Answer:

[tex]6+2.5r\leq 50[/tex]

Step-by-step explanation:

Hi!

The options regarding the inequalities are not listed, though we can still proceed to write the inequality.

From the problem statement you cannot spend more than $50

and you are charged admission fee of $6 flat

a ride cost $2.50 per ride

the number of rides is given as r

yet in all you must not go beyond your limit

Therefore the inequalities can be presented as

[tex]6+2.5r\leq 50[/tex]

Answer:

2.5r + 6 ≤ 50

Step-by-step explanation:

Answer:

The answer is n = 31

Step-by-step explanation:

Equation:   2n + 13 = 75

2n = 75 - 13

2n = 62

n = 62/2

n = 31

check:

2*31 + 13 = 75

62 + 13 = 75

Answer: n = 31

Step-by-step explanation: Remember that the word sum mean addition.

So the sum of twice a number and 13 means 2n + 13 = 75.

So our equation is 2n + 13 = 75.

Now let's solve the equation.

Start by subtracting 13 from both sides to get 2n = 62.

Now, divide both sides by 2 and we have n = 31.

Answer:

(14, 6 )

Step-by-step explanation:

Given

[tex]\frac{1}{7}[/tex] x + [tex]\frac{1}{6}[/tex] y = 3 ( multiply through by 42 to clear the fractions )

6x + 7y = 126 → (1)

[tex]\frac{1}{2}[/tex] x - [tex]\frac{1}{3}[/tex] y = 5 ( multiply through by 6 to clear the fractions )

3x - 2y = 30 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 6x + 4y = - 60 → (3)

Add (1) and (3)term by term to eliminate x

11y = 66 ( divide both sides by 11 )

y = 6

Substitute y = 6 into either of the 2 equations and evaluate for x

Substituting into (1)

6x + 7(6) = 126

6x + 42 = 126 ( subtract 42 from both sides )

6x = 84 ( divide both sides by 6 )

x = 14

Solution is (14, 6 )

no just do the stuff in the parentheses then multiply by 5

Answer:

The cosine of angle C is 5/13, or approximately 0.38.

Step-by-step explanation:

To solve this problem, we must remember what the cosine of an angle represents.  The cosine of an angle is equal to the ratio of the adjacent side divided by the hypotenuse.

From the diagram, we can determine that the adjacent side length is 10 and the hypotenuse is 26.

Therefore, the cosine of angle C is:

10/26 = 5/13 (simplified)

Hope this helps!

Answer:

$35.2

Step-by-step explanation:

I’m assuming you meant the total of the dress after tax.

1. 32 * 1.1 = 35.2

OR

1. 32 * 0.1 = 3.2

2. 32 + 3.2 = 35.2

You could do it either way.

Answer:

7 is not a solution for x.

Step-by-step explanation:

To see if 7 is a solution for x, we will simply plug in the value for x and see if the left hand side is equal to the right hand side.

3x + 8 - x = 57 - 4

3(7) + 8 - (7) ?= 57 - 4

21 + 8 - 7 ?= 53

29 - 7 ?= 53

22 ?= 53  (( NO ))

Since 22 does not equal 53, 7 is not a solution for x.

Let's find the solution for x:

3x + 8 - x = 57 - 4

2x + 8 = 53

2x = 45

x = 22.5

Let's validate this solution for x:

3x + 8 - (x) = 57 - 4

3(22.5) + 8 - (22.5) ?= 57 - 4

67.5 + 8 - 22.5 ?= 53

45 + 8 ?= 53

53 == 53  (( YES ))

Since 53 is indeed equal to 53, then 22.5 is a solution for x.

Cheers.

Answer:

No, 7 is not a solution. x=11.25

Step-by-step explanation:

To find whether 7 is a solution, we can plug it in as x.

3(7)+8-7=57-4

21+15=53

36=53

No, 7 is not a solution.

We can find the solution by solving out the equation normally

3x+8+x=57-4

2x+8=53

2x=45

x=22.25

Answer:

k =  z/4 + 3

Step-by-step explanation:

8k-2z = 24

8k = 24 + 2z

k = (24 + 2z)/8

k = (24 + 2z) / (4*2)

k = (12 + z) / 4

k = 3 + z/4

Answer:

Rate of change = 18/√74

Step-by-step explanation:

The rate of change of f at x_o in the direction of the unit vector v is given by: ∇f(x_o) × v

Now, for us to get the direction of the unit vector, since we are told that f(x, y, z) = xyz in the direction normal to the surface yx² + xy² + yz² = 3, we will use; g(x, y, z) = yx² + xy² + yz² = 3 and k =3 to give;

∇g(x,y,z) = (2xy + y², (x² + 2xy + z²), 2yz)

So;

∇g(1, 1, 2) = (2(1 × 1) + 1²) , (1² + 2(1 × 1) + 2²), 2(1 × 2))

This gives;

∇g(1, 1, 2) = (3, 7, 4)

Now,

||∇g(1, 1, 2)|| = √(3² + 7² + 4²)

||∇g(1, 1, 2)|| = √74

Normal vector would be given by the formula;

v = [∇g(1, 1, 2)]/[||∇g(1, 1, 2)||]

Thus;

v = (3, 7, 4)/√74

Let's not forget that our ∇f(1, 1, 2) = (1, 1, 2)

Thus, rate of change is given by;

∇f(1, 1, 2) × v = (1, 1, 2) × (3, 7, 4)/√74

This gives;

Rate of change = [(1 × 3) + (1 × 7) + (2 × 4)]/√74 = 18/√74

Answer:

16x^2 - 8x - 3

Step-by-step explanation:

f(x) = 4x + 1

g(x) = 4x -3

f(x) * g(x) = (4x+1) * (4x-3)

(16x^2 - 12x + 4x -3)

Combine like terms

16x^2 - 8x - 3

that's your answer

The value of f (x) × g (x) will be;

⇒ 16x² - 8x - 3

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The value of function are,

⇒ f(x) = 4x + 1

⇒ g (x) = 4x - 3

Now.

Since, The value of function are,

⇒ f(x) = 4x + 1

⇒ g (x) = 4x - 3

Hence, We get;

⇒ f (x) × g (x) = (4x + 1) (4x - 3)

                    = 16x² - 12x + 4x - 3

                    = 16x² - 8x - 3

Thus, The value of f (x) × g (x)  = (16x² - 8x - 3)

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

y = 4/3x - 5

Comparing with the general equation above

Slope/ m = 4/3

Since the lines are parallel their slope are also the same

So we have

Slope of parallel line = 4/3

Answer:

B) Approximately 50%

Step-by-step explanation:

In any distribution of data, the data can be divided into 4 main quarters that are approximately equal in percentage.

Thus, the first quartile consists of approximately 25%, the second is 25%, third quartile about 25%, while the fourth is 25% also.

Therefore, in a data set distribution of students, approximately 50% of the distribution of students will fall within the first and third quartiles.

Answer:

(B) Approximately 50%

Step-by-step explanation:

First quartile is 1/4 and that is 25% of students in the distribution.

Third quartile is 3/4 and that is 75% of students in the distribution.

Between the first quartile and third quartile is automatically, 50% of the students in the distribution. The answer is (B) Approximately 50%.

Answer:

a) her estimate is wrong, because 22 crates can only contain 704 boxes

b) 23 crates

Step-by-step explanation:

Each crate can hold 32 boxes and there are total of 712 boxes.

Megan thinks she can fit all 712 boxes into 22 crates.

Now multiplying 22 crates 32 boxes to know the number of boxes22 crates can contain

= 22*32

= 704 boxes

The boxes are not all contacts in 22 crates

To pack 712 boxes

She Will need = 712/32 crates

She will need= 22.25 crates

Rounding up to whole number she will need 23 crates

Hello, first of all we could say, let 's replace x by 1 and see if we can conclude.

numerator gives [tex]\sqrt{1+15}-4=\sqrt{16}-4=4-4=0[/tex]

denominator gives 1-1=0

We need to ask a friend for help. Guillaume de l'Hôpital, French mathematician from the 1600s,  has a trick to solve this kind of stuff.

In short, he says that

[tex]\displaystyle \lim_{x\rightarrow c} \ {\dfrac{f(x)}{g(x)}}=\lim_{x\rightarrow c} \ {\dfrac{f'(x)}{g'(x)}}[/tex]

In our case here, we have c = 1

[tex]f(x)=\sqrt{x^2+15}-4\\\\g(x)=x-1[/tex]

[tex]f'(x)=\dfrac{1}{2}\dfrac{2x}{\sqrt{x^2+15}}=\dfrac{x}{\sqrt{x^2+15}}\\\\f'(1)=\dfrac{1}{4}\\\\g'(x)=1\\\\\dfrac{f'(1)}{g'(1)}=\dfrac{1}{4}[/tex]

Answer:

x= 20

Step-by-step explanation:

The two smaller angles add to 90 degrees

x + 3x +10 = 90

4x+10 = 90

Subtract 10 from each side

4x+10-10 = 90-10

4x = 80

Divide each side by 4

4x/4 = 80/4

x = 20

Answer:

[tex]x=20\textdegree[/tex]

Step-by-step explanation:

The angle we have here is a right angle. Right angles have a total measure of 90°. Therefore, the two parts must equal 90°:

Thus, we have the equation:

[tex](x)+(3x+10)=90[/tex]

Combine like terms:

[tex]4x+10=90[/tex]

Subtract 10 from both sides. The left side cancels:

[tex](4x+10)-10=90-10\\4x=80[/tex]

Divide both sides by 4. The left side cancels:

[tex](4x)/4=(80)/4\\x=20[/tex]

Thus, x is 20°.
