Step-by-step explanation:

these look easy you can probably just type it into a calculator, just show your work.

not sure where you got 20 from on the first problem it should be 9/12 I think, based on the examples at the top of the page.

1. 9/12

2. 16/22

3. 30/36

4. 28/44

5. 45/55

6. 50/60

The "/" indicates division btw and or fraction

then do the #x#x#x#x# thing you were doing

How many feet long is the fence ?

grandymaker [24]

Answer:

50 feet long

Step-by-step explanation:

Use the Pythagorean theorem to find the value of the missing side. The pythagoreon theorem only works with right triangles such as this one.

a²+b²=c²

Where a and b are length of legs (sides) of a triangle. And c is the length of the hypotenuse. The hypotenuse is the side across from the right angle.

We know by looking at the image posted in the question, that one leg of the triangle is 14 feet. And another leg is 48 feet. (Length of picnic area) (length of campground)

14²+48²=c²

Simplify

196+2304=2500

Find square root of 2500

√(2500)=50

So 14²+48²=50²

The missing side is 50 feet long. The fence is 50 feet long.

Attached is another example.

Please help me. It's urgent

siniylev [52]

Answer:

a) 7/5

Step-by-step explanation:

$y-\frac{y-1}{2}=1-\frac{y-2}{3} \\Through\ the\ butterfly\ method\ of\ resolving\ denominators\ ,\\\frac{2y-(y-1)}{2} = \frac{3-(y-2)}{3} \\\frac{2y-y+1}{2} = \frac{3-y+2}{3} \\\frac{y+1}{2} =\frac{5-y}{3} \\3(y+1)=2(5-y)\\3y+3=10-2y\\3y+2y=10-3\\5y=7\\y=\frac{7}{5}$

Clara's class is going on a trip to the local science museum. Twenty-five students, one teacher, and three parents are going on

yarga [219]

Answer:

$107.50

Step-by-step explanation:

$3.50 = 1 STUDENT

$5.00 = 1 ADULT

TWENTY FIVE STUDENTS = $3.50 × 25 = $87.50

FOUR ADULTS (ONE TEACHER AND THREE PARENTS) = $5.00 × 4 = $20.00

TOTAL COST = $87.50 + $20.00 = $107.50
