It is most definitely D, The volume of a cone is one-third of the volume of a cylinder.
How many solutions does the following system of equations have:
3x - 2y = 4
12x - 8y = 16
A. one solution
B. two solutions
C. no solution
D. infinite solutions
Answer:
D. Infinite solutions
Step-by-step explanation:
You divide the 2nd equation by 4.
3x - 2y = 4
(12x - 8y = 16)/4
3x - 2y = 4
3x - 2y = 4
This is exactly the same equation which means that the lines are forever intersecting which means that it has INFINTE solutions.
The population of a town is 14,000, and it grows at a rate of 4% per year. What will the population be in 6 years? What was the population 6 years ago?
Group of answer choices
about 87,360; about 11,400
about 17,714; about 11,064
about 14,560; about 12,602
about 17,360; about 10,870
The population 6 years ago was about 11,064.
The answer is (B) about 17,714; about 11,064.
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and x is the time period.
To solve this problem, we can use the formula for exponential growth:
A = P(1 + r)^t
where A is the final amount, P is the initial amount, r is the growth rate, and t is the time period.
Using the given values, we can plug in:
P = 14,000
r = 0.04
t = 6
To find the population in 6 years,
A = 14,000(1 + 0.04)⁶
A = 17,714
Therefore, the population in 6 years will be about 17,714.
To find the population 6 years ago, we can use the same formula with t = -6:
P = A/(1 + r)^t
P = 17,714/(1 + 0.04)⁻⁶
P = 11,064
Therefore, the population 6 years ago was about 11,064.
The answer is (B) about 17,714; about 11,064.

HELP ME PLEASE HURRY PLS
Answer:
A, no B, no, C, yes
Step-by-step explanation:
A. is not equivalent while b and c are equivalent.
a. isn't equivalent because 3/4 with the denominator of 12 is 9/12. Therefore, 9/12 isn't equal to 10/12.
b. is equivalent because -5/10 is shortened to -1/2. At the same time, -4/8 is also shortened to -1/2. Therefore, it is equivalent.
c. is equivalent as well because 10/8 into a mixed fractions is 1 2/8. Which simplified is equal to 1 1/4. Which, is equivalent to 1 1/4/

Answer:
B = y - mx
= 2 - (1/2)(-4)
= 2 - -2
= 4
y = (1/2)x + 4
Step-by-step explanation:
Answer:
You can choose the equation that you are familiar with.
[tex]y - 2 = \frac{1}{4} (x + 4)[/tex]
or
[tex]y = \frac{1}{4} x + 3[/tex]
Step-by-step explanation:
I'm not sure which formula you'd like me to use so I'll do both formula, the point-slope form and slope-intercept form.
We will be doing point-slope form first.
This is the point-slope form:
[tex]y - y_1 = m(x - x_1)[/tex]
Since we already have the given information needed (the slope and the points), we just need to plug in.
[tex]y - 2 = \frac{1}{4} (x + 4)[/tex]
Done!
-----------------------------------------------------
Let's do slope-intercept form now.
The is how the slope-intercept form looks:
[tex]y = mx + b[/tex]
Even though we have some given information, we need to acquire more, the b, also known as the y-intercept (the m, is also known as the slope.).
Let's find it by plugging in and solving the equation.
[tex]y = mx + b \\ 2 = \frac{1}{4}x + b \\ 2 = \frac{1}{4} ( - 4) + b \\ 2 = - 1 + b \\ \frac{ + 1 = + 1 \: \: \: \: \: \: \: \: \: \: \: }{3 = b \: \: \: \: \: \: \: \: \: \: \: } [/tex]
We found b (y-intercept), so now all we gotta do Is plug in for the final equation!
[tex]y = \frac{1}{4} x + 3[/tex]
Done!

2) [tex]\frac{9}{7} *[/tex] [tex]\frac{7}{9} * x = 21[/tex] [tex]* \frac{9}{7}[/tex]
∧ The fraction gets cross-multiplied and gets removed. 21 is then multiplied by 9/7
3) [tex]x = 21 * \frac{9}{7}[/tex]
4) [tex]7 * x =21 *( \frac{9}{7} * \frac{7}{1} )[/tex]
∧ The 9 / 7 gets multiplied by 7 / 1 to become 9. 7 is then multiplied by x
5) [tex]7x = 21 * 9[/tex]

3. Write an expression that only uses multiplication and that is equivalent to c reduce by 1/8 of x
Answer:
You can multiply 600 and 2 to get 1200 Pt2: c-(1/8x)
Step-by-step explanation:
since 1 third of 1800 is 600 and 1800-600=1200
1) You can multiply the following two numbers, by [tex]2[/tex] and by [tex]\frac{1}{3}[/tex]rent.

expression c +0.065c. What is this expression written in simplest form?
OA) 0.1650
O B) 1.0650
O C) 1.650
O DC (1 + 0.065)
The simplest form of the given expression is c(1+0.065). Therefore, option D is the correct answer.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, Hideki buys a skateboard that costs c dollars.
After 6.5% sales tax is added, the total cost can be expressed by the expression c +0.065c
The simplest form of the expression is
c +0.065c
= c(1+0.065)
= c(1.065)
= 1.065c
The simplest form of the given expression is c(1+0.065). Therefore, option D is the correct answer.

Answer:
x = 16°
Step-by-step explanation:
The triangles are approximately congruent
90 + 66 = 156
180 - 156 = 24
(x + 8) = 24
x = 16°
check
(16 + 8) = 24
90 + 66 + 24 = 180
Answer: x=16
Explanation:
The triangles shown are congruent and both of the triangles should have the sum of the angles as 180°. The equation should be (x+8)+66+90=180. Add the like terms to result with x+164=180. Subtract 156 to both sides to result with x=16.

The triangle in the question has 2 angles, 62 degrees and 52 degrees.
3 angles add up to 180 degrees, so missing angle is
