Retail price = $37.5

Original price = $30

Markup = $7.5

Retail price = cost price + markup

cost price = Original price = $30

Retail price = $30 + $7.5

Retail price = $37.5

Given the word expression:

Triple c, then raise to the 10th power.

Here the exponent of triple c is 10.

To express the above, we have:

Thus, we the expression below:

ANSWER:

Answer: -1 -3/4

Step-by-step explanation:

1.Move terms to the left side

4x^{2}+3=-7x

4x^{2}+3-\left( -7x\right) =0

2.Rearrange terms

4x^{2}+3+7x=0

4x^{2}+7x+3=0

3.Use the quadratic formula

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

4x^{2}+7x+3=0

4.Simplify

Evaluate the exponent

Multiply the numbers

Subtract the numbers

Evaluate the square root

Multiply the numbers

-7+1/8

5.Separate the equations

To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

x=\frac{-7+1}{8}

x=\frac{-7-1}{8}

6.Solve

Rearrange and isolate the variable to find each solution

x=-\frac{3}{4}

x=-1

Total number of drinks sold = 45 + 31 + 47 +27 = 150

Lemonade and ice tea = 45 +27 = 72

Divide the number of lemonades and ice tea drinks sold, by the total number of drinks sold.

72 / 150 = 0.48

Multiply by 100

0.48 x 100 = 48% (option A)

Solution

Note: Equation of a Line os given as

That is m = -4/5

It has x intercept of 3, that is the point (3, 0)

Substituting we have

Given:

a.) A cube is partially filled with 4 mm of water.

b.) The water is 1 mm high

Let's draw the scenario to better understand the problem,

You, Newton, and Descartes walk dogs to earn spending money this summer. You spend 2 times as many minutes walking dogs as Newton. Descartes spends 3 times as many minutes walking dogs as Newton. You, Newton, and Descartes spend 3,030 minutes walking.dogs altogether. How many minutes does Newton walk dogs? ​

Let

x -----> minutes does Newton walk dogs

y ----> minutes does Descartes walk dogs

z ----> minutes does you walk dogs

so

z=2x ------> equation A

y=3x ------> equation B

x+y+z=3,030 ------> equation C

substitute equation A and equation B in equation C

x+(3x)+(2x)=3,030

solve for x

6x=3,030

x=505 minutes

therefore

the answer is

Answer:

- 28

Step-by-step explanation:

-2 + { -3 - [ 7 + 4·( -2 + 5 ) ] } - 4

1)

( -2 + 5 ) = 3

2)

[ 7 + 4·3  ]  = [ 7 + 12 ] = 19

3)

{ -3 - 19 } = - 22

4)

- 2 + ( -22) - 4 = -2 - 22 - 4 = - 28

In a fraction, we have that the top number is the numerator and the bottom number is the denominator.

Also, in a mixed number, we have a whole number together with a fraction, but the denominator still is the bottom number of the fraction

So the statement of the question is FALSE.

From the big triangle we know that:

From the triangle on the right we also know that:

From the triangle on the left we know:

Adding the last two equations we have that:

Equating the last equation with the first one we have that:

Then, the height of the triangle is the squared root of 27.

Once we know the height we can calculate the area.

Therefore the exact value of the area is:

This can be approximated to (rounding on the hundreths):

Given the function:

x^2 + 2x - 8

x^2 - 2x - 8

we are to find the zeros of the function.

To find the zero of a function, we find the root of the numerator.

That is, equsting the numerator to zero

x^2 + 2x - 8 = 0

lets get factor of the above eqaution

= x^2 - 2x + 4x + 8

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

so,

x + 4 = 0 OR x - 2 = 0

x + 4 = 0

x = -4

OR

x - 2 = 0

x = 2

so, x = -4, 2

Therefore the zeros of the function x^2 + 2x - 8 are -4, 2

x^2 - 2x - 8

So, the correct option is D which is -4, 2

The x intercept of a line is where i

The perimeter of a rectangle is the sum of its 4 sides:

EXPLANATION

A special form of average is the Geometric Mean, where we sum the numbers together and then take a square root (for two numbers), cube root (for three numbers), etc.

The geometric mean between 10 and 25 is equal to:

sqrt(10*25)= 15.81

Answer is 5*sqrt(10) or 15.81

A basketball game does not end in a tie. This means that it is either the team wins the game or they draw the game. These outcomes are independent becuase winning one game has no effect on the outcome of the next game. This means that we have a binomial distribution here. the formula for binomial distribution is expressed as

P(x) = nCx * p^x * q^(n - x)

where

n is the number of trials

x is the number of successess

p is the probability of success

q is the probability of failure

We are concerned with the outcome of winning. This means that success is when the team wins. Thus,

p = 4/7

q = 1 - p = 1 - 4/7 = 3/7

n = 15

x = 8

We want to find P(x = 8)

By applying the binomial distribution formula,

P(x = 8) = 15C8 * (4/7)^8 * (3/7)^(15 - 8)

P(x = 8) = 6435 * (4/7)^8 * (3/7)^7

P(x = 8) = 0.194

The probability that in a season of 15 games they will win exactly 8 games is

0.194

Hence, the answer is I(x)=64x³-32x².

In order to determine the time for research, calculate one quarter of the time spend in the project of the company.

Express the time for the project as a normal fraction, as follow:

5 1/3 = 5/1 + 1/3 = (15 + 1)/3 = 16/3

Next, multiply 1/4 (one quarter) by the previous fraction 16/3:

(1/4)·(16/3) = 16/12

simplify the previous fraction:

16/12 = 4/3

as a mixed number the previous result is:

4/3 = 1 1/3

The height of the object based on the information is 1963 feet.

It should be noted that a function is important to show the relationship between the variables given in the data.

In this case, the function given for the height of the object is given as:

h = 16t² + 1899

where t = time

When the time is 2 seconds, the height will be:

h = 16t² + 1899

h = 16(2)² + 1899

h = 64 + 1899

h = 1963

The height is 1963 feet.

Using pythagorean theorem:

Answer:

The relationship between x and y points is a linear relationship of the form:

y = mx + b

where m is the slope of the line, and b is the coordinate y for the y-intercept.

Now, by definition, we have that the slope of the line is given by:

where (X1,Y1) and (X2,Y2) are given points on the graph.

In our case, we can take

(X1, Y1) =(2,-1)

(X2,Y2) = (3,2)

then, te slope of the line would be:

then m = 3 and the new equation for our graph would be:

y = 3x+b

Now, to find b, take any point (x,y) on the graph. In this case, for example

(x,y) = (3,2) and replace this point in the above equation:

2= 3(3) + b

solve for b:

2-9 = b

then b = -7 and we can conclude that the equation for our graph is:

y = 3x-7

We have that the distributive property states that the multiplication is done for all the terms inside the parenthesis. Then we have:

Since

3 · 28 = 84

and

3 · □ = 93

Since 3 · 31 = 93, then

□ = 31

Answer: They are both equal

1 meter = 10 decimeter

We need to convert 100 decimeters to meters

1 meter = 10 decimeter

x meter = 100 decimeter

Cross multiply

x * 10 = 1 x 100

10x = 100

Divide both sides by 10

10x/10 = 100/10

x = 10 meters

Hence, 10 meters is equal to 100 decimeter

Answer: They are both equal

Answer:

[tex]3\, x + (-1)\, y = 1[/tex].

Step-by-step explanation:

Both the slope of this line and the coordinates of a point on this line are given. Therefore, start by finding the point-slope equation of this line: if the slope of a line in a plane is [tex]m[/tex], and this line goes through a point at [tex](x_{0},\, y_{0})[/tex], the point-slope equation of this line will be [tex](y - y_{0}) = m\, (x - x_{0})[/tex].

The slope of the line in this question is [tex]m = 3[/tex]. It is given that this line goes through the point [tex](2,\, 5)[/tex], where [tex]x_{0} = 2[/tex] and [tex]y_{0} = 5[/tex]. Substitute in these values to find the point-slope equation of this line:

[tex](y - y_{0}) = m\, (x - x_{0})[/tex].

[tex](y - 5) = 3\, (x - 2)[/tex].

Rewrite this point-slope equation in the requested format:

[tex]y - 5 = 3\, x - 6[/tex].

[tex]3\, x - 6 = y - 5[/tex].

[tex]3\, x = y + 1[/tex].

[tex]3\, x - y = 1[/tex].

[tex]3\, x + (-1)\, y = 1[/tex].

To solve this problem, we must use the formula:

Where:

• A = final amount = ?,

• P = starting amount = $400.00,

• r = interest rate in decimals = 4% = 0.04,

• n = number of times per year that the interest is compounded = 1 (because interest is compounded annually),

• t = time in years = 2.

Replacing the data of the problem in the equation above, we get:
