₂
If R1 = 8, R2 = 2
a₂₂ = -3R2+4R1
a₂₂ = -3(2)+4(8)
a₂₂ = -6+32
a₂₂ = 26
For a₂₃
If R1 = 5, R2 = 3
a₂₃ = -3R2+4R1
a₂₃ = -3(3)+4(5)
a₂₃ = -9+20
a₂₃ = 11
Hence the resulting matrix will be:
[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]-3R2+4R1
Answer:
[-3 5 2]
[-36 23 -1]
Step-by-step explanation:
Note abidemiokin did the steps right just has the "given" wrong.
Given the matrix A
[-3 5 2]
[ 8 -1 3]
We are to find the matrix that results from the elementary row operations represented by −3R2+4R1
R2 means row 2
R1 means row 1
Applying the elementary row operation will change the second row of the matrices.
For the first column, second row (a₂₁)
If R1 = -3, R2 = 8
a₂₁ = -3R2+4R1
a₂₁ = -3(8)+4(-3)
a₂₁ = -24-12
a₂₁ = -36
For a₂₂
If R1 = 5, R2 = -1
a₂₂ = -3R2+4R1
a₂₂ = -3(-1)+4(5)
a₂₂ = 3+20
a₂₂ = 23
For a₂₃
If R1 = 2, R2 = 3
a₂₃ = -3R2+4R1
a₂₃ = -3(3)+4(2)
a₂₃ = -9+8
a₂₃ = -1
Hence the resulting matrix will be:
[-3 5 2]
[-36 23 -1] -3R2+4R1

Prob (Skip test drive) = P (STD) 11% = 0.11
Prob (Online search & Skip test drive) = P (OS ⋂ STD) = 7% = 0.07
Prob (Online search or Skip test drive) = P (OS U STD) :-
