Answer:

Step-by-step explanation:

Yes it is because it can be written in the form y=kx.(y=5/9x)

The constant variation would be 5/9.

Pretty sure this is correct but if not, sorry! Hope this helps.

Answer:

This is a direct variation where the constant of variation is 5/9

Step-by-step explanation:

The equation for direct variation is y = kx

5x-9y =0

Lets try to get this equation in the above form

Add 9y to each side

5x-9y +9y = 9y

5x = 9y

Divide each side by 9

5/9 x = 9y/9

5/9x = y

This is in the form y = k x where k =5/9

Step-by-step explanation:

The surface area of a box is the sum of the areas of all the rectangular faces of the box.

Let length = x

Let width = y

Let height = h

SA = 2xy + 2xh + 2yh

Plug in the given values into the formula to find the area.

SA = 2(32)(25) + 2(32)(20) + 2(25)(20)

Answer:

D. The plumber charges a flat rate of $75.

Step-by-step explanation:

The vertical intercept is the point where the data intersects the vertical axis.  The vertical axis will be the dependent variable, and the horizontal axis will be the independent variable.  

In this situation, the total cost depends on how many hours the plumber works; this means that the total cost is the dependent variable, going on the vertical axis, and the number of hours is the independent variable, going on the horizontal axis.

The vertical intercept, since it is on the vertical axis, will be where the horizontal axis is 0.  In this situation, this means the cost when the plumber has been there 0 hours; this is the flat-rate fee he charges, $75.

km + 5x = 6y

Subtract 5x from each side:

km = 6y - 5x

Divide both sides by k:

m = 6y - 5x / k

Answer:

Step-by-step explanation:

m=-5x/k+6y/k

Answer:

For the $30 2 shirts and 2 hats each one would be $7.50.

For the $65 3 shirts and 8 hats each one would be $5.90

Step-by-step explanation:

Answer:

A shirt x cost $11

and a hat y cost $4

Step-by-step explanation:

Step one

This is a word problem and we can tackle it by expressing it Mathematically

Let us initialize shirt as "x" and hat as "y"

Now

1. 3 shirts and 8 hats cost $65

Mathematically

3x+8y= 65 - - - - - - - 1

2. the cost for 2 shirts and 2 hats is

$30

Mathematically

2x + 2y = 30---------2

We now have two equations with two unknowns

We can solve for the unknown simultaneously

Step a. Multiply equation one by 1

And equation two by 4

3x+8y= 65 - - - - - - - 1

8x + 8y = 120------------2

Step b

Subtracting equation one from two

3x+8y= 65 - - - - - - - 1

-(8x + 8y = 120) ------------2

=-5x+0=-55

-5x=-55

5x=55

x=55/5

x=11

Substituting the value of x in any of the equation above to solve for y say equation 2

2(11) + 2y = 30

22+2y=30

2y= 30-22

2y= 8

y= 8/2

y= 4

Hence a shirt x cost $11

And the hat y cost $4

Answer:

x = 0.1

The absolute values of 0.525 and -0.067 are 0.525 and 0.067, respectively. Therefore, |0.525| is greater than |-0.067|.

To compare the absolute values of 0.525 and
-0.067
, we need to understand what absolute value means. The absolute value of a number is the non-negative value of that number without regard to its sign. So, for both positive and negative numbers, the absolute value is always positive or zero.

The absolute value of any number is represented by two vertical lines on either side of the number, for instance, |0.525| and |-0.067|. When we calculate these:

Comparing the two absolute values, we see that 0.525 is greater than 0.067. Therefore, |0.525| > |-0.067|.

Answer:

27.52 percent

Step-by-step explanation:

Percentage increase = (new - original)/ original * 100

new = 318270

old = 249583

Substitute in what we know

percentage increase = (318270-249583)/249583 *100

                                     = (68687/249583) *100

                                       .275207045*100

Answer:

[tex]y =\displaystyle\frac{1}{4}x^{0.5}[/tex]

It is a power function.

Step-by-step explanation:

We are given the following function in the question:

[tex]y =\displaystyle\frac{1}{4}x^{0.5}[/tex]

We have to check whether the given function is a power function or not.

Power Functions :

[tex]f(x) = ax^p,[/tex]

where a is a constant and not equal to zero and p is a real number.

Comparing the given function, we get:

[tex]a = \displaystyle\frac{1}{4}\\\\p = 0.5[/tex]

Hence, the given function is a power function.

The equation y = 1/4x^0.5 is a power function because it fits the general form of a power function, y = ax^n, with a constant coefficient and a real number exponent.

Yes, the function y = 1/4x^0.5 is indeed a power function. A power function is of the form y = ax^n, where a is a constant and n is a real number, representing the power of x. In the given function, a is equal to 1/4, and n is 0.5, which is equivalent to the square root of x (since raising a number to the 0.5 power is the same as taking its square root).

Therefore, we can express the square root of x as x raised to the power of 1/2, fitting the form of a power function.

Answer:

$22.1

Step-by-step explanation:

To solve this, you must multiply the amount of the items by its cost.

This is the amount of yams in decimal form: [tex]4\frac{1}{2}[/tex] = 4.5

This is the amount of carrots in decimal form: [tex]4\frac{3}{10}[/tex] = 4.3

4.5 * 3 = 13.5

4.3 * 2 = 8.6

Now we add them together to get the total cost.

13.5 + 8.6 = 22.1

Answer:

$22.10

Step-by-step explanation:

This is simple multiplication.

1. It may help you to simplify the pound values. 4 and 1/2 is really 4.5, and 4 and 3/10 is really 4.3

2. We know what the cost is per pound, and we know how many pounds we have. We simply multiply.

4.5 pounds of yams * $3 per pound = 13.5

4.3 pounds of carrots * $2 per pound = 4.3*2 = 8.6

3. Add the values

13.5+8.6 = 22.1 = $22.10

Answer:

2496144

Step-by-step explanation:

Total number of members of the senate on the finance committee (n)= 24

Number of members in each subcommittee(r) = 13

We need to make use of the combinations formula

C(n,r) = [tex]\frac{n!}{r!(n-r)!}[/tex]

1) Plugging in the values of n and r into formula, we get

C(24,13) = [tex]\frac{24!}{13!(24-13)!}[/tex]

= [tex]\frac{24!}{13!*11!}[/tex]

= [tex]\frac{24*23*22*21*20*19*18*17*16*15*14*13!}{13!*11!}[/tex]

2) Cancelling out the 13! from the top and bottom, we get

= [tex]\frac{24*23*22*21*20*19*18*17*16*15*14}{11!}[/tex]

= [tex]\frac{24*23*22*21*20*19*18*17*16*15*14}{11*10*9*8*7*6*5*4*3*2*1}[/tex]

3) Upon simplifying the numbers on the top and bottom, we get

C(24,13) = 2496144

Answer:  The correct option is (B) 55°.

Step-by-step explanation:  We are given to find the measure of angle 1 in the trapezoid shown in the figure.

We know that

one pair of sides of a trapezoid are parallel to each other.

As shown in the figure, the base of the trapezoid and its opposite side are parallel to each other.

Also, they are cut by a tranversal such that the angle 1 and the angle with measure 125°  are interior angles on the same side of the transversal.

So, the sum of the measures must be equal to 180°.

That is,

[tex]125^\circ+m\angle 1=180^\circ\\\\\Rightarrow m\angle 1=180^\circ-125^\circ\\\\\Rightarrow m\angle 1=55^\circ.[/tex]

Thus, the required measure of angle 1 is 55°.

Option (B) is CORRECT.

Answer:

see explanation

Step-by-step explanation:

To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term.

product = 2 × - 6 = - 12 and sum = + 11

The factors are + 12 and - 1

Use these factors to split the middle term

2x² + 12x - x - 6 = 0 ( factor the first/second and third/fourth terms )

2x(x + 6) - 1(x + 6) = 0 (factor out (x + 6) )

(x + 6)(2x - 1) = 0

equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

2x - 1 = 0 ⇒ x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We can use ratio's to solve this problem

1 inch           4 inch

------------ = --------------

30 yds         x yds

Using cross products

1 * x = 30*4

x = 120

So we know 4 inches  is 120 yds

Answer:

x=6.33

Step-by-step explanation:

4=3x-15

19=3x

6.33=x

f(4) This means that x is 4, so you can plug in 4 for "x" in the equation

f(x) = 3x - 15

f(4) = 3(4) - 15

f(4) = 12 - 15

f(4) = -3

x = 4  1/3 buckets of fish left to eat

Answer: C . sin55/8 = sin30/b

Answer:

C. [tex]\frac{\text{Sin 55}^{\circ}}{8}=\frac{\text{Sin 30}^{\circ}}{b}[/tex]

Step-by-step explanation:

We have been given that in triangle ABC, mA 55, mB-30, and a 8. We are asked to find the equation that we can use to solve the length of side b.

We will use law of sines to solve our given problem.

[tex]\frac{\text{Sin A}}{a}=\frac{\text{Sin B}}{b}=\frac{\text{Sin C}}{c}[/tex], where A, B and C represents angle of a triangle corresponding to sides a, b and c respectively.

Upon substituting our given values in law of sines we will get,

[tex]\frac{\text{Sin 55}^{\circ}}{8}=\frac{\text{Sin 30}^{\circ}}{b}[/tex]

Therefore, the option C is the correct choice.

Answer:

(- 2, - 1)

Step-by-step explanation:

To determine which ordered pair is a solution of the inequality, substitute the x-coordinate into the left side and compare validity with the y-coordinate

(- 2, - 1)

- 6 + 5 = - 1 = - 1 → (- 2, - 1) is a solution

(2, - 1)

6 + 5 = 11 > - 1 → (2, - 1) is not a solution

(3, - 5)

9 + 5 = 14 > - 5 → (3, - 5) is not a solution

(- 3, - 5)

- 9 + 5 = - 4 > - 5 → is not a solution

The only pair that makes the inequality true is (- 2, - 1 )
