If ABC is similar to DEF, the sides of ABC must be congruent to the corresponding sides of DEF.
Answers
the angles should be congruent
sides should be dilated by a scale factor
Answer:
Option B. False
Step-by-step explanation:
If triangle ABC is similar to DEF then for the similarity of these triangles all angles should be similar or same.
In addition to the angles their corresponding sides should be in the same ratio, in other words sides should be dilated by a scale factor.
Therefore the given statement is false.
Option B. False is the answer.

Canada is the king of the doughnut world, as it has more doughnut shops per capita than any other country in the world. Tim Hortons, the most popular doughnut joint in Canada, had 3660 locations in Canada in 2015. If the population of Canada was approximately 35.75 million citizens in 2015, what was the number of Tim Hortons stores per capita in Canada in 2015?
Express your answer in scientific notation rounded correctly to three decimal places.
Answers
Per capita means the number of schools per person. There are more people than stores, so the number must be lower than 1.
To find the rate, we divide the total number of stores by the population.
3660 / 35750000 = .0001024 = 1.024 x 10^-4
Answer:
Number of Tim Hortons stores per capita is [tex]1.024\times 10^{-4}[/tex]
Step-by-step explanation:
Canada is having more doughnut shops per capita than any other country in the world means availability of Horton's store per person are more.
Number of Hortons stores in Canada = 3660
Population of Canada in 2015 = 35.75 million
In scientific notation population = [tex]35.75\times 10^{6}[/tex]
Now stores per person = [tex]\frac{3660}{35.75\times 10^{6}}[/tex]
(To calculate stores per capita we will divide number of stores by population of Canada)
Stores per capita = [tex]102.377\times 10^{-6}=1.024\times 10^{-4}[/tex]
So the answer is [tex]1.024\times 10^{-4}[/tex]
Sabra joins a cooking club for $8.50 and pays $6.25 each month. She also joins a movie club for $12 and pays $3.75 each month. Write an expression that represents the total amount of money Sabra spends on both clubs after m months. Then enter the simplified expression in the boxes.
Answers
To start we can write the following two expressions for her expenses.
8.5 + 62.5m and 12 + 3.75m
Then, adding the two expressions together will give us a combined expression of: 10m + 20.5
Total amount of money Sabra spends on both clubs = 20.50 + 10m
Amount paid to join the cooking club = $8.50
Monthly payment at the cooking club = $6.25
Payment for m months at the cooking club = 6.25m
Total money paid at the cooking club = 8.50 + 6.25m
Amount paid to join the movie club = $12
Monthly payment at the movie club = $3.75
Payment for m months at the movie club = 3.75m
Total money paid at the movie club = 12 + 3.75m
Total amount of money Sabra spends on both clubs = Total money paid at the cooking club + Total money paid at the movie club
Total amount of money Sabra spends on both clubs = 8.50 + 6.25m + 12 + 3.75m
Total amount of money Sabra spends on both clubs = 20.50 + 10m

We have m = 3, [tex]x_1 = 5[/tex], and [tex]y_1 = 10[/tex].
We plug in these values to get
[tex]y-10=3(x-5)[/tex].
We now rearrange to get this into slope-intercept form, [tex]y=mx+b[/tex], by solving for y.
[tex]y=3(x-5)+10\\y=3x-15[/tex]
y = 3x - 5
Explanation:
The equation of the line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept
We are given that the slope is 3. Therefore, the equation now is:
y = 3x + c
Now, we need to get the value of c. To do so, we will substitute with the given point (5,10) in the equation and solve for c as follows:
y = 3x + c
10 = 3(5) + c
10 = 15 + c
c = 10 - 15
c = -5
Based on the above, the equation of the line is:
y = 3x - 5

The original price was €280, but the price was discounted by 15%.
15% = 15/100 = 0.15.
15% of 280 is 0.15(280) = 42

What is the perimeter of AEB
Answers
18.5 ft
Explanation:
part (a): getting the value of AE:
The two triangles AEB and DEF are similar. Therefore, we can make use of the similar proportionality as follows:
AE / DE = BE / FE
Now, we have:
AE is the unknown we want to find
DE = AE + 2
BE = 7.8 ft
FE = 7.8 + 2.4 = 10.2 ft
Substitute in the above relation and get the value of AE as follows:
AE / DE = BE / FE
AE / (AE+2) = 7.8 / 10.2
10.2 AE = 7.8 AE + 15.6
2.4 AE = 15.6
AE = 6.5 ft
Part (b): getting the perimeter of AEB:
perimeter = AE + EB + AB
perimeter = 6.5 + 7.8 + 4.2
perimeter = 18.5 ft

what is the value of z, rounded to the nearest tenth? use the law of sines to find the answer.
A) 2.7 units
B) 3.2 units
C) 4.5 units
D) 5.3 units
Answers
[tex]\sf\dfrac{sin(X)}{x}=\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}[/tex]
We know what angle Y is and what side y is, so let's use that along with angle Z and side z:
[tex]\sf\dfrac{sin(Y)}{y}=\dfrac{sin(Z)}{z}[/tex]
Plug in what we know:
[tex]\sf\dfrac{sin(51)}{2.6}=\dfrac{sin(76)}{z}[/tex]
Multiply 'z' to both sides:
[tex]\sf\dfrac{sin(51)}{2.6}z=sin(76)[/tex]
Divide sin(51)/2.6 to both sides:
[tex]\sf z=\dfrac{sin(76)(2.6)}{sin(51)}[/tex]
Plug it into your calculator.
[tex]\boxed{\sf z\approx 3.2}[/tex]
The value of z is 3.2 units.
What is the law of sines?
The law of sine or the sine law states that the proportion of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides. It is additionally known as the sine rule.
For a triangle ABC the law of sine will be,
[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]
In triangle XYZ given here,
The law of sine can be written as,
[tex]\frac{x}{sinX} =\frac{y}{sinY} =\frac{z}{sinZ}[/tex]
here ∠Y and ∠Z is given so we write
[tex]\frac{y}{sinY} =\frac{z}{sinZ}[/tex]
y=2.6
∠Y=51°
∠Z=76°
sin51°≈0.78
sin76°≈0.97
[tex]\frac{y}{sinY} =\frac{z}{sinZ}[/tex]
[tex]2.6/0.78=z/0.97[/tex]
[tex]z=3.2 units[/tex]
