Answer:
No, the rate is not proportional.
Step-by-step explanation:
If there are 45 marbles in 9 bags, we can assume that there are 5 marbles in each bag.
Going by that rate, we can do 5 * 36 = 180, NOT 150.
Thus, the rate is not proportional.
Another way to solve would be to do 45/9 and 150/36. If the rate is proportional, the answer for both should be the same.
However, 45/9=5 and 150/36=4.16666666667.
Those two answers are NOT equal.
Thus, the rate is not proportional.

The triangles below are similar find Y
Answer:
15Step-by-step explanation:
y = 15
The ratio of the corresponding sides of a similar triangle will be constant. Then the length of y will be 15 units.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
If the two triangles are similar, the ratio of the corresponding sides will be constant.
Then the ratio will be
22 / 10 = 33 / y = x / 12
From first two terms, we have
22/10 = 33/y
y = 15 units

The two circles have different diameters in the ratio 5:3.
(A) Calculate the radius of circle B if circle A has a radius of 35mm
(B) Calculate the area of circle A giving your answer to the nearest cm squared.
Answer:
a) 21 mm
b) 39 cm^2
Step-by-step explanation:
a) The ratio of the diameter from A to B is 5:3
Let the diameter of B be x
If 35 is the radius of A, then its diameter is 35 * 2 = 70 mm
Thus;
5/3 = 70/x
5* x = 70 * 3
5x = 210
x = 210/5
x = 42 mm
So the radius of circle B will be 42/2 = 21 mm
b) The area of circle A
Mathematically we apply the area of a circle formula here
A = pi * r^2
A = 22/7 * 35 * 35
A = 3,850 mm^2
To convert this to cm^2, we will
need to divide by 100
That would be 3850/100 = 38.5 cm^2 = 39 cm^2

An architect draws a plan for a wheelchair ramp on the plan, the ramp is 2cm high and 24cm long what might the dimensions of the actual ramp be (use equivalent ratios)
Answer:
[tex]Height = 30cm[/tex]
[tex]Length = 360cm[/tex]
Step-by-step explanation:
Given
Scale Measurement
[tex]Height = 2cm[/tex]
[tex]Length = 24cm[/tex]
Required
Determine the possible actual measurement
First, calculate the equivalent ratio.
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{24cm}{2cm}[/tex]
[tex]Ratio = 12[/tex]
To do this, we pick a scale factor.
Assume the scale factor is 15.
The actual measurement will be:
[tex]Height = 2cm * 15[/tex]
[tex]Height = 30cm[/tex]
[tex]Length = 24cm * 15[/tex]
[tex]Length = 360cm[/tex]
When the scale ratio is calculated, we have:
[tex]Ratio = \frac{Length}{Height}[/tex]
[tex]Ratio = \frac{360cm}{30cm}[/tex]
[tex]Ratio = 12[/tex]
Note that both have the same equivalent ratios of 12.
So, whatever the scale ratio you use, the equivalent ratio will be the same

Quadrilateral MNPQ has vertices M(0,6), N(4,4), P(6. – 1), and Q(2,0). Determine the coordinates of the vertices of the image of
the quadrilateral after the translation (x,y) → (x – d4, y +1).
Answer: M(-4,7)P(0,5)Q(-2,1)
Step-by-step explanation:
The translation is telling you to subtract each x value by 4 and add 1 to each y value.

Answer:
For the first: [tex]x=-23[/tex] and [tex]x=17[/tex]
For the second: [tex]x=5[/tex]
Step-by-step explanation:
Answer:
x=17 for the first and x=5 for the second.
Step-by-step explanation:
First picture
Opposite angles of two intersecting lines are equal.
So the angle opposite the 100 degree angle on line c is also 100.
Since a, b, and c are all parallel, the angles made by the intersecting line r, are also all equal (these are corresponding angles).
So 5x + 15 = 100
5x = 85
x = 17
Second picture
Adjacent angles add up to 180 degrees. So the angle opposite 52 is 180-52=128.

A team of 6 people is to be chosen from 8 men and 6 women. Find the number of different teams that may be chosen if
(a) there are no restrictions,
(b) there are a husband and wife who must not be seperated,
9514 1404 393
Answer:
a) 3003
b) 1419
Step-by-step explanation:
a) With no restrictions, the problem amounts to counting the number of combinations of 14 people taken 6 at a time. That is ...
14!/(6!(14-6)!) = 3003 . . . teams with no restrictions
__
b) With the restrictions, there are two cases:
(i) all 6 people are taken from the 12 that exclude the couple. That number of combinations is ...
12!/(6!(12-6)!) = 924
(ii) 4 people are taken from the 12 that exclude the couple, and the couple fills the last two team slots. That number is ...
12!/(4!(12-4)!) = 495
The sum of the counts of these two cases is ...
924 +495 = 1419 . . . teams with inseparable couple

A salesperson earns $450 per week plus 15% of her weekly sales. The
expression representing her earnings is 450 +0.15x. Which of the following
describes the sales necessary for the salesperson to earn at least $600 in
one week?
Answer:
If a sales person wants to earn $600 in 1 week they have to make $1000 dollar sale or a bunch of sales that can make $1000
Step-by-step explanation:
Because $600 - $450 gives you $150, and $150 is 15% of her sales to if we were to divide $150 by 0.15 ( 15% in decimal for ) we would get $1000 meaning 15% of 1000 is 150.
Hope this helps :)
