An article bought for $125 was sold for $175.What percentage profit was? A.28.6 percent B. 40 percent C. 50 percent D. 71.4 percent guys please help me​

Answer:

29.96

Step-by-step explanation:

First find the discount

35 * 20 %

35*.2

7

Subtract the discount from the price

35-7

28

Now find the tax on the new price

28* 7%

28 *.07

1.96

Add the tax to the new price

28+1.96

29.96

Answer:

D(12) = 2,600 miles

It means a distance of 2,600 miles is already traveled from home after 12 hours

Step-by-step explanation:

To find D(12); all we have to do is to substitute the value of 12 for D

We have this as;

D(12) = 3260-55(12)

D(12) = 2,600

In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours

Answer:

volume of the prism=(1/2×(6+12)×4)×10

=36×10

=360 cm³

Answer:

d

Step-by-step explanation:

just took test

Answer:

d = 6

Step-by-step explanation:

Since the line is horizontal then the distance from B to C is the distance between the x- coordinates.

d = | - 3 - 3 | = | - 6 | = | 6 | = 6

Answer:

option C

Step-by-step explanation:

[tex]distance, d = \sqrt{(x_B- x_C)^2 + (y_B - y_C)^2}[/tex]

               [tex]=\sqrt{(-3 -3)^2 + (6 - 6)^2 }\\\\=\sqrt{(-6)^2 + 0 }\\\\=\sqrt{36}\\\\= 6[/tex]

[tex]B[/tex]

Step-by-step explanation:

Let's explore possible case scenarios.

---------------------

Case A) Each person gets a rose and a daisy (2 flowers per person)

In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.

---------------------

Case B) Each person gets a rose only (1 flower per person)

Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.

----------------------

Case C) Each person gets a daisy only (1 flower per person)

We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.

-----------------------

Case D) Each person gets 2 roses

Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.

-----------------------

Case E) Each person gets 2 daisies

Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.

------------------------

Case F) Each person gets 2 daisies and 1 rose

We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.

------------------------

In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.

Answer:

-30x-27y = -21

Step-by-step explanation:

We know that;

-30x-27y = 3(-10x-9y)

Recall, -10x-9y = -7

Thus; -30x-27y = 3(-7) = -21

Answer:

9.8x+1.1y+9.9z

Step-by-step explanation:

Hi there!

Perimeter = Sum of all sides

[tex]P=(5.5x + 6.2y)+(4.3x + 8.3z)+(1.6z - 5.1y)[/tex]

Open up the parentheses

[tex]P=5.5x+6.2y+4.3x+8.3z+1.6z-5.1y[/tex]

Combine like terms

[tex]P=5.5x+4.3x+6.2y-5.1y+8.3z+1.6z\\P=9.8x+1.1y+9.9z[/tex]

Therefore, the expression 9.8x+1.1y+9.9z (cm) best represents the perimeter of the triangle.

I hope this helps!

The required rounding of the number 8.31 ÷ 1.87 is 4.4.

Given that,

To find the simplified value for 8.31÷1.87.

A recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

Here,
8.31÷1.87 = 4.444
Where 4 is a repeating decimal so the round to 1 decimal point is 4.4

Thus, the required rounding of the number 8.31 ÷ 1.87 is 4.4.

Answer: 128 cubes

Step-by-step explanation:The dimension of the rectangular prism is not given, assumed not important.

Find the volume of 1 cube:

Volume = 1/4 x 1/4 x 1/4

Volume = 1/64 units³

Find the number of cubes that can go into the prism:

Number of cubes = 2 ÷ 1/64

Number of cubes = 128

Answer: exponential  function

Step-by-step explanation:

Graph it.

You will see that the ordered pairs make the shape of a sideways "S."

Linear functions are straight lines and quadratic functions are "U" or upside-down "U" shaped curves. Exponential functions can have multiple curves like including a sideways "S" shape, so it is exponential.

Answer:

[tex]637[/tex]

Step-by-step explanation:

Step 1: Set Up System of Equations

[tex]a + b = 13[/tex]

[tex]ab = 40[/tex]

Solve for a in the first equation

[tex]a = 13 - b[/tex]

Subsitur that in for the 2nd equation

[tex](1 3 - b)(b) = 40[/tex]

[tex] - b {}^{2} + 13b = 40[/tex]

[tex] - {b}^{2} + 13b - 40[/tex]

[tex] - (b - 5)(b - 8)[/tex]

Set each monomial to zero

Think of a number that adds to 13 and multiply to 40.

Th

[tex]b = 5[/tex]

[tex]b = 8[/tex]

So the answer is 5 and 8. Remember factos are interchangeable so a and b can be either 8 or 5.

Cubed both 5 and 8.

[tex]5 {}^{3} + {8}^{3} [/tex]

4xy=4y

since each friend must get at least a cupcake, 4y must be larger than 8

Step-by-step explanation:

3<3x-2<2x+4

=>

3<3x-2

5<3x

5/3 < x => x > 5/3

=>

3x-2<2x+4

3x-2x<4+2

x<6

Given:

The graphs of two functions f(x) and g(x).

To find:

The correct statement about the functions.

Solution:

In the given graph blue line represents the graph of f(x) and the red line represents the graph of g(x).

From the given graphs it is clear that the graphs of the functions interest each other at point (-2,4). It means,

[tex]f(-2)=4[/tex]

[tex]g(-2)=4[/tex]

So, we conclude that

[tex]f(-2)=g(-2)[/tex]

Thus the option D is correct.

We can check other options.

[tex]f(4)=-14[/tex]

[tex]g(4)=10[/tex]

[tex]f(4)\neq g(4)[/tex]

So, option A is incorrect.

[tex]g(-2)=4[/tex]

[tex]f(4)\neq g(-2)[/tex]

So, option B is incorrect.

[tex]f(2)=-8[/tex]

[tex]f(2)\neq g(-2)[/tex]

So, option C is incorrect.

Therefore, the correct option is D.

Answer:

it's a

Step-by-step explanation:

for these questions try each option till u find the correct one

so since x=5/2 y=4/3

[tex]3( \frac{5}{2} ) + 5( \frac{4}{3} ) = 14 \\ 7.5 + 6.66 = 14 \\ 14.16 = 14[/tex]

which is nearly 14 and same way for the other equation
