A teacher asked the class to write an expression that Which of these expressions have an estimated has two decimal factors and an estimated product of 30. product of 30? Check all that apply.
9.7 x 2.84
10.1 x 28.8
O 6.25 X 4.76
35.3 x 1.92

9.7 x 2.84 and 6.25 x 4.76

Step-by-step explanation:

they are the only two that get close to 30 without getting over it

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
