Answer:

2 11/24

Step-by-step explanation:

Answer:

2 11/24

Step-by-step explanation:

3/4 = 18/24

7/8 = 21/24

5/6 = 20/24

18 + 21 + 20 = 59

59/24

59 - 48 = 11

59/24 = 2 11/24

Answer:

(0,4)

Step-by-step explanation:

When you are finding the y-intercept, the x = 0

y = -2x + 4

y = -2(0) + 4

  = 0 + 4

y = 4

Meaning y = (0,4)

[tex]\bigstar{\overbrace{The~y-intercept~of~the~line}}\\\sf{\underline{Solution:-}}[/tex]

Since the equation is written in slope-intercept form (y=mx+b), then we just look at the b term, which stands for the y-intercept.

Notice that the y-intercept is a constant...

Hence, the y-intercept of the line is

Answer:

B. y + 2 = -2(x - 4)

Step-by-step explanation:

First, find the slope (m) of the line using two points in the line, (3, 0) and (4, -2):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 0}{4 - 3} = \frac{-2}{1} = -2 [/tex]

Slope (m) = -2.

Next, substitute (a, b) = (4, -2) and m = -2 into y - b = m(x - a)

Thus:

y - (-2) = -2(x - 4)

y + 2 = -2(x - 4)

Answer:

1/6

Step-by-step explanation:

since 31/6 is 5 1/6

Answer:

1/6

Step-by-step explanation:

let 'x' = number needed to subtract from 31/6 to equal 5

set up equation:

31 - x = 30

 6            6

-x = -1/6

x = 1/6

(30/6 is the same as 5)

check:

31 - 1 = 30

30 = 30

Step-by-step explanation:

Volume of Cone

= 1/3 * (Base Area) * (Height).

Since the radius of the cone is r/2, we have

Base Area = π(r/2)² = πr²/4.

Also the height of the cone is r.

Hence Volume of Cone

= 1/3 * (πr²/4) * (r)

= πr³/12. (C)

Answer:

3.24!

Step-by-step explanation:

Option c is correct, 4.05 multiplied by 0.8 is equal to 3.24.

To calculate 4.05 multiplied by 0.8, you multiply the two numbers together.

First, you can ignore the decimal points and multiply 405 by 8, which equals 3,240.

Next, you count the total number of decimal places in the original numbers.

The decimal point is present in both 4.05 and 0.8, so there are two decimal places in total.

To get the final result, you need to place the decimal point in the product so that it has two decimal places.

Starting from the right side of the product, you place the decimal point two places to the left, resulting in 3.24.

Therefore, 4.05 multiplied by 0.8 is equal to 3.24.

Answer:

The equation will be y=0.50x+5 before plugging 32.50

Step-by-step explanation:

Given that:

Flat fee charged by Shelly = $5.00

Per kilometer charges = $0.50

Let,

x be the number of kilometers driven.

y be the total amount earned.

y = 0.50x + 5

Hence,

The equation will be y=0.50x+5 before plugging 32.50

Answer: for 2 hours of web designing , they charge same amount.

Step-by-step explanation:

Let x = Number of hours.

Total charge = Initial fee + (Charge per hour   x  Number of hours )

For Designer A,

 Total charge = 550 + 120x

For Designer B,

Total Charge = 660+65 x

When the two designers charge the same amount of money, then

550 + 120x = 660+65 x

⇒ 120x-65x= 660-550

⇒ 55x= 110

⇒ x = 2  [Divide both sides by 2]

So, for 2 hours of web designing , they charge same amount.

The decimal value of the number 2(5/8) will be 2.625.

A mixed fraction is one that is represented by both its quotient and remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given mixed fraction is 2( 5/8). The fraction in the decimal form will be written as below:-

2( 5/8) = ( 21 / 8 )

2( 5/8) =  2.625

Therefore, the decimal value of the number 2(5/8) will be 2.625.

Answer:

Cost of 1 hamburger = $1.3

Step-by-step explanation:

Assume;

Cost of 1 hamburger = a

Cost of 1 French fries = b

On first trip

3a + 4b = 7.10......eq1

On second trip

2a + b = 3.40....eq2

From eq2 x 4

8a + 4b = 13.6....eq3

From eq3 - eq1

5a = 6.5

a = 1.3

Cost of 1 hamburger = $1.3

The cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

let

cost of hamburger = x

cost of French pies = y

The equation:

3x + 4y = 7.10 (1)

3x + 4y = 7.10 (1)2x + y = 3.40 (2)

multiply (2) by 4

8x + 4y = 13.6 (3)

3x + 4y = 7.10 (1)

subtract (3) from (1)

8x - 3x = 13.6 - 7.10

5x = 6.5

x = 6.5 / 5

x = 1.3

substitute x = 1.3 into (2)

2x + y = 3.40 (2)

2(1.3) + y = 3.40

2.6 + y = 3.40

y = 3.40 - 2.6

y = 0.8

Therefore, cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

Answer:

8.64. Her work is correct

Step-by-step explanation:

Given the expression to divide 2.16 by 0.25

Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;

2.16/0.25 = (2.16/0.01)÷(0.25/0.01)

(2.16/0.01)÷(0.25/0.01) = 216/25

216/25 = 8.64
