HELP PLEASEEEEE!!!!!!

Explanation

Step 1

To solve the inequality means to find a range, or ranges, of values that an unknown g can take and still satisfy the inequality.

so

it means the solution is the set of values equal or smaller than 3.772,so

Part A:

Step 2

Part B:the graph of the inequality looks like a marked line in the number line, from3.772 to negative infinite, as the symbol is smaller or equal, the number3.772 is part of the set , so we use a filled circle

Step 3

in step 1 we used the addition property of inequality to isolate x, then in step 2 we draw the set solution .

The given function for the sales of [tex]S(t) = 7 - 6 \cdot \sqrt[3]{t} [/tex], gives the tax rate that maximizes government revenue as t = 343/512

The tax rate is the percentage of an amount that is paid to the government as tax.

The given function is presented as follows;

[tex]S(t) = 7 - 6 \cdot \sqrt[3]{t} [/tex]

Where;

t = The tax rate on imported shoes

S = The total sales

Taking the total sales as contributing to the government revenue, R(t), we have;

Revenue = R(t)

Which gives;

[tex]R(t) = t \times (7 - 6 \cdot {t}^{ \frac{1}{3} }) [/tex]

At the maximum total sales, we have;

[tex] \frac{dR(t)}{dt} = \frac{d t \times\left(7 - 6 \cdot {t}^{ \frac{1}{3} } \right) }{dt} = 0 [/tex]

[tex]\frac{d t \times\left(7 - 6 \cdot {t}^{ \frac{1}{3} } \right) }{dt} = 7- 8 \cdot \sqrt[3]{t} = 0[/tex]

Which gives;

At maximum revenue, t = (7/8)³

t ≈ 0.669921875

ANSWER

T = 4x + 25;

T = $37

EXPLANATION

Let the number of special exhibits to be visited be x.

The cost of the musuem entrance ticket is $25 and each special exhibit costs an additional $4.

This means that the cost of cisiting x additional exhibits is:

4 * x = $4x

Therefore, the total cost to enter the musuem and visit any number of special exhibits is:

T = 4x + 25

That is the expression that represents the total cost.

If a person wants to visit three exhibits, it means that:

x = 3

Therefore, the total cost, T, is:

T = 4(3) + 25

T = 12 + 25

T = $37

That is the total cost to enter and visit three exhibits.

When having an ordered pair, we say they are in direct variation if the quotient:

is constant. For case 1 we have:

we can solve for "x" by multiplying by "x" on both sides:

Now we multiply by 32/80 on both sides:

Solving the operations we get:

For case 2 we have:

Now we solve for "y" by multiplying by 20 on both sides:

Solving the operations:

The graph given is a linear graph,

so that means that the cost of cheese is linearly related to the weight of cheese bought.

The increase in the cost of cheese increase for each ounce Milan buys is, therefore, the slope of the graph;

to find the slope of the graph, we use any two points on the line; i'll be using (4,96) and (2,48)

This means that the cost of cheese increases by 24 cents for each ounce Milan buys.

Answer:

y = 6

Step-by-step explanation:

y= [tex]\frac{1}{x}[/tex]

3 = [tex]\frac{1}{4}[/tex]k  Solve for k by multiplying both sides by 4

12 = k

y = [tex]\frac{1}{2}[/tex](12)

y = [tex]\frac{12}{2}[/tex]

y= 6

We have the number:

If a number is added to the numerator and twice as much is added to the denominator and the result is 3/5, we can create the following equation:

Solve for x, using cross multiplication:

Answer:

Explanation:

a) To draw the 1st , 5th and 6th figures, we need to know the count of squares

For the first figure, we would have 3 squares

The fifth figure would have 35 squares

The sixth figure will have 48 squares

The way to get this is to add 2 to the odd number difference between the last two terms

b) Here, we want to know how the pattern is changing

From the information provided, the first pattern has 8 squares, the second has

15 squares while the last has 24 squares

We can have a formula as follows:

Given the function :

Given:

The length of each ribbon is 25 cm.

The number of ribbon need by mother is 6.

Explanation:

Determine the length of ribbon for daughter's hair.

Since length is in decimal so we need to find multiple of 25 such that it is more than 150 and multiple of 100.

The multiples of 25 are 25,50, 75, 100, 125, 150, 175, 200, ...

Since 200 is more than 150 and multiple of 100 also.

Determine the length of 200 cm in terms of meters.

So mother needs to buy 2 meters of ribbon.

Answer: 2 meters

Teh ratio of boys to girls in JAnice's classroom is 3:5

Total number of students 32

Let the ratio constant is K

So,

The equation will be

8K=32

K=32/8

K=4

So,

the boys will be

4 + 4 + 4 =3K =12

The number of girls will be :

She made an initial deposit that we will call "D", as it is one of the unknowns.

We know that she made a weekly deposit (lets call this amount "w").

After 4 weeks she had $450 in the account balance and this is the sum of the initial deposit and 4 weekly deposits, so we can write:

At the ninth week she had $825, that correspond to the initial deposit and 9 weekly deposits. This can be written as:

We have a system of linear equations that we will solve by elimination: we will substract the first equation from the second and then find w.

Now that we know "w", we can calculate D with any of the two equations:

Answer: the initial deposit was $150.

Answer:

If my theory is right the next 3 numbers are 21,28,36

Step-by-step explanation:

Looking at the beginning you see that 3 goes to 6 which is a hop of 3

Then next is 6 to 10 which is a hop of 4

Then next is 10 to 15 which is a hop of 5

So I think it’s going in a chronological number order

So I say the next hops will be 6,7,8

The probability of getting a red 7 would be; 1/26

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

Given that the total number of cards is 52.

WE are asked to find the he probability of getting a red 7

Since there are 2 red 7 cards in the deck of cards.

So, the number of favourable outcomes would be 2.

n (E) = 2

The probability

P(E) = n (E) /n (S)

Therefore, the probability of getting a red 7 will be;

P(E) = n (E) /n (S)

P(E) = 2/52

P(E) = 1/26

Hence, The probability of getting a red 7 would be; 1/26

So, we are writing a function. c(x) is the manufacturing costs, and x is the amount of bikes manufactured. The y-intercept is 1908 because when no bikes are manufactured it still costs 1908 to run the factory. The slope is 75 because it costs $75 to create a bike. So, y = mx + b, where m is the slope and b is the y-intercept is:

c(x) = 75x + 1908

Let the length of the rectangle be L.

Let the width of the rectangle be w.

The length of the rectangle is 3 more than twice the width.

This means that:

L = 3 + (2 * w)

L = 2w + 3

The perimeter of a rectangle is given as:

P = 2w + 2L

The perimeter of the rectangle is 96 inches. This means that:

96 = 2L + 2w

Recall that: L = 2w + 3

=> 96 = 2(w) + 2(2w + 3)

=> 2(w) + 2(2w + 3) = 96
