marta ha comprado una bicicleta que costaba 280 € pero le han hecho una rebaja del 15°/• cuanto ha pagado

Answers

Marta has paid €238.

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

This means the price was cut by €42.

280-42 = €238

Meghan has a beginning balance of $750 in her checking account. She writes a check for $150 and has a debit transaction of $135. What is her new balance?

Answers

her new balance is her new balance would be 435
heres my math
750-150-135=435

Her new balance is going to be 465 because if she has a balance of 750 and than she writes a check for 150, so you subtract
750-150
Than she has a debit transaction of 135, so you subtract
600-135 giving you 465

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

We can change the law of sines a little bit to match our problem.

[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]

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

The correct answer is 1.024 x 10^-4.

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]

Answers

It's easiest to start with the point-slope form of an equation, [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is the point given.

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]

Answer:
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

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

Answer: The simplified express is 10m + 20.5 where m represents the total number of months.

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

Answer:
The car can travel 66 miles using 5.5 liters of gasoline

Explanation:
We are given that:
The expression 12*g is used to evaluate the number of miles the car can travel using g liters of gasoline.
Therefore:
miles = 12*g

Now, we are given that the liters of gasoline = 5[tex] \frac{1}{2} [/tex] = 5.5 liters.
To get the number of miles, all we have to do is substitute with the given liters in the above expression as follows:
miles = 12*g
miles = 12 * 5.5
miles = 66 miles

What is the perimeter of AEB

Answers

Answer:
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
