Helena is going for a holiday to France. She changes 900 Singapore Dollars (SGD) into Euros (EUR) with no commission charged. The exchange rate between EUR and SGD is:

1 EUR = 1.49 SGD



(a) Calculate the value of 900 SGD in EUR to the nearest whole number.



At the end of Helena’s holiday in France she has 155 EUR. She converts this back to SGD at a bank, which does not charge commission, and receives 227.85 SGD.

(b) Find the exchange rate of this second transaction.

Answers

Answer:

a) 900 SGD = 604.03 EUR

b) 1 EUR = 1.47 SGD

Step-by-step explanation:

It is given that:

1 EUR = 1.49 SGD

a) Value of 900 SGD.

1 SGD = [tex]\frac{1}{1.49}[/tex]

900 SGD = [tex]\frac{1}{1.49}*900[/tex] = 604.03 EUR

b) 155 EUR = 227.85 SGD

1 EUR = [tex]\frac{227.85}{155}[/tex]

1 EUR = 1.47 SGD

Thus,

a) 900 SGD = 604.03 EUR

b) 1 EUR = 1.47 SGD

Enter the equation that describes the line in slope-intercept form. The points (7, 9) and (2, −9) are on the line y = .

Answers

Given:

A line passes through two points (7, 9) and (2, −9).

To find:

The slope intercept form of the line.

Solution:

A line passes through two points (7, 9) and (2, −9), so the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-9=\dfrac{-9-9}{2-7}(x-7)[/tex]

[tex]y-9=\dfrac{-18}{-5}(x-7)[/tex]

[tex]y-9=\dfrac{18}{5}(x-7)[/tex]

Using distributive property, we get

[tex]y-9=\dfrac{18}{5}(x)-\dfrac{126}{5}[/tex]

[tex]y=\dfrac{18}{5}(x)-\dfrac{126}{5}+9[/tex]

[tex]y=\dfrac{18}{5}x+\dfrac{-126+45}{5}[/tex]

[tex]y=\dfrac{18}{5}x-\dfrac{81}{5}[/tex]

Therefore, the slope intercept form of the line is [tex]y=\dfrac{18}{5}x-\dfrac{81}{5}[/tex].

Un tren de carga va a una velocidad constante de 60 km/h y pasa por un túnel de 340 m de largo. ¿Cuánto mide el tren, si es que para cruzar completamente el túnel se demora tres cuartos de minuto?

Answers

Answer:

the length would be 410.15m

Step-by-step explanation:

The computation of the length is as follows;

Length = 340m

Let us assume x be train length

Now

the distance traveled by the train is  (L + x)

d = L + x

v = 60 km ÷ h

= 16.67 m / s

And,

t = (3 ÷ 4) (60)

= 45s

Now

d = vt

L + x = (16,67) (45)

x = (16,67) (45) - 340m

x = 410.15m

Hence, the length would be 410.15m

Answers

Complete Question

Oh sunday sheldon bought 4 1/2 kg of plant food,he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.How many kg of palnt food did sheldon have left?

Answer:

2 7/12 kg

Step-by-step explanation:

Oh sunday sheldon bought 4 1/2 kg of plant food,he used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.How many kg of palnt food did sheldon have left?

Step 1

We add up the kg of plant food that he used

He used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plant.

The total amount of plant food that he used = 1 2/3 kg + 1/4 kg

Lowest Common Denominator 12

1 + (2/3 + 1/4)

1 + (8 + 3/12)

1 11/12 kg of plant food

Hence he has used 1 11/12 kg of plant food

Step 2

The amount of plant food that he had left is calculated as:

Amount of plant food Sheldon bought - Amount of plant food he used

Amount of plant food Sheldon bought = 4 1/2 kg

The amount of plant food that he had left = 4 1/2 kg - 1 11/12

4 - 1 + (1/2 - 11/12)

Lowest common denominator = 12

3 + ( - 5/12)

= 2 7/12 kg

Therefore, the kg of plant food that sheldon had left = 2 7/12 kg

A student has $78 in his checking account. If the student spends $12 on lunch, which number could be combined with the amount left in the account to make zero? –90 –78 –66 –12

Answers

Given:

A student has $78 in his checking account.

The student spends $12 on lunch.

To find:

The number that could be combined with the amount left in the account to make zero.

Solution:

We have,

Amount in account = $78

Money spend on lunch = $12

Remaining amount = Amount in account - Money spend on lunch

                               = $78 - $12

                               = $66

Remaining amount is $66. So, -66 could be combined with the amount left in the account to make zero.

[tex]66+(-66)=66-66=0[/tex]

Therefore, the correct option is C.

is y= -2/5 x + 3
y=2/5 x +3 parallel ?

Answers

Answer:

No

Step-by-step explanation:

They are intercepting each other

Answer: No, y = -2/5x + 3 and y = 2/5x + 3 are not parallel.

Step-by-step explanation:

Generally speaking, parallel lines are lines that do not intersect. This means that they always have the same slope and different y intercepts, like y = 4x + 3 and y = 4x - 5.

On the other hand, perpendicular lines are lines that intersect at 90° angles. They have inverse slopes, or slopes that are the reciprocals of each other. Inverse slopes should be completely opposite to each other, which means flipping the numerator and the denominator and also changing the sign. One example is y = 2x + 4 and y = -1/2 x + 4.

Back to lines y = -2/5x + 3 and y = 2/5x + 3, they are not parallel because they have different slopes and the same y intercept. They are also not perpendicular because their slopes are not the inverses of each other.

You can also tell if the lines are parallel by inserting them into Desmos and seeing how they look. In this case, the lines intersect, and so once again they are not parallel.

Your sister is getting married this summer and she asked you to help her select a D.J. for the big event. You called around and found that Dave the D.J. charges a $150.00 set-up fee, plus $10.50 per hour. You discover Marvin’s Mobile Music Machine has a $135.00 set-up fee, plus $15.00 per hour.

Which D.J. will you recommend to your sister? Be sure to clearly support your recommendation mathematically.

Answers

It depends on how long the wedding is. Marvin has a $15 lower flat fee but a $4.50 more expensive hourly fee. Therefore, if the wedding is longer than 15/4.50=3.33 hours, it would make more sense to go with Dave. If the wedding is shorter than 3.33 hours, it makes more sense to go with Marvin.

Answer:

f^-1 (x) = 2X + 8

Step-by-step explanation:

Let's make f(x) = y

Y = X/2 - 4

So to find the inverse, switch the y with the x like so:

X = Y/2 - 4 (isolate the Y value)

X + 4 = Y/2 (multiply both sides by 2)

2(X + 4) = Y

Y = 2X + 8

So f^-1 (x) = 2X + 8
