Answer:

y=2.75 units.

Step-by-step explanation:

We have been given that the bottom of a vase is a square. Each side measures y+11 units. The square has a perimeter of 55 units.

Since we know that all sides of square are of equal measure and the perimeter of a square is 4 times the length of each side.

\text{Perimeter of square}=4\times\text{Length of each side}

Upon substituting our given values in above formula we will get,

55=4\times (y+11)  

Upon distributing 4 we will get,

55=4y+44

Upon subtracting 44 from both sides of our equation we will get,

55-44=4y+44-44

11=4y

Upon dividing both sides of our equation by 4 we will get,

\frac{11}{4}=\frac{4y}{4}

2.75=y

Therefore, the value of y is 2.75 units.

Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi 
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.

How do you solve 4b^2+8b+-12=0. Also find the parabole.?
Likurg_2 [28]
First you divide everything by 4 which will become b^2+2b-3=0
Then you can factor this which is
(b-1)(b+3)=0
B=1
B=-3 ... I think that's how you do it

Reduce to simplest form. -\dfrac{1}{3}-\left(-\dfrac{3}{5}\right)=− 3 1 ​ −(− 5 3 ​ )=minus, start fraction, 1, divided by, 3, e
nevsk [136]

Answer:

-1/3 - (-3/5) = 4/15

Step-by-step explanation:

Reduce to simplest form

-1/3 - (-3/5)

= -1/3 + 3/5

Find the Lowest Common Multiple of 3 and 5

Lowest Common Multiple of 3and 5 is 15

Use the LCM to Simplify

= {(-5*1)+(3*3)} / 15

= (-5+9) / 15

= 4/15

Therefore,

-1/3 - (-3/5) = 4/15
