PLZ HELP ME IM ON A QUIZ!!! Which calculation shows the best method for estimating the result of 674 times seven-twelfths?

600 times one-third equals 200
600 times one-half equals 300
690 times one-third equals 230
700 times one-half equals 350

Which calculation shows the best method for estimating the result of 384 divided by three-sixteenths?

400 divided by one-fourth equals 1,600
400 divided by one-fourth equals 100
300 divided by one-third equals 900
300 divided by one-third equals 100

Which expression is most easily solved without the use of a calculator?

(5.6 – 2.9) × 2.2
1.2 × (8.4 – 6.4)
(8.7 – 1) × 5.4
0.9 × (7.8 – 3.9)

What value of x will result in an expression that is the easiest to solve without the use of a calculator?

–1.1(x + 0.56)

x = –1
x = –0.06
x = 0
x = 0.56

a) 32pie square meters

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
