Answer: There are 10.46 pounds of apples left

Step-by-step explanation:

16.3 - 5.84 = 10.46

Answer:

625=63 to the nearest whole number

Step-by-step explanation:

= 4/100×25%

= 625

= 63 to the nearest whole number

Answer:

16

Explanation:

Reasoning:

You know that 4 students = 25% of the class,

and that ? students = 100% of the class,

So you would want to plan it out like this:

4 ----- 25%

? ----- 100%

This is how you would solve it:

            4 x 100

               25

Multiply 100 x 4 = 400

Divide  400/ 25 = 16

Answer:

321.

Step-by-step explanation:

First, divide 2250 by 7 to see how many times 7 can go in. You should get 321 and 3 as your remainder. To put it into mixed number format, it would put 321 as your whole number and your remainder divided by 7. It would be 321 3/7. Hope this helps :)

Answer:

A regular pentagon

Step-by-step explanation:

A pentagon has 5 sides. There are 5 tick marks.

The answer polygon is a Hexagon.

A hexagon is a six-sided polygon. Hexagon has some special properties when we are talking about inscribed polygons.

Two vertices of the hexagon lie on the corners of the diameter of the circumscribing circle.

Given that, Stella is using her compass and straightedge to complete the construction of a polygon inscribed in a circle.

We are asked which polygon is she in the process of constructing.

Since, there are 6 marks on the circle, which is one of the step for constructing a hexagon.

So, We can say that she is constructing a regular hexagon inside the circle.

An equation is a way of writing a statement with two or more expressions with operations such as addition, subtraction, multiplication, and division.

The value of the expression 17 − {2 + 2 [−1 (7 − 10) ] 2} is 3.

An equation is a way of writing a statement with two or more expressions with operations such as addition, subtraction, multiplication, and division.

Example: 2x + 3 x 4 - 3 is an expression.

We have,

= 17 − {2 + 2 [−1 (7 − 10) ] 2}

We will first solve,

(7 - 10) = 7 - 10 = -3

Now,

= 17 - {2 + 2[-1 x -3] 2}

We will solve [-1 x -3],

[-1 x -3] = 3

Now,

= 17 - {2 + 2 x 3 x 2 }
We will solve { 2 + 2 x 3 x 2 }

{ 2 + 2 x 3 x 2 } = 2 + 12 = 14

Now,

= 17 - 14

Subtracting we get,

= 3

Thus,

The value of the expression 17 − {2 + 2 [−1 (7 − 10) ] 2} is 3.

A) The rational equation that represents the given situation in the question is; (21 + x) = 0.9(25 + x)

B) Solving the equation gives the number of points needed to bring his average to 90% as; 15 points

We are told that he earned a total of 21 out of 25 possible points.

A) Now, if he has a perfect score on the next several quizzes, it means the number of points which we will call x that he needs to bring his average up to 90% is calculated from the rational equation;

(21 + x)/(25 + x) = 90%

⇒ (21 + x)/(25 + x) = 0.9

⇒ (21 + x) = 0.9(25 + x)

B) To find the number of points, let us solve the equation in A above to get;

(21 + x) = 0.9(25 + x)

Using distributive property on the right hand side, we have;

21 + x = 0.9(25) + 0.9x

21 + x = 22.5 + 0.9x

Using subtraction property of equality;

x - 0.9x = 22.5 - 21

0.1x = 1.5

x = 1.5/0.1

x = 15 points

Answer:

x [tex]\leq[/tex] - 3/2 (The graph is the image I attached)

Explanation:

1) Determine the sign of the fraction next to the variable, in this case, it's positive, which turns the equation into : x + 2/3 [tex]\leq[/tex] - 5/6

2) Move the constant to the right so that x is only on one side, this then turns the equation into: x [tex]\leq[/tex] - 5/6 - 2/3

3) Subtract the fractions, and the answer is x [tex]\leq[/tex]  -3/2

I don't know if you need to round the answer or not

Step-by-step explanation:

Hello there!

[tex]\sf \longmapsto 1.12 \: \times ( - 2.9)[/tex]

This is a arithmetic expression.We need to find the result of it.

[tex]\sf \longmapsto12.12 \times ( - 2.9)[/tex]

As (-) * (+) equals to (+),

The new Arithmetic expression will be :-

[tex]\sf \longmapsto - (12.12 \: \times 2 . 9)[/tex]

Then, Simply multiply :-

[tex]\sf \longmapsto - (35 .148)[/tex]

Remove the parenthesis:-

[tex]\sf \longmapsto - 35.148[/tex]

On Converting -35.148 to fraction :-

[tex]\sf \longmapsto \: - \dfrac{8787}{250} [/tex]

On Mixed fraction:-

[tex]\sf \longmapsto \: - 35\dfrac{37}{250} [/tex]

______________________________________

Henceforth the answer of the arithmetic expression is :-

[tex] \boxed{\bf \: - 35.148 \: (approx.)}[/tex]

In Alternate Form:-

Answer:

a) I am sorry, but I don't know this one.

b) y = mx + b

=> b = y-intercept = 0

=> m = slope = Rise/Run

=> Rise/Run = 120/65

=> Rise/Run = 24/13

=> Slope = 24/13

=> Our Equation: y = 24x/13

c) After drawing the trend line, we can conclude that if 100 costumers were served, the amount of tips would be about $185

d) To use a regression calculator, we must be given a table with x and y values. Then we insert the values in the calculator so that it can give us the whereabouts of a point and it can give us the trend line. After the trend line is given, we can make a prediction.

Hoped this helped. Sorry that I didn't answer the first part.

Answer:

Slope = ¼

Step-by-step explanation:

Given the following points from the graph, (0, 1) and (8, 3):

Let (x₁, y₁) = (0, 1)

     (x₂, y₂) = (8, 3)

Substitute these values into the following slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 1)/(8 - 0) = 2/8 = ¼

m = ¼

Therefore, the slope of the given graph is ¼.

Answer:

I think it this one but picture would help...

Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.  

Explanation:-

Given sets are A = { 1,20,30}

B = { 4,6}

Now,

A-B = { 1,20,30} -{ 4,6}

⇛ A-B = { }

Since there are no common elements in both A and B sets

⇛Number of elements in A-B = 0

⇛n(A-B) = 0

Therefore, n(A-B) = 0

Difference means subtraction and you subtract the smaller number from the bigger number. 5.38 - 3.15 = 2.23 in.

Answer:

2.23 inches

Step-by-step explanation:

We will subtract 3.15 from 5.38 because the problem is asking for the increase. We will take the new height and subtract the old height to see the difference.

c = 0

Step-by-step explanation:

There can only be one possibility to make this equation make sense. If we were to do any number greater than 0, the equation wouldn't work.

If c = 0

9(0) + 27 = 27

0 + 27 = 27

27 = 27 :)

If c = 1

9(1) + 27 = 27

9 + 27 = 27

36 ≠ 27 :(
