Answer:

25 students are in mr. Watsons class.

Step-by-step explanation:

10/40=.25, so 25 students

Answer:

24 adults

Step-by-step explanation:

The equation to represent the scenario is

4x + 7x = 66

Combine like terms

11x = 66

Isolate x

x = 6

To find the amount of adults attending the carnival, substitute 6 with x.

6*4 = 24 adults

7*4 = 42 children

24 + 42 = 66 people in total

Hasan's Expression: d - 0.25d

--------------------

Bella's Expression: 0.75d

=============================================

Explanation:

The variable d stands for the original price. The store is offering a 25% sale, which means that Hasan will save 25% of the original price. This means 0.25d represents the amount he saves (aka the discount amount).

For instance, let's say d = 100 is the original price. 25% of this is 0.25d = 25 dollars. So if the book is originally $100, then he saves $25.

As you can probably guess, the 0.75 comes from 1 - 0.25 = 0.75; it indicates that if Hasan saves 25%, then he still has to pay the remaining 75%

Notice how d - 0.25d = 1d - 0.25d = (1-0.25)d = 0.75d which points to the sale price being 75% of the original price d.

Answer:

P = 12 + 5x

Step-by-step explanation:

P = a + b + c

P = 7 + (x + 4) + (4x + 1)

  = 7 + x + 4 + 4x + 1

  = 12 + 5x

Answer:

[tex]f(-3)=343[/tex]

Step-by-step explanation:

[tex]f(x)=(\frac{1}{7} )^x[/tex]

Plug -3 into x and solve using the negative power rule:

[tex]x^{-a}=\frac{1}{x^a}[/tex]

[tex]f(-3)=(\frac{1}{7} )^{-3} \\\\f(-3)=\frac{1}{\frac{1}{7}^3 } \\\\f(-3)=\frac{1}{\frac{1}{343} } \\\\f(-3)=343[/tex]

Answer:

I believe that it is $901.20

Step-by-step explanation:

I make this assumption Because when we withdraw, we take away. If Kayla wrote these for checks, you just simply add them up and you get a total of $901.20.

We aren’t sure how much she had before withdrawing this money

23 is the median of the data set

Answer:

$1000 per month

Step-by-step explanation:

5000 dollars is 100 percent so we put 5000 over 100

5000/100

then since we need to find 20 percent of something, we put x over 20

x/20

Then we cross multiply

5000      times       x              

100                        20

so 100x = 100000

and x = 1000

Step-by-step explanation:

The perimeter of the given triangular image will be 5x + 12.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

As per the given triangular triangle,

Perimeter = 7 + (x + 4) + (4x + 1)

Perimeter = 7 + 5x + 5

Perimeter = 5x + 12

Hence "The perimeter of the given triangular image will be 5x + 12".

Change to improper fractions

2 1/4 = (4*2+1)/4 = 9/4

3 1/5 = (5*3+1)/5 = 16/5

9/4 * 16/5

Rewriting

9/5 * 16/4

9/5 * 4/1

The magnitude of a vector a is the length of the vector.

We write it ||a||

We can draw a right triangle and apply the pythagoras theorem. The magnitude of a will be the hypotenuse :

||a||² = 3² + 3²

||a||² = 9 + 9

||a||² = 18

||a|| = √18 = √(9*2) = 3√2 ≈ 4.24

So the answeer is 4.24

Answer: 8 days.

Explanation;

11/2 = 5.5

5.5 x 3 = 16.5

132/16.5 = 8

Answer:

8 days

Step-by-step explanation:

So, 11/2 * 3 = (33/2) = 16.5 ml  

Let the number of days medicine last be 'x'.  

⇒ 16.5 * x = 132  

⇒ x = 132/16.5  

⇒ x = 8.  

Therefore, Medicines last for 8 days.

Answer:

The number of possible juries is C(30,12) = 30! / (30–12)! * 12! = 86,493,225. The number of possible all-female juries is C(16,12) = 16! / (16–12!) * 12! = 1820. So the probability of an all-female jury is 1820 / 86,493,225 = 0.0021%.

Explanation:

Put the given value of x into the expression and evaluate it.

x, 10(x +6), y = 10x +60

2, 10(2 +6), y = 10(8) = 80

4, 10(4 +6), y = 10(10) = 100

6, 10(6 +6), y = 10(12) = 120

8, 10(8 +6), y = 10(14) = 140
