What is the perimeter of the regular heptagon below?

Answer:

C

Step-by-step explanation:

This is because 30d would be multiplying whatever the cost by 30, however with 0.3d you are taking 0.3 or 30% off of the whole number.

Answer:

B, H

Step-by-step explanation:

The electrician charges 45 dollars per hour and 30 at the beginning. We are multiplying the hours, h, by 45 to get 45h. We add 30 to get C=45h+30

Jerome will always earn 75 dollars, but he also gets 10 percent commission, which is 0.10.

Answer:

B and H are the correct answers

Answer:

x < -9

Step-by-step explanation:

Add 8 to both sides:

-3x - 8 > 19

-3x > 27

Divide each side by -3:

-3x > 27

Dividing by a negative number on each side switches the inequality:

x < -9

So, the answer is x < -9

Answer:

[tex] \huge \: x < - 9[/tex]

[tex]\huge \: x \in (-∞,-9)[/tex]

Step-by-step explanation:

the direction of inequality doesn't change when you

the direction of inequality does change when you

[tex]step - 1 : define \\ -3x-8>19[/tex]

[tex]step - 2 : \\ add \: 8 \: to \: both \: sides[/tex]

[tex]-3x-8 + 8>19 + 8[/tex]

[tex] - 3x >27 [/tex]

[tex]step - 3 \: \\ divide \: both \: sides \: by \: - 3 \: and \: swap \: the \: inequality[/tex]

[tex] \huge \therefore \: x < - 9[/tex]

Answer:

6

Step-by-step explanation:

18 divided by 3 equals 6.

Answer:

6

Step-by-step explanation:

18 ÷ y

18 ÷ 3 ^ Substitute 3 in for y, as y equals 3.

6 ^ Divide.

Given:

The equation is

[tex]8x-1=-50[/tex]

To find:

The value of x by separating the variable.

Solution:

We have,

[tex]8x-1=-50[/tex]

Here, -1 is not next to the variable. So, move -1 to the other side of the equation by using the opposite operation. After moving -1 to the right side of the equation it will become +1.

[tex]8x=-50+1[/tex]

[tex]8x=-49[/tex]

Divide both sides by 8.

[tex]x=\dfrac{-49}{8}[/tex]

Therefore, the value of x is [tex]\dfrac{-49}{8}[/tex].

Answer:

circle graph

Step-by-step explanation:

The function with range -4 ≤ y ≤ 3 and domain 0 ≤ x ≤ 3 represents a circle. The graph is shown below.

A graph is a diagram that depicts the relationship between two variables, usually measured along opposite axes in a pair, is used.

The range of the function is given below,
-4 ≤ y ≤ 3.

And the domain of the function is grater than or equal to 0 and less than or equal to 5.

Implies that,

0 ≤ x ≤ 3.

And  the value of y varies from -4 to 3, for the values of x.

So the graph of the function can be a circle,

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

Answer:

(x, y) = (2, 9)

Step-by-step explanation:

y = 9x - 9

y = 9

Substituting the value of y ( second equation) into the first eqaution, we get:

9 = 9x - 9

18 = 9x

x = 2.

Answer:

The price of each big peach is: $0.45

Step-by-step explanation:

Given that

Total peaches = 270

The ratio of small to medium to big peaches

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

Now

[tex]Small\ peaches = \frac{2}{9} * 270 = 60\\Medium\ peaches = \frac{4}{9}*270 = 120\\Big\ peaches = \frac{3}{9} *270 = 90[/tex]

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

[tex]Price\ of\ all\ medium\ peaches = Total\ cost-(Cost\ of\ small\ peaches+ Cost\ of\ medium\ peaches)\\= 91.50 - (15+36) \\=91.50-51\\=40.5[/tex]

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches

So,

[tex]Cost\ of\ one\ peach = \frac{40.5}{90} = 0.45[/tex]

Hence,

The price of each big peach is: $0.45

0.45 cent

Given that

Total peaches = 270

The ratio of small to medium to big peaches.

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches.

So the price of each big peach is: $0.45

Answer:

3z < -4.8

* be sure to use the less than or equal to sign

Step-by-step explanation:

The inequality for the A number z times 3 is at most -4.8 is 3x < -4.8

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

A number z times 3 is at most -4.8

Now, the mathematical expression is

3z < -4.8

and, z< -1.6

Hence, the inequality is 3x < -4.8
