48feet equals how many yards

Remember

1yard equals 3feet

Let the unknown yard be x

1yard equals 3feet

xyard equals 48feet

Cross multiply

3×X=48×1

X=48/3

X=16

WORTH 100 POINTS!!! PLEASE HELP
musickatia [10]

Answer:

Graph the triangle at points (1,5), (1,8), and (6,8)

Step-by-step explanation:

Since the rule is (x,y) -> (y,x), that just means swapping the value of x and y.

The first point (5,1) has 5 for x and 1 for y. If you swap the values, you get 1 for x and 5 for y, or (1,5).

The second point is (8,6). If you swap x and y you get (6,8). Notice I'm not doing the inverse of each number by making them negative, just swapping the twp values.

The third point is (8,1) and if you swap x and y you should get (1,8).

The transformation rule applies to ALL points, otherwise it wouldn't look right and it wouldnt be transforming.

I hope this helps :)

Devide (a2+ 7a+ 12)÷ (a+3)​
arlik [135]

Answer:

(a - 3) • (a - 4)

Step-by-step explanation:

The first term is,  a2  its coefficient is  1 .

The middle term is,  -7a  its coefficient is  -7 .

The last term, "the constant", is  +12

Multiply the coefficient of the first term by the constant   1 • 12 = 12

Find two factors of  12  whose sum equals the coefficient of the middle term, which is   -7 .

     -12    +    -1    =    -13

     -6    +    -2    =    -8

     -4    +    -3    =    -7    That's it

Rewrite the polynomial splitting the middle term using the two factors, -4  and  -3

                    a2 - 4a - 3a - 12

Add up the first 2 terms, pulling out like factors :

                   a • (a-4)

             Add up the last 2 terms, pulling out common factors :

                   3 • (a-4)

Add up the four terms

                   (a-3)  •  (a-4)

Really hope this helps :)

Answer:

461.875 cubic cm

Step-by-step explanation:

Volume of wood in the block

= volume of cuboid - 3 times the volume of one hemisphere

=lbh - 3\times \frac{2}{3} \pi r^3\\= 20\times 7\times 4 - 2\times 3.14\times (2.5)^3\\= 560 - 6.28\times 15.625\\= 560 - 98.125\\= 461.875 \: cm^3
