jared bought a package of pens containing 20 pens.  If 3/4 of the pens had black ink, how do you determine the number of pens with black ink?

Answers

Answer 1
Answer: well 1/4 of the pens would be 5 (20/4=5)
so 3/4 would be 5x3= 15
15 of the pens have black ink

Answer 2
Answer: wouldn't you take .75 multiplied by 20? .75 is 3/4 obviously.

The probability that a given urine sample analyzed in a pathology lab contains protein is 0.73 (event A). The probability that the urine sample contains the protein albumin is 0.58 (event B). The probability that a sample contains protein, given that albumin is detected, is 1. Which statement is true?a. Events A and B are dependent because P(A|B) =P(A).b. Events A and B are dependent because P(A| B) ≠ P(B).c. Events A and B are dependent because P(A|B) = P(A) + P(B).d. Events A and B are dependent because P(A| B)≠ P(A).e.Events A and B are dependent because P(A|B) = P(A).

Figure ABCD is a rhombus with point A (3, −1). What rule would rotate the figure 270° counterclockwise?(x,y)→(−y,−x)
(x,y)→(−y,x)
(x,y)→(y,x)
(x,y)→(y,−x)

Answers

Answer:

The correct option is 4.

Step-by-step explanation:

Given information: ABCD is a rhombus with point A (3, −1).

If a figure rotated 90° counterclockwise, then

(x,y)\rightarrow (-y,x)

If a figure rotated 180° counterclockwise, then

(x,y)\rightarrow (-x,-y)

If a figure rotated 270° counterclockwise, then

(x,y)\rightarrow (y,-x)

Therefore the rule (x,y)\rightarrow (y,-x) would rotate the figure 270° counterclockwise.

The correct option is 4.

(x,y)→(y,−x)

the average time it takes a swimmer to complete a lap is represented by the variable t. which set of numbers best describes the value of the variable?

Answers

Answer: Rational Numbers

Step-by-step explanation: Rational numbers could be described  as numbers that can be expressed as the quotient or fraction a/b of two integers, a numerator a and a non-zero denominator b. The average lap time of a swimmer will be generally given in a decimal time (i.e  55.47 seconds) these value can be expressed as the quotient or fraction a/b of two integers.

the average time it takes the swimmer is your varible

Which theorem could be used to prove that △ABC ≅ △BAD? A) ASA Congruence B) SAS Congruence C) AAA Congruence D) SSS Congruence

Answers

Answer:

D.SSS Congruence is correct

Final answer:

Without more information, any of ASA, SAS or SSS could potentially prove that △ABC ≅ △BAD. AAA cannot, since it proves only similarity, not congruence.

Explanation:

To determine whether the triangles △ABC and △BAD are congruent, we would need to apply one of the known congruence theorems. This could be the ASA Congruence theorem, the SAS Congruence theorem, or the SSS Congruence theorem.

The AAA Congruence theorem, however, cannot be used to prove triangle congruence. It is important to highlight that it only proves similarity, not congruence.

From the given options, we need to know the exact measures of the angles and sides for △ABC and △BAD to choose the correct theorem to apply. Without any additional information, any of the options ASA, SAS, or SSS could potentially be used.

Answer:

For #9, the part of the expression that represents the quotient is the division problem in parenthesis. Specifically, "(45 ÷ 9)". I believe you only need the division symbol for this, though. Correct me if I'm wrong.

As for #10, the part of the expression representing the product of two factors is 5.2 being multiplied by the variable u. This results in the the term 5.2u, with the coefficient being 5.2 and the variable being u.
