Answer:

the answer is 75%

Step-by-step explanation:

To write 3/4 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % . 3/4 * 100 = 0.75 * 100 = 75%. And finally we have: 3/4 as a percent equals 75%.

The percentage value of 3/4 is 75%.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

The given number is 3/4,

To convert 3/4 in percentage, use percentage property,

1%=1/100

⇒1=100%

⇒3/4= 75%

So 75% is the percentage value of 3/4.

It is most definitely D, The volume of a cone is one-third of the volume of a cylinder.

Answer:a: y=4.5+0.75x

B: y=2.5+1.25x

C: 7.5

Step-by-step explanation:

The simplest form of the given expression is c(1+0.065). Therefore, option D is the correct answer.

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:

9x+6

Step-by-step explanation:

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!

Answer:

x (Total number of chocolates) = 27

6 milk chocolates

Step-by-step explanation:

1)  [tex]\frac{7}{9} * x = 21[/tex]

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]

6) Simplify 21 * 9 to 189

7) [tex]7x = 189, becomes, \frac{7x}{7} = \frac{189}{7}[/tex]

8) Simplify to [tex]x = 27[/tex] , where x = total number of chocolates

9) [tex]27 - 21 = 6[/tex] milk chocolates

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 6 years ago was about 11,064.

The answer is (B) about 17,714; about 11,064.

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.

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].

1) 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:

If 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:

D. NEITHER

Step-by-step explanation:

The triangle in the question has 2 angles, 62 degrees and 52 degrees.

3 angles add up to 180 degrees, so missing angle is

62+52 +x = 180

180 - 114 = 66 degrees

None of the triangles have the same angles, thus none of similar.
