70 + 20 =90

25/9 x 90 = 250

Answer:

y = 12

Step-by-step explanation:

proportions can be solved by cross-multiplying

to work with smaller numbers, you can simplify [tex]\frac{14}{10}[/tex] to be [tex]\frac{7}{5}[/tex]

[tex]\frac{7}{5}[/tex] = [tex]\frac{y+9}{15}[/tex]

7(15) = 5(y + 9)

105 = 5y + 45

60 = 5y

y = 12

Answer:

  $0.50/lb

Step-by-step explanation:

The increase in cost is $40-25 = $15 for an increase in weight of 50-20 = 30 lb. That makes the cost per pound be ...

  cost/pounds = $15/(30 lb) = $0.50/lb

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.

Answer:

y = -0.5x + 2

Step-by-step explanation:

m=(y2−y1)/(x2−x1)

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

m (slope) = -1/2 or -0.5

y = mx + b (we need b now, y-int)

1 = -0.5(2) + b

b - 1 = 1

b = 2

Now we have the slope (m) and the y-intercept (b), we can rewrite it as such:

y = -0.5x + 2

Hope this helped!

*Remember the equation of a line in slope-intercept form is y=mx+b. In this problem, we found the slope and y-intercept.

Answer:

1 cookie = $1.25    1 cake = $15

Step-by-step explanation:

set up a system of equations:

let x = 1 cookie

let y = 1 cake

3x + 5y = 78.75

8x + 2y = 40

I multiplied the first equation by 2 to get:  6x + 10y = 157.50

I multiplied the second equation by -5 to get:  -40x - 10y = -200.00

If you add both equations, the y-terms will be eliminated

-34x = -42.50

x = 1.25

Plug in 1.25 into equation to find value of y:  8(1.25) + 2y = 40

                                                                           10 + 2y = 40

                                                                            2y = 30

                                                                             y = 15

Answer:   The height is 3  units.

Step-by-step explanation:

By using the give figure we can form right angle out of the whole figure  with a base of  4  and an hypotenuse of 5.

By using this information we can use the Pythagorean Formula to find the height

a^2 + b^2 =c^2     a= base, b = height and c will be the hypotenuse.

4^2 + b^2 = 5^2     Solve for B

16  + B^2 = 25  

-16               -16

    b^2 = 9    

    b = [tex]\sqrt{9}[/tex]  

  b  = 3

The height, h, of the triangular prism is 3 units.

Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.

Given that, vertical cross-section of the triangular prism shown in the given figure is an isosceles triangle.

Here, equal sides of an isosceles triangle is 5 units and base of the isosceles triangle is 8 units.

By using Pythagoras theorem,

5²=h²+4²

25=h²+16

h²=9

h=3

Therefore, the height, h, of the triangular prism is 3 units.

Answer:

380

Step-by-step explanation:

Find 1% of e:

180 / 45 = 4

Find 95% of e:

4 * 95 = 380

Answer:

The correct option is;

B

Step-by-step explanation:

The given system of inequalities are;

5·x - 4·y > 4...(1)

x + y < 2...(2)

Representing both inequalities as a function of "y", gives;

For, 5·x - 4·y > 4...(1), we have;

-4·y > 4 - 5·x

y < 4/(-4) - 5·x/(-4)

∴ y < 5·x/4 - 1

For x + y < 2...(2), we have;

y < 2 - x

Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel

The correct option is therefore, B.

Answer:

15cm and 12cm

Step-by-step explanation:

From the question,The ratio of the length and breadth of a rectangle is 5 to 4

We assume The Lenght of the field= 5x

The breadth = 4x

Area= (5x × 4x)= 180

20x^2= 180

X^2=

X= √9

X=3cm

The Lenght of the field= 5×3= 15cm

The breadth = 4×3=12cm

Step-by-step explanation:

Hey there! If you have any questions, feel free to let me know in the comments.

Step 1: Simplify  20 - 4x - 15 - 4x  to  5 - 8x.

5 - 8x = -6x - 45 + 8x

Step 2: Simplify -6x - 45 + 8x to 2x - 45.

5 - 8x = 2x-44

Step 3: Add 8x to both sides.

5 = 2x - 45 + 8x

Step 4: Simplify 2x - 45 + 8x to 10x - 45.

5 = 10x - 45

Step 5: Add 45 to both sides.

5 + 45 = 10x

Step 6: Simplify 5 + 45 to 50.

50 = 10x

Step 7: Divide both sides by 10.

50/10 = 10x/10

Step 8: Simplify 50/10 to 5.
