It is most definitely D, The volume of a cone is one-third of the volume of a cylinder.
2. A person makes $1,800 per month, but 1/3 of that amount goes to her rent. Ehat two numbers can you multiply to find out how much she has after paying her rent?
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.
2) The expression that only uses multiplication and that is equivalent to [tex]c[/tex] reduced by [tex]\frac{1}{8}\cdot x[/tex] is [tex]c = \frac{1}{8}\cdot x[/tex].
How to analyze and determine linear equations1) The amount of left is found by following formula, that is, the salary minus rent costs, both expressed in dollars:
[tex]x = \left(1-\frac{1}{3}\right)\cdot 1800[/tex]
[tex]x = \frac{2}{3} \cdot 1800[/tex]
[tex]x = 1200[/tex]
You can multiply the following two numbers, by [tex]2[/tex] and by [tex]\frac{1}{3}[/tex], to find out how much she has after paying her rent. [tex]\blacksquare[/tex]
2) This case is represented by a linear expression of the form:
[tex]c = r\cdot x[/tex] (1)
Where:
[tex]x[/tex] - Independent variable[tex]c[/tex] - Dependent variable[tex]r[/tex] - Proportionality ratioIf we know that [tex]r = \frac{1}{8}[/tex], then the expression is [tex]c = \frac{1}{8}\cdot x[/tex].
The expression that only uses multiplication and that is equivalent to [tex]c[/tex] reduced by [tex]\frac{1}{8}\cdot x[/tex] is [tex]c = \frac{1}{8}\cdot x[/tex]. [tex]\blacksquare[/tex]

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/

What is What is the equation of the line that passes through the point (−4,2) and has a slope of 1/4 (1 over 4 is a fraction btw)
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!

using pt-slope form, we get [tex]y - (-9) = \frac{-5}{4}(x-4)[/tex]. Using the Distributive Property and Addition Propert of Equality, we can simplify this equation into [tex]y = \frac{-5}{4}x + 5[/tex] by factoring -5/4 into (x-4) and subtracting 9 from both sides.
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. 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 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.
