Show answer in lowest terms. 25/75+ 25/125=

1 answer:

5 0

Hi Jujub! To find the answer in lowest terms, first you have to find the lowest common denominator. To find this, find the lowest common multiple of 75 and 125, which is 375. Now, to make the common denominator, you have to make equivalent fractions. 375 ÷ 75 = 5, and 5 × 25 = 125. So the new fraction is 125/375. Now the same thing for 25/125. 375 ÷ 125 = 3, and 3 × 25 is 75. So the new fraction is 75/375. Now add the new fractions:
125/375 + 75/375 = 200/375

This answer can be simplified to 8/15.

The group is planning to build a fence around the garden. How many yards of fencing materials do they need for the fence? Show y

garri49 [273]

Answer:

They need 130 yds to build up the fence.

Step-by-step explanation:

Attached you can find a picture that will guide the explanation. We will assume that each line is supposed to be a fence. We will assume also that the diagonals that cross any subfield that has the same vegetable is unnecessary. That is that the diagonal of the tomatoes and the watermelon are not going to be built.

Recall that the red peppers area is a right triangle. So, using pythagora's theorem, we have that

$b^2 +12^2 = 15^2$ so $b=15^2-12^2$

which gives us that b = 9.

On the same fashion, the diagonal of the spinach-celery sector is $\sqrt[]{8^2+6^2}=10$ . Recall that the field is a rectangle, so the perimeter of the outter fence is 2*(12+6)+2*(8+9) = 70 yds. Then, the total perimeter is given by

outter fence (70)+

fence spinach-watermelon (8) +

fence red peppers-watermelon(12)+

fence red peppers-carrots (15)+

fence carrots-tomatoes (9)+

fence celery-tomatoes(6) +

fence spinach-celery(10)

= 130 yds

(if the diagonals of tomatoes and watermelon are added, the same procedure applies. watermelon diagonal is 14.42 yds and tomatoes diagonal is 10.81 yds)

Simplify this expression.

Bond [772]

The correct expression to simplify is:

$1+4.25n + 3/2p -3+(-2p)+5/4n$

Answer:

$5.5n-1/2p-2$

Explanation:

1. Given expression:

$1+4.25n + 3/2p -3+(-2p)+5/4n$

2. Group like terms:

$(1-3)+(4.25n+5/4n)+(3/2p-2p)$

3. Simplify:

1 - 3 = - 2

4.25n + 5/4n = 4.25n + 1.25n = 5.5n

3/2p - 2p = 1.5p - 2p = - 0.5p = - 1/2p

$-2+5.5n-1/2p=5.5n-1/2p-2$

Easy way to remember my 9th multiplication chart

kap26 [50]

If you wanna divide 9's on your fingers, its really easy...
Example: If you wanna do 3x9 you hold up your 10 fingers and put down your fourth finger... it would look like your saying 36, and that is your answer.
Another example: If you wanna do 6x9 you hold up your 10 fingers and put down your 7th finger... It would look like you are saying 63 and that is your answer.
I hope this helps, tell me if you have any questions.

mary has 39 square feet of patio bricks. each square brick has sides 1 foot long. what is the greatest perimeter of a rectangle

bearhunter [10]

-- The smallest perimeter you can make with a certain area
is a circle.

-- The NEXT smallest perimeter with the same area is a square.

 With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be

 (13 bricks) x (3 bricks) .

= (13-ft) x (3-ft)

 Perimeter = (2 x length) + (2 x width)

 = (2 x 13-ft) + (2 x 3-ft)

 = (26-ft) + (6-ft) = 32 feet <== shortest perimeter.

-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.

The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .

 = (39-ft) x (1-ft) .

Perimeter = (2 x length) + (2 x width)

 = (2 x 39-ft) + (2 x 1-ft)

 = (78-ft) + (2-ft) = 80 feet .

What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.
