Ms. Jones mowed 1/4 of her lawn. Her son mowed 3/7 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

Her son mowed more of the yard than Ms. Jones did.

32 percent of the yard still needs to be mowed.

Step-by-step explanation:

Find the LGM of 1/4 and 3/7 - that is 28

1/4 to 7/28 and 3/7 to 12/28

3/7 is more than 1/4

Her son mowed 43% of the yard or 7/28 of the yard or 1/4 of the yard.

Ms. Jones mowed 25% of the yard or 12/28 of the yard or 3/7 of the yard.

Together they mowed 68% of the yard or 19/28 of the yard.

They still have 32% of the yard left to mow, or 9/28 of the yard left to mow.

Step-by-step explanation:

Ms.Jones mowed 1/4 of her lawn. Her son mowed 3/7 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
