Hi, the mean for the numbers is 29, B =D
that is not a function, because there are two outputs for three. two inputs can have one output, but one input cant have two outputs.
A mixed number is a combination of a whole number and a fraction, so in this case we have 8 as the whole part and 0.45 as the fraction, 0.45 is equal to 45/100, and that fraction can be simplified as well, lets see:
8.45 = 8 45/100
= 8 9/20
At least would indicate that Miguel’s amount is greater than or equal to. At least indicates an amount equal to but also larger than the quantity specified. If it were at most, then we would use less than or equal to. Therefore, choose the one with greater than or equal to 250.
Shadow length is proportional to object height.
(tower height)/(tower shadow length) = (tree height)/(tree shadow length)
(tower height)/(72 ft) = (27 ft)/(6 ft)
(tower height) = (72 ft)*(27/6)
(tower height) = 324 ft
The cellular telephone tower is 324 ft tall.
