Answers
Answer:
C. 1324.7 cm³
Step-by-step explanation:
Volume of cylinder = πr²h
π = 3.14
radius (r) = ½ of 15 = 7.5 cm
Height (h) = 7.5 cm
Plug in the values
Volume = 3.14*7.5²*7.5 = 1324.7 cm³

Tyler orders a meal that costs $15. The sales tax rate in Tyler's county is 6.6%. Write an equation to represent the relationship between the original cost of the meal and the cost after the sales tax. Use x for the original cost for the meal and y for the cost after sales tax.
Answers
Answer:
Step-by-step explanation:
y = (1.066)x
The equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x
How to calculate the sales tax?The sales tax is the amount charged on the price of goods and services.
Let x be the original cost for the meal
Let y be the cost after the sales
If the sales tax rate in Tyler's county is 6.6%, the tax charged is expressed as:
0.066 of theoriginal cost
0.066x
Cost after tax = original cost + tax
Cost after tax = x + 0.066x
y = 1.066x
Hence the equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x

Equation: y = 2x
Graph: see attachment
Step-by-step explanation:
Pieces of paper = x
Number of Valentines = y
The equation is a proportional equation and can be represented as y = kx
k is the constant of proportionality
k = y/x
Using (2, 4),
k = 4/2 = 2
To find the equation, substitute k = 2 into y = kx
Thus:
y = 2x

Answers
Answer:
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.

[tex] y = 4 [/tex]
Step-by-step explanation:
Given:
[tex] y = \frac{7x + 1}{3x - 6} [/tex],
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into [tex] y = \frac{7x + 1}{3x - 6} [/tex]
[tex] y = \frac{7(5) + 1}{3(5) - 6} [/tex]
[tex] y = \frac{35 + 1}{15 - 6} [/tex]
[tex] y = \frac{36}{9} [/tex]

How can we get system B for system A?
And
Are the systems equivalent?
Answers
Answer: Subtract the equations in system A.
=============================================================
Explanation:
The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.
There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.
For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y
So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.
Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.
Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.

After 24h will be 108p
Each c is 6m
12 laps
Step-by-step explanation:
36 - 33 = 3
33 - 30 = 3
30 - 27 = 3
27 - 3 = 24
12h = 36p
12h × 3 = 36h
So 36p need to × 3 too
36p × 3 108p
Because 3c to 5c, 18m to 30m need 12m. There was no 4c so the 12m need to divide two. 12m ÷ 2 = 6m.
So each c is 6.
72 ÷ 6 = 12
The six is from the last question.
