Answer:

The chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.

Step-by-step explanation:

Since a chef is going to use a mixture of two brands of Italian dressing, and the first brand contains 6% vinegar, and the second brand contains 11% vinegar, and the chef wants to make 200 milliliters of a dressing that is 9% vinegar, to determine how much of each brand should she use the following calculation must be performed:

100 x 0.11 + 0 x 0.06 = 11

90 x 0.11 + 10 x 0.06 = 10.5

80 x 0.11 + 20 x 0.06 = 10

70 x 0.11 + 30 x 0.06 = 9.5

60 x 0.11 + 40 x 0.06 = 9

200 x 0.6 = 120

200 x 0.4 = 80

Thus, the chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.

Answer:

a. Linear pair theorem

b. x = 40

Step-by-step explanation:

a. x° and (4x - 20)° are angles on a straight line, so, they are a linear pair. Therefore, we would apply the linear pair theorem, which says the sum of a linear pair gives us 180°.

b. x° + (4x - 20)° = 180° (linear pair theorem)

Solve for x

x + 4x - 20 = 180

5x - 20 + 20 = 180 + 20

5x = 200

5x/5 = 200/5

x = 40

Hexagon has six edges. The figure you're trying to figure out is hexagon I guess.

Answer:

D. (8,2)

Step-by-step explanation:

It has one solution =)

Answer (assuming it can be in slope-intercept form):

[tex]y =2x[/tex]  

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:

[tex]m = \frac{(8)-(2)}{(4)-(1)} \\m = \frac{8-2}{4-1} \\m = \frac{6}{3} \\m = 2[/tex]

So, the slope is 2.  

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute 2 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose one of the given points (it doesn't matter which one, the results will equal the same thing) and substitute its x and y values into the formula as well. (I chose (1,2), as seen below.) Then, isolate y to put the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:

[tex]y-(2) = 2 (x-(1))\\y-2 = 2(x-1)\\y -2 = 2x-2\\y = 2x+0\\y = 2x[/tex]

Answer:

£b = £1.68

A = £44.68

Step-by-step explanation:

Given:

A = 5 + 1.9m + b

Where,

A = total cost

m = number of miles travelled

£b = charge for booking online

£5 = fixed charge

A. Harry

A = £29.48

m = 12 miles

£b = ?

A = 5 + 1.9m + b

29.48 = 5 + 1.9(12) + b

29.48 = 5 + 22.8 + b

29.48 = 27.8 + b

29.48 - 27.8 = b

b = 1.68

£b = £1.68

b) If Sue books online and travels 20 miles, what will be

A = 5 + 1.9m + b

= 5 + 1.9(20) + 1.68

= 5 + 38 + 1.68

= 44.68

A = £44.68

Answer:

1

0.8

0.4

Step-by-step explanation:

y = 5x

Substituting '5':

5 = 5x

x = 5/5

x = 1

Substituting 4:

4 = 5x

x = 4/5

x = 0.8

Substituting 2:

2 = 5x

x = 2/5

x = 0.4

Answer:

1) x = 1

2) x = 4/5

3) x = 2/5

Step-by-step explanation:

1) 5= 5x

x = 1

2) 4 = 5x

x = 4/5

3) 2 = 5x

x = 2/5

Answer: 1 =5$

Answer:

14. x=30, y=15, z=165

15. x=10, y=25

Step-by-step explanation:

Answer:

1)

x= 30

y=15

z=150

2)

x= 10

y=25

Step-by-step explanation:

1)

2x+90+x=180

3x+90=180

x= 90/3=30

2y= x

2y=30

y= 30/2=15

2y+z= 180

30+z= 180

z= 150  

2)

3x= 5x-20

5x-3x=20

x=20/2=10

2y+4y+ (5x-20) = 180

6y+30= 180

y= 150/6= 25

I hope im right!!

Answer:

5+11+5+11=32 feet

Answer:

Step-by-step explanation:

the rate of change is 1.60

you can easily see that by comparing the number of chips and the cost

Tiled floor with 225 square tiles means the area of the square room is 225.

Formula needed: A = (side)^2 or in short

A = s^2.

We need to find s.

225 = r^2

sqrt{225} = sqrt{r^2}

15 = r

There are 15 tiles are along an edge of the room.

180-39=151

Answer:

151

Answer:

14

Step-by-step explanation:

You just multiply 2 to (x + 7) which gets you 2x + 14 and then subtract 2x from 2x seeing as they are like terms and you end up with 14.

The answer in this picture is B(143)

Answer:

A

Step-by-step explanation:

180 _80 =100

180_65= 115

180_72 = 108

Then :

108 + 115 + 100 = 323

Then :

360 _ 323 = 37

Then :

180 _37 = 143

X _7 =143

X =150
