Answer:

$37.8125

Step-by-step explanation:

$2.75 x 12.5 = 34.375

34.375 x 10% = 3.4375

$34.375 + 3.4375 = 37.8125

Answer:

x=5, y=18

Step-by-step explanation:

y=2x+8

x= (y-8)/2

Substitute in second equation,

y= 4((y-8)/2) -2

y= 2(y-8)-2

y= 2y-16-2

16+2=2y-y

18=y

Replace y value in first equation to find x,

18= 2x+8

18-8=2x

10=2x

5=x

Answer:

5:8 po ba ang ratio kasi 5mike

and 8randy old

The proportional relationships that have the same ratio to that of mike and randys age include:

Since Mike is 5 years old and Randy is 8 years old, their ratio is 5:8.

Also, since Sarah is 40 years old and her mother is 64 years old. We can divide their ages by 8. Then the ratio will be 5:8.

Phill is 40 years old and Moleka is 25 years old. We can divide their ages by 5. Then the ratio will be 5:8.

Answer:

$9.03

If you want smallest amount it dollars, you have to go with $9. However, this will only give you a profit of $104.47

Step-by-step explanation:

p = -0.53 +25x - 120

105 = -0.53 +25x - 120

225.53 = 25x

         x = 9.0212

Check work:

105 = -0.53 +25(9.02) - 120

105 ≠ 104.97

Since $9.02 doesn't equal $105 profit, let's add a penny to make it $9.03.

105 = -0.53 +25(9.03) - 120

105 ≠ 105.22      

If you charge $9.03 for each box you will make a profit of at least $105.

Round to smallest amount in dollars:

105 = -0.53 +25(9) - 120

105 ≠ 104.47

Answer:

M(1)

Step-by-step explanation:

(Please see the attached picture to better visualize the number line)

What we know:

- Point A is at -1.5 on the number line

- Point B is at 6 on the number line

- AM:MB=1:2

From the ratio, we automatically know that point M is in between point A and point B on the number line. In other words, point M is greater than -1.5 but less than 6. (-1.5<m<6). We also learn from the ratio that if the distance between point A and point B is divided into thirds, AM would take up one of those thirds and MB would take up two of those thirds.

1. Find the distance between point A(-1.5) and point B(6)

6-(-1.5)

= 6+1.5

= 7.5

2. Divide this distance into thirds

7.5/3

= 2.5

Now, we know that one third of the distance between AM and BM is 2.5.

3. Add 2.5 to point A(-1.5) to find point M (please refer to the picture attached)

-1.5+2.5

= 1

Answer:

2.93

Step-by-step explanation:

3.15×7/100=0.2205

3.15-0.2205=2.9295

The cost of the jeans before tax $2.9295

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

Let 'a' be the original price of the jeans.

Let 'b' be the price of the jeans with tax.

then, b = a + tax

Juan paid $3.15 in tax for the jeans.

The sales tax on a pair of jeans is 7 percent.

First we find the tax on a pair of jeans.

⇒ tax = b × 7%

⇒ tax = 3.15 × (7/100)

⇒ tax = $0.2205

We need to find the cost of the jeans before tax.

Here, b = $3.15, tax amount = $0.2205

⇒ b = a + 0.2205

⇒ 3.15 = a + 0.2205

⇒ a = 3.15 - 0.2205

⇒ a = $2.9295

Therefore, the cost of the jeans before tax $2.9295

50 berries left over

Step-by-step explanation:

55 berries     1700 berries

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

1 jar                   x jars

Using cross products

55x = 1700*1

Divide each side by 55

55x/55 = 1700/55

x = 1700/55

Changing to a mixed number

55 goes into 1700 30 times

30 *55 =16501700-1650 = 50

x = 30 50/55 = 30 10/11

Answer: I am also learning the same thing but this is better than nothing.

f(x,y)→(x-3,-y-2)

Step-by-step explanation:

So basically the base form is f(x,y) that is why I added it there. Then the transformation reflects the shape over the x-axis which changes it from f(x,y)→(x,-y). If you take point A, for example, it is (0,1). When reflected, as the formula shows, it becomes (0,-1) and that is where the negative sign before the y comes from. Then we translate point A left 3 and down 2. That makes the point become (-3,-3) which is where A prime is. That also changes the formula to f(x,y)→(x-3,-y-2). This should work for the ENTIRE shape and ALL THE POINTS. -DooDOoHeaad

Answer:

The range of the function is [-∞,6]

Step-by-step explanation:

Range of a Function

It's the set of values the function takes when x moves into the function's domain.

It can be graphically determined by placing imaginary horizontal lines from minus infinite to plus infinite. Where the line meets the function, that value of y belongs to the range.

The given function is:

[tex]f(x)=-x^2+6x-3[/tex]

Using a graphing tool, we draw the graph shown in the image below.

It can be clearly seen that if we imagine horizontal lines from above y=6 to infinity, they won't ever touch the graph of the function. From y=6 and below, every horizontal line will touch the function one time or twice.

We can conclude the range of the function is [-∞,6]

After translate the sentence into equation, the equation is,

⇒ 8b - 9 = 7

Where, b is any number.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The algebraic expression is,

⇒ Nine less than the product of 8 and a number is 7.

Now, Let a number = b

So, We can formulate the mathematical expression as;

⇒ 8 × b - 9 = 7

⇒ 8b - 9 = 7

Answer: 2

Step-by-step explanation: ( l + w )

Answer:

P(x) = $50.00*x     if    0 ≤ x ≤ 5

P(x) = $48.00*x     if     5 < x

Step-by-step explanation:

A piecewise function is a function that acts differently in different regions of the domain.

In this case we know that:

P = $50.00 per piece if the number of pieces is less or equal than 5.

P = $48.00 per piece if the number of pieces is more than 5.

Then if we define our variable x as the number of pieces of chocolate, we can write the price function as:

P(x) = $50.00*x     if    0 ≤ x ≤ 5

P(x) = $48.00*x     if     5 < x
