Answer:
2,720
Step-by-step explanation:
First you find 12% of 2,000 by multiplying .12 by 2,000. This gives you 720.
Then you add this to 2,000 to get 2,720
Answer:
C) SSA is NOT a congruent postulate to prove any two triangles congruent to each other.
Step-by-step explanation:
Two Triangles are said to congruent if three sides of one triangle is equal to the 3 corresponding sides of other triangle and 3 angles on one triangle is equal to other 3 corresponding angles.
Two triangles can be proved congruent to each other by
A. SSS (SIDE SIDE SIDE) Postulate
Here, the threes sides of one triangle is equal to the 3 corresponding sides of the other triangle.
B. SAS (SIDE ANGLE SIDE) Postulate
Here, the two sides and any one angle of one triangle is equal to the two corresponding sides and one angle of the other triangle.
C. ASA ( ANGLE SIDE ANGLE) Postulate
Here, the two angles and the included angle of one triangle is equal to the two corresponding sides and included angle of the other triangle.
Hence, from the above option SSA is NOT A congruent postulate to prove any two triangles congruent to each other.
If an odd number of minus signs are involved in a product or quotient, the sign of the result is negative. Otherwise, it is positive.
<u>Examples</u>:
(-1)(-1) = 1
(-1)(-1)(-1) = -1
(-1)/(-1) = 1
(-1)(-1)/(-1) = -1
Answer:
495 milliliters of the 95% mixture are needed.
Step-by-step explanation:
Given that I need a 90% alcohol solution, and on hand I have a 55 ml of a 45% alcohol mixture, and I also have 95% alcohol mixture, to determine how much of the 95% mixture will I need to add to obtain the desired solution, the following calculation must be performed:
55 x 0.45 + 45 x 0.95 = 67.5
25 x 0.45 + 75 x 0.95 = 82.5
15 x 0.45 + 85 x 0.95 = 87.5
10 x 0.45 + 90 x 0.95 = 90
10 = 55
90 = X
90 x 55/10 = X
4,950 / 10 = X
495 = X
Thus, 495 milliliters of the 95% mixture are needed.
Answer:
P = 1/6 or 0.1667
Step-by-step explanation:
Let A,B and C be the three events and 1,2 and 3 be the three dates. The sample space for this problem is:
{A1,B2,C3} {A1,B3,C2} {A2,B1,C3} {A2,B3,C1} {A3,B1,C2} {A3,B2,C1}
There are six possible outcomes and since there is only one correct answer, the possibility of guessing all 3 questions right is:
P = 1/6
P = 0.1667
