When a force of 270N is applied, the spring stretch by 7.5cm
Two variables are said to be directly proportional if as one variable increases/decreases, the other variables does the same by the same amount.
Let F represent the force and x represent the extension, hence:
F ∝ x
F = kx; k is the constant of proportionality
When F = 180, x = 5, hence:
180 = 5k
k = 36
F = 36x
When F = 270:
270 = 36x
x = 7.5 cm

Step-by-step explanation:
5) Add using Place-Value diagrams: 215 six + 43 six
As I understand, we want to perform the given sum by adding the correspondent place values.
Using this method, we will see that the value of the sum is 258.
First, we define the place values as the value that each "position" has, where the reference is the decimal point.
The first place at the left of the decimal points is the units digit.
The second is the tens digit, and so on.
With this, we can rewrite te twi given numbers as:
215 = 2*100 + 1*10 + 5*143 = 4*10 + 3*1Then the sum can be done as:
215 + 43
(2*100 + 1*10 + 5*1) + ( 4*10 + 3*1)
2*100 + (1 + 4)*10 + (5 + 3)*1
2*100 + 5*10 + 8*1 = 258
Then we have:
215 + 43 = 258

Step-by-step explanation:
I think it is 44.
if wrong forgive me.
hope this helps.
Answer:
44
Step-by-step explanation:
1. To round a number to the nearest 10, look at the ones-digit. If the digit is 5 or more, round up (raise the score). If the digit is 4 or less, round down (let it rest).
2. The ones-digit in 44 is 4 or less, meaning we round down. The 4 in the ones-place becomes zero, and therefore, rounds to 40.
Therefore, the answer is 44.

Dividing the current value by the previous value ALWAYS equals 1.05.
Since the growth rate is constant, it is linear.
Step-by-step explanation:
Answer:
ExponentialStep-by-step explanation:
The relationship is linear when the rate of change is constant. It means the sequence of the dependent variable forms an arithmetic sequence.
We see the the sequence of Projected Value is not arithmetic but geometric sequence with common ratio of 1.05.
It will have equation:

Jeanette obtained 32% for her statistics test, which was out of a total of 300 marks. How much should she score in the computer science test that is out of 200 marks in total if she is to get a proportionally weighted average of 46%?
Using weighted average, it is found that she should score 67% on the computer science test.
The weighted average is given by each proportion multiplied by it's score.In this problem, the proportions and scores are given by:
Proportion of 32% = 0.32 for a score of 300.Proportion of x for a score of 200.Proportion of 46% = 0.46 for a score of 300 + 200 = 500.Then
[tex]0.32(300) + 200x = 0.46(500)[/tex]
[tex]200x = 0.46(500) - 0.32(300)[/tex]
[tex]200x = 134[/tex]
[tex]x = \frac{134}{200}[/tex]
[tex]x = 0.67[/tex]
She should score 67% on the computer science test.

Find the Area of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
Hi,
Recall that the area of a parallelogram is the product of the base b and the height or "altitude" h. So the formula is : b * h. b = 20 here, and h = 6, so we get : 20 * 6 = 120.
Now we have to compute the area of the semicircle, remember the formula for the area of a circle is : πr² where r is the radius of the circle. If we watch the figure, we already have the value of the diameter d = 8. So the radius is equal to half the diameter : r = 8 /2 = 4
Now applying the formula we get : πr² = π * 4² ≈ 50.3 rounded to the nearest tenth place.
But we don't wont the area of the circle, we want half the area of it, since it's a semicircle : πr² / 2 ≈ 25.1 rounded to the nearest tenth place.
Now to get the whole area of the figure, we need to sum the area of the parallelogram with the area of the semicircle : 120 + 25.1 ≈ 145.1 rounded to the nearest tenth place.
Good Luck

Answer:
102°
Step-by-step explanation:
Angles in a straight line is added up to 180°
So,
Angle 1 + Angle 2 = 180°
Given that,
Angle 2 = 78°
We can find angle 1
Let us find,
Let the angle 1 be x
[tex]x+78=180\\x=180-78\\x=102[/tex]
As a and b lines are parallel,
Angle 1 = Angle 5 (Corresponding angles)
Also we already found the angle 1
So,
Angle 5 = 102°
