Before getting to school, fred has a few errands to run. fred has to walk 7 blocks to the museum, and 12 blocks to the library, before walking the final 4 blocks to arrive at school. if fred has already walked 10 blocks, how many more blocks mist he walk before at school?

13

Step-by-step explanation:

7+12=19

19+4=23

23-10=13

13 blocks before he gets to school because you has to walk 23 blocks in total but since he has walked 10 you subtract 10 from 23 and its 13.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
