Translate each of these quantifications into English and determine its truth value. a) ∃x∈R (x3 = −1) b) ∃x∈Z (x + 1 > x) c) ∀x∈Z (x − 1 ∈ Z) d) ∀x∈Z (x2 ∈ Z)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

answer: the answer is 100 x 12,500, which is 1,250,000.

step-by-step explanation: emily solved for a part when she should have solved for the whole.  

875,000 should be the numerator of the equivalent ratio.  

70 x 12,500 is 875,000.
