Step-by-step explanation:

I rlly think it is c.12-×+4

Answer:

C.

Step-by-step explanation:

For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

3/a x-4=20

By clearing "x" we have:

Adding 4 to both sides of the equation:

3/a x = 20 + 4

Multiplying by a/3 on both sides of the equation:

x=24a/3

x=8a

So, x=8a

Answer:

x=8a

Answer:

-3y^8+18y^5+10y is the standard form of the equation. The leading coeficients are -3, 18 and 10

Step-by-step explanation:

The highest power awlays goes at the beginning of the equation. In this situation the highest power is 8, followed by 5 and then by 1. Usually the 1 as a power is not written. The leading coeficients are the numbers infront each term. If there is -4xy, the leading coeficient is -4.

Answer:

The scale of dilation is 2.5

Step-by-step explanation:

K · ( 0, 0 ) = ( 0 , 0 )

k · ( 0 , 4 ) = ( 0 , 10 )

k · ( 6, 0 ) = ( 15, 0 )

k = 15/6 = 10/4 = 2.5

The scale of dilation is 2.5

Answer:

-80

Step-by-step explanation:

5×(-6 - 10)

5×(-16)

-80

solve by using BODMAS rule

Answer: -80

First step is to calculate everything inside the brackets = [3× (-2) -10] = [(-6) - 10] = [(-16)] then we now multiply the number outside the brackets with the number inside the brackets which = 5[-16] = -80.

Answer:

C(r) = 100 + 55r

C(6) = $430

Step-by-step explanation:

Fixed charges = $100

Charges per room = $55

A. function that represents the total amount he charges for designing a certain number of rooms.

Let

r = number of rooms

C = Total amount charged

C(r) = 100 + 55r

The function is C(r) = 100 + 55r

B. What is the value of the function for an input of 6, and what does it represent

C(r) = 100 + 55r

When r = 6

C(6) = 100 + 55 * 6

= 100 + 330

= 430

C(6) = $430

This means that the amount charged for 6 rooms is $430

The equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The three figures are shown in the picture.

After analysis:

2(3) + 1  = 7

2(4) + 1  = 9

2(5) + 1  = 11

The standard form:

y = 2(x+2) + 1

y = 2x + 4 + 1

y = 2x + 5

Thus, the equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

$12.84/6 = $2.14 per ounce

Answer:

111

Step-by-step explanation:

It is given that the student to faculty ratio at a small college is 17:3.

Let number of students and faculty members are 17x and 3x respectively.

It is given that total number of students and faculty is 740.

[tex]17x+3x=740[/tex]

[tex]20x=740[/tex]

Divide both sides by 20.

[tex]x=37[/tex]

Number of student [tex]=17\times 37=629[/tex]

Number of faculty members [tex]=3\times 37=111[/tex]

Therefore, there are 111 faculty members at the college.

The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

Two ratios form a proportion if the simplified form of both ratios comes out as the same ratio. Suppose that we've got two quantities with measurements as 'a' and 'b' Then, their ratio(ratio of a to b) a:b

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

A.) 22/33 and 14/21

Here. the two ratios represent quantities that are proportional to 1/3.

B.) 48/60 and 35/42

Here. the two ratios represent quantities that are not proportional.

C.) 25/28 and 5/7

Here. the two ratios represent quantities that are not proportional.

D.) 16/13 and 13/16

Here. the two ratios represent quantities that are not proportional.

Hence, The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

Step-by-step explanation:

Rate of growing of weed mile-a-minute = 2 ft per day

To find:

Rate of growth of weed in inches per hour ?

Solution:

First of all, let us have a look at the following units conversion:

1 ft contains 12 inches

and 1 day is equal to 24 hours.

Rate of growth of weed is Length divided by number of days.

2 ft per day means Length of 2ft divided by 1 day.

i.e.

[tex]\dfrac{2\ ft}{1\ day}[/tex]

Let us put the units for conversion as discussed above:

[tex]\dfrac{2\times 12\ inches}{24\ hours}\\\Rightarrow \dfrac{24\ inch}{24\ hours}\\\Rightarrow \bold{1\ inches/hr}[/tex]

So, the answer is: 1 inch/hour
