Answer:

37 minutes

Step-by-step explanation:

We start by finding the difference between the original amount and what is left

Mathematically, that will be;

20-13.34 = 6.66

To

cents that will be 6.66 * 100 = 666 cents

We now divide by the amount per minute

The amount per minute is 18 cents

Thus, the number of minutes will

be 666/18 = 37

Options:

A. −x2−2x+35=0

B. 5x2+40x+60=0

C. −4x2+24x−20=0

D. x2+12x+20=0

Answer: its not B

============================================================

Work Shown

1 foot = 12 inches

12.75 ft = 12.75*12 inches = 153 inches

The scale of 1 cm : 60 in allows us to form the proportion below

(1 cm)/(60 in) = (x cm)/(153 in)

1/60 = x/153

1*153 = 60*x ..... cross multiply

153 = 60x

60x = 153

x = 153/60

x = 2.55

The length of the component in the drawing is 2.55 cm

Side note: This is equivalent to 25.5 mm since 1 cm = 10 mm (ie you multiply by 10 to go from cm to mm).

Answer:

[tex]\boxed {\boxed {\sf m= - \frac{5}{4} }}[/tex]

Step-by-step explanation:

The formula for slope is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are the points the line passes through.

The line passes through (3,14) and (7,9). Therefore,

[tex]x_1=3 \\y_1=14 \\x_2=7 \\y_2=9[/tex]

Substitute the values into the formula.

[tex]m= \frac{9-14}{7-3}[/tex]

Solve the numerator.

[tex]m=\frac{-5}{7-3}[/tex]

Solve the denominator.

[tex]m= \frac{-5}{4}[/tex]

This fraction is reduced, so it is the answer.

The slope is equal to -5/4

Answer:

$20.64

Step-by-step explanation:

0.20x25.80=5.16

25.80-5.16=20.64

The original price to get entry to a museum is $20.64 .

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let call 'a' be the original price.

if it rose of 20 % , it's mean that it will multiplicate by 0.20

0.20 x 25.80=5.16

a = 25.80 - 5.16=20.64

To find the area of a rectangle, it is length times width (10*3x), and if it equals 40, you could just write that after the equation, and then find out that "x" would equal [tex]\frac{4}{3}[/tex]

Answer:

30x = 40 ; x ≈ 1  

Step-by-step explanation:

[tex]A^{}[/tex] = [tex]l^{}[/tex] [tex]w^{}[/tex]

[tex]l^{}[/tex] = 10 inch.

[tex]w^{}[/tex] = 3x

10(3x) = 40

30x = 40 ; x = [tex]1\frac{1}{3}[/tex] ≈ 1

Answer:

[tex]P = 22.75[/tex]

Step-by-step explanation:

Given:

See attachment for rectangle LINT

Required

Calculate its perimeter

From the attachment:

Considering triangle LYT, we apply Pythagoras theorem.

[tex]LT^2 = LY^2 + TY^2[/tex]

Where:

[tex]LY = 5.2[/tex]

[tex]TY = 3.9[/tex]

The formula becomes:

[tex]LT^2 = 5.2^2 + 3.9^2[/tex]

[tex]LT^2 = 42.25[/tex]

Take positive square root of both sides

[tex]LT = \sqrt{42.25[/tex]

[tex]LT = 6.5[/tex]

Next, we calculate the length of NT.

By comparing triangles LYT and NYT

We make use of the following equivalent ratios to solve for NT

[tex]NT:TY = LT:LY[/tex]

[tex]NT : 3.9 = 6.5 : 5.2[/tex]

Convert to fractions

[tex]\frac{NT}{3.9} = \frac{6.5}{5.2}[/tex]

Make NT, the subject:

[tex]NT = \frac{6.5}{5.2}*3.9[/tex]

[tex]NT = \frac{6.5*3.9}{5.2}[/tex]

[tex]NT = \frac{25.35}{5.2}[/tex]

[tex]NT = 4.875[/tex]

The perimeter (P) is then calculated as:

[tex]P = NT + LT + LI + NI[/tex]

Where

[tex]NT = LI[/tex] and [tex]LT = NI[/tex] -- opposite sides of rectangle.

So:

[tex]P = NT + NT + LT + LT[/tex]

[tex]P = 2NT + 2LT[/tex]

Substitute values for NT and LT

[tex]P = 2*4.875 + 2*6.5[/tex]

[tex]P = 9.75 + 13.0[/tex]

[tex]P = 22.75[/tex]

Hence, the perimeter is 22.75 units
