Answer:

0.9 of a Liter for the bottle's volume

0.18 L for each cut

180 mL    for each cup.

Step-by-step explanation:

60/100 * 1.5 = 0.6 * 1.5 = 0.90

There were 5 cups

The volume of the bottle was 0.9 liters

1 cup held 0.9 / 5 = 0.18 L

1 Liter = 1000 mL

0.18 L = 1000 *0.18 = 180 mL

Answer:

Step-by-step explanation:

y-x=0.7

y=x+0.7, so lets plug in that into the expressions instead of y

1)

(y-x)=

x+0.7-x=

x+0.7+(-x)=

x+(-x)+0.7=

x-x+0.7=

0.7

2)

(x-(x+0.7))/((x+0.7)-x)=

(x-x+0.7)/(x+0.7-x)=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+0.7+(-x))=

(x-x+0.7)/(x+(-x)+0.7)=

(x-x+0.7)/(x-x+0.7)=

0.7/0.7=

Answer:

x = 6, z=88

Step-by-step explanation:

The angle 92 and z lies on a straight line.

Therefore,

[tex]z + 92 = 180 \\ z = 180 - 92 = 88[/tex]

Same goes for Angle Z and 5x+62.

[tex]z + 5x + 62 = 180 \\ 88 + 5x + 62 = 180 \\ 150 + 5x = 180 \\ 5x = 180 - 150 = 30 \\ x = 30 \div 5 = 6[/tex]

Answer:

7.4 in

Step-by-step explanation:

The diagonal divides the rectangle into 2 right triangles.

The diagonal is the hypotenuse and the length l is a leg ( adjacent) to angle

Using the cosine ratio in the right triangle

cos22° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{l}{8}[/tex] ( multiply both sides by 8 )

8 × cos22° = l , then l ≈ 7.4 in ( to the nearest tenth )

Answer:

The walkway around the pool makes the entire outer dimensions (outer border)  

x+9+2x3=x+15  and  x+8+2x3

hope this helps!  could i get brainliest plz?

The expressions to represent the dimensions of the outside border of the walkway is  (x + 12) meters for the length and (x + 11) meters for the width.

Given area : [tex]x^2 + 17x + 72[/tex]

The factored form of the polynomial is:

[tex]x^2 + 17x + 72[/tex]  = [tex]x^2 + 8x+9x+72[/tex]

                      = x(x+8)+9(x + 8)

                          =(x + 9)(x + 8)

So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.

The length of the walkway = 3 meters wide

So, the length is added to each side of the pool.

Dimensions of the outside border of the walkway:

Length: (x + 9) + 3 = x + 12 meters

Width: (x + 8) + 3 = x + 11 meters

Therefore, the dimensions of the outside border of the walkway are

(x + 12) meters for the length and (x + 11) meters for the width.

Answer: [tex]25^{\circ}[/tex]

Step-by-step explanation:

Given

The highest temperature recorded is [tex]18^{\circ}[/tex]

The lowest temperature recorded is [tex]-7^{\circ}[/tex]

The amount of change between the high and the low temperatures is

[tex]\Rightarrow 18-(-7)=18+7\\\Rightarrow 25^{\circ}[/tex]

Answer:

40%

Step-by-step explanation:

We would use an example

assume the price of the radio is 100

After the initial price reduction, it would be worth (100 - 20%) 80% of the price

0.8 x 100 = 80

After second price reduction it would be worth (100 - 25% ) 75% of the price

0.75 x 80 = 60

Price change = (new price after all the discounts / original price) - 1

(60/100) - 1 = -0.4

The tip was $8.22

Answer:

[tex]\huge\boxed{ \$ \ 8.22}[/tex]

Step-by-step explanation:

Bill = $54.83

Tip = 15 % of 54.83

[% means out of 100, "of" means to "multiply"]

Tip:

= 15% of 54.83

Answer:

Chad is incorrect

Step-by-step explanation:

Since A is in quadrant 2, we know the x must be negative and y is positive. Therefore, if we add a negative sign in front of both x and y, x will become positive, and y will become negative. However, in the 3rd quadrant, both x and y must be negative, which is not the case here. Hence, Chad is wrong.

Answer: 4)y=3x-1

Step-by-step explanation:

The y value relates to the dilatation center, which the line image's equation will be [tex]y = 3x - 1[/tex]. In standard form, [tex]y = mx + b[/tex] y-intercept is represented by the letter b.

[tex]y = 3x - 1[/tex] is the equation of a line.

If somehow the line is dilatable by a factor of 2 and centered at [tex](3, 8)[/tex]. To begin with, we must determine the y-value for which [tex]x = 3[/tex].

[tex]y = 3(3) - 1\\\\y = 9 - 1\\\\y = 8[/tex]

This equation of the line image will be [tex]y = 3x - 1[/tex], because the y value is comparable to the center of dilatation.

Answer:

18cm

Step-by-step explanation:

Answer:

18 cm

Step-by-step explanation:

Step-by-step explanation:

5x-2y=10

x-y=-1

Addition method

multiply the second equation by -2 and add it to the first one

5x-2y=10

-2x+2y=2

Total 3x=12

Divide by sides by 3

x=4

Now multiply the second equation by -5 and add it to the first one

5x-2y=10

-5x+5y=5

3y=15

Divide both sides by 3

y=5

Solutions are x=4 and y=5

2nd method

if x-y=-1, so x=y-1

bring the value of x in the first equation

5(y-1)-2y=10

5y-5-2y=10

put the similar term together

3y=15

Divide both sides by 3

y=5

now bring the value of y in one of the equation

x-y=-1

so x-(5)=-1

x=-1+5

x=4

Solutions are x=4; y=5
