What is the answer for
3days : 18hrs

Answers

Answer 1

Answer:

4 : 1

Step-by-step explanation:

(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.

1 day = 24 hours, 3 days = (3 × 24) hours

3 days = 72 hours

Now both the units are same, so we can easily simplify now.

72 hours : 18 hours

36 : 9 = 12 : 3

= 4 : 1 ( Answer)

There were 40 desks in a class. The teacher wanted to arrange the desks in a rectangle with at least 4 desks in each row and column. Which of the following is a possible desk arrangement?
A) 20 rows and 20 columns
B) 5 rows and 8 columns
C) 2 rows and 20 columns
D) 7 rows and 7 columns

Answers

Answer:

B) 5 Rows and 8 Columns

Step-by-step explanation:

First you take the information from the question to know that C is wrong. This is because It has only 2 desks in rows and the question asks for 4 desks in rows and columns. Next you know that you have 40 desks so the two numbers need to multiply to 40. This makes A and D wrong, leaving your answer as B.

What is the density of the glass in 2.5 g/cm in kg/m

Answers

We are given:                                                                                                        

Density of glass in g/cm³ = 2.5

Finding the density in kg/m³:                                                                              

In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg

Converting the g to kg:

2.5 g/cm³ * 1

Since 1kg = 1000g, 1kg/1000g = 1

2.5 g/cm³ * 1kg / 1000g

the g in the numerator and the denominator will cancel out and we will get:

2.5 kg / 1000 cm³

Converting the cm³ to m³:

We know that 1 m³ = 10⁶ cm³

So, 10⁶ cm³ / 1 m³ = 1

Multiplying the density by 1

2.5 kg / 10³ cm³   *   1

2.5 kg / 10³ cm³   *   10⁶ cm³ / 1 m³

the cm³ in the numerator and the denominator will cancel out

2.5 * 10⁶ kg / 10³ m³

2.5 * 10³ * 10³ kg / 10³ m³

2.5 * 10³ kg / m³

2500 kg/m³

12x+5y=95
find the x-intercept
​

Answers

Answer:

(95/12,0)

Step-by-step explanation:

Answer:

(7.916, 0)

Step-by-step explanation:

In order to find the X-intercept, let y=0

12x + 5(0) = 95

12x = 95

95/12x = 7.91666...

Therefore, the x intercept is (7.916, 0)

What step can be taken to solve the equation 10x = 6 + 9x?

Answers

Answer:

subtract 9x from both sides

Step-by-step explanation:

10x = 6 + 9x

9x             9x

19x = 6

0.315789474 = x

.315 = x

Answer:

Subtract 9x from both sides of the equation.

Step-by-step explanation:

To put x by itself, you need to first put all like terms together. So in order to do this, you need to put 10x and 9x together. Since 9x is positive, you need to subtract 9x from both sides of the equation.

Here is how you completely solve the equation:

10x=6+9x10x-9x=61x=6x=6
