Goran needs to make a total of 40 deliveries this week. So far he has completed 22 of them. What percentage of his total deliver

jolli1 [7]

Answer: 55%

Step-by-step explanation:

We divide the number of completed deliveries by the total number of expected deliveries and multiply by 100:

22 out of 40= 22/40 ×100

= 0.55 x 100

= 55%

I hope this helps.

The vertices of a quadrilateral in the coordinate plane are known.How can the perimeter of the figure be found?

Yuri [45]

Answer:

Find the length of sides. The sum of these sides is the perimeter of a quadrilateral

Step-by-step explanation:

A quadrilateral is a figure that has four sides. To find the perimeter of any quadrilateral, we find the sum of all four sides.

<u>Given: </u>

The co-ordinates of all vertices of a quadrilateral is known

Perimeter of a quadrilateral

<u>Steps:</u>

1. Find the length of all sides using the straight line distance formula.

2. Add all the sides to find perimeter.

Let us take an example:

In figure the four co-ordinates are as follows:

A(1,3), B(4,2), C(3,0) and D(1,1)

Perimeter of quadrilateral ABCD= AB+BC+CD+DA

To find AB we use straight line distance formula, which is as follows:

AB = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$ where

$x_{1}= 1,x_{2}=4, y_{1}=3, y_{2}=2$

Substituting values we get,

AB= $\sqrt{(4-1)^2+(2-3)^2 }$

AB= $\sqrt{(3)^2+(-1)^2 }$

AB= $\sqrt{(9+1 }$

AB= $\sqrt{10}$

Similarly, we can find length of BC,CD and DA

BC= $\sqrt{5}$ ,CD= $\sqrt{5}$ ,DA=2

Then sum of these sides is perimeter of quadrilateral= $12+2\sqrt{5}$

Note: In this example, the perimeter cam out in roots, due to the values of co-ordinates taken. But the sum can also be a whole number.

Y varies directly with x. If x=6 when y=30, determine y when x=8.

kondaur [170]

Answer:

Y=40

Explanation:

Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8 y must equal 40.

6:30 = 8:40

or

30/6= 5

Y/8= 5

Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.

There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow. You plan to draw 2 marbles from the bag with

schepotkina [342]

<h2>Probability that the second marble will be blue is 0.44</h2>

Step-by-step explanation:

There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow.

Total number of marbles = 10

Given that first marble is yellow.

New total number of marbles = 10 - 1 = 9

Now we have 3 are red, 4 are blue, 2 are green.

Number of blue marbles = 4

We need to find drawing probability of blue marble from 9 marbles.

Let the probability be, p

$p=\frac{\texttt{Total blue marbles}}{\texttt{Total number of marbles}}\\\\p=\frac{4}{9}\\\\p=0.44$

Probability that the second marble will be blue is 0.44
