Answer 1

Answer:

50=2(10+w)

Step-by-step explanation:

We know that perimeter is equal to the sides of a shape

A rectangle has two of the same length and two of the same width

P=2l+2w

We know the perimeter and length so plug that in and solve for w

50=2(10)+2w

50=2(10+w) - That matches answer choice D

30=2w

w=15

Answer 2

Answer:

Equation: 2 (w + 10) = 50

Step-by-step explanation:

Equation of the perimeter of a rectangle:

=> 2 ( w + l) = P where w= width, l = length, and P = perimeter

Substitute the given values:

=> 2 ( w + 10) = 50

There you have it!

Hope this helps!

What are the coordinates of the vertices of a rectangle with an perimeter of 12 units and an area of 5 sq. units.

Answers

Answer: The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The area of the rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

Step-by-step explanation:

In order to solve this problem you need to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form one the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

= 26 units

The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The rectangle is the quadrilateral with 4 right angles. It could also be defined as, an equiangular quadrilateral, since equiangular means that the all of this angles are = (360°/4 = 90°); and the parallelogram containing a right angle. A rectangle with 4 sides of equal length is a square. The term oblong is occasionally used to refer to a non square rectangle.

If there are 120 6th graders and 30% of them are picked to be participate in the school play, how many students are in the play (provide number only) *

Answers

Answer:

36 6th graders are in the play

Step-by-step explanation:

hope this helps

Answer:

36 students

Step-by-step explanation:

Your output value is 120. You represent the unknown value with x.

120 = 100%.

x = 30%.

120=100%(1)

x = 30%(2)

120/x = 100%/30%

x/120 = 30/100

Therefore, 30% of 120 is 36

We could solve problems like these by plugging in values

Let’s start with A

y = 94x

Let’s use 5, 15, 25 from the table

94(5) = 470
94(15) = 1410
94(25) = 2350

Next, B

y = 5x

5(5) = 25

This is wrong

Next, C

y = x + 470

Let’s try 5

475 = 5 + 470

Close, but wrong

Next, D

10 = 5 + 5

This is wrong, so the answer is A.

the answer is y=94x. pls give brainliest
