SOMEONE PLEASE DO THIS IM IN MATH CLASS AND I DONT WANT TO GET CALLED ON BC I DONT KNOW THE ANSWER

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

Answer:

[tex]y = - 4x - 1[/tex]

Answer:

P (getting a head is) = 0.57.

Step-by-step explanation:

The maximum for a probability is 1.

We know that a coin has only 2 sides, either head or tail.

The probability of getting a tail is 0.43 (given).

So, the probability of getting a head is = 1.00 - 0.43 = 0.57.

Answer:

1. y = 0

2. x = -5

3. x = 10

4. y = -12

Missing Details:

Write each fraction in the correct box.

1/8in, 5/8in, 8/16in, 9/16in, 15/16in, 5/6in

Less than: 1/2inch,

Equal to: 1/2inch

Greater than: 1/2inch

Answer:

Less than: 1/2inch---> 1/8 in

Equal to: 1/2inch ---> 8/16 in

Greater than: 1/2inch ---> 5/8in, 9/16in, 15/16in, 5/6in

Step-by-step explanation:

Given

Sizes: 1/8in, 5/8in, 8/16in, 9/16in, 15/16in, 5/6in

Required

Match the size with the correct inequalities

Convert 1/2in to decimal

[tex]\frac{1}{2}\ in = 0.5\ in[/tex]

Next, we convert each size to decimal and compare the decimal equivalent to 0.5in

Convert 1/8in to decimal

[tex]\frac{1}{8}\ in = 0.125\ in[/tex]

0.125 is less than 0.5in

Convert 5/8in to decimal

[tex]\frac{5}{8}\ in = 0.625\ in[/tex]

0.625 is greater than 0.5in

Convert 8/16in to decimal

[tex]\frac{8}{16}\ in = 0.5\ in[/tex]

0.5 is equal to 0.5in

Convert 9/16in to decimal

[tex]\frac{9}{16}\ in = 0.5625\ in[/tex]

0.5625 is greater than 0.5in

Convert 15/16in to decimal

[tex]\frac{15}{16}\ in = 0.9375\ in[/tex]

0.9375 is greater than 0.5in

Convert 5/6in to decimal

[tex]\frac{5}{6}\ in = 0.833\ in[/tex]

0.833 is greater than 0.5in

So, we have:

Less than: 1/2inch---> 1/8 in

Equal to: 1/2inch ---> 8/16 in

Greater than: 1/2inch ---> 5/8in, 9/16in, 15/16in, 5/6in

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: A don't get confused by b

Answer:

The function a^x is increasing, while a^-x is decreasing.

Step-by-step explanation:

The reason for this is the negative. a^x is increasing due to the positive power, while a^-x is decreasing to the negative power.

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

Answer:

A

Step-by-step explanation:

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:

132 miles

Step-by-step explanation:

Given data

scale 1cm:40mi.

this means that

1 cm on the map is equal to 40 miles on

Hence if 1cm rep 40 miles

              3.3cm will rep x

cross multiply

x= 3.3*40

x=132 miles

Answer:

1437.33

Step-by-step explanation:

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

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).
