<span>So I only have ones, tens and hundreds block. I need to find a way how can I fit the given number 1 718.
=> Since I have hundreds block, I can divide 1 718 by 100
=> 1 718 / 100, how many 100s are there in 1 718
=> 17 hundreds
=> now we only have 18 left
=> 18 / 10, how many 10s are there in 18
=> 1 tens
=> Now we only have 8 left
=> 8 / 1, how many ones are there in 8
=> 8
=> 17 hundreds, 1 tens, and 8 ones.</span><span>

50 is 40% of what number??????

kvv77 [185]

So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so

50=40%
divide both sides by 2
25=20%

20 times 5=100 so
multiply both sides by 5
125=100%

The length of the rope needed is 15 feet

Given the following parameters;

Height of the pole = 9 foot

The distance from the <u>rope away from the base </u>of the pole is 12 feet

Required

Length of the rope.

To get the length of the rope, you will use the pythagoras theorem expressed as:

c² = a² + b²

Substituting the given parameters:

c² = 9² + 12²

c² =81 + 144

c² = 225

c = √225

c = 15 feet

Therefore the length of the rope needed is 15 feet

The grade point averages (GPA) for 12 randomly selected college students are shown on the right. Complete parts (a) through (c)

Ilya [14]

Answer:

$\bar X =\frac{2.3+3.1+2.8+1.7+0.9+4+2.1+1.2+3.6+0.2+2.4+3.2}{12}=2.29$

$s=1.09$

Step-by-step explanation:

For this case we have the following data given:

2.3 3.1 2.8

1.7 0.9 4.0

2.1 1.2 3.6

0.2 2.4 3.2

Since the data are assumedn normally distributed we can find the standard deviation with the following formula:

$\sigma =\sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}}$

And we need to find the mean first with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X =\frac{2.3+3.1+2.8+1.7+0.9+4+2.1+1.2+3.6+0.2+2.4+3.2}{12}=2.29$

And then we can calculate the deviation and we got:

$s=1.09$

Divide 40x/64y by 5x/8y.

Lemur [1.5K]

<u>Answer:</u>

The correct answer option is C. 1.

<u>Step-by-step explanation:</u>

We are to divide $\frac { 4 0 x } { 6 4 y }$ by $\frac { 5 x } { 8 y }$ .

Rewriting them as a fraction in whole:

$\frac { \frac { 4 0 x } { 6 4 y } } {\frac { 5 x } { 8 y } }$

Changing the division into multiplication by taking the reciprocal of the fraction in the denominator to get:

$\frac { 4 0 x } { 6 4 y }$ × $\frac{8y}{5x}$

Cancelling out the like terms to get:
