How do you compare proportional relationships
Answer: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
Step-by-step explanation:
You have given an equal sided triangle with side length a. A straight line connects the center
of the bottom side to the border of the triangle with an angle of α. Derive an expression for
the enclosed area A(α) with respect to the angle (see drawing
Answer:
First case;
α < 90°
The area of the shaded triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)
Second case;
α > 90°
The shaded area of the triangle = 1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4
Step-by-step explanation:
First case;
α < 90°
The given parameters are;
The type of triangle = Equilateral triangle
The length of the sides of the triangle = a
The area of the triangle = 1/2×a×b×sinC
Where;
a and b are two legs (sides) of the triangle and C is the included angle
e/(sin(α)) = a/(2sin(120 - α)) = f/(sin60)
f = a·sin(60)/(2sin(120 - α))
The area of the triangle = 1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α)
By an online application, we have
1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α) = 1/8·a²·sin(60)sin(α)csc(120 - α)
The area of the triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)
Second case;
α > 90°
The shaded area of the triangle = The area of the equilateral triangle - The unshaded area of the triangle
With an online tool, we have;
The shaded area of the triangle = (a²·√3)/4 - 1/8·a²·sin(60)sin(180 - α)csc(120 - (180 - α)
The shaded area of the triangle = 1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4
Subtract - 5x ^ 2 + 10x - 1 from 6x ^ 2 - x + 3 .
Answer:
11x^2-11x+4
Step-by-step explanation:
(6x ^ 2 - x + 3)-( - 5x ^ 2 + 10x - 1 )
6x^2-x+3+5x^2-10x+1
11x^2-11x+4
So the answer is 11x^2-11x+4

(x + 12)^2 = 9x + 12 = ± 3x = ± 3 - 12x = - 9, x = - 15What is the slope of the line
Answer:
[tex]\huge\boxed{\frac{1}{2}}[/tex]
Step-by-step explanation:
In order to find the slope of a line, we need to find it’s rise over it’s run.
To do this, we need to find the change in y, and divide that by the change in x between any two given points.
[tex]\frac{\Delta y}{\Delta x}[/tex]
Two points on this graph that we can compare are are (-1, 3) and (1, 4).
From -1 to 1 is 2 points. So, the change in x is 2.
From 3 to 4 is 1 point. So, the change in y is 1.
Divide the change in y by the change in x:
[tex]1 \div 2 = \frac{1}{2}[/tex]
So the slope is 1/2.

If Lily got 18 questions right on a 20 questions
test, what percentage of the questions did she
get wrong?
Answer:
She got 10% of the questions wrong !
Step-by-step explanation:
To solve this problem I used cross multiplication
[tex]\frac{x}{100}= \frac{18}{20}[/tex]
18 x 100 =1800
1800 / 20 = 90
Since they are asking what she got wrong, not what she got right, you just need to subtract.
100% - 90% = 10%
hope this helped !
Answer:
10%
Step-by-step explanation:
18/20 Questions = 0.9 or 90% she got right
2/20 Questions = 0.1 or 10% she got wrong

A game decreased in price by
1/3
After the reduction it was priced at £26.
What was the original price of the game??
Answer: £78
Step-by-step explanation
It decreased by 1/3 and after the reduction it was £26 so you have to get the other 2/3 so you multiply £26 by 3 to get the 3/3 that you need that will give you £78.
26 × 3 = £78
What is |5.4|?
What is the opposite of 10?
Answer:
-10
Step-by-step explanation:
Answer:
1. 5.4
2. The additive inverse is the negative value, -10.
The multiplicative inverse (reciprocal) is 1/10.
Step-by-step explanation:
1. Since the value within the absolute value is not negative then the value remains the same.
2, The opposite of positive 10 could be -10. The reciprocal is 1/10.
A stock loses $1.50 each day over a five-day period. What is the total change in the value of the stock at the end of five days? (remember to have two numbers after the decimal)
Given:
A stock loses $1.50 each day over a five-day period.
To find:
The total change in the value of the stock at the end of five days.
Solution:
Stock loses each day = $1.50
We know that, loss or reduction represented as negative change.
So, change in the value of the stock per day = -$1.50
Change in the value of the stock in 5 days = 5×(-$1.50)
= -$7.50
Therefore, the change in the value of the stock at the end of five days is -$7.50. It means, the value of the stock loses $7.50 at the end of five days.

Which of these is a factor of 10?
A. 20
B. 2
C. 4
Answer:
B. 2
Hope this helps!
Step-by-step explanation:
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

Luis has a pyramid shaped plant pot. It has a square base with a side length of 36 cm, and the height of the pot is 36 cm. Luis wants to fill the pot with soil so that the soil takes up 75% of the pot's volume. How far up the pot will the soil reach?
Answer:
The required volume, if he wants to fill 75% of the pot's volume, is 11664cm³
Step-by-step explanation:
The volume of a pyramid is given as
[tex]V = \frac{1}{3} \times A \times h[/tex]
Where V is the pot's volume, A is the base area and h is the height.
Our base is a square, so the base area, if s denotes the side length, would be s x s.
s = 36cm, therefore we have A = 36cm X 36cm = 1296cm².
The height is given as 36cm, therefore we have our volume to be:
[tex]V = \frac{1}{3} \times 1296cm^2 \times 36cm[/tex]
[tex]V = 15552cm^3[/tex]
Since Luis wants to fill 75% of the pot's volume with soil. Then it will take
[tex]\frac{75}{100} \times 15552cm^3 = 11664cm^3 [/tex]
Thus, the required volume, if he wants to fill 75% of the pot's volume, is 11664cm³

Answer:
9 or 23
Step-by-step explanation
It depends of if D is an endpoint or in the middle.
If D is an enpoint, the length of BM is 16-7=9.
If it’s a midpoint, then BM is 16+7=23.
