Answer:

Triangle A: 38 degrees

Triangle B: Unknown (not enough information)

Triangle C: Unknown (not enough information)

Triangle D: 70 degrees

Triangle E: 40 degrees

Step-by-step explanation:

Work for Triangle A: 90 + 52 = 142. 180 - 142 = 38.

Work for Triangle B: Unidentifiable because there is no indicator to tell you if any of the angles/lines are equal. Generally there will be a "double lined" indicator in the corners of which a triangles angles are equal.

Work for Triangle C: Same as B.

Work for Triangle D: 90 + 20 = 110. 180 - 110 = 70.

Work for Triangle E: 90 + 50 = 140. 180 - 140 = 40.

Answer:

x≤-3      2 ≤x<7  

Step-by-step explanation:

(x^2+x-6) /(x-7) ≤0

Factor the numerator

(x+3)(x-2) / (x-7)≤0

Critical points are

X =-3  X =2  X=7

We need to check the values when

x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  

(x cannot be 7 because then the denominator is zero)

and see when it is less than 0

Substitute a value in and see if factor is positive or negative

x≤-3

(negative)(negative) / (negative) =   negative

-3 ≤x≤2    

(positive)(negative) / (negative) = positive  this range does not work

      2 ≤x<7  

(positive)(positive) / (negative) = negative

x>7

(positive)(positive) / (positive)

Since the beginning of the year, 1982 people have come into a blood bank to donate blood and 340 were found to have high blood p
Alecsey [184]

Answer:

0.1715

Step-by-step explanation:

From previous experience 340/1982 is the past probability that a person has high blood pressure.

The division of that leads to 0.1715 that the next person will have high blood pressure. That number is roughly (very roughly) 1 person in 6. So if 6 people come in 1 will have high blood presure.

This is super hard i needd help
natta225 [31]

Answer:

2587mm^3 approx!

Step-by-step explanation:

first you divide the nut into 6 part(in triangle now, by joining centre to each edge)

let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height

i.e, 1/2×13×15=97.5(mm^2)

now when we consider depth of that traingular part,we will get volume of that part as area×depth

i.e, 97.5×6=585(mm^3)

now volume of all the 6 triangular part is 585×6=3510(in mm^3)

now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately

now reqired volume will be volume of that hexagonal part minus that of circular cavity

=3510-923

=2587mm^3
