Answer:

x=60°

Step-by-step explanation:

Let's say the point where angle x is, be K

Because ABCD and PQRS are paralelograms,

∡PSR = ∡PQR =130°

and

∡DAB=∡DCB=70°

and by angles between parallels

∡SPQ + ∡PQR = 180°

∡SPQ + 130° = 180°

∡SPQ = 50°

by angles opposite by vertex

∡PKC = ∡BKQ = x

So in triangle PKC the sum of all angles must add up to 180°

∡SPQ + ∡PKC + ∡DCB = 180

50 + x + 70 = 180

x = 60

The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 mete

OlgaM077 [116]

Answer:

5 meters

Step-by-step explanation:

If the smallest rectangle has a length of 8 meters, and a perimeter of 24 meters then its width is given by:

$24 = 2*8+2*W_1\\W_1= 4\ meters$

We can conclude that the width is half of the length for both rectangles. Therefore, the width of the larger rectangle, with a perimeter of 30 meters, is:

$30 = 2*W_2+2*L_2\\30 = 2*W_2+4*W_2\\W_2=5\ meters$

The width of the original rectangle is 5 meters.

How can you use properties of multiplication to determine what the factors are

aleksandrvk [35]

Factors can be multiplied together to get the original number.

For example here are the factors of 66.

1 and 66. 2 and 33. 3 and 22. 6 and 11.

1 multiplied by 66 results in the original number 66.

2 multiplied by 33 results in the original number 66.

3 multiplied by 22 results in the original number 66.

<span>6 multiplied by 11 results in the original number 66.</span>

Please help me!!!!!!!!:(

horsena [70]

Answer:

24% chance

Step-by-step explanation:

First, find the total number of graduates in the table, that number is 2610, that will be your numerator.

You will look at the table for the total number of students, that is 10730, that will be the denominator.

Now divide the smaller number/numerator (2610) by the larger number/denominator (10730)

$\frac{2610}{10730}$ = 0.2432432...

Then, multiply by 100 to get the percentage: 24.32432...%

Now, round to the nearest percentage: 24%
