Answer:

4.1271

Step-by-step explanation:

Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.

4.1271

last number is 1 so the cents stays the same

Answer:

1.375

Step-by-step explanation:

11 divided by 8 = 1.375

A proportion is an equation in which two ratios are set equal to each other. Then the value of 1 unit is 1.375.

What is a ratio?

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0.

The value of 8 units is 11.

Then the value of 1 unit will be

The value of 8 units is 11.

Then the value of the 1 unit will be 11/8.

That can be solved as

[tex]\dfrac{11}{8} = 1.375[/tex]

Thus, the value of 1 unit is 1.375.

Line A Gradient: 2

Lime B Gradient: -1

Step-by-step explanation:

✔️Gradient for line A using two points on line A, (0, 1) and (1, 3):

[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 1}{1 - 0} = \frac{2}{1} = 2 [/tex]

Gradient of line A = 2

✔️Gradient for line B using two points on line B, (5, 0) and (3, 2):

[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{3 - 5} = \frac{2}{-2} = -1 [/tex]

Gradient of line B = -1

Answer:

x= -1/3 or x= -3/3

Step-by-step explanation:

Let's solve your equation step-by-step.

6x2+6x−1=−5x−4

Step 1: Subtract -5x-4 from both sides.

6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)

6x2+11x+3=0

Step 2: Factor left side of equation.

(3x+1)(2x+3)=0

Step 3: Set factors equal to 0.

3x+1=0 or 2x+3=0

x= -1/3 or x= -3/3

Answer:

The car must go at 108 km per hour

Step-by-step explanation:

Let us solve the question

∵ A journey by bus takes 45 minutes at 60 km per hour

∴ The speed of the bus = 60 km per hour

∴ The time of the journey = 45 minutes

→ Change the time from minutes to hours

∵ 1 hour = 60 minutes

∴ 45 minutes = 45 ÷ 60 = 0.75 hour

∴ The time of the journey = 0.75 hour

∵ Distance = Speed × Time

→ Substitute the speed by 60 and the time by 0.75

∵ The distance that the bus traveled = 60 × 0.75

∴ The distance that the bus traveled = 45 km

∵ A car goes to do the same journey in 25 minutes

∴ The distance that the car travels = 45 km

∴ The time that the car takes = 25 minutes

→ Divide it by 60 to change it to hours

∵ 25 minutes = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour

∴ The time that the car takes =  [tex]\frac{5}{12}[/tex] hour

→ Use the rule of the distance above to find the speed of the car

∵ 45 = the car's speed ×  [tex]\frac{5}{12}[/tex]

→ Divide both sides by  [tex]\frac{5}{12}[/tex]

∴ 108 = the car's speed

∴ The car's speed = 108 km per hour

∴ The car must go at 108 km per hour

Answer:

78 inches

Step-by-step explanation:

From the above question, our final answer is in inches, hence:

1 foot = 12 inches

The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches.

For painting 2

Converting 3 feet to inches

1 foot = 12 inches

3 feet = x

Cross Multiply

x = 3 × 12 inches = 36 inches

For painting 3

2 feet, 2,inches.

Converting 2 feet to inches

1 foot = 12 inches

2 feet = x

Cross Multiply

x = 2 × 12 inches = 24 inches

Adding up = 24 inches + 2 inches = 26 inches

If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?

This is calculated as:

10 inches + 3 inches + 36 inches + 3 inches + 26 inches

= 78 inches

Therefore, the total width of space she will need = 78 inches
