Answer:
30 pencils
Step-by-step explanation:
Given :
Number of pencils shared = 40
Sharing ratio = 2 : 6
Nimah's share = (2 / sum of ratio) * number of pencils
Nimah's share = (2 / 8) * 40
Nimah's share = 80 / 8
Nimah's share = 10 pencils
Jack's share = total number - Nimah's share
Jack's share = 40 - 10
Jack's share = 30
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.
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
Which fraction is equivalent to eight twelfths?
Answer:
2/3
Step-by-step explanation:
Pretty simple to find. Divide both the top and the bottom by 4, and see that it makes 2/3. Easy way to figure out any of these is just to simpliy them. Like 10/12 would equal 5/6

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
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.

The linear model y equal 0.6 x plus 45 represents the number of pairs of sandals sold, y, for a given outdoor temperature of x degrees at a certain shoe store. How many pairs of sandals should the company expect to sell if the outside temperature is 90 degrees?
Answer:
99
Step-by-step explanation:
Given the linear equation:
y = 0.6x + 45
x = outdoor temping degrees ; y = number of pair of sandal sold
Number of pairs of sandals the company expect to sell if the outside temperature is 90 degrees?
y = 0.6(90) + 45
y = 54 + 45
y = 99
The expected number of sandals to sale will be 99

Answer:280
Step-by-step explanation:14 x 20 = 280
Answer:
235 cm
Step-by-step explanation:
First, find the area of the whole rectangle (bxh)
14x20=280
Next, find area of the missing piece
5x9=45 ( to find this, 14-9, times 20-11)
Finally, subtract the missing piece from the total rectangle
280-45=235

Answer:The speed stays the same as the car travels a distance of 40 miles in one hour.
Step-by-step explanation:
The meaning of “constant speed” is when the speed of an object remains the same speed, therefore it does not increase nor decrease, it stays at a constant speed.

The Econo Motel charges 260 for 4 nights. At that rate, how many would 7 nights cost?
Answer:
$455
Step-by-step explanation:
First, find the cost of one night. It is given that it costs $260 for 4 nights. Simply divide 260 with 4:
260/4 = 65
It costs $65 per night.
Next, find the cost for 7 nights. Simply multiply 65 with 7:
65 x 7 = $455
$455 would be the cost for 7 nights.

Which pairs of polygons are similar? Plz help
Answer:
Option (1) and (3)
Step-by-step explanation:
Properties for the similarity of two figures,
1). Angles of the figures should be same.
2). Corresponding sides of both the figures should be proportional.
Since all the pairs have same angles, we will use the second property to prove these polygons similar.
Option (1)
If both the polygons are similar,
[tex]\frac{3}{7.5}=\frac{5}{12.5}[/tex]
[tex]\frac{1}{2.5}=\frac{1}{2.5}[/tex]
Since, sides are proportional,
Both the polygons are similar.
Option (2)
If the given triangles are similar,
Ratio of the sides of both the triangles will be proportional,
[tex]\frac{18}{8}= \frac{24}{15}[/tex]
[tex]\frac{19}{4}=\frac{8}{5}[/tex]
But [tex]\frac{19}{4}\neq \frac{8}{5}[/tex]
Therefore, triangles are not similar.
Option (3)
If both the rectangles are similar,
[tex]\frac{22}{13.75}=\frac{16}{10}[/tex]
1.6 = 1.6
True.
Therefore, both the rectangles are similar.
Option (4)
If both the triangles are similar,
[tex]\frac{8}{5}=\frac{7}{5}[/tex]
1.6 = 1.2
But 1.6 ≠ 1.2
Therefore, these triangles are not similar.

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

Give y = 3x - 1, if x decreases by 2, how much does y change ?
is y= -2/5 x + 3
y=2/5 x +3 parallel ?
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.

Four subtracted from four times the smaller is equal to the larger number. Twice the larger number equals six times the smaller number. What are the numbers?
Answer:
12 and 4
Step-by-step explanation:
We could set up two equations with the given information.
Let a be the larger number, and b be the smaller number.
4b - 4 = a (Four subtracted from four times the smaller is equal to the larger number.)
2a = 6b (Twice the larger number equals six times the smaller number.)
With the 1st equation, we could substitute a = 4b - 4 into the second equation.
We get
2(4b-4) = 6b
8b - 8 = 6b
2b = 8
b = 4
Substituting back into the first equation,
a = 4(4) - 4 = 12
Therefore the two numbers are 12 and 4.
the answer is four and twelve
