Are 2.r = 4 and 4x + 5 = 13 equivalent? ​

Answers

Answer 1

Answer:

Yes, they are equivalent.

Step-by-step explanation:

2r = 4, r = 2. We get this because 4/2 = 2.

4x+5 = 13. Subtract 5 from both sides and we'll get  4x=8. Now divide 8/4 = 2.

So we get 2 = 2, which means that the expressions are equivalent.

Maria correctly concluded that not enough information was provided to construct the requested proof. What extra information would allow Maria to contrast the proof? SA=TR. RS= ST. ASCT is similar to ASCA. SC=5/2BR

Answers

Answer:

Hello your question is incomplete attached below is the complete question

answer: RS = ST ( option b )

Step-by-step explanation:

First we consider Δ SCA and Δ TCB

∠ SCA  = ∠ TCB  ,  ∠CAS = ∠CBT = 90°

if we assume  RS = ST then ΔSRT will be termed an Isosceles triangle with its legs : SR = ST. also vertex S bisects the base of the triangle.

Δ SBR ≅ ΔSBT  from here we can deduce that ; BR = BT

From the assumptions what is actually missing to contrast the proof is : RS = ST

Answers

Complete Question: In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?

*the diagram of the rhombus is in the attachment below

Answer:

m<SRT = 38°

Step-by-step explanation:

A rhombus has 4 equal sides. Also, diagonals of a rhombus bisect each other Therefore:

∆RST form the rhombus given is an isosceles triangle with two equal lengths, ST and SR, and two equal base angles, <T and <R.

Given that <TSR = 104°, thus,

m<SRT = (180 - 104)/2 = 76/2

m<SRT = 38°

Ryan's unpaid credit card balance was $1853.68. His APR is 24.9%. What is his new balance after he makes one new transaction for $178?

Answers

Answer: 2070.14

Step-by-step explanation:

Slide the decimal for 24.9 and get 0.249

1853.68 × 0.249 ÷ 12 = $38.46

you have 0.249 as the monthly rate which means dividing it by 12 is a key to your answer

$1853.68 +38.46 + 178.00 = $2070.14

Answers

Convert 20% to a decimal by dividing by 100, = 0.20

16,000 x 0.20 = 3,200 deposit she paid. Subtract that from the total cost
16,000- 3,200= 12,800

The following probabilities are based on data collected from U.S. adults. Individuals are placed into a weight category based on weight, height, gender and age.

Underweight Healthy Weight Overweight (not Obese) Obese
Probability 0.017 0.377 0.343 0.263

Based on this data, what is the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) range?

Answers

Answer:

the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394

Step-by-step explanation:

  Given the data in the question;

                Underweight   Healthy Weight    Overweight (not Obese)    Obese

Probability       0.017              0.377                        0.343                          0.263

so

P( underweight) = 0.017

P( Healthy Weight) = 0.377

P( Overweight (not Obese) ) = 0.343

P( Obese ) = 0.263

now, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) range will be;

P( weigh less than overweight(but not obese) =  P( underweight) + P( Healthy Weight)

P( weigh less than overweight(but not obese) = 0.017 +  0.377

P( weigh less than overweight(but not obese) = 0.394

Therefore, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394

The first equation of a system of equations is y = -3x + 2. The graph of the system has no solution. Write a possible second equation for the system.

Answers

Answer:

see below.

Step-by-step explanation:

For a system of equation to not have a solution, the pair of lines will never intersect. For two lines to never intersect, their slopes will be parallel.

The second equation can be as simple as y = -3x.

The only equation it cannot be with a slope of -3 is y = -3x + 2. This is because that is the same equation and will therefore have an infinite number of solutions.

Else purchased a prepaid phone card for $15. Long distance calls cost 6 cents a minute using this card. Elsa used her card only once to make a long distance
cal. If the remaining credit on her card is $13.50, how many minutes did her call last?

Answers

Answer:

25 minutes

Step-by-step explanation:

First you subtract the original amount on the card from the remaining amount left.

So you can get the amount of money spent on that call.

$15 - $13.50 = $1.50

Then you divide that number by how much it cost per minute.

$1.50 ÷ 6 = 0.25

Then you get your answer!

The dock foreman gets to work each day at 5:30 A.M. He goes to lunch at 11:01 A.M. and gets back to work at noon. He goes home for the day at 3:20 P.M.

How many hours does the foreman work in a 5−day work week?

Answers

Answer:

The foreman works approximately 44 hours in a 5−day workweek.

Step-by-step explanation:

In one day the dock foreman works the following hours:

[tex]t = (11 h + 01 min*\frac{1 h}{60 min}) - (5 h + 30 min*\frac{1 h}{60 min}) + 15 h + 20 min*\frac{1 h}{60 min} - 12 h = 8.85 h = 8 h + 51 min[/tex]

Now, in 1 5-day work week the man works:

[tex]T = 5*t = 5*8.85 h = 44.25 h = 44 h + 15 min[/tex]

Therefore, the foreman works approximately 44 hours in a 5−day workweek.
