Answer:5

Step-by-step explanation:there are 6 boxes between the top of the 3rd box and the bottom of the 10th box.

Since each box is 10 inches tall, the length of the 6 boxes sum up to 60 inches.

and since 12 inches =1 feet,

Then 60 inches = 5 feet

How to solve

Let "y" = the unknown number of feet's

12 inches = 1 feet

60 inches = y

Cross multiply

> 12×y =60×1

> 12y =60

Divide both sides by 12 since you want the value of "y".

> 12y÷12=60÷12

So 12 cancels out leaving the final answer to be:

> y=5

Answer:

<h2>There are 5 feet between the top of the third box and the bottom of the tenth box.</h2>

Step-by-step explanation:

We just have to count how many boxes is between the top of the third one and the bottom of the tenth box, then we transform from inches to feet.

So, the problem says "from the top of the third box" this means that the inches that matters is form the fourth box. "the bottom of the tenth box" means that it's until the ninth box. In total, there are 6 boxes. If each box is 10 inches high, the total distance would be 6(10 inches) = 60 inches.

Now we have the total distance, we transform it to feet. We know that one feet is 12 inches, using the rule of three we have:

60in\frac{1ft}{12in}=5ft

60 inches are equivalent to 5 feet.

Therefore, there are 5 feet between the top of the third box and the bottom of the tenth box.

What is 0.5 divided by 12.5
lisabon 2012 [21]

Answer:

<em>0</em><em>.</em><em>04</em><em> </em><em>o</em><em>r</em><em> </em><em>4</em><em>%</em>

Step-by-step explanation:

<em>-A fraction consists of two numbers and a fraction bar: 0.5/12.5</em>

<em>- The number above the bar is the numerator: 0.5</em>

<em>The number below the bar is the denominator: 12.5</em>

<em>-Divide the numerator by the denominator to get fraction's value: Val = 0.5 ÷ 12.5</em>

<em>Calculate fraction's value.</em>

<em>Divide the numerator by the denominator to get fraction's value:</em><em> </em>

<em>0.5 ÷ 12.5 </em>

<em>=</em><em> </em><em>0.04</em>

<h3><em> </em><em>Calculate the percent value:</em></h3>

<em>Note:100/100 = 100 ÷ 100 = 100% = 1Multiply a number by the fraction 100/100,... and its value doesn't change.0.04 =</em>

<em>=</em><em> </em><em>0.04 × 100/100 </em>

<em>=</em><em> </em><em>(0.04 × 100)/100 </em>

<em>=</em><em> </em><em>4/100 </em>

<em>=</em><em> </em><em>4%;</em>

<h3><em>In other words:</em></h3>

<em>1) Calculate fraction's value.</em>

<em>2) Multiply that number by 100.</em>

<em>3) Add the percent sign % to it.</em>

<em>Answer:</em>

<em>0.5</em><em>÷</em><em>1</em><em>2.5 = 4%</em>

Find the length of line segmentAB which joins the following points.A(10, 14) and B(2,6)​
Helen [10]

Answer:

The equation of the line AB is  y - x -4 = 0

Step-by-step explanation:

The points are A (10,14) and B(2,6)

Now, slope of the line AB :  m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{14 -6 }{10 - 2} = \frac{8}{8}  = 1

So, slope of the equation AB = 1

Now, by SLOPE INTERCEPT FORM:

The equation of line is given as :    y - y0 = m (x-x0)

So,the equation of line AB is  y - 6 = 1(x-2)

or, y - 6 -x + 2 = 0

or, y - x -4 = 0

Hence, the equation of the line AB is  y - x -4 = 0

How many 7-digit phone numbers are possible, assuming that the first digit can’t be a 0 or a 1? (b) re-solve (a), except now ass
sladkih [1.3K]
A. We are going to form 7 digit numbers from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

where the first digit cannot be 0 or 1.

so we have 8 choices for the 1. digit, and 10 choices for all the other 6 digits.

this means there are 8*10*10*10*10*10*10=8* 10^{6} possible numbers.

b.

consider the numbers which start with 911. There are 10*10*10*10=10 ^{4} such numbers, since for the 4th, 5th, 6th and 7th digits we have 10 choices.

then we remove this number, from the one we found in a:

There are in total 8* 10^{6}-10^{4}=7,990,000 numbers which don't start with 911.


Answer:

a.8*10^{6}
b.7,990,000
