Answer:
no
Step-by-step explanation:
I calculated
No because something proportional can't have a y-intercept, the 3 is the y intercept so your statement is not proportional.

Step-by-step explanation:
75×50/100= 37.5$
37.5×6/100=225/100=2.25$
37.5+2.25= 39.75$
Solve for x when y=16.
3x+7=y
Answer: 3
Step-by-step explanation:
3x + 7 = y
3x + 7 = 16
*subtract 7 from both sides because inverse operations*
3x = 9
*divide both sides by 3 because inverse operations*
x = 3
How do I do this? Anyone help!
Given:
Number of sides = 7
Apothem = 8 meters
Side length = 7.7 meters
To find:
The area of the regular polygon.
Solution:
We know that,
Area of a regular polygon is
[tex]A=\dfrac{1}{2}pa[/tex] ...(i)
where, p is perimeter and a is apothem.
Perimeter of a regular polygon is the product of number of sides and side length.
[tex]p=7\times 7.7[/tex]
[tex]p=53.9[/tex]
Substituting p=53.9 and a=8 in (i), we get
[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]
[tex]A=(53.9)(4)[/tex]
[tex]A=215.6[/tex]
Therefore, the area of the regular polygon is 215.6 m².
Gerard concluded that the triangle with sides StartRoot 95 EndRoot feet, 8 feet, and StartRoot 150 EndRoot cannot be used as a building frame support on the house because it is not a right triangle. How did Gerard come to that conclusion? Explain.
Answer:
Check explanations for answer
Step-by-step explanation:
Here, we want to find out how Gerard came to the conclusion
For him to arrive at this conclusion, then we should consider the lengths given if they form a right triangle and are suitable for the building frame
From the lengths that we have
If we square the longest length, then the sum of the squares of the two other lengths should be the same as it is
This is in obedience to Pythagoras’ theorem
However, this does not hold
√(150)^2 is not equal to 8^2 + (√(95))^2)
and so since this does not work, then the triangle is not right-angled and cannot be use as the frame
Answer:
Step-by-step explanation:Sample Response: Gerard determined that the squares of the two smaller sides did not equal the square of the longest side. The side lengths did not create a true statement of the Pythagorean theorem.

Convert the equations form standard form to slope intercept form 8x-10y=20
Answer:
y=4/5x-2
Step-by-step explanation:
8x-10y=20
-10y=-8x+20 subtract 8x from both sides
x=4/5x-2 divide everything by -10

How do i find the values of of both x and y in a quadrilateral?
Answer:
n stands for the number of sides, which is 4.
To find the sum of the angles, subtract 2 from the number of sides and multiply by 180.
Add all the angles together and set that equal to 360 to solve for x.
Plug 32 ° in for x to find the measures of the angles.
Mr. Gurung sold a bicycle for Rs 18,816 and made a profit of 12%. if he wants
to increase his profit by 3%, at what price should be sell the bicycle
please help me:(
Answer:
Rs. 23520
Step-by-step explanation:
Given that :
At 12% profit ; sales price = 18,816
At (12 + 3)% profit ; sales price = x
Hence,
0.12 = 18,816
0.15 = x
Cross multiply ;
0.12x = 0.15 * 18816
0.12x = 2822.4
x = 2822.4 / 0.12
x = 23520
Hence, sales price for a 3% increaa in profit should be Rs. 23520

1. The total cost of 3 cups of hot chocolate is $8.25. Assume the total cost
of hot chocolate y varies directly with the number of hot chocolate
ordered x. What is the cost of one hot chocolate? *
O A. $0.36
O B. $8.25
O C. $2.75
O D. $3.00
Answer:
C) $2.75
Step-by-step explanation:
8.25/3 = 2.75
Answer:
C. $2.75
Step-by-step explanation:
3 cups of chocolate and each is $8.25. To solve this, the equation would be:
$8.25/3
This is equal to $2.75, so that is the answer!
( Also, 2.75 * 3 = 8.25, so it's correct! )

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese
Answer:
y = 4.25x
Step-by-step explanation:
Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as
4.25 is the cost for 1 pound of Cheddar cheese
Let the cost of the equation be y as required from the question.
y = cost of the cheddar cheese
x is the weight value in pounds of the Cheddar cheese.
The equation can be best represented as
y = 4.25x
In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.
