What is the estimate value of 102.3 divided by 4.7

Answer:

linear functions have no exponents higher than 1

Step-by-step explanation:

Answer:

20x+40

Step-by-step explanation:

x is the no of bracelets/per day

constant expense for a day = 10$

rent charge for 4 days = 40$

expense for beads/hardware for 4 days = 5X*4= 20x

exp = 20x+40

Answer:

10

Step-by-step explanation:

Set up an inequality

4x + 7.50 [tex]\leq[/tex] 50

4x  [tex]\leq[/tex] 42.50

x  [tex]\leq[/tex]  10.625

So the answer is 10 because you can't buy .625 of a book

Answer:

10 books

Step-by-step explanation:

50-7.50=42.5

42.5÷4=10.625

but that means it is only 10 books as there is no 10 and a half book

Answer:

Think of combining like terms when subtracting polynomials. For example, 3x² and -2x². They both have x² in common. So, if you were to combine 3x² and -2x², it would be like 3x² + (-2x²). Think of this like 3 + (-2), which equals 1. In this case, it would equal 1x² or x².

Let's take this problem for example: 6x² - 3x + 4 - (-2x² +2x - 2)

Parentheses are super important; The first thing you want to do is distribute the negative sign out to everything inside the parentheses!

So,

6x² - 3x + 4 - (-2x² +2x - 2) *multiply the neg. to -2x², 2x, and -2

Now, if you do that, the equation would now look like:

6x² - 3x + 4 + 2x² - 2x + 2

Now think of combining like terms. Here are the like terms:

6x² - 3x + 4 + 2x² - 2x + 2 (Let's rewrite it to look like this...)

6x² + 2x² - 3x - 2x + 4 + 2

Let's combine the x²'s first, so... 6x² + 2x² = 8x²

Let's combine the x's, so... -3x - 2x = -5x

Let's combine the constants (numbers with no variable), so... 4 + 2 = 6

Your solution should be 8x² - 5x + 6

ok so if we made a venn diagram it would look like this

math     neither      science

the ration math to science liking kids is

10:15 or 2:3

Hope This Helps!!!

The ratio of the students who like Maths to the students who like Science is 5:6.

A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.

(i) Given that, n(U)=50, n(S)=15, n(M)=10 and n(S∪M)=10

Let us take the students who like both subjects n(S∩M)=x

Now, 50=10+x+15+10

50=x+35

x=15

(ii) The number of students who like maths

=n(M)+n(S∩M)

= 10+15=25

The number of students who like Science

= n(S)+n(S∩M)

= 15+15=30

So, ratio is 25:30

= 5:6

Therefore, the ratio of the students who like Maths to the students who like Science is 5:6.

Substitute and solve for x:

Find y:

The expressions for each area are:  28x²-35x ( rectangle ), 9x² ( square ) and 37x²-35x ( total area )

This exercise requires your knowledge about the area of compound shapes. For solving this, you should:

The figure is composed of a square and a rectangle. See the attached image.

Therefore, you should sum the area of these geometric figures for determining the area of the irregular figure.

Area of the rectangle = bh . The figure shows that the sides for this rectangle are equal to 4x-5 and (4x+3x). Then,

b= length of the base= 4x-5

h=height=4x+3x=7x

Thus,  A_rectangle=bh= (4x-5)*7x=28x²-35x

Area of the square= l². The figure shows that the sides for this square are equal to 3x

    l= length of the side= 3x

Thus,  A_square=l²= (3x)² =9x²

A_total= A_rectangle+A_square

A_total= 28x²-35x+9x²

A_total= 37x²-35x

Answer:

7/32

Step-by-step explanation:

The reciprocal of a value is simply the inverse of it. That is, if a value n is any value in the number spectrum, the reciprocal would be 1/n.

In this case, 4 4/7 can be written as 32/7 as an improper fraction. Now the reciprocal of that would be to flip the numerators and the denominators. (1 / 32/7 is basically 1 * 7/32).

The reciprocal of 4 4/7 is 7/32.

Answer:

First of all, let us have a look at the formula for Total Surface Area of triangular prism:

TSA = B + p\times hTSA=B+p×h

Where B is the area of base

p is the perimeter of base and

h is the height of prism.

here base is a right angled triangle (because 3, 4, 5 is a triplet) Base and Height will be 3 , 4 cm or 4, 3 cm and 5 will be hypotenuse.

So formula for B:

\begin{gathered}B = \dfrac{1}{2}\times Base \times Height\\B = \dfrac{1}{2}\times 3\times 4 = 6 cm^2\end{gathered}

B=

Answer:

3$

Step-by-step explanation:

If the chicken was 4 times the amount of potatoes you would have to divide 12 by 4 to get you answer which would be 3$

12/4 = 3

potato's = 3$

to check you answer you would do 3 times 4 and if it gives you the cost of chicken (12) then it is correct.

Answer: $3

Step-by-step explanation:

If the chicken is 4 times as much, you can divide the cost of the chicken, which is $12. So, 12 divided by 4 is 3. The potatoes cost 3 dollars.

Answer:

x = 36

Step-by-step explanation:

Rearrange the equations before solving simultaneously

4y = -5x - 28

2y = 7x - 24

now subtract

4y - 2y = 2y

5x - 7x = -2x

-28 - - 24 = -4

put these values together.

2y - 2x - 4.

2y = 2x + 4

y = 2x + 4 / 2

y = x + 2

substitute this into one of the 1st equations in the question.

5x = -4(x + 2) + 28

5x = -4x + 8 + 28

5x = -4x + 36

9x = 36

x = 4.

The rule that maps figure 1 onto figure 2 is B. (x,y)→(x-5, y+11)

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable).

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, therefore,

Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Right shift by c units:

y=f(x-c)(same output, but c units late)

The correct option is B.

Rearrange the equation as

cos(x) - √(1 - 3 cos²x) = 0

cos(x) = √(1 - 3 cos²x)

Note that both sides have to be positive, since the square root function is non-negative. If we end up with any solutions that make cos(x) < 0, we must throw them out.

Take the square of both sides.

(cos(x))² = (√(1 - 3 cos²(x))²

cos²(x) = 1 - 3 cos²(x)

4 cos²(x) = 1

cos²(x) = 1/4

cos(x) = ± √(1/4)

cos(x) = ± 1/2

We throw out the negative case and we're left with

cos(x) = 1/2

This has general solution

x = arccos(1/2) + 360° n   or   x = -arccos(1/2) + 360° n

(where n is any integer)

x = 60° + 360° n   or   x = -60° + 360° n

Now just pick out the solutions that fall in the interval 0° ≤ x < 360°.

• From the first solution set, we have x = 60° when n = 0.

• From the second set, we have x = 300° when n = 1.

So the answer is D.

Answer:

  C.  {-1, 5, 8}

Step-by-step explanation:

Use each of the domain values in the function to see what the corresponding range value is.

  f(-1) = 5 -3(-1) = 8

  f(0) = 5 -3(0) = 5

  f(2) = 5 -3(2) = -1

The range is the set of numbers {-1, 5, 8}.

_____

Additional comment

The values in a set are generally listed lowest to highest. The coefficient of x in the equation for f(x) is negative, meaning the lowest range value will correspond to the highest domain value. If you start by finding f(2) = -1, you immediately eliminate all answer choices except B and C.

Those choices differ only in the middle value, so you can tell which is correct by evaluating f(x) for the middle domain value: f(0) = 5. Only one answer choice has both -1 and 5 in the set.

(There are two answers here: how you work the problem, and how you game a multiple choice question.)

Answer:

C. 46°

Step-by-step explanation:

The supplement of an angle is the other angle that makes the two angles add up to 180°. In other words, supplementary angles are angles that add up to 180°.

To find the measure of its supplement, we subtract 134 from 180, and then we get the angle measure.

Therefore, the answer is C. 46°.
