........what’s the value of x?

Answer:

30 students

Step-by-step explanation: If 60% is 18, then 10% wold be 3. And we know that 10% multiplied by 10 is 100%. Therefore 3 multiplied by 10 should be euqal o the total amount of students. And since 10% times 3 is 30, there are 30 students in total.

Answer:

30 students

Step-by-step explanation:

We can do this question using direct proportion.

"If 18 girls represent 60%, how many students represent 100%?"

18/60=x100

x=18×100/60

30 students altogether.

Step-by-step explanation:

Answer: It will take him 38 weeks.

Step-by-step explanation:

We will model the situation by an equation.

Leon already knew 24 appetizer recipes so it will be permenant. He will learn to more each week so we can achieve the expression . 24 + 2x where x is the number of weeks.

If we want to know the number of weeks it will take him to learn 100 appetizer recipes then we will have to set the equation equal 100.

24 + 2x = 100   Now solve for x

-24         -24

2x = 76

x = 38

Answer:

Her new hourly wage will be $23.10.

Step-by-step explanation:

First, let's find out how much her raise is in dollars.

0.05 x 22 = 1.10

Then, let's add that to her current wage.

1.10 + 22.00 = $23. 10

The amount of money of her new hourly wage will be $23.1 per hour.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Sara's boss informed her she is getting a 5% raise. She currently makes $22 per hour.

Let 'y' be the new hourly wage. Then the equation is given as,

0.05 = (x - $22) / $22

x - $22 = $1.1

x = $23.1 per hour

The amount of money of her new hourly wage will be $23.1 per hour.

Hi!

Your answer would be: almost $5, but the actual amount is $4.67.

Reason being: when you divide $140 by 30, you get $4.67, and rounding to the nearest number, you get $5.

Therefore, the answer is $4.67

Answer:

A is graph 3

B is graph 1

C is graph 2

Step-by-step explanation:

A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.

B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.

C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.

(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)

"What is the general process for solving an equation with one variable?"...

Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.

Example:

2x+4=64

Add -4 to both sides to isolate the variable.

(2x+4)+(-4)=(64)+(-4)

Simplify.

2x=60

Divide both sides by 2 to isolate the variable on one side.    

(2x)/2=(60)/2

x=30

The answer is below

Step-by-step explanation:

Given that the minimum monthly requirements are 840 pounds of phosphoric​ acid, hence:

35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric​ acid

35x + 14y ≥ 840

The minimum monthly requirements are 540 pounds of nitrogen, hence:

15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen

15x + 18y ≥ 540

The minimum monthly requirements are 768 pounds of potash, hence:

16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash

16x + 64y ≥ 768

Also, x ≥ 0 and y ≥0.

Therefore the equations are:

35x + 14y ≥ 840

15x + 18y ≥ 540

16x + 64y ≥ 768

x ≥ 0 and y ≥ 0

Answer:

The total worth of the investment after 6 months is T =  $ 1004004

The geometric mean of the above monthly returns is   [tex]\= G = 0.001[/tex]

Step-by-step explanation:

From the question we are told that

  The growth for each month are

             R1 = -0.4, R2= 0.67, R3 = 1.0, R4 = -0.5, R5 = 0.2, R6 = -0.165

   The amount invested is  [tex]A = \$ 1,000,000[/tex]

   The number period of the investment is  6 months

Generally the worth of the investment after each month is

              [tex]G_i = G_p * (1 + R_i)[/tex]

Here [tex]G_p[/tex] is the worth of the investment the previous year

          [tex]R_i[/tex] is the growth for that month

So considering the first month

          [tex]G_1 = G_p (1 + R_1)[/tex]

Here [tex]G_p = A[/tex]

So

             [tex]G_1 = 1000000 (1 -0.4)[/tex]

              [tex]G_1 = 600000[/tex]

Considering the second month

  Here [tex]G_p = 600000[/tex]

So

    [tex]G_2 = 600000 (1 + 0.67)[/tex]

=>  [tex]G_2 = 1002000[/tex]

Considering the third month

    Here [tex]G_p = 1002000 [/tex]

So    

    [tex]G_3 = 1002000 (1 + 1)[/tex]

    [tex]G_3 = 2004000 [/tex]

Considering the fourth month

    Here [tex]G_p = 2004000 [/tex]

So  

    [tex]G_4= 2004000 (1 + -0.5)[/tex]

    [tex]G_4= 1002000 [/tex]

Considering the fifth  month

    Here [tex]G_p = 1002000 [/tex]

So  

    [tex]G_5= 1002000 (1 + 0.2)[/tex]

    [tex]G_5= 1202400 [/tex]

Considering the six month

       Here [tex]G_p = 1202400 [/tex]

So  

    [tex]G_6= 1202400 (1 -0.165)[/tex]

    [tex]G_6= 1004004 [/tex]

Generally the total  worth of the investment after 6 months is T =  $ 1004004

Generally the geometric mean of the monthly returns is  

           [tex]\= G = \sqrt[n]{ [(1 + R_1 ) * \cdots (1 + R_n)} ]-1[/tex]

Here  n represents the number of months which has a value  n =  6

So

  [tex]\= G = \sqrt[6]{[(1+ (-0.4 )) * (1 + 0.67) * \cdots * (1 + (-0.165))]} - 1[/tex]

    [tex]\= G = 0.001[/tex]

Step-by-step explanation:

as 9 isnt divisible by 15 or even, it cant be true. it cant be a prime number and even so thats not true either. the number must be 30 because it is divisible by 15 and even and the least possible value.

Answer:

The answer is D. 55%

40% cashews in 15 ounces = 40/100 × 15 = 600/100 = 6 ounces of cashew

60% cashew in 45 ounces = 60/100 × 45 = 2700/100 = 27 ounce of cashew

total weight of the mixed nuts = 15 + 45 = 60 ounces

total weight of cashew = 27 + 6 = 33 ounces

% of cashew in the 60 ounce bag = 33/60 × 100 = 3300/60 = 55%

Two lines with congruent alternate interior angles would be parallel.

The answer is true.
