Step-by-step explanation:

Answer:

1.1 percent

Step-by-step explanation:

[(9.73 - 9.84) / 9.84 ] * 100 = -1.1 percent change = 1.1 percent decrease

Answer:

x = 10

Step-by-step explanation:

Use Pythagorean Theorem

c2 = a2 + b2

Here you must find the hypotenuse length (x) which is c in the equation. Thus substitute the values given into the equation:

c2 = 6^2 + 8^2

c2 = 100

Square root both sides so

c = 10

Thus length of x is 10

Answer:

All you would do is times 12 by .15 or 15% you get 1.8 then all you do is 12 minus 1.8 you get $10.20 that is the price of a discounted pizza

Answer:

x= 4/3

x= -1/2

Step-by-step explanation:

2x (3x-4) +1(3x-4) = 0

Distribute

6x^-8x +1(3x -4) = 0

Multiply by 1

6x^2 -8x +3x-4=0

Answer:

(2x + 1) ( 3x - 4) = 0

solve by factoring

2x + 1 = 0

2x = -1

divided by 2 on both sides

x = -1/2

3x - 4 = 0

3x = 4

divided by 3 on both sides

x = 4/3

x¹ = -1/2 , x² = 4/3 is the solution

3 × 7Kg = 21 Kg

Answer:

[tex]x=\frac{3}{4}=0.75[/tex]

Step-by-step explanation:

From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.

In this case, we are given that two opposite sides have lengths of [tex]4x+5[/tex] and [tex]8[/tex]. Therefore, since the quantities must be equal, we can write the following equation to solve for [tex]x[/tex]: [tex]4x+5=8[/tex]. Solving for [tex]x[/tex], we get:

[tex]4x+5=8[/tex]

[tex]4x=3[/tex] (Use the Subtraction Property of Equality to subtract [tex]5[/tex] from both sides of the equation, which isolates [tex]x[/tex])

[tex]x=\frac{3}{4} =0.75[/tex] (Use the Division Property of Equality to divide both sides of the equation by [tex]4[/tex] to get rid of [tex]x[/tex]'s coefficient)

Answer:

  B.  51

Step-by-step explanation:

In statistics, "range" generally means the difference between the maximum and the minimum. To find the range of these numbers, locate the maximum (54) and the minimum (3) and find their difference:

  54 -3 = 51

The range of the numbers is 51.

_____

Additional comment

The range is used for a variety of purposes. In some cases, it can be used to estimate the variance. In other cases, it can be used to choose bin boundaries for a histogram or other chart of values.

This use of the term "range" should not be confused with the idea of the "range" of a function. That is the list (or description) of all function values.

Answer:

2x° = 45°, 3x° = 67.5°

Step-by-step explanation:

Sum of angles in a triangle = 180°

2x+3x+3x=180°

8x=180°

x=22.5°

2x=22.5°x2=45°

3x=22.5°x3=67.5°

Answer:

24 classes

Step-by-step explanation:

Let

x = number of classes

Devaughn is a member at the local gym = 120 + 5x

Jerome is not a member = 10x

Equate the total cost of both individuals

120 + 5x = 10x

120 = 10x - 5x

120 = 5x

x = 120/5

x = 24 classes

The total cost of Devaughn and the total cost of Jerome will be equal in 24 classes

Answer:

It will be 63.9

Step-by-step explanation:

Trust me, I got it right

Answer:

63.6mm² (the last option)

Explanation:

the formula for calculating the area of a circle is πr², where r is the length of the radius.

in this case, we know that 9mm is the length of the diameter of the circle, so we can divide that by 2 to get 4.5mm for the length of the radius.

the question has instructed us to use 3.14 for π (pi), so we can substitute these values into the formula:

πr² = 3.14 × 4.5² = 63.585mm²

we can now round this to the nearest tenth to get 63.6mm², which would be the last option.

Answer:

opposite sides of a parallelogram are equal

2x+15=x+15

2x-x=15-15

x=0

Answer:

x = 0

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, that is

ST = RU , substitute values

2x + 15 = x + 15 ( subtract x from both sides )

x + 15 = 15 ( subtract 15 from both sides )

x = 0

Answer:

Slope is -3

Equation is y = -3x + 2

Step-by-step explanation:

(0 , 2) and ( -1 , 5)

m= (y2-y1)/(x2-x1)

m= (5 - 2)/(-1 -0)

m= 3/-1

m= -3

y - y1 = m(x - x1)

y - 2 = -3(x - 0)

y - 2 = -3x + 0

y = -3x + 2

Answer:

-8

the way you meant to write it was -4^2 x 2^-1

Answer:

it is 8 but it's not negative 8

I tried negative 8 and it said it was wrong so it must be 8

Answer:

698 fishes

Step-by-step explanation:

Generally, we can represent an exponential growth function as;

y = a•(1 + r)^t

originally, there were 3 fishes

The original value in this case means a = 3

After 6 weeks, there were 31

31 in this case is y

r is the increase percentage or rate

t is the time

So, we have it that;

31 = 3•(1 + r)^6

31/3 = (1 + r)^6

10.33 = (1 + r)^6

ln 10.33 = 6 ln (1 + r)

ln 10.33/6 = ln (1 + r)

e^0.3892 = (1 + r)

1 + r = 1.476

r = 1.476-1

r = 0.476 or 47.6%

So the growth percentage or rate is 47.6%

For 14 weeks, we simply have the value of t as 14;

So ;

y = 3•(1 + 0.476)^14

y = 3(1.476)^14

y = 698 fishes

Answer:

E. 1d+0.015d

G. 1.015d

Step-by-step explanation:

A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.

Answer:

this should be right 103.075

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Yes, they will form a triangle. This is so because when testing for, we use the simple and logical analysis of

Adding up the two shorter sides > the third longest side.

In the example of the question we have here. The two short sides are 11 and 12 respectively. Adding them up together, we have

11 + 12 = 23

And the third longest side to be 17. Now, is 23 greater than 17 or not?

Of course it is, so yes, the sides will form a triangle.
