Answer:

There would be 720 girl shoes

Step-by-step explanation:

So we can make an equation

So we don’t k now how many boy shoes there are so that could be X

We know that girl shoes are 4 times the amount of boy’s shoes

So basically we multiply 4 and x whinch will get you 4x

So we know girl shoes are 4x

Boy shoes are x

Now to make the equation add them together and solve for x

4x+x=900

5x+900

x=180

Now That is only the value of X

So now we know that the amount of shoes boys have are 180

Now multply that by 4 once the girl’s Shoes are 4x and x is 180

180*4 is 720

So 720 girl shoes

The figure shows segment A D with two points B and C on it in order from left to right. The length of segment A B is 22 units, t

valentina_108 [34]

The total length of the segment AD will be 52 units.

The complete question is given below:-

The figure shows segment A D with two points B and C on it in order from left to right. The length of segment A B is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units. What will be the total length of the segment AD?

<h3>What is the length?</h3>

The measure of the size of any object or the distance between the two endpoints will be termed the length. In the question the total length is AD.

Given that:-

Segment AD with two points B and C on it in order from left to right.
The length of segment AB is 22 units, the length of segment BC is 19 units, and the length of segment C D is 11 units.

The total length will be calculated as:-

The total length will be equal to the sum of all the segments of line AD. It will be the sum of AB, BC and CD.

AD = AB + BC + CD

AD = 22 + 19 + 11

AD = 52 units

Therefore the total length of the segment AD will be 52 units.

Part ion even know of the hardest test

ladessa [460]

Given:

The equation of a line is:

$y=-\dfrac{5}{7}x+2$

A line passes through the point (-5,-3) and perpendicular to the given line.

To find:

The equation of the line.

Solution:

Slope intercept form of a line is:

$y=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

We have,

$y=-\dfrac{5}{7}x+2$ ...(ii)

On comparing (i) and (ii), we get

$m=-\dfrac{5}{7}$

We know that the product of slopes of two perpendicular lines is always -1.

$m_1\times m_2=-1$

$-\dfrac{5}{7}\times m_2=-1$

$m_2=\dfrac{7}{5}$

Slope of the required line is $\dfrac{7}{5}$ and it passes through the point (-5,-3). So, the equation of the line is:

$y-y_1=m_2(x-x_1)$

$y-(-3)=\dfrac{7}{5}(x-(-5))$

$y+3=\dfrac{7}{5}(x+5)$

Using distributive property, we get

$y+3=\dfrac{7}{5}(x)+\dfrac{7}{5}(5)$

$y+3=\dfrac{7}{5}x+7$

$y=\dfrac{7}{5}x+7-3$

$y=\dfrac{7}{5}x+4$

Therefore, the equation of the line is $y=\dfrac{7}{5}x+4$ . Hence, option A is correct.

John has 2456 pennies in his coin collection he has the same number of pennies in each of the three boxes estimate to the neares

Keith_Richards [23]

If I read correctly, 2456 pennies needs to be divided simply by 3 then rounded to the nearest hundredth. So you would do 2456/3 3 goes into 24 how many times? Then 3 goes into 5 how many times, then continue the pattern. Once you've gotten a decimal to the thousandth, round the number to the hundredth and there you go
